Description

Technical Field

[0001] This invention relates to the field of reactor cleaning technology, and more particularly to a handheld reactor cleaning device. Background Technology

[0002] In a broad sense, a reaction vessel is a container that undergoes physical or chemical reactions. Through structural design and parameter configuration, it achieves the heating, evaporation, cooling, and low-to-high-speed mixing functions required by the process. After use, materials adhere to the inner wall of the reaction vessel, and the accumulation of scale in the reaction vessel has a significant impact on product quality. Therefore, cleaning this type of equipment is very important. Most existing cleaning equipment uses spray guns or automatic cleaning pipelines to reach into the reaction vessel and clean the inside of the reaction vessel with high-pressure water jets. However, this cleaning method is more convenient for cleaning reaction vessels with relatively regular internal structures. But for reaction vessels with internal structures containing heating pipes, auxiliary material pipes, etc., the effect of spray guns or automatic cleaning is not very good. In such cases, manual entry into the reaction vessel and handheld cleaning devices are required.

[0003] Especially when producing high-viscosity products such as resins and adhesives, a lot of residue will adhere to the inside of the reactor after production. However, most existing handheld cleaning devices are high-pressure spray guns. Sometimes, in order to ensure the high pressure of the spray gun, the delivery pressure of the water pump can only be increased to remove the residue. However, for some residues between the heating tube and the reactor, high-pressure spray gun cleaning can only clean the front side. Since the high-pressure spray gun is a straight rod, it is inconvenient to bend it during cleaning, so it cannot clean the gaps thoroughly. In addition, the water droplets and small particles splashed by the high-pressure spray gun can cause injury to the operator's face and arms, causing strong discomfort. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies where high-pressure spray guns used for cleaning reactors cannot be bent as needed to clean crevices properly and splashed impurities can cause injury to operators. This invention provides a handheld reactor cleaning device.

[0005] The present invention is achieved through the following technical solution: a handheld reactor cleaning device, including a handheld part, the handheld part being provided with a control device for controlling the on and off, a pressurizing device being provided on the upper part of the handheld part, the pressurizing device including a mixing tank provided on the upper part of the handle, the output end of the pressurizing device being connected to a protective device for protecting the human body, the protective end of the protective device being provided with an output device, the output device including a cleaning device and a sweeping device.

[0006] Furthermore, the handheld part includes a handle, and the control device is located at the outlet of the mixing tank.

[0007] Furthermore, the inlet of the mixing tank is provided with a first pipe for connecting to a water circuit and a second pipe for connecting to a gas circuit, and a one-way valve is provided on the feeding path of the first pipe and the second pipe.

[0008] Furthermore, the second pipe is sleeved on the outside of the first pipe, and the first and second pipes extend into the interior of the mixing tank. The outlet of the first pipe is located at the bottom of the mixing tank, and the outlet of the second pipe is located at the top of the mixing tank.

[0009] Furthermore, a normally closed switch is provided at the upper part of the second pipe, and the operating end of the normally closed switch faces the control device and is on the operating path of the control device.

[0010] Furthermore, the cleaning device is a cleaning pipe connected to the output end of the mixing tank, and the working end of the cleaning pipe is provided with a rinsing element that can adjust the cleaning angle.

[0011] Furthermore, the cleaning device includes a drive tube disposed outside the cleaning tube, a protective device disposed outside the drive tube, and a cleaning component detachably disposed at the working end of the drive tube.

[0012] Furthermore, the drive tube is a pneumatic tube, and the protective device is a nozzle disposed on the outside of the drive tube, wherein the nozzle has multiple nozzles arranged in a ring along the vertical direction.

[0013] Furthermore, the cleaning component includes a connecting tube, which is connected to the drive tube via a quick-connect plug, and a brush head is provided at the working end of the connecting tube.

[0014] The beneficial effects of this invention are as follows: the drive tube is sleeved outside the cleaning tube, reducing the space occupied; the drive tube is a pneumatic tube, and the drive tube is connected to the second pipe through a bypass pipe; the protective device is a nozzle set outside the drive tube, with multiple nozzles arranged in a ring along the vertical direction; the nozzle has a conical cavity in the direction of incoming air to increase the gas capacity; the ring-shaped nozzles form a circular gas protective barrier in front of the operator, blocking water mist and fine particles splashed towards the operator during rinsing, or changing the splash direction and reducing the impact force of the particles, ensuring the comfort of the operator; at the same time, it provides continuous air pumping in the closed space, so that the inside of the reactor has the oxygen content required for operation, ensuring the safety of the operator.

