Description

A walking medicine distributing machine for water treatment

technical field

The invention relates to a water pollution treatment device, in particular to a walking medicine distribution machine for water treatment.

Background technique

In recent decades, my country's economy has developed rapidly, and the daily production and living discharges and discharge types of enterprises and residents in the process of economic development have increased, causing pollution to water bodies. Controlling water pollution and improving our environment have become a very important part of the economic development process. One of the methods of water pollution control is to disperse chemicals in the water body. Chemical agents are generally dissolved first and then distributed. For microbial agents, the common method is to directly disperse the powder and granular agents into the water by means of artificial throwing. Such means of drug distribution are difficult to achieve uniform drug distribution, and it is easy to cause local drug overdose and local drug shortage. It is difficult for microbial agents to exert their maximum effect.

Contents of the invention

The purpose of the present invention is to solve the problem that the existing distributing means of water-polluted microbial granular medicine is difficult to ensure uniform medicine distribution, and to provide a walking medicine distributing machine for water treatment that walks on the water surface with a ship and distributes medicine uniformly.

The technical solution adopted by the present invention to solve the technical problem is: a walking medicine distribution machine for water treatment, including a hull, an outer side of the hull is provided with an impeller, and the rotating shaft of the impeller passes through the side wall of the hull and is connected to a gearbox. The output end of the gearbox is connected with a medicine distributing turntable, and the circumference of the medicine distributing turntable is uniformly provided with axially extending medicine grooves, and the outside of the medicine distributing turntable is covered with a shell that fits with the medicine distributing turntable, and the top of the shell is connected There is an upper medicine hopper, and the discharge opening of the upper medicine hopper is strip-shaped in line with the direction of the medicine tank. The width of the discharge opening does not exceed the width of the medicine tank slot. The lower part of the radial side of the shell is opened and connected to the lower medicine hopper. The bottom of the lower medicine hopper is a medicine distributing mouth, and the medicine distributing mouth is arranged on the side of the hull. There is a clearance fit between the medicine distributing turntable and the shell, which does not hinder the rotation and ensures that the medicine will not fall out of the medicine tank easily. During the rotation of the medicine distribution turntable, each medicine tank passes the top in turn. When the medicine tank runs to the top, The medicine granules in the upper medicine hopper fall into the medicine trough, and when the medicine trough rotates to the lower part of one side, the opening of the medicine trough is downward at this time, and the medicine is poured into the lower medicine hopper, and falls into the water from the medicine distribution opening. The impeller drives the medicine distributing turntable to rotate after changing the speed. When the hull is running in the water, the faster the relative speed between the hull and the water flow, the faster the impeller rotates, the faster the medicine distributing turntable rotates, and the greater the dose of medicine is. On the contrary, when the hull decelerates , the dosage is also reduced. After setting the variable speed ratio, the device can distribute the medicine evenly no matter how the speed of the hull changes during the distributing process of the hull, so as to maximize the use efficiency of microbial agents, and the water flow velocity is also considered in the process of uniform medicine dispensing. Influence, to maximize the uniform drug distribution. Preferably, the section of the drug tank is arc-shaped to avoid dead angles.

As a preference, a number of offset V-shaped grooves are evenly distributed on the surface of the impeller, and the V-shaped grooves extend along the axial direction. The V-shaped grooves are provided with blades that can be swung and buckled/deployed, and the swing axis of the blades is along the V-shaped grooves. The bottom of the groove is set. The two side walls of the V-shaped groove are the fastening surface and the expansion surface respectively. The angle between the expansion surface and the radial direction of the impeller is smaller than the angle between the fastening surface and the radial direction of the impeller. When the impeller is close to the fastening surface, The radial distance between the outer end of the blade and the center of the impeller is the smallest, and when the impeller fits the unfolded surface, the radial distance between the outer end of the blade and the center of the impeller is the largest. The lower part of the impeller is submerged in the water. When the hull is moving forward, the blades at the lower part of the impeller are pushed by the water flow and fitted to the V-shaped groove unfolding surface, and are in an unfolded state. Under the thrust of the water flow, the impeller is driven to rotate, thereby driving the medicine distribution turntable to distribute medicine; , the blades at the lower part of the impeller are reversely pushed against the buckling surface of the V-shaped groove, without blocking the water flow, the impeller does not rotate, and the dispensing of medicines stops. The anti-reversal structure of the impeller avoids repeated dispensing of medicines during the ship’s reversing process, resulting in local overdose of medicines, and also prevents the medicine dispensing turntable from being stuck in reverse rotation.

