Technical Field

[0001] The present application relates to the technical field of chlorine liquefaction equipment, and in particular to a chlorine liquefaction device. Background Art

[0002] Chlorine is one of the main products of the chlor-alkali industry. It can react with organic and inorganic substances to form a variety of chlorides through substitution and addition reactions. It is a key raw material in many chemical production processes. In order to facilitate transportation and storage, chlorine usually needs to be liquefied.

[0003] The existing Chinese utility model patent document with authorization announcement number CN218034520U discloses a low-pressure chlorine liquefaction equipment, including a processing box, in which a liquefaction spiral tube is installed. The temperature in the processing box is reduced by a refrigeration unit, and the pressure is reduced by a vacuum pump, so that the chlorine is liquefied in a re-liquefaction recovery pipe and collected.

[0004] In this technical solution, an observation window is installed on the side wall of the processing box to facilitate observation of the internal situation of the processing box. However, due to the internal cooling and vacuuming methods, the inner wall of the observation window is prone to fogging, affecting the observation of the staff. Summary of the invention

[0005] In order to facilitate cleaning of the observation window, the present application provides a chlorine liquefaction device.

[0006] This application adopts the following technical solutions: A chlorine liquefaction device comprises a treatment box, an observation window arranged on the treatment box, and a wiping structure arranged inside the treatment box and used to clean the observation window, wherein the wiping structure comprises a frame arranged in the treatment box, a scraper connected to the frame for sliding up and down, and a driving source installed on the frame; the scraper comprises a connecting seat and a scraper bar installed on the connecting seat, the scraper bar is slidably connected to the connecting seat, the connecting seat is slidably connected to the frame up and down, and the driving source is used to drive the connecting seat to slide up and down on the frame, the scraper bar is slidably connected to a side of the connecting seat close to the observation window, when the connecting seat slides downward, the scraper bar abuts against the surface of the observation window, when the connecting seat moves upward, the scraper bar slides in a direction close to the connecting seat so that the scraper bar and the observation window are separated.

[0007] By adopting the above technical solution, when the connecting seat slides downward, it comes into contact with the observation window, thereby scraping off the oil droplets on the observation window. When the connecting seat moves upward, the scraper strip and the observation window are separated, so that the scraper strip will no longer scrape the oil droplets upward. This reciprocating process achieves a good cleaning effect on the observation window.

[0008] Optionally, the connecting seat has an internal hollow structure, and the scraper strip is provided with a sliding rod which slides through the side wall of the connecting seat and extends into the inner cavity of the connecting seat, and a linkage rod is provided at one end of the sliding rod inside the connecting seat, and a first elastic member is provided on the outer wall of the sliding rod, and the first elastic member is connected between the linkage rod and the inner wall of the connecting seat, and the linkage rod cooperates with the inner wall of the frame, and when the connecting seat moves downward, the linkage rod moves in a direction close to the observation window so that the scraper strip abuts against the observation window, and the first elastic member is compressed; when the connecting seat moves upward, the linkage rod moves in a direction away from the observation window.

[0009] By adopting the above technical solution, the linkage rod cooperates with the inner wall of the frame, so that the linkage rod slides horizontally in the connecting seat, thereby driving the scraper strip to slide on the connecting seat.

[0011] By adopting the above technical solution, there is a depth difference between the lower end of the first slide groove and the second slide groove, so that when moving downward, the telescopic cylinder moves from the first slide groove to the second slide groove, and when the connecting seat moves upward again, the linkage rod moves relatively in the horizontal direction, the scraper strip can be separated from the observation window, and moves from the upper end of the second slide groove to the first slide groove, and this is repeated.

[0012] Optionally, the telescopic cylinder is slidably sleeved on a side wall of the linkage rod, and a second elastic member is provided between the telescopic cylinder and the linkage rod.

[0013] By adopting the above technical solution, under the action of the second elastic member, the telescopic cylinder abuts against the inner wall of the first sliding groove or the second sliding groove, thereby facilitating the movement of the linkage rod.

[0016] Optionally, the guide member is a guide rod disposed in the frame, and the guide rod slides through the connecting seat.

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1-6 This application is described in further detail.

[0030] The present application embodiment discloses a chlorine liquefaction device. Figure 1 The chlorine liquefaction device includes a treatment box 1 and an observation window 2 arranged on the side wall of the treatment box 1. A connecting pipe is installed at the upper end of the interior of the treatment box 1 for connecting with the liquefaction spiral pipe in the treatment box 1. This is a prior art and will not be described in detail. The treatment box 1 can be a cylindrical structure or a square box structure. In this embodiment, the cylindrical shape is taken as an example for explanation.

