Description

Technical Field

[0001] The utility model relates to the technical field of surfactant filtration, in particular to a fine filtering device for preparing surfactants. Background Art

[0002] At present, surfactants, also known as interfacial agents, are compounds that can significantly reduce the surface tension or interfacial tension between two liquids, between liquid and gas, and between liquid and solid. The molecular structure of surfactants is amphiphilic: one end is a hydrophilic group and the other end is a hydrophobic group. Surfactants are divided into ionic surfactants, non-ionic surfactants, compound surfactants, and other surfactants.

[0003] Among them, in some polymer aqueous solutions, surfactants can chemically react with the macromolecules therein to form polymer accumulation and cross-linking, thereby forming a certain three-dimensional spatial structure and increasing viscosity.

[0004] However, it is more difficult to filter viscous liquid surfactants. When using a fine filter element, it is difficult for the viscous liquid surfactant to pass through the filter element by its own gravity, and the filtration efficiency is extremely low. Therefore, a new technical solution needs to be designed to solve this problem. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fine filtering device for preparing a surfactant, comprising a raw material box, a material pump is connected and installed on one side of the bottom of the raw material box, a material guide pipe is connected and installed on the outlet port of the material pump, a tank body is connected and installed on the other end of the material guide pipe, a filter pipe is connected and installed on the top of the tank body, and a pressurizing mechanism is installed inside the tank body;

[0007] The boosting mechanism includes limit rods fixedly installed on both sides of the tank body, sealing plates slidably installed on two groups of the limit rods, rubber rings fixedly installed on the outer walls of the sealing plates, extrusion blocks fixedly installed on the bottom of the sealing plates, a boosting pump fixedly installed on the top of the tank body, and an ultrasonic sensor fixedly installed on the top of the tank body.

[0008] As an optional solution of the technical solution of the present application, the booster pump outlet port is connected to the inside of the tank body, and the sealing plate is movably connected to the inner cavity of the tank body, so as to squeeze the surfactant inside the tank body.

[0009] As an optional solution of the technical solution of the present application, a slot is provided on one side of the filter tube, and a quick-release mechanism is installed in the slot.

[0010] As an optional solution of the technical solution of the present application, the quick-release mechanism includes a filter box movably inserted in the slot, a filter element detachably installed inside the filter box, and a limit frame fixedly installed on both sides of the filter tube, so that the filter box is easy to install and disassemble.

[0012] As an optional solution of the technical solution of the present application, a pressure relief pipe is installed on the top of the side wall of the tank body, a pressure sensor is installed on one end of the top of the tank body, and solenoid valves are installed at the bottom of the pressure relief pipe, the material guide pipe and the filter tube, which can detect the internal pressure value of the tube body at any time.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The technical solution of the present application can continuously deliver air pressure to the top side of the tank body by driving the booster pump in the booster mechanism, and continuously squeeze the sealing plate located at the top of the tank body toward the bottom. The sealing plate drives the extrusion block to squeeze the surfactant inside the tank body, which can accelerate the efficiency of the surfactant passing through the filter box, thereby improving the surfactant filtration efficiency and avoiding spending a lot of time waiting for the surfactant to pass through the filter box by its own gravity.

[0015] 2. The technical solution of the present application is to open a slot on one side of the filter tube, and a quick-release mechanism is installed in the slot. When the filter box inside the filter tube is used for a long time, the bolts on the outside of the sealing box can be screwed together to quickly remove the sealing box from the slot, and the filter element in the filter box can be replaced and cleaned in time, and then installed in the slot again, to ensure that the filter mechanism of the device can be quickly replaced and cleaned, to avoid long-term disassembly and replacement of the filter mechanism and delay in the filtration efficiency of the surfactant.

[0021] The boosting mechanism includes limit rods fixedly installed on both sides of the tank body 13, a sealing plate 2 slidably installed on the two sets of limit rods, a rubber ring 21 fixedly installed on the outer wall of the sealing plate 2, an extrusion block 22 fixedly installed on the bottom of the sealing plate 2, and a boosting pump 23 fixedly installed on the top of the tank body 13. The outlet port of the boosting pump 23 is connected to the inside of the tank body 13, and the sealing plate 2 is movably connected to the inner cavity of the tank body 13, so as to extrude the surfactant inside the tank body 13.

