Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, and more particularly to a cleaning device for a high-pressure homogenizer. Background Technology

[0002] High-shear dispersion emulsification is the process of efficiently, rapidly, and uniformly introducing one or more phases (liquid, solid, gas) into another immiscible continuous phase (usually a liquid). Under normal circumstances, the phases are immiscible. When external energy is input, the two materials recombine to form a homogeneous phase. Due to the high tangential velocity and strong kinetic energy generated by the high-speed rotation of the rotor, the material is subjected to intense mechanical and hydraulic shearing, centrifugal extrusion, liquid layer friction, impact tearing, and turbulence within the narrow gap between the stator and rotor, forming suspensions (solid / liquid), emulsions (liquid / liquid), and foams (gas / liquid). This allows the immiscible solid, liquid, and gas phases to be instantly, uniformly, and finely dispersed and emulsified under the combined action of appropriate mature processes and suitable additives.

[0003] Existing cleaning equipment typically uses warm water pumped in through the inlet pipe to clean high-pressure homogenizers. This requires filling the homogenizer's tank with water before the water flow can reach the outside of the homogenizing valve, wasting water resources and making it inconvenient to clean multiple homogenizers one by one. This results in low cleaning efficiency for workshops with multiple homogenizers. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cleaning device for a high-pressure homogenizer, thereby solving the problem of low cleaning efficiency between multiple homogenizers in existing technologies.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cleaning device for a high-pressure homogenizer includes a mobile vehicle, the mobile vehicle being equipped with a rinsing device, the rinsing device including a water tank, the water tank being fixedly connected to the mobile vehicle, and a lifting cover being provided at the bottom of the mobile vehicle;

[0007] A water supply pipe is fixedly connected to one side of the water tank, and a telescopic hose is fixedly connected to the end of the water supply pipe away from the water tank. A transverse connector is fixedly connected to the end of the telescopic hose, and the transverse connector moves horizontally when the lifting cover descends.

[0008] Preferably, the rinsing device further includes a lifting cylinder, the telescopic rod of which is fixedly connected to the upper side of the lifting cover.

[0009] Preferably, a support ring is provided on the outer circle of the transverse joint, and two guide rods are fixedly connected to one side of the support ring. The guide rods pass through the side plate of the mobile vehicle and are slidably connected to it.

[0010] Preferably, a support rod is fixedly connected to one side of the lifting cover, the support rod is provided with a through groove, a slider is slidably connected in the through groove, a support spring is fixedly connected to one end of the slider and the through groove, a hanging rod is fixedly connected to the bottom of the slider, a sleeve is fixedly connected to the upper side of the support ring, the hanging rod extends into the sleeve and is slidably connected, a crossbar is fixedly connected to the upper side of the slider, a roller is rotatably connected to the end of the crossbar, and a limiting block is fixedly connected to one side of the side plate of the moving vehicle. The upper part of the side of the limiting block is sloping and the lower part is vertical, and the roller presses against the side of the limiting block.

[0011] Preferably, the tapered end of the transverse connector is made of rubber, and a support wheel is rotatably connected to the upper side of the transverse connector.

[0012] Preferably, the bottom of the lifting cover is rotatably connected to a support plate, and the bottom edge of the support plate is arrayed with multiple vertical inclined plates.

[0013] Preferably, a suspension rod is fixedly connected to the side of the lifting hood away from the support rod, and a water spray plate is fixedly connected to the bottom of the suspension rod. The water spray plate is connected to the inner cavity of the lifting hood through a water supply pipe.

[0014] The advantages of this invention are as follows: The cleaning device for a high-pressure homogenizer provided by this invention involves flipping the top cover of the high-pressure homogenizer to be cleaned, exposing the homogenizing valve. After moving the mobile cart to the position of the high-pressure homogenizer, the observation window on the side plate shows whether the transverse connector is coaxial with the liquid inlet pipe of the homogenizing valve. After the transverse connector is coaxial with the liquid inlet pipe, the lifting cylinder covers the outside of the homogenizing valve with the top cover to form a seal. The water pump in the water tank works to pump warm water into the homogenizing valve through the transverse connector and fill the cavity between the lifting cover and the top cover. On the one hand, it can rinse the homogenizing valve, and on the other hand, the cavity between the lifting cover and the top cover covers the outside of the homogenizing valve, and the cleaning is concentrated in a small area, which can thoroughly clean the inside and outside of the homogenizing valve, while also saving water. The high-pressure homogenizer is cleaned sequentially through the above steps. The cleaning switching between two high-pressure homogenizers is convenient and fast, thereby improving the cleaning efficiency.

