Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of chemical production equipment, and specifically relates to a blending kettle for alkyl benzene sulfonate production. BACKGROUND

[0002] The blending kettle is an industrial equipment mainly used for mixing and preparing materials in chemical, pharmaceutical, food and other industries. It is usually made of stainless steel or other corrosion-resistant materials, has good sealing performance and temperature resistance, and can stir and heat materials under certain pressure and temperature. The blending kettle is provided with a stirring device to ensure uniform mixing of different components, and has functions such as temperature control and pressure monitoring to meet different process requirements. It is widely used in the blending of liquid, slurry and solid substances to improve production efficiency and product quality.

[0003] Chinese utility model patent 202322847252.5 specification discloses a blending kettle for chemical material production, which comprises a blending kettle body, a stirring device is arranged on the blending kettle body, a feeding hopper is communicated with the upper end of the blending kettle body, and a discharging pipe is communicated with the lower end of the blending kettle body; a cleaning assembly is arranged on the blending kettle body; the cleaning assembly comprises a fixed seat fixedly installed on the upper end of the blending kettle body. The blending kettle for chemical material production is provided with a cleaning assembly. By starting the driving part, the motor drives the gear to rotate. The meshing rack is driven by the gear to move the connecting column downward, synchronously drives the mounting seat, starts the water pump, and then the water pump pumps water through the water pipe and then discharges it into the cavity through the water inlet pipe. By arranging the spray head, the descending mounting seat flushes the inner wall of the blending kettle body and the stirring device. The movable mounting seat and the arranged scraper can scrape off the attached substances that cannot be cleaned on the inner wall of the blending kettle body.

[0004] During the production of alkyl benzene sulfonate, first, raw materials are prepared, and alkyl benzene reacts with fuming sulfuric acid or sulfur trioxide to produce alkyl benzene sulfonate. The temperature and sulfur trioxide gas concentration in the reaction need to be controlled. Then, the neutralization and blending stages are entered, which is the key link of the blending kettle. After the alkyl benzene sulfonate and sodium hydroxide solution react in the neutralization reactor, they enter the blending kettle. Thickening agent, pH regulator, functional additive and other additives are added in the blending kettle, and the temperature, stirring speed and solid content need to be controlled. Then, post-aging, spray drying and discharging are carried out. After the production is completed, various pollutants such as sulfonate crystal layer, polymer coking, silicate scale and composite scale are adhered to the inside of the blending kettle, so the blending kettle needs to be cleaned after use to avoid affecting the next use.

[0005] In the aforementioned patent, the scraping method of the scraper is inefficient and the scraper cannot rotate. If the scraper does not make good contact with the inner wall of the mixing vessel, there will be a phenomenon of missed scraping, resulting in the attachment not being cleaned properly. In addition, after the above patent is completed, water still remains in the nozzle. This water may drip during the chemical production process and affect the quality of the product. Therefore, a mixing vessel for the production of alkylbenzene sulfonates is proposed. Utility Model Content

[0006] The purpose of this invention is to provide a mixing kettle for the production of alkylbenzene sulfonates, so as to solve the problems of low efficiency of the scraping method of the scraper mentioned in the background art, and the easy occurrence of missed scraping, resulting in incomplete rinsing and residual water in the rinsing structure.

[0007] The technical solution of this utility model is:

[0008] The system includes a drive assembly, which comprises a mixing tank. A drive shaft is rotatably connected to the mixing tank. Multiple flushing components are fixedly connected to the drive shaft. Each flushing component includes multiple connecting pipes that communicate with the drive shaft. These multiple connecting pipes are connected to the same water storage box. Multiple valve pipes are fixedly connected inside the water storage box. C-shaped pipes are rotatably connected to the valve pipes. Corresponding water inlet holes are drilled on both the valve pipes and the C-shaped pipes. The same L-shaped scraper box is rotatably connected between the multiple C-shaped pipes. A spring plate is fixedly connected to the C-shaped pipe. A torsion spring is fixedly connected between the spring plate and the C-shaped pipe. Multiple high-pressure nozzles are fixedly connected to the L-shaped scraper box. An adjustment assembly is fixedly connected to the upper end of the mixing tank.