[0022] In this technical solution, by driving the boost pump 23 in the boost mechanism, air pressure can be continuously delivered to the top side of the tank body 13, and the sealing plate 2 located on the top of the tank body 13 can be continuously squeezed toward the bottom. The sealing plate drives the extrusion block 22 to squeeze the active agent inside the tank body 13, which can accelerate the efficiency of the surfactant passing through the filter box 31, thereby improving the surfactant filtration efficiency and avoiding spending a lot of time waiting for the active agent to pass through the filter box 31 by its own gravity.

[0023] In some technical solutions, a slot 3 is provided on one side of the filter tube 14, and a quick-release mechanism is installed in the slot 3. The quick-release mechanism includes a filter box 31 movably inserted in the slot 3, a filter element 32 detachably installed inside the filter box 31, and limit frames 33 fixedly installed on both sides of the filter tube 14, so that the filter box 31 is easy to install and disassemble. The two groups of limit frames 33 are respectively fitted with the two sides of the filter box 31. The outer wall of the filter box 31 is threadedly installed with the side wall of the filter tube 14 by bolts, which can support and limit the inner wall of the filter box 31.

[0024] In this technical solution, when the filter box 31 inside the filter tube 14 is used for a long time, the bolts on the outside of the sealing box can be screwed together to quickly remove the sealing box from the slot 3, and the filter element 32 in the filter box 31 can be replaced and cleaned in time and installed in the slot 3 again, to ensure that the filter mechanism of the device can be quickly replaced and cleaned, to avoid long-term disassembly and replacement of the filter mechanism and delay in the filtration efficiency of the surfactant.

[0025] In some technical solutions, an ultrasonic sensor 24 is fixedly installed on the top of the tank body 13, and a pressure relief pipe 4 is installed in communication with the top of the side wall of the tank body 13.

[0026] In this technical solution, when the boosting mechanism continuously squeezes the sealing plate 2, the ultrasonic sensor 24 can constantly detect the displacement distance of the sealing plate 2. When the displacement distance of the sealing plate 2 reaches the set value, a signal will be transmitted to the control processor, and the solenoid valves on the pressure relief pipe 4 and the material guide pipe 12 will be opened, so that the surfactant inside the raw material box 1 can be reintroduced into the tank body 13, and the surfactant can be repeatedly filtered.

[0028] In this technical solution, when the booster pump 23 continuously delivers pressure to the interior of the tank body 13, the pressure sensor 41 can be used to detect the internal pressure value of the tank body 13 at all times. When the internal pressure of the tank body 13 reaches the set value of the pressure sensor 41, the booster pump 23 will be turned off and the pressurization of the tank body 13 will stop. Conversely, when the internal pressure value of the tank body 13 is lower than the set value of the pressure sensor 41, the booster pump 23 will be continuously driven to deliver pressure to the interior of the tank body 13.

[0030] When in use, first, by driving the extraction pump 11, the active agent in the raw material box 1 is quantitatively introduced into the tank body 13, and the solenoid valve on the guide pipe 12 is closed. In conjunction with the filter box 31 installed in the filter tube 14, the active agent in the tank body 13 can be filtered, and at the same time, the booster pump 23 in the booster mechanism can be driven to continuously deliver air pressure to the top side of the tank body 13, and the sealing plate 2 located on the top of the tank body 13 is continuously squeezed toward the bottom. The sealing plate drives the extrusion block 22 to squeeze the active agent in the tank body 13, which can accelerate the efficiency of the surfactant passing through the filter box 31, thereby improving the surfactant filtration efficiency and avoiding spending a lot of time waiting for the active agent to pass through the filter box 31 by its own gravity. When the ultrasonic sensor 24 detects When the displacement distance of the sealing plate 2 reaches the set value, a signal will be transmitted to the control processor, and the solenoid valves on the pressure relief pipe 4 and the material guide pipe 12 will be opened, so that the surfactant inside the raw material box 1 can be re-introduced into the tank body 13, and the surfactant is repeatedly filtered. At the same time, a slot 3 is opened on one side of the filter tube 14, and a quick-release mechanism is installed in the slot 3. When the filter box 31 inside the filter tube 14 is used for a long time, the bolts on the outer side of the sealing box can be screwed together to quickly remove the sealing box from the slot 3, and the filter element 32 in the filter box 31 can be replaced and cleaned in time, and then installed in the slot 3 again, to ensure that the filter mechanism of the device can be quickly replaced and cleaned, to avoid long-term disassembly and replacement of the filter mechanism and delay of the surfactant filtration efficiency.
