Description

Technical Field

[0001] The utility model relates to the field of pickling tanks, in particular to a pickling tank with a cooling mechanism. Background Art

[0002] During metal pipe processing, to remove impurities such as grease and dirt from the surface and to passivate the pipe surface, the pipes, after welding and other processes, are placed in a pickling tank for pickling. However, during the pickling process, the chemical reaction between the acid and the pipe surface and the operation of the liquid vibration mechanism generate a large amount of heat. If the temperature is not promptly reduced, the excessively high temperature will accelerate the volatilization of the acid, resulting in a decrease in the acid concentration in the pickling tank, which may affect the pickling effect. Utility Model Content

[0003] The purpose of the utility model is to solve the above problems and provide a pickling tank with a cooling mechanism, which can reduce the temperature of the pickling tank during operation and improve the pickling effect.

[0004] To achieve the above objectives, the present invention employs a technical solution comprising a pickling tank with a cooling mechanism, comprising a tank body and a support. The tank body has an open upper end and a drain outlet at its lower portion. A cooling pipe is disposed within the tank body. The support comprises a crossbeam with vertical columns spaced along its length, extending toward the bottom of the tank body. Lateral support beams are disposed on the sidewalls of the columns. The cooling pipe removes heat from the tank body, thereby lowering the temperature of the liquid within the pickling tank and improving the pickling effect. Pipes to be cleaned are placed on the support, facilitating easy access and improved work efficiency.

[0005] Furthermore, the cooling pipe is spirally arranged along the inner wall of the tank body to expand the contact area between the cooling pipe and the liquid in the tank body, thereby avoiding uneven temperature in the tank body.

[0006] Furthermore, the cooling method is water cooling, and for this purpose, both ends of the cooling pipe extend out of the trough body and are connected to the water tank, and a water pump is provided in the water tank.

[0007] Furthermore, in order to facilitate the removal and placement of the bracket, support part groups are arranged at intervals along the length direction of the beam, and the support part groups include support beams arranged on both sides of the beam, and the support beams are arranged horizontally; a holder that cooperates with the support beam is provided at the upper end of the side wall of the trough body, and a slot is provided on the holder to prevent the bracket from moving during the pickling process.

[0008] Furthermore, an upwardly extending baffle is provided at the outer end of the placement beam, and the upper end surface of the baffle is higher than the upper end surface of the placement beam, thereby preventing the pipe from falling from the placement beam as much as possible.

[0009] Furthermore, a placement portion is provided at the lower end of the column, so that when the bracket is placed on the ground outside the trough body, etc., it can effectively prevent the bracket from tipping over.

[0010] Furthermore, an ultrasonic generator is installed on the tank body, and the ultrasonic generator vibrates the liquid in the tank body to improve the cleaning efficiency and quality.

[0011] Furthermore, the side wall of the tank body is a double-layer structure, thereby achieving protection and a certain shielding effect.

[0012] The beneficial effects of the utility model are as follows: the utility model has a simple structure, and when pickling is in progress, the cooling pipe cools down the liquid in the pickling tank to avoid the acid liquid in the pickling tank being too high in temperature, thereby improving the pickling effect.

[0018] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention.

[0019] Example 1, as Figure 1-4As shown, the structure of this embodiment is a pickling tank with a cooling mechanism, which includes a tank body 1 and a bracket. The side wall of the tank body 1 is a double-layer structure, which is hollow inside, and the upper end of the tank body 1 is open. In this embodiment, the tank body 1 is a rectangular structure, and a drain outlet 2 is provided at the lower part of the tank body 1. The drain outlet 2 is connected to the drain pipe, and a valve is provided at the drain outlet 2. A cooling pipe 3 is provided in the tank body 1, and the cooling pipe 3 can be electrically cooled. In this embodiment, the cooling pipe 3 adopts a conveying pipe made of acid-resistant and corrosion-resistant materials such as polytetrafluoroethylene. The cooling pipe 3 is spirally arranged along the inner wall of the tank body 1, and the liquid inlet and liquid outlet ends of the cooling pipe 3 both extend out of the tank body 1 and are respectively connected to the water outlet pipe and the water inlet pipe of the water tank. A water pump is provided in the water tank to inject coolant into the cooling pipe 3, and the coolant in the cooling pipe 3 returns to the water tank from the liquid outlet end. An ultrasonic generator 11 is installed on the tank body 1.

[0020] The bracket includes a crossbeam 4. In this embodiment, the crossbeam 4 is in the same direction as the tank body 1. The lower end of the crossbeam 4 is provided with columns 5 at intervals along its length direction. The columns 5 are arranged vertically. The side walls of the columns 5 are provided with placement beams 6. Multiple placement beams 6 can be arranged vertically. The placement beams 6 are arranged along the width direction of the crossbeam 4. The outer end of the placement beam 6 is provided with an upward extending baffle 9. The lower end of the column 5 is provided with a placement portion 10. The outer diameter of the placement portion 10 is smaller than the internal size of the tank body 1. The placement portion 10 can be a planar frame structure formed by welding multiple pipes to reduce the weight of the bracket and facilitate sinking below the liquid level of the tank body 1.

[0021] The upper end of the beam 4 is provided with support part groups at intervals along its length direction, and the support part groups include support beams 7 arranged on both sides of the beam 4. The support beams 7 are arranged along the width direction of the beam 4. The length of the support part group is greater than the inner width of the trough body 1. The upper end of the side wall of the trough body 1 is provided with a socket 8 that cooperates with the support beam 7, and the socket 8 is provided with a downwardly concave slot.

[0022] The specific working process is as follows: the pickling liquid is injected into the tank body 1, and at the same time, the staff places multiple pipes to be cleaned on different placement beams 6 respectively, and then places the bracket into the tank body 1 by driving, manual labor, etc. until the support beam 7 is located in the slot. At this time, the pipes to be cleaned are sunk in the pickling liquid, and the staff turns on the ultrasonic generator 11 to pickle the pipes.

[0023] After the pickling is completed, the bracket is removed from the tank body 1, thereby achieving the purpose of taking out multiple pipes at a time and improving the pickling efficiency.
