[0038] The following is combined with Figures 1-3 The following describes some embodiments of the present invention in detail. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0039] Firstly, this utility model provides a cleaning device for cleaning the stirring paddle 14, such as... Figure 1 As shown, it includes a cleaning agent tank; the cleaning agent tank includes a first tank body 3, a conveying pipeline 4, a power piston 2, and a piston power device 1; one end of the conveying pipeline 4 is connected to the first tank body 3, and the other end of the conveying pipeline 4 is used to connect to a stirring tank; the piston power device 1 is connected to the power piston 2 and is used to provide the power piston 2 with moving power; the power piston 2 is disposed in the first tank body 3 and can apply pressure to the cleaning agent in the first tank body 3, so that the cleaning agent enters the stirring tank through the conveying pipeline 4.
[0040] In this embodiment, the cleaning agent is placed inside the first vessel body 3. The power piston 2 is driven by the power device to move inside the first vessel body 3 to squeeze the cleaning agent. The cleaning agent is squeezed out from the first vessel body 3 through the delivery pipeline 4 and enters the mixing vessel for cleaning the mixing vessel.
[0041] After cleaning the mixing vessel or after cleaning the mixing vessel once, start the piston power device 1 to drive the power piston 2 to move in the opposite direction, so that a negative pressure is formed in the first vessel body 3, which draws back the cleaning agent in the mixing vessel. After cleaning is completed or after replacing with new cleaning agent, clean again to ensure the cleaning effect.
[0042] In an optional embodiment, a one-way filter is provided between the first vessel body 3 and the conveying pipeline 4 to filter the returned cleaning agent.
[0043] In this embodiment, the one-way filtration device ensures that impurities in the cleaning agent can only enter the first vessel 3 from the stirring vessel, but cannot enter the stirring vessel from the first vessel 3.
[0044] After cleaning the mixing vessel once, the used cleaning agent flows from the mixing vessel into the first vessel body 3 under the action of the power piston 2. Then, the piston power device 1 and the power piston 2 pressurize the first vessel body 3, and the cleaning agent is transported back into the mixing vessel. At this time, the impurities in the cleaning agent in the first vessel body 3 are filtered by the one-way filter device, and the cleaning agent entering the mixing vessel is clean. It can clean the mixing blade 14 in the mixing vessel again, improve the utilization rate of the cleaning agent, and at the same time, there is no need to replace the cleaning agent, thus improving the cleaning efficiency.
[0045] In an optional embodiment, the unidirectional filtration device includes a forward pipeline 9, a return filter cartridge, a first control valve 10, a second control valve 11, and a third control valve 12; the forward pipeline 9 and the return filter cartridge are arranged in parallel; the first control valve 10 is disposed on the forward pipeline 9, the second control valve 11 is disposed upstream of the return filter cartridge during return flow, and the third control valve 12 is disposed at the bottom of the return filter cartridge.
[0046] Specifically, in this embodiment, the forward pipeline 9 is controlled by the first control valve 10. When the first control valve 10 is open, the cleaning agent in the first vessel 3 can enter the mixing vessel through the forward pipeline 9. When reflux is required, the first control valve 10 is closed and the second control valve 11 is opened, allowing the reflux filter cartridge to filter the cleaning agent. Only the filtered cleaning agent can enter the first vessel 3 through the delivery pipeline 4. When there are many impurities in the reflux filter cartridge, the third control valve 12 is opened to clean the impurities inside the reflux filter cartridge. When the reflux filter cartridge is not being cleaned, the third control valve 12 is normally closed.
[0047] In this embodiment, the reflux filter cartridge includes a cylinder body 7 and a filter screen. Both ends of the cylinder body 7 are provided with inlets and outlets for the cleaning agent. A filter screen 8 is installed inside the cylinder body 7, dividing the inside of the cylinder body 7 into two parts, thereby achieving the filtration of the cleaning agent.
[0048] In an optional embodiment, the power piston 2 is provided with a liquid injection valve 5, which is used to control the communication state between the inside and outside of the first vessel body 3.
[0049] In this embodiment, a liquid injection valve 5 is provided on the power piston 2. When the pressure inside the first vessel 3 is too high, the pressure can be released by opening the liquid injection valve 5, thereby ensuring the safety of the first vessel 3.
