Description

Technical Field

[0001] This utility model relates to the field of cleaning device technology, and more specifically, to a cleaning device for the inner wall of a chemical reaction vessel. Background Technology

[0002] The internal wall cleaning device of a chemical reactor refers to a mechanical device specifically designed for cleaning the internal surface of reactors used in chemical production. Chemical reactors are core equipment used for chemical reactions in industries such as chemical, pharmaceutical, and food. After repeated use, their internal walls are prone to residues of reactants, byproducts, or coking substances. These residues not only affect the purity and quality of subsequent products, but may also cause cross-contamination, reduce heat transfer efficiency, and even pose safety hazards.

[0003] However, the cleaning devices for the inner walls of chemical reactors are difficult to effectively remove strongly adhesive coking or solidified residues, especially in the bottom and corner areas of the reactor, where cleaning dead zones are easily formed. At the same time, after cleaning, a large amount of water often remains inside the reactor, which can easily affect the subsequent reaction.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes an inner wall cleaning device suitable for chemical reaction vessels, so as to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A device for cleaning the inner wall of a chemical reactor includes a mounting base, on which a cleaning mechanism is mounted. The cleaning mechanism includes a hollow motor mounted on the mounting base, a hollow cleaning rod at one end of the hollow motor, a cleaning scraper at one end of the hollow cleaning rod, and cleaning spray heads evenly distributed on the surface of the hollow cleaning rod. The other end of the hollow motor is connected to a delivery pipe via a rotary joint. Control valves are installed at both ends of the delivery pipe. One end of one control valve is connected to a cleaning liquid input pipe, and the other end of the control valve is connected to an auxiliary mechanism.

[0008] Furthermore, in order to better assist in drying the interior of the clean reaction vessel, the auxiliary mechanism includes an adsorption pump connected to one end of a control valve, an auxiliary box at one end of the adsorption pump, an auxiliary trough on one side of the auxiliary box, a filter screen inside the auxiliary trough, and an activated carbon screen and an electric heating wire inside the auxiliary box.

[0009] Furthermore, in order to better clean the reactor and improve the sealing of the connection, the side of the auxiliary box is connected to the bottom of the mounting base of the reactor, and the top of the reactor is connected to the hollow motor through a sealed bearing.

[0010] Furthermore, in order to better place materials and facilitate subsequent maintenance, a placement opening is provided on the top of the reactor. A cover is hinged to the placement opening and the auxiliary box. The cover is locked to the auxiliary box and one side of the reactor.

[0011] Furthermore, in order to better monitor the pressure and temperature of the reactor during operation and cleaning, a pressure sensor, a temperature sensor, and an exhaust valve are installed on top of the reactor.

[0012] Furthermore, in order to better discharge the processed materials and cleaning liquid, the inside of the reactor is in contact with the side of the cleaning scraper, and a second control valve is installed at the bottom of the reactor, with one end of the control valve connected to an output pipe.

[0013] The beneficial effects of this utility model are as follows:

[0014] (1) The cleaning mechanism installed on the mounting base can scrape along the arc-shaped inner wall of the reactor without dead angles, which is beneficial to cover the bottom and corner areas of the reactor, avoid the formation of cleaning dead angles, and can also spray the cleaning liquid evenly to all parts of the reactor, further enhancing the cleaning effect on stubborn residues in the corners, ensuring that the cleaning mechanism can thoroughly clean the inner wall of the reactor. The auxiliary mechanism installed on the cleaning mechanism can not only efficiently recover and treat the cleaning waste liquid, but also quickly dry the inside of the reactor, avoiding the impact of residual moisture on subsequent reactions.

[0015] (2) By installing pressure sensors, temperature sensors and exhaust valves in the reactor, the cleaning process of the reactor can be monitored in real time, ensuring the safety and reliability of the cleaning operation. Attached Figure Description

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.

[0024] Example 1:

[0025] like Figures 1-3 As shown, an inner wall cleaning device for a chemical reactor according to an embodiment of the present invention includes a mounting base 1, a cleaning mechanism 2 on the mounting base 1, a hollow motor 201 on the mounting base 1, a hollow cleaning rod 202 at one end of the hollow motor 201, a cleaning scraper 203 at one end of the hollow cleaning rod 202, the cleaning scraper 203 being made of a flexible wear-resistant material (such as polyurethane, food-grade rubber, PTFE composite material, etc.), and cleaning spray heads 204 evenly distributed on the surface of the hollow cleaning rod 202. The other end of the hollow motor 201 is connected to a delivery pipe 205 via a rotary joint, and control valves 206 are provided at both ends of the delivery pipe 205. One end of one control valve 206 is connected to a cleaning liquid input pipe 207, and the other end of the control valve 206 is connected to an auxiliary mechanism 3.

