Description

Technical Field

[0001] This utility model relates to the field of cement grinding aid technology, specifically to a raw material impurity removal device for cement grinding aid production. Background Technology

[0002] Cement grinding aids are chemical additives that are added in small amounts during the grinding process of cement clinker. These additives can significantly improve grinding efficiency or reduce energy consumption without impairing the performance of cement. However, the production of cement grinding aids requires the use of a purification device to filter out impurities from the raw materials.

[0003] Existing impurity removal devices typically involve directly pouring raw materials into them for impurity removal. However, in actual use, it is not possible to quickly and easily stir the raw materials, which leads to the accumulation of raw materials in the impurity removal box and makes it impossible to clean the filter screen, thus reducing the working efficiency of the impurity removal device.

[0004] Therefore, we urgently need to provide a raw material impurity removal device for cement grinding aid production. Utility Model Content

[0005] The purpose of this invention is to provide a raw material impurity removal device for cement grinding aid production, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a raw material impurity removal device for cement grinding aid production, comprising an impurity removal box and a support leg, wherein the impurity removal box is provided with an impurity removal structure;

[0007] The impurity removal structure includes an impurity removal mechanism and an auxiliary mechanism;

[0008] The impurity removal mechanism includes a motor, a rotating rod, a stirring rod, a cleaning brush, and a mounting plate. The output end of the motor is connected to the bottom of the rotating rod. The outer wall of the rotating rod is connected to the inner wall of the stirring rod. The outer wall of the rotating rod is connected to the inner wall of the cleaning brush. The inner wall of the impurity removal box is connected to one end of the mounting plate. A guide rod is fixedly installed on one side of the mounting plate. A connecting plate is slidably connected to the outer wall of the guide rod. A filter screen is pressed against the inner side of the connecting plate. A limit plate is fixedly installed at the bottom of the filter screen. A fixing bolt is threadedly connected to the inner wall of the limit plate.

[0009] A further improvement is that the number of stirring rods is four, and the stirring rods are symmetrically distributed on the outer wall of the rotating rod. The number of cleaning brushes is two, and the cleaning brushes are symmetrically distributed on the outer wall of the rotating rod. This allows for quick and convenient stirring and filtering of raw materials, and better cleaning of the filter screen surface, thus improving its usability.

[0010] A further improvement is that the number of mounting plates is four, which are symmetrically distributed on the inner wall of the impurity removal box, and the number of connecting plates is two, which are also symmetrically distributed on the inner wall of the impurity removal box. This allows for quick and convenient assembly and disassembly of the filter screen, thereby enabling better filtration of raw materials.

[0011] A further improvement is that a spring is fixedly installed between the bottom of the connecting plate and one side of the mounting plate, and there are two filters, which are symmetrically distributed on the inner side of the connecting plate, so as to better vibrate the filters up and down, thereby effectively preventing the filters from becoming clogged.

[0012] A further improvement is that the auxiliary mechanism includes a magnetic separator roller, a first belt, a second rotating rod, a cam, and a second belt. The outer wall of the magnetic separator roller is connected to the outer wall of the second rotating rod via the first belt. The outer wall of the second rotating rod is connected to the inner wall of the cam. The outer wall of the second rotating rod is connected to the second belt.

[0013] A further improvement is that there are two rotating rods, which are symmetrically distributed on the inner wall of the impurity removal box. There are four cams, which are symmetrically distributed on the outer wall of the two rotating rods. The two rotating rods are connected by a belt, which enables the cams to rotate quickly and easily, thereby causing the filter screen to vibrate and filter the raw materials better.

[0014] A further improvement is that the bottom of the impurity removal box is connected to the top of the support leg, the bottom of the impurity removal box is connected to the top of the motor, and the inner wall of the impurity removal box is rotatably connected to both ends of the magnetic separation roller.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This raw material impurity removal device for cement grinding aid production enables rapid and convenient filtration of raw materials through its impurity removal mechanism. It also agitates the raw materials, effectively preventing their accumulation and cleaning the filter screen surface. This solves the problem of raw materials accumulating in the impurity removal box and the inability to clean the filter screen due to the inability to quickly and conveniently agitate them, thus improving the working efficiency of the impurity removal device.

[0017] 2.

[0025] 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.

[0026] Please see Figures 1-6 This utility model provides a technical solution:

[0027] Example 1:

[0028] A raw material impurity removal device for cement grinding aid production includes an impurity removal box 1 and a support leg 2. The impurity removal box 1 is equipped with an impurity removal structure.

