Description

Technical Field

[0001] This application relates to the field of chemical production equipment, and more specifically, to a chemical product purification and decolorization device. Background Technology

[0002] In industries such as fine chemicals, pharmaceuticals, and food additives, many chemical products generate colored impurities during preparation, affecting their purity, appearance, and quality. Therefore, decolorization is a crucial step in the refining and purification of chemical products. Activated carbon adsorption is one of the most widely used decolorization technologies.

[0003] Current chemical product decolorization and purification methods in the industry include adsorption, which uses the porous structure or surface active sites of adsorbents (activated carbon, silica gel, alumina, etc.) to "capture" colored impurities, thereby achieving separation of products and impurities. Alternatively, a layer of activated carbon powder particles is placed on a filter screen, and the chemical product to be decolorized is poured onto the activated carbon powder particles. Decolorization is achieved as the chemical product permeates the activated carbon powder particles. However, this natural permeation method has low decolorization efficiency, and the chemical product needs to undergo multiple filtrations, resulting in low overall decolorization efficiency. Therefore, we propose a chemical product purification and decolorization device. Utility Model Content

[0004] To overcome the above shortcomings, this application provides a chemical product purification and decolorization device, which aims to improve the problem of low decolorization efficiency of existing activated carbon.

[0005] This application provides a chemical product purification and decolorization device, including a tank, a conical filter screen installed on the inner wall of the tank, a discharge component connected to the bottom of the conical filter screen, the discharge component penetrating the bottom of the tank, a stirring component installed on the top of the tank, the stirring component slidingly contacting the conical filter screen, and a spraying component for circulating chemical products connected to the side wall of the tank.

[0006] In one specific implementation, the discharge assembly includes a discharge pipe communicating with the bottom of the conical filter screen, the discharge pipe passing through the bottom of the tank, and a solenoid valve installed on the discharge pipe.

[0007] In one specific implementation, the stirring assembly includes a bracket fixedly installed on the top of the tank, a motor mounted on the bracket, a connecting shaft connected to the motor drive shaft, a connecting frame fixedly connected to the outer wall of the connecting shaft, a scraper fixedly installed at one end of the connecting frame, and the scraper being slidably in contact with the inner wall of the conical filter screen.

[0008] In one specific implementation, a soft scraper strip is installed on the edge of the scraper, and several baffle frames are fixedly installed on the outer wall of the connecting shaft.

[0009] In one specific implementation, a gas guide hood is fixedly installed on the top of the tank, and an inert gas inlet pipe is connected to the side wall of the gas guide hood. The connecting shaft rotates through the inert gas inlet pipe, and an exhaust hole is opened inside the connecting shaft. A through hole is opened on the side wall of the exhaust hole, and the through hole is located inside the gas guide hood.

[0010] In one specific implementation, the spraying assembly includes a water pump, the inlet end of which is connected to an inlet pipe and the outlet end of which are respectively connected to an outlet pipe. The inlet pipe is connected to the bottom of the side wall of the tank, and the outlet pipe passes through the top of the side wall of the tank, with its outlet end located above the conical filter screen.

[0011] In one specific implementation, the top of the tank is connected to a feed pipe, the top of the tank is provided with an exhaust port, and the bottom of its side wall is connected to a drain pipe.

[0012] In one specific implementation, an insulation sleeve is fixedly fitted on the outer wall of the tank, and the side wall of the insulation sleeve is connected to a heat transfer medium inlet and a heat transfer medium outlet.

[0013] The beneficial effects of this application are as follows: By installing a conical filter screen inside the tank, with the bottom of the conical filter screen connected to a discharge component, and activated carbon powder particles disposed on the conical filter screen, and a stirring component installed at the top of the tank, the stirring component is slidably contacted with the conical filter screen, thereby spraying the chemical product onto the activated carbon powder particles. At the same time, the stirring component stirs the activated carbon powder particles on the conical filter screen, thereby ensuring full contact between the chemical product and the activated carbon powder particles. In addition, the spraying component circulates the chemical product onto the activated carbon powder particles, thereby improving the decolorization rate and effect. Attached Figure Description

Detailed Implementation

[0017] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0018] Please see Figure 1-6 This application provides a chemical product purification and decolorization device, including a tank 10. A conical filter 20 is installed on the inner wall of the tank 10. Specifically, the tank 10 consists of a cylindrical body and a sealing cap. The connection structure between the sealing cap and the cylindrical body is existing technology. Activated carbon powder particles are placed on the conical filter 20. A discharge assembly 30 is connected to the bottom of the conical filter 20 and extends through the bottom of the tank 10. When the chemical product is decolorized, the discharge assembly 30 can be opened to allow the activated carbon powder particles to move downwards on the conical filter 20 into the discharge assembly 30, thereby discharging the activated carbon powder particles. A stirring assembly 40 is installed on the top of the tank 10 and slides in contact with the conical filter 20. A spraying assembly 50 for circulating chemical product spraying is connected to the side wall of the tank 10. Specifically, the spraying assembly 50 can circulate the chemical product onto the activated carbon powder particles, while the stirring assembly 40 continuously stirs the activated carbon powder particles, thereby significantly improving the decolorization efficiency and effect of the chemical product.