[0026] Example 2:

[0027] like Figures 1-2 , Figure 4 As shown, according to an embodiment of the present invention, an inner wall cleaning device suitable for chemical reaction vessels is provided. An adsorption pump 301 is connected to one end of the auxiliary mechanism 3, which includes a control valve 206. An auxiliary box 302 is provided at one end of the adsorption pump 301. An auxiliary groove is provided on one side of the auxiliary box 302. A filter screen plate 303 is provided inside the auxiliary groove. An activated carbon mesh plate 304 and an electric heating wire 305 are provided inside the auxiliary box 302.

[0028] The side of the auxiliary box 302 is connected to the bottom of the mounting base 1 and the reactor 4 is connected to the top of the hollow motor 201 through a sealed bearing. The reactor 4 has a placement opening on the top and a cover 5 is hinged to the auxiliary box 302. The cover 5 and the auxiliary box 302 and the reactor 4 are provided with a latch 6.

[0029] A pressure sensor 7, a temperature sensor 8, and an exhaust valve 9 are respectively installed above the reactor 4. One end of the exhaust valve 9 is connected to a centralized waste gas treatment device (not shown in the figure) for treating cleaning waste gas. The interior of the reactor 4 is in contact with the side of the cleaning scraper 203. A control valve 2 10 is installed below the reactor 4. One end of the control valve 2 10 is connected to an output pipe 11 for conveying the processed materials and discharging the cleaning waste liquid. The output pipe 11 can be a three-way pipe in actual use. One end of the three-way pipe is connected to a centralized cleaning waste liquid treatment device (not shown in the figure) for treating the cleaning waste liquid.

[0030] Control valve 2 10, pressure sensor 7, temperature sensor 8, exhaust valve 9, electric heating wire 305, control valve 1 206, and hollow motor 201 are electrically connected to a controller (not shown in the figure) in actual use. The controller is a PLC (programmable logic controller) or a microcontroller. The specific working control program of the controller is written and set according to the actual situation, which is conducive to the precise control of the electrically connected electrical components. The above structure is electrically connected to an external power supply in actual use.

[0031] Control valve 2 (10), pressure sensor (7), temperature sensor (8), exhaust valve (9), latch (6), electric heating wire (305), control valve 1 (206), hollow motor (201), filter screen (303), and activated carbon screen (304) are existing technologies and will not be described in detail. The specific models and specifications need to be selected and determined according to the actual specifications of the device.

[0032] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0033] In summary, with the help of the above-mentioned technical solution of this utility model, when cleaning is required, the cleaning liquid enters the delivery pipe 205 through the cleaning liquid inlet pipe 207, and after the flow rate is regulated by one of the control valves 206, it is injected into the internal channel of the hollow cleaning rod 202. Then, the hollow motor 201 is powered on and runs, driving the hollow cleaning rod 202 to rotate. Since the cleaning scraper 203 is installed at the end of the hollow cleaning rod 202, the cleaning scraper 203 keeps in contact with the inner wall of the reaction vessel 4. During the rotation, the stubborn residues attached to the inner wall are physically scraped off, achieving preliminary cleaning.

[0034] As the hollow cleaning rod 202 continues to rotate, the cleaning liquid is evenly sprayed from multiple cleaning spray heads 204 distributed on the surface of the hollow cleaning rod 202, directly acting on the inner wall surface of the reactor 4, mixing with the scraped and loosened dirt, enhancing the cleaning effect, and the waste liquid formed by the sprayed cleaning liquid and the residue gathers to the bottom of the reactor 4 under the action of gravity.

[0035] After cleaning, the cleaning waste liquid accumulated at the bottom of the reactor 4 is discharged through the output pipe 11 by opening the control valve 10 and transported to the waste liquid centralized treatment device for subsequent environmental protection treatment. During the cleaning process, the pressure sensor 7 and the temperature sensor 8 monitor the pressure and temperature changes inside the reactor 4 in real time and feed the data back to the controller to ensure that the cleaning environment is within a safe and controllable range. If the internal pressure is too high, the exhaust valve 9 will open automatically to discharge excess gas and prevent safety hazards.

[0036] After the cleaning stage is completed, another control valve 206 switches the flow direction, causing the adsorption pump 301 to start. Through negative pressure, the residual moisture and volatile components in the reactor 4 are drawn into the auxiliary box 302. The gas first passes through the filter screen 303 in the auxiliary tank to remove particulate impurities, and then passes through the activated carbon screen 304 to adsorb harmful organic components, thus purifying the waste gas. At the same time, the electric heating wire 305 is energized to heat the airflow entering the auxiliary box 302, improving the drying efficiency and promoting rapid drying inside the reactor 4. The gas after purification and heating can be recycled or safely discharged.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
