Description

Technical Field

[0001] The utility model relates to the technical field of liquefied gas tank processing, in particular to a quenching device for liquefied gas tank processing. Background Technique

[0002] A liquefied gas tank is a reusable mobile seamless gas cylinder for containing high-pressure liquefied gases. Since a liquefied gas tank is a high-pressure container, strict material selection and heat treatment are required for it. Liquefied gas is gaseous at normal temperature and pressure and becomes liquid through compression and cooling. The liquefied gas tank provides a safe and stable storage space for liquefied gas, facilitating the large-scale storage of liquefied gas.

[0003] However, when traditional liquefied gas tanks are processed and quenched, it is necessary to remove dirt, dust, impurities, etc. on the outer wall surface of the liquefied gas tank before quenching. These pollutants may have an adverse impact during the heat treatment process, such as hindering heat transfer and causing uneven local temperature, thereby affecting the heat treatment effect and quality. Generally, cleaning and conveying are carried out separately. Workers first clean the outer wall of the liquefied gas tank, and then quench the liquefied gas tank through a conveying mechanism. This operation increases the labor intensity of the workers, increases the processing time for each liquefied gas tank, and reduces the processing efficiency of the liquefied gas tank. Therefore, it is urgent to solve such problems. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and to propose a quenching device for liquefied gas tank processing.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A quenching device for liquefied gas tank processing, including a quenching furnace body. Feeding and discharging mechanisms are arranged at both ends of the quenching furnace body. A liquefied gas tank body is arranged above the feeding and discharging mechanisms. A cleaning mechanism for cleaning the outer wall of the liquefied gas tank body is arranged on the outer wall of one end of the quenching furnace body;

[0007] The cleaning mechanism includes two symmetrical first L-shaped mounting plates fixed on the outer wall of one end of the quenching furnace body. The same second rotating rod is rotatably connected to the mutually approaching surfaces of the two first L-shaped mounting plates. Threaded rods are fixed on the outer walls of both ends of the second rotating rod, and the chute openings of the two threaded rods are opposite. Threaded nuts adapted to the threaded rods are arranged on the outer walls of the two threaded rods, and sliders are fixed on the outer walls of the threaded nuts. Second L-shaped connecting plates are fixed at the bottoms of the two sliders. Semi-circular scraping plates are fixed on the mutually approaching surfaces of the two second L-shaped connecting plates, and the semi-circular scraping plates are adapted to the outer wall of the liquefied gas tank body. When the sliders move, they will drive the semi-circular scraping plates to contact the outer wall of the liquefied gas tank body and scrape off the impurities on its outer wall.

[0008] As a further solution of the utility model, through holes communicating with each other are formed at both ends of the two sliders, and a same guide rod is slidably arranged in the through holes. Two ends of the guide rod are respectively fixed to one ends of the two first L-shaped mounting plates close to each other.

[0009] As a further solution of the utility model, springs are fixed to one surfaces of the two first L-shaped mounting plates close to each other. The other ends of the two springs are respectively fixed to bottoms of one ends of the two sliders. The springs are located on the outer wall of the guide rod. The springs can make the semi-circular scraping plate always contact with the outer wall of the liquefied gas tank body.

[0010] As a further solution of the utility model, one surfaces of the two lead screws close to each other are semi-circular surfaces. Feeding and discharging mechanisms are arranged at bottoms of two ends of the quenching furnace body.

[0011] As a further solution of the utility model, the feeding and discharging mechanism includes two U-shaped mounting frames. Two symmetric first rotating rods are rotatably connected to one surfaces of the two U-shaped mounting frames close to each other. Two first synchronous wheels are fixed to outer walls of the two first rotating rods. The four first synchronous wheels are in pairs correspondingly. First synchronous belts are arranged on outer walls of the two first synchronous wheels. A plurality of connecting rods are fixed to one surfaces of the two first synchronous belts close to each other. An arc-shaped placing block is fixed to the top of the connecting rod. The liquefied gas tank body is placed on the top of the arc-shaped placing block. The first synchronous belt can drive the arc-shaped placing block to move, so as to convey the liquefied gas tank body.

[0012] As a further solution of the utility model, motors are mounted on outer walls of one sides of the two U-shaped mounting frames. The two motors are respectively fixed to one ends of two of the first rotating rods.

