Abstract
Description
Technical Field
[0001] This utility model relates to the field of reaction vessel technology, and specifically to a reaction vessel cleaning device. Background Technology
[0002] Reactors, characterized by high temperature resistance, corrosion resistance, wear resistance, and high production capacity, are containers used for physical or chemical reactions. They are widely used in industries such as pharmaceuticals, dyes, petroleum, chemicals, and food to perform processes such as evaporation, heating, and cooling. They are reaction equipment used to complete processes such as sulfidation, nitration, hydrogenation, hydrocarbonation, polymerization, and condensation. After a period of use, scale will form on the reactor, reducing its heat exchange performance, increasing reaction time, and accelerating corrosion. Therefore, it is necessary to clean the reactor regularly.
[0003] To facilitate cleaning, some existing technologies, such as the patent with publication number CN 212597711U, use a rack-type cleaning device installed inside the reactor. This cleaning device includes a mounting frame installed in the middle of the reactor, with cleaning plates arranged around the frame. The mounting frame drives the cleaning plates to move up and down, thus cleaning the inner wall of the reactor. This method has the following drawbacks:
[0004] 1. Existing reactors generally consist of a reactor body, a reactor cover, and a stirring device connected to the reactor cover and inserted into the reactor body. Therefore, if the existing frame-type cleaning device is installed inside the reactor body, it will inevitably cause interference with the stirring device.
[0005] 2. Since the inner wall of the reactor is generally not smooth, a rigid frame-type cleaning device is used. During the rotation of the mounting frame, the cleaning plate is not able to slide smoothly on the inner wall of the reactor, resulting in a rigid cleaning effect. Utility Model Content
[0006] In view of the shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide a reaction vessel cleaning device that can conveniently and quickly clean the entire inner cavity of the reaction vessel, thereby improving the cleaning effect.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a reaction vessel cleaning device, comprising:
[0008] A high-pressure pipe, the inlet end of which can be connected to a high-pressure flushing liquid source;
[0009] A high-pressure nozzle, located at the discharge end of the high-pressure pipe, has multiple jet holes arranged in a spatial array to form a multidirectional jet flow field;
[0010] The lifting mechanism is axially extendable. The high-pressure nozzle is installed at the end of the lifting mechanism. The lifting mechanism can drive the high-pressure nozzle to be inserted into the reactor body through the process hole of the reactor cover and perform axial displacement. The high-pressure pipe passes through the internal channel of the lifting mechanism.
[0011] Furthermore, the lifting mechanism includes a lifting rod and a snap-fit lifting drive source. The lifting rod includes two opposing clamping bars that can be snapped together to form a vertical, rigid lifting rod. The high-pressure nozzle is installed at the bottom end of the lifting rod, and the high-pressure pipe is clamped between the two clamping bars.
[0012] The locking and lifting drive source is located on the upper cover of the reactor and is drivably connected to the two clamping bars. It has a first working state in which the two clamping bars move relative to each other to achieve engagement and locking, and a second working state in which the clamping bars separate in the opposite direction.
[0013] Furthermore, each of the clamping bars includes multiple chain-link clamping plate units, and adjacent clamping plate units are connected by a hinge shaft to form a flexible chain belt; the chain-link clamping plate unit is provided with mutually cooperating engagement protrusions and engagement grooves, and each engagement protrusion has a notch on its sidewall, and the notch sequentially forms the internal channel, through which the high-pressure pipe passes.
[0014] Furthermore, the snap-fit lifting drive source includes a housing, a mounting plate, a bidirectional rotational power source, and two actuating wheels; the housing can be installed on the top of the reactor cover, and the housing is provided with two guide grooves that are symmetrically arranged on the left and right sides. The bottom ends of the two guide grooves are connected to each other, and the tops of the two guide grooves gradually spread outward from each other. The two clamping strips are slidably arranged in the two guide grooves respectively.
[0015] There are two actuating wheels, which are rotatably mounted opposite each other on the housing. The bottom ends of the two clamping bars can slide through the gap between the two actuating wheels. The bidirectional rotational power source is connected to the two actuating wheels and is used to drive the two actuating wheels to rotate relative to each other or in opposite directions. During the relative rotation of the two actuating wheels, the two clamping plates can be pulled downward and locked together. During the in opposite rotation of the two actuating wheels, the two clamping plates can be pulled upward and locked together.
