[0001] This utility model relates to the field of filtration device technology, specifically a fume filtration device for computer chip welding. Background Technology

[0002] Computer chip soldering is a step in electronics manufacturing, which generates fumes. If these fumes are emitted directly, they will harm the respiratory health of operators, pollute the workshop environment, and affect the operation of precision equipment. Therefore, fume filtration devices are needed to filter the fumes. For example, the authorized patent with announcement number CN211837011U (a fume purification device for electronic circuit welding) includes an upper shell, the interior of which is a hollow structure, a base fixedly connected to the bottom of the upper shell, an air inlet pipe provided on one side of the upper shell, one side of which penetrates the upper shell and contacts its inner wall, and a fixed box fixedly connected to the middle position of the top of the upper shell, the interior of which is a hollow structure. While the existing technologies mentioned above facilitate the replacement of activated carbon, they lack an online replacement structure. Consequently, the device needs to be shut down when the activated carbon is replaced, resulting in an interruption of the flue gas treatment process and hindering stable and continuous flue gas filtration. Therefore, there is an urgent market need to develop a flue gas filtration device for computer chip welding to help solve the existing problems. Utility Model Content

[0003] The purpose of this invention is to provide a fume filtration device for computer chip welding, in order to solve the problem mentioned in the background art that the device needs to be stopped when the activated carbon is replaced, which leads to the interruption of the fume treatment process and makes it inconvenient for the stable and continuous filtration of the fume.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a fume filtration device for computer chip welding, comprising a filter housing, a filter column rotatably mounted inside the filter housing, the lower end of the filter column extending movably to the bottom of the filter housing, slots symmetrically arranged at the top and bottom of the filter column, a second side groove arranged along one side of the slots inside the filter column, an activated carbon box arranged at one end of the slots near the second side groove, the activated carbon box being fixedly connected to the filter column by screws, and activated carbon granules arranged inside the activated carbon box.

The push rod end of the electric cylinder slides into the interior of the filter box and is fixedly connected to the push plate.

[0010] Preferably, straight rods are fixedly installed at the four corners below the filter box, and mounting plates are fixedly installed below the straight rods.

[0011] Compared with the prior art, the beneficial effects of this utility model are: (1) This utility model realizes the online switching function of activated carbon filter unit through the rotating structure of filter column and the symmetrically arranged slot design. The activated carbon can be replaced without stopping the machine, which effectively ensures the continuity and stability of flue gas filtration and avoids the production line interruption problem caused by maintenance of traditional filter devices. In addition, the activated carbon box is fixed by screws and has a vent hole, which ensures both sealing and easy disassembly and assembly, increasing its practicality.

[0012] (2) The utility model sets a side groove on the other side of the slot and installs the filter cloth together.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Please see Figure 1-5 This utility model provides an embodiment of a computer chip welding fume filtration device, comprising a filter box 1, a filter column 7 rotatably mounted inside the filter box 1, the lower end of the filter column 7 extending movably to the bottom of the filter box 1, a sealing ring provided at the contact point between the filter column 7 and the lower end surface of the filter box 1 to prevent the fume inside the filter box 1 from flowing downwards, slots 701 symmetrically arranged at the top and bottom of the filter column 7, a side groove 703 provided along one side of the slot 701 inside the filter column 7, an activated carbon box 15 provided at one end of the slot 701 near the side groove 703, the activated carbon box 15 being fixedly connected to the filter column 7 by screws, activated carbon granules being provided inside the activated carbon box 15, and several through holes provided on both end faces of the activated carbon box 15 for airflow.

[0018] During operation, the activated carbon box 15 located in the upper slot 701 is in the state of adsorbing and filtering flue gas. When the activated carbon needs to be replaced, there is no need to stop the machine. By driving the filter column 7 to rotate, the lower slot 701, which was originally in the standby state, rotates to the upper working position and takes over the upper slot 701 to continue filtering flue gas, ensuring that the flue gas treatment process is uninterrupted. At the same time, the activated carbon box that was originally in the upper position rotates with the filter column 7 to the lower part of the filter box 1, which can be easily disassembled and replaced. This realizes the online switching function of the activated carbon filter unit, and the activated carbon replacement can be completed without stopping the machine, effectively ensuring the continuity and stability of flue gas filtration.

