Description

Technical Field

[0001] This utility model relates to the field of reactor maintenance technology, and in particular to a reactor unblocking device with anti-splash function. Background Technology

[0002] In industries such as chemical, pharmaceutical, and food processing, reaction vessels serve as core reaction containers, and the unobstructed flow of their bottom valves directly impacts production efficiency and operational safety. During long-term use, solid materials inside the reaction vessel can easily accumulate at the bottom valve due to reaction residues, temperature changes, and other factors, leading to blockages. This not only interrupts the production process but also necessitates shutdown for unblocking. Traditional unblocking methods often rely on manual cleaning using simple tools (such as iron rods and flexible hoses). During this process, residual liquid inside the reaction vessel can easily splash out as the blockage is cleared, causing material waste and environmental pollution. Furthermore, the corrosive and high-temperature properties of the liquid can pose safety threats to operators. Therefore, reaction vessel unblocking devices with anti-splash functionality are needed.

[0003] In existing technologies, some solutions have been proposed for unclogging the bottom valve of a reactor, but these solutions still suffer from drawbacks such as limited functionality, insufficient anti-splashing effect, or low unclogging efficiency. For example, a Chinese patent (CN220940595U) proposes an anti-clogging and unclogging device for the bottom valve. This patent uses a rotating scraper and a flushing pipe at the bottom valve to scrape away deposits on the inner wall of the valve, while the flushing pipe sprays liquid to assist in cleaning. However, this patent only solves the problem of cleaning the bottom valve blockage and does not design a dedicated liquid receiving structure. During the unclogging process, the flushing liquid and the removed deposits still splash from the connection gap between the bottom valve and the device, failing to effectively avoid the safety risks and material waste caused by liquid splashing. Furthermore, the fixed positions of the scraper and flushing pipe make it difficult to adjust flexibly according to the blockage depth, resulting in limited cleaning effect on deep blockages in the bottom valve and a tendency for incomplete cleaning leading to secondary blockages.

[0004] Therefore, we propose a reactor unblocking device with anti-splash function to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a reactor unblocking device with anti-splash function, which solves the problems of incomplete anti-splash effect, insufficient unblocking flexibility and efficiency, and poor device adaptability and sealing in the existing reactor bottom valve unblocking device.

[0011] Preferably, the inside of the liquid receiving tank is equipped with a slot, the top of the slot is higher than the bottom of the inside of the liquid receiving tank, and the bottom of the slot extends through the bottom of the liquid receiving tank and has a tightening opening.

[0012] The center of the slot is hollowed out, and the cleaning rod slides into the center of the slot.

[0013] Preferably, the cleaning structure includes a first bevel gear, a rotating seat, and a second bevel gear, with the end of the cleaning rod facing away from the water pipe narrowed and fixedly mounted with the first bevel gear;

[0014] A rotating seat is rotatably mounted on one end of the cleaning rod near the first bevel gear, and a second bevel gear is rotatably mounted on one side of the rotating seat;

[0015] The first bevel gear meshes with the second bevel gear.

[0016] Preferably, a cleaning nozzle is fixedly installed on the side of the second bevel gear away from the rotating seat;

[0017] A set of nozzles is fixedly installed around the cleaning nozzle, and a nozzle is also installed in the middle of the side of the cleaning nozzle away from the second bevel gear.

[0021] The lever is L-shaped, and the other ends of the two sets of connecting rods are respectively hinged to the two sides of the corner of the L-shaped lever.

[0022] This utility model has at least the following beneficial effects:

[0023] Comprehensive anti-splash effect and stable sealing: The device achieves a close fit with the bottom valve of the reactor without structural interference by using the rim of the receiving tank with the same inner diameter as the tank body but a smaller outer diameter, forming a reliable anti-splash receiving space; at the same time, the design of the slot top being higher than the bottom of the receiving tank prevents liquid and sediment from flowing back into the gap between the cleaning rod and the slot. Combined with the fixing clip to stably fix the cleaning rod, it further maintains the close fit and sealing between the device and the bottom valve.

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0034] Reference Figure 1-5 A reactor unblocking device with anti-splash function includes a liquid receiving tank 1, a cleaning rod 2 slidably connected inside the liquid receiving tank 1, and a water pipe 3 installed at the bottom end of the cleaning rod 2. It also includes:

[0035] The inside of the liquid receiving tank 1 is equipped with a slot 7, and a fixing clip 4 is fitted onto the bottom of the slot 7;

[0036] A cleaning structure 5 is installed on one side of the top of the cleaning rod 2, and a cleaning nozzle 12 is installed on one side of the cleaning structure 5.

