Description
Technical Field
[0001] This utility model belongs to the field of molecular sieve sieving technology, and specifically relates to a molecular sieve screening device. Background Technology
[0002] In industrial production, molecular sieves are widely used in chemical, pharmaceutical, and food industries to separate and screen materials of different particle sizes. Through molecular sieve screening, products with higher purity can be obtained. For example, in chemical production, molecular sieve screening can remove impurities during the reaction process, improving the purity and quality of the final product.
[0003] The screen replacement process in traditional molecular sieve screening devices can be complex and time-consuming, impacting production efficiency. Traditional devices may use screws, clamps, or other complex fixing methods to secure the screens. These methods require tools for disassembly and installation, involving numerous steps and increasing the time and labor intensity of screen replacement. Traditional devices may lack a quick screen replacement mechanism, such as a pull-out or quick-locking device, resulting in tedious disassembly and reinstallation work every time a screen is replaced. Traditional devices may only support specific screen sizes; if different sizes of screens are needed, additional adaptation or adjustment work may be required. If the structure of the screen box and screen is not conducive to quick disassembly and installation, such as using a fixing method that is not easy to loosen, then screen replacement will be even more time-consuming.
[0004] To address these issues, a molecular sieve screening device is proposed, which employs a quick-locking device for the screen and an easily removable screen fixing method to simplify the screen replacement process and improve production efficiency. Utility Model Content
[0005] The present invention aims to solve the technical problem that the screen replacement process of molecular sieve screening devices in the prior art may be complex and time-consuming, affecting production efficiency.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A molecular sieve screening device includes a sieve box and a mesh screen. The inner side of the sieve box is provided with a number of support rods arranged symmetrically on both sides and an inverted L-shaped locking block located above each support rod. The mesh screen is pulled out and inserted into the inner side of the sieve box. The mesh screen includes a U-shaped sieve frame and a sieve screen installed on the U-shaped sieve frame.
[0008] The U-shaped screen frame is inserted into the top of the support rod and is limited below the inverted L-shaped locking block. After the two external threaded rods at both ends of the inverted L-shaped locking block pass through the screen box, the U-shaped screen frame is locked and fixed in the L-shaped groove formed by the screen box, the inverted L-shaped locking block and the support rod by the locking nut.
[0009] As preferred, two vibration motors are arranged on one side of the screening box. The two vibration motors can ensure that the screening box vibrates more uniformly, reducing the problem of uneven screening caused by uneven vibration.
[0010] As preferred, four groups of U-shaped mounting blocks are symmetrically arranged on the left and right sides of the screening box, and the bottoms of the U-shaped mounting blocks are fixedly connected with the four supporting columns on the support through damping springs. The damping springs can absorb and buffer the vibration generated by the vibration motor, reducing the influence on the screening box and the overall structure of the device.
[0011] As preferred, the center of the U-shaped mounting block is fixedly connected with the screening box through a reinforcing plate. The reinforcing plate increases the strength of the connection part, making the overall structure of the screening box more solid.
[0012] As preferred, the top of the four supporting columns is fixedly provided with a supporting column inserted into the damping spring but away from the U-shaped mounting block. The arrangement of the supporting column provides an additional support point, increasing the stability of the screening box as a whole.
[0013] As preferred, a guide discharge box is arranged below each screen on the screening box, and the end of the guide discharge box is provided with a discharge nozzle opening downward. The guide discharge box ensures that the screened materials can be discharged according to the predetermined path and direction, reducing the scattering and waste of the materials.
[0014] As preferred, reinforcing webs are further fixedly arranged on the left and right sides of the screening box. The reinforcing webs can enhance the structural strength of the screening box.
[0015] As preferred, a cover plate is buckled to the top of the screening box through a lock, and the cover plate is provided with a feeding hopper located away from the guide discharge box. The arrangement of the cover plate makes feeding more convenient, and the user can directly add materials from the feeding hopper. The cover plate can close the top of the screening box, preventing dust and impurities from entering the inside of the screening box and keeping the screening environment clean.
[0016] Compared with the prior art, the technical effects and advantages of the present application are:
[0017] The molecular sieve screening device, the design of the supporting rod and the inverted L-shaped locking block ensures uniform stress and firm fixation of the screen, avoids deformation and displacement during operation. The pull-out design simplifies the installation and replacement process of the screen, improving work efficiency. The fastening effect of the external thread rod and the locking nut provides strong fixing force, ensuring the stability of the screen during screening.
[0018] The structural strength of the device is significantly enhanced by setting the reinforcing webs on both sides of the screen box, which can withstand greater load and vibration, reduces deformation during vibration, and improves the stability of the screening process. This design not only prolongs the service life of the equipment, but also reduces maintenance costs. The cover plate at the top of the screen box is connected by a lock catch, which facilitates the feeding of materials and ensures the cleanliness of the screening environment and the safety of the operation. The lock catch design facilitates the maintenance of internal components of the screen box, while ensuring that the cover plate is securely fixed during the screening process to prevent accidental opening.
