[0008] The top of the feeding hopper can be connected to a bucket-shaped feeding trough, which makes the upper opening larger, improves the convenience of feeding, and reduces overflow.

[0009] The bottom of the discharge cylinder can be connected to a sealing assembly. The sealing assembly includes a mounting plate, with bolt holes on both the mounting plate and the bottom of the discharge cylinder.

A fixing groove is provided on the discharge cylinder, and both the fixing block and the fixing groove have limit holes. Locking pins are inserted into the limit holes to secure the baffle. By installing a sealing assembly at the bottom of the discharge cylinder, the discharge cylinder can be sealed during sieving and opened after sieving for centralized material discharge, achieving the effect of quantitatively collecting raw materials.

[0010] Furthermore, an inner cavity is provided on the wall of the sieve box at the upper end of the impurity outlet. A sealing plate is slidably installed in the inner cavity. A support rod is connected to the sealing plate. A drive structure for driving the sealing plate to move up and down is connected to the support rod.

[0011] Furthermore, the drive structure includes an electric telescopic rod, the telescopic end of which is connected to the support rod of the sealing plate.

[0012] Furthermore, a slot is provided at the bottom of the inner cavity, and a plug is connected to the sealing plate to mate with the slot.

[0013] Furthermore, a limiting structure is connected between the inner cavity wall and the support rod.

[0014] Furthermore, the limiting structure includes a limiting groove disposed on the box wall of the inner cavity, and a limiting block is connected to the support rod, the limiting block moving up and down within the limiting groove.

[0016] Furthermore, the power structure includes a transmission wheel one connected to the rotating shaft, a drive motor connected to the top of the sieve box, a transmission wheel two connected to the output shaft of the drive motor, and the transmission wheel one and the transmission wheel two connected by a transmission belt.

[0017] Furthermore, an annular groove is provided inside the ring, and an annular rotating block that is rotatably connected to the annular groove is provided on the rotating shaft.

[0018] Secondly, this application provides a self-leveling mortar production apparatus, including the aforementioned impurity removal structure.

[0019] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0020] (1) By connecting a sealing structure at the impurity outlet, this utility model can prevent the raw materials and impurities from being discharged together from the impurity outlet during the screening process, thus avoiding the waste of raw materials. At the same time, by setting the screen to a cone structure, the area of ​​the screen is increased and the screening efficiency is improved.

[0021] (2) By connecting the limiting structure between the inner wall of the box and the support rod, it can be ensured that the sealing plate always moves within the inner cavity, thus preventing the sealing plate from detaching from the inner cavity.

[0040] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, a joint, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0041] Example 1

[0042] like Figures 1-5 As shown, this embodiment provides a purification structure for self-leveling mortar production, including a sieve box 02. A feed cylinder 06 is connected to the top of the sieve box 02, and a discharge cylinder 08 is provided at the bottom. A conical sieve screen 07 is installed inside the sieve box 02. The lower end of the conical sieve screen 07 is connected to the inner wall of the sieve box 02, and an impurity outlet 03 is provided on the wall of the sieve box 02. A receiving bucket 01 is connected to the impurity outlet 03, and a sealing structure is connected to the impurity outlet 03.

[0043] Specifically, the screening box 02 above the impurity outlet 03 has an inner cavity on its wall. A sealing plate 09 is slidably installed inside the inner cavity, and a support rod 05 is connected to the sealing plate 09. A drive structure 04 is connected to the support rod 05 to drive the sealing plate 09 to move up and down. Slide grooves are provided on both sides of the inner cavity, and sliders installed in the slide grooves are connected to the sealing plate 09. By driving the support rod 05 up and down through the drive structure 04, the sliders can move within the slide grooves, thereby moving the sealing plate 09.

[0044] Specifically, the drive structure 04 includes an electric telescopic rod, the telescopic end of which is connected to the support rod 05 of the sealing plate 09. The sealing plate 09 is moved up and down by extending and shortening the electric telescopic rod. When it is necessary to block the impurity outlet 03, the electric telescopic rod shortens, causing the sealing plate 09 to move down to the impurity outlet 03; when it is necessary to discharge impurities on the cone screen 07 from the impurity outlet 03, the electric telescopic rod extends, causing the sealing plate 09 to move up.

[0045] Specifically, a slot 10 is provided at the bottom of the inner cavity, and a plug 11 that mates with the slot 10 is connected to the sealing plate 09. When the sealing plate 09 moves down to the bottom, the plug 11 on the sealing plate 09 is inserted into the slot 10.