[0013] As a further solution of the utility model, a second synchronous wheel is fixed to one end of one of the first rotating rods far from the motor, and another second synchronous wheel is fixed to one end of the second rotating rod far from the motor. A second synchronous belt is arranged on outer walls of the two second synchronous wheels. While conveying the liquefied gas tank body, the outer wall of the liquefied gas tank body can be cleaned through the second synchronous wheel, saving the processing time of each liquefied gas tank body.

[0014] The beneficial effects of the utility model are as follows:

[0015] For this utility model: due to the adoption of the second synchronous pulley, the second rotating rod, the lead screw, and the spring, when one of the first rotating rods drives the second synchronous pulley to rotate, the second synchronous pulley will drive another second synchronous pulley to rotate through the second synchronous belt, and the second rotating rod will drive the lead screw to rotate. At this time, the two sliders will approach each other. When the slider moves to the semi-circular surface, the spring will reset the slider, causing the semi-circular scraping plate to always contact the outer wall of the liquefied gas tank body and scrape off the impurities on its outer wall, effectively solving the problem mentioned in the background technology that general cleaning and transportation are carried out separately. First, the staff cleans the outer wall of the liquefied gas tank, and then quenches the liquefied gas tank through the transportation mechanism. This operation increases the labor intensity of the staff, and thus realizes the effect of cleaning the outer wall of the liquefied gas tank body while transporting it.

When the sliders 407 move, they will drive the semi-circular scraping plates 405 to contact the outer wall of the liquefied gas cylinder body 3 and scrape the impurities on its outer wall.

[0025] In this embodiment, through holes communicating with each other are opened at both ends of the two sliders 407, and a same guide rod 406 is slidably arranged in the holes. Both ends of the guide rod 406 are fixed to the ends of the two first L-shaped mounting plates 4 close to each other.

The other ends of the two springs 410 are respectively fixed to the bottoms of one ends of the two sliders 407, and the springs 410 are located on the outer wall of the guide rod 406. The springs 410 will keep the semi-circular scraping plates 405 in contact with the outer wall of the liquefied gas cylinder body 3 all the time.

[0027] In this embodiment, the surfaces of the two screw rods 408 close to each other are semi-circular surfaces 409, and feeding and discharging mechanisms are arranged at the bottoms of both ends of the quenching furnace body 1.

[0028] In this embodiment, the feeding and discharging mechanism includes two U-shaped mounting brackets 2 fixed thereto. On one side of the two U-shaped mounting brackets 2 that are close to each other, two symmetric first rotating rods 202 are rotatably connected. On the outer walls of the two first rotating rods 202, two first synchronous wheels 201 are fixed respectively. The four first synchronous wheels 201 are in pairs. On the outer walls of two first synchronous wheels 201, there are first synchronous belts 203 that are adapted to each other. On one side of the two first synchronous belts 203 that are close to each other, a number of connecting rods 204 are fixed.

While conveying the liquefied gas tank body 3, the outer wall of the liquefied gas tank body 3 can be cleaned by the second synchronous wheel 401, saving the processing time of each liquefied gas tank body 3.

[0031] Working principle: During use, with the feeding and discharging mechanism provided, first place the liquefied gas tank body 3 on the top of the arc-shaped placing block 205 at one end of the feeding port. Then start one of the motors 206. The motor 206 will drive the first rotating rod 202 to rotate. The first rotating rod 202 will drive the first synchronous pulley 201 to rotate. At this time, the first synchronous pulley 201 will drive another first synchronous pulley 201 to rotate through the first synchronous belt 203. When the first synchronous belt 203 moves, it will drive the connecting rod 204 to move. The connecting rod 204 will drive the arc-shaped placing block 205 to move. The arc-shaped placing block 205 will transport the liquefied gas tank body 3 into the quenching furnace body 1 for quenching treatment, thereby achieving the effect of quenching the liquefied gas tank body 3. With the cleaning mechanism provided, when one of the first rotating rods 202 rotates, it will drive the second synchronous pulley 401 to rotate.

At this time, the semi-circular scraper 405 will always contact the outer wall of the liquefied gas tank body 3. When the liquefied gas tank body 3 moves, the semi-circular scraper 405 will scrape off the impurities on the outer wall of the liquefied gas tank body 3, thereby achieving the effect of cleaning the outer wall of the liquefied gas tank body 3. After quenching is completed, open the motor 206 at the discharging port end to convey the liquefied gas tank body 3 out.