[0019] The design of the guide discharge box and the discharge nozzle ensures that the screened materials can be discharged according to the predetermined path and direction, reducing material scattering and waste, and improving screening efficiency. The design of the discharge nozzle effectively controls the outflow of materials, reducing environmental pollution and interference to operators.
[0020] The two vibration motors provided on one side of the screen box provide uniform vibration, improving screening efficiency and accuracy. The two motors can be controlled separately to adjust the direction and intensity of the screen box vibration, adapting to different screening requirements. The U-shaped mounting blocks symmetrically arranged in front and back ensure the balance of the screen box, making the screening process more stable. BRIEF DESCRIPTION OF DRAWINGS

[0028] The following will be described in detail with reference to the drawings of the embodiments of the present application. Figures 1-5 The present application will be further described in detail,
[0029] The embodiment of the present application discloses a molecular sieve screening device, which comprises a sieve box 1 and a mesh sieve 4, and reinforcing webs 19 are further fixedly arranged on the left and right side surfaces of the sieve box 1. The reinforcing webs 19 can enhance the structural strength of the sieve box 1, so that the sieve box 1 can bear greater load and vibration. The reinforcing webs 19 help to reduce the deformation of the sieve box 1 in the vibration process, and improve the stability of the screening process. By strengthening the structure of the sieve box 1, the service life of the device can be prolonged, and the maintenance cost can be reduced.
[0030] The top of the sieve box 1 is buckled with a cover plate 21 through a lock buckle 20, the cover plate 21 is provided with a feeding hopper 22, and the feeding hopper 22 is located away from one end of the guide discharge box 17. The cover plate 21 is arranged to make feeding more convenient, and users can directly add materials from the feeding hopper 22. The cover plate 21 can close the top of the sieve box 1 to prevent dust and impurities from entering the inside of the sieve box 1, and keep the screening environment clean. The lock buckle 20 design of the cover plate 21 can ensure that the cover plate 21 is firmly fixed on the sieve box 1 during the screening process, prevent accidental opening, and improve the operation safety. The lock buckle 20 design also facilitates the opening of the cover plate 21 to overhaul the internal components of the sieve box 1. The position design of the feeding hopper 22 helps to uniformly distribute the materials, thereby improving the screening efficiency and effect.
[0031] A plurality of left-right symmetrical support rods 2 and inverted L-shaped locking blocks 3 located above each support rod 2 are vertically and equidistantly arranged on the inner side surface of the sieve box 1; the mesh sieve 4 is pullably inserted into the inner side of the sieve box 1, and the mesh sieve 4 comprises a U-shaped sieve frame 5 and a sieve screen 6 mounted on the U-shaped sieve frame 5;
[0032] The U-shaped sieve frame 5 is inserted into the top of the support rod 2 and limited below the inverted L-shaped locking block 3, two external thread rods 7 at both ends of the inverted L-shaped locking block 3 pass through the sieve box 1, and the U-shaped sieve frame 5 is locked and fixed in the L-shaped notch 9 surrounded by the sieve box 1, the inverted L-shaped locking block 3 and the support rod 2 through a locking nut 8.
[0033] The device is used for screening molecular sieves, the sieve box 1 is the main part of the device, and the mesh sieve 4 is part of the screened molecular sieves. The separation design of the sieve box 1 and the mesh sieve 4 facilitates the replacement of different specifications of the sieve screen 6, and improves the applicability and flexibility of the device. The mesh sieve 4 is horizontally inserted into the sieve box 1 to form a straight vibrating screen.
[0034] The design of the support rod 2 is used to support the screen 4, and the symmetrical arrangement ensures uniform stress on the screen 6. The uniformly distributed support rod 2 improves the stability of the screen 4, avoiding deformation of the screen 4 during operation. The inverted L-shaped locking block 3 is located above the support rod 2, used to fix the position of the screen 4. The inverted L-shaped design increases the stability of the locking block, so that the screen 4 can be more firmly fixed. The screen 6 is connected to the screen box 1 through the U-shaped screen frame 5, and the pull-out design facilitates the installation and replacement of the screen 6. The pull-out design simplifies the installation process of the screen 6, improving work efficiency. The U-shaped screen frame 5 is inserted into the top of the support rod 2 and is limited below the inverted L-shaped locking block 3, ensuring the accuracy of the position of the screen 6. Ensuring the accurate position of the screen 6 avoids displacement of the screen 6 during screening. The screen 6 is fixed in the L-shaped slot 9 through the fastening action of the external thread rod 7 and the locking nut 8. This locking method provides strong fixing force, ensuring the stability of the screen 6 during screening, while facilitating quick assembly and disassembly and replacement of the screen 6.
[0035] Two vibration motors 10 are provided on one side of the screen box 1.

Two vibration motors 10 can ensure that the vibration of the screen box 1 is more uniform, reducing the problem of uneven screening caused by uneven vibration. The two motors can be controlled separately to adjust the direction and intensity of the vibration of the screen box 1, adapting to different screening requirements.
[0036] Four groups of U-shaped mounting blocks 11 are symmetrically arranged on the left and right sides of the screen box 1, and the center of the U-shaped mounting block 11 is fixedly connected to the screen box 1 through the reinforcing plate 15.