[0031] Reference Figure 1 and Figure 2During operation, the observation window 2 is often covered with mist, etc., which makes it inconvenient to observe the internal working conditions. A wiping structure 3 is also installed in the processing box 1, and the wiping structure 3 is used to clean the inside of the observation window 2. The wiping structure 3 includes a frame 31 fixed to the inner wall of the processing box 1, a scraper 32 sliding up and down on the frame 31, and a driving source 33 installed on the frame 31. The frame 31 corresponds to the position of the observation window 2, and the driving source 33 drives the scraper 32 to move up and down, and cleans the observation window 2 through the scraper 32. The frame 31 is fixed to the inner wall of the processing box 1 by setting legs at the four corners.

[0032] Reference Figure 2 and Figure 3 The scraper 32 includes a connection seat 321 slidably mounted in the frame 31, and a scraper strip 322 horizontally slidably mounted on the connection seat 321. The connection seat 321 slides up and down in the frame 31, and the driving source 33 is connected to the connection seat 321 and drives the connection seat 321 to move up and down. The scraper strip 322 is slidably mounted on the side of the connection seat 321 close to the observation window 2, and the scraper strip 322 slides in the horizontal direction. When the connection seat 321 moves downward, the scraper strip 322 abuts against the observation window 2, thereby scraping the oil droplets and other substances on the observation window 2 downward. When the driving source 33 drives the connection seat 321 to move upward, the scraper strip 322 moves in a direction away from the observation window 2, so that the scraper strip 322 and the observation window 2 are separated. During the upward movement, the scraper strip 322 will no longer bring the oil droplets back to the observation window 2, thereby greatly improving the cleaning effect of the observation window 2.

[0033] Reference Figure 4 The connection seat 321 is an internal hollow structure and penetrates to both ends of the connection seat 321. The two ends of the scraper strip 322 are fixed with sliding rods 4. The sliding rods 4 slide through the side wall of the connection seat 321 and extend into the connection seat 321. The ends of the sliding rods 4 are fixed with linkage rods 5. The two sliding rods 4 are fixed to the side walls of the linkage rods 5. The sliding rods 4 are installed with a first elastic member 6 on part of the outer wall of the inner cavity of the connection seat 321. The first elastic member 6 is a spring. The spring is sleeved on the side wall of the sliding rod 4. One end of the spring abuts against the side wall of the linkage rod 5, and the other end abuts against the inner wall of the connection seat 321. When the scraper strip 322 abuts against the observation window 2, the first elastic member 6 is in a compressed state. The end of the linkage rod 5 cooperates with the inner wall of the frame 31. When the connecting seat 321 moves downward, the linkage rod 5 squeezes the first elastic member 6 and makes the scraper strip 322 abut against the observation window 2; when the connecting seat 321 moves upward, the first elastic member 6 drives the linkage rod 5 to slide horizontally, and the first elastic member 6 is reset to separate the scraper strip 322 and the observation window 2.

[0034] Reference Figure 5The first slide groove 7 and the second slide groove 8 are formed on two opposite inner walls of the frame 31, and the first slide groove 7 and the second slide groove 8 extend in the vertical direction. The upper ends of the first slide groove 7 and the second slide groove 8 are connected, and the second slide groove 8 and the lower ends of the first slide groove 7 are connected. The first slide groove 7 is located between the second slide groove 8 and the observation window 2, that is, the distance between the first slide groove 7 and the observation window 2 is smaller than the distance between the second slide groove 8 and the observation window 2.

[0035] Combination Figure 4 The end of the linkage rod 5 is slidably sleeved with a telescopic cylinder 9, which slides along the length direction of the linkage rod 5. A guide groove block can be arranged between the telescopic cylinder 9 and the linkage rod 5 to cooperate with each other so that the telescopic cylinder 9 cannot rotate on the linkage rod 5. A second elastic member 10 is installed in the telescopic cylinder 9, and the second elastic member 10 is a spring. Under the elastic force of the spring, the end of the telescopic cylinder 9 abuts against the first slide groove 7 or the second slide groove 8. The depth of the lower end of the first slide groove 7 is less than the depth of the lower end of the second slide groove 8, so a step edge is formed between the lower ends of the first slide groove 7 and the second slide groove 8, and the step edge is inclined, so that the telescopic cylinder 9 enters the second slide groove 8 from the first slide groove 7, and the connecting seat 321 moves upward, and the telescopic cylinder 9 moves upward from the second slide groove 8. The depth of the upper end of the second chute 8 is less than that of the upper end of the first chute 7, thereby forming a step edge, which is inclined. The telescopic cylinder 9 moves upward, that is, it can move from the second chute 8 to the first chute 7, and the connecting seat 321 moves downward, and the telescopic cylinder 9 can move downward in the first chute 7. The telescopic cylinder 9 is in the first chute 7 or the second chute 8, so as to adjust the horizontal position of the scraper strip 322.

