Description

Technical Field

[0001] This utility model relates to the field of pickling tank technology, specifically to a pickling tank for an exhaust gas filtration device. Background Technology

[0002] The pickling line renovation project mainly involves adding a production line to the north side of the high-pressure water tank, adding steel columns, tracks, etc., and correspondingly adding tanks and loading / unloading devices to separate the pickling and phosphating processes. At the same time, some of the original tanks with insufficient functions need to be improved or replaced to ensure that the pickling and phosphating processes can be produced separately after the renovation, and that the production operation is smooth, thereby increasing output. In the process of producing bar and wire rods, pickling is required in the pickling tank to remove surface oxide scale, rust, and other impurities, making the surface clean. Currently, there are various types of pickling tanks on the market, but some shortcomings still exist.

[0003] Existing pickling tanks, by placing the materials to be cleaned inside for pickling, can lead to the accumulation and entanglement of materials during pickling, and the materials cannot be thoroughly pickled. These designs have shortcomings. For example, Chinese utility model patent CN217794876U discloses a corrosion-resistant pickling tank with a filtration device. The top of the support rod has two parallel support platforms, and the sides of the support platforms are evenly distributed with multiple limiting plates. The sides of the limiting plates have two limiting seats, and a transmission rod is rotatably connected to each limiting seat. The top of the transmission rod has a first transmission roller, and the bottom of the transmission rod has a clamp. This application includes an acid pickling tank, a lifting cylinder, a support rod, a support platform, a limiting plate, a limiting seat, a transmission rod, a first transmission roller, a support plate, a drive motor, a second transmission roller, transmission components, a drain port, a slot, a limiting frame, a limiting hole, a locking block, a filter bag, and a clamping structure. Compared with existing technologies, after the clamps fix the parts to be acid-picked, the drive motor drives the transmission components to move, which in turn drives all the transmission rods to rotate, thereby rotating the parts. This improves the acid pickling efficiency. However, this device generates waste gas during the acid pickling process, and direct discharge of this waste gas can cause environmental pollution. Therefore, we propose an acid pickling tank with a waste gas filtration device to solve the aforementioned problems. Utility Model Content

[0004] The purpose of this utility model is to provide an acid washing tank for an exhaust gas filtration device, so as to solve the problems of the current acid washing tanks mentioned in the background art. By directly placing the material inside the acid washing tank for acid washing, the material will become entangled and piled up during the acid washing process. At the same time, it is impossible to thoroughly acid wash the material. The acid washing design has shortcomings. In addition, the material will generate a certain amount of exhaust gas during the acid washing process. If the exhaust gas is directly discharged, it will cause environmental pollution and other problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an acid washing tank for a waste gas filtration device, comprising:

[0006] The pickling tank body is placed directly on the ground;

[0007] Also includes:

[0008] A filter screen box, wherein clamping mechanisms are arranged at equal intervals inside the filter screen box, wherein the clamping mechanisms include a support shaft, a support frame, a fixing plate, a connecting ring, a material body and a locking plate. A support shaft is installed above the middle part of the filter screen box, and a support frame is fixedly arranged at equal intervals below the support shaft. A fixing plate is installed on the front side below the support frame, and a connecting ring is arranged on the outer side of the fixing plate.

[0009] The filter box is provided with a full pickling mechanism on the outside. The full pickling mechanism includes a connecting rope, a rotating shaft, a connecting block and a motor. The connecting blocks are symmetrically installed on the upper left and right sides of the filter box, and the connecting rope is engaged with the upper part of the connecting block. The connecting rope is wrapped around the outside of the rotating shaft.

[0010] A filter screen box is slidably installed inside the pickling tank body, and a filter screen holder is fixedly installed below the filter screen box by bolts.

[0011] Preferably, a locking plate is slidably provided on the lower rear side of the support frame, and the locking plate is engaged with the fixing plate.

[0012] Preferably, the connecting ring has a material body inside.

[0013] Preferably, a rotating shaft is rotatably mounted on the upper middle part of the pickling tank body, and a motor is connected to the right end of the rotating shaft.

[0014] Preferably, an inlet is provided on the upper rear side of the pickling tank body, and an air suction pipe is fixedly connected to the upper middle part of the pickling tank body, and a purification box is provided in the middle of the air suction pipe.

[0015] Preferably, the purification chamber is internally fitted with an activated carbon bed plate, and an air pump is connected to the right side of the purification chamber.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: The pickling tank of this waste gas filtration device, by setting a clamping mechanism, can neatly clamp and fix the material, ensuring that the material will not accumulate or entangle during the pickling process. At the same time, a comprehensive pickling mechanism is set, which can drive the clamped and fixed material to move up and down, thereby enabling the material to be thoroughly pickled, which can improve the pickling accuracy. In addition, a waste gas filtration mechanism is set, which can purify the waste gas generated during the pickling process before discharge, effectively protecting the environment.

