Description

Technical Field

[0001] The present invention relates to the technical field of water purification, and specifically to a filtering device for improving water quality by using water-soluble silicon Background Art

[0002] Water-soluble silicon is a silicon element that can dissolve in water. In the natural environment, silicon mainly exists in the form of silicon dioxide. Silicon is a trace element in the human body, and an appropriate intake of silicon is beneficial to human health, especially for the health of bones and connective tissues. Therefore, the trace element silicon required by the body can be supplemented by drinking purified water containing water-soluble silicon. Although silicon dioxide itself is insoluble in water, a method for obtaining silicon in drinking water can be provided by using soluble silicon compounds such as sodium silicate. For example, a sodium silicate carbon rod composite filter element is used to replace the traditional activated carbon filter element. Sodium silicate (water-soluble silicate) will undergo a hydrolysis reaction when it encounters water, generating silicic acid and sodium hydroxide. The generated silicic acid can adsorb impurities in the water and improve the water quality. At the same time, the silicon element can exist in the water in the form of silicic acid, providing beneficial minerals for the water body. The above method can be used for domestic water, industrial water or water production

[0003] As the use time of the sodium silicate carbon rod composite filter element increases, sodium silicate may be lost. In industrial water or water production, in order to meet a certain water quality standard, it is necessary to maintain a specific concentration of silicic acid in the water. Therefore, it may be necessary to monitor the content of silicic acid in the water after filtration and adjust the content of silicic acid in the water after filtration by supplementing the sodium silicate balance liquid. As the filter element is used, the amount of sodium silicate balance liquid to be supplemented gradually increases, but the position and number of the liquid outlet holes for inputting the sodium silicate balance liquid remain unchanged all the time. When the flow rate of the sodium silicate balance liquid is large, it is easy to reduce the uniform distribution of the sodium silicate balance liquid and increase the pressure of a single liquid outlet hole. When the flow rate of the sodium silicate balance liquid is small, the sodium silicate balance liquid may be in a lower flow rate condition, and then the mixing effect of the sodium silicate balance liquid and the water after filtration may be affected. In addition, after the sodium silicate balance liquid is input, only relying on the fluidity of the liquid for mixing, the achieved mixing effect still needs to be improved, and the time required to reach the expected fully mixed state is relatively long Summary of the Invention

[0004] The purpose of the present invention is to solve the technical problems that when the amount of sodium silicate balance liquid is input according to the increase in the use time of the sodium silicate carbon rod composite filter element, the number of liquid outlet holes cannot adapt to the change in the flow rate of the sodium silicate balance liquid, and the mixing effect achieved only by relying on the fluidity of the liquid is not good

[0005] To solve the above problems, the present invention provides a filtering device for improving water quality by using water-soluble silicon, which includes a filter with a sodium silicate carbon rod composite filter element, a medicine feeding mechanism arranged on the upper side of the branch section of a tee pipe, and a mixer connecting the medicine feeding mechanism and the corresponding branch section of the tee pipe. The water outlet end of the filter is connected to a tee pipe.

[0006] The medicine feeding mechanism includes a circular nozzle provided with a plurality of medicine adding holes, and an intermediate pipe connected to the circular nozzle and internally provided with a plugging member. The plugging member corresponds to the medicine adding holes one by one, and the medicine adding holes are uniformly arranged along the circumferential and radial directions of the circular nozzle. The plugging member includes a plug block; a top plate that slides up and down is further arranged in the intermediate pipe, and a triangular plate and a pushing member corresponding to the innermost plug blocks one by one are arranged on the lower side of the top plate.

[0007] The mixer is used to mix the sodium silicate balance liquid and the water filtered by the filter. The mixer includes a vertical stirring member that rotates automatically under the impact of the water flow entering the tee pipe, a horizontal stirring member corresponding to the circular nozzle and performing horizontal stirring while the circular nozzle adds medicine, and a mixing driving member for driving the horizontal stirring member to perform stirring and mixing.

[0008] Preferably, the plugging member further includes through holes opened on the plug blocks. The number of through holes carried by several plug blocks corresponding to the same radial line decreases by one from the inside to the outside. The number of through holes opened on the plug blocks in the innermost circle is three and is distributed along the radial direction. Then, the plug blocks in the second circle from the inside to the outside have two through holes, and the plug blocks in the third circle have one through hole. Connecting pipes corresponding to the through holes one by one are installed at the upper ends of the plug blocks, and the connecting pipes are slidably connected to the top plate. The plug blocks are elastically and slidably installed at the upper end of the circular nozzle.

