Description

Technical Field

[0001] This utility model belongs to the field of chemical cleaning equipment technology, specifically relating to a cleaning device for a chlorinated polyethylene reactor. Background Technology

[0002] In chemical production processes, equipment cleaning is a crucial step, especially for equipment such as reaction vessels. After the previous reaction is completed, a layer of chlorinated polyethylene residue adheres to the inner wall of the reaction vessel. In addition, after a period of use, a layer of dirt accumulates on the inner wall of the chlorination vessel. These residues and dirt can significantly affect the performance of the reaction vessel and the quality of the products. Specifically, this manifests in the following ways: (1) Attached dirt will reduce the heat exchange performance of the reactor and increase energy consumption; (2) Chlorinated polyethylene spot problem is a very important indicator of product quality, and the falling off of dirt attached to the inner wall of the reactor and the mixing of foreign matter such as residue from the previous reactor will cause the product to be overchlorinated, which is an important root cause of spot formation; (3) If dirt is attached to the temperature detector inserted into the reactor, it will cause a time delay in temperature measurement, thereby affecting the entire reaction control system; (4) If dirt is attached to the mechanical seal inside the reactor, it may cause liquid leakage inside the reactor, and there may even be a risk of gas being ejected from the reactor; (5) If dirt is attached to the bearings and rotating parts inside the reactor, it will cause excessive vibration of the agitator, damage to the mechanical shaft seal, etc., which will affect the overall safety of the production equipment.

[0003] Therefore, reaction vessels must be cleaned after a period of use. Currently, there are several common methods for removing residues from the inner walls of reaction vessels: manual cleaning, chemical cleaning, and high-pressure water jet cleaning. Manual cleaning: Its biggest advantage is its low cost. However, it requires several hours of ventilation before entering the vessel, and the oxygen concentration inside must be monitored constantly during the cleaning process, posing a risk of oxygen deficiency. Furthermore, manual scraping not only cannot completely clean the vessel but also causes scratches on the inner wall, which objectively leads to further adhesion of residues. Manual cleaning also causes hygiene problems for the product. Chemical cleaning: Its advantages are uniform and thorough cleaning. The disadvantages are a long cleaning cycle and very difficult wastewater treatment. Current environmental regulations are very strict, which may result in substantial wastewater treatment costs. High-pressure water jet cleaning: The principle is to compress water to high pressure and then release it through nozzles installed on a cleaning robot that extends into the vessel. Pressure energy is converted into the kinetic energy of the water flow, which is used to impact the dirt on the wall surface to achieve the cleaning and removal effect. Unlike the previous two cleaning methods, high-pressure water jet cleaning is a purely physical cleaning method. Due to the complex internal structure of the reactor, there are dead corners that are difficult to clean, resulting in incomplete cleaning. The residual material residues react repeatedly, increasing the difficulty of cleaning.

[0004] Therefore, a cleaning device for the reactor used in the production of chlorinated polyethylene is proposed to address the current shortcomings. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a cleaning device for chlorinated polyethylene reactors that can achieve thorough cleaning inside the reactor without dead corners, thereby improving the cleaning effect and efficiency.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is: a cleaning device for a chlorinated polyethylene reactor, including a support frame that can be supported at the reactor mouth and a rinsing mechanism installed below the support frame;

[0007] The rinsing mechanism includes a telescopic actuator installed below the support frame. A housing is installed at the telescopic end of the telescopic actuator. A water pump is installed inside the housing. A rinsing head is installed on the outside of the housing. The rinsing head is connected to the water pump through a pipeline. A cleaning brush is installed on the rinsing head. The cleaning brush is connected to the cleaning drive mechanism.

[0008] As a preferred technical solution, the support frame includes a support beam and support legs disposed at both ends of the support beam. The support legs are equipped with rollers that cooperate with the vessel opening and limiting plates located outside the rollers.

[0009] As a preferred technical solution, the support beam includes an outer beam and an inner beam that is slidably disposed within the outer beam, and the outer beam is provided with a locking pin that abuts against the inner beam.

[0010] As a preferred technical solution, handles are provided at the outer ends of the outer beam and the inner beam, respectively.

[0011] As a preferred technical solution, a lead screw is provided between the two end support legs.

The other end of the lead screw is slidably engaged with the other support leg. A moving block is threaded onto the lead screw, and the telescopic actuator is installed on the moving block.

[0012] As a preferred technical solution, a guide rod parallel to the lead screw is also provided between the two end support legs. One end of the guide rod is connected to the support leg near the lead screw drive mechanism, and the other end of the guide rod is slidably engaged with another support leg. The guide rod is also slidably engaged with the moving block.

[0013] As a preferred technical solution, the flushing head includes a flushing disc and a nozzle arranged circumferentially along the flushing disc.

[0014] As a preferred technical solution, a camera is also installed on the rear side of the rinsing head.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects:

[0016] (1) By using the nozzles that are tilted around the rinsing plate, the rinsing area can be increased and the rinsing efficiency can be improved. At the same time, in a single unidirectional moving rinsing, the area to be rinsed can be rinsed multiple times to ensure the rinsing effect. Furthermore, by setting a cleaning brush, the dirt that has not been rinsed off can be deeply cleaned.

[0017] (2) By using the screw and telescopic actuator together, the flushing head and cleaning brush can be adjusted to different positions inside the reactor to ensure the cleaning effect inside the reactor.

[0018] (3) By setting up a camera, the cleaning effect inside the reactor can be observed, and the reactor can be thoroughly cleaned to avoid the existence of cleaning dead corners.

