Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of purification and stirring equipment, specifically relating to a gas circulation system for pressure filtration and aeration of a natural plant anti-hair loss scalp essence. Background Technology
[0002] The main ingredient of this natural plant-based anti-hair loss scalp serum is an extract of various Chinese herbal medicines, which improves the scalp's microenvironment and strengthens hair roots. In addition, the serum also contains some auxiliary ingredients. The manufacturing process involves not only extracting various herbal essences but also mixing them with the auxiliary ingredients.
[0003] In the environmental protection field, especially in wastewater treatment, technicians often use aeration in mixing tanks (aeration tanks) to improve mixing efficiency. The air entering the tank is then exhausted through an exhaust pipe or directly dispersed. However, when this aeration method is introduced into mixing tanks in the daily chemical industry, especially those containing traditional Chinese medicine extracts, high-purity inert gases (nitrogen, carbon dioxide, argon, or other gases) are used as the aeration source to prevent air from contaminating the extracts or causing oxidation. Therefore, directly venting the aerated inert gas would make it a consumable, increasing production costs. Furthermore, to prevent the inert gas from altering the air composition of the production area, additional ventilation ducts are required, further increasing production costs. Utility Model Content
[0004] This invention provides a gas circulation system for pressure filtration and aeration of natural plant anti-hair loss scalp essence, which solves the technical problem in the prior art where the aeration gas escapes after aeration of the mixing tank and cannot be reused, resulting in increased costs.
[0005] This utility model includes: at least one mixing tank;
[0006] Several extraction tanks are arranged around the stirred tank;
[0007] The first air passage has one end connected to the stirring tank, and the other end of the first air passage has several first air passage branches, which are respectively connected to several extraction tanks.
[0008] The second air passage has several second air passage branches at one end, which are respectively connected to several extraction tanks, and the other end of the second air passage is connected to the stirring tank.
[0009] Several gas storage tanks are respectively installed on several branches of the second gas duct;
[0010] The bypass tube connects to the second airway.
[0011] This invention first injects an aeration gas source into the mixing tank to aerate it and improve the mixing effect. Then, the gas in the mixing tank is injected into the extraction tank through the first air channel. The first air pump increases the pressure of the gas injected into the extraction tank, raising the internal pressure of the extraction tank and helping to increase the flow rate of the extract in the extraction tank. Then, the excess gas is returned to the mixing tank through the second air channel for aeration. This cycle continues, and the gas does not directly escape. It can not only be reused but also helps the extraction tank to perform pressure filtration, improving the extraction efficiency.
[0012] Furthermore: a first air pump is provided on the first airway branch, and a first pressure regulating valve assembly is also provided on the first airway branch, the first pressure regulating valve assembly being located on the outlet side of the first air pump;
[0013] A second air pump is provided on the second air duct branch. The second air pump is located between the extraction tank and the gas storage tank. Both the inlet and outlet ends of the gas storage tank are equipped with shut-off valves.
[0014] The second gas duct is equipped with a second pressure regulating valve assembly. The advantages of this step are: the gas pressure in the stirring tank and extraction tank can be controlled by the first and second pressure regulating valve assemblies; in addition, the gas storage tank can serve as a temporary transfer point for excess gas in the circulation pipeline, improving the safety of the circulation pipeline; with the shut-off valve on the gas storage tank, the gas inside can be stored in the gas storage tank when the stirring tank and / or extraction tank are changed, avoiding gas waste.
[0015] Furthermore, both the stirring tank and the extraction tank are equipped with one-way breather valves at their tops. The beneficial effect of this step is that if the pressure inside the stirring tank and the extraction tank becomes too high, the pressure can be reduced by venting air outward through the one-way breather valves, thus providing a safety and explosion-proof function.
[0016] Furthermore: the extraction vessel includes an inner ring and an outer ring, and the end of the second gas channel branch is located between the inner ring and the outer ring. The beneficial effect of this step is that the inner ring is used to isolate the extractant, thereby achieving gas-liquid separation.
[0017] Furthermore: a primary manifold, a secondary manifold, and an n-stage manifold are provided between the second air passage and the mixing tank, where n≥3;
[0018] The primary manifold is connected to the second airway via a first branch;
[0019] The secondary manifold is connected to the primary manifold via a second branch;
[0020] The n-th stage manifold is connected to the (n-1)-th stage manifold through the nth branch. The beneficial effect of this step is that the aeration effect is more uniform through the setting of multi-stage manifolds.
[0021] Furthermore: the end of the nth manifold is provided with a one-way nozzle, which is connected to the bottom of the mixing tank. The beneficial effect of this step is that the one-way nozzle can prevent the mixed liquid in the mixing tank from entering the second gas passage when the gas pressure is low.
[0022] The beneficial effects of this utility model are:
[0023] By aerating the mixing tank to improve the mixing effect, and by injecting gas into the extraction tank to increase the extraction effect, the gases in different tanks are connected into a closed-loop system through circulation pipelines, which can achieve efficient utilization of gas and reduce production costs.

[0032] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.
[0033] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.
[0034] Implementation of this application, for example Figures 1-3 As shown, the gas circulation system for pressure filtration and aeration of natural plant anti-hair loss scalp essence provided by this utility model allows gas to be input into the extraction tank after aeration, pressurizing the extraction tank to improve extraction efficiency, and then reinjected into the stirring tank for aeration, realizing closed-loop gas recycling and achieving the purpose of saving costs.
