Description

Technical Field

[0001] The present invention relates to the technical field of chemical equipment cleaning, and more particularly to a high-efficiency cleaning device for a stainless steel reactor. Background Art

[0002] Stainless steel reactors are widely used in the chemical, pharmaceutical, and food industries for various chemical reactions and material mixing. Since reaction products, sediments, or dirt often remain inside the reactor, regular cleaning is an important part of ensuring the normal operation of the reactor and product quality.

[0003] When chemically cleaning the inner walls of reactors, an appropriate amount of chemical cleaning agent is typically injected into the reactor and allowed to soak to dissolve or loosen impurities adhering to the inner walls. Residues are then removed by rinsing with clean water or mechanical scraping (e.g., with a scraper). However, this method is limited in that, particularly for larger reactor inner walls, the probability of contact between the active ingredients in the chemical cleaning agent and impurities adhering to the inner walls is low, resulting in poor dissolution of the impurities and, consequently, low efficiency.

[0004] Therefore, an efficient cleaning device for stainless steel reactor is proposed. Summary of the Invention

[0005] In view of the problems existing in the prior art, the purpose of the present invention is to provide a high-efficiency cleaning device for stainless steel reactors, which can improve work efficiency.

[0006] To solve the above problems, the present invention adopts the following technical solutions.

[0007] A high-efficiency cleaning device for a stainless steel reactor, comprising a mounting frame;

[0008] A mounting tube is rotatably mounted on the mounting frame, and two mounting plates are symmetrically fixedly mounted on the mounting tube, and an elastic sleeve is commonly sheathed on the exterior of the two mounting plates;

[0009] Multiple electric telescopic rods are installed horizontally on each mounting plate, and a push rod is installed between the output ends of two electric telescopic rods located in the same vertical line;

[0010] A water suction valve is fixedly embedded on the top wall of the mounting plate located below the elastic sleeve, and the input end of the water suction valve passes through the elastic bottom wall and is connected to the outside world. A filter plate is provided in the elastic sleeve, and a drainage hole is provided on the side wall of the mounting pipe. A water inlet hole connected to the elastic sleeve is provided on the side wall of the mounting pipe. The water inlet hole is located above the filter plate, and a circulation mechanism for allowing the elastic sleeve to drain water through the drainage hole is provided on the mounting pipe.

[0011] Furthermore, the circulation mechanism includes a motor fixedly mounted on the mounting frame, the motor being used to drive the mounting tube to rotate;

[0012] A propeller is fixedly installed in the installation tube.

[0013] Furthermore, the output end of the electric telescopic rod passes through the elastic sleeve, and a sleeve is fixedly installed horizontally on the end face of the output end of the electric telescopic rod. An insertion rod is inserted horizontally in the end of the sleeve away from the electric telescopic rod. A first spring is installed between the insertion rod and the inner wall of the sleeve, and a scraper is installed on the end of the insertion rod away from the sleeve.

[0014] Furthermore, a groove is provided on the bottom wall of the filter plate, and stirring rods are evenly installed on the side wall of the mounting tube in a circumferential manner, and the stirring rods are located in the groove.

[0015] Furthermore, a diversion cavity is provided on the scraper, through holes are evenly provided on the side wall of the diversion cavity, a conduit is fixedly installed in the drainage hole, and one end of the conduit away from the drainage hole extends into the diversion cavity.

[0016] Furthermore, a guide rod is fixedly installed on the side wall of the through hole guide cavity, a striking rod is movably sleeved on the guide rod, and a second spring is installed between the striking rod and the side wall of the guide cavity.

[0017] Furthermore, the end surface of the striking rod away from the guide rod is a pointed end.

[0018] Furthermore, a rotating rod is vertically inserted into the top wall of the mounting tube, and the bottom end of the rotating rod extends into the mounting tube. A sealing plate is fixedly installed at the bottom end of the rotating rod, which is used to seal the drainage hole, and the top end of the rotating rod is fixedly connected to the mounting frame.

[0019] Furthermore, a driven gear is fixedly sleeved on the outer wall of the mounting tube, and a driving gear is fixedly mounted on the output end of the motor, and the driving gear is meshed with the driven gear.

[0020] Furthermore, a sliding groove is vertically opened on the side wall of the scraper close to the electric telescopic rod, and the output end of the electric telescopic rod is slidably installed in the sliding groove.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] (1) This solution can reduce the distance between the elastic sleeve and the inner wall of the reactor through the mutual cooperation of the mounting plate, the electric telescopic rod, the push rod, and the elastic sleeve, thereby reducing the space volume between the reactor and the elastic sleeve. Therefore, when the detergent is subsequently injected, it plays a role in saving the consumption of detergent. At the same time, the space volume where the detergent is located is smaller, which increases the probability of the effective ingredients in the detergent coming into contact with the impurities on the inner wall of the reactor, thereby improving the cleaning effect of the impurities on the inner wall of the reactor.