[0016] The high-pressure nozzle is installed at the end of the lifting rod that extends from the bottom of the housing.
[0017] Furthermore, it also includes a storage unit, of which there are two, each used to automatically store the two clips, and which can automatically release the line when subjected to an outward pulling force.
[0018] Furthermore, the storage device includes a winding shaft and a spiral blade. Both ends of the winding shaft are rotatably connected to the housing through the spiral blade, and the tail end of the clamping bar is wound around the winding shaft.
[0019] The beneficial effects of this utility model are:
[0020] In use, the aforementioned reactor cleaning device connects a high-pressure pipe to a high-pressure flushing liquid source via a flange interface. A lifting mechanism carries a high-pressure nozzle, which is vertically inserted into the reactor through a process port on the reactor lid. As the lifting mechanism moves the high-pressure nozzle up and down, it creates a multi-directional jet flow field that covers the inner wall of the reactor for cleaning.
[0021] This reactor cleaning device features an internal channel design on the lifting rod that prevents the high-pressure pipe from being exposed and arbitrarily positioned. The spherical jet hole layout enables thorough cleaning without dead angles, improving cleaning efficiency. The telescopic lifting rod is adaptable to reactors of different heights, enhancing versatility. Furthermore, this method allows for the efficient cleaning of the reactor body and the inner wall of the reactor cover, as well as the stirring device, thereby improving the overall cleaning effect of the reactor.

[0030] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the invention; therefore, the invention is not limited to the specific embodiments disclosed below.
[0031] Please see Figures 1 to 3 This utility model provides a reactor cleaning device, including a high-pressure pipe 100, a high-pressure nozzle 200 and a lifting mechanism 300.
[0032] Specifically, the inlet end of the high-pressure pipe 100 can be connected to a high-pressure flushing liquid source, and the high-pressure nozzle 200 is located at the outlet end of the high-pressure pipe 100. The high-pressure nozzle 200 has multiple jet holes arranged in a spatial array to form a multidirectional jet flow field. The high-pressure nozzle 200 can adopt a spherical structure with multiple conical jet holes evenly opened on its surface. In specific implementation, the cleaning liquid is first placed into the high-pressure flushing liquid source, and the cleaning liquid can be gasoline or other commonly used reactor cleaning liquid.
[0033] The lifting mechanism 300 can extend and retract axially. The high-pressure nozzle 200 is installed at the end of the lifting mechanism 300. The lifting mechanism 300 can drive the high-pressure nozzle 200 to be inserted into the reactor body through the process hole of the reactor cover and perform axial displacement. The high-pressure pipe 100 passes through the internal channel of the lifting mechanism 300.
[0034] In use, the high-pressure pipe 100 is connected to the high-pressure flushing liquid source through a flange interface; the lifting mechanism 300 carries the high-pressure nozzle 200 and is vertically inserted into the reactor through the process hole on the reactor lid. During the process of the lifting mechanism 300 driving the high-pressure nozzle 200 to move up and down, the high-pressure nozzle 200 forms a multi-directional jet flow field to cover the inner wall of the reactor for cleaning.
[0035] This reactor cleaning device features an internal channel design on the lifting rod that prevents the high-pressure pipe from being exposed and thus avoids arbitrary movement. The spherical jet hole layout enables thorough cleaning without dead angles, improving cleaning efficiency. The telescopic lifting rod is adaptable to reactors of different heights, enhancing versatility. Furthermore, this method allows for the efficient cleaning of the reactor body and the inner wall of the reactor cover, as well as the simultaneous cleaning of the reactor's stirring device, thereby improving the overall cleaning effect of the reactor.
[0036] In this embodiment, the lifting mechanism 300 includes a lifting rod 310 and a snap-fit lifting drive source 320. The lifting rod 310 includes two oppositely arranged clamping strips 311. The two clamping strips 311 can be snapped together to form a vertical, rigid lifting rod 310. The high-pressure nozzle 200 is installed at the bottom end of the lifting rod 310, and the high-pressure pipe 100 is clamped between the two clamping strips 311.
[0037] The locking and lifting drive source 320 is installed on the upper cover of the reactor and is drivably connected to the two clamping bars 311. It has a first working state in which the two clamping bars 311 are relatively translated to achieve engagement and locking, and a second working state in which the clamping bars 311 are separated in the opposite direction.
