Abstract
Description
Technical Field
[0001] The present application relates to a discharge hopper, and more particularly to a dust-proof hopper. Background Art
[0002] Heavy calcium carbonate is ground from natural carbonate minerals such as calcite, marble, and limestone. It is a commonly used powdery inorganic filler and is widely used in the rubber industry, plastic industry, paint industry, construction industry, etc. It has the advantages of high chemical purity, large inertness, difficult chemical reaction, and good thermal stability. In the preliminary preparation of heavy calcium carbonate production, steps such as transportation, unloading, raw material sorting, and storage are involved. During the unloading process, the raw materials are directly poured into an underground hopper by a self-unloading truck. During this process, dust is easily generated, which will pollute the production environment and harm the physical health of the staff. Summary of the Utility Model
[0003] To solve the above deficiencies of the prior art, the present application provides a dust-proof hopper, which can limit the movement range of dust and then remove dust to avoid affecting the surrounding environment.
[0004] To achieve the above object, the present utility model adopts the following techniques:
[0005] A dust-proof hopper includes a hopper body, and a dust-proof cover is provided outside the hopper body. The dust-proof cover includes four side plates and a top plate. The four side plates correspond to the four side faces of the hopper body. There is a predetermined height between the top plate and the top of the hopper body. A water inlet pipe is provided on the top of the top plate. A cavity is provided inside the water inlet pipe of the top plate. Nozzles are provided on the bottom of the top plate. The water inlet pipe, the cavity, and the nozzles are sequentially connected. Filter plates are symmetrically provided on two side plates parallel to the width direction of the hopper body. The filter plates are relatively movable along the length direction of the hopper body and are provided above the hopper body. The filter plates include a filtering layer and a water-absorbing layer. The filtering layer is provided on the upper part of the water-absorbing layer. A feed inlet is provided through one of the side plates parallel to the length direction of the hopper body.
[0006] The beneficial effect of the present utility model is that the present utility model provides a dust-proof hopper. The dust generated by pouring materials is restricted within the dust-proof cover by the dust-proof cover to prevent it from escaping to the outside. Then, through the settings of the water inlet pipe, the cavity, the nozzles, and the filter plates, the dust floating in the dust-proof cover can be carried by water mist to the top of the filter plates. The water enters the water-absorbing layer, and the dust is retained on the top of the filtering layer. By removing the filter plates, the dust can be swept out and recycled, improving the utilization rate of raw materials while removing dust. Description of the Drawings

[0012] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the following will describe the implementation manners of the present utility model in detail with reference to the accompanying drawings. However, the embodiments described herein are only a part of the embodiments of the present utility model, rather than all of the embodiments.
[0013] The embodiment of the present application provides a dust-proof hopper. As Figures 1-4 shown, it includes a hopper body 1, and a dust-proof cover 2 is provided outside it. The dust-proof cover 2 is used to confine dust within the dust-proof cover 2 when pouring materials into the hopper, avoiding the escape of dust to the outside. The dust-proof cover 2 includes four side plates 21 and a top plate 22. The four side plates 21 correspond to the four side faces of the hopper body 1. There is a predetermined height between the top plate 22 and the top of the hopper body 1. A water inlet pipe 221 is provided on the top of the top plate 22. A cavity 222 is provided inside the top plate 22. A nozzle 223 is provided at the bottom of the top plate 22. The water inlet pipe 221, the cavity 222 and the nozzle 223 are connected in sequence. Filter plates 3 are symmetrically provided on two side plates 21 parallel to the width direction of the hopper body 1. The filter plates 3 are arranged to move relatively along the length direction of the hopper body 1, and the filter plates 3 are arranged above the hopper body 1. The filter plate 3 includes a filtering layer 31 and a water-absorbing layer 32. The filtering layer 31 is arranged on the top of the water-absorbing layer 32. A feed inlet 211 is provided through one of the side plates 21 parallel to the length direction of the hopper body 1.
[0014] During application, move the filter plates 3 along the length direction of the hopper body 1 to the outside to expose the feed channel of the hopper body 1, and then pour materials into the hopper body 1 through the feed inlet 211.
