Description
Technical Field
[0001] This utility model relates to the field of chemical production technology, specifically to an acid pickling tank for chemical production. Background Technology
[0002] Pickling tanks are containers used for chemical treatment to remove rust, scale, and other impurities from the surfaces of various metal parts. They are alkali-resistant, acid-resistant, high-temperature resistant, and have good corrosion resistance, and can store various liquids. Different anti-corrosion resins (including ordinary ester resins, epoxy resins, and vinyl ester resins) are selected according to the concentration and temperature of the corrosive medium and are then combined with alkali-free glass mat or fiberglass cloth for production.
[0003] Currently, workers directly place the parts to be processed into the pickling tank containing the treatment solution.

[0023] like Figures 1-3As shown, this invention illustrates a pickling tank for chemical production in one embodiment, comprising: a pickling tank body 1, a limiting mark 2 fixedly installed at the upper end of the pickling tank body 1, an installation port 3 fixedly opened at the lower end of the pickling tank body 1, a heating coil 4 fixedly installed inside the installation port 3, installation grooves 5 fixedly opened on both sides of the pickling tank body 1, a filter plate 6 installed inside the pickling tank body 1, and a filter hole 7 fixedly opened at the upper end of the filter plate 6, and connecting rods 8 fixedly installed on both sides of the upper end of the filter plate 6, and connecting holes 9 fixedly opened at the upper end of the connecting rods 8.
[0024] For example, such as Figure 2 As shown, the restriction mark 2 is symmetrically installed on the front and back sides of the pickling tank body 1 with the pickling tank body 1 as the center reference. There are two installation slots on one side. The installation slots 5 are symmetrically installed on the left and right sides of the inner wall of the pickling tank body 1 with the pickling tank body 1 as the center reference.
[0025] For example, such as Figure 3 As shown, the size of the filter plate 6 fits the internal shape of the pickling tank body 1. There are two connecting rods on one side. The connecting rods 8 are symmetrically installed on the left and right sides of the filter plate 6 with the filter plate 6 as the center reference. The connecting rods 8 and the internal mounting groove 5 of the pickling tank body 1 form an interlocking connection. The connecting hole 9 is circular.
[0026] In some examples, limiting markers 2 are installed on the front and rear sides inside the pickling tank body 1 to control the solution level. Installation grooves 5 are opened on the left and right sides of the inner wall of the pickling tank body 1. A filter plate 6 with connecting rods 8 on both sides is placed into the pickling tank body 1, and the connecting rods 8 on both sides of the filter plate 6 are inserted into the corresponding installation grooves 5 on the inner wall of the pickling tank body 1, thus fixing the filter plate 6 in the tank. The treatment solution is poured into the pickling tank body 1, and the solution level is lower than the limiting markers 2 to prevent overflow. An auxiliary device is installed in the installation port 3 at the bottom of the pickling tank body 1. The heating coil 4 can heat the solution in the tank. The parts to be processed are placed into the pickling tank body 1 containing the solution using hoisting equipment or manually. When it is necessary to clean the impurities inside the pickling tank body 1, the upper end of the connecting rod 8 is fixedly provided with a connecting hole 9. The hoisting rope is connected to the connecting hole 9 at the upper end of the connecting rod 8, and the connecting rod 8 is hoisted, which drives the filter plate 6 to rise together. During the process of the filter plate 6 being hoisted, the solution inside the filter plate 6 flows back to the pickling tank body 1 through the filter hole 7 on the filter plate 6, while the impurities are intercepted by the filter plate 6 and left on top of it.
[0027] like Figures 4-7As shown, it illustrates a pickling tank for chemical production in another embodiment of the present invention, comprising: a suction fan 10 fixedly installed at the front of the top of the pickling tank body 1, an inlet 11 fixedly installed at the upper end of the suction fan 10, a conveying pipe 12 fixedly installed at the front end of the suction fan 10, and a central pipe 13 fixedly installed at the front end of the conveying pipe 12.
[0028] For example, such as Figure 6 As shown, a fixing plate 14 is fixedly installed at the rear of the top of the pickling tank body 1. A first sliding groove 15 is fixedly opened on the right side of the upper end of the fixing plate 14, and a first sliding rod 16 is fixedly connected inside the first sliding groove 15.
[0029] For example, such as Figure 7 As shown, a second sliding groove 17 is fixedly opened on the upper left side of the fixed plate 14. A second sliding rod 18 is fixedly connected inside the second sliding groove 17. An insertion groove 19 is fixedly opened above the second sliding groove 17, and an insertion plate 20 is fixedly connected inside the insertion groove 19. An installation plate 21 is fixedly installed at the front end of the second sliding rod 18, and a baffle plate 22 is fixedly installed at the upper end of the installation plate 21. A lower drain plate 23 is fixedly installed at the lower end of the installation plate 21.
[0030] For example, such as Figure 5 As shown, the suction fan 10 is connected to the pickling tank body 1 by a flange. There are three suction fans 10, and the number of conveying pipes 12 is the same as the number of suction fans 10.
[0031] For example, such as Figure 6 As shown, the first sliding groove 15 and the second sliding groove 17 have the same internal structure. The first sliding groove 15 is cross-shaped. The first sliding rod 16 and the second sliding rod 18 have the same structure. The first sliding rod 16 and the first sliding groove 15 form a sliding connection. The insertion groove 19 and the insertion plate 20 form an interlocking connection. The front end faces of the first sliding rod 16 and the second sliding rod 18 are in contact with the rear end face of the mounting plate 21.
[0032] In some examples, an suction fan 10 (usually arranged along the length) is installed on one side of the top of the pickling tank body 1. Multiple suction fans 10 are connected to a central pipe 13 through a conveying pipe 12. When the suction fan 10 is started, the acid mist generated in the tank is sucked in through its suction port 11. The acid mist is collected in the central pipe 13 through the conveying pipe 12 for centralized transportation and treatment. A fixing plate 14 is installed on the top of the opposite side of the pickling tank body 1 opposite to the fan. A first sliding groove 15 and a second sliding groove 17 (the internal cross section of the sliding groove is cross-shaped) are opened on the upper end of the fixing plate 14. A first sliding rod 16 is slidably connected to the first sliding groove 15, and a second sliding rod 18 is slidably connected to the second sliding groove 17. The front ends of the first sliding rod 16 and the second sliding rod 18 are connected to a mounting plate 21. An inclined baffle plate 22 is installed on the upper end of the mounting plate 21. An inclined lower drain plate 23 is installed at the lower end of the mounting plate 21. By sliding the first sliding rod 16 and the second sliding rod 18, the mounting plate 21 (and the baffle plate 22 and the lower drain plate 23 on it) is moved toward the opening of the pickling tank body 1. When the mounting plate 21 moves to the predetermined position (the opening of the pickling tank body 1), the upper end of the second sliding groove 17 is provided with an insertion groove 19. The insertion plate 20 is inserted into the insertion groove 19 to lock the position of the mounting plate 21. The inclined baffle plate 22 guides the rising acid mist in the tank to the side where the suction fan 10 is installed, so that the fan can effectively suck it up. The baffle plate 22 partially covers the upper opening of the pickling tank body 1 to reduce heat loss and play a role in heat preservation. The inclined lower drain plate 23 can guide the solution that condenses or drips along the inner wall of the baffle plate 22 to drip back into the pickling tank body 1, avoiding overflow or waste.
[0033] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