[0050] At the same time, cleaning agent can also be injected into the first vessel body 3 through the injection valve 5.
[0051] Secondly, this utility model provides a stirring vessel, such as... Figure 2 As shown, it includes a second vessel body 15, a stirring mechanism, and a cleaning device as described in any of the preceding embodiments; the stirring mechanism is disposed on the second vessel body 15 and is capable of stirring the substances inside the second vessel body 15; the conveying pipeline 4 is connected to the interior of the second vessel body 15 and is used to convey cleaning agent into the interior of the second vessel body 15.
[0052] Specifically, in an optional embodiment, the stirring mechanism includes a lower stirring structure and an upper stirring structure; the stirring paddle 14 of the lower stirring structure is disposed at the bottom inside the second vessel body 15, and the first power unit 17 of the lower stirring structure is disposed outside the second vessel body 15; one end of the stirring rod 18 of the upper stirring structure is inserted into the second vessel body 15 from the upper end of the second vessel body 15, and the upper end of the stirring rod 18 is connected to the second power unit 20.
[0053] In this embodiment, the stirring paddle 14 is located at the lower part of the second vessel body 15. When cleaning the stirring paddle 14, the cleaning agent is driven by the power piston 2 and enters the second vessel body 15 from the first vessel body 3 through the delivery pipe 4. The first power device 17 drives the stirring paddle 14 to rotate, and the stirring paddle 14 is cleaned by the cleaning agent entering the second vessel body 15.
[0054] When the cleaning agent contains a certain amount of impurities such as glue, which reduces the cleaning effect, the cleaning agent flows back from the second vessel 15 to the first vessel 3 under the action of the power piston 2. Then, under the action of the one-way filter device, it is filtered and re-enters the second vessel 15 to clean the stirring paddle 14 again.
[0055] In this embodiment, the first power device 17 is an electric motor.
[0056] Similarly, the cleaning process of the upper stirring structure is the same as that of the stirring paddle 14.
[0057] In an optional embodiment, a cleaning hood 19 is also included, which is used to isolate the first vessel body 3 from the second power unit 20.
[0058] Normally, cleaning the agitator 14 involves pouring cleaning agent into the mixing tank and stirring it first. Then, a cloth soaked in the cleaning agent is used to wipe the stubborn glue on the agitator 14. To save on the amount of cleaning agent used and reduce contact between the cleaning agent and the human body, a nozzle with a bulb is designed. The cleaning agent is sprayed from the nozzle to rinse the agitator 14 from various angles, and then it is wiped with a cloth. This method greatly reduces the amount of cleaning agent used.
[0059] However, due to the large number of screws connecting the agitator 14 and the top cover, there are many dead corners. The top cover and the upper motor are not sealed. As the agitator 14 rotates, the cleaning agent splashes onto the top cover, causing more contamination and making cleaning more difficult. Similarly, because the top cover is not sealed, the nozzle cannot spray the cleaning agent upwards. Furthermore, the cleaning agent has low solubility for acrylic resin, making it difficult to wash away the residual glue on the agitator 14 using only the nozzle. Also, the nozzle usually protrudes significantly from the mixing vessel, hindering the rotation of the agitator 14. Alternatively, the agitator 14 may splash the cleaning agent onto the top cover when it rotates.
[0060] In this embodiment, the stirring paddle 14 may also encounter the above-mentioned problems during cleaning. Therefore, in order to solve the above problems, a cleaning cover 19 is added in this embodiment. The cleaning cover 19 isolates the first vessel body 3 from the second power device 20, thereby preventing impurities or cleaning agents on the stirring paddle 14 from splashing onto the top cover plate.
[0061] The cleaning hood 19 can be connected to the second vessel body 15 to separate the parts that need to be cleaned from the parts that do not need to be cleaned.
[0062] In this embodiment, the second power device 20 is a motor, the cleaning cover 19 is disposed on the motor protective cover 21, and there is a silicone pad 24 between the cleaning cover 19 and the motor protective cover 21. The silicone pad 24 achieves a tight fit between the cleaning cover 19 and the motor protective cover 21, that is, the cleaning cover 19 is disposed at the opening of the motor protective cover 21 and is embedded in the motor protective cover 21.
