Description

Technical Field

[0001] This utility model relates to the field of crystallizer design technology, and in particular to a particle-grading OSLO crystallizer. Background Technology

[0002] The OSLO crystallizer utilizes the characteristic of a supersaturated solution continuously circulating from bottom to top within the crystallizer, ensuring full contact between the solution and the small crystals suspended within, promoting crystal growth. Once the crystals reach a certain particle size requirement, they settle to the bottom of the container under gravity and are output.

[0003] During long-term operation, OSLO evaporator crystallizers tend to accumulate a large amount of dirt on their inner walls and the outer walls of the connecting pipes. If this dirt is not cleaned in time, it will not only reduce product quality but may also clog the pipes and affect the normal operation of the equipment. However, since the separation box is a closed structure, conventional cleaning methods are difficult to operate, have limited cleaning effect and low efficiency. Therefore, a more effective cleaning solution is urgently needed.

[0004] The applicant's search revealed that patent number CN211097625U discloses an OSLO evaporator crystallizer, which uses a reciprocating waterproof motor, a spray ring, and spray holes. Water is pumped by a flushing water pump, and then sprayed through the spray ring to clean the inside of the separation tank. At the same time, the reciprocating waterproof motor starts and drives the spray ring to rotate, ensuring that the inside of the separation tank is completely flushed. This setup has a better cleaning effect and a better cleaning result.

[0005] However, the above solution does not clean the outer wall of the connecting pipe in the separation box, which is a certain shortcoming. Therefore, the applicant proposes a particle-grading OSLO crystallizer to solve this problem. Utility Model Content

[0006] This invention provides a particle-grading OSLO crystallizer, which solves the problems mentioned in the background.

[0007] To solve the above-mentioned technical problems, this utility model provides a particle classification OSLO crystallizer, including a separation box, an evaporation box installed on the top of the separation box, a connecting pipe installed at the bottom of the evaporation box extending into the separation box, a water spray cleaning assembly installed on the upper inner side of the separation box, and a pipe wall cleaning assembly installed on the connecting pipe. The pipe wall cleaning assembly includes an annular plate that slides up and down outside the connecting pipe, and a cleaning brush that fits against the outer wall of the connecting pipe is provided on the inner side of the annular plate. The annular plate operates synchronously to perform pipe wall cleaning when the water spray cleaning assembly is in operation.

[0008] Preferably, the water spray cleaning assembly includes a limiting frame fixed inside the separation box, an outer ring pipe rotatably mounted inside the limiting frame, the outer ring pipe connecting to an external water source, and a row of water outlets inclined towards the inner wall of the separation box at the bottom of the outer ring pipe. Two toothed gears mesh on the inner side of the outer ring pipe, one of the large gears connecting to the output shaft of a motor, and the motor mounted on the top of an annular support fixed inside the separation box.

[0009] Preferably, an inner ring pipe is installed on the inner side of the ring pipe through two connecting pipes. The inner ring pipe surrounds the lower end of the evaporator and is located above the connecting pipe. A row of water spray pipes is installed on the inner side of the inner ring pipe.

[0010] Preferably, the inner side of the ring plate is provided with a groove, and a pulley is rotatably installed inside the groove, the pulley sliding in a slide rail provided outside the connecting pipe.

[0011] Preferably, the cleaning brush on the inner side of the ring plate has two positions, one at the top and one at the bottom, respectively, located at the top and bottom ends of the pulley. The cleaning brush has a protruding part, which is embedded in the slide rail of the pulley.

[0012] Preferably, the top of the ring plate is connected to an anti-corrosion rope, which passes through a guide pulley group fixed on the outside of the evaporator for movement and limitation. The other end of the anti-corrosion rope is wound around the outside of a winding wheel, which is rotatably mounted at the bottom of the annular support.

[0013] Preferably, a small gear is fixed to the bottom of the winding reel, and the small gear meshes with a large gear.

[0014] Compared with related technologies, the particle-grading OSLO crystallizer provided by this utility model has the following beneficial effects:

[0015] This invention, through the design of a pipe wall cleaning component, allows for the cleaning of the outer wall of the connecting pipe by sliding up and down on the ring plate. Simultaneously, the inner and outer ring pipes rotate, and the water spray pipes on their inner sides continuously spray water to rinse different connecting pipes. Combined with the brushing action, the front, sides, and even hidden corners of the pipe wall are thoroughly cleaned. The water flow can penetrate into tiny crevices and crevices that the brush cannot reach, flushing out hidden dirt. The brush then further cleans these areas, ensuring that every part of the connecting pipe's outer wall is thoroughly cleaned. This avoids pipe blockage and corrosion caused by residual dirt, significantly improving the service life and operational stability of the connecting pipe. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Depend on Figures 1-5 As shown, the present invention includes a separation box 1, an evaporation box 11 is installed on the top of the separation box 1, a connecting pipe 12 installed at the bottom of the evaporation box 11 extends into the interior of the separation box 1, a water spray cleaning component 2 is installed on the upper inner side of the separation box 1, and a pipe wall cleaning component 3 is installed on the connecting pipe 12.

