Description

Technical Field

[0001] This utility model belongs to the field of reaction vessel technology, and in particular relates to a reaction vessel with self-cleaning function. Background Technology

[0002] In industrial production such as chemical, pharmaceutical, and food processing, the reactor is the core equipment for material mixing and reaction. Its stirring efficiency and the cleanliness of its inner wall directly affect product quality and production continuity. However, existing reactors still have some problems.

[0003] Traditional reactors typically require separate stirring and cleaning devices: the stirring device is usually composed of a motor-driven stirring paddle, which achieves uniform mixing of materials through mechanical stirring; while the cleaning device is usually an additional spray structure or manual cleaning tool, used to remove residual materials from the inner wall after the reaction, so as to avoid contamination of subsequent reactions by residual materials.

[0004] This separate design requires independent stirring and cleaning devices to occupy separate internal space in the reactor, which may lead to complex structure and increased equipment size. In particular, it can easily cause stirring dead zones or cleaning blind spots in small reactors. Furthermore, the driving and control of the two devices need to be carried out independently, which increases the equipment manufacturing cost. Utility Model Content

[0005] The purpose of this invention is to provide a reaction vessel with a self-cleaning function. Specifically, a cleaning component is provided by activating a bidirectional motor to rotate clockwise, which in turn rotates the shaft. Under centrifugal force, the slider is positioned above the lead screw, and the movable block moves upward. The connecting rod causes the two cleaning blocks to contract, thus the connecting rod and the cleaning blocks act as a stirrer. When cleaning is required, the bidirectional motor is activated to rotate counterclockwise. Under centrifugal force, the slider and movable block move downward, and the connecting rod causes the two cleaning blocks to expand outward, adhering to the inner wall of the reaction vessel for cleaning. This achieves both stirring and cleaning functions, solving the problem of existing reaction vessels having separate stirring and cleaning devices, which occupy space and increase costs.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a reaction vessel with a self-cleaning function, comprising a reaction vessel and a cleaning component. The cleaning component is installed inside the reaction vessel and is used for cleaning the inner wall of the reaction vessel. The cleaning component includes:

[0008] A shaft is rotatably connected inside the reactor. A bidirectional motor is fixedly connected to the top of the reactor via a mechanical seal seat. The bottom output end of the bidirectional motor is fixedly connected to the top of the shaft via a coupling.

[0009] A lead screw, which is fixedly connected above the top of a shaft, and a slider is threaded onto the outer surface of the lead screw;

[0010] The movable block is rotatably connected to the outer surface of the slider. A fixed block one is fixedly connected to the middle of the outer surface of the shaft, and a fixed block two is fixedly connected to the bottom of the outer surface of the shaft. The outer surfaces of the movable block, fixed block one, and fixed block two are all rotatably connected to two connecting rods by pins.

[0011] Two cleaning blocks are disposed inside the reactor. Two connecting blocks are fixedly connected to the side of each cleaning block near the shaft. The corresponding sides of the two connecting blocks are rotatably connected to the side of the connecting rod away from the shaft via pins.

[0012] The reactor is fixedly connected to the top of the reactor, to the bottom right side of the reactor, to the bottom of the reactor, and to the bottom of the reactor, to the reactor. Each of the reactors is equipped with a solenoid valve.

[0013] Furthermore, the cleaning block is made of silicone, and several grooves are formed on the side of the cleaning block near the inner wall of the reactor.

[0014] Furthermore, elastic protective sleeves are fitted between the movable block and the fixed block, and between the movable block and the inner wall of the top of the reactor.

[0015] Furthermore, the cleaning component also includes:

[0016] An annular spray pipe is fixedly connected to the top of the reactor, and a water inlet is provided at the top of the annular spray pipe.

[0017] Furthermore, several nozzles are fixedly connected to the bottom of the annular spray pipe, and the bottom of the nozzles penetrates the top of the reactor and extends into the interior.

[0018] Furthermore, the spray directions of the nozzles are staggered, pointing towards the inner wall of the reactor and the shaft.

