Detailed ways

In order to have a further understanding and understanding of the structural features of the present invention and the achieved effects, the preferred embodiments and accompanying drawings are used for a detailed description, as follows:

Example 1

As shown in Figure 1, a dust removal cabinet for a grinding room includes a cabinet body 1 and a control device. The cabinet body has a top wall, side walls and a base. A sink 3, the cabinet body 1 has a dust removal chamber 4.

The dust removal chamber 4 is formed by a base, a part of side walls and a partition device arranged in the cabinet body 1 . One side of the dust removal chamber 4 of the cabinet 1 is provided with a dust suction port 5. Preferably, the dust removal chamber 4 can be set as an open chamber, that is, the dust suction port 5 is connected to the entire side of the dust removal chamber. The walls are the same size.

The dust removal chamber 4 is provided with a two-stage filter device and a water supply system for providing water to the filter device. The first-stage filter device is a vertically arranged water curtain filter device, which is composed of a vertically arranged deflector 6 and a water curtain formed on the side of the deflector 6 opposite to the dust suction port. The water curtain is provided by a water supply system, and the water supply system includes a water supply pipeline 7 , a water outlet 8 connected to the water supply pipeline and an overflow tank 9 . The water outlet 8 is placed in the overflow tank 9, and the overflow tank is arranged on the top of the deflector, the water flows out from the water outlet 8, flows into the overflow tank 9, and the water overflows from the overflow tank 9 and flows down along one side of the deflector Form a water curtain. The second-stage filtering device is a spraying device arranged on the water supply pipeline 7, and the spraying device is more than one spraying head 10, and the number of spraying heads can be set as required to provide a large area of water mist to the dust removal chamber.

The water storage tank 3 is provided with a water pump 11, and the water pump 11 is connected with the water supply pipeline 7, so that the water in the water storage tank 3 can be recycled, and the water storage tank 3 is also provided with a water pump for mixing the sediment and the accumulated water into turbidity. Liquid pump and valve 12 for discharging turbid liquid. In this way, the sediment at the bottom of the water tank 3 can be regularly removed from the valve 12, and sedimentation and separation are carried out outside the cabinet, which not only realizes the recycling of water, but also can easily remove the sedimentation mud in the cabinet.

A water mist condensing device 13 is provided between the partition device and the fan 2 to remove the water mist in the dedusted air. If there is water mist in the rising air filtered by the dust removal chamber, the water mist can be condensed and removed by the water mist condensing device 13 .

The partition device divides the cabinet body 1 into two, and the partition device is used as the top wall of the dust removal cavity, and is composed of an airtight partition plate 14 and a detachable filter paper dust removal device 15 . The airtight partition plate 14 is arranged above the water curtain filter device, so that the air passing through the water curtain filter device cannot rise and leave the dust removal chamber 4, and must continue to flow to the water mist filter device. The detachable filter paper dedusting device 15 is horizontally arranged above the water mist filtering device, so that the air filtered by the water mist can rise and leave the dedusting chamber 4 after being filtered by the horizontal filter paper dedusting device 15 . In this design, the filter paper dedusting device 15 in the separating device is used as the last filter line of defense to filter out the residual dust that may exist. The filter paper dedusting device 15 is arranged horizontally, has a large filtering area, and can be disassembled at will for easy replacement. Specifically, the filter paper dust removal wall is set in a drawer type, and can be set as a single layer or multi-layer superimposed, as shown in Figure 5, and aluminum wave barriers 16 are arranged between each multi-layer.

When in use, the water storage tank 3 is filled with water, and the water pump 11 transports the water to the overflow tank 9 through the water pipe 7. The water in the overflow tank 9 overflows when it is full, and the overflowing water flows down along one side of the deflector 6 A water curtain is formed, and the spray head 10 provides water mist to the dust removal cavity 4 . The fan 2 generates negative pressure in the cabinet 1, and the dust outside the cabinet 1 enters the dust removal cavity 4 from the dust suction port 5. The position of the water curtain filter device corresponds to the dust suction port 5, and the dust enters the cabinet 1. First, After passing through the water curtain filter device, a large amount of dust is filtered by the water curtain on the deflector 6 and deposited in the water storage tank 3 . Since the top of the water curtain filtering device is an airtight baffle 14, the gas with a small amount of dust can only flow to the water mist filtering device at this time, and the remaining dust is filtered out by the water mist in the dust removal cavity. Above is the air-permeable filter paper dedusting device 15, and the air passing through the water mist filter device can rise and leave the dedusting chamber 4 from the filter paper dedusting device 15. Considering that the air filtered by water mist may contain a small amount of water mist, a water mist condensing device 13 is installed above the filter paper dedusting device 15, and the clean air leaves the cabinet through the fan outlet after the water mist is removed by the water mist condensing device 13. Body 1, complete dust removal.

The size of the dust removal cabinet in the grinding room of the present invention can be set according to needs. As shown in FIG. 6 , several cabinets can be integrated in the dust removal cabinet of the grinding room to increase the dust suction strength.

Example 2

As shown in Figure 2, in embodiment 2, the deflector 6 in the water curtain filter device in embodiment 1 is replaced by a filter paper dust removal wall 17, and the filter paper dust removal wall 17 is a breathable air-permeable structure formed by bending and bonding several pieces of filter paper. sex wall. In this embodiment, the water outlet 8 can be directly placed on the top of the filter paper dust removal wall 17, and the water flowing out through the water outlet 8 flows down from the top of the filter paper dust removal wall 17 along the wall to form a water curtain.

All the other are with embodiment 1.

Example 3

As shown in Figure 3, in embodiment 3, the dust removal chamber 4 in embodiment 1 is arranged as a double-sided symmetrical structure. Specifically, dust suction ports 5 are arranged on both symmetrical sides of the dust removal chamber 4, and the water curtain filter The device, the water mist filtering device, and the water supply system are symmetrically arranged in the dust removal chamber, and an airtight baffle 14 is arranged above the two water curtain filtering devices, and a filter paper dust removing device 15 is arranged above the water mist filtering device.

All the other are with embodiment 1.

The dust removal cabinet for the grinding room with such a symmetrical structure realizes simultaneous dust removal on both sides of the cabinet body, further enhancing the dust removal efficiency of the dust removal cabinet for the grinding room.

Example 4

As shown in Figure 4, in embodiment 4, the dust removal chamber 4 in embodiment 2 is arranged in a double-sided symmetrical structure. The device, the water mist filtering device, and the water supply system are symmetrically arranged in the dust removal chamber, and an airtight baffle 14 is arranged above the two water curtain filtering devices, and a filter paper dust removing device 15 is arranged above the water mist filtering device.
