Description

Technical Field

[0001] This utility model relates to the field of combined screen technology, specifically a multifunctional combined screen. Background Technology

[0002] Material screening is a crucial process in various fields such as production, agricultural processing, food manufacturing, and mineral screening. Its purpose is to separate materials of different particle sizes, shapes, or properties to meet the needs of subsequent processing, grading, and purification. Traditional screening equipment often suffers from problems such as single function, poor adaptability, and low efficiency, making it difficult to meet the screening needs of modern production for multiple varieties and specifications of materials. Therefore, multi-functional combined screens have emerged.

[0003] Chinese Utility Model Patent Publication No. CN205518575U discloses a multi-functional combined vibrating screen. The specification of this multi-functional combined vibrating screen states that it can input different materials to be screened into screens of corresponding mesh sizes according to the particle size requirements of the material sample. Simultaneously, the materials screened by each screen fall into a lower material receiving and mixing container, achieving repeated and uniform mixing. However, this multi-functional combined vibrating screen lacks a buffer structure, making it difficult to reduce the impact force on the screen plates during vibration screening. This can easily lead to scratches on the screen plates due to their rigid connection, affecting their subsequent normal use. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a multifunctional combined screen, which can effectively solve the problem in the prior art that the lack of a buffer structure makes it difficult to reduce the impact force on the screen plate during vibrating screening, which easily leads to scratches on the screen plate due to rigid connection, thus affecting its subsequent normal use.

[0005] The technical solution adopted by this utility model is: a multi-functional combined sieve, including a support frame and a sieve frame, a vibrator is fixedly installed at the connection end of the support frame and the sieve frame, a support column is fixedly installed on the inner wall of the sieve frame, a sieve plate mounting assembly is provided at the inner edge of the sieve frame, and a vibration adjustment assembly is fixedly installed on the sieve frame through the sieve plate mounting assembly.

[0006] The sieve plate mounting assembly includes a mounting frame and a limiting frame. A mounting base is fixedly installed at the end of the mounting frame away from the limiting frame, and a limiting groove is opened at the end of the limiting frame away from the mounting frame. The sieve plate body is snapped into the limiting frame through the limiting groove.

[0007] The vibration adjustment assembly includes a limiting post fixedly installed with the mounting base. A connecting post is fixedly installed at the end of the limiting post away from the mounting frame. A movable plate is slidably connected to the outer edge of the connecting post. A spring is fixedly installed at the end of the movable plate away from the limiting frame.

[0008] Preferably, the movable plate is adapted to the connecting column, and the movable plate abuts against the limiting frame.

[0009] Through the above technical solution, by adapting the movable plate to the connecting column and abutting against the limiting frame, the elastic force of the spring can be transmitted to the limiting frame through the movable plate. When the vibration motor is working, the extension and contraction of the spring can buffer the vibration impact, making the screen plate body vibrate more smoothly and avoiding damage to the screen plate body caused by rigid connection.

[0010] Preferably, the limiting frame has a through-hole extending away from the mounting frame, and there are multiple identical positioning holes, which are distributed at equal intervals.

[0011] The above technical solution allows the screen plate body to be fixed by fasteners through multiple equally spaced positioning holes, preventing the screen plate body from shifting during screening. In addition, the equally spaced design ensures that the screen plate body is subjected to uniform force, avoiding local loosening that could affect its normal use.

[0012] Preferably, there are three sieve plate bodies, which are located on the same vertical horizontal line, and the sieve plate body of the uppermost layer has a sieve mesh of 200-300 mesh.

[0013] The above technical solution allows for fine initial screening of materials through the top 200-300 mesh sieve plate, intercepting large particles or agglomerated materials and preventing them from clogging the sieve plate body. It can be used as the first step in screening, reducing the burden on the lower sieve plates and improving the overall screening efficiency. It is suitable for materials containing a large amount of fine particles.

