Description

Technical Field

[0001] This utility model relates to a citric acid gypsum cleaning device, and pertains to the field of gypsum processing technology. Background Technology

[0002] The neutralization process of citric acid often uses calcium carbonate for neutralization, which produces citric acid gypsum. However, citric acid gypsum contains various impurities such as hydrochloric acid insolubles, calcium oxalate, citric acid, and sugar compounds. These impurities will generate a lot of organic foam during the cleaning process. If the foam is not cleaned in time, it will lead to a decrease in the strength of the citric acid gypsum after cleaning and make it easy for bacteria to grow, making it unsuitable for use in the production of hemihydrate gypsum or related gypsum blocks. Summary of the Invention

[0003] The purpose of this invention is to design a cleaning device for removing organic foam during the cleaning process of citric acid gypsum.

[0004] This utility model includes a tank body, with a feed inlet at the top and a discharge outlet at the bottom. A drive motor is installed above the tank body, and a main shaft with a dispersing roller is installed inside the tank body and connected to the drive motor shaft. A material distributor connected to the feed inlet is wound around the main shaft. An overflow outlet is provided around the top of the tank body, and a set of foam scrapers corresponding to the upper position of the overflow outlet and arranged radially along the tank body are fixedly connected to the main shaft.

[0005] Furthermore, an inclined baffle plate is fixed on the main shaft below the fabric feeder, gradually moving outward from top to bottom.

[0006] Furthermore, the inclined baffle is conical in shape.

[0007] Furthermore, the upper end of the tank is open, and the overflow port is a set of grooves at the upper end of the tank.

[0008] Furthermore, a motor mount is fixed to the upper end of the tank, and the two ends of the motor mount are fixedly connected to the outer wall of the tank. The motor mounting part connected to the two ends of the motor mount is spaced apart from the upper end of the tank.

[0009] Furthermore, the feeder comprises an input pipe and a feed ring connected to the input pipe and surrounding the main shaft, with a set of feed openings provided along the feed ring; the further away from the connection point between the input pipe and the feed ring, the larger the opening size of the feed opening.

[0010] Furthermore, a set of dispersion blocks is fixed at the lower end of the main shaft, corresponding to the position of the discharge port, and is arranged circumferentially along the main shaft and protruding from the main shaft.

[0011] Furthermore, the dispersing roller is composed of a set of dispersing rods of varying lengths arranged circumferentially along the main shaft.

[0012] This invention employs a tank with an overflow outlet. When the citric acid gypsum solution to be cleaned is dispersed and cleaned by the dispersing rollers, the organic foam rises due to the buoyancy of the solution. Once the added solution reaches the overflow outlet, the foam is discharged through it. A foam scraper designed at the overflow outlet prevents foam residue. The inclined baffle in this invention diffuses the solution in all directions, preventing material agglomeration. Furthermore, a dispersion block is installed at the bottom of the tank's inner cavity. The dispersed citric acid gypsum solution settles at the bottom of the tank and is discharged. Adding the dispersion block prevents excessive settling of the citric acid gypsum, which could prevent discharge. Attached Figure Description

[0023] by Figure 1Define the up, down, left, right, front, and back directions in this embodiment.

[0024] As shown in the figure, this embodiment includes a tank 1 with an opening at the top. An overflow port 11 is provided at the top port, consisting of a set of grooves. In this embodiment, four grooves are provided at the top port of the tank 1 to collect and drain excess liquid from the tank 1. A motor base 4 is located above the tank 1. The left and right ends of the lower surface of the motor base 4 are welded to the outer surface of the top port of the tank 1, leaving a gap between them. A drive motor 5 is located above the motor base 4, and a main shaft 6 is connected to the shaft of the drive motor 5. The main shaft 6 passes through the motor base 4 and extends downwards, rotatably connecting to the bottom of the inner cavity of the tank 1. In this embodiment, the main shaft 6 adopts a hollow shaft structure, which can reduce the energy consumption of the drive motor 5.

