Description

Technical Field

[0001] The utility model relates to the technical field of calcium chloride flake production, in particular to an adjustable flake machine for calcium chloride production. Background Art

[0002] In the fields of fluorine chemical industry, pharmaceuticals, and organic synthesis, in addition to producing the main products, a large amount of by-product hydrochloric acid is usually produced. Due to the difference in the domestic demand for by-product hydrochloric acid and the amount produced by enterprises, the storage is prone to overstocking. The method of preparing calcium chloride flakes with by-product hydrochloric acid is usually used to solve the above problem.

[0003] For example, a Chinese utility model patent with patent number CN216321759U proposes a flaker with a scraper angle that can be precisely adjusted. The slider is driven to move backward by the rotation of the threaded rod, and the movement of the slider drives the mounting vertical plate to move backward, thereby adjusting the front and rear position of the scraper. The adjustment process is simple and convenient.

[0004] However, in the prior art, the distance between the blade of the flaker and the outer surface of the drum is generally controlled between 0.1mm and 0.15mm. If the distance between the blade and the drum is too close, the blade is likely to scratch the drum and wear itself seriously. If the distance between the blade and the drum is too far, the fabric film on the outer surface of the drum cannot be scraped clean. Therefore, it is particularly important to control the distance between the blade of the flaker and the outer surface of the drum.

[0005] How to reduce blade wear and ensure the scraping accuracy of the blade is a technical problem that needs to be solved urgently at this stage.

[0006] The information disclosed in this background technology section is only intended to deepen the understanding of the overall background technology of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. Utility Model Content

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0035] The utility model provides an adjustable flaker for calcium chloride production. The working principle of the utility model is to adjust the angle between the scraper assembly composed of a bottom plate, a blade platform rib plate and a scraper assembly and a drum on the flaker body within the range of 128° to 142°, so as to avoid material retention between the blade and the drum after the flaker has been running for a long time, thereby preventing the flaker from stopping normally, thereby achieving the purpose of reducing blade wear, ensuring the scraping accuracy of the blade and realizing long-term operation of the flaker.

[0036] The present invention will be further described in detail below with reference to the embodiments and specific implementation methods.

[0037] like Figures 1-4 As shown, an adjustable flaker for calcium chloride production includes a flaker body 1 and a plurality of scraper assemblies provided on the flaker body. The scraper assemblies are used to scrape the flaker body. The angle between the scraper assemblies and the flaker body is adjustable within a range of 128° to 142° under the action of an external force.

[0038] The flaker body is equipped with a cooling water inlet and outlet, a feed port, a steam inlet, a drain port, an overflow port, a bottom condensate outlet, an exhaust port, a temperature measuring port, a side condensate outlet, a sight glass, an inspection port, and a product discharge port. The design and operating pressures of the drum installed on the flaker body are 0.75 MPa and 0.5-0.6 MPa, respectively; the design external temperature of the drum is 130-150°C; and the operating temperature inside the drum is 25-45°C.

[0039] The scraper assembly includes a bottom plate 21 provided on the side wall of the flaker body, a knife platform rib 22 provided on the bottom plate, a scraper 23 provided on the knife platform rib, and an adjusting member for adjusting the angle of the scraper.

[0040] The scraper is mounted on the blade rib via an adjustment block 25, which is attached to the adjustment block via stainless steel bolts 26. An adjustment screw 27 is provided on the adjustment block, which drives the adjustment block back and forth along the blade rib. The top of the scraper is triangular in shape, with the inclined surface at the top.

[0041] The end of the tool platform rib is hinged to the end of the base plate, and the tool platform rib and the base plate are connected by a torsion spring. The tool platform rib is a pentagonal prism with an upper length of 180 mm, a lower length of 168 mm, and a chamfer of 56°.

[0042] The adjusting member includes an adjusting pressure block 241, a connecting rod 242 perpendicular to the bottom surface of the adjusting pressure block, an adjusting rod 243 hinged to the end of the connecting rod, an adjusting column 244 arranged at the end of the adjusting rod and a rotating handle 245 arranged at the end of the adjusting column; the adjusting column and the adjusting rod are both arranged horizontally; and the adjusting column and the adjusting rod are independent of each other; a column 246 is arranged on the frame of the sheet-forming machine body, and the column is provided with a through hole threadedly matched with the adjusting column. The adjusting column and the column are arranged vertically, and the adjusting rod remains stationary when the adjusting column rotates in the through hole.

[0043] The specific steps of using this utility model are as follows: Figures 1-4 As shown, the cooling water inlet and cooling water outlet are located on the upper part of the roller, on the same horizontal line, for the inlet and outlet of cooling water, ensuring that the internal temperature of the roller can meet the temperature requirements during operation when the roller rotates, and avoiding damage to the internal structure caused by excessive temperature. The feed port is used for feeding calcium chloride solution. After the roller rotates, the calcium chloride in the calcium solution can be adsorbed on the drum, and after steam drying, it is accumulated on the drum and sliced by a scraper blade and discharged through the product discharge port, while the solution condensate flows out through the bottom condensate outlet and the side condensate outlet.

[0044] The drum is driven by the motor to drive the roller to rotate through the belt, and then drives the drum to rotate, so that the calcium liquid gradually accumulates on the drum during the operation of the drum, which is conducive to slicing.

[0045] The blade ribs secure the scraper in place, while the adjustment blocks and screws precisely adjust the scraper angle and the drum's angle. The base plate, with its fixed angle, primarily controls the cutting angle between the scraper and the drum. The scraper is bolted to the upper adjustment block for easy removal and replacement. The blade ribs connect to the lower adjustment block. The screw, inserted diagonally between the upper adjustment blocks, adjusts the angle. The base plate is connected to the blade ribs.

[0046] Through the above method, the utility model provides an adjustable flaker for calcium chloride production, which avoids material retention between the blade and the drum after the flaker has been running for a long time, thereby preventing the flaker from stopping normally due to material retention between the blade and the drum, thereby achieving the purpose of reducing blade wear, ensuring the scraping accuracy of the blade and realizing long-term operation of the flaker, by adjusting the angle of the scraper assembly composed of the bottom plate, the blade rib and the scraper assembly and the drum on the flaker body within the range of 128° to 142°.

[0047] The above is only a preferred embodiment of the adjustable flaker for calcium chloride production disclosed in the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, which all fall within the scope of protection of the present invention.
