technical field

The application relates to the field of environmental protection and dust removal, in particular to an environmental protection fan for dust removal.

Background technique

Fans are mainly used in metallurgy, petrochemical, electric power, urban rail transit, textiles, ships and other fields as well as ventilation in various places. Fans are roughly divided into two types: axial fans and centrifugal fans. The air volume and pressure of centrifugal fans are relatively Large, which makes centrifugal fans widely used in factories, mines, tunnels, cooling towers, vehicles, ships and buildings for ventilation, dust removal and cooling.

When used for dust removal in factories, in order to ensure the normal use of the interception net structure during use, the existing centrifugal fans usually use shaking and knocking to shake off the clogging particles on the surface of the interception net structure, but the centrifugal fan sucks and intercepts Dust not only has floating dust particles, but also oil particles with waste heat, which makes the oil particles with waste heat stick to the surface of the intercepting net structure, and it is difficult to achieve normal dredging of the intercepting net structure through a single shaking and tapping operation , so that the structure of the intercepting net is blocked and the ventilation is affected, so the dust removal efficiency of the dust removal fan will be greatly reduced.

To this end, we propose a dust-removing and environmentally-friendly fan, which uses the difference in temperature of the airflow during dust removal to selectively adopt shaking and knocking operations or peeling dredging operations, thereby ensuring the normal ventilation of the internal intercepting structure of the dust removal fan and ensuring dust removal efficiency.

detailed description

The technical solutions in the embodiments of the application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the application. Obviously, the described embodiments are only some of the embodiments of the application, not all of them. Based on The embodiments in the present application and all other embodiments obtained by persons of ordinary skill in the art without creative efforts belong to the protection scope of the present application.

Example 1:

The present invention provides a dust-removing and environment-friendly fan, please refer to Figure 1-4, which includes a centrifugal fan 2 and an air inlet cylinder 3, the top of the centrifugal fan 2 is connected with an air outlet pipe 21, and the front of the centrifugal fan 2 is installed with an inlet The wind cylinder 3, the bottom of the air inlet cylinder 3 is equipped with a dust accumulation base 6, the top wall of the air inlet cylinder 3 is equipped with traction ropes 32 arranged equidistantly, and the tail end of the traction rope 32 is connected with a solid knocking pendant. Ball 31, an intercepting frame is installed inside the air inlet cylinder 3, and an intercepting assembly 5 is arranged on the surface of the intercepting frame;

Specifically, when the centrifugal fan 2 is working to exhaust dust, the airflow entrained by the dust particles passes through the interior of the air inlet cylinder 3 and is intercepted and dedusted by the intercepting frame and then discharged through the air outlet pipe 21 to realize the smooth transfer of the airflow. Under the action of blowing, the knocking ball 31 is lifted obliquely rearward, and the knocking ball 31 suspended in the air after the air flow stops is limited by the traction rope 32, and hits the surface of the intercepting frame during the descent and reset process, causing the impact effect , so that the floating dust particles intercepted on the surface of the intercepting component 5 are knocked off, and the surface of the intercepting component 5 is cleaned accordingly;

Please refer to Fig. 1-8, interception assembly 5 includes breathable mesh bag 51, magnetic attraction assembly 52, reset bar 53, inner adhesive layer 54 and outer adhesive layer 55, and the front of breathable mesh bag 51 is bonded with mouth by glue. The outer bonding layer 55 of glyph, the back side of breathable mesh bag 51 is equipped with hot-melt layer, the back side of breathable mesh bag 51 is glued with the inner bonding layer 54 of mouth-shaped by hot-melt layer, and the front side of breathable mesh bag 51 is installed with The reset strip 53 arranged vertically and horizontally, and the reset strip 53 is located on the inner side of the outer adhesive layer 55; the inside of the breathable mesh bag 51 is placed with a magnetic attraction assembly 52, and the inner wall of the air inlet cylinder 3 is provided with a guide groove 4, and the guide groove 4 The inner wall is inlaid with symmetrically arranged arc-shaped electromagnetic adsorption plates 41 .