[0029] The impurity removal structure includes an impurity removal mechanism 3 and an auxiliary mechanism 4;

[0030] The impurity removal mechanism 3 includes a motor 301, a rotating rod 302, a stirring rod 303, a cleaning brush 304, and a mounting plate 305. The output end of the motor 301 is connected to the bottom of the rotating rod 302. The outer wall of the rotating rod 302 is connected to the inner wall of the stirring rod 303. The outer wall of the rotating rod 302 is connected to the inner wall of the cleaning brush 304. The inner wall of the impurity removal box 1 is connected to one end of the mounting plate 305. A guide rod 306 is fixedly installed on one side of the mounting plate 305. A connecting plate 307 is slidably connected to the outer wall of the guide rod 306. A filter screen 308 is pressed and contacted on the inner side of the connecting plate 307. A limiting plate 309 is fixedly installed at the bottom of the filter screen 308. A fixing bolt 310 is threadedly connected to the inner wall of the limiting plate 309.

[0031] In this embodiment, there are four stirring rods 303, which are symmetrically distributed on the outer wall of the rotating rod 302. There are two cleaning brushes 304, which are symmetrically distributed on the outer wall of the rotating rod 302. This allows for quick and convenient stirring and filtering of raw materials, and better cleaning of the surface of the filter screen 308, thus enabling better use.

[0032] Furthermore, there are four mounting plates 305, which are symmetrically distributed on the inner wall of the impurity removal box 1, and two connecting plates 307, which are symmetrically distributed on the inner wall of the impurity removal box 1, so that the filter screen 308 can be quickly and conveniently installed and removed, thereby enabling better filtration of raw materials.

[0033] Furthermore, a spring is fixedly installed between the bottom of the connecting plate 307 and one side of the mounting plate 305. There are two filter screens 308, which are symmetrically distributed on the inner side of the connecting plate 307, so that the filter screens 308 can vibrate up and down better, thereby effectively preventing the filter screens 308 from becoming clogged.

[0034] When impurity removal is required for cement grinding aid raw materials, the operator pours the raw materials into the impurity removal box 1 through the feed hopper located at the top of the box. The raw materials are then filtered through the filter screen 308 installed inside the connecting plate 307. At this time, the motor 301 is started, driving the rotating rod 302 to rotate. The rotation of the rotating rod 302 drives the stirring rod 303 to rotate, which stirs the raw materials, effectively preventing clogging and improving the filtration and impurity removal process. Simultaneously, the rotation of the rotating rod 302 drives the cleaning brush 304 to rotate, cleaning the surface of the filter screen 308 and effectively preventing clogging. When blockage occurs, the auxiliary mechanism 4 can be activated to better adsorb and clean the iron filings in the raw material. It can also squeeze the connecting plate 307 to slide on the guide rod 306. The sliding of the connecting plate 307 compresses the spring and drives the filter screen 308 to move. When there is no contact, the spring force resets it, which vibrates the filter screen 308 and further prevents blockage. When the filter screen 308 needs to be disassembled, the fixing bolt 310 is rotated to move it on the inner wall of the limiting plate 309. The movement of the fixing bolt 310 allows it to be pulled out from the connecting plate 307, thereby releasing the limiting fixation of the filter screen 308. At this time, the filter screen 308 can be disassembled. When installation is required, the above steps are repeated in reverse.

[0035] Example 2:

[0036] Based on Embodiment 1, the auxiliary mechanism 4 includes a magnetic separation roller 401, a belt 402, a rotating rod 403, a cam 404, and a belt 405. The outer wall of the magnetic separation roller 401 is connected to the outer wall of the rotating rod 403 via the belt 402. The outer wall of the rotating rod 403 is connected to the inner wall of the cam 404. The outer wall of the rotating rod 403 is connected to the belt 405.

[0037] In this embodiment, there are two rotating rods 403, which are symmetrically distributed on the inner wall of the impurity removal box 1. There are four cams 404, which are symmetrically distributed on the outer wall of the two rotating rods 403. The two rotating rods 403 are connected by a belt 405, which enables the cams 404 to rotate quickly and conveniently, thereby causing the filter screen 308 to vibrate and filter the raw materials better.

[0038] Furthermore, the bottom of the impurity removal box 1 is connected to the top of the support leg 2, the bottom of the impurity removal box 1 is connected to the top of the motor 301, and the inner wall of the impurity removal box 1 is rotatably connected to both ends of the magnetic separation roller 401.

[0039] When it is necessary to remove impurities from cement grinding aid raw materials, the operator pours the raw materials into the impurity removal box 1 through the feed hopper located at the top of the impurity removal box 1. By activating the impurity removal mechanism 3, the raw materials can be quickly and easily stirred and impurities removed, and the filter screen 308 can be quickly and easily disassembled and assembled. At this time, by activating the magnetic separation roller 401, iron filings in the raw materials can be adsorbed and cleaned. As the magnetic separation roller 401 rotates, it drives the rotating rod 403, which is driven by the belt 402, to rotate. Since the belt 405 enables both rotating rods 403 to rotate simultaneously, the rotation of the rotating rods 403 drives the cam 404 to rotate. The rotation of the cam 404 can squeeze the filter screen 308 to vibrate up and down, thereby further preventing the filter screen 308 from clogging and thus achieving better impurity removal.
