Description

Technical Field

[0001] This utility model relates to the field of filtration technology, and in particular to a soilless filtration system. Background Technology

[0002] Filtration is a commonly used technology in fluid transportation. It removes impurities from fluids to purify them. For example, in the production of liquor, soilless filtration systems are required. These systems typically include a raw liquid tank, a filtration device, and a clear liquid tank. The raw liquid in the raw liquid tank is filtered by the filtration device and then enters the clear liquid tank.

[0003] However, in the liquor production industry, activated carbon powder is often added to the liquor. Activated carbon powder is a solid substance, so it will precipitate in the raw liquor tank, forming a lower solid layer and an upper supernatant layer. In the soilless filtration system known to the applicant for use in liquor production, in order to avoid removing the solid layer and clogging the filtration equipment, the supernatant layer in the raw liquor tank is directly extracted and supplied to the filtration equipment. That is, the location of the extraction of raw liquor in the raw liquor tank is not at the bottom of the inner cavity of the raw liquor tank. This results in the final raw liquor tank retaining a solid layer and some residual liquid. Currently, there are roughly two ways to deal with the solid layer and residual liquid. One is direct discharge, which wastes the residual liquid and pollutes the environment. The other is to remove the solid layer and residual liquid together and separate them using additional separation equipment. This method will significantly increase production costs.

[0004] Therefore, there is an urgent need for a soilless filtration system that can recover residual liquid and has a low production cost. Utility Model Content

[0005] The purpose of this invention is to provide a soilless filtration system to solve the problems existing in the prior art. It actively uses a stirring device to stir the raw liquid in the raw liquid storage device into a turbid liquid and then filters the turbid liquid. This can process all substances in the raw liquid storage device, avoid the generation of residual liquid, and at the same time, the production cost is low.

[0006] To achieve the above objectives, the present invention provides the following solution: The present invention provides a soilless filtration system, including a raw liquid storage device, a solid-liquid separation device, and a clear liquid storage device. The lowest end of the inner cavity of the raw liquid storage device is connected to the solid-liquid separation device via a delivery pump.

[0015] The present invention achieves the following main technical effects compared to the prior art: Actively eliminating stratification within the stock solution storage device through a stirring device allows solid impurities to disperse in the stock solution, forming a turbid liquid.

[0022] The purpose of this invention is to provide a soilless filtration system to solve the problems existing in the prior art. It actively uses a stirring device to stir the raw liquid in the raw liquid storage device into a turbid liquid and then filters the turbid liquid. This can process all substances in the raw liquid storage device, avoid the generation of residual liquid, and at the same time, the production cost is low.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Please refer to the following: Figure 1 As shown, a soilless filtration system is provided, including a raw liquid storage device, a solid-liquid separation device 5, and a clear liquid storage device 6. The lowest end of the inner cavity of the raw liquid storage device is connected to the solid-liquid separation device 5 via a transfer pump 3. The clear liquid outlet of the solid-liquid separation device 5 is connected to the clear liquid storage device 6. The raw liquid storage device is equipped with a stirring device 4 for stirring the raw liquid into a turbid raw liquid. The stirring device 4 actively eliminates the stratification phenomenon in the raw liquid storage device, so that solid impurities are dispersed in the raw liquid to form a turbid liquid. The turbid liquid is then filtered, which can achieve the filtration treatment of all substances in the raw liquid storage device. This can avoid the retention of a precipitated solid layer and residual liquid in the raw liquid storage device. At the same time, by adding only one stirring device 4, compared with removing the solid layer and residual liquid for further processing, the production cost can be effectively reduced.

[0025] The stirring device 4 can be a bubbling device or a rotating stirring wheel or other stirring equipment.

[0026] When using a bubbling device, multiple rows of pipes or a hollow disc are evenly arranged at the bottom of the inner cavity of the stock solution storage device. Multiple small holes are evenly opened on the pipes or disc. The pipes or disc are connected to the fluid supply device. The fluid is discharged into the stock solution storage device through the small holes on the pipes or disc to realize the bubbling and stirring function of the stock solution.

[0027] The fluid supply equipment can supply compressed gas or liquid.

[0028] When a pump for supplying liquid is selected as the fluid supply device, it can be used as the raw liquid transfer pump 3 of the raw liquid storage device. That is, the raw liquid is supplied into the raw liquid storage device by the pump. The supplied raw liquid can ensure the continuous operation of the system. Alternatively, the impact force discharged from the small hole can be used to agitate and stir the raw liquid in the raw liquid storage device.

[0029] In one embodiment, the clear liquid storage device 6 is connected to the original liquid storage device via a transfer pump 3 to supply the filtered clear liquid to the original liquid storage device, thereby cleaning the original liquid storage device. At the same time, the cleaning substance is the treated clear liquid, which will not cause pollution to the original liquid storage device.

[0030] A first sprayer 7 can be installed at the top of the inner cavity of the stock solution storage device. The first sprayer 7 is connected to the clear solution storage device 6 through a delivery pump 3. The spraying function of the sprayer can be used to improve the cleaning effect of the stock solution storage device. The first sprayer 7 is connected to external clean water through the delivery pump 3. At this time, the spraying function of the sprayer can be used to dilute the stock solution inside while cleaning the stock solution storage device. In actual use, the clear solution supply passage and the clean water supply passage of the first sprayer 7 can be controlled to select clear solution spraying or clean water spraying. Of course, an additional passage can also be designed on the stock solution storage device to introduce clean water to achieve the dilution effect.

