Description

Technical Field

[0001] This utility model belongs to the field of industrial cleaning technology, and specifically relates to a constant temperature circulating cleaning device for ointment filling pipelines. Background Technology

[0002] The ointment filling pipeline cleaning device is a specialized device for removing residual ointment from the filling system. It uses a pump to flow cleaning fluid within a closed pipeline, combined with heating, chemical cleaning agents, and directional flushing functions, to achieve efficient cleaning of the pipeline's inner wall, ensuring the hygiene and smooth flow of the filling pipeline.

[0003] However, traditional ointment filling pipeline cleaning devices lack constant temperature circulation function, which will cause the cleaning fluid temperature to fluctuate, reduce the dissolution efficiency of high viscosity ointments, and easily cause residue on the inner wall of the pipeline. At the same time, each cleaning requires the replacement of the cleaning fluid, resulting in a serious waste of water resources and chemical reagents.

[0004] To address the issues mentioned in the background above, a constant temperature circulating cleaning device for ointment filling pipelines is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a constant temperature circulating cleaning device for ointment filling pipelines, which has the advantage of maintaining constant temperature and circulating cleaning.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a constant temperature circulating cleaning device for ointment filling pipeline, comprising an inner shell, an outer shell sleeved on the surface of the inner shell, a partition plate welded in the middle of the inner wall of the inner shell, a through groove opened at the center of the top of the partition plate, sliding grooves opened on both sides of the bottom of the partition plate, sliding rods slidably sleeved inside the sliding grooves, floats welded to the bottom of the opposite side of the two sliding rods, float plugs welded to the top of the floats, a heating tube embedded in the bottom of the inner wall of the outer shell, a heat insulation tube embedded in the bottom of the inner wall of the outer shell, and a circulation mechanism provided on the left side of the bottom of the inner shell.

[0007] The above technical solution involves an internal cleaning solution separated into upper and lower layers by a partition plate. The upper layer is a heating layer, and the lower layer is an insulation layer. During cleaning of the filling pipes, the cleaning solution enters the upper layer, is heated by the heating pipe, and then enters the through-channel. From there, it enters the lower layer and is kept warm by the insulation pipe, preparing for circulating cleaning. Once the cleaning solution enters the lower layer, a float moves upward due to the buoyancy of the solution. A sliding rod and groove limit the movement of the float. When the cleaning solution in the lower layer reaches a certain level, the float moves a plug upward to block the bottom of the through-channel, cutting off the connection between the upper and lower layers. The cleaning solution in the lower layer is then extracted for cleaning. In the filling pipeline, as the lower layer of cleaning fluid decreases, the float moves downward, causing the float plug to move as well. The upper and lower layers are connected, continuing to supply cleaning fluid to the lower layer. The cleaning fluid returning to the upper layer is heated by the heating pipe before entering the lower layer and being kept warm by the insulation pipe for further cleaning. Maintaining a constant temperature for the cleaning fluid significantly improves the cleaning effect and safety of the ointment filling pipeline. The constant temperature ensures that the cleaning fluid maintains optimal solubility, effectively decomposing residual ointment, while avoiding thermal expansion and contraction of the pipeline caused by temperature fluctuations. This protects the pipeline's seal and prevents bacterial growth. The stable water temperature also ensures the activity of the cleaning fluid and reduces chemical residues.

[0008] The present invention is further configured such that the circulation mechanism includes a water pump, the water pump is embedded in the left side of the bottom of the inner shell, the top of the water pump is connected to a first water outlet pipe, and the top of the first water outlet pipe is connected to the left side of the bottom of the inner shell, the bottom of the water pump is connected to a second water outlet pipe, the left side of the top of the inner shell is connected to a water inlet pipe, the end of the second water outlet pipe away from the water pump is connected to a one-way valve, and the top of the one-way valve is connected to a filling pipe.

[0009] The above technical solution employs a circulation mechanism. When cleaning the filling pipeline is required, the water pump draws the constant-temperature cleaning solution from the lower layer through outlet pipe one to outlet pipe two. From outlet pipe two, the solution enters a one-way valve and then flows into the filling pipeline for cleaning. After cleaning the filling pipeline, the cleaning solution flows through the drainage system of the filling mechanism, enters the inlet pipe, and finally returns to the upper layer inside the inner shell for heating and circulation cleaning. The one-way valve prevents backflow of the cleaning solution and the entry of ointment into the cleaning device. The recycling of the cleaning solution significantly reduces water consumption and chemical consumption. Constant-temperature heating ensures that the cleaning solution maintains optimal activity, effectively dissolving stubborn ointment residues. Continuous circulation rinsing creates a dynamic cleaning effect, which more thoroughly removes deposits from dead corners of the pipeline compared to static soaking, thus improving overall cleaning efficiency and reducing operating costs.

[0010] The present invention is further configured such that an inlet pipe is provided on the right side of the top of the inner shell, and an outlet pipe is provided through and sleeved on the right side of the bottom of the inner shell.

[0011] The above technical solution allows for easy replacement of the cleaning fluid inside the device by setting up inlet and outlet pipes. The inlet pipe facilitates filling and is sealed with a sealing cap, while the outlet pipe facilitates discharge and is controlled by a valve.