[0037] Furthermore, a rim 6 is fixedly installed at the opening of the receiving tank 1, and the rim 6 has the same inner diameter as the receiving tank 1, while the outer diameter of the rim 6 is smaller than that of the receiving tank 1. The consistency between the rim 6 and the inner diameter of the receiving tank 1 ensures that the liquid receiving area at the opening of the receiving tank 1 is completely matched with the internal space of the tank body, avoiding the problem of liquid leakage from the connection between the rim and the tank body due to mismatch between the inner diameter of the rim and the tank body, and further enhancing the anti-splashing effect. On the other hand, the outer diameter of the rim 6 is smaller than that of the outer edge of the receiving tank 1, so that when the receiving tank 1 is connected to the bottom valve of the reactor, the rim will not interfere with the surrounding structure of the bottom valve due to its large outer diameter, ensuring that the receiving tank 1 can be accurately and stably fitted with the bottom valve. At the same time, it is also convenient for operators to quickly position and install, improving the ease of use of the device and reducing the risk of liquid splashing caused by installation deviation.

[0038] Furthermore, a slot 7 is installed inside the liquid receiving tank 1. The top of the slot 7 is higher than the bottom of the liquid receiving tank 1, and the bottom of the slot 7 extends through the bottom of the liquid receiving tank 1 and has a tightening opening 8.

[0039] The center of slot 7 is hollowed out, and the cleaning rod 2 is slidably fitted into the center of slot 7. First, the top of slot 7 is higher than the bottom of the liquid receiving tank 1, which prevents the liquid in the receiving tank 1 from flowing back into the slot 7, preventing liquid from entering the gap between the cleaning rod 2 and slot 7, reducing component corrosion, extending the service life of the device, and also preventing the sliding flexibility of the cleaning rod 2 from being affected by liquid backflow. Second, the tightening port 8 at the bottom of slot 7 can limit and guide the cleaning rod 2 to a certain extent, ensuring that the cleaning rod 2 maintains a stable trajectory during sliding, preventing the cleaning rod 2 from shaking and causing misalignment with the bottom valve, thus preventing liquid splashing during the unblocking process. In addition, the slidable fitting of the cleaning rod 2 into the center of slot 7 allows the insertion depth of the cleaning rod 2 to be flexibly adjusted according to the blockage of the bottom valve, enabling more precise unblocking of the blocked area, improving unblocking efficiency, and the sliding connection method is convenient to operate, reducing the workload of the operator.

[0040] Furthermore, the cleaning structure 5 includes a first bevel gear 9, a rotating seat 10, and a second bevel gear 11. The end of the cleaning rod 2 facing away from the water pipe 3 is narrowed and fixedly mounted with the first bevel gear 9.

[0041] A rotating seat 10 is rotatably mounted on one end of the cleaning rod 2 near the first bevel gear 9, and a second bevel gear 11 is rotatably mounted on one side of the rotating seat 10;

[0042] The first bevel gear 9 meshes with the second bevel gear 11. When the cleaning rod 2 moves or rotates, the meshing of the first bevel gear 9 and the second bevel gear 11 drives the second bevel gear 11 and the subsequently connected cleaning components to move synchronously, achieving efficient power transmission. This transmission method has high transmission efficiency and a stable transmission ratio, ensuring precise and controllable movement of the cleaning components. Depending on the specific situation of blockage in the bottom valve, the cleaning angle and force of the cleaning components can be changed by adjusting the movement of the cleaning rod 2, thereby more comprehensively and thoroughly cleaning solid deposits inside the bottom valve and reducing the problem of re-blockage caused by incomplete cleaning. Simultaneously, the rotating seat 10 provides stable installation and rotational support for the second bevel gear 11, ensuring the stability and reliability of the gear transmission and extending the service life of the cleaning structure 5.

[0043] Furthermore, a cleaning nozzle 12 is fixedly installed on the side of the second bevel gear 11 opposite to the rotating seat 10;

[0044] A set of nozzles is fixedly installed around the cleaning nozzle 12, and a nozzle is also installed in the middle of the side of the cleaning nozzle 12 away from the second bevel gear 11.

[0045] The water pipe 3 extends through the interior of the cleaning rod 2 and towards one side of the cleaning nozzle 12, where it is movably connected. The cleaning nozzle 12 has nozzles positioned around its perimeter and in the center, enabling comprehensive flushing of the bottom valve's interior. Whether it's the inner wall of the bottom valve, the gaps around the blockage, or the central blockage area, the flushing liquid can cover everything, significantly improving the cleaning effect, effectively removing solid deposits, and preventing residual deposits from causing re-clogging of the bottom valve. The movable connection between the water pipe 3 and the cleaning nozzle 12 allows the cleaning nozzle 12 to adjust its flushing angle with the rotation of the second bevel gear 11, further expanding the flushing range. This movable connection also facilitates the disassembly and replacement of the cleaning nozzle 12. When the nozzle becomes clogged or damaged, operators can quickly perform maintenance, reducing maintenance costs and downtime. In addition, the flushing fluid is sprayed out through the cleaning nozzle 12, which can soften and assist in cleaning the blockage during the unblocking process, reduce the resistance of the cleaning rod 2 when unblocking, improve the unblocking efficiency, and the flushing process can promptly remove the cleaned sediment, preventing the sediment from accumulating in the bottom valve and causing secondary blockage. It also reduces the risk of liquid splashing caused by sediment stuck in the gap between the device and the bottom valve.

