A first scraper is fixedly connected between adjacent top rods. The first scrapers are all located on the side of the adjacent top rods away from the stirring rods. The bottom end of the rotating rod is slidably embedded with a connecting rod. The bottom end of the connecting rod is located at the bottom end of the rotating rod and is fixedly connected with a second scraper. The top end of the rotating rod is located above the kettle body and is fixedly provided with a first motor. This patent can facilitate the cleaning of the inner wall of the kettle body, can conveniently adjust the position of the scraper, so as to avoid the scraper always contacting the inner wall of the kettle body, thereby effectively avoiding the wear of the scraper, and further effectively improving the service life of the scraper.

[0004] However, the current crystallization kettle has the following problems: When the crystallization kettle evaporates and crystallizes the raw materials, it is not convenient to adjust the crystallization rate of the raw materials, so it is not convenient to adjust the output of the raw material crystallization according to the production requirements. Therefore, it is necessary to design a crystallization kettle with adjustable crystallization rate that can adjust the crystallization rate of the raw materials according to the production requirements. Summary of the Invention

[0005] The purpose of the present invention is to provide a crystallization kettle with adjustable crystallization rate to solve the problems mentioned in the above background art.

[0006] To solve the above technical problems, the present invention provides the following technical solution: A crystallization kettle with adjustable crystallization rate, including a crystallization kettle main body. A heating device is arranged on the outer wall of the crystallization kettle main body. A filter box is fixed at the bottom of the crystallization kettle main body. A circulation pump is arranged between the bottom of the filter box and the crystallization kettle main body. A motor is fixed on the top of the crystallization kettle main body. A stirring rod is fixed at the bottom of the motor and is located inside the crystallization kettle main body. It also includes an adjusting device, a scraping device, an intercepting device and an anti-blocking device; Among them, the adjusting device includes an anti-adhesion component, an electric push rod, a stirring runner, a through-hole rod, a rib and a positioning rod. The electric push rod is fixed on the top of the main body of the crystallization kettle, and the telescopic end of the electric push rod penetrates through the top of the main body of the crystallization kettle. The positioning rod is fixed on the inner wall of the main body of the crystallization kettle. The through-hole rod is slidably installed inside the positioning rod and sleeved outside the stirring rod. The stirring runner is rotatably installed on the top of the through-hole rod. The rib is fixed on the outer wall of the stirring rod and penetrates through the bottom of the stirring runner. The anti-adhesion component is arranged above the stirring runner. The telescopic end of the electric push rod pushes the through-hole rod to drive the stirring runner to move downward below the liquid level of the raw material liquid. When the stirring rod rotates, the stirring rod drives the stirring runner to rotate through the rib. The stirring runner improves the stirring efficiency of the stirring rod for the raw material liquid, thereby improving the crystallization rate of the raw material liquid.

[0007] According to the above technical solution, the anti-adhesion component includes a U-shaped bump disk, a contact rod, a connecting plate and a U-shaped scraper. The U-shaped bump disk is fixed on the top of the inner wall of the main body of the crystallization kettle. The connecting plate is slidably installed on the outer wall of the stirring runner, and a spring is arranged between the connecting plate and the stirring runner. The contact rod is fixed on the top of the connecting plate. The U-shaped scraper is fixed on the side of the connecting plate away from the stirring runner and is slidably installed on the outer wall of the blade of the stirring runner. A bump is fixed on the bottom of the U-shaped bump disk, and the bump of the U-shaped bump disk is located on the movement track of the contact rod. At the same time, when the stirring runner is not in use, the stirring runner drives the contact rod to rotate through the connecting plate. The bump of the U-shaped bump disk pushes the contact rod to drive the connecting plate to move, and the connecting plate drives the U-shaped scraper to scrape off the crystals adhered to the blades of the stirring runner, so as to facilitate the next use of the stirring runner and reduce the maintenance frequency of workers.

[0008] According to the above technical solution, the wall scraping device includes a disturbing component, a fixing column, a cross bar and an L-shaped scraper. The fixing column is fixed at the bottom of the stirring rod. The cross bar is fixed on the outer wall of the fixing column. The L-shaped scraper is fixed at one end of the cross bar away from the fixing column. The L-shaped scraper is in contact with the inner wall of the main body of the crystallization kettle. The disturbing component is arranged above the cross bar. The stirring rod drives the fixing column to rotate, and the fixing column drives the L-shaped scraper to rotate through the cross bar. The L-shaped scraper scrapes off the crystals on the inner wall of the main body of the crystallization kettle, thereby avoiding the problem that crystals are generated on the inner wall of the main body of the crystallization kettle and affecting the subsequent crystallization of the raw material liquid.

