Description

Technical Field

[0001] This utility model relates to the technical field of dust suppression conveying devices, specifically a dust suppression conveying device for the production of water-reducing agents. Background Technology

[0002] The starting materials (such as polyether macromonomers, acrylic acid, initiators, etc.) and the final products (powder type) of water-reducing agents (especially polycarboxylate high-performance water-reducing agents) are usually fine powders, which can easily generate dust during feeding, conveying (especially pneumatic conveying), and packaging.

[0003] Dust-free feeding stations are commonly used conveying devices when feeding water-reducing agents. They are connected to a screw conveyor at the bottom, which can solve the problem of dust dispersion when manually opening bags for feeding. However, in actual production, raw material agglomeration is a common problem, especially for powder raw materials (such as polyether macromonomers and powdered initiators) and some hygroscopic auxiliary materials. Agglomerated raw materials can cause the screw conveyor to jam. At the same time, agglomerated raw materials also affect the reaction and generation of water-reducing agents. Based on this, a dust-reducing conveying device for water-reducing agent production is provided. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-3 In this embodiment of the present invention, a dust-reducing conveying device for the production of water-reducing agents includes a dust-free feeding station 1 and a conveying component 3 installed at the bottom of the discharge port of the dust-free feeding station 1. The hopper of the dust-free feeding station 1 is equipped with an anti-jamming component 2, which is used to filter and crush the agglomeration of the water-reducing agent raw materials.

[0033] Anti-jamming component 2 includes a filter unit and a linkage crushing unit;

[0034] The filtration unit is used to filter the raw materials poured into the hopper of the dust-free feeding station 1;

[0035] The linkage crushing unit utilizes the driving force of the conveying component 3 to crush agglomerated raw materials; the conveying component 3 includes a screw conveyor body 301, a drive motor 302, an active synchronous pulley 303, a driven synchronous pulley 304, and a second synchronous belt 305;

[0036] The screw conveyor body 301 is installed at the bottom of the discharge port of the dust-free feeding station 1. The drive motor 302 is fixed to the outside of the screw conveyor body 301 by a bracket, and the active synchronous wheel 303 is fixed to the output end of the drive motor 302.

[0037] The rotating shaft of the screw conveyor inside the screw conveyor body 301 extends to the outside of the bottom of the screw conveyor body 301 and is fixedly connected to the driven synchronous pulley 304;

[0038] The second synchronous belt 305 is connected to the outside of the driving synchronous pulley 303 and the driven synchronous pulley 304;

[0039] The filtration unit includes an inclined filter plate 201 and a receiving hopper 202;

[0040] The inclined filter plate 201 is fixed inside the hopper of the dust-free feeding station 1 at an inclination, and the top of the inclined filter plate 201 is close to the feeding port of the dust-free feeding station 1.

[0041] The receiving hopper 202 is fixed inside the silo of the dust-free feeding station 1 and is fixedly connected to the bottom of the inclined filter plate 201. The receiving hopper 202 and the inclined filter plate 201 are in a V-shape.

[0042] The raw material is poured onto the surface of the inclined filter plate 201 and slides down the inclined surface of the inclined filter plate 201. The inclined filter plate 201 is used to filter the raw material, and the receiving hopper 202 is used to receive the clumps of the filtered material.

[0043] The linkage crushing unit includes a crushing shaft 204, a crushing blade 205, a transmission synchronous pulley 206, and a first synchronous belt 207;

[0044] The crushing shaft 204 extends obliquely from the outside of the hopper of the dust-free feeding station 1, through the hopper and the inclined filter plate 201, to the top of the receiving hopper 202. The crushing shaft 204 is rotatably connected to the dust-free feeding station 1. The crushing blade 205 is located above the top of the receiving hopper 202 and fixed to the outside of the crushing shaft 204.

[0045] The grinding shaft 204 drives the grinding blades 205 to rotate, which is used to crush the clumps.

[0046] The transmission synchronous pulley 206 is fixed to one end of the crushing shaft 204 located outside the dust-free feeding station 1;

[0047] Two driven synchronous pulleys 304 are installed along the long side of the spiral conveyor shaft. One driven synchronous pulley 304 is connected to the driving synchronous pulley 303 via the second synchronous belt 305, and the other driven synchronous pulley 304 is connected to the driving synchronous pulley 206 via the first synchronous belt 207.

[0048] In this embodiment, the operating principle of this dust-free feeding station 1 is as follows:

[0049] The staff manually pours the water-reducing agent raw material into the hopper of the dust-free feeding station 1. The water-reducing agent raw material rolls down along the inclined surface of the inclined filter plate 201. During this process, qualified water-reducing agent raw material falls down through the filter holes of the inclined filter plate 201, while the clumped water-reducing agent raw material continues to roll down onto the receiving hopper 202, thus achieving the operation of filtering the water-reducing agent raw material.

[0050] At the same time, the drive motor 302 is started. The drive motor 302 drives the screw conveyor shaft to rotate through the transmission of the active synchronous pulley 303, the second synchronous belt 305, and a driven synchronous pulley 304. The qualified water-reducing agent raw material falling downward falls into the screw conveyor body 301, is driven upward by the rotating screw conveyor shaft, and finally falls out through the discharge port of the screw conveyor body 301 to realize the feeding operation.

[0051] In addition, the rotating screw conveyor shaft drives another driven synchronous wheel 304 to rotate, and drives the crushing shaft 204 to rotate through the first synchronous belt 207 and the transmission synchronous wheel 206. The crushing shaft 204 drives the stirring blades 205 to crush the lumps. The crushed qualified raw materials then fall through the filter holes of the inclined filter plate 201. In this way, all the raw materials are conveyed, and at the same time, the lumpy raw materials are prevented from entering the screw conveyor body 301 and causing jamming, which further improves the stability of the device operation.

[0052] It should also be noted that the top of the dust-free feeding station 1 is equipped with a dust removal fan, filter element and other structures, which are used to collect the dust raised during the feeding process. This structure is the conventional structure of the existing general dust-free feeding station on the market, and its operating principle is exactly the same. Therefore, it will not be described in detail here.

[0053] Please refer to this carefully. Figures 2-3 The receiving hopper 202 and the crushing blade 205 are aligned with each other and have an arc-shaped recess. The side plates of the receiving hopper 202 on both sides of the arc-shaped recess are inclined.

[0054] In this embodiment, this structure allows the clumps to concentrate in the rotating area of ​​the crushing blade 205, thereby ensuring the crushing effect of the clumps.

[0055] Please refer to this carefully. Figures 2-3 Inside the dust-free feeding station 1, above the receiving hopper 202, are fixed multiple horizontally distributed protective railings 203.

[0056] In this embodiment, the protective railing 203 can isolate and protect the rotating area of ​​the crushing blade 205. It should be noted that the gap width of the protective railing 203 is larger than the size of common lumps, so that the lumps can fall down smoothly.

[0057] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