[0035] This utility model includes: at least one mixing tank 1;
[0036] Several extraction tanks 2 are arranged around the stirred tank 1, so as to... Figure 1 For example, here is a piping layout diagram when there are at least two extraction tanks 2;
[0037] The first air passage 3 has one end connected to the stirring tank 1, and the other end of the first air passage 3 is provided with a plurality of first air passage branches 31, which are respectively connected to a plurality of extraction tanks 2.
[0038] The second air passage 4 has a plurality of second air passage branches 41 at one end, which are respectively connected to a plurality of extraction tanks 2. The other end of the second air passage 4 is connected to the stirring tank 1. The stirring tank and a plurality of extraction tanks are connected through the first air passage 3, the first air passage branch 31, the second air passage 4 and the second air passage branch 41 to form a closed air passage.
[0039] Several gas storage tanks 5 are respectively installed on several second gas channel branches 41. Excess gas in the stirring tank 1, extraction tank 2 and each gas channel can be stored in the gas storage tanks 5.
[0040] The bypass pipe 6 is connected to the second air passage 4. When the total gas volume of the entire closed-loop air passage is insufficient, the bypass pipe 6 can be connected to a gas source for convenient gas replenishment.
[0041] This invention first injects an aeration gas source into the mixing tank 1 to aerate the mixing tank 1 and improve the mixing effect. Then, the gas in the mixing tank 1 is injected into the extraction tank 2 through the first air channel 3. The first air pump 32 increases the pressure of the gas injected into the extraction tank 2, thereby increasing the internal pressure of the extraction tank 2 and helping to increase the flow rate of the extract in the extraction tank 2. Then, the excess gas is returned to the mixing tank 1 through the second air channel 4 for aeration. This cycle continues, and the gas does not directly escape. It can not only be recycled, but also help the extraction tank to perform pressure filtration and improve the extraction efficiency.
[0042] Based on the above technical solution, a first air pump 32 is provided on the first air passage branch 31, and a first pressure regulating valve assembly 33 is also provided on the first air passage branch 31. The first pressure regulating valve assembly 33 is located on the outlet side of the first air pump 32.
[0043] A second air pump 42 is provided on the second air channel branch 41. The second air pump 42 is located between the extraction tank 2 and the gas storage tank 5. Both the inlet and outlet ends of the gas storage tank 5 are provided with shut-off valves 43.
[0044] The second gas passage 4 is equipped with a second pressure regulating valve assembly 7; both the first pressure regulating valve assembly 33 and the second pressure regulating valve assembly 7 include a pressure regulating valve body, an actuator, and a sensor. The sensor is correspondingly located inside the stirring tank 1 and the extraction tank 2. The sensor detects the internal pressure of the tank. When the internal pressure reaches the set value, the sensor can send a passive signal to the actuator, which will adjust the opening of the pressure regulating valve body to adjust the internal pressure of the tank. The first pressure regulating valve assembly 33 and the second pressure regulating valve assembly 7 control the gas pressure in the stirring tank 1 and the extraction tank 2 to keep it within the normal pressure range. In addition, the gas storage tank 5 can serve as a temporary transfer point for excess gas in the circulation pipeline, improving the safety of the circulation pipeline. With the shut-off valve on the gas storage tank 5, the gas inside the stirring tank 1 and / or the extraction tank 2 can be stored in the gas storage tank 5 when changing materials, avoiding gas waste.
[0045] Based on the above technical solution, both the top of the stirring tank 1 and the extraction tank 2 are equipped with a one-way breather valve 8. If the pressure inside the stirring tank 1 and the extraction tank 2 is too high, the one-way breather valve 8 can be used to vent air outward, reduce the internal pressure, and play a role in safety and explosion prevention.
[0046] Based on the above technical solution, the extraction tank 2 includes an inner ring 21 and an outer ring 22. Generally, the height of the inner ring 21 is higher than the liquid level in the extraction tank 2. The gap between the inner ring 21 and the outer ring 22 is connected to the interior of the extraction tank 2 above, while the gap below is closed to prevent the extractant from flowing into the gap. The end of the second gas channel branch 41 is located between the inner ring 21 and the outer ring 22. The inner ring 21 and the outer ring 22 are used to isolate the extractant and play a role in gas-liquid separation. In addition, the inner ring 21 and the outer ring 22 are generally provided with reinforcing ribs, guide plates and other structures in this shell-and-tube structure.
[0047] Based on the above technical solution, a primary manifold 401, a secondary manifold 402 to an nth manifold are provided between the second air passage 4 and the mixing tank 1, where n≥3;
[0048] The primary manifold 401 is connected to the second airway 4 via the first branch 403;
[0049] The secondary manifold 402 is connected to the primary manifold 401 via the second branch 404;
[0050] The n-stage manifold is connected to the (n-1)-stage manifold via the nth brancher. The branched structure of the multi-stage manifold allows for a more even distribution of the air injection ports at the bottom of the mixing tank 1, resulting in better aeration. It should be noted that... Figure 3 This is for illustrative purposes only and does not represent the actual number of manifolds at each level.
[0051] Based on the above technical solution, the end of the nth manifold is provided with a one-way nozzle, which is connected to the bottom of the mixing tank 1. The one-way nozzle can prevent the mixed liquid in the mixing tank 1 from entering the second gas passage 4 when the gas pressure is low.
[0052] In the above embodiments, filters may also be provided on the first air passage 3 and the second air passage branch 41 of this application to filter and absorb the extract or mixture carried out by the exhaust gas, so as to avoid mutual contamination.