[0015] This invention utilizes a roller that moves down the slope of a limiting block. As the slope gradually increases, the crossbar moves laterally, pushing the slider horizontally and compressing the support spring. After the elastic rubber transverse connector aligns with the inlet pipe, the roller moves from the vertical surface of the limiting block, and the lifting cylinder covers the reversed top cover of the lifting hood. This allows for concentrated cleaning of specific areas. This design ensures the transverse connector moves horizontally as the lifting hood descends, maintaining structural stability. Furthermore, after the transverse connector aligns with the inlet pipe, the support wheel on the upper side of the transverse connector supports the top cover, preventing excessive downward stroke of the lifting cylinder due to air pressure fluctuations during cylinder depressurization. This avoids the top cover rotating more than 180°, leading to leakage due to poor sealing at the bottom of the lifting hood, thus ensuring stable and reliable device operation.

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the invention 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 and not intended to limit the invention.

[0023] Example 1

[0024] like Figure 1-6 As shown, the present invention provides a cleaning device for a high-pressure homogenizer, including a mobile vehicle 1, the mobile vehicle 1 being equipped with a rinsing device 2, the rinsing device 2 including a water tank 21, the water tank 21 being fixedly connected to the mobile vehicle 1, and a lifting cover 22 being provided at the bottom of the mobile vehicle 1;

[0025] A water supply pipe 23 is fixedly connected to one side of the water tank 21. A telescopic hose 24 is fixedly connected to the end of the water supply pipe 23 away from the water tank 21. A transverse connector 25 is fixedly connected to the end of the telescopic hose 24. The tapered end of the transverse connector 25 is made of rubber. A support wheel 251 is rotatably connected to the upper side of the transverse connector 25. The transverse connector 25 moves horizontally when the lifting cover 22 descends.

[0026] The flushing device 2 also includes a lifting cylinder 26. The telescopic rod of the lifting cylinder 26 is fixedly connected to the upper side of the lifting cover 22. A support ring 27 is provided on the outer circle of the transverse connecting joint 25. Two guide rods 28 are fixedly connected to one side of the support ring 27. The guide rods 28 pass through the side plate 11 of the mobile vehicle 1 and are slidably connected to it.

[0027] This invention is applicable to the cleaning of multiple high-pressure homogenizers 10 in a batch chemical plant. Multiple high-pressure homogenizers 10 are arranged in a row with channel steel embedded in their bottom surfaces on both sides. The moving wheels of the mobile cart 1 enter the channel steel to form a limiting position. First, the top cover 20 of the high-pressure homogenizer 10 to be cleaned is rotated 180 degrees, exposing the homogenizing valve 40. After the mobile cart 1 is moved to the position of the high-pressure homogenizer 10, the observation window 12 on the side plate 11 is used to observe whether the transverse connecting joint 25 is coaxial with the liquid inlet pipe 30 of the homogenizing valve 40. After the transverse connecting joint 25 is coaxial with the liquid inlet pipe 30, the lifting cylinder 26 covers the lifting cover 22 outside the homogenizing valve 40 and forms a seal with the top cover 20. The water pump in the water tank 21 then operates. Warm water is pumped into the homogenizing valve 40 through the transverse connector 25, filling the cavity between the lifting cover 22 and the upper cover 20. This serves two purposes: firstly, it flushes the homogenizing valve 40; secondly, the cavity between the lifting cover 22 and the upper cover 20 encloses the outside of the homogenizing valve 40, concentrating the cleaning in a small area. This allows for thorough cleaning of both the inside and outside of the homogenizing valve 40, while also saving water. The mobile vehicle 1 of this invention can clean multiple high-pressure homogenizers 10 one by one. During cleaning, the liquid supply pipe on the inlet pipe 30 is removed. The high-pressure homogenizers 10 are cleaned sequentially through the above steps. The switching between two high-pressure homogenizers 10 is convenient and quick, thereby improving cleaning efficiency.