[0009] Furthermore, the drive assembly also includes a driven gear fixedly connected to the transmission shaft, a mounting bracket fixedly connected to the upper side wall of the mixing barrel, a drive gear meshing with the driven gear rotatably connected to the inner wall of the mounting bracket, a motor fixedly connected to the upper side wall of the mounting bracket, and the output end of the motor fixedly connected to the drive gear, an exhaust pipe connected to the upper end of the mixing barrel, the lower end of the L-shaped scraper box being set as an inclined structure, and the inclination angle of the lower end of the L-shaped scraper box matching the lower end of the mixing barrel, and multiple evenly distributed discharge ports being chiseled at the lower end of the L-shaped scraper box.

[0010] By setting up a drive component, when the motor starts, the motor drives the driven gear to rotate through the drive gear, which in turn drives the transmission shaft to rotate, thus realizing the mixed adjustment function of the transmission shaft. At the same time, the transmission shaft can also be used to achieve the cleaning function of supplying water and air.

[0011] Furthermore, the regulating component includes a valve housing rotatably connected to the upper end of the drive shaft, a valve core rotatably connected inside the valve housing, a water pipe connected to the left side wall of the valve housing, a hot air blower connected to the upper end of the valve housing, and multiple support columns fixedly connected between the valve housing and the mixing tank.

[0012] By setting up an adjustment component, the inner wall of the mixing tank can be rinsed and dried by rotating the valve core.

[0013] This invention provides an improved mixing vessel for the production of alkylbenzene sulfonates, which has the following improvements and advantages compared with the prior art:

[0014] Firstly, this utility model can improve the contact force between the L-shaped scraper box and the mixing barrel under the action of centrifugal force through the high-speed rotation of the drive shaft, so that the L-shaped scraper box can fully scrape off the adhering substances on the inner wall of the mixing barrel, and use the high-pressure nozzle to fully rinse the inner wall of the mixing barrel, thereby improving the rinsing efficiency of the mixing barrel.

[0015] Secondly, this utility model can perform a drying operation after rinsing by adjusting the components. This not only allows the inside of the mixing tank to dry quickly, but also allows the water in the rinsing components and drive shaft to be quickly discharged and evaporated by hot air, thus extending the service life of the rinsing structure.

[0027] The following will be combined with the appendix Figures 1 to 5 This utility model will be described in detail, and the technical solutions in the embodiments of this utility model will be clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0028] This invention provides, through improvements, a mixing vessel for the production of alkylbenzene sulfonates, such as... Figure 1 - Figure 5 As shown, the system includes a drive assembly 1, which includes a mixing tank 101. A drive shaft 102 is rotatably connected to the mixing tank 101. Multiple flushing assemblies 2 are fixedly connected to the drive shaft 102. Each flushing assembly 2 includes multiple connecting pipes 201 that communicate with the drive shaft 102. The multiple connecting pipes 201 are connected to the same water storage box 202. Multiple valve pipes 203 are fixedly connected inside the water storage box 202. C-shaped pipes 204 are rotatably connected to the valve pipes 203 via mechanical seals. Corresponding water inlet holes 205 are drilled on both the valve pipes 203 and the C-shaped pipes 204. The multiple C-shaped pipes 204 are rotatably connected to the same L-shaped scraper box 206 via mechanical seals. A spring plate 207 is fixedly connected to the C-shaped pipes 204. A torsion spring 208 is fixedly connected between the spring plate 207 and the C-shaped pipes 204. Multiple high-pressure nozzles 209 are fixedly connected to the L-shaped scraper box 206. An adjustment assembly 4 is fixedly connected to the upper end of the mixing tank 101.

[0029] In this embodiment: when the drive shaft 102 rotates at high speed, under the action of centrifugal force, multiple L-shaped scraper boxes 206 come into contact with the mixing tank 101, and at the same time drive the C-shaped tube 204 to rotate, so that the water inlet hole 205 on the valve tube 203 and the C-shaped tube 204 correspond. When water enters through the adjusting component 4, the water can pass through the C-shaped tube 204 and the L-shaped scraper boxes 206 and be sprayed from the high-pressure nozzle 209 to clean the inner wall of the mixing tank 101. At the same time, the L-shaped scraper boxes 206 can scrape off the attached substances on the inner wall of the mixing tank 101.