[0031] In one embodiment, the raw liquid storage device includes a raw liquid tank 1, which has a raw liquid inlet. The bottom of the raw liquid tank 1 is arc-shaped, conical, or inclined. The lowest end of the inner cavity of the raw liquid tank 1 is connected to a solid-liquid separation device 5 via a delivery pump 3, so that the raw liquid can be completely delivered to the solid-liquid separation device 5. A stirring device 4 is provided inside the raw liquid tank 1, and a first sprayer 7 is installed at the top of the inner cavity of the raw liquid tank 1.

[0032] In one embodiment, the raw liquid storage device further includes a temporary storage tank 2. The raw liquid tank 1 is connected to the temporary storage tank 2 via a transfer pump 3. The temporary storage tank 2 is connected to the solid-liquid separation device 5 via a transfer pump 3. The temporary storage tank 2 can temporarily store the raw liquid.

[0033] An additional concentration filter 15 can be designed. When the whole system is not in use and a portion of the original liquid remains in the temporary storage tank 2, the concentration filter 15 can be used to process the original liquid. The processed clear liquid is then transported to the clear liquid storage device 6. The concentration filter 15 can also be used during the maintenance of the solid-liquid separation device 5.

[0034] The bottom of the temporary storage tank 2 is set in an arc shape, a cone shape or an inclined surface, and the lowest end of the inner cavity of the temporary storage tank 2 is connected to the solid-liquid separation device 5, which can realize the emptying of the original liquid in the temporary storage tank 2.

[0035] The original liquid tank 1 is connected to the bottom of the inner cavity of the temporary storage tank 2 through a pipeline to achieve a certain stirring function and prevent sedimentation from forming in the temporary storage tank 2.

[0036] A second sprayer 8 is installed at the top of the inner cavity of the temporary storage tank 2. The second sprayer 8 is connected to the clear liquid storage device 6 through the transfer pump 3, and uses the filtered clear liquid to clean the temporary storage tank 2.

[0037] In one embodiment, the solid-liquid separation device 5 includes a cylinder and a filter element. The filter element is disposed inside the cylinder, and the cylinder is connected to the raw liquid storage device. The filter element is connected to the clear liquid storage device 6 through the clear liquid conveying pipeline 13. The filter element filters the raw liquid. A solid discharge port is provided at the bottom of the cylinder for discharging impurities.

[0038] In one embodiment, a compressed gas delivery pipeline 9 is also provided. The compressed gas delivery pipeline 9 is connected to the inner cavity of the cylinder through a first branch 10. A residual pressure return pipeline 12 is provided at the bottom of the cylinder. The residual pressure return pipeline 12 is connected to the raw liquid storage device. Valves are provided on the pipeline connecting the cylinder to the raw liquid storage device, the clear liquid delivery pipeline 13, the first branch 10, and the residual pressure return pipeline 12. Before the filter element needs to be regenerated, the pipeline connecting the cylinder to the raw liquid storage device and the clear liquid delivery pipeline 13 are closed, and the first branch 10 and the residual pressure return pipeline 12 are opened. Gas enters the cylinder and returns the residual pressure in the cylinder to the raw liquid storage device. After the residual pressure is returned, the regeneration of the filter element can be started. During the regeneration process, the impurities that are removed from the filter element are discharged from the solid discharge port. Since there is no raw liquid in the cylinder at this time, the waste of raw liquid is avoided during the filter element regeneration process.

[0039] When the residual hydraulic pressure return line 12 is installed, the residual hydraulic pressure return line 12 can be connected to the temporary storage tank 2, and the connecting line extends to the bottom of the inner cavity of the temporary storage tank 2.

[0040] The compressed gas delivery pipeline 9 is connected to the inner cavity of the filter element through the second branch 11. The second branch 11 is equipped with a valve. By closing the pipeline connecting the cylinder to the raw liquid storage device, the clear liquid delivery pipeline 13, the first branch 10, and the residual liquid return pipeline 12, and opening the second branch 11, the gas is used to backflush the filter element and blow off the impurities on the filter element.

[0041] An exhaust pipe can be installed on the cylinder. When the first branch 10 and the exhaust pipe are opened simultaneously, the airflow passes over the surface of the filter element to blow away impurities and facilitate subsequent treatment of the impurities.

[0042] A clear liquid direct outlet pipeline 14 can be set up in parallel with the clear liquid delivery pipeline 13 to realize the direct discharge of clear liquid.

[0043] Valves are installed at both ends of the delivery pump 3 so that the intermediate delivery pump 3 can be easily replaced or maintained by closing the valves on both sides.

[0044] In actual use, before starting the filter, the stirring device 4 is started. The stirring device 4 stirs the original liquid in the original liquid storage device into a turbid liquid to ensure that the solid substances in the original liquid are dispersed evenly. Then the filter is started. The turbid liquid is transported by the transfer pump 3 to the solid-liquid separation device 5 for solid-liquid separation. Solid impurities are intercepted by the filter element, and the clear liquid is transported to the clear liquid storage device 6.

[0045] After filtration is completed and before shutdown, the clear liquid in the clear liquid storage device 6 can be transferred to the original liquid tank 1 by the transfer pump 3 to clean the original liquid tank 1. At the same time, the original liquid in the original liquid tank 1 is continuously transferred until the cleaning is completed and there is no residual liquid in the original liquid tank 1. Then the machine is stopped. The original liquid in the temporary storage tank 2 can be used for the next time, or it can be discharged through the discharge port and properly stored for the next time. Alternatively, the residual liquid in the temporary storage tank 2 can be treated by the concentration filter 15 so that no residual liquid remains in the temporary storage tank 2. In the end, there is no residual liquid in the original liquid tank 1 and the temporary storage tank 2, and the residual liquid is recycled and treated.

[0046] Any adaptive changes made according to actual needs are within the protection scope of this utility model.