Concretely, when encountering the oily dust gas with residual heat, the oily dust particles bonded to the surface of the air-permeable mesh bag 51 are not easy to be knocked off, and the heat in the oily dust gas will make the hot-melt layer lose the adhesive connection Function, the front of the air-permeable mesh bag 51 is tilted inward under the action of the reset strip 53 to form a ball-wrapped structure, and the outer adhesive layer 55 can be used to realize the sealing process of the ball, so that the oily smoke particles wrapped inside are difficult to leak out. Because the breathable mesh bag 51 protrudes from the surface of the intercepting frame in the ball-wrapping state, the inner magnetic attraction assembly 52 and the electromagnetic adsorption plate 41 inside the guide groove 4 overlap in space, and then the electromagnetic adsorption plate 41 in the energized state is opposite to the breathable mesh bag 51. The magnetic attraction assembly 52 of the magnetic suction assembly produces an adsorption effect, so that the ball-shaped air-permeable mesh bag 51 squeezed by the front of the air flow can move laterally to the inner wall side of the air inlet cylinder 3, enter the inside of the guide groove 4, and then be discharged into the inside of the air inlet cylinder 3;

Under the cooperation of the intercepting assembly 5 and the knocking ball 31, the fan can have a corresponding cleaning effect on the floating dust particles with different temperatures and different bonding forces during dust removal, and improve the dust removal efficiency of the fan.

The glue connecting the outer adhesive layer 55 with the surface of the breathable mesh bag 51 is high temperature resistant glue, and the hot melt layer is made of hot melt material with a melting point of 50-60°C.

Specifically, the high-temperature-resistant glue makes the glue on the surface of the outer adhesive layer 55 not hot-melt when it encounters the gas with residual heat, so that the corresponding bonding can be performed normally so that the ball-shaped air-permeable mesh bag 51 can be sealed normally. After being heated for a period of time, the hot-melt layer is in a flow state after the temperature reaches the melting point, and loses the bonding effect, so that the back side of the air-permeable mesh bag 51 is separated from the surface of the intercepting frame, and then the front side is curled inward to form a ball-wrapped shape.

The reset strip 53 bends away from the front of the air-permeable mesh bag 51 when the inner adhesive layer 54 and the surface of the air-permeable mesh bag 51 lose the bonding effect.

Specifically, the reset strip 53 is made of a material plastic strip with certain elasticity. When the air-permeable mesh bag 51 is connected to the surface of the intercepting frame through the inner adhesive layer 54, the reset strip 53 is passively bent into an arc, and then loses the inner When the adhesive layer 54 is restrained, it can be tilted inward under the action of elasticity, so as to facilitate the bonding and sealing of the outer adhesive layer 55 .

The magnetic attraction assembly 52 is composed of an outer bag and an inner filling material located inside the outer bag. The outer bag is made of a water-soluble film, and the inner filling material is a strong magnetic powder.

Specifically, the force adsorption between the strong magnetic powder and the electromagnetic adsorption plate 41 can assist the ball-shaped air-permeable mesh bag 51 to overcome the friction with the new air-permeable mesh bag 51 surface on the surface of the intercepting frame when it is subjected to wind force and then attract the ball-shaped air-permeable mesh bag 51. The air-permeable mesh bag 51 absorbs and moves to the position of the inner side wall of the air inlet cylinder 3, so as to realize the cleaning of the intercepting frame surface.

In addition, the water-soluble film enables the magnetic attraction assembly 52 to dissolve after being dropped into water to release the strong magnetic powder, and then the strong magnetic powder can be recovered and reused through the magnetic block.

The edge of the outer adhesive layer 55 is attached to the surface edge of the breathable net bag 51 , and the cross-sectional area of the outer adhesive layer 55 is larger than that of the inner adhesive layer 54 .

