Description

Technical Field

[0001] This utility model mainly relates to the field of vibrating screen technology, specifically a vibrating screen for the production of polyethylene wax. Background Technology

[0002] Vibrating screens play a crucial role in the production of polyethylene wax. They are mainly used for screening and grading polyethylene wax to remove impurities, control particle size, and ensure product quality. Through the screening action of vibrating screens, polyethylene wax particles that meet the requirements can be obtained to satisfy the needs of subsequent processing or application. Linear vibrating screens are commonly used in industry for screening polyethylene wax. During the operation of vibrating screens, it is often necessary to replace the screen mesh. Existing vibrating screens usually require disassembly of the shell for replacement, which is cumbersome. Furthermore, because the material continuously rolls forward in linear vibrating screens, the utilization rate of the lower screen mesh is low, resulting in material accumulation.

[0003] According to application number CN202322004806.5, a vibrating screen with easily replaceable screen mesh is disclosed, which relates to the field of vibrating screen technology. The screen mesh includes a base, several screen chambers, a top cover, and a set of locking components. A top seat is fixed to the top of the base by several springs. Several screen chambers and the top cover are arranged sequentially above the top seat. Fixed edges are provided at the top and bottom edges of the screen chambers and at the bottom edge of the top cover. A shaft is fixed to the fixed edge of the bottom edge of the screen chamber and the edge of the top seat by hinges. A rotating sleeve is fixed to the fixed edge of the top edge of the screen chamber and the edge of the top cover.

[0004] The aforementioned document, through its design of a sieve chamber and top cover that can be flipped sequentially, provides a larger space for the quick installation and removal of the sieve screens inside the chamber, but it cannot solve the problem of low utilization of the lower sieve screens. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a vibrating screen for the production of polyethylene wax, so as to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A vibrating screen for producing polyethylene wax includes a support frame, a screening frame disposed on top of the support frame, a first screen disposed in the middle of the screening frame, a second screen disposed on top of the first screen, an anti-detachment component disposed at the higher end of the screening frame, vibrating components disposed on both sides of the screening frame, and a driving component disposed in the middle of one side of the screening frame.

[0008] Preferably, the first screen includes two first sliding grooves disposed on both sides inside the screening frame, two first sliding bars disposed on both sides of the first screen, and a first handle disposed at the higher end of the first screen.

[0009] Preferably, the second screen includes two second sliding grooves disposed on both sides inside the screening frame, two second sliding bars disposed on both sides of the second screen, a second handle disposed at the higher end of the second screen, and a reverse inclined groove disposed below the second screen.

[0010] Preferably, the anti-detachment component includes a gear rotatably disposed at one end of the screening frame, two slots with opposite notches on both sides of the gear, a toothed belt plate slidably disposed inside the slots and meshing with the gear, and a knob disposed at one end of the gear.

[0011] Preferably, the screening frame is designed to be inclined, including a first discharge port at the top, a second discharge port in the middle, and a third discharge port at the bottom.

[0012] Preferably, the vibration component includes a circular base disposed around the top of the support, load-bearing blocks disposed on both sides of the screening frame corresponding to the circular base, and a spring connecting the circular base and the load-bearing blocks.

[0013] Preferably, the driving component includes a mounting bracket on one side of the bracket, a drive motor on the top of the mounting bracket, a coupling on the actuating end of the drive motor, and a connecting rod rotatably disposed in the middle of the screening frame and connected to the coupling.

[0014] In summary, this technical solution has the following main advantages:

[0015] In this embodiment, the sliding screen design allows the screen to be easily pulled out from the back of the screening frame or pushed back in, enabling quick screen replacement. By setting anti-detachment components on the back of the screening frame to block the first and second screens, the screen can be released when it needs to be removed, preventing the screen from detaching and causing material leakage during the screening process.

[0016] By setting an anti-sloping chute below the first screen, the material screened from the first screen can slide down to the top of the second screen for screening, instead of the material still being screened from the middle of the second screen. This makes full use of the screening area of ​​the second screen and improves the efficiency of the two-layer screening. Attached Figure Description

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Example

[0026] Please refer to the attached document carefully. Figure 1 , 3 As shown in Figures 5 and 6, a vibrating screen for the production of polyethylene wax includes a support 10, a screening frame 11 at the top of the support 10, a first screen 12 in the middle of the screening frame 11, a second screen 13 at the top of the first screen 12, an anti-detachment component 14 at the higher end of the screening frame 11, vibrating components 15 on both sides of the screening frame 11, and a driving component 16 in the middle of one side of the screening frame 11. The first screen 12 includes two first sliding grooves 121 on both sides inside the screening frame 11, two first sliding bars 122 on both sides of the first screen 12, and a second screen 13 at the lower end of the first screen 12. The first handle 123 at the higher end; the second screen 13 includes two second sliding grooves 131 located on both sides inside the screening frame 11, two second sliding strips 132 located on both sides of the second screen 13, a second handle 133 located at the higher end of the second screen 13, and a reverse inclined groove 134 located below the second screen 13; the anti-detachment component 14 includes a gear 141 that rotates at one end of the screening frame 11, two slots 142 with opposite notches located on both sides of the gear 141, a toothed belt plate 143 that slides inside the slots 142 and meshes with the gear 141, and a knob 144 located at one end of the gear 141.