[0046] When using this impurity removal structure to remove impurities from the raw materials used in the production of self-leveling mortar, the sealing plate 09 is first moved down to the impurity outlet 03 by shortening the electric telescopic rod, sealing the impurity outlet 03. Then, the raw material to be removed is poured into the feed cylinder 06 and falls onto the conical screen 07 in the sieve box 02 through the feed cylinder 06. After being sieved by the conical screen 07, the raw material falls to the bottom of the sieve box 02 and is discharged from the discharge cylinder 08 at the bottom of the sieve box 02. After a certain amount of raw material has been sieved, the feeding is stopped, and the sealing plate 09 is moved up by extending the electric telescopic rod, opening the impurity outlet 03. At this time, the impurities that have been sieved can be discharged from the impurity outlet 03 into the receiving bucket 01. Since there is no raw material on the conical screen 07, there is no waste of raw material. In addition, the bottom of the receiving bucket 01 is provided with a discharge port, and the received impurities can be discharged from the discharge port at the bottom of the receiving bucket 01.

[0047] In this embodiment, the impurity removal structure for self-leveling mortar production can avoid the waste of raw materials by connecting a sealing structure at the impurity outlet 03 during the screening process, thus preventing the raw materials and impurities from being discharged together from the impurity outlet 03. At the same time, setting the screen to a conical structure increases the screen area and improves screening efficiency.

[0048] Example 2

[0049] Based on Example 1, such as Figure 6 and Figure 7 As shown, this embodiment provides a purification structure for self-leveling mortar production. Unlike Embodiment 1, this embodiment features a limiting structure connecting the inner cavity wall to the support rod 05. The limiting structure includes a limiting groove 12 on the inner cavity wall and a limiting block 13 connected to the support rod 05. The limiting block 13 moves up and down within the limiting groove 12. Other structural features are the same as in Embodiment 1.

[0050] Compared with Embodiment 1, the advantage of this embodiment is that by connecting a limiting structure between the inner cavity wall and the support rod 05, it can be ensured that the sealing plate 09 always moves within the inner cavity, thus preventing the sealing plate 09 from detaching from the inner cavity.

[0051] Example 3

[0052] Based on Example 2, such as Figure 8As shown, this embodiment provides a purification structure for self-leveling mortar production. Unlike Embodiment 2, this embodiment has a common rotating shaft 18 installed inside the feed cylinder 06 and discharge cylinder 08. Spiral blades 20 are connected to the rotating shaft 18 inside both the feed cylinder 06 and discharge cylinder 08. A power structure for driving the rotating shaft is connected to the rotating shaft 18. A ring 19 is connected to the top of the conical screen 07, and the rotating shaft 18 is rotatably connected within the ring 19. The power structure includes a transmission wheel 14 connected to the rotating shaft 18, a drive motor 17 connected to the top of the sieve box 02, and a transmission wheel 16 connected to the output shaft of the drive motor 17. The transmission wheel 14 and the transmission wheel 16 are connected by a transmission belt 15. Other structural features are the same as in Embodiment 2.

[0053] When using this power structure, the drive motor 17 is turned on, and the power of the drive motor 17 drives the transmission wheel 16 to rotate. The transmission wheel 16 drives the power transmission belt 15 to drive the transmission wheel 14, causing the transmission wheel 14 to rotate, which in turn causes the rotating shaft 18 to rotate, thereby causing the spiral blade 20 connected to the rotating shaft 18 to rotate, thus realizing the conveying of raw materials.

[0054] Compared with Embodiment 2, the advantages of this embodiment are as follows: connecting the rotating shaft 18 with the spiral blade 20 inside the feed cylinder 06 is to improve the feeding efficiency, and connecting the rotating shaft 18 with the spiral blade 20 inside the discharge cylinder 08 is to improve the discharge efficiency. Furthermore, the fact that the feed cylinder 06 and the discharge cylinder 08 share a single rotating shaft 18 can reduce the number of drive motors 17 installed, thereby reducing the manufacturing cost of the equipment. In addition, since the rotating shaft 18 passes through the ring 19 of the conical screen 07, it can generate a certain vibration effect during rotation, causing the conical screen 07 to vibrate, which further improves the screening efficiency.

[0055] Example 4

[0056] Based on Example 3, such as Figure 9 and Figure 10 As shown, this embodiment provides a purification structure for self-leveling mortar production. Unlike embodiment 3, this embodiment has an annular groove 22 inside the ring 19, and an annular rotating block 21 rotatably connected to the annular groove 22 on the rotating shaft 18. The other structures are exactly the same as in embodiment 3.

[0057] Compared with Embodiment 3, the advantage of this embodiment is that by setting an annular groove 22 in the ring 19 of the conical screen 07 and setting an annular rotating block 21 on the rotating shaft 18, the rotation of the rotating shaft 18 can be made more stable on the one hand, and the rotating shaft 18 can have a certain contact with the conical screen 07 on the other hand, thereby further improving the vibration effect of the conical screen 07 during the screening and impurity removal process, improving the screening efficiency, and eliminating the need to install a vibrator, further reducing the manufacturing cost of the equipment.

[0058] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