[0036] Reference Figure 2 and Figure 3 The driving source 33 includes a rotating rod 11 rotatably mounted on the upper and lower ends of the frame 31, and a first element 13 for driving one of the rotating rods 11 to rotate. Synchronous wheels 14 are coaxially fixed to the outer walls of both ends of the rotating rod 11, and a synchronous rope 15 is connected between the upper and lower synchronous wheels 14. When one of the rotating rods 11 rotates, the synchronous rope 15 can be synchronously driven to move. The synchronous rope 15 can also be replaced by a synchronous belt, a chain, etc. The connecting seat 321 is connected to the synchronous rope 15, and the movement of the synchronous rope 15 drives the movement of the connecting seat 321. Furthermore, in order to reduce the shaking of the connecting seat 321, a guide member 16 is installed in the frame 31. The guide member 16 is a guide rod vertically fixed in the frame 31. Two guide rods are provided, and they are respectively slid through the two ends of the connecting seat 321.

[0037] The first element 13 is a worm gear 132 fixed to the end of one of the rotating rods 11, and a motor 133 installed on the outer wall of the processing box 1. The motor 133 is preferably a forward and reverse motor 133. A worm 131 is fixed on the output shaft of the motor 133. The worm 131 and the worm gear 132 are meshed with each other, thereby driving the rotation of the rotating rod 11.

[0038] In a further embodiment, referring to Figure 3 and Figure 4 In order to improve the cleaning effect of the observation window 2, the upper surface of the scraper 322 is also slidably mounted with an abutment plate 17, and the side of the scraper 322 close to the observation window 2 can be provided with an elastic cleaning layer, such as rubber, so that the cleaning effect is better when the scraper 322 is pressed against the observation window 2. Figure 6 A third elastic member 18 is installed between the upper surface of the scraper bar 322 and the lower surface of the abutment plate 17. Under the action of the third elastic member 18, in the natural state, the abutment plate 17 has a portion that exceeds the side wall of the scraper bar 322. When the scraper bar 322 abuts against the observation window 2, the abutment plate 17 also abuts against the observation window 2, and the third elastic member 18 is compressed. The scraper bar 322 moves downward to scrape the grease downward, and the abutment plate 17 scrapes synchronously behind the scraper bar 322, thereby improving the cleaning effect. Preferably, the hardness of the abutment plate 17 is higher than the elastic layer portion of the side wall of the scraper bar 322.

[0039] The upper surface of the scraper strip 322 is provided with a sliding groove 21, and the lower surface of the abutment plate 17 is fixed with an extension block 22, which extends in the sliding groove 21 to achieve the sliding of the abutment plate 17. The third elastic member 18 is a spring and is installed in the sliding groove 21. One end of the third elastic member 18 is connected to the inner wall of the sliding groove 21, and the other end is connected to the side of the extension block 22 away from the observation window 2. In addition, the sliding groove 21 can be a dovetail or T-shaped groove, and the extension block 22 is a structure adapted to the sliding groove 21, so that the abutment plate 17 is not easy to be separated from the scraper strip 322.

[0040] When the scraper strip 322 is separated from the observation window 2, the contact plate 17 is also separated from the observation window 2, and the third elastic member 18 is reset, and the contact plate 17 has a portion that exceeds the side wall of the scraper strip 322. A first wedge block 19 is provided on the upper surface of the contact plate 17, and a second wedge block 20 is fixed on the top surface of the frame 31. When the connection seat 321 moves upward, the inclined surfaces of the first wedge block 19 and the second wedge block 20 can abut against each other, and under the action of the second wedge block 20, the first wedge block slides horizontally, that is, the contact plate 17 slides, the third elastic member 18 is compressed, and the contact surface of the inclined surfaces of the first wedge block 19 and the second wedge block 20 becomes larger and larger, and the grease on the lower surface of the contact plate 17 can be scraped away by the upper end of the scraper strip 322. When the connection seat 321 moves downward, the first wedge block 19 and the second wedge block 20 gradually separate, and the contact plate 17 is reset to a state where it exceeds the side wall of the scraper strip 322. In order to enable the scraper strip 322 to better scrape away the grease on the end portion of the lower surface of the abutment plate 17 , the scraper strip 322 is tilted on the side close to the observation window 2 , and the distance from the observation window 2 gradually increases from top to bottom.

[0041] The implementation principle of a chlorine liquefaction device in an embodiment of the present application is: the connecting seat 321 is driven to move up and down by the driving source 33, and when moving downward, the scraper bar 322 and the abutment plate 17 abut on the observation window 2, and when the connecting seat 321 moves upward, the scraper bar 322 and the abutment plate 17 are separated from the observation window 2, and when moving to the upper end, the abutment plate 17 can slide so that the end of the abutment plate 17 is received in the upper surface of the scraper bar 322.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
