Abstract
Description
Technical Field
[0001] This application relates to the technical field of putty powder production equipment, and in particular to a screening device. Background Technology
[0002] Putty powder is an indispensable base treatment material in building decoration projects, and its importance extends to multiple dimensions such as ensuring building quality, improving living experience, and maintaining environmental protection and health.
[0003] In putty powder production, screening devices use screens to intercept large particles of sand, gravel, iron filings, fibers, and other mechanical impurities in the raw materials, preventing these impurities from causing abnormal gelation reactions or surface defects in the coating. The screening device mainly consists of a base and a screening body mounted on the base. A filter screen is installed inside the screening body, and a discharge pipe is located on the side wall of the screening body. A vibrating motor is also installed at the bottom of the screening body. The continuous vibration of the screening body causes the filtered material to be discharged through the discharge pipe.
[0004] During the production process, to facilitate material discharge, a flexible material discharge component, such as cloth or flexible film, is usually tied to the discharge pipe. The lower end of the discharge component can be placed into a collection bag or tank to facilitate the loading of powder. However, the discharge component is usually connected by means of wire or rope binding, which can easily loosen or fall off during continuous vibration. Utility Model Content

Detailed Implementation
[0033] The present application will be further described in detail below with reference to the accompanying drawings.
[0034] This application discloses a screening device. (Refer to...) Figure 1 The screening device includes a screening shell 1 and a discharge pipe 2 installed on the side wall of the screening shell 1. During the screening process, the screening shell 1 vibrates continuously, and the material in the screening shell 1 can be discharged from the discharge pipe 2 after screening. A discharge component 3 is also installed at the discharge pipe 2, and a connecting assembly 4 is detachably connected to the discharge pipe 2 for the discharge component 3. The discharge component 3 has a through-hole structure at both ends, and the discharge component 3 can be selected from cloth material or flexible polymer material, etc. The powder is discharged from the discharge pipe 2 and discharged downwards along the discharge component 3. The collection container is located at the lower end of the discharge component 3 for receiving the material.
[0035] Reference Figure 1 and Figure 2 A connecting ring 5 is coaxially fixed to the outer wall of the discharge pipe 2. (Combined) Figure 3 The connecting assembly 4 includes a first ring 41 and a second ring 42 sleeved on the outer wall of the discharge pipe 2, and a positioning member 43 connecting the second ring 42 to the connecting ring 5. The first ring 41 and the second ring 42 are located below the connecting ring 5, and the first ring 41 is located in the inner cavity of the second ring 42. The lower inner wall of the first ring 41 is provided with an abutment edge 6, which is used to support the first ring 41. The inner diameter of the first ring 41 is slightly larger than the outer wall of the discharge pipe 2. The upper end of the discharge member 3 passes through the inner cavity of the first ring 41, and is wound between the first ring 41 and the second ring 42, and extends between the abutment edge 6 and the lower end of the first ring 41. The second ring 42 is connected to the connecting ring 5, and the upper end of the first ring 41 abuts against the connecting ring 5, so that the upper end of the discharge member 3 is clamped by the first ring 41 and the second ring 42.
[0036] Reference Figure 3 and Figure 4 The second ring body 42 is provided with multiple extension blocks 7. In this embodiment, there are two extension blocks 7, which are symmetrically arranged along the circumference of the second ring body 42. The extension blocks 7 have through holes 8, and the lower surface of the connecting ring 5 has slots 9 for inserting the extension blocks 7. Figure 5 The side wall of the connecting ring 5 is also provided with a positioning groove 10, which extends radially along the connecting ring 5 and is connected to the slot 9. The positioning member 43 includes a positioning rod 431 inserted into the positioning groove 10. When the extension block 7 is inserted into the slot 9, the positioning rod 431 is inserted into the positioning groove 10 and passes through the through hole 8, thereby preventing the extension block 7 from disengaging from the slot 9.
[0037] The second ring 42 is formed by splicing two semi-circular splice bodies 421, with extension blocks 7 located on the two splice bodies 421 respectively. Abutment strips 11 are fixed to the surfaces of the splice bodies 421 near their ends. When the splice bodies 421 abut to form the second ring 42, the abutment strips 11 abut against each other. The second ring 42 is a spliced structure, making it easier for the upper end of the discharge component 3 to abut against the abutment edge 6 and the first ring 41. An elastic element 152 can be provided on the inner wall of the second ring 42 to better clamp the discharge component 3. A limiting groove (not shown in the figure) is formed on the lower surface of the connecting ring 5. After the abutment strips 11 abut against each other, they can abut against the limiting groove, thereby further improving the stability of the splice body 421 connected to the connecting ring 5. Furthermore, a guide groove 14 is provided on one end face of the splice body 421, and a guide strip 13 is fixed on the other end. When the splice body 421 forms the second ring body 42, the guide strip 13 can be inserted into the adjacent guide groove 14.
[0038] In a further embodiment, refer to Figure 2 and Figure 5 In order to prevent the positioning rod 431 from sliding out of the positioning groove 10, a limiting member 15 is installed on the connecting ring 5. The limiting member 15 is used to reinforce the positioning rod 431 to limit the sliding of the positioning rod 431.
[0039] The limiting member 15 includes a limiting rod 151 that slides through the upper surface of the connecting ring 5 and an elastic member 152 disposed on the outer wall of the limiting rod 151. The elastic member 152 drives the lower end of the limiting rod 151 to extend into the positioning groove 10. The side wall of the positioning rod 431 is provided with a through groove 12. After the positioning rod 431 passes through the through hole 8, the lower end of the limiting rod 151 is inserted into the through groove 12, thereby preventing the positioning rod 431 from sliding further.
[0040] The elastic element 152 is a spring and is sleeved on the outer wall of the limiting rod 151. One end of the spring is connected to the upper end of the limiting rod 151, and the other end is connected to the surface of the connecting ring 5. Under the action of the spring force, the lower end of the limiting rod 151 is inserted into the through groove 12. When it is necessary to pull out the positioning rod 431, the limiting rod 151 can be pulled upward.
[0041] Reference Figure 2The lower end of the discharge component 3 is evenly provided with hooks 16 along the circumference, preferably four. The side wall of the discharge component 3 is provided with hanging rings 17, and four sets of hanging rings 17 are provided, with multiple hanging rings 17 evenly arranged along the length of the discharge component 3 in each set. The hooks 16 can be hooked onto the hanging rings 17, thereby adjusting the overall length of the discharge component 3. Furthermore, a gravity ring 18 is fitted onto the side wall of the discharge component 3. The gravity ring 18 is located at the bent part of the discharge component 3, and the gravity ring 18 ensures that the discharge component 3 is in a vertical state, facilitating material discharge.
[0042] The implementation principle of a screening device according to an embodiment of this application is as follows: the discharge component 3 is clamped and fixed by the first ring 41 and the second ring 42, and the second ring 42 is connected to the connecting ring 5. The installation and disassembly of the second ring 42 are convenient and easy to maintain.
[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