At the same time, each time the through-hole rod is pushed and moved to the bottom of the crystallization kettle body by the electric push rod, the through-hole rod pushes the ball block to drive the spring plate to deform and swing, the spring plate drives the arc-shaped knocking rod to knock on the cross bar, and the cross bar drives the L-shaped scraper to vibrate, thereby improving the efficiency of the L-shaped scraper to scrape off the crystals on the inner wall of the crystallization kettle body.

[0011] According to the above technical scheme, the push-down assembly includes a sliding rod, several scraper rods and a resistance block. The sliding rod is slidably installed on the outer wall of the side of the mesh plate away from the fixed rod. Several scraper rods are fixed on the side of the sliding rod close to the fixed rod, and a spring sheet is provided between the scraper rod below and the mesh plate. The resistance block is fixed on the top of the sliding rod. The top of the resistance block is spherical, and the spherical part of the resistance block is located on the movement trajectory of the cross bar. At the same time, the cross bar pushes the spherical part of the resistance block to drive the sliding rod to move downward, and the sliding rod drives the scraper rod to move downward. The scraper rod pushes the crystals intercepted by the mesh plate downward, so that the crystals are accumulated at the discharge of the main body of the crystallization kettle, thereby improving the discharge efficiency of the crystals.

The cross rod pushes the convex ball of the pushing rod to drive the pushing rod to move, and the telescopic end of the telescopic rod drives the conical ring to move up and down. When the conical ring moves upward, the crystals will pass over the inclined surface of the conical ring to the bottom of the conical ring. When the conical ring moves downward, the conical ring pushes the crystals to be discharged downward along the discharge port of the crystallization kettle body, thereby further improving the efficiency of crystal discharge.

[0013] According to the above technical solution, the flipping assembly includes an L-shaped frame and a flipping ring, the L-shaped frame is fixed on the outer wall of the push rod, and the flipping ring is fixed on the side of the L-shaped frame away from the push rod.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are: (1) The present invention arranges an adjustment device so that the electric push rod, the through-hole rod and the positioning rod cooperate to drive the stirring wheel to move below the liquid surface of the raw material. When the stirring rod rotates, the stirring rod drives the stirring wheel to rotate through the convex strip. The stirring wheel improves the stirring efficiency of the stirring rod on the raw material liquid, thereby improving the crystallization rate of the raw material liquid. At the same time, when the stirring wheel is not in use, the electric push rod, the through-hole rod, the stirring wheel, the connecting plate, the abutment rod and the U-shaped convex block plate cooperate to drive the U-shaped scraper to scrape off the crystals adhered to the stirring wheel blades, thereby facilitating the next use of the stirring wheel and reducing the frequency of maintenance by workers.

[0015] (2) The present invention arranges a wall scraping device so that the stirring rod, the fixed column and the cross bar cooperate to drive the L-shaped scraper to scrape off the crystals on the inner wall of the crystallization kettle body, thereby avoiding the problem of crystallization on the inner wall of the crystallization kettle body and affecting the subsequent crystallization of the raw material liquid; at the same time, each time the through-hole rod is pushed and moved to the bottom of the crystallization kettle body by the electric push rod, the through-hole rod and the ball block cooperate to drive the spring plate to deform and swing, and the spring plate drives the arc-shaped knocking rod away from the cross bar. When the through-hole rod passes over the ball block, under the elastic force of the spring plate, the spring plate drives the arc-shaped knocking rod to knock on the cross bar, and the cross bar drives the L-shaped scraper to vibrate, thereby improving the efficiency of the L-shaped scraper to scrape off the crystals on the inner wall of the crystallization kettle body.

[0016] (3) The present invention sets an interception device so that the crystals generated by the evaporation of the raw material liquid will be intercepted by the screen plate, thereby facilitating the subsequent discharge of the crystals. At the same time, the cross bar, the abutment block, the slide bar and the screen plate cooperate to drive the scraper bar to move downward. The scraper bar pushes the crystals intercepted by the screen plate downward, so that the crystals are accumulated at the discharge point of the main body of the crystallization kettle, thereby improving the discharge efficiency of the crystals. (4) Through the setting of the anti-blocking device, the cross bar, the push rod and the telescopic rod cooperate to drive the conical ring to move up and down. When the conical ring moves upward, the crystal will cross the inclined surface of the conical ring to the lower part of the conical ring. When the conical ring moves downward, the conical ring pushes the crystal to be discharged downward along the discharge port of the main body of the crystallization kettle, thereby further improving the efficiency of crystal discharge. At the same time, the push rod drives the L-shaped frame to move up and down synchronously, and the L-shaped frame drives the turning ring to push the raw material liquid heated at the inner wall of the main body of the crystallization kettle towards the center of the main body of the crystallization kettle, so that the raw material liquid can be evenly heated, thereby indirectly improving the crystallization efficiency of the raw material liquid.