[0015] The auxiliary rod stabilizes the nozzle after changing the spray angle, ensuring structural strength and improving the rinsing effect. It has a more direct rinsing effect on the residue inside the gaps between the auxiliary pipes inside the reactor. The adjustment method is simple and easy to control, convenient to use, and occupies little space. The impeller inside the connecting pipe drives the shaft of the brush head to rotate, providing power to the brush head. The brush head can remove stubborn impurities on the reactor, assisting the nozzle rinsing. The brush head is also easy to replace, greatly improving the cleaning efficiency and effect inside the reactor. Attached Figure Description

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Example 1

[0027] like Figure 1-7 As shown: A handheld reactor cleaning device includes a handheld part, which includes an ergonomic handle 1. The handheld part is equipped with a control device for controlling the on / off state. A pressurizing device is provided on the upper part of the handheld part. The pressurizing device includes a mixing tank 2 located on the upper part of the handle 1. The control device is located at the outlet of the mixing tank 2 and is a lever 4. When in use, pressing the lever 4 opens the outlet of the mixing tank 2, causing the water inside the mixing tank 2 to spray out. As this is a mature technical structure, the applicant will not elaborate further here.

[0028] The mixing tank 2 has a first pipe 101 for connecting to a water path and a second pipe 102 for connecting to a gas path at its inlet. One-way valves are installed along the feeding paths of both pipes 101 and 102 to ensure the correct conveying direction of the water and gas and prevent backflow. The second pipe 102 is fitted over the first pipe 101. Both pipes extend into the mixing tank 2. The outlet of the first pipe 101 is located at the bottom of the mixing tank 2, and the outlet of the second pipe 102 is located at the top of the mixing tank 2. A constant pressure valve is installed at the top of the second pipe 102. The normally closed switch 5 is positioned so that its operating end faces the lever 4 and is on the movement path of the lever 4. The first pipe 101 and the second pipe 102 are connected, reducing the volume occupied and lowering the manufacturing difficulty. The normally closed switch 5 is a control block installed on the first and second pipes. The second pipe 102 at the control block is sealed between the outer wall of the first pipe 101 and the second pipe 102. A notch is opened on one side of the lever 4, and a spring rod 504 is laterally slidably installed inside the notch. The bottom of the spring rod 504 has a sleeve 501, which is laterally positioned inside the first pipe 101. The internal seal is such that the first pipe 101 is connected to the outer wall of the sleeve 501, ensuring that water can smoothly enter the mixing tank 2. A spring 502 is wound around the bottom of the spring rod 504, ensuring that the spring rod 504 always has an outward pressure. A baffle 503 is provided at the notch of the spring rod 504, with multiple through holes 505 on the outer side of the baffle 503. The tail of the baffle 503 near the first pipe 101 is a closed flat plate. Sealing rings are bonded to the through holes 505 and the closed hinge of the baffle 503. When in use, the lever 4 is moved, firstly causing water to flow into the mixing tank 2. Water connected to the first pipe 101 is output to the outside through the cleaning pipe 301. When cleaning the inside of the reactor, the operator holds the handle 1 and uses high-pressure water to rinse the inside of the reactor. The mixing tank 2 is installed on the top of the handle 1. For some stubborn residues inside the reactor, simply press the lever 4 to make the lever 4 abut against the spring lever 504. Press the spring lever 504 down further and insert the side of the lever with the through hole 505 into the notch, so that the second pipe 102 is connected to the mixing tank 2. The compressed air pressure is achieved by using a piston compressor to reach 2.At approximately 5 MPa, because the top of the second pipe 102 is installed at the top of the mixing tank 2, the gas entering the mixing tank 2 pressurizes the water below, increasing the pressure at the outlet during cleaning. Simply repeatedly squeezing and releasing the lever 4 causes the spring lever 504 to repeatedly open and close, repeatedly pressurizing the inside of the mixing tank 2. After a batch of pressurized water is sprayed out, the baffle 503 closes the second pipe 102, allowing water from the first pipe 101 to enter the mixing tank 2. The squeezed-out air and water create a pulsed cleaning effect inside the reactor. Once water flows continuously from the cleaning pipe 301, continue pressing the lever 4 to pressurize the water inside the mixing tank 2, forming a high-pressure water flow for rinsing. The control method is simple, requiring no further operation by personnel in a confined space, improving cleaning effectiveness and ensuring optimal performance.