As a preference, take the line connecting the center of the impeller and the bottom of the V-shaped groove as the reference line, the buckling surface of the V-shaped groove and the unfolding surface are located on the same side of the reference line, and the blades are located on the same side of the reference line when they are unfolded and when they are buckled, without crossing The radial critical point makes the impact and energy loss small when the fastening and unfolding states are changed. At the same time, the angle between the working surface of the impeller in the expanded state and the tangent line of the impeller is less than 90 degrees, which plays a role of converging flow and makes full use of the impact force of the water flow.

Preferably, when the blades are attached to the fastening surface, the outer ends of the blades protrude beyond the outer contour of the impeller. The outer end of the blade protrudes slightly from the surface of the impeller when it is fastened, so that the blade can be rapidly unfolded with the help of the water flow when it follows the direction of the water flow.

Preferably, the blade is arc-shaped, the inner arc surface of the blade faces the buckling surface, and the buckling surface is a convex outer arc surface, and the radius of the arc surface of the buckling surface is smaller than the radius of the arc surface of the blade, so that the buckling state of the blade It will not be fully fitted with the fastening surface at the time, resulting in excessive unfolding resistance.

Preferably, the surface of the unfolded surface is adapted to the surface shape of the corresponding position of the blade. The blades in the unfolded state are subjected to relatively high pressure, so the unfolded surface is designed as a plane or an arc with the same curvature as the blades, forming a large area of stable support.

Preferably, the blade is in the shape of a hollow shell with an open outer end, and the hollow blade inner cavity is also sandwiched with an extension leaf that can protrude from the outer end of the blade. Tensioning device, the root of the blade is provided with a number of drainage holes passing through the inner cavity of the blade and the two sides at the position where the blade root fits, and the inner cavity of the blade is provided with a limiting extension leaf on the side of the drainage hole near the outer end of the blade. Limiting column at the retracted position at the root. The limit column restricts the position of the root of the extension leaf, so that the extension leaf is outside the drain hole and will not block the drain hole. When the blade is pushed against the water flow direction to fit the V-shaped groove development surface, one end of the drainage hole is blocked by the development surface. At this time, after the water flow enters the drain hole, the extension leaf is pushed outward inside the blade, so that the extension leaf overcomes the tension of the elastic tensioning device and protrudes from the end of the blade, increasing the stress area of the blade, and the greater the force of the water flow hitting the blade , the longer the protruding length of the extension leaf is, the greater the driving force received by the impeller is; As a drainage channel between the blade and the fastening surface, it accelerates the attachment of the blade to the fastening surface.

Preferably, the length of the extension leaf does not exceed the distance between the limiting post and the outer end of the leaf. The extension leaf can be completely retracted into the inner cavity of the blade when the blade is attached to the fastening surface.

Preferably, the elastic tensioning device includes a pre-tension shaft and a cable arranged in the swing shaft, the pre-tension shaft is coaxially arranged with the swing shaft and pre-tensioned by a torsion spring, and one end of the cable is wound on the pre-tension shaft, The other end is fixed to the root of the elongated leaf. The extension leaf is drawn closer by the pretension and rotation of the pretension shaft. Since the rotation of the pretension shaft is synchronous at both ends, it can ensure that the extension leaf is stretched synchronously in the width direction.

Preferably, there are multiple stay cables arranged at equal intervals at the root of the extension blade, and the stay cables are connected to the root of the extension blade from a position between the drainage holes.

Preferably, the unfolded surface of the lower part of the impeller faces the direction of the bow of the hull.

The invention adopts the impeller driven by the water flow to drive the medicine distributing turntable, so that the medicine distributing speed matches the relative speed of the hull and the water flow, so that the medicine can be distributed evenly; The impeller stops running to avoid repeated dispensing of medicines when the hull travels in reverse.

And take the line connecting the center of the impeller and the bottom of the V-shaped groove as the reference line, and the fastening surface and the unfolding surface of the V-shaped groove are located on the same side of the reference line. The blade 7 is swingably arranged in the V-shaped groove, and the swing axis 10 of the blade is arranged along the groove bottom of the V-shaped groove. When the blade is close to the fastening surface, the radial distance between the outer end of the blade and the center of the impeller is the smallest, and when the impeller is attached to the unfolded surface, the radial distance between the outer end of the blade and the center of the impeller is the largest. The blade 7 is an arc blade, and the inner arc surface of the blade faces the fastening surface 9 . The arc radius of the fastening surface is smaller than the arc radius of the blade, and the arc radius of the unfolding surface is consistent with the arc radius of the blade. When the blade is attached to the fastening surface, it cannot be completely fitted, and the outer end of the blade protrudes from the outer contour of the impeller. When the blade is attached to the unfolded surface, the root of the blade is completely attached to the unfolded surface to form a surface support. A row of drainage holes 15 is provided at the bonding position between the root of the blade and the unfolded surface.