[0063] Specifically, in this embodiment, such as Figure 3 As shown, the cleaning cover 19 is provided with a stirring rod hole 23, which matches the stirring rod 18 of the upper cleaning structure.
[0064] Specifically, the cleaning cover 19 can be divided into two parts, and is equipped with a latch 25, a stirring rod hole 23, a silicone pad 24, a pressure relief valve 22, etc. The cleaning cover 19 is mostly made of stainless steel, with a diameter slightly smaller than the motor protection cover 21. It has a silicone pad 24 around its perimeter, and its total diameter is larger than the motor protection cover 21 to facilitate the fixing and sealing of the cleaning cover 19. A stirring rod hole 23 is located at the corresponding position of the stirring rod 18, filled with silicone, with a diameter slightly smaller than the stirring rod 18, to ensure the sealing of the cleaning cover 19. After the cleaning cover 19 is installed, the two pieces can be fixed together by the latch 25 to prevent them from falling off.
[0065] In an optional embodiment, the cleaning hood 19 is provided with a pressure relief valve 22.
[0066] In this embodiment, a pressure reducing valve is provided on the cleaning cover 19 to prevent the motor from generating high pressure inside the motor protection cover 21 due to heat.
[0067] In an optional embodiment, a reflux valve 13 is provided at the bottom of the second vessel 15, the reflux valve 13 being used to control the connection between the bottom of the second vessel and the conveying pipeline 4.
[0068] In this embodiment, when the stirring paddle 14 is stirring, the reflux valve 13 is closed to prevent the cleaning agent in the second vessel 15 from flowing back, and also to prevent substances such as glue from entering the delivery pipeline 4 when the stirring paddle 14 is working normally.
[0069] When cleaning agent backflow is required, the backflow valve 13 is opened, and the cleaning agent in the second vessel 15 returns to the first vessel 3 through the delivery pipeline 4.
[0070] In an optional embodiment, a nozzle 16 is provided on the side wall of the second vessel 15, and the nozzle 16 is connected to the conveying pipeline 4.
[0071] In this embodiment, the nozzle 16 is disposed on the side wall of the second vessel 15, and the delivery pipeline 4 is connected to the nozzle 16. When the cleaning agent enters the second vessel 15 under the action of the power piston 2, it will be sprayed inward from the side wall of the second vessel 15 to achieve preliminary rinsing of the stirring paddle 14.
[0072] As can be seen from the above embodiments, in the cleaning device of this utility model, the power piston 2 has a liquid injection valve 5. When cleaning is required, the return valve 13, the liquid injection valve 5, the second control valve 11 and the third control valve 12 are closed, and the connecting valve 6 and the first control valve 10 are opened. At this time, the hydraulic rod moves downward, and the cleaning agent is sprayed out from the nozzle under pressure to rinse the glue residue on the stirring paddle 14. If the pressure inside the second vessel 15 is too high, the pressure relief valve 22 will release the gas. After the cleaning agent in the second vessel 15 accumulates to a certain position, the motor is turned on, and the stirring paddle 14 starts to move under the drive of the pulley, continuously rinsing the glue.
[0073] After cleaning, slightly lift the stirring paddle 14, open the reflux valve 13 and the second control valve 11, close the liquid injection valve 5 and the first control valve 10, and the power piston 2 moves upward; under negative pressure, the cleaning agent returns to the first vessel 3 through the filter screen 8, and all impurities can remain in the cylinder 7; after completion, close the reflux valve 13 and the first control valve 10.
[0074] The connecting valve 6 is used to control the entry and exit of the cleaning agent in the first vessel 3. Whether the cleaning agent is output or returned, the connecting valve 6 needs to be opened. After the connecting valve 6 is closed, it can be ensured that the internal liquid will not leak.
[0075] The beneficial effects of this utility model embodiment are:
[0076] Cleaning agent is supplied to the mixing tank through a cleaning agent container. After cleaning, the cleaning agent containing impurities in the mixing tank is recovered, and new cleaning agent is injected for repeated cleaning, thereby improving the cleaning efficiency of the mixing blade 14 and reducing the cleaning difficulty. The above description is only a preferred embodiment of this utility model and is not intended to limit this utility model. For those skilled in the art, this utility model can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
