Description

Technical Field

[0001] This utility model relates to the field of waste treatment, and more specifically, to a pretreatment device for dimethyldichlorosilane hydrolysis waste. Background Technology

[0002] Dimethyldichlorosilane hydrolysis waste is a waste product generated during organosilicon production, including emulsified hydrolysate waste, waste colloids, and siloxane-containing wastewater. It is characterized by high viscosity and high chlorine content, forming a "water-in-oil" state after cross-linking and emulsification, and also contains some cyclic compounds. Improper handling can easily cause equipment and pipeline blockages. Impurities and high chlorine content in the hydrolysis waste can affect the quality of subsequent products. Therefore, pretreatment of dimethyldichlorosilane hydrolysis waste is necessary. During the hydrolysis process, residues remain on the inner wall of the tank. Traditional hydrolysis waste pretreatment devices are not convenient for scraping off these residues. The pretreatment process for dimethyldichlorosilane hydrolysis waste... If the deposits on the inner wall of the tank are not scraped off in time, they will gradually accumulate, occupying the effective space inside the tank and affecting the flow and separation effect of waste in the device. The deposits on the inner wall of the tank may adsorb the reaction reagents or catalysts, reducing their effective concentration in the reaction system, thereby affecting the rate and extent of the reaction. At the same time, it is not convenient to discharge the separated liquid. In the pretreatment process, after oil-water separation through operations such as dissolution and neutralization, a lower layer of clear water and an upper layer of hydrolysate will be obtained. It is also not convenient to extract the separated liquid. If the separated liquid is not extracted in time, it will remain in the device, occupying space and affecting the subsequent separation operations, thus reducing the efficiency of the entire pretreatment process.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 As shown, a pretreatment device for dimethyldichlorosilane hydrolysis waste includes a barrel 1, a box 2 installed on the outside of the barrel 1, and a drive mechanism 3 for mixing materials is provided above the barrel 1.

[0023] It should be noted that: the barrel 1 serves as the main container for the pretreatment of hydrolysis waste, containing the reaction materials and providing space for mixing and reaction. The box 2 is installed on the outside of the barrel 1 to provide installation space for the separation mechanism 5, thereby realizing the liquid separation function.

[0024] The scraping mechanism 4 is located inside the barrel body 1. The scraping mechanism 4 includes a scraper 41 that slides on the inner wall of the barrel body 1. Multiple sets of scrapers 41 are provided. Two sets of connecting plates 42 are fixedly connected to one side of the scraper 41. An installation column 43 is fixedly connected between the two sets of connecting plates 42.

[0025] It should be noted that: the scraper 41 slides close to the inner wall of the barrel 1 to scrape off the sticky substances adhering to the barrel wall, preventing scaling from affecting the reaction efficiency and equipment life. The connecting plate 42 and the mounting column 43 respectively connect the scraper 41 and the mounting plate 8, so that the scraper 41 rotates synchronously with the rotating rod 32 to achieve circumferential wall scraping.

[0026] The separation mechanism 5 is located inside the box 2. The separation mechanism 5 includes a collection frame 51 installed inside the box 2. A float plate 52 is provided inside the box 2. Multiple sets of suspended balls 53 are installed on the inner wall of the float plate 52. A hose 54 is connected to the inner wall of the float plate 52.

[0027] It should be noted that: the collection frame 51 is designed to collect the mixed liquid drawn from the barrel 1, providing a place for subsequent separation. The float 52 and the suspension ball 53 are designed to utilize the principle of buoyancy, so that the float 52 always floats on the liquid surface and automatically adjusts its height according to the liquid level. One end of the hose 54 is connected to the float 52, and the other end is connected to the second water pump 14, which is used to extract the upper liquid such as oil phase or hydrolysis products.