[0038] The use of this snap-fit lifting rod 310 can achieve both lifting guidance and reduce the size of the cleaning device, thereby greatly improving ease of use.
[0039] Specifically, each clamping bar 311 includes multiple link-type clamping plate units, and adjacent clamping plate units are connected by hinge shafts to form a flexible chain. The link-type clamping plate units are provided with mutually cooperating engagement protrusions and engagement grooves. Each engagement protrusion has a notch 312 on its side wall, and the notches 312 sequentially form internal channels, through which the high-pressure pipe 100 passes.
[0040] During operation: When the clamping bar 311 is lowered, the chain link units automatically align under gravity; the meshing protrusions and grooves form a mechanical interlock during the fastening process; the high-pressure pipe 100 passes through the continuous channel formed by the notches 312. This chain link design allows the guide rod to be bent and stored while ensuring rigidity in the working state; the trapezoidal tooth meshing structure increases the load-bearing capacity by 50% and prevents accidental disengagement; the internal channel provides protection for the high-pressure pipe.
[0041] In this embodiment, the snap-fit lifting drive source 320 includes a housing 321, a mounting plate 322, a bidirectional rotating power source 323, and two actuating wheels 324. The housing 321 can be installed on the top of the reactor cover. The housing 321 is provided with two guide grooves that are symmetrical from left to right. The bottom ends of the two guide grooves are connected to each other, and the tops of the two guide grooves gradually spread outwards from each other. Two clamping strips 311 are slidably arranged in the two guide grooves respectively.
[0042] There are two actuating wheels 324, which are rotatably mounted opposite each other on the housing 321. The bottom ends of two clamping strips 311 can slide through the gap between the two actuating wheels 324. A bidirectional rotational power source 323 is connected to the two actuating wheels 324 to drive them to rotate relative to each other or in opposite directions. During relative rotation, the two clamping plates are pulled downward and simultaneously engaged. During in opposite rotation, the two clamping plates are pulled upward and simultaneously separated. A high-pressure nozzle 200 is mounted on the end of a lifting rod 310 extending from the bottom of the housing 321.
[0043] In practical implementation, the bidirectional rotary power source 323 can preferably be a commonly used servo motor.
[0044] The work process is as follows:
[0045] Descent engagement stage: The servo motor drives the two gears to rotate in the same direction, and the clamping bar 311 slides down the guide groove and gradually engages;
[0046] The rising separation stage: the servo motor reverses, the gear rotates in the opposite direction to drive the clamp 311 to move upward and separate, and the chain link unit automatically folds and stores.
[0047] In a preferred embodiment, the device also includes a receiver 400. There are two receivers 400, which are used to automatically receive the two clips 311. When subjected to an outward pulling force, the receivers 400 can automatically release the wire.
[0048] Specifically, the storage container 400 includes a winding shaft 410 and a spiral blade 420. Both ends of the winding shaft 410 are rotatably connected to the housing 321 through the spiral blade 420, and the tail end of the clamping strip 311 is wound around the winding shaft 410.
[0049] In use, when the clamping strip 311 separates, the spiral blade 420 releases its pre-tightening force, and the winding shaft 410 automatically rotates to collect the clamping strip 311; when the clamping strip 311 unfolds, the external pulling force overcomes the pre-tightening force of the spiral blade 420, and the winding shaft 410 simultaneously releases the yarn. This method ensures that the clamping strip 311 is neatly stored and arranged.
[0050] In a preferred embodiment, the device further includes a flushing fluid recovery tank for temporarily storing the cleaning fluid recovered from the reactor. In use, if gasoline is used as the cleaning fluid, the recovered gasoline can be placed in the flushing fluid recovery tank, and after natural settling, the upper layer of gasoline can be used to clean the reactor or other areas.
[0051] How to use the above-mentioned reactor cleaning device:
[0052] When in use, first install the box on the top of the reactor lid and align the high-pressure nozzle with the process hole. Then, start the bidirectional rotary power source to drive the clamping bar to form a lifting rod and extend it vertically downward into the reactor. Then, start the high-pressure flushing liquid source. During the up-and-down movement of the lifting rod, the entire inner wall of the reactor is cleaned.
[0053] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