[0023] (2) This solution is achieved through the mutual cooperation of the motor, the mounting tube, the propeller, the water inlet hole, the drain hole and the filter plate. When the motor drives the mounting tube to rotate, the liquid that enters the mounting tube through the water inlet hole is subjected to the upward thrust of the propeller. Under the action of the thrust, the liquid in the mounting tube is gradually discharged through the drain hole, and the space below the propeller in the mounting tube is in a negative pressure state. At this time, the mounting tube absorbs liquid from the elastic sleeve through the water inlet hole, so the elastic sleeve is also in a negative pressure state, and absorbs liquid from the reactor through the water suction valve. During the soaking process, impurities on the inner wall of the reactor are Gradually loosen and suspend in the liquid or dissolve. When the elastic sleeve is in a negative pressure state, the elastic sleeve absorbs the liquid containing impurities between the inner wall of the reactor and the outer wall of the elastic sleeve through the water suction valve. The impurities suspended in the liquid will flow into the elastic sleeve with the liquid and contact the filter plate; at this time, the filter plate filters the liquid containing impurities, reducing the impurity content in the liquid passing through the filter plate, reducing the impurity content in the liquid discharged from the installation pipe, increasing the probability of contact between the effective substances in the liquid and the impurities on the inner wall of the reactor, improving the dissolution effect of impurities, and further improving the cleaning efficiency.

[0024] (3) This solution uses a stirring rod to stir the liquid in the groove, which significantly increases the contact area between the liquid discharged from the suction valve and the filter plate. This stirring action not only effectively reduces the filtration load of the filter plate, but also ensures the uniformity of the filtration process, thereby significantly improving the filtration efficiency. In addition, this design also effectively prevents the filter plate from clogging due to the accumulation of impurities, further ensuring the stable operation and long-term use of the system.

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Example 1:

[0035] See also Figures 1 to 7 , a stainless steel reactor high-efficiency cleaning device, comprising a mounting frame 1;

[0036] A mounting tube 2 is vertically rotatably mounted on the mounting frame 1, and two cylindrical mounting plates 3 are symmetrically fixedly mounted on the mounting tube 2. An elastic sleeve 4 is commonly sleeved on the exterior of the two mounting plates 3.

[0037] A plurality of electric telescopic rods 5 are fixedly mounted horizontally on the side wall of each mounting plate 3. The elastic sleeve 4 is sleeved on the outside of the electric telescopic rods 5. The electric telescopic rods 5 on each mounting plate 3 are evenly distributed around the center of the corresponding mounting plate 3. The electric telescopic rods 5 on two mounting plates 3 correspond to each other one by one. A push rod 6 is installed between the output ends of the two electric telescopic rods 5 on the same vertical line.

[0038] A water suction valve 7 is fixedly embedded on the top wall of the mounting plate 3 located below in the elastic sleeve 4. The input end of the water suction valve 7 passes through the elastic bottom wall and is connected to the outside world. A filter plate 8 is provided at the position between the two mounting plates 3 in the elastic sleeve 4. The filter plate 8 is made of activated carbon or ceramic membrane, and the filter plate 8 covers the surface of the output end of the water suction valve 7, and the filter plate 8 is fixedly connected to the mounting plate 3 located below. A drainage hole 9 is provided on the side wall of the mounting tube 2 at a position above the top wall of the elastic sleeve 4. A water inlet hole 10 connected to the elastic sleeve 4 is provided on the side wall of the mounting tube 2. The water inlet hole 10 is located above the filter plate 8, and the mounting tube 2 is provided with a circulation mechanism for draining water from the elastic sleeve 4 through the drainage hole 9.

[0039] Wherein, a first annular sleeve and a second annular sleeve are sleeved on the outer wall of the mounting tube 2 .

[0040] A third circular ring sleeve is rotatably sleeved on the outer wall of the first circular ring sleeve, and a fourth circular ring sleeve is rotatably sleeved on the outer wall of the second circular ring sleeve.

[0041] Then the third annular sleeve and the fourth annular sleeve are electrically connected to an external power source.

[0042] Then, the first annular sleeve and the second annular sleeve are electrically connected to the electric telescopic rod 5 , thereby supplying power to the electric telescopic rod 5 .

[0043] like Figure 3 As shown, the circulation mechanism includes a motor 11 fixedly mounted on the mounting frame 1, and the motor 11 is used to drive the mounting tube 2 to rotate;

[0044] A propeller 12 is fixedly mounted within the mounting tube 2. As the mounting tube 2 rotates, so does the propeller 12. Propeller 12 consists of multiple twisted blades, similar in shape to those found on airplanes or ships. As propeller 12 rotates within the water pipe, its blades exert a force on the water, causing it to flow in the direction of propeller 12's rotation. This operating principle is based on the blades' rotational motion transferring kinetic energy to the water, imparting speed and direction to the water.

