Description

Technical Field

[0001] This utility model relates to the field of caustic soda crystallizer technology, and in particular to an improved liquid-to-solid caustic soda crystallizer. Background Technology

[0002] The caustic soda crystallizer is a key piece of equipment used for the concentration and crystallization of sodium hydroxide solution, and is mainly used to produce solid caustic soda products from caustic soda solution.

[0003] In the existing technology, the inner wall of the liquid-to-solid caustic soda crystallizer is often cleaned by a simple scraper. However, the scraper will be damaged when it comes into contact with the deposits during cleaning. When the scraper is severely damaged, the entire scraper mechanism needs to be replaced, which increases the replacement cost. Summary of the Invention

[0004] The purpose of this invention is to provide an improved liquid-to-solid caustic soda crystallizer to solve the problem mentioned in the background art that the scraper will be damaged after contacting the deposits when cleaning the inner wall of the crystallizer. When the scraper is severely damaged, the entire scraper mechanism needs to be replaced, which increases the replacement cost.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: It includes a crystallizer mechanism, comprising a crystallizing vessel, an embedded coil, a drive motor, a rotating rod, and a stirring head. The crystallizer mechanism has a scraper connecting assembly inside, comprising a connecting plate, a moving block, a limiting block, and a connecting spring. A scraper mechanism is provided on one side of the scraper connecting assembly, comprising a scraper frame, a moving groove, a limiting groove, a mounting groove, a first threaded groove, a threaded block, a knob, a mounting plate, a second threaded groove, and a cleaning scraper.

[0006] In a preferred embodiment, the inner wall of the crystallization vessel is fixedly connected to the outer wall of the embedded coil, the top of the crystallization vessel is fixedly connected to the bottom of the housing of the drive motor, the output end of the drive motor is fixedly connected to the top end of the rotating rod through a coupling, and the bottom end of the rotating rod is fixedly connected to the top of the stirring head.

[0007] In a preferred embodiment, one side of the rotating rod is fixedly connected to one side of the connecting plate, the connecting plate being located inside the crystallization vessel, and the other side of the connecting plate being fixedly connected to one side of the moving block.

[0008] In a preferred embodiment, both the upper and lower sides of the movable block are fixedly connected to one side of the limiting block, and the side of the movable block away from the connecting plate is fixedly connected to one end of the connecting spring.

[0009] In a preferred embodiment, a scraper frame is provided on the side of the connecting plate away from the rotating rod, and a moving groove is formed inside one side of the scraper frame, with the inner wall of the moving groove being movably connected to the outer wall of the moving block.

[0010] In a preferred embodiment, limiting grooves are provided on both the upper and lower sides of the movable groove, and the inner wall of the limiting groove is movably connected to the outer wall of the limiting block, and the other end of the connecting spring is fixedly connected to the inner wall of the movable groove.

[0011] In a preferred embodiment, an installation groove is provided inside the other side of the scraper frame, and a first threaded groove is provided on one side of the inner wall of the installation groove. The inner wall of the first threaded groove is threadedly connected to the outer wall of the threaded block, and one end of the threaded block is fixedly connected to one side of the knob.

[0012] In a preferred embodiment, the inner wall of the mounting groove is movably connected to the outer wall of the mounting plate, the mounting plate has a second threaded groove inside, and the inner wall of the second threaded groove is threadedly connected to the outer wall of the threaded block. One side of the mounting plate is fixedly connected to one side of the cleaning scraper.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, when the cleaning scraper is damaged and needs to be replaced, rotating the knob drives the threaded block to rotate, so that the threaded block moves away from the inside of the second threaded groove and the first threaded groove, so that the mounting plate is freed from the limited state, and then the mounting plate can be taken out from the inside of the mounting groove, thereby replacing the cleaning scraper. This facilitates the individual replacement of the cleaning scraper, gets rid of the traditional whole replacement method, and reduces the replacement cost.

[0015] In this invention, during cleaning, the spring force of the connecting spring drives the scraper frame to squeeze the inner wall of the crystallization vessel. At the same time, the moving block and the limiting block move inside the moving groove and the limiting groove, respectively. As the scraper frame moves, it drives the cleaning scraper to squeeze the inner wall of the crystallization vessel. By squeezing the inner wall of the crystallization vessel, the scraping force is increased, thereby increasing the cleaning effect. Attached Figure Description

[0027] Specifically, the stability of the scraper frame 301 is ensured by the setting of the connecting plate 201.

[0028] In one embodiment, both the upper and lower sides of the movable block 202 are fixedly connected to one side of the limiting block 203, and the side of the movable block 202 away from the connecting plate 201 is fixedly connected to one end of the connecting spring 204.

[0029] Specifically: the elastic force of the connecting spring 204 drives the scraper frame 301 to squeeze the inner wall of the crystallization vessel 101.

[0030] In one embodiment, a scraper frame 301 is provided on the side of the connecting plate 201 away from the rotating rod 104. A moving groove 302 is provided inside one side of the scraper frame 301, and the inner wall of the moving groove 302 is movably connected to the outer wall of the moving block 202.

[0031] Specifically: As the scraper frame 301 moves, it drives the cleaning scraper 310 to squeeze the inner wall of the crystallization vessel 101. By squeezing the inner wall of the crystallization vessel 101, the scraping force is increased.

[0032] In one embodiment, limiting grooves 303 are provided on both the upper and lower sides of the moving groove 302, and the inner wall of the limiting groove 303 is movably connected to the outer wall of the limiting block 203, and the other end of the connecting spring 204 is fixedly connected to the inner wall of the moving groove 302.

[0038] Working principle: The drive motor 103 is started, driving the rotating rod 104 to rotate. The rotation of the rotating rod 104 drives the stirring head 105 to rotate, simultaneously driving the connecting plate 201 to rotate. The rotation of the connecting plate 201 drives the scraper frame 301 and the cleaning scraper 310 to rotate. The cleaning scraper 310 scrapes and cleans the crystallized deposits on the inner wall of the crystallization vessel 101. During cleaning, the elastic force of the connecting spring 204 drives the scraper frame 301 to press against the inner wall of the crystallization vessel 101. Simultaneously, the moving block 202 and the limiting block 203... The scraper frame 301 moves within the moving groove 302 and the limiting groove 303. As the scraper frame 301 moves, it drives the cleaning scraper 310 to press against the inner wall of the crystallization vessel 101. When the cleaning scraper 310 is damaged and needs to be replaced, the knob 307 is rotated to drive the threaded block 306 to rotate, so that the threaded block 306 moves away from the inside of the second threaded groove 309 and the first threaded groove 305, so that the mounting plate 308 is freed from the limiting state, and then the mounting plate 308 is taken out from the inside of the mounting groove 304, thereby replacing the cleaning scraper 310.