[0012] The present invention is further configured such that valve plugs are hinged to the front and rear ends of the inner wall of the one-way valve.

[0013] The above technical solution involves installing a valve plug. When cleaning is required, the water pump draws out the cleaning fluid to open the valve plug and clean the filling pipeline. When cleaning is not needed, the valve plug naturally falls down to seal the bottom of the one-way valve, preventing backflow.

[0014] The present invention is further provided that a sealing ring is fitted at the bottom of the inner wall of the through groove.

[0015] The above technical solution, by setting a sealing ring and using an interference fit, has a dynamic sealing function to prevent cleaning fluid leakage.

[0016] The present invention is further configured such that an insulating sleeve is fitted onto the surface of the outer shell.

[0017] The above technical solution involves using an insulation jacket to keep the cleaning fluid inside the device warm.

[0018] The present invention is further provided that the front of the outer casing is provided with a transparent window.

[0019] The above technical solution allows for viewing the internal condition of the device and checking the cleaning fluid status to determine if it needs to be replaced by a transparent window.

[0020] The present invention is further provided that brackets are bolted to the bottom of both sides of the outer shell.

[0021] The above technical solution utilizes a support frame to stabilize the device.

[0022] In summary, this utility model has the following beneficial effects:

[0023] 1. This utility model can significantly improve the cleaning effect and safety of ointment filling pipelines by maintaining constant temperature circulation cleaning. The constant temperature state can ensure that the cleaning solution maintains the best solubility, effectively decomposes residual ointment, and avoids the thermal expansion and contraction of the pipeline caused by temperature fluctuations. It protects the pipeline's sealing performance and prevents bacterial growth. The stable water temperature can also ensure the activity of the cleaning solution and reduce chemical residues.

[0024] 2. This utility model significantly reduces water consumption and chemical consumption by recycling the cleaning solution. Constant temperature heating ensures that the cleaning solution maintains its optimal activity, effectively dissolving stubborn paste residues. Continuous cyclic rinsing creates a dynamic cleaning effect, which more thoroughly removes deposits from pipe dead corners compared to static soaking, thus improving overall cleaning efficiency and reducing operating costs.

[0031] The present invention will be further described in detail below with reference to the accompanying drawings.

[0032] Example 1:

[0033] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 A constant temperature circulating cleaning device for ointment filling pipelines includes an inner shell 1, an outer shell 2 fitted onto the surface of the inner shell 1, a partition plate 3 welded to the middle of the inner wall of the inner shell 1, a through groove 4 with a diameter of 50-80mm opened at the center of the top of the partition plate 3, and sliding grooves 5 opened on both sides of the bottom of the partition plate 3. Sliding rods 6 are slidably fitted inside the sliding grooves 5, and floats 7 are welded to the bottom of the opposite side of the two sliding rods 6. The device is made of PP and has a volume of 100-200cm³. 3The buoyancy is ≥5N, which is greater than 1.5 times the weight of the float plug 8, ensuring that the float plug 8 can reliably seal when the water level reaches 80%. The top of the float block 7 is welded with the float plug 8. The bottom of the inner wall of the outer shell 2 is embedded with a heating tube 9. The heating tube 9 is made of 304 stainless steel, with a power of 2-5kW and a diameter of 10-15mm. It is distributed in a ring to ensure that the upper water temperature is stable at 50-60℃. The bottom of the inner wall of the outer shell 2 is embedded with a heat insulation tube 10. The heat insulation tube 10 is made of aluminum silicate cotton, with a thickness of 50-80mm and a thermal conductivity of ≤0.03W / (m·K), so that the lower water temperature fluctuation is ≤±0.5℃. A circulation mechanism is set on the left side of the bottom of the inner shell 1. The inner shell 1 is filled with cleaning fluid, which is divided into upper and lower layers by the partition plate 3. The upper layer is the heating layer and the lower layer is the heat insulation layer. When cleaning the filling pipe 16, the filling pipe 1 After the cleaning solution enters the upper layer, it is heated by the heating pipe 9 and then enters the through-channel 4. From the through-channel 4, it enters the lower layer and is kept warm by the insulation pipe 10. The temperature is controlled within the range of 50±1℃ to prepare for the circulating cleaning. After the cleaning solution enters the lower layer, the float 7 moves upward due to the floating of the cleaning solution in the lower layer. The sliding bar 6 and the sliding groove 5 limit the movement of the float 7. When the cleaning solution in the lower layer reaches a certain level, the float 7 drives the float plug 8 to block the bottom of the through-channel 4, so that the upper and lower layers are disconnected. The cleaning solution in the lower layer is drawn out to clean the filling pipe 16. At this time, the cleaning solution in the lower layer decreases. The float 7 moves downward and drives the float plug 8 to move. The upper and lower layers are connected and the cleaning solution continues to be supplied to the lower layer. The cleaning solution that returns to the upper layer is heated by the heating pipe 9 and then enters the lower layer again and is kept warm by the insulation pipe 10 for cleaning. The cleaning solution is kept at a constant temperature.

