Description

Technical Field

[0001] The utility model relates to the technical field of putty powder processing, in particular to an impurity removing device for putty powder processing. Background Art

[0002] Putty powder is an important material for wall decoration. Its purity is directly related to the smoothness and aesthetics of the coating. During the production and processing of putty powder, removing impurities is a key step in ensuring product quality.

[0003] After searching, the Chinese utility model patent with application number 202321536267.3 is an impurity removal device for putty powder processing. Personnel can inject the putty powder that needs to be processed and removed into the shell through the feed pipe, so that the putty powder enters the shell and falls on the screen for limiting. Then the personnel can turn on the vibration motor to drive the screen for vibration screening, so that the impurities left on the screen are moved to the waste pipe through vibration for waste discharge, and the screened putty powder falls after screening through the screen. The personnel can open the valve on the discharge pipe to discharge the material, thereby meeting the requirements of putty powder impurity removal.

[0004] In response to the above-mentioned prior art, the inventor believes that putty powder particles come in different sizes. Although the system is equipped with a vibration motor to optimize screening efficiency, practice has shown that when some putty powder particles happen to be embedded in the fine mesh of the screen due to factors such as size, shape or humidity, and the surface of the screen is continuously covered with putty powder rolling down and covering the surface of the screen, even if the vibration motor is operating at full capacity, the vibration force it generates is often difficult to effectively and thoroughly shake off these stubborn particles from the mesh. Utility Model Content

[0005] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides an impurity removal device for putty powder processing to solve the above problems.

[0006] In order to achieve the above-mentioned purpose, the utility model provides an impurity removal device for putty powder processing, comprising a box body, wherein a feeding hopper is provided at the upper end of the box body.

[0007] Two vertically arranged partitions are fixed inside the box, an impurity discharge channel is formed between the two partitions, and two sieve plates are provided on the upper ends of the two partitions, one end of the sieve plate is rotatably connected to the upper end of the partition, and the other end of the sieve plate is movably overlapped with the inner wall of the box;

[0008] A stopper is fixed to the inner wall of the box, and the screen plate collides with the stopper when rotating;

[0009] The lower end of the feeding hopper is connected with a Y-shaped tube, the two discharge ports of the Y-shaped tube are conveniently facing the surfaces of the two sieve plates, and an electric valve is installed on the discharge port of the Y-shaped tube.

[0010] Preferably, a crushing device is provided at the lower end of the impurity discharge channel.

[0011] Preferably, the pulverizing device includes a grinding chamber fixed at the lower end of the impurity discharge channel and a grinding roller rotatably installed in the grinding chamber.

[0012] Preferably, the box body is equipped with a rotating mechanism for driving the sieve plate to rotate.

[0013] Preferably, the two sieve plates are rotatably connected to the upper ends of the two partitions via two rotating shafts, and the rotating mechanism is a first motor fixed to the outer wall of the box body for driving the rotating shaft to rotate.

[0014] Preferably, the box is equipped with a second motor for driving the grinding roller to rotate.

[0015] Preferably, a vibrator is installed on the lower surface of the sieve plate.

[0016] Preferably, a support block is fixed to the inner wall of the box body, and the movable end of the sieve plate overlaps the surface of the support block.

[0017] Preferably, the box body is provided with an observation window.

[0018] Compared with the prior art, the present invention has the following benefits:

[0019] 1) By introducing two rotatable screen plates and combining them with a motor-driven collision mechanism with a stopper, this new design effectively solves the problem of putty powder particles becoming lodged in the screen mesh due to factors such as size, shape, or moisture. This design not only reduces interruptions in the screening process but also significantly improves screening efficiency and continuity.

[0020] 2) The Y-shaped tube and electric valve equipped in the utility model device allow a single sieve plate to be cleaned without stopping the machine. By closing the electric valve corresponding to the discharge port, the coverage of putty powder on the surface of the sieve plate is reduced, thereby enhancing the collision cleaning effect.

[0021] 3) The utility model integrates a crushing device at the bottom of the impurity discharge channel, which can further process the large-particle putty powder screened out. Through fine grinding in the grinding chamber and grinding roller, the large particles are converted into reusable fine powder, reducing waste generation and achieving maximum resource utilization.

[0028] The following is combined with Figure 1-4 The specific implementation methods of the present utility model are further described in detail.

[0029] like Figure 1-4 As shown, the utility model is an impurity removal device for putty powder processing, comprising a box body 1 , and a feeding hopper 2 for adding putty powder into the box body 1 is provided at the upper end of the box body 1 .

[0030] like Figure 1 and Figure 3 As shown, two vertically arranged partitions 3 are fixed inside the box 1, and an impurity discharge channel 101 is formed between the two partitions 3. Two powder bins 102 are formed on both sides of the outside of the two partitions 3. Two sieve plates 5 for screening putty powder are provided at the upper ends of the two partitions 3. When no blockage occurs, the two sieve plates 5 work simultaneously, so that the putty powder that needs to be removed from the impurities is added to the box 1 through the feeding hopper 2 and directly falls onto the surface of the two sieve plates 5. When rolling downward through the inclined surfaces of the two sieve plates 5, the putty powder that meets the particle size directly passes through the mesh of the sieve plate 5 and falls into the powder bin 102 at the bottom of the box 1, while the large putty powder that does not meet the large particle size rolls through the inclined surfaces of the sieve plates 5 into the impurity discharge channel 101.