[0030] In the above embodiments, in order to drive the drive shaft 102 to rotate and also enable the drive shaft 102 to convey water for rinsing, the following method can be adopted:

[0031] The drive assembly 1 also includes a driven gear 103 fixedly connected to the drive shaft 102. A mounting bracket 104 is fixedly connected to the upper side wall of the mixing barrel 101. A drive gear 105 that meshes with the driven gear 103 is rotatably connected to the inner wall of the mounting bracket 104. A motor 106 is fixedly connected to the upper side wall of the mounting bracket 104, and the output end of the motor 106 is fixedly connected to the drive gear 105. An exhaust pipe 107 is connected to the upper end of the mixing barrel 101. The lower end of the L-shaped scraper box 206 is set as an inclined structure, and the inclination angle of the lower end of the L-shaped scraper box 206 matches the lower end of the mixing barrel 101. Multiple evenly distributed discharge ports 3 are chiseled at the lower end of the L-shaped scraper box 206.

[0032] In a preferred embodiment, when the motor 106 is started, the motor 106 drives the driven gear 103 to rotate through the driving gear 105, which in turn drives the transmission shaft 102 to rotate. At the same time, the transmission shaft 102 is connected to the valve housing 401 through a mechanical seal, so even when the transmission shaft 102 rotates at high speed, no leakage will occur.

[0033] refer to Figure 4 and Figure 5 In a preferred embodiment, the adjusting assembly 4 includes a valve housing 401 rotatably connected to the upper end of the drive shaft 102, and a handle rotatably connected to the side wall of the valve housing 401 and fixedly connected to the valve core 402. The handle is as follows: Figure 1 As shown, it can help the staff rotate the valve core 402. The valve core 402 is rotatably connected inside the valve housing 401. A water pipe 403 is connected to the left side wall of the valve housing 401. A hot air blower 404 is connected to the upper end of the valve housing 401. Multiple support columns 405 are fixedly connected between the valve housing 401 and the mixing tank 101.

[0034] It is worth noting that a T-shaped cavity is cut into the valve core 402, such as Figure 4 As shown, at this time, the drive shaft 102 is connected to the hot air blower 404. When the valve core 402 rotates to the left, the drive shaft 102 will be connected to the valve core 402.

[0035] In this embodiment, the connection between the drive shaft 102 and the valve core 402 or the hot air blower 404 can be adjusted by rotating the handle on the side wall of the valve housing 401, thereby achieving the adjustment function of water rinsing and drying.

[0036] Working principle: After the production of alkylbenzene sulfonate is completed, various contaminants adhere to the inside of the mixing tank, so the mixing tank 101 needs to be cleaned. When rinsing the mixing tank 101, firstly, the operator rotates the valve core 402 using the handle, connecting the drive shaft 102 to the water pipe 403. The water supply equipment then injects water into the water pipe 403. Next, the operator starts the motor 106, which drives the driven gear 103 to rotate via the drive gear 105. This drives the drive shaft 102 to rotate. When the drive shaft 102 rotates at high speed, under the action of centrifugal force... The process involves bringing multiple L-shaped scraper boxes 206 into contact with the mixing tank 101, allowing the L-shaped scraper boxes 206 to scrape off the deposits on the inner wall of the mixing tank 101. At the same time, the L-shaped scraper boxes 206 drive the C-shaped tube 204 to rotate, aligning the water inlet holes 205 on the valve tube 203 and the C-shaped tube 204. Water then enters the connecting pipe 201 through the drive shaft 102, then enters the water storage box 202 through the connecting pipe 201, and then enters the C-shaped tube 204 through the water inlet hole 205. After passing through the L-shaped scraper boxes 206 through the C-shaped tube 204, water is sprayed from the high-pressure nozzle 209 to rinse the deposits on the mixing tank 101.

[0037] After rinsing is completed and the rinsing water is drained, the operator can rotate the handle on the side wall of the valve housing 401 again to connect the drive shaft 102 with the hot air blower 404. At this time, the hot air generated by the hot air blower 404 will replace the water and be discharged from the high-pressure nozzle 209 to dry the mixing tank 101. During this process, the hot air can also discharge and evaporate the water in the rinsing component 2 through the exhaust pipe 107 under air pressure, avoiding water residue inside the rinsing component 2, which would affect the quality of subsequent chemical products.

[0038] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