[0014] Preferably, the middle layer of the sieve plate has a screen mesh of 30-80 mesh, and the bottom layer of the sieve plate has a screen mesh of 20-30 mesh.

[0015] Through the above technical solution, the middle layer of 30-80 mesh screen plate can separate medium-sized particles from the primary screened material, while the bottom layer of 20-30 mesh screen plate screens out coarser particles, forming a three-level stratified screening. The combination of different mesh sizes can complete the classification of multiple particle sizes of materials at one time, without the need for multiple screenings, thus improving work efficiency and meeting diverse material grading needs.

[0016] Preferably, a feed frame is fixedly installed at the end of the screen frame away from the support frame, and an inspection door is provided at the end of the screen frame away from the support frame.

[0017] The above technical solution guides the material into the screen frame through the feed frame, preventing material from accumulating in certain areas and affecting the screening effect. In addition, the inspection door makes it easy to open the screen frame and repair the internal screen plate, reducing equipment downtime and improving maintenance convenience.

[0018] Preferably, a multi-stage discharge hopper is fixedly installed at the end of the screen frame away from the feed frame, and a waste discharge frame and a vibration motor are fixedly installed at the end of the screen frame away from the feed frame.

[0019] Through the above technical solution, the multi-stage discharge hopper corresponds one-to-one with the three-layer screen plate body, which can collect screening products of different particle sizes respectively, realize the graded output of materials, and the waste discharge frame is used to discharge impurities or coarse materials that cannot pass through the bottom screen plate, avoiding accumulation and blockage.

[0020] Compared with the prior art, this utility model provides a multifunctional combined sieve with the following advantages:

[0021] 1. This multi-functional combined screen, through the design of three screen plates with different mesh sizes, can form a three-level layered screening. The combination of different mesh sizes can complete the classification of multiple particle sizes of materials in one go, eliminating the need for multiple screenings, improving work efficiency, meeting diverse material grading needs, and thus facilitating the improvement of the overall combination screen's versatility and practicality, making it easy to promote its use.

[0022] 2. This multi-functional combined screen uses a movable plate that is adapted to the connecting column and abuts against the limiting frame. The elastic force of the spring can be transmitted to the limiting frame through the movable plate. When the vibrating motor is working, the extension and contraction of the spring can buffer the vibration impact, making the screen plate body vibrate more smoothly and avoiding damage to the screen plate body caused by rigid connection.

A mounting base 902 is fixedly mounted on the end of the mounting frame 901 away from the limiting frame 903. A limiting groove 904 is opened on the end of the limiting frame 903 away from the mounting frame 901. The sieve plate body 906 is snapped into the limiting frame 903 through the limiting groove 904.

[0033] The vibration adjustment assembly 11 includes a limiting post 1101 fixedly installed with the mounting base 902. A connecting post 1102 is fixedly installed at the end of the limiting post 1101 away from the mounting frame 901. A movable plate 1103 is slidably connected to the outer edge of the connecting post 1102. A spring member 1104 is fixedly installed at the end of the movable plate 1103 away from the limiting frame 903.

[0034] Specifically, the movable plate 1103 is adapted to the connecting column 1102, and the movable plate 1103 abuts against the limiting frame 903. The advantage is that, through the adaptation of the movable plate 1103 to the connecting column 1102 and the abutment against the limiting frame 903, the elastic force of the spring 1104 can be transmitted to the limiting frame 903 through the movable plate 1103. When the vibration motor 7 is working, the extension and contraction of the spring 1104 can buffer the vibration impact, making the screen plate body 906 vibrate more smoothly and avoiding damage to the screen plate body 906 caused by rigid connection.

[0035] Specifically, the limiting frame 903 has a through-hole 905 located away from the mounting frame 901. Multiple positioning holes 905 are provided, and the multiple positioning holes 905 are distributed at equal intervals. The advantage is that the screen plate body 906 can be fixed by fasteners through the multiple equally distributed positioning holes 905, preventing the screen plate body 906 from shifting during the screening process. In addition, the design of equal intervals can ensure that the screen plate body 906 is subjected to uniform force, avoiding local loosening that would affect its normal use.