[0034] refer to Figure 1 , Figure 2 An inlet pipe 17 is provided on the right side of the top of the inner shell 1, and an outlet pipe 18 is provided through and sleeved on the right side of the bottom of the inner shell 1. By providing the inlet pipe 17 and the outlet pipe 18, it is convenient to replace the cleaning fluid inside the device. The inlet pipe 17 is convenient for filling and is sealed by the sealing cap, while the outlet pipe 18 is convenient for discharging and is controlled by the valve.

[0035] refer to Figure 2 , Figure 3 , Figure 4 A sealing ring 20 is fitted at the bottom of the inner wall of the through groove 4. By setting the sealing ring 20 and fitting it with an interference fit, it has a dynamic sealing function to prevent the cleaning fluid from leaking. The material is food-grade silicone with a hardness of 60±5 Shore A.

[0036] refer to Figure 1 , Figure 2 , Figure 4 The outer shell 2 is fitted with an insulation sleeve 21, which can keep the cleaning fluid inside the device warm.

[0037] refer to Figure 1The front of the outer casing 2 is provided with a transparent window 22. Through the transparent window 22, the internal condition of the device can be seen to check the status of the cleaning fluid and whether it needs to be replaced.

[0038] refer to Figure 1 , Figure 2 The bottom of both sides of the outer casing 2 is bolted with brackets 23, which can stabilize the device.

[0039] Example 2:

[0040] refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 The constant temperature circulating cleaning device for ointment filling pipelines includes a water pump 11, which is embedded on the left side of the bottom of the inner shell 1. The water pump 11 has a flow rate of 10-30 L / min, a head of 5-10 m, and is made of 316L stainless steel. It ensures that the flow velocity in the pipeline is ≥1.5 m / s and the flushing force is ≥0.3 N / cm. 2 The top of the water pump 11 is connected to the outlet pipe 12, and the top of the outlet pipe 12 is connected to the left side of the bottom of the inner shell 1. The bottom of the water pump 11 is connected to the outlet pipe 13, and the left side of the top of the inner shell 1 is connected to the inlet pipe 14. The end of the outlet pipe 13 away from the water pump 11 is connected to the one-way valve 15. The valve plug opening pressure is 0.1-0.2MPa, and the closing reset time is ≤0.5s. The top of the one-way valve 15 is connected to the filling pipe 16. When the filling pipe 16 needs to be cleaned, the water pump 11 works to draw the constant temperature cleaning liquid from the lower layer through the outlet pipe 12 to the outlet pipe 13. The liquid enters the one-way valve 15 from the outlet pipe 13 and then enters the filling pipe 16 for cleaning. After cleaning the filling pipe 16, the cleaning liquid enters the inlet pipe 14 through the drainage system of the filling mechanism and finally returns to the upper layer inside the inner shell 1 for heating and circulation cleaning.

[0041] refer to Figure 1 , Figure 2 , Figure 5 The front and rear ends of the inner wall of the one-way valve 15 are hinged with valve plugs 19. By setting valve plugs 19, when cleaning is required, the cleaning pump 11 draws out the cleaning pump to open the valve plugs 19 and clean the filling pipeline 16. When not cleaning, the valve plugs 19 fall naturally to seal the bottom of the one-way valve 15 to prevent backflow.

[0042] Brief description of the usage process: The inner shell 1 contains cleaning fluid, which is divided into an upper and lower layer by a partition plate 3. The upper layer is a heating layer, and the lower layer is an insulation layer. When cleaning the filling pipe 16, the cleaning fluid that has been used to clean the filling pipe 16 enters the upper layer, is heated by the heating pipe 9, and then enters the through groove 4. From the through groove 4, it enters the lower layer and is kept warm by the insulation pipe 10, preparing for circulating cleaning. After the cleaning fluid enters the lower layer, the float 7 floats upward due to the cleaning fluid in the lower layer. The sliding rod 6 and the sliding groove 5 limit the movement of the float 7. After the cleaning fluid in the lower layer reaches a certain level, the float 7 drives the float plug 8 to block the bottom of the through groove 4, so that the upper and lower layers are disconnected. The cleaning fluid in the lower layer is then drawn out to clean the filling pipe. 16. At this time, the lower layer cleaning fluid decreases, the float 7 moves down and drives the float plug 8 to move, the upper layer and lower layer are connected and the cleaning fluid is supplied to the lower layer. The cleaning fluid returning to the upper layer is heated by the heating pipe 9 and then enters the lower layer and is kept warm by the heat preservation pipe 10 before cleaning. The cleaning fluid is kept at a constant temperature. When the filling pipe 16 needs to be cleaned, the water pump 11 works to draw the constant temperature cleaning fluid from the lower layer through the outlet pipe 12 to the outlet pipe 13. The fluid enters the one-way valve 15 from the outlet pipe 13 and then enters the filling pipe 16 for cleaning. The cleaning fluid after cleaning the filling pipe 16 enters the inlet pipe 14 through the drainage system of the filling mechanism and finally returns to the upper layer inside the inner shell 1 for heating and circulation cleaning.
