Description

Technical Field

[0001] The utility model relates to the technical field of heat treatment devices, specifically referring to a heat treatment device for PC steel bars. Background Technique

[0002] The PC steel bar heat treatment device is a device used for heat-treating PC (prestressed concrete) steel bars. Prestressed concrete is a building material with high strength and good durability, and the PC steel bars in it play a role in enhancing the strength and stability of the concrete structure. PC steel bar heat treatment refers to heating the steel bars to a certain temperature and then changing the organizational structure of the steel by controlling the cooling rate to achieve the purpose of improving the strength and durability of the steel.

[0003] Common PC steel bar heat treatment devices are composed of a quenching furnace, a cooling device, and a conveying device. The following disadvantages are found during use:

[0004] 1. After using water to cool the PC steel bars in the cooling device, substances such as grease, metal particles, and oxides on the surface of the steel bars may remain in the water. These residues may pollute the water quality, affect the environment and health. If the water is not treated, it is easy to cause water pollution, and at the same time, the water cannot be recycled;

[0005] 2. The method of treating cooling water is usually to use chemical agents, such as degreasing agents, rust removers, etc., to treat the water to remove pollutants such as grease and metal oxides. However, before using chemical agents, the larger solid particles in the water are not filtered out in advance, which will increase the dosage of chemical agents. At the same time, the reaction between water and chemical agents usually uses a stirring device to react, and the existing stirring device cannot control its stirring rate, which will affect the reaction between water and chemical agents.

[0006] Therefore, in view of this, research and improvement are carried out on the existing structure, and a PC steel bar heat treatment device is proposed. Content of the Utility Model

A second water pump 402 is fixedly and penetratingly arranged at the top of the liquid purification tank 4, and the drain pipe 401 is fixedly and penetratingly connected to the second water pump 402. Through the cooperative arrangement of the first water pump 201 and the second water pump 402, the second water pump 402 can pump the water in the cooling device 2 into the liquid purification tank 4 for purification, and at the same time, the purified water can be pumped into the cooling device 2 by the first water pump 201, so as to cool the PC steel bar, enabling the water to be recycled and not affecting the cooling effect of the PC steel bar.

[0029] Please refer to Figure 1-3 , a collection and filtration assembly 5 is penetratingly arranged at the bottom of the drain pipe 401, and the collection and filtration assembly 5 filters and collects the solid particles in the liquid in the cooling device 2. The collection and filtration assembly 5 includes a shunt pipe 501 fixedly and penetratingly arranged at the bottom of the drain pipe 401 and a filter plate 502 fixedly arranged in the drain pipe 401, which can filter out some solid particles. The bottom end of the shunt pipe 501 is fixedly and penetratingly provided with an introduction box 503, and one end of the introduction box 503 extends into a collection box 504. A support plate 505 is hingedly arranged near the top in the introduction box 503, and a plurality of springs 506 are fixedly arranged between the bottom of the support plate 505 and one side in the introduction box 503. The arrangement of the shunt pipe 501 can introduce the filtered solid particles into the introduction box 503. When the solid particles have a certain weight, they will push the support plate 505 to rotate, thereby squeezing the springs 506, enabling the solid particles to enter the introduction box 503 and then into the collection box 504.

[0030] Please refer to Figure 1-2 , Figure 4, a liquid inlet is provided through the top of the liquid purification tank 4, and a cover body 403 is rotatably connected to the liquid inlet by threads. A stirring device (the stirring device is a prior art) is provided in the liquid purification tank 4. A control component 6 for driving the stirring device to rotate is provided on the top of the liquid purification tank 4, and the control component 6 controls the rotation speed of the stirring device. The control component 6 includes a rotating rod 601 rotatably provided on the top of the liquid purification tank 4. The rotating rod 601 is fixedly connected to the stirring device, and the rotation of the rotating rod 601 drives the stirring device to rotate. Three different-sized first gears 602 are fixedly sleeved on the rotating rod 601. Three Z-shaped plates 603 with different heights are slidably provided on the top of the liquid purification tank 4 around the rotating rod 601 in a uniformly distributed manner. A slider is fixedly provided at the bottom of the Z-shaped plate 603, and a sliding groove for cooperating with the slider to slide is provided on the top of the liquid purification tank 4.

The control component 6 can adjust and control the rotation speed of the stirring device. Since the three first gears 602 are of different sizes, the stirring device has three rotation speeds, so that water and chemical agents in different amounts can react fully during stirring.

[0031] The working principle of the present utility model:

[0032] When heat treatment of the PC steel bar is required, first place the PC steel bar on the conveying device 3, and then send the PC steel bar into the quenching furnace 1 through the conveying device 3, heat the PC steel bar to a certain temperature, and then send the PC steel bar into the cooling device 2 through the conveying device 3. The liquid purification tank 4 can store water. By starting the first water pump 201, the water in the liquid purification tank 4 can be pumped into the cooling device 2, so that the water can cool the PC steel bar. After most of the used water is stored in the cooling device 2, the second water pump 402 can be started to pump the water in the cooling device 2 into the liquid purification tank 4. When the water passes through the drain pipe 401, some solid particles will be filtered out by the filter plate 502, so that the solid particles enter the shunt pipe 501. After more solid particles are collected in the shunt pipe 501, the supporting plate 505 will be pressed downward due to the gravity of the solid particles, so that the spring 506 can be deformed, so that the solid particles enter the guiding box 503 and enter the collection box 504.

[0033] The water entering the liquid purification tank 4 from the cooling device 2 will rotate the cover body 403 to open the liquid inlet, and add chemical agents. Then, the stirring device can be controlled to rotate through the control component 6, so that the water and chemical agents can react fully. After the water is completely purified, the second water pump 402 can be started to pump the water in the liquid purification tank 4 into the cooling device 2 for use.

[0034] When it is necessary to adjust the rotation speed of the stirring device, first rotate the bolt 606 so that the bolt 606 moves away from the liquid purification tank 4. At this time, the Z-shaped plate 603 can be slid to adjust the position of the Z-shaped plate 603, so that one of the second gears 605 is meshed and connected with one of the first gears 602. Then, the motor 604 can be started to drive the rotation of one of the second gears 605. Since one of the second gears 605 is meshed and connected with one of the first gears 602, one of the first gears 602 rotates, causing the rotating rod 601 to rotate, thereby driving the stirring device to rotate. The larger the first gear 602 is, the slower the rotation speed is, and vice versa, the faster the rotation speed is.

[0035] The above describes the present invention and its implementation manners. Such a description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative efforts without departing from the spirit of the present invention, they shall fall within the protection scope of the present invention.