[0036] Specifically, there are three screen plate bodies 906, which are located on the same vertical horizontal line. The uppermost screen plate body 906 has a screen mesh of 200-300 mesh. The advantage is that the material can be finely screened through the uppermost 200-300 mesh screen plate body 906, intercepting large particles or agglomerated materials and preventing them from clogging the screen plate body 906. It can be used as the first step in screening, which can reduce the burden on the lower screen plate bodies 906 and improve the overall screening efficiency. It is suitable for materials containing a lot of fine particles.

[0037] Example 2: Figure 2 As shown in Figure 6, this is an improvement on the previous embodiment.

[0038] Specifically, the middle layer screen plate body 906 has a screen mesh of 30-80 mesh, and the bottom layer screen plate body 906 has a screen mesh of 20-30 mesh. The advantage is that the middle layer 30-80 mesh screen plate body 906 can separate medium-sized particles from the initial screened material, while the bottom layer 20-30 mesh screen plate screens out coarser particles, forming a three-stage stratified screening. The combination of different mesh sizes can complete the classification of multiple particle sizes of materials at one time, without the need for multiple screenings, thus improving work efficiency and meeting diverse material grading needs.

[0039] Specifically, a feed frame 4 is fixedly installed at the end of the screen frame 3 away from the support frame 1, and a maintenance door 5 is set at the end of the screen frame 3 away from the support frame 1. The advantage is that the feed frame 4 can guide the material into the screen frame 3, avoiding the accumulation of material in a local area and affecting the screening effect. In addition, the maintenance door 5 makes it easy to open the screen frame 3 and repair the internal screen plate body 906, reducing equipment downtime and improving maintenance convenience.

[0041] Working Principle: During use, the movable plate 1103 is adapted to the connecting column 1102 and abuts against the limiting frame 903. The elastic force of the spring 1104 can be transmitted to the limiting frame 903 through the movable plate 1103. When the vibrating motor 7 is working, the extension and contraction of the spring 1104 can buffer the vibration impact, making the screen plate body 906 vibrate more smoothly and avoiding damage to the screen plate body 906 caused by rigid connection. The screen plate body 906 can be fixed by fasteners through multiple equally spaced positioning holes 905 to prevent the screen plate body 906 from shifting during screening. In addition, the equally spaced design can ensure that the screen plate body 906 is evenly stressed, avoiding local loosening that would affect its normal use. The uppermost 200-300 mesh screen plate body 906 can perform fine initial screening of materials, intercepting large particles or agglomerated materials and preventing them from clogging the screen plate body 906. It can be used as the first step in screening, which can reduce the burden on the lower screen plates. The 906 screen plate improves overall screening efficiency and is suitable for materials containing a large amount of fine particles. The middle layer 30-80 mesh screen plate body 906 can separate medium-sized particles from the initial screening material, while the bottom 20-30 mesh screen plate screens out coarser particles, forming a three-stage stratified screening. Different combinations of mesh sizes can classify multiple particle sizes of materials at once, eliminating the need for multiple screenings, improving work efficiency, and meeting diverse material grading needs. The feed frame 4 guides the material into the screen frame 3, preventing material accumulation in certain areas from affecting the screening effect. The inspection door 5 facilitates opening the screen frame 3 for maintenance of the internal screen plate body 906, reducing equipment downtime and improving maintenance convenience. The multi-stage discharge hopper 6 corresponds one-to-one with the three-layer screen plate body 906, which can collect screening products of different particle sizes to achieve graded output of materials. The waste discharge frame 10 is used to discharge impurities or coarse materials that cannot pass through the bottom screen plate, preventing accumulation and blockage.