[0025] A feed inlet 2 is provided at the upper part of the tank body 1. A distributor 7 is installed in the feed inlet 2. The distributor 7 includes an input pipe 8, which extends through the feed inlet 2 into the inner cavity of the tank body 1 and is connected to a distribution ring 9. The connection between the input pipe 8 and the feed inlet 2 is sealed by welding to prevent liquid leakage from the tank body 1. The distribution ring 9 is a hollow structure, sleeved around the outer circumference of the main shaft 6, and connected to the input pipe 8 by welding. A set of distribution ports 10 is provided on the lower surface of the distribution ring 9. In this embodiment, 11 distribution ports 10 are provided. The opening size of each distribution port 10 gradually increases from the connection between the input pipe 8 and the distribution ring 9. The further away from the connection, the larger the opening size of the distribution port 10. When the input pipe 8 delivers liquid to the distribution ring 9, the gradually increasing distribution port 10 can prevent the liquid from failing to flow out from the distribution port 10 far away from the input pipe 8, so that each distribution port 10 can deliver liquid.

[0026] A discharge port 3 is provided at the lower part of the tank body 1, which communicates with the inner cavity of the tank body 1. A peristaltic pump 16 is connected to its right end through a pipeline. During use, the output flow rate of the discharge port 3 can be controlled by the peristaltic pump 16. The peristaltic pump 16 in this utility model adopts the prior art, and will not be described in detail here.

[0027] A set of foam scrapers 12 is provided on the upper part of the main shaft 6. In this embodiment, it consists of two symmetrically distributed foam scrapers 12. The foam scrapers 12 are arranged radially along the tank body 1 and correspond to the position of the overflow port 11. They are fixedly installed on the outer surface of the main shaft 6 and can rotate with the main shaft 6 when in use.

[0028] An inclined baffle 13 is provided below the feeder 7. The inclined baffle 13 is conical and gradually extends outward from top to bottom. The upper end of the inclined baffle 13 is fixedly connected to the outer surface of the main shaft 6 and can rotate with the main shaft 6. When in use, it can spread the liquid material input by the feeder 7 to the surrounding area and prevent the liquid material from accumulating and clumping.

[0029] A set of dispersing rollers 14 is provided below the inclined baffle 13. In this embodiment, the dispersing rollers 14 are composed of two sets of dispersing rods 17 of different lengths. Each set of dispersing rods 17 is symmetrically arranged along the circumference of the main shaft 6 and is fixedly installed on the outer surface of the main shaft 6. It can rotate with the main shaft 6 and can disperse and clean the liquid material during use, so that the impurities in the liquid material form organic foam.

[0030] A set of dispersing blocks 15 is provided below the dispersing roller 14. In this embodiment, four dispersing blocks 15 are evenly distributed around the main shaft 6. Each dispersing block 15 is in the shape of an inverted triangle, fixedly installed on the outer surface of the main shaft 6 and protruding from the main shaft 6. When in use, it can rotate with the main shaft 6, which can avoid the phenomenon that the citric acid gypsum in the cleaning liquid settles excessively at the bottom of the tank 1 and cannot be discharged.

[0031] In use, the drive motor 5 is first started to make the main shaft 6 start to rotate, the peristaltic pump 16 is turned on, and the output flow rate of the discharge port 3 is adjusted to be less than the input flow rate of the cloth port 10. After completion, the citric acid gypsum liquid mixed with water is delivered to the input pipe 8. After the liquid is discharged from the cloth port 10, it spreads to the surroundings through the inclined baffle 13. Then, the liquid is dispersed and cleaned by the dispersing roller 14. During the dispersing process, the impurities in the liquid will form organic foam. Under the action of buoyancy, the organic foam will rise to the level of the liquid. As the liquid is input, when the level of the liquid reaches the overflow port 11, the organic foam is pushed by the foam scraper 12 and discharged with the water flow at the overflow port 11. The cleaned citric acid gypsum liquid is transported to the subsequent process by the peristaltic pump 16.