[0024] The water spray cleaning assembly 2 includes a limiting frame 21 fixed inside the separation box 1. An outer ring pipe 22 is rotatably installed inside the limiting frame 21. The outer ring pipe 22 is connected to an external water source (for example, the outer ring pipe 22 is connected to an external water pump through a telescopic pipe, and the telescopic pipe passes through the annular support 13 to form a sliding mechanism, etc.). The bottom of the outer ring pipe 22 is provided with a row of water outlets inclined towards the inner wall of the separation box 1. Two toothed gears 23 are provided inside the outer ring pipe 22. One of the large gears 23 is connected to the output shaft of the motor 24. The motor 24 is installed on the top of the annular support 13 fixed inside the separation box 1. Note that the rotation angle of the outer ring pipe 22 is between 45 degrees and 55 degrees.

[0025] The water spray cleaning component 2 is existing technology. It cleans the inner wall of the separator. During operation, an external water pump introduces water, which enters the outer ring pipe 22 and, under pressure, is rapidly sprayed out from a row of inclined outlets at the bottom of the outer ring pipe 22. These outlets, at a specific angle and evenly distributed, spray water in a fan shape onto the inner wall of the separator 1. The high-speed water jet acts like countless tiny water jets, powerfully washing away dirt and crystalline particles on the inner wall. Simultaneously, the motor 24 reciprocates, driving the large gear 23 to rotate. The gear meshes with the inner toothed channel of the outer ring pipe 22, allowing it to rotate between 45 and 55 degrees. This allows the sprayed water to cover a larger area of ​​the inner wall of the separator 1, avoiding cleaning dead zones. During the cleaning process, the water continuously impacts the inner wall, gradually peeling off the impurities attached to it. The peeled dirt flows down the inner wall with the water flow, eventually converging at the bottom of the separator 1. This is existing technology and is presented in the prior art document, and will not be elaborated upon here.

[0026] The pipe wall cleaning assembly 3 includes an annular plate 31 that slides up and down outside the connecting pipe 12. A cleaning brush 32, which fits against the outer wall of the connecting pipe 12, is provided on the inner side of the annular plate 31. The annular plate 31 operates synchronously with the water spray cleaning assembly 2 to clean the pipe wall. A groove is provided on the inner side of the annular plate 31, and a pulley 36 is rotatably mounted inside the groove. The pulley 36 slides in a track provided on the outer side of the connecting pipe 12. The cleaning brush 32 on the inner side of the annular plate 31 has two positions, one above the other, located on the pulley 36. At the upper and lower ends, the cleaning brush 32 has a raised part 37, which is embedded in the sliding track of the pulley 36. The top of the ring plate 31 is connected to the anti-corrosion rope 33. The anti-corrosion rope 33 passes through the guide pulley group 34 fixed on the outside of the evaporator 11 for movement and limitation. The other end of the anti-corrosion rope 33 is wound around the outside of the winding wheel 35. The winding wheel 35 is rotatably installed at the bottom of the annular support 13. A small gear 38 is fixed at the bottom of the winding wheel 35, and the small gear 38 meshes with the large gear 23.

[0027] Through the design of the pipe wall cleaning component 3, when the water spray cleaning component 2 is in operation, the motor 24 drives the large gear 23 to rotate. Since the small gear 38 meshes with the large gear 23, the large gear 23 will drive the small gear 38 to rotate, which in turn drives the winding wheel 35 to rotate. When the winding wheel 35 winds up the anti-corrosion rope 33, the anti-corrosion rope 33, under the guidance of the guide pulley group 34, pulls the ring plate 31 to slide upward along the connecting pipe 12. At this time, the cleaning brushes 32 at the upper and lower parts of the inner side of the ring plate 31 move together with the ring plate 31 to thoroughly clean the outer wall of the connecting pipe 12. The pulley 36 slides in the track outside the connecting pipe 12, ensuring the smooth and stable movement of the ring plate 31. The protruding part 37 of the cleaning brush 32 is embedded in the track, further enhancing the fit between the cleaning brush 32 and the connecting pipe 12 and improving the cleaning effect. When the motor 24 rotates in the opposite direction, the winding wheel 35 releases the anti-corrosion rope 33, and the ring plate 31 slides downward under the action of gravity, cleaning the outer wall of the connecting pipe 12 again. This process is repeated to achieve continuous and efficient cleaning of the outer wall of the connecting pipe 12.

[0028] An inner ring pipe 26 is installed inside the outer ring pipe 22 through two connecting pipes 25. The inner ring pipe 26 surrounds the lower end of the evaporator 11 and is located above the connecting pipe 12. A row of water spray pipes 27 is installed inside the inner ring pipe 26 (note that the water flow velocity sprayed through the water spray pipes 27 is relatively low, which will not have a significant impact on the anti-corrosion rope 33, and plays an auxiliary role in conjunction with the brush).

[0029] Furthermore, during the up-and-down sliding of the ring plate 31, the inner ring pipe 26 rotates together with the outer ring pipe 22, and a row of water spray pipes 27 on its inner side simultaneously sprays water. Although the flow rate of these water streams is relatively low (mainly to allow the sprayed water to flow from the lower end of the evaporator 11 to the connecting pipe 12), it can cooperate with the cleaning action of the cleaning brush 32. When the cleaning brush 32 brushes over the outer wall of the connecting pipe 12, the water sprayed from the water spray pipes 27 can promptly wash away the dirt brushed off by the cleaning brush 32, preventing the dirt from re-adhering to the connecting pipe 12. Moreover, the water flow can also rinse the cleaning brush 32 to a certain extent, keeping the cleaning brush 32 clean and extending its service life.