[0045] like Figure 4 As shown, the output end of the electric telescopic rod 5 passes through the elastic sleeve 4, and the end surface of the output end of the electric telescopic rod 5 is horizontally fixedly installed with a sleeve 13, and the end of the sleeve 13 away from the electric telescopic rod 5 is horizontally slidably inserted with an insertion rod 14, and a first spring 15 is installed between the insertion rod 14 and the inner wall of the sleeve 13, and the end of the insertion rod 14 away from the sleeve 13 is installed with a scraper 16, wherein the scraper 16 is triangular prism-shaped. When the scraper 16 moves, the edge of the scraper 16 contacts the inner wall of the kettle body, and the scraper 16 pushes the impurities at a certain angle to generate shear force, and this shearing action makes it easier to roll up or peel off the impurities.

[0046] First, disassemble the kettle body and the kettle cover, and then place the mounting bracket 1 on the top surface of the kettle body.

[0047] Then the electric telescopic rod 5 is started, so that the extension amount of each electric telescopic rod 5 is the same, so that the elastic sleeve 4 can be pushed to expand by the push rod 6, so that the side wall of the elastic sleeve 4 is close to the inner wall of the kettle body, reducing the volume of the space between the reactor and the elastic sleeve 4. Therefore, when the detergent is subsequently injected, the consumption of the detergent is saved. At the same time, the volume of the space where the detergent is located is smaller, which increases the probability of the effective ingredients in the detergent coming into contact with the impurities on the inner wall of the reactor, thereby improving the cleaning effect of the impurities on the inner wall of the reactor.

[0048] Then, a cleaning agent is injected into the space between the outer wall of the elastic sleeve 4 and the inner wall of the kettle body, so that impurities attached to the inner wall are dissolved or loosened by soaking. During the soaking process, the motor 11 is started.

[0049] When the motor 11 drives the mounting tube 2 to rotate, the liquid entering the mounting tube 2 through the water inlet hole 10 is subjected to the upward thrust of the propeller 12. Under the action of the thrust, the liquid in the mounting tube 2 is gradually discharged through the drain hole 9, and the space below the propeller 12 in the mounting tube 2 is in a negative pressure state. At this time, the mounting tube 2 absorbs liquid from the elastic sleeve 4 through the water inlet hole 10. Therefore, the elastic sleeve 4 is also in a negative pressure state, and absorbs liquid from the reactor through the water suction valve 7.

[0050] During the soaking process, the impurities on the inner wall of the reactor gradually loosen and are suspended in the liquid or dissolved. When the elastic sleeve 4 is in a negative pressure state, the elastic sleeve 4 absorbs the liquid containing impurities between the inner wall of the reactor and the outer wall of the elastic sleeve 4 through the water suction valve 7. At this time, the impurities suspended in the liquid will flow into the elastic sleeve 4 with the liquid and contact the filter plate 8.

[0051] At this time, the filter plate 8 filters the liquid containing impurities, reducing the impurity content in the liquid passing through the filter plate 8, reducing the impurity content in the liquid discharged from the installation pipe 2, increasing the probability of contact between the effective substances in the liquid and the impurities on the inner wall of the reactor, improving the dissolution effect of impurities, and further improving the cleaning efficiency.

[0052] During the extension of the electric telescopic rod 5, the insertion rod 14 is in a state of being extended to the maximum from the sleeve 13 under the action of the first spring 15, so the scraper 16 gradually contacts the inner wall of the reactor or the surface of impurities, so that in the process of the mounting tube 2 driving the mounting plate 3 to rotate, the scraper 16 can be driven to scrape the surface of the impurities, thereby scraping off the loose impurities in time, increasing the probability of contact between the unloosened impurities and the cleaning agent, and further improving the work efficiency. At the same time, the rotating scraper 16 can drive the liquid cleaning agent to shake. During the shaking process, the solid impurities scraped off will flow with the liquid. In this process, the loose impurities attached to the inner wall of the reactor are impacted by the impurities suspended in the liquid, further improving the cleaning effect of the impurities on the inner wall of the reactor.

[0053] like Figure 3 As shown, a groove is provided on the bottom wall of the filter plate 8, the water suction valve 7 is connected to the groove, and stirring rods 17 are evenly installed on the side wall of the installation pipe 2 in a circumferential manner, and the stirring rods 17 are located in the groove.

[0054] As the mounting tube 2 rotates, the stirring rod 17 continuously agitates the liquid within the groove, significantly increasing the contact area between the liquid discharged from the suction valve 7 and the filter plate 8. This stirring action not only effectively reduces the filtration load on the filter plate 8 but also ensures uniform filtration, significantly improving filtration efficiency. Furthermore, this design effectively prevents clogging of the filter plate 8 due to impurity accumulation, further ensuring stable operation and long-term performance of the system.