[0028] In this embodiment, the horizontal movement of the transverse coupling 25 can be achieved by a cylinder, hydraulic cylinder, electric push rod, or manual pushing.

[0029] Example 2

[0030] like Figure 1-6 As shown, in Embodiment 1, since the mobile vehicle 1 needs to move frequently between multiple high-pressure homogenizers 10, its results need to be relatively stable. In Embodiment 1, there is already a lifting cylinder 26. If a horizontal cylinder is added in the lateral direction, it will involve adding air passages and control elements to control the movement of the two cylinders respectively.

[0031] To optimize the above design, a support rod 3 is fixedly connected to one side of the lifting cover 22. The support rod 3 is provided with a through groove 31. A slider 32 is slidably connected in the through groove 31. A support spring 33 is fixedly connected to one end of the slider 32 and the through groove 31. A hanging rod 34 is fixedly connected to the bottom of the slider 32. A sleeve 35 is fixedly connected to the upper side of the support ring 27. The hanging rod 34 extends into the sleeve 35 and is slidably connected to it, so as to extend and retract in coordination with the lifting cover 22. A crossbar 36 is fixedly connected to the upper side of the slider 32. A roller 37 is rotatably connected to the end of the crossbar 36. A limiting block 38 is fixedly connected to one side of the side plate 11 of the moving vehicle 1. The upper part of the side of the limiting block 38 is sloping and the lower part is vertical. The roller 37 presses against the side of the limiting block 38.

[0032] After adopting the solution in Embodiment 2, only the lifting cylinder 26 needs to push the lifting cover 22 down. During this process, the roller 37 moves down the slope of the limiting block 38. As the slope gradually increases, the crossbar 36 moves laterally, pushing the slider 32 to move horizontally and compressing the support spring 33. After the elastic rubber transverse connector 25 is connected to the liquid inlet pipe 30, the roller 37 moves from the vertical surface of the limiting block 38. Then, the lifting cylinder 26 covers the lifting cover 22 with the reversed upper cover 20, and then the local area is cleaned. During cleaning, this design allows the transverse connector 25 to move horizontally when the lifting hood 22 descends, ensuring structural stability. After the transverse connector 25 connects to the inlet pipe 30, the support wheel 251 on the upper side of the transverse connector 25 supports the upper cover 20, preventing excessive downward stroke of the lifting cylinder 26 due to air pressure fluctuations when the lifting hood 22 is pressed down. This would cause the upper cover 20 to rotate more than 180°, resulting in poor sealing at the lower opening of the lifting hood 22 and leakage, thus ensuring the stable and reliable operation of the device.

[0033] Example 3

[0034] like Figure 1-6 As shown, the bottom of the lifting hood 22 is rotatably connected to the support plate 4, and the bottom edge of the support plate 4 is arranged with multiple vertical inclined plates 5. The bottom extrusion groove 41 of the homogenizing valve 40 is... Figure 4 The spiral shape of the vertical inclined plate 5 corresponds to the extrusion groove 41, which sprays water. Similar to the principle of a waterwheel impeller, the support plate 4 rotates with the vertical inclined plate 5, causing the water to rotate in a local area. The rotating water flow makes it easier to rinse the outside of the homogenizing valve 40, thus cleaning it more thoroughly.

[0035] The lifting cover 22 is fixedly connected to the suspension rod 6 on the side away from the support rod 3. The bottom of the suspension rod 6 is fixedly connected to the water spray plate 7. The water spray plate 7 is connected to the inner cavity of the lifting cover 22 through a water supply pipe.

[0036] The water flow after being rotated and rinsed inside the lifting hood 22 is sprayed into the tank of the high-pressure homogenizer 10 through the water supply pipe and the spray plate 7, which saves water. The structure inside the tank is simpler than that of the homogenizer valve 40. It does not need to be limited to rinsing in a small area like the homogenizer valve 40, thus rationally allocating cleaning resources and achieving efficient cleaning.

[0037] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
