Description

Technical Field

[0001] This utility model relates to the field of screening equipment technology, and in particular to a detachable screening component. Background Technology

[0002] In many production fields such as chemical, food, and pharmaceutical industries, screening equipment is an indispensable material handling device. The core component of screening equipment is the screen mesh, and different production processes require screen meshes of different mesh sizes. However, traditional screen mesh assemblies are usually fixed by pressure plates, clamps, and multiple bolts. This fixing method has obvious drawbacks: First, the disassembly and assembly process is cumbersome, requiring the loosening or tightening of multiple bolts one by one, consuming a lot of time and manpower, and seriously affecting production efficiency; second, in the high-frequency vibration working environment, the bolts are prone to loosening, resulting in the screen mesh not being firmly fixed, affecting the screening effect, and even damaging the equipment; third, the seal between the screen mesh and the screen frame usually relies on an independent sealing ring, which is complicated to install and the sealing ring is prone to aging and failure, causing material leakage and cross-contamination.

[0003] Therefore, this application provides a detachable screening assembly to meet the requirements. Utility Model Content

[0004] The purpose of this application is to provide a detachable screening component, which aims to solve the technical problems of complex disassembly and assembly, unreliable fixing, poor sealing effect and inconvenient operation of screening components in the prior art.

[0005] To achieve the above objectives, this application provides the following technical solution: a detachable screening assembly, including a screen frame assembly, the inner wall of which is provided with a first threaded structure; a screen mesh assembly, detachably installed inside the screen frame assembly, the outer wall of which is provided with a second threaded structure that mates with the first threaded structure; and a connecting rod, the screen frame being provided with a mounting part for detachably installing the connecting rod, the connecting rod being used to drive the screen mesh assembly to rotate, so as to achieve threaded connection or separation between the screen mesh assembly and the screen frame assembly.

[0006] Preferably, the top of the screen assembly is also provided with an integrally formed flexible ring plate. When the screen assembly is installed in the screen frame assembly, the flexible ring plate elastically abuts against the inner wall of the frame, playing a role in sealing and radial fastening.

[0007] Preferably, the flexible ring plate is folded outward and upward along its radial direction to generate a radial component force that presses the mesh frame against the frame body while providing a seal.

[0008] Preferably, the mounting part is at least one threaded clamp; the end of the connecting rod is provided with a threaded section, and a threaded sleeve is threadedly connected to the threaded section; by rotating the threaded sleeve, the threaded sleeve can be simultaneously connected to or separated from the connecting rod and the threaded clamp.

[0009] Preferably, the screen frame assembly is further provided with a mounting plate for fixing it to an external device, and the mounting plate has mounting holes to improve the versatility and convenience of installation.

[0010] Preferably, there are two threaded clips, symmetrically arranged on the upper edge of the mesh frame, so that the force applied after the connecting rod is installed is more balanced and stable.

[0011] Preferably, the first thread structure is a thread tooth, and the second thread structure is a thread groove. This structure is simple to implement and has reliable meshing.

[0012] In summary, the technical effects and advantages of this utility model are as follows: In this invention, a threaded connection replaces the traditional fixing method, and a detachable special connecting rod makes the installation and removal of the screen as simple and quick as tightening a screw, greatly improving work efficiency.

[0013] In this invention, the threaded connection has excellent self-locking properties, and combined with the radial clamping force provided by the flexible ring plate, it ensures that the screen remains stable and does not loosen when the equipment vibrates.

[0014] In this invention, the innovative flexible ring plate design combines sealing and fastening functions into one, simplifying the structure while ensuring an effective seal between the screen frame and the screen mesh, preventing material leakage. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0019] refer to Figure 1-5 The detachable screening assembly shown is characterized by the ability to quickly install and remove the screen assembly 20 and the screen frame assembly 10 via a detachable connecting rod 30.

[0020] In one embodiment of this invention, the screen frame assembly 10 serves as the base of the entire assembly and is mainly composed of a circular frame 11. To facilitate connection with the screen assembly 20, internal threads, i.e., thread teeth 13, are machined onto the inner wall of the frame 11. To stably fix this screening assembly to an external screening machine (not shown in the diagram), at least one mounting plate 12 is integrally formed or welded onto the outer wall of the frame 11. The mounting plate 12 has mounting holes 14 for easy bolt passage.

[0021] In one embodiment of this invention, the screen assembly 20 is the core component for performing the material screening function. The screen assembly 20 includes a frame 21 serving as a skeleton, with a filter screen 25 of a specific mesh size securely connected to the bottom of the frame 21. To achieve a threaded fit with the screen frame assembly 10, the outer wall of the frame 21 is machined with external threads matching the thread teeth 13, i.e., threaded grooves 23. The top of the frame 21 extends upwards integrally and folds outwards, forming a flexible ring plate 22. The outward-folding structure of this flexible ring plate 22 allows it to fit tightly against the inner wall of the frame 11 after installation, serving a dual function of sealing and fastening. To facilitate the operator's rotational installation of the screen assembly 20, a mounting portion for temporarily mounting the connecting rod 30 is specially provided on the upper outer wall of the frame 21. In this embodiment, this mounting portion specifically consists of two symmetrically distributed threaded locking blocks 24.

[0022] In one embodiment of this invention, the connecting rod 30 is an independent, detachable operating tool, the main body of which is a long rod that is easy to hold. External threaded sections are machined at both ends of the connecting rod 30. Each threaded section is movably threadedly connected to a threaded sleeve 31 with a corresponding internal thread.

[0023] The working principle of this device is as follows: During installation, first, tighten the two threaded sleeves 31 on the connecting rod 30 facing each other, so that the end of the connecting rod 30 passes through the threaded sleeves 31. Then, align the two ends of the connecting rod 30 and insert them into the two threaded blocks 24 on the screen assembly 20. Subsequently, rotate the two threaded sleeves 31 in the opposite direction, so that the threaded sleeves 31 move outward along the threads of the connecting rod 30 and are screwed into the internal threads of the threaded blocks 24 until the connecting rod 30 is firmly fixed to the screen frame 21. At this time, the connecting rod 30 can be used as an operating handle.

[0024] The operator holds the connecting rod 30 and places the screen assembly 20 into the frame 11 of the screen frame assembly 10, aligning it with the threaded groove 23 and threaded teeth 13, and rotates it clockwise. Under the action of the rotational torque, the screen assembly 20 will smoothly screw into the frame 11. When the edge of the flexible ring plate 22 contacts the inner wall of the frame 11 and undergoes elastic compression, it not only fills the gap between the two and achieves a seal, but its elastic restoring force also generates a radial component force, pressing the wire mesh frame 21 and the threaded surface of the frame 11 together, thus preventing loosening.

[0025] Once installed in place, loosen the threaded sleeve 31 in the reverse direction to easily remove the connecting rod 30, thus completing the entire installation process.

[0026] Disassembly is the reverse process: first install the connecting rod 30, then rotate it counterclockwise to quickly unscrew the screen assembly 20.

[0027] The electromechanical connections involved in this utility model are common practices used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments; they are common knowledge.

[0028] Components not described in detail in this article are existing technologies.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