[0015] After the material pouring is completed, move the filter plates 3 along the length direction of the hopper body 1 to the inside to close the feed channel of the hopper body 1 with the two filter plates 3. At this time, most of the dust is in the area formed by the dust-proof cover 2 and the hopper body 1. Inject water into the cavity 222 through the water inlet pipe 221, and finally spray it out from the nozzle 223. The water mist sprayed out by the nozzle 223 will move downward together with the floating dust until it falls on the top of the filter plates 3. Then the dust will be filtered by the filtering layer 31, and the water will be absorbed by the water-absorbing layer 32.
[0016] When all the dust to be internally dispersed is carried to the top of the filter plate 3 under the action of the water mist, the filter plate 3 is moved outward along the length direction of the hopper body 1, so that the filter plate 3 moves to the outside of the dust-proof cover 2, and then the dust falling on the filter plate 3 can be swept out and recollected.
[0017] Specifically, as Figure 3 shown, a rotating shaft 4 is arranged along the length direction of the hopper body 1 in the feed inlet 211, and a rotating plate 5 is fixedly arranged on the rotating shaft 4. The rotating plate 5 can realize the switching between the open state and the closed state of the feed inlet 211. When the feed inlet 211 is in the open state, it is convenient to pour materials into the hopper body 1 through the feed inlet 211 during feeding. When the feed inlet 211 is in the closed state, it can prevent dust from escaping to the outside through the feed inlet 211 during dust removal. Moreover, the rotating plate 5 rotates together with the rotating shaft 4, and the rotating plate 5 is used to provide a feed channel. The rotating shaft 4 passes through the hopper body 1 and is connected to a rocker 6, and the rocker 6 is used to control the rotation of the rotating plate 5.
[0018] Preferably, as Figure 3 shown, the height of the rotating plate 5 above the rotating shaft 4 is greater than or equal to the height of the rotating plate 5 below the rotating shaft 4. The top of the rotating plate 5 rotates towards the hopper body 1 until the rotating plate 5 above the rotating shaft 4 abuts against a certain part of the hopper body 1 and cannot rotate further. At this time, the end face of the rotating plate 5 facing the outside can be used as an auxiliary feeding channel. The top of the rotating plate 5 is located above the feeding channel of the hopper body 1, that is, one end of the top of the rotating plate 5 is connected to the hopper body 1, and one end of the bottom of the rotating plate 5 is connected to the unloading vehicle. Since the rotating plate 5 is in an inclined state at this time, the materials from the unloading vehicle can enter the hopper body 1 more conveniently through the rotating plate 5, thus realizing the pouring of materials.
[0019] Preferably, as Figure 1 、 Figure 2 and Figure 4 shown, the end face of the rotating plate 5 facing the outside is an arc surface. Since the end face of the rotating plate 5 facing the outside can be used as an auxiliary feeding channel, the setting of the arc surface with a lower middle and higher sides is beneficial to the materials being more concentrated in the middle of the arc surface when on the rotating plate 5 for falling, and can prevent the materials from spilling to both sides of the rotating plate 5.
[0020] Specifically, as Figures 1-3 shown, two guide rods 7 are arranged along the length direction of the hopper body 1 inside the hopper body 1. One of the guide rods 7 is a double-headed screw, and the rotation of the double-headed screw is driven by a motor 8. The two ends of the filter plate 3 are sleeved on the two guide rods 7. By driving the motor 8, the two filter plates 3 can be moved inward or outward along the length direction of the hopper body 1 at the same time.
[0021] Specifically, as Figure 1 、 Figure 2 and Figure 4As shown, a water outlet hose 9 is provided at one end of the water absorption layer 32 facing the outside. The water outlet hose 9 is used to discharge the water in the water absorption layer 32. The water outlet hose 9 can be connected to a water storage tank, the water storage tank is connected to a water pump, and the other end of the water pump is connected to the water inlet pipe 221, so as to realize the recycling of water. As another preference, the water absorption layer 32 can also be used as a placement groove for water absorption materials.
[0022] In application, the above are only the preferred embodiments of the present application and are not used to limit the present application. Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application.
