Description

Technical Field

[0001] This utility model belongs to the technical field of desiccant filter conduit devices, specifically a device for screening desiccants of different sizes. Background Technology

[0002] During production and application, desiccants generally need to be screened according to different sizes to meet various usage requirements. For example, in pharmaceutical packaging and moisture protection of electronic equipment, there are strict requirements on the particle size of desiccants; particles that are too large or too small may affect their moisture absorption effect or safety. Therefore, classifying desiccants by size through screening is crucial to ensuring their performance stability and application effectiveness.

[0003] A search revealed that Chinese patent CN2024212706861 discloses "A device for rapidly screening desiccants of different sizes using a filter conduit". By using a drive motor, an electric push rod, a spiral feeder, and a screening screen, it achieves more efficient screening of desiccants of different specifications, improving efficiency and solving the problem that most existing desiccant filter conduit devices do not have the function of screening desiccants of different specifications, often requiring manual screening, which greatly affects the user's work efficiency.

[0004] However, the device uses an auger conveyor, which relies on spiral blades to push the raw material. During the conveying process, the desiccant is prone to accumulate on the filter screen, causing the filter screen to become clogged and affecting the screening effect. In addition, without vibration assistance, some desiccant particles cannot come into contact with the filter screen, resulting in uneven screening. Summary of the Invention

[0005] The purpose of this invention is to provide a filter conduit device for screening desiccants of different sizes. This device can screen desiccants of different particle sizes while performing multi-stage screening, giving it the advantages of high screening efficiency, high precision, anti-clogging, strong stability, and wide applicability.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A device for screening desiccant filter conduits of different sizes is provided, comprising a screening chamber, a double-headed motor installed at the bottom of the inner wall of the screening chamber, a drive shaft fixedly connected to the output end of the double-headed motor, a turntable fixedly connected to one end of the drive shaft, pulleys installed on the outer wall of the turntable, a vibration chamber disposed inside the screening chamber, connecting plates fixedly connected to both sides of the bottom of the vibration chamber, a linkage groove formed inside the connecting plate, the pulleys located inside the linkage groove, and the two sides of the vibration chamber... The outer wall is fixedly connected to a limiting block, and there are multiple limiting blocks. The bottom of each limiting block is fixedly connected to a spring. Limiting grooves are opened on both sides of the outer wall of the screening chamber. The limiting block is located inside the limiting groove. The bottom of the spring is fixedly connected to the bottom of the inner wall of the limiting groove. A limiting rod is fixedly connected to the inner wall of the limiting groove. The limiting rod passes through the limiting block. The vibration box is equipped with a fixing plate, and there are multiple fixing plates. The fixing plates are placed at an angle, with the left end lower than the right end. The two upper fixing plates are both provided with hollow grooves inside.

[0007] Optionally, a shaped block is fixedly connected to the inner wall of the vibration box, and a guide groove is opened inside the shaped block. The right outer wall of the shaped block is fixedly connected to multiple fixed plates. A guide tube is fixedly connected to the bottom of the shaped block, and there are multiple guide tubes. The multiple guide tubes correspond to the multiple guide grooves respectively. A positioning block is fixedly connected to the bottom of the inner wall of the screening chamber, and the bottom of the multiple guide tubes is located inside the positioning block.

[0008] Optionally, a support plate is fixedly connected to the bottom of the inner wall of the screening chamber, and there are two support plates, with the drive shaft passing through the support plate.

[0009] Optionally, the bottom of the screening chamber is fixedly connected to a discharge pipe, and there are multiple discharge pipes, the positions of which correspond to the positions of multiple guide pipes.

[0010] Optionally, the bottom of the screening chamber is fixedly connected to a support leg, and there are multiple support legs, with a base plate fixedly connected to the bottom of the multiple support legs.

[0011] Optionally, a collection box is fixedly connected to the top of the base plate, and a collection compartment is provided inside the collection box, and there are multiple collection compartments.

[0012] Optionally, the bottom of the base plate is provided with a shock-absorbing pad, and the outer wall of the shock-absorbing pad is fixedly connected with a fixing foot, and the number of fixing feet is multiple.

[0013] Optionally, a feed inlet is provided at the top of the screening chamber, the feed inlet is located on the top right side of the screening chamber, and a baffle is provided on the top right side of the vibration box.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model is equipped with a dual-head motor, drive shaft, turntable, pulley, vibration box, connecting plate, limiting block, spring, limiting groove, limiting rod, fixing plate, irregular block, guide tube, and positioning block. After the dual-head motor is started, it drives the drive shaft to rotate, and the turntable at the end of the drive shaft rotates accordingly. The pulley set on the outer wall of the turntable is embedded in the linkage groove of the connecting plate, converting the rotational motion into a precise vertical reciprocating linear motion. The connecting plate is rigidly connected to the vibration box, so that the vibration box generates stable and controllable vertical vibration in the screening chamber. The limiting blocks symmetrically arranged on both sides of the vibration box slide precisely along the limiting rod in the limiting groove. With the elastic deformation of the spring, it not only ensures the accuracy of the vibration trajectory, but also effectively absorbs the vibration impact, realizing efficient and precise automated grading and screening of desiccant, avoiding the influence of auger conveying on the screening effect. At the same time, with the help of vibration, the screening is more uniform.

[0015] 2. This utility model includes a discharge pipe, support legs, a base plate, a collection box, a collection container, shock-absorbing pads, fixing feet, a feed inlet, and baffles. The desiccant raw material enters the vibrating chamber evenly through the feed inlet. Guided by the baffles, the raw material makes full contact with multiple layers of fixing plates during vibration. The perforated grooves on the upper fixing plate are larger than those on the middle fixing plate, thus achieving multi-level precise grading of the raw material. The special geometric shape of the irregularly shaped blocks, combined with the guide grooves (which are funnel-shaped), ensures that the graded raw material can quickly and orderly enter the corresponding guide tubes. The precise fit between the guide tubes and the positioning blocks ensures the stability of the raw material transport. Finally, desiccant raw materials of different particle sizes accurately fall into the corresponding collection boxes within the collection box through multiple discharge pipes. This utility model achieves efficient, precise, and automated grading of desiccant raw materials through the combination of mechanical vibration and precision screening. Attached Figure Description

The inner wall bottom of the vibrating box 6 is fixedly connected to the limiting groove 11, and the inner wall of the limiting groove 11 is fixedly connected to the limiting rod 12, which passes through the limiting block 9. The vibrating box 6 is provided with a fixing plate 13, and there are multiple fixing plates 13. The fixing plates 13 are placed at an angle, with the left end lower than the right end. The two upper fixing plates 13 are provided with hollow grooves. The inner wall of the vibrating box 6 is fixedly connected to a shaped block 14, and the shaped block 14 is provided with a guide groove 15.