[0019] Please see Figure 4 The filter column 7 has a side groove 702 on the other side of the slot 701 inside. The side groove 702 has a filter cloth 13 inside. The filter cloth 13 has a frame 14 fixedly installed on the outside of the frame 14 and is fixedly connected to the filter column 7 by screws.

[0020] The filter cloth 13 enables preliminary filtration of flue gas, reduces dust pollution and damage to activated carbon, thereby extending the service life of activated carbon, reducing the frequency and cost of activated carbon replacement, and improving the economy and practicality of the entire flue gas filtration device.

[0021] Please see Figure 3 A sealing top block 16 is fixedly installed inside the filter box 1 along the outer side of the filter column 7. The sealing top block 16 is in close contact with the filter column 7. A motor 6 is fixedly installed on one side of the filter box 1. The motor 6 is a servo motor with self-locking and angle detection capabilities. The output end of the motor 6 is fixedly connected to the filter column 7.

[0022] The sealing top block 16 is in close contact with the filter column 7, forming a relatively sealed space. This ensures that the flue gas can only be filtered through the filter cloth 13 and activated carbon box 15 inside the filter column 7, improving the reliability and effectiveness of filtration. At the same time, the motor 6 provides power for the rotation of the filter column 7, enabling online switching of the activated carbon box 15, ensuring the continuity and stability of flue gas filtration, and improving the automation level and ease of operation of the device.

[0023] Please see Figure 1 A smoke inlet pipe 2 is fixedly installed on one side of the filter box 1. The smoke inlet pipe 2 extends to the computer chip welding fixture through an external pipe and can stably absorb the smoke generated by the computer chip welding. A fan box 3 is fixedly installed on the other side of the filter box 1. A fan is fixedly installed inside the fan box 3. An exhaust pipe 4 is fixedly installed on one side of the fan box 3.

[0024] The arrangement of the inlet pipe 2, the fan, and the exhaust pipe 4 forms a complete flue gas flow channel. The inlet pipe 2 can introduce the flue gas generated during the computer chip welding process into the filter box 1 for filtration. The fan provides strong suction, ensuring that the flue gas can pass through the filter device quickly and smoothly, thus improving the filtration efficiency.

[0025] Please see Figure 2 and Figure 3Inside the filter housing 1, a push plate 11 is provided along one side of the filter column 7. A scraper 12 is fixedly installed below the push plate 11. A cover 5 is fixedly installed on one side of the front end of the filter housing 1 by screws. An electric cylinder 10 is fixedly installed on one side of the rear end of the filter housing 1. The push rod end of the electric cylinder 10 slides into the interior of the filter housing 1 and is fixedly connected to the push plate 11.

[0026] During the flue gas filtration process, some dust will be deposited at the bottom of the filter box 1 on one side of the filter cloth 13. The electric cylinder 10 can drive the push plate 11 and scraper 12 to move inside the filter box 1. The scraper 12 can scrape away the deposited dust, and the dust can be easily removed by opening the box cover 5, which increases the practicality.

[0027] Please see Figure 1 Straight rods 8 are fixedly installed at the four corners below the filter box 1, and mounting plates 9 are fixedly installed below the straight rods 8.

[0028] The straight rod 8 and mounting plate 9 facilitate the support and installation of the device, increasing its practicality.

[0029] Working principle: During use, the welding fumes are first drawn into the filter box 1 by the negative pressure of the fan box 3 through the smoke inlet pipe 2. The fumes are forced through the filter column 7 in the sealed space formed by the sealing top block 16: first, they pass through the filter cloth 13 in the side groove 702 for primary dust removal, intercepting large dust particles, and then enter the activated carbon box 15 in the upper slot 701. The activated carbon particles inside adsorb harmful gases and dust. When the activated carbon needs to be replaced, the motor 6 drives the filter column 7 to rotate 180°, so that the pre-installed spare activated carbon box 15 below automatically switches to the working position to continue filtering. At the same time, the original activated carbon box 15 rotates to the bottom, and the operator can open the box cover 5 to disassemble and replace it, realizing maintenance without stopping the machine. This achieves efficient and continuous treatment of welding fumes and increases practicality.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