[0055] like Figure 5 As shown, a guide cavity 18 is provided on the scraper 16, and through holes 19 communicating with the outside are evenly provided on the side walls of the guide cavity 18. A conduit 20 is fixedly installed in the drainage hole 9, and one end of the conduit 20 is communicated with the drainage hole 9, so that the liquid discharged from the drainage hole 9 can flow into the conduit 20, and the end of the conduit 20 away from the drainage hole 9 extends into the guide cavity 18.

[0056] During the drainage process, part of the liquid flows out through the drainage hole 9 and then flows orderly along the conduit 20 into the interior of the diversion cavity 18. Subsequently, the liquid is smoothly discharged through the through hole 19.

[0057] Because scraper 16 is in close contact with the inner wall of the reactor, the distance between the clean liquid discharged from through-hole 19 in scraper 16 and the inner wall of the reactor is relatively small. This allows the cleaning liquid discharged from through-hole 19 to promptly and fully contact impurities adhering to the inner wall of the reactor. This close contact greatly improves the cleaning effect of impurities on the inner wall of the reactor, thereby significantly improving the overall cleaning efficiency.

[0058] like Figure 5 As shown, a guide rod 21 is fixedly installed horizontally on the side wall of the guide cavity 18 of the through hole 19, and a striking rod 22 is movably sleeved on the guide rod 21. A second spring 23 is installed between the striking rod 22 and the side wall of the guide cavity 18.

[0059] Among them, a socket is opened on the impact rod 22, and the guide rod 21 is slidably inserted in the socket; the impact block and the guide rod 21 are made of stainless steel; when the second spring 23 is deformed to the maximum extent, the distance between the end of the impact rod 22 away from the guide rod 21 and the inner wall of the reactor is 1 mm, so the impact rod 22 will not directly hit the inner wall of the reactor.

[0060] During the dynamic process of liquid discharge through through-hole 19, the liquid flowing out of through-hole 19 directly impacts the end surface of impact rod 22. At this point, because the impact force generated by the liquid flow is greater than the elastic force of second spring 23, impact rod 22, guided by guide rod 21, moves and strikes impurities adhering to the inner wall of the reactor. This impact effectively breaks up the impurities. Once the impurities are broken up, their contact area with the cleaning agent increases, and some impurities are knocked off by the impact, significantly improving the cleaning efficiency of the reactor inner wall.

[0061] like Figure 5 As shown, the end surface of the striking rod 22 away from the guide rod 21 is a pointed end.

[0062] During the impact process, the tip can concentrate the force and exert greater pressure on the impurities, thereby effectively improving the effect of breaking up the impurities attached to the inner wall of the reactor.

[0063] like Figure 3 As shown, both ends of the mounting tube 2 are in a sealed state, and a rotating rod 24 is vertically rotatably inserted on the top wall of the mounting tube 2. The bottom end of the rotating rod 24 extends into the mounting tube 2. A blocking plate 25 is fixedly installed at the bottom end of the rotating rod 24. The blocking plate 25 is used to block the drainage hole 9, and the top end of the rotating rod 24 is fixedly connected to the mounting frame 1;

[0064] The cross section of the blocking plate 25 is semicircular, so the blocking plate 25 can only block part of the drainage hole 9 .

[0065] A driven gear 26 is fixedly mounted on the outer wall of the mounting tube 2 , and a driving gear 27 is fixedly mounted on the output end of the motor 11 . The driving gear 27 is meshed with the driven gear 26 .

[0066] When the motor 11 drives the driving gear 27 to rotate, the driven gear 26 meshing with the driving gear 27 also rotates, thereby driving the mounting pipe 2 to rotate normally; and the rotating rod 24 can normally pass through the top of the mounting pipe 2 and be fixedly connected to the mounting frame 1, which plays a role in keeping the rotating rod 24 in a stationary state. Therefore, during the rotation of the mounting pipe 2, the rotating rod 24 is in a stationary state, thereby enabling the blocking plate 25 to intermittently block each drainage hole 9.

[0067] Thereby, the impact rod 22 in the corresponding guide cavity 18 can be intermittently subjected to the impact force of the liquid, which ensures that the impact rod 22 can intermittently impact the impurities and improves the cleaning effect.

[0068] like Figure 5As shown, a slide groove is vertically opened on the side wall of the scraper 16 close to the electric telescopic rod 5, and the output end of the electric telescopic rod 5 is slidably installed in the slide groove. Therefore, under the action of gravity, the scraper 16 will automatically fall onto the inner bottom wall of the reactor, thereby improving the cleaning effect of the inner wall of the reactor.

[0069] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed by the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