[0028] The drive mechanism 3 includes a motor 31 mounted on the top of the barrel 1, and a rotating rod 32 is fixedly connected to the output end of the motor 31. A mounting bracket 6 for fixing the motor 31 is fixedly connected to the top of the barrel 1. Multiple sets of stirring blades 7 for stirring the raw materials are fixedly connected to the outside of the rotating rod 32. A mounting plate 8 is fixedly connected to the outside of the rotating rod 32, and the inner wall of the mounting plate 8 is fixedly connected to the outside of the mounting column 43.

[0029] It should be noted that: the motor 31 is designed to provide a power source to drive the rotating rod 32 to rotate. The rotating rod 32 is connected to the output end of the motor 31, which transmits power to the stirring blade 7 and the mounting plate 8, thereby driving the wall scraping mechanism 4 and the stirring components to rotate; the mounting frame 6 is designed to fix the motor 31 to ensure its stable operation and avoid vibration affecting the stirring effect. The stirring blade 7 rotates with the rotating rod 32 to fully stir the waste and treatment agent in the tank 1, promoting the uniform hydrolysis reaction. The mounting plate 8 is designed to connect the rotating rod 32 and the wall scraping mechanism 4 to transmit torque, so that the scraper 41 can rotate synchronously.

[0030] A fixed box 9 is fixedly connected to one side of the box body 2, and a drainage pipe 10 is connected to the inner wall of the barrel body 1; the end of the drainage pipe 10 away from the barrel body 1 is connected to a first water pump 11, and the outlet end of the first water pump 11 is connected to a drain pipe 12.

[0031] It should be noted that the fixed box 9 is installed on one side of the box body 2 to provide support and fixation for components such as the first water pump 11. Through the design of the diversion pipe 10, the first water pump 11 and the drain pipe 12, the pre-treated mixture in the barrel 1 can be transported to the collection frame 51 in the box body 2 through the diversion pipe 10 to realize the transfer of materials.

[0032] A counterweight rod 13 is installed on the inner wall of the collection box 51, and one end of the hose 54 is connected to a second water pump 14. The outlet end of the second water pump 14 is connected to an outlet pipe 15.

[0033] It should be noted that the counterweight rod 13 is installed on the inner wall of the collection frame 51 to increase the weight at the bottom and ensure that the float 52 remains stable when the liquid fluctuates, avoiding tilting or overturning. The design of the second water pump 14 and the outlet pipe 15 can draw the upper layer of liquid below the float 52 through the hose 54 and discharge it through the outlet pipe 15.

[0034] The inner wall of the barrel 1 is connected to a feed pipe 16 for adding the mixture, and the number of feed pipes 16 is set to four.

[0035] It should be noted that the feed pipe 16 injects hydrolyzed waste, water or other treatment agents into the barrel 1. Multiple sets of feed pipes 16 can achieve the zoning or simultaneous addition of different materials.

[0036] Working principle: First, dimethyldichlorosilane hydrolysis waste, along with neutralizing agent, solvent, and demineralized water, are added to tank 1 through feed pipe 16. Then, motor 31 is turned on, driving rotor 32 to rotate. The stirring blades 7 on rotor 32 stir and mix the raw materials in tank 1, promoting a thorough reaction between the waste and other additives. Simultaneously, the mounting plate 8 fixed to the outside of rotor 32 drives mounting column 43 to rotate. Mounting column 43, through connecting plate 42, drives scraper 41 to slide along the inner wall of tank 1, scraping away material adhering to the inner wall to prevent accumulation and ensure uniform reaction. After the reaction, the material enters the collection frame 51 inside the tank 2 through the drainage pipe 12 under the action of the first water pump 11 via the drainage pipe 10. Due to the complex composition of the hydrolysis waste, some substances have different densities and will stratify inside the tank 2. The float plate 52 floats on the liquid surface by relying on the internal suspension ball 53. The upper decomposed material is extracted by the hose 54 connected to the inner wall of the float plate 52 through the second water pump 14 and discharged through the water outlet pipe 15 for collection, thus achieving preliminary separation. At the same time, the hose 54 will descend with the float plate 52 during extraction. After extraction is completed, the second water pump 14 can be turned off.