[0017] 1. The system is equipped with a filter screen box, a support shaft, a support frame, and a fixing plate. The filter screen box is installed inside the pickling tank body, and the support shaft is installed above the middle of the filter screen box. The support frame is installed at equal intervals below the support shaft. The fixing plate is fixedly installed on the lower front side of the support frame. In addition, a locking plate is slidably installed on the lower rear side of the support frame, which can fit the inner side of the connecting ring with the fixing plate. Then, the locking plate can be slid forward to lock into the fixing plate. That is, the locking plate and the fixing plate can limit the connecting ring between their locking connections. The material body is set below the connecting ring, so that the material body can be neatly arranged inside the filter screen box.

[0018] 2. Equipped with a filter screen box and a filter screen holder, the filter screen holder is fixed to the bottom of the filter screen box with bolts. When the material is pickled, the waste generated will flow down to the bottom of the filter screen box. The filter screen holder is located at the bottom of the filter screen box to intercept impurities in the pickling water inside the filter screen box. After the material is pickled, the pickling water can be discharged from the lower right side of the pickling tank, while the impurities will remain inside the filter screen box. Simply unscrew the bolts fixing the filter screen box and the filter screen holder to clean the impurities inside the filter screen box. The filtered water will not cause blockage of the drain pipe.

[0019] 3. Equipped with connecting ropes, a rotating shaft, connecting blocks, and a motor, the connecting blocks are symmetrically fixed on the upper left and right sides of the filter screen box. The connecting ropes are also connected to the top of the connecting blocks. The connecting ropes are wound around the rotating shaft located in the upper middle part of the pickling tank body. The motor is connected to the right end of the rotating shaft. When the motor is turned on, the rotating shaft can rotate. When the rotating shaft rotates, the connecting rope wound on the outside can be wound up and unwound. The connecting rope can cause the connecting blocks to move the filter screen box up and down inside the pickling tank body. The material body inside the filter screen box will also move along with it, which can create a slapping phenomenon with the pickling water, promote water flow, and help the material body be thoroughly cleaned.

[0020] 4. Equipped with an air suction pipe, a purification box, an activated carbon bed, and an air suction pump, the material body generates a certain amount of waste gas during the pickling process. The air suction pump connected to the right side of the purification box can be turned on. The air suction pump is located in the middle of the air suction pipe, and the left side of the air suction pipe is fixedly connected to the pickling tank body. When the air suction pump is turned on, the air suction pipe will have a certain suction force, which can draw the waste gas inside the pickling tank body into the purification box located in the middle of the air suction pipe. Since the purification box is equipped with an activated carbon bed, the activated carbon bed can effectively filter the waste gas. The filtered waste gas can be discharged from the right side of the air suction pipe.

[0021] 5. Equipped with a purification chamber and activated carbon bed plates, the exhaust gas can be filtered three times by setting three layers of activated carbon bed plates at equal intervals inside the purification chamber. At the same time, the activated carbon bed plates are interlocked with the purification chamber, which makes it easy to disassemble and replace. Attached Figure Description

[0030] 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.

[0031] Please see Figures 1-7 This utility model provides a technical solution:

[0032] Example 1: To address the problems existing in the prior art, this example provides the following technical solution: an acid pickling tank for a waste gas filtration device, comprising an acid pickling tank body 1; a clamping mechanism, located inside a filter screen box 2, which neatly arranges and fixes the material body 7 to be acid-washed, ensuring that no accumulation or entanglement occurs during the acid pickling process; a comprehensive acid pickling mechanism, located outside the filter screen box 2, which allows the filter screen box 2 to move up and down inside the acid pickling tank body 1, effectively promoting the flow of acid pickling water and facilitating comprehensive acid pickling of the material body 7; and a waste gas filtration mechanism, located above the acid pickling tank body 1, which purifies and then discharges the waste gas generated during the acid pickling process of the material body 7, effectively protecting the environment.First, open the front door of the pickling tank body 1 and place the material body 7 inside the filter box 2. Since a connecting ring 6 is located at the upper middle part of the material body 7, the inner side of the connecting ring 6 can contact the upper rear side of the fixing plate 5. Because the fixing plate 5 is fixedly located below the support frame 4, and a locking plate 8 is slidably located at the lower rear side of the support frame 4, when the inner side of the connecting ring 6 contacts the upper rear side of the fixing plate 5, the locking plate 8 can be slid forward and engaged with the fixing plate 5 due to the hollow middle part of the connecting ring 6. The connecting ring 6 can be positioned between the engaging plate 8 and the fixing plate 5, thus neatly and evenly placing the material body 7 in the filter box. Inside the pickling tank 1, the front door of the pickling tank body 1 is closed. Then, the mixed pickling water is poured into the pickling tank body 1 through the inlet 18 located at the rear of the upper middle part of the pickling tank body 1. The pickling water can soak the material body 7. Additionally, connecting blocks 12 are symmetrically installed on the left and right sides above the filter screen box 2. A connecting rope 10 is engaged with the top of the connecting block 12, and the top of the connecting rope 10 is wound around the rotating shaft 11. The rotating shaft 11 is located at the upper middle part of the pickling tank body 1. The motor 13 connected to the right end of the rotating shaft 11 can be turned on, allowing the rotating shaft 11 to rotate above the pickling tank body 1. When the rotating shaft 11 rotates, the connecting rope 10 rotates... The outer side of the rotating shaft 11 is wound or unwound, meaning the connecting rope 10 allows the connecting block 12 to move the filter screen box 2 up and down inside the pickling tank body 1. This up-and-down movement of the filter screen box 2 creates a pulsating effect with the water, promoting water flow and facilitating thorough pickling of the material body 7. Furthermore, the material body 7 generates some waste gas during the pickling process. At this point, the suction pump 17 can be turned on. The suction pump 17 is installed in the middle of the suction pipe 14, and the left side of the suction pipe 14 is fixedly connected to the top of the pickling tank body 1. A purification box 15 is installed in the middle of the suction pipe 14, allowing the suction pipe 14 to draw the waste gas from inside the pickling tank body 1 into the purification box 15. Activated carbon beds 16 are evenly spaced inside the purification chamber 15. These beds allow for three-stage purification and adsorption of the incoming waste gas. The purified gas is then discharged directly from the right side of the suction pipe 14. After the material body 7 has been pickled, the pickling water is discharged from the right side of the pickling tank body 1. The discharged water passes through a filter box 9, which is bolted to the bottom of the filter screen box 2. The filter box 9 intercepts impurities in the water, ensuring that the discharge pipe is not clogged by impurities even after long-term discharge. After the water is discharged, the front door of the pickling tank body 1 can be opened, and the bolts securing the filter box 2 and filter box 9 can be loosened to separate the filter box 9 from the filter screen box 2, allowing for cleaning of the inside of the filter box 9.

[0033] Existing pickling tanks, where materials are directly placed inside the tank body 1 for pickling, often result in material entanglement and accumulation during the pickling process. Therefore, this embodiment addresses this issue through the following technical solution: Figure 2 , Figure 6 and Figure 7 As shown, the clamping mechanism includes a support shaft 3 located above the middle of the filter box 2. Support frames 4 are installed at equal intervals below the support shaft 3. A fixing plate 5 is fixedly installed on the lower front side of the support frame 4. In addition, a locking plate 8 is slidably arranged on the lower rear side of the support frame 4, which can fit the inner side of the connecting ring 6 with the fixing plate 5. Then, the locking plate 8 can be slid forward to lock into the fixing plate 5. That is, the locking plate 8 and the fixing plate 5 can limit the connecting ring 6 between their locking connections. Furthermore, a material body 7 is arranged below the connecting ring 6, which can neatly arrange the material body 7 inside the filter box 2, effectively avoiding the phenomenon of accumulation and entanglement during subsequent pickling.

[0034] Example 2: Existing pickling tanks have shortcomings in their design because they cannot perform comprehensive pickling of materials. Therefore, this example addresses these shortcomings by implementing the following technical solution: Figure 2 , Figure 5 and Figure 6 As shown, the comprehensive pickling mechanism includes connecting blocks 12 located on the left and right sides above the filter box 2. Connecting ropes 10 are engaged and connected to the top of the connecting blocks 12. The connecting ropes 10 are wound around the rotating shaft 11 located above the middle of the pickling tank body 1. In addition, a motor 13 is connected to the right end of the rotating shaft 11. When the motor 13 is turned on, the rotating shaft 11 can rotate. When the rotating shaft 11 rotates, the connecting ropes 10 wound on the outside can be wound up and unwound. That is, the connecting ropes 10 can cause the connecting blocks 12 to move the filter box 2 up and down inside the pickling tank body 1. That is, the material body 7 inside the filter box 2 will also move along with it, which can create a slapping phenomenon with the pickling water, which can promote the flow of water and help the material body 7 to be thoroughly cleaned.

[0035] Example 3: Existing pickling tanks generate waste gas during the pickling process. Directly discharging this waste gas would cause environmental pollution. Therefore, this example uses the following technical solution: Figure 2 , Figure 3 and Figure 4As shown, the exhaust gas filtration mechanism includes an air suction pump 17 installed above the pickling tank body 1. Since the air suction pump 17 is located on the right side of the purification box 15, and the purification box 15 is installed in the middle of the suction pipe 14, the left side of the suction pipe 14 is fixedly connected to the pickling tank body 1. When the air suction pump 17 is started, the suction pipe 14 will have a certain suction force, which can draw the exhaust gas inside the pickling tank body 1 into the purification box 15 located in the middle of the suction pipe 14. Since the purification box 15 is equipped with an activated carbon bed plate 16, the activated carbon bed plate 16 can effectively filter the exhaust gas. The filtered exhaust gas can be discharged from the right side of the suction pipe 14, which can effectively protect the environment.