[0019] (4) The cleaning device has a simple structure and can meet the cleaning needs of different types of reactors. At the same time, it can achieve thorough cleaning of the inside of the reactor, which greatly improves the cleaning effect. It not only avoids the problem of product quality decline due to incomplete cleaning, but also avoids the safety risks caused by operators entering the inside of the reactor to inspect it.

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0028] like Figures 1 to 5 As shown, the chlorinated polyethylene reactor cleaning device includes a support frame 100 that can be supported at the reactor opening and a rinsing mechanism 200 installed below the support frame 100.

[0029] In this embodiment, the support frame 100 includes a support beam 110 and support legs 120 disposed at both ends of the support beam 110. The support beam 110 includes an outer beam body 111 and an inner beam body 112 slidably disposed within the outer beam body 111. A locking pin 113 is provided on the outer beam body 111 to abut against the inner beam body 112. In practical applications, the length of the support beam 110 can be adjusted by adjusting the relative position between the outer beam body 111 and the inner beam body 112, thereby allowing the support beam 110 to be placed on reactors of different diameters to support the rinsing mechanism 200 disposed within the reactor.

[0030] refer to Figure 4 The support leg 120 is equipped with a roller 130 that mates with the vessel opening and a limiting plate 140 located outside the roller 130, with a certain distance between the limiting plate 140 and the roller 130. In use, the roller 130 mates with the opening of the reactor. Simultaneously, the interaction between the roller 130 and the reactor allows the support beam 110 to rotate on the reactor. The limiting plate 140 prevents misalignment between the roller 130 and the reactor, ensuring the stability of the support beam 110's rotation on the reactor.

[0031] The outer beam 111 and the inner beam 112 are respectively provided with handles 114 at their outer ends. The support beam 110 can be rotated by the handles 114 at both ends, and the cleaning device can be installed and disassembled on the reactor.

[0032] refer to Figure 1 and Figure 2 The rinsing mechanism 200 includes a telescopic actuator 201 installed below the support frame 100. The height of the rinsing mechanism 200 inside the reactor can be adjusted by telescopically extending and retracting the telescopic actuator 201. The telescopic actuator 201 is preferably an electric push rod. A container 202 is installed at the telescopic end of the telescopic actuator 201. A water pump 203 is installed inside the container 202. A rinsing head is installed on the outside of the container 202. In use, the water pump 203 is connected to an external water source. The operation of the water pump 203 supplies water to the rinsing head to achieve rinsing of the inside of the reactor.

[0033] Specifically, the rinsing head includes a rinsing disc 204 and several nozzles 205. The axis of the rinsing disc 204 is perpendicular to the axis of the telescopic actuator 201. The nozzles 205 are inclined around the rinsing disc 204 and are connected to a water pump 203 via pipelines. During cleaning, the circumferentially inclined nozzles 205 generate a large area of ​​rinsing water flow when rinsing the reactor, improving rinsing efficiency. Furthermore, in a single unidirectional rinsing motion, multiple rinsings of the area to be rinsed can be achieved, ensuring effective rinsing.

[0034] A cleaning brush 206 is mounted on the rinsing tray 204. The cleaning brush 206 is connected to a cleaning drive mechanism 207. The cleaning brush 206 is preferably a ball-head brush, and the cleaning drive mechanism 207 is preferably a servo motor, with the motor output shaft coaxial with the rinsing tray 204. During rinsing, stubborn dirt can be cleaned by the cleaning brush 206, ensuring a good cleaning effect.

[0035] See again Figure 1In this embodiment, a lead screw 150 is provided between the two end support legs 120. One end of the lead screw 150 is connected to a lead screw drive mechanism 160, which drives the lead screw 150 to rotate. The lead screw drive mechanism 160 is preferably a motor. The lead screw drive mechanism 160 is mounted on one end support leg 120, and the other end of the lead screw 150 is slidably engaged with the other support leg 120 to ensure the adjustment operation of the support beam 110. A moving block 170 is threadedly connected to the lead screw 150, and the telescopic actuator 201 is mounted on the moving block 170. Thus, by rotating the lead screw 150, the moving block 170 can be moved along the axis of the lead screw 150, thereby realizing the adjustment of the position of the flushing head and cleaning brush 206 inside the reactor, so as to facilitate the flushing of different positions inside the reactor.

[0036] See again Figure 1 A guide rod 180 parallel to the lead screw 150 is also provided between the two end support legs. One end of the guide rod 180 is connected to the support leg 120 near the lead screw drive mechanism 160, and the other end of the guide rod 180 is slidably engaged with another support leg 120. The guide rod 180 is slidably engaged with the moving block 170. In this way, the cooperation between the guide rod 180 and the lead screw 150 can ensure that the moving block 170 moves only along the axis of the lead screw 150.

[0037] In this embodiment, a camera 208 is also installed on the rear side of the rinsing head. The camera 208 is connected to the container 202 through a connecting rod. The camera 208 can be used to observe the cleaning effect inside the reactor, so that the parts that are not thoroughly cleaned can be cleaned again to ensure the cleaning effect of the reactor.

[0038] In practical implementation, a controller with wireless communication function can be built into the container 202. The lead screw drive mechanism, water pump, cleaning drive mechanism, telescopic drive and camera are all electrically connected to the controller. At the same time, the controller is connected to a handheld terminal through wireless communication function, so as to realize the operation of the device through the terminal, thereby completing the cleaning operation inside the reactor.

[0039] The above description is merely an illustrative embodiment of this utility model and is not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model.