[0019] This utility model has the following beneficial effects:

[0020] 1. This utility model, by setting up a cleaning component, specifically involves starting a bidirectional motor to rotate clockwise, which drives the shaft to rotate. At this time, under the action of centrifugal force, the slider is located above the lead screw, and the movable block moves upward accordingly. The connecting rod drives the two cleaning blocks to contract. At this time, the connecting rod and the cleaning blocks play a stirring and mixing role. When cleaning is required, the bidirectional motor is started to rotate counterclockwise. Under the action of centrifugal force, the slider and movable block move downward accordingly, and the connecting rod drives the two cleaning blocks to expand outward, adhering to the inner wall of the reaction vessel to scrub it. This achieves the dual functions of stirring and cleaning, improving the convenience of operation and work efficiency.

[0021] 2. This utility model features a spray pipe, specifically a water inlet through which cleaning liquid is introduced. After entering the annular spray pipe, the cleaning liquid is sprayed out through several nozzles at its bottom. The spray direction of the nozzles is staggered towards the inner wall of the reactor and the shaft, achieving all-round rinsing of the reactor interior. This can pre-wet or wash away stubborn stains. Combined with the cleaning block, it achieves a dual cleaning mode of rinsing and scraping, improving the cleaning effect.

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 scope of protection of the present utility model.

[0031] Please see Figures 1-4 As shown, this utility model has the following two specific embodiments.

[0032] Example 1

[0033] This utility model relates to a reaction vessel with a self-cleaning function, comprising a reaction vessel 1 and a cleaning component 2. The cleaning component 2 is installed inside the reaction vessel 1 and is used for cleaning the inner wall of the reaction vessel 1. The cleaning component 2 includes:

[0034] Shaft 21 is rotatably connected inside reactor 1. A bidirectional motor 211 is fixedly connected to the top of reactor 1 via a mechanical seal seat. The bottom output end of bidirectional motor 211 is fixedly connected to the top of shaft 21 via a coupling.

[0035] A lead screw 212 is fixedly connected to the top of the shaft 21, and a slider 213 is threaded onto the outer surface of the lead screw 212.

[0036] Movable block 22 is rotatably connected to the outer surface of slider 213. Fixed block 221 is fixedly connected to the middle of the outer surface of shaft 21, and fixed block 222 is fixedly connected to the bottom of the outer surface of shaft 21. Two connecting rods 223 are rotatably connected to the outer surfaces of movable block 22, fixed block 221 and fixed block 222 through pins.

[0037] Two cleaning blocks 23 are installed inside the reactor 1. Two connecting blocks 231 are fixedly connected to the side of the cleaning block 23 near the shaft 21. The corresponding sides of the two connecting blocks 231 are rotatably connected to the side of the connecting rod 223 away from the shaft 21 by a pin.

[0038] like Figures 1-3 As shown, by setting up the cleaning component 2, specifically by starting the bidirectional motor 211 to rotate clockwise, driving the shaft 21 to rotate, at which point, under the action of centrifugal force, the slider 213 is located above the lead screw 212, and the movable block 22 moves upward accordingly. The connecting rod 223 drives the two cleaning blocks 23 to contract. At this time, the connecting rod 223 and the cleaning blocks 23 play a stirring and mixing role. When cleaning is required, the bidirectional motor 211 is started to rotate counterclockwise. Under the action of centrifugal force, the slider 213 and the movable block 22 move downward accordingly, and the connecting rod 223 drives the two cleaning blocks 23 to expand, adhering to the inner wall of the reactor 1 to scrub it. This achieves the dual functions of stirring and cleaning, improving the convenience of operation and work efficiency.

[0039] The reactor 1 is fixedly connected to the top of the feed inlet 11, the reactor 1 is fixedly connected to the bottom right side of the reactor 1 to the discharge outlet 12, and the reactor 1 is fixedly connected to the bottom of the discharge outlet 13. Solenoid valves 14 are installed inside the feed inlet 11, the discharge outlet 12 and the discharge outlet 13.