Specifically, a multi-layer interception assembly 5 is arranged on the surface of the interception frame, and then after the outermost breathable mesh bag 51 forms a wrapping ball and separates, there will be an interception assembly 5 for dust removal and interception operation. In addition, due to the adjacent outer bonding There is a difference in size between the layer 55 and the inner adhesive layer 54, and a release layer corresponding to the outer adhesive layer 55 is arranged on the outside of the inner adhesive layer 54, so that the inner adhesive layer 54 on the back side of the front air-permeable mesh bag 51 The outer adhesive layer 55 on the front side of the air-permeable mesh bag 51 at the rear will not overlap when glued together, so that the air-permeable mesh bag 51 can be easily detached.

The bottom end of the guide groove 4 runs through the bottom of the air inlet cylinder 3, and the length of a group of electromagnetic adsorption plates 41 is 0.4 of the overall arc length of the guide groove 4, and the top of the dust accumulation base 6 is provided with a strip-shaped feed port 61, And the orthographic projection of the part of the guide groove 4 penetrating through the air inlet cylinder 3 on the surface of the dust accumulation base 6 coincides with the edge of the feed opening 61 .

Specifically, the arc length of the electromagnetic adsorption plate 41 is limited so that the magnetic adsorption is limited to the inner part of the air inlet cylinder 3, and will not spread to the upper area of the air inlet cylinder 3. 41 enters the inside of the feed port 61 through the penetrating part after the power is cut off, and then falls into the inside of the sliding drawer 62 to realize dust accumulation treatment.

The inside of the air inlet cylinder 3 is equipped with a windshield ring 33 positioned at the front of the guide groove 4, and the width of the overlapping area between the windshield ring 33 and the intercepting frame is 2 cm.

Specifically, the design of the wind-shielding ring 33 can make a certain wind-shielding area exist in front of the guide groove 4 , thereby reducing dust accumulation on the inner wall of the guide groove 4 .

Please refer to FIGS. 11-12 , the inner adhesive layer 54 is fitted with four groups of thermal expansion strips 541 connected end to end, and the thermal expansion strips 541 cover the surface of the inner adhesive layer 54 in section after thermal expansion.

Specifically, the surface of the thermal expansion strip 541 is covered with a layer of lubricating oil, and when the inner adhesive layer 54 is separated from the front of the rear breathable mesh bag 51, it is heated and expands to cover the inner adhesive layer 54, so that the inner adhesive layer 54 cannot function. The effective bonding effect can further reduce the bonding effect between the exposed inner adhesive layer 54 and the surface of the intercepting frame in the state of wrapping the ball, so as to facilitate the smooth movement of the wrapping ball.

Referring to FIGS. 9-10 , the surface of the outer adhesive layer 55 away from the air mesh bag 51 is connected with a release paper 552 , and the surface of the release paper 552 away from the air mesh bag 51 is connected with a heat shrinkable film 551 .

Concretely, the bonding effect between the release paper 552 and the outer adhesive layer 55 is small, and it is convenient to separate. When the ventilation is intercepted, the heat-shrinkable film 551 drives the release paper 552 to cover the outer adhesive layer 55, so that floating dust will not adhere to the surface of the outer adhesive layer 55 and damage the bonding effect of the outer adhesive layer 55.

The rear of the centrifugal fan 2 is equipped with a motor 1 through a shaft, and a sliding drawer 62 is fitted inside the dust accumulation base 6. The inside of the sliding drawer 62 is filled with water, and the surface of the motor 1 is installed with a motor that extends to the inside of the sliding drawer 62. The heat conducting rod is connected with the sliding drawer 62 in a sliding and sealing manner.

Specifically, the heat generated by the motor 1 is transferred to the water body inside the sliding drawer 62 through the heat conduction rod, and the water body can reduce the possibility of dry floating dust to generate dust, and can also promote the hydrolysis of the water-soluble film, which is convenient for subsequent recovery of powerful magnetic powder.

The above is only a preferred embodiment of the present application, but the scope of protection of the present application is not limited thereto. Anyone familiar with the technical field within the technical scope disclosed in this application, according to the technical solutions of this application Equivalent replacements or changes thereof shall fall within the scope of protection of the present application.