[0046] Furthermore, the fixing card 4 includes a fixing block 13, an arc plate 14, a connecting rod 15 and a lever 16. A set of arc plates 14 are respectively provided on both sides of the tightening port 8, and the same side of the two sets of arc plates 14 are hinged together with the fixing block 13.

[0047] A set of connecting rods 15 are hinged to both ends of a set of arc plates 14 on the side away from the fixed block 13, and a lever plate 16 is hinged to the side of another set of arc plates 14 on the side away from the fixed block 13.

[0048] The lever 16 is L-shaped, and the other ends of the two sets of connecting rods 15 are hinged to the two sides of the corner of the L-shaped lever 16. By turning the L-shaped lever 16, the operator can use the transmission action of the connecting rods 15 to drive the two sets of arc plates 14 to rotate around the hinge point with the fixed block 13, thereby opening and closing the two sets of arc plates 14. When it is necessary to fix the cleaning rod 2, turning the lever 16 will bring the two sets of arc plates 14 closer together and clamp the cleaning rod 2, which can stably fix the cleaning rod 2 in the required position, preventing the cleaning rod 2 from sliding or shifting due to force during the unblocking process, ensuring the stability and accuracy of the unblocking operation, and reducing the liquid splashing problem caused by the failure of the seal between the device and the bottom valve due to the movement of the cleaning rod 2. When it is necessary to adjust the position of the cleaning rod 2, turning the lever 16 in the opposite direction will release the two sets of arc plates 14. The operation is simple and quick, without the need for additional tools, which greatly improves the ease of operation of the device and reduces the difficulty and intensity of the operator's work. Meanwhile, the design of the arc plate 14 can better fit the outer circular surface of the cleaning rod 2, increase the contact area, improve the fixing effect, and prevent the cleaning rod 2 from shaking in the fixed state.

[0049] In summary:

[0050] Before using the device, the operator aligns the receiving tank 1 with the bottom valve of the reactor, using the rim 6 at the opening of the receiving tank 1 to complete the connection. The rim 6 has the same inner diameter as the receiving tank 1 and a smaller outer diameter than the outer edge of the receiving tank 1, which avoids interference with the surrounding structure of the bottom valve. At the same time, it allows the receiving tank 1 to fit against the bottom valve, forming a splash-proof receiving space. Then, the position of the cleaning rod 2 in the slot 7 inside the receiving tank 1 is adjusted so that the cleaning structure 5 and the cleaning nozzle 12 at the top of the cleaning rod 2 are aligned with the blocked area of ​​the bottom valve. After the cleaning rod 2 is adjusted to the target position, the operator moves the L-shaped lever 16 of the fixing clip 4. The lever 16 drives the arc plates 14 on both sides of the tightening port 8 to rotate around the fixing block 13 through the connecting rod 15, so that the two sets of arc plates 14 come closer to each other and clamp the cleaning rod 2, fixing it stably in the slot 7, ensuring the stability of the cleaning nozzle 12, and maintaining the tight seal between the receiving tank 1 and the bottom valve. Water is supplied through water pipe 3, and the water flows through the internal channel of cleaning rod 2 to cleaning nozzle 12. The nozzles around and in the center of cleaning nozzle 12 spray rinsing fluid. The reaction force generated by the spraying rinsing fluid causes cleaning nozzle 12 to rotate, which in turn drives the second bevel gear 11 fixed to it to rotate. Since the second bevel gear 11 meshes with the first bevel gear 9 fixed on cleaning rod 2, and the first bevel gear 9 is in a fixed position, the second bevel gear 11 will rotate around the first bevel gear 9. Rotating seat 10 provides stable support for it. During the rotation of cleaning nozzle 12, the multi-directional nozzles continuously spray rinsing fluid, covering the inner wall of the bottom valve, the gaps around the blockage, and the central area, softening the solid deposits. At the same time, the rotational motion expands the rinsing range, peeling the softened deposits from the inner wall of the bottom valve. The peeled deposits flow into the receiving tank 1 with the rinsing fluid. The top of slot 7 is higher than the bottom of the receiving tank 1, which prevents liquid from flowing back into the gap between slot 7 and cleaning rod 2, thus preventing deposits from getting stuck. If the bottom valve is still blocked deep inside, the operator reverses the lever 16 to loosen the cleaning rod 2. The operator then pushes or pulls the cleaning rod 2 within the slot 7 to adjust the insertion depth of the cleaning nozzle 12. The tightening port 8 acts as a guide. After adjustment, the cleaning rod 2 is re-secured, and cleaning continues until the bottom valve is clear. Throughout the process, the receiving tank 1 collects the flushing fluid and sediment, preventing liquid splashing and secondary blockage. After clearing, the water pipe 3 is shut off, the fixing clip 4 is released, and the cleaning rod 2 is removed. If the cleaning nozzle 12 requires maintenance, it can be disassembled and replaced using its movable connection to the water pipe 3. Sediments in the receiving tank 1 can be directly poured out for cleaning. There is no backflow of liquid through the gap between the slot 7 and the cleaning rod 2, reducing component corrosion.