[0019] See Figure 3 and 6 The discharge assembly 30 includes a discharge pipe 310 that communicates with the bottom of the conical filter screen 20. The discharge pipe 310 passes through the bottom of the tank body 10. A solenoid valve 320 is installed on the discharge pipe 310. When set, the opening and closing of the discharge pipe 310 is controlled by the solenoid valve 320, so that the activated carbon powder particles on the conical filter screen 20 are discharged from the discharge pipe 310.

[0020] See Figure 3 , 46. The stirring assembly 40 includes a bracket 410 fixedly installed on the top of the tank 10. A motor 420 is mounted on the bracket 410. The motor 420's drive shaft is connected to a connecting shaft 430. Specifically, the motor 420 drives the connecting shaft 430 to rotate. A connecting frame 440 is fixedly connected to the outer wall of the connecting shaft 430. A scraper 450 is fixedly installed at one end of the connecting frame 440, so that the connecting shaft 430 drives the scraper 450 to rotate through the connecting frame 440. The scraper 450 is slidably contacted with the inner wall of the conical filter screen 20, so that the scraper 450 moves along the conical filter screen 20. The scraper 450 slides on the cone filter 20, and its shape is adapted to the arc-shaped interior of the cone filter 20. Furthermore, soft scraper strips are installed on the edge of the scraper 450, so that the scraper 450 and the soft scraper strips slide on the cone filter 20 to prevent the cone filter 20 from becoming clogged. Several baffle frames 460 are fixedly installed on the outer wall of the connecting shaft 430. The connecting shaft 430 drives the baffle frames 460 to rotate to stir the activated carbon powder particles on the cone filter 20, thereby improving the contact effect between the activated carbon powder particles and the chemical products and improving the decolorization efficiency.

[0021] See Figure 3-6 A gas guide hood 110 is fixedly installed on the top of the tank body 10. An inert gas inlet pipe 120 is connected to the side wall of the gas guide hood 110. When set up, the inert gas inlet pipe 120 is connected to the existing inert gas conveying device to realize the delivery of inert gas into the inert gas inlet pipe 120. The connecting shaft 430 rotates through the inert gas inlet pipe 120. An exhaust hole 470 is opened in the connecting shaft 430. A through hole 480 is opened on the side wall of the exhaust hole 470. The through hole 480 is located inside the gas guide hood 110. Then, the inert gas enters the exhaust hole 470 through the through hole 480, so that the inert gas is discharged into the tank body 10. The introduction of inert gas (such as nitrogen) can protect the decolorization process of easily oxidized materials.

[0022] See Figure 3 The spraying assembly 50 includes a water pump 510. The inlet and outlet ends of the water pump 510 are respectively connected to an inlet pipe 520 and an outlet pipe 530. The inlet pipe 520 is connected to the bottom of the side wall of the tank 10, and the outlet pipe 530 passes through the top of the side wall of the tank 10, with its outlet end located above the conical filter screen 20. In specific configuration, the water pump 510 operates, absorbs the chemical products at the bottom of the tank 10 through the inlet pipe 520, and then sprays them onto the activated carbon powder particles through the outlet pipe 530 to achieve the purpose of cyclic decolorization of the chemical products.

[0023] See Figure 2 and 3The top of the tank 10 is connected to a feed pipe, through which the chemical products to be decolorized and activated carbon powder particles can be fed into the tank 10. A sealing plate can be installed on the feed pipe, and an external water pipe can be introduced through the feed pipe for rinsing the conical filter screen 20 and cleaning the residual activated carbon powder particles on the conical filter screen 20. The top of the tank 10 has an exhaust port to discharge the gas inside the tank 10. The bottom of the side wall of the tank 10 is connected to a drain pipe. When installed, a valve is installed on the drain pipe to control the discharge of liquid. In addition, a heat insulation sleeve 60 is fixedly fitted on the outer wall of the tank 10. The side wall of the heat insulation sleeve 60 is connected to a heat transfer medium inlet and a heat transfer medium outlet, which can be connected to an external circulation system for heating or cooling the material inside the tank 10.

[0024] When this chemical product purification and decolorization device is in operation: Open the feed pipe and sequentially add activated carbon powder granules and the chemical product to be decolorized into the tank 10. Close the feed pipe, and the activated carbon powder granules remain on the conical filter screen 20. Start the motor 420 and the water pump 510, causing the motor 420 to drive the connecting shaft 430 to rotate. The connecting shaft 430, through the connecting frame 440, drives the scraper 450 to rotate, and the connecting shaft 430 also drives several baffle frames 460 to rotate. Meanwhile, the water pump 510 removes the chemical product from the bottom of the tank 10. The product is absorbed through the inlet pipe 520 and then fully sprayed onto the activated carbon powder particles through the outlet pipe 530. This process continuously decolorizes the chemical product while stirring, thereby improving decolorization efficiency and preventing clogging of the conical filter screen 20. During this process, inert protective gas can be added to the tank 10 through the inert gas inlet pipe 120. After the chemical product decolorization is completed, the decolorized chemical product can be discharged by opening the drain pipe, and the activated carbon powder particles can be discharged by opening the discharge pipe 310 controlled by the solenoid valve 320.

[0025] It should be noted that the specific models and specifications of the tank 10, motor 420 and water pump 510 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0026] The power supply and operating principle of the motor 420 and the water pump 510 are clear to those skilled in the art and will not be described in detail here.