[0027] It should be noted that the first screen 12 has a smaller aperture, while the second screen 13 has a larger aperture. The first screen 12 and the second screen 13 are tilted at the same angle to the screening frame 11. The top of the anti-sloping groove 134 is fixed to the side wall of the screening frame 11 below the first screen 12, while the bottom is suspended above the top of the second screen 13. The first handle 123 and the second handle 133 are misaligned, and the two toothed belt plates 143 are blocked in the middle of the first handle 123 and the second handle 133 respectively when they are released.

[0028] Furthermore, when it is necessary to replace the screen, turn the knob 144 to make the gear 141 rotate and mesh, driving the toothed belt plates 143 on both sides to retract inward in the slot 142, so as not to block the first screen 12 and the second screen 13.

[0029] Furthermore, by pulling the first handle 123, the two second sliding strips 132 on both sides of the first screen 12 slide out from the two first sliding grooves 121, the first screen 12 can be removed, and after replacing the first screen 12, it can be put back in the same way.

[0030] Furthermore, by pulling the second handle 133, the two first sliding strips 122 on both sides of the second screen 13 slide out from the two second sliding grooves 131, the second screen 13 can be removed, and after replacing the second screen 13, it can be put back in the same way.

[0031] Furthermore, by turning the knob 144 in the opposite direction, the gear 141 rotates and engages, driving the toothed belt plates 143 on both sides to release outward within the slot 142, blocking the middle of the first screen 12 and the second screen 13 to prevent shaking.

[0032] Please refer to the attached document carefully. Figure 1 , 2 As shown in Figure 4, the screening frame 11 is designed with an inclination, including a first discharge port 111 at the top, a second discharge port 112 in the middle, and a third discharge port 113 at the bottom; the vibration component 15 includes a circular base 151 around the top of the support 10, load-bearing blocks 152 on both sides of the screening frame 11 corresponding to the circular base 151, and a spring 153 connecting the circular base 151 and the load-bearing blocks 152; the drive component 16 includes a mounting bracket 161 on one side of the support 10, a drive motor 162 on the top of the mounting bracket 161, a coupling 163 at the actuating end of the drive motor 162, and a connecting rod 164 rotatably located in the middle of the screening frame 11 and connected to the coupling 163.

[0033] It should be noted that the coupling 163 is not connected to the central shaft of the drive motor 162, but is misaligned to a certain extent, which makes the vibration of the screening frame 11 greater when the drive motor 162 rotates. The first discharge port 111, the second discharge port 112 and the third discharge port 113 are misaligned with each other in the vertical direction. The material leaking from the second discharge port 112 is polyethylene wax material with the target pore size, while the pore size leaking from the first discharge port 111 is larger, and the pore size leaking from the third discharge port 113 is smaller.

[0034] Furthermore, the drive motor 162 is started, and the entire screening frame 11 is driven to shake through the coupling 163 and the connecting rod 164. Under the combined action of the round base 151, the load-bearing block 152 and the spring 153, the shaking amplitude reaches a suitable rate.

[0035] Furthermore, the polyethylene wax raw material is poured into the screening frame 11. Under the shaking state, the polyethylene wax raw material is screened out by the second screen 13 to remove the material with larger pore size, and the material with larger pore size leaks out from the first discharge port 111.

[0036] Furthermore, the polyethylene wax raw material from the first screening leaks from the top of the first screen 12 through the anti-sloping trough 134. Under shaking, the material with smaller aperture is screened out, and the qualified material with the correct aperture leaks out from the second discharge port 112; the material with the smaller aperture leaks out from the third discharge port 113.

[0037] The working principle of this utility model is as follows:

[0038] First, when the screen needs to be replaced, turn the knob 144 to rotate the gear 141, which engages the toothed belt plates 143 on both sides, causing them to retract inward within the slot 142, no longer obstructing the first screen 12 and the second screen 13. Pull the first handle 123 to allow the two second sliding strips 132 on both sides of the first screen 12 to slide out from the two first sliding grooves 121, removing the first screen 12. After replacing the first screen 12, it can be put back in the same way. Pull the second handle 133 to allow the two first sliding strips 122 on both sides of the second screen 13 to slide out from the two second sliding grooves 131, removing the second screen 13. After replacing the second screen 13, it can be put back in the same way. Turn the knob 144 in the opposite direction to rotate the gear 141, which engages the toothed belt plates 143 on both sides, causing them to retract inward within the slot 142. Release from inside to outside, blocking the middle of the first screen 12 and the second screen 13 to prevent shaking, start the drive motor 162, and drive the entire screening frame 11 to shake through the coupling 163 and the connecting rod 164. Under the combined action of the round base 151, the bearing block 152 and the spring 153, the shaking amplitude reaches a suitable rate, and the polyethylene wax raw material is poured into the screening frame 11. Under the shaking state, the polyethylene wax raw material is screened out by the second screen 13 to remove the material with larger aperture. The material with larger aperture leaks out from the first discharge port 111. The polyethylene wax raw material screened once leaks out from the anti-sloping trough 134 to the top of the first screen 12. Under the shaking, the material with smaller aperture is screened out. The qualified material with larger aperture leaks out from the second discharge port 112; the material with smaller aperture leaks out from the third discharge port 113.

[0039] The above embodiments are only for illustrating the technical concept of this utility model and should not be used to limit the protection scope of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the protection scope of this utility model.