[0029] The output end of the pressurizing device is connected to a protective device for human protection. The protective device has an output device at its protective end, which includes a cleaning device and a sweeping device. The cleaning device is a cleaning pipe 301 connected to the output end of the mixing tank 2. The working end of the cleaning pipe 301 is equipped with a flushing element 6 that can adjust the cleaning angle. The flushing element 6 is connected to the cleaning pipe 301 via a quick-connect plug, and high-pressure water is sprayed out through the cleaning pipe 301. The flushing element 6 includes an internal flexible hose 601, with multiple movable shells 602 movably sleeved on the outside of the flexible hose 601. The cross-section of each movable shell 602 is trapezoidal, and adjacent movable shells 602 are nested together. An annular locking seat 603 is provided on the inner wall of each movable shell 602. Multiple protruding ribs 604 that mate with the locking seat 603 are provided on the protruding sidewall of the movable shell 602 to the right. Multiple ribs 604 are provided along the length direction, and the front end of each rib 604 is arc-shaped. To control the spray direction, the nozzle can be manually changed. The hose 601 is interlocked to maintain stability. Two auxiliary rods 605 are hinged to both sides of the nozzle. Multiple hooks are provided at the other end of the auxiliary rods 605. Two pull hooks 606 are installed on both sides of the end of the cleaning pipe 301. When the nozzle is kept horizontal, multiple movable shells 602 are pressed together by the pull hooks 606 to keep the nozzle spraying stably. When it is necessary to change the spray angle, simply loosen the auxiliary rods 605 and the pull hooks 606 and manually change the spray angle. In the case of a reactor with heating or auxiliary pipes, the nozzle is usually changed to face downwards or upwards. After changing the angle, multiple fixing holes 608 are opened on the auxiliary rods 605. The fixing holes 608 are connected to the positioning post 607 in front of the pull hooks 606. The auxiliary rods 605 stabilize the nozzle after changing the spray angle, ensuring structural strength and improving the rinsing effect. In particular, it has a more direct rinsing effect on the residue inside the gaps between the auxiliary pipes inside the reactor. The adjustment method is simple and easy to control, convenient to use, and occupies little space.

[0030] The cleaning device includes a drive pipe 302 located outside the cleaning pipe 301, and a protective device located outside the drive pipe 302. A cleaning component is detachably mounted on the working end of the drive pipe 302. The drive pipe 302 is sleeved around the outside of the cleaning pipe 301 to reduce space occupation. The drive pipe 302 is a pneumatic pipe, and it is connected to the second pipe 102 via a bypass pipe 303. The inlet of the bypass pipe 303 is located below the spring rod 504, ensuring that the drive pipe 302 remains continuously ventilated and is unaffected by the spring rod 504. The protective device is located outside the drive pipe 302. The air nozzle 3 has multiple nozzles arranged in a vertical ring. The air nozzle 3 has a conical cavity in the direction of incoming air to increase the gas capacity. The ring-shaped nozzles form a circular gas protection barrier in front of the operator, which blocks water mist and fine particles splashed towards the operator during the flushing process, or changes the splash direction and reduces the impact force of the particles, ensuring the comfort of the operator. At the same time, it provides a continuous air pump in the closed space, so that the inside of the reactor has the oxygen content required for operation, ensuring the safety of the operator.

[0031] The cleaning component includes a connecting pipe that connects to the drive pipe 302 via a quick-connect fitting. A brush head 305 is provided at the working end of the connecting pipe. When the connecting pipe is not inserted, the quick-connect fitting remains closed, allowing air to escape only through the nozzle. When the connecting pipe is inserted into the drive pipe 302, the impeller 304 inside the connecting pipe drives the shaft of the brush head 305 to rotate, providing power to the brush head 305. The brush head 305 can remove stubborn impurities from the reactor, assisting the nozzle in rinsing. Furthermore, the brush head 305 is easy to replace, greatly improving the cleaning efficiency and effect inside the reactor.

[0032] Finally, it is worth mentioning that a normally closed switch is installed at the upper part of the second pipeline. The operating end of this normally closed switch faces the control device and is in the operating path of the control device. When the operator presses the control device, the normally closed switch is opened, thereby allowing the gas path to open and further generating high-pressure cleaning fluid.

[0033] In summary, the handheld reactor cleaning equipment provided in this embodiment has a simple structure, is easy to operate, and can efficiently complete the cleaning of reactors, thus having high practical value.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