[0031] The sieve plate 5 is prone to blockage when working. In order to prevent this problem from occurring, one end of the sieve plate 5 is rotatably connected to the upper end of the partition 3, and the other end of the sieve plate 5 is movably overlapped on the inner wall of the box body 1. A stopper 10 is fixed to the inner wall of the box body 1. The sieve plate 5 collides with the stopper 10 when it rotates. It can be understood that when one of the sieve plates 5 is blocked, the sieve plate 5 is rotated to cause the sieve plate 5 to collide with the stopper 10, so that the debris stuck in the mesh can be shaken off. The shaken-off debris automatically enters the impurity discharge channel 101 and is collected. Its principle is similar to: when we use a rice washing basket to wash rice, the rice is easily stuck in the mesh of the basket. We can grab the basket with one hand and collide the basket with the other hand. During the collision, the rice is easily shaken off from the mesh.

[0032] Furthermore, the lower end of the feeding hopper 2 is connected to a Y-shaped tube 6, and the two discharge ports of the Y-shaped tube 6 are conveniently facing the surfaces of the two sieve plates 5, and an electric valve 7 is installed on the discharge port of the Y-shaped tube 6. When one of the sieve plates 5 needs to be cleaned, the electric valve 7 corresponding to the discharge port of the sieve plate 5 can be closed. In this way, the surface of the sieve plate 5 is no longer covered with putty powder, so that when the sieve plate 5 collides with the block 10, the putty powder stuck in the mesh can be better vibrated out.

[0033] Furthermore, a crushing device is provided at the lower end of the impurity discharge channel 101, which can further crush the large-particle putty powder that has been screened out. The crushed putty powder can be manually added and sent to the feeding hopper 2 again, and screened for the second time through the sieve plate 5. Of course, a common elevator can also be used to send the crushed putty powder back to the feeding hopper 2, which will not be explained in detail here.

[0034] In some embodiments, the crushing device includes a grinding chamber 13 fixed at the lower end of the impurity discharge channel 101 and a grinding roller 14 rotatably installed in the grinding chamber 13. The upper and lower ends of the grinding chamber 13 are both open, and there is a very small grinding gap between the inner wall of the grinding chamber 13 and the side of the grinding roller 14. Large particles of putty powder can be ground when passing through the grinding roller 14.

[0035] The box body 1 is equipped with a rotating mechanism for driving the sieve plate 5 to rotate.

[0036] The two sieve plates 5 are rotatably connected to the upper ends of the two partition plates 3 via two rotating shafts 4 . The rotating mechanism is a first motor 9 fixed to the outer wall of the box body 1 for driving the rotating shafts 4 to rotate.

[0037] The box body 1 is equipped with a second motor 15 for driving the grinding roller 14 to rotate.

[0038] A vibrator 11 is installed on the lower surface of the sieve plate 5, which is used to drive the sieve plate 5 to vibrate at high frequency and accelerate the screening of the putty powder. As mentioned above, this vibration does not have a good dredging effect on the putty powder stuck in the mesh, especially when the surface of the sieve plate 5 is still covered with putty powder. The putty powder stuck in the mesh is even more difficult to escape from the mesh. It is for this reason that the above-mentioned method is implemented: first close the electric valve 7 corresponding to the discharge port of the sieve plate 5 so that the surface of the sieve plate 5 is no longer covered with putty powder, and then collide the sieve plate 5 with the block 10 to vibrate the putty powder stuck in the mesh of the sieve plate 5.

[0039] A support block 12 is fixed to the inner wall of the box body 1 , and the movable end of the sieve plate 5 is overlapped on the surface of the support block 12 .

[0040] The box body 1 is provided with an observation window 16, which is convenient for observing the screening situation inside the box body 1, thereby facilitating the staff to make timely responses.

[0041] A dust collector 8 is installed on the side of the box body 1 to absorb dust inside the box body 1.

[0042] The principle of the impurity removal device for putty powder processing of the present invention is as follows: using two rotatable sieve plates 5, without stopping the machine, the sieve plates 5 are driven to rotate by the first motor 9 and collide with the block 10, so that the impact force generated will shake off the putty powder particles stuck in the sieve holes, thereby cleaning the sieve holes and avoiding blockage. At the same time, combined with the high-frequency vibration of the vibrator 11, the screening process of the putty powder is accelerated and the screening efficiency is improved. In addition, a crushing device is also provided at the lower end of the impurity discharge channel 101 to crush large particles of impurities. The crushed putty powder can be manually added and sent to the feeding hopper 2 again, and screened twice through the sieve plate 5 to ensure the purity of the final product.

[0043] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