[0040] The cleaning block 23 is made of silicone, and several grooves are formed on the side of the cleaning block 23 near the inner wall of the reactor 1.

[0041] An elastic protective sleeve 214 is fitted between the movable block 22 and the fixed block 221, and between the movable block 22 and the inner wall of the top of the reactor 1.

[0042] The solenoid valve 14 enables automatic material loading and unloading and centralized discharge of wastewater after cleaning, improving the automation level and production efficiency of the entire reaction process. The cleaning block 23 is made of silicone and has grooves, which reduces the risk of scratching the inner wall of the reactor. The grooves can better scrape off dirt and improve self-cleaning ability. The elastic protective sleeve 214 can effectively prevent dirt from entering the screw gap, avoid causing the mechanism to jam, and ensure the long-term reliability of the cleaning component 2.

[0043] Example 2

[0044] The difference from Embodiment 1 is that this embodiment discloses a spray pipe 24:

[0045] Cleaning component 2 also includes:

[0046] An annular spray pipe 24 is fixedly connected to the top of the reactor 1, and a water inlet 241 is provided at the top of the annular spray pipe 24.

[0047] Several nozzles 242 are fixedly connected to the bottom of the annular spray pipe 24. The bottom of the nozzles 242 penetrates the top of the reactor 1 and extends into the interior.

[0048] Several nozzles 242 spray water in an alternating manner toward the inner wall of the reactor 1 and the shaft 21.

[0049] like Figure 4 As shown, by setting up a spray pipe 24, specifically by introducing cleaning fluid through a water inlet 241, the cleaning fluid enters the annular spray pipe 24 and is sprayed out through several nozzles 242 at its bottom. The spray direction of the nozzles 242 is staggered towards the inner wall of the reactor 1 and the shaft 21, achieving all-round rinsing of the inside of the reactor 1. This can pre-wet or wash away stubborn stains. Combined with the cleaning block 23, it achieves a dual cleaning mode of rinsing and scraping, improving the cleaning effect.

[0050] A specific application of this embodiment is as follows: Material is added into the reactor 1 through the feed inlet 11. Then, the bidirectional motor 211 is started and rotated clockwise. This rotates the shaft 21 clockwise via the coupling. Under centrifugal force, the slider 213 on the outer surface of the lead screw 212 is positioned above the lead screw 212. The movable block 22, rotatably connected to the outer surface of the slider 213, moves upwards. Under the linkage of the upward movement of the movable block 22, the connecting rod 223 causes the two cleaning blocks 23 to retract, preventing them from contacting the inner wall of the reactor 1. At this time, the connecting rod 223 and the cleaning blocks 23, rotating with the shaft 21, stir and mix the material inside the reactor 1. After mixing, the material is discharged through the discharge outlet 12. When cleaning the inner wall of the reactor 1 is required, cleaning liquid is first introduced through the water inlet 241. After entering the annular spray pipe 24, the cleaning liquid passes through several nozzles 242 at its bottom. The nozzles 242 spray water in an alternating direction towards the inner wall of the reactor 1 and the shaft 21, achieving all-round rinsing of the reactor 1. This pre-wets or washes away stubborn stains. Simultaneously, the bidirectional motor 211 is started and rotates counterclockwise. Under centrifugal force, the slider 213 slides down along the lead screw 212, and the movable block 22 moves down accordingly. Through the connecting rod 223, the two cleaning blocks 23 expand outward until they adhere to the inner wall of the reactor 1. The cleaning blocks 23, rotating with the shaft 21, scrub the inner wall. The silicone material prevents scratching the inner wall of the reactor 1. The grooves enhance the cleaning effect, and the elastic protective sleeve 214 prevents dirt from entering the gap of the lead screw 212 and causing jamming. After cleaning, the wastewater is discharged through the drain port 13. During operation, the solenoid valve 14 can realize automated control of material feeding, discharging, and wastewater discharge, reducing manual operation steps.