[0009] Preferably, the medicine feeding mechanism further includes a partition plate. The partition plate divides the interior of the intermediate pipe into a main flow cavity and an installation cavity. The circular nozzle is arranged at one end of the intermediate pipe corresponding to the installation cavity; a closing plate is fixedly installed at the upper ends of the connecting pipes corresponding to the same plug block together. The upper end of the closing plate abuts against the lower end face of the partition plate. Flow holes corresponding to the medicine adding holes one by one and communicating with the main flow cavity are opened on the partition plate.

[0010] Preferably, the pushing member is composed of a rod and a roller rotatably connected to the upper end of the rod and in abutting cooperation with the inclined surface of the triangular plate. The rod is fixedly connected between the corresponding plug block, and the lower end of the rod is slidably connected to the upper end of the circular nozzle. The triangular plate is fixedly connected to the lower end of the top plate.

[0011] Preferably, the vertical stirring member is composed of a central shaft with a vertically extending axis and stirring blades evenly installed circumferentially outside the central shaft. The central shaft is rotatably installed in the housing. One side of the housing is connected and communicated with the corresponding branch section of the three-way pipe, and the other side of the housing is connected and communicated with a water pipe. The horizontal stirring member is composed of a horizontal shaft with a left-right extending axis and blades evenly installed circumferentially outside the horizontal shaft; the horizontal shaft is rotatably installed between two brackets, and the mixing driving member is arranged on the brackets and controls the rotation of the horizontal shaft.

[0012] Preferably, the mixer further includes a distance control member; the distance control member includes a push rod with a vertical sliding freedom arranged between two front and rear opposite brackets. A push plate is hinged between the lower end of the push rod and the upper end of the corresponding bracket, and the push plate is in a hinged relationship with the corresponding bracket and the push rod.

[0013] Preferably, outer extension plates penetrating the middle pipe are symmetrically installed on the left and right sides of the top plate, and the outer extension plates are slidably connected to the middle pipe up and down; a linkage member is jointly arranged between the two outer extension plates and the two push rods; the linkage member is used to synchronously drive the outer extension plates and the push rods to move up and down. During the process of the plug moving radially to adjust the number of chemical addition holes, the front and rear groups of brackets move synchronously in opposite directions. The linkage member includes a moving plate jointly installed at the upper ends of the push rods. An avoidance hole for the middle pipe to pass through is opened in the middle of the moving plate, and the outer extension plate is connected to the upper end of the moving plate.

[0014] Preferably, the chemical feeding mechanism further includes a strengthening member, which is used to improve the connection strength between several plugs on the same radial line during the adjustment of the number of chemical addition holes. The strengthening member is composed of an insertion block and an insertion shell that achieve plug-in fit between adjacent plugs on the same radial line.

[0015] The beneficial effects of the present invention:

[0016] 1. The present invention adopts a method of relying only on a single driving source to control the movement of the corresponding blocking member to open an appropriate number of chemical addition holes to adapt to the change in the input flow rate of the sodium silicate balance liquid. When the flow rate is large, the number of chemical addition holes is increased to adapt to a higher flow rate demand, ensuring the uniform distribution of the sodium silicate balance liquid and reducing the pressure on a single chemical addition hole; when the flow rate is small, the number of chemical addition holes is reduced to maintain an appropriate flow rate and kinetic energy, ensuring effective mixing even under low flow rate conditions.

[0017] 2. The present invention adopts a comprehensive mixing method that combines external mechanical agitation mixing with mixing relying on the fluidity of the liquid. During the input of the sodium silicate balance liquid, the sodium silicate balance liquid and the filtered water are mixed autonomously according to their own flow characteristics. At the same time, multi-directional and multi-region agitation mixing is implemented through the cooperation of the vertical stirring member and the horizontal stirring member, ensuring the uniform distribution of the sodium silicate balance liquid, accelerating the mixing of the sodium silicate balance liquid and the filtered water, and shortening the time required to achieve a fully mixed effect.

[0018] 3. Based on the ability to adjust the number of dosing holes according to the input flow rate of the sodium silicate balance liquid, improve the uniformity of the distribution of the sodium silicate balance liquid, reduce the pressure on a single dosing hole, and maintain the effect of basically effective autonomous flow mixing, the present invention combines mechanical agitation mixing to ensure the rapid, effective, and sufficient mixing of the sodium silicate balance liquid and the filtered water.

[0028] In order to make the above objects, features, and advantages of the present invention more obvious and understandable, the following will describe the specific embodiments of the present invention in detail with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0029] Please refer to Figure 1, a filtration device for improving water quality by using water-soluble silicon, the filtration device includes a filter 1 with a sodium silicate carbon rod composite filter element, and a tee is connected to the water outlet end of the filter 1.

[0030] It should be noted that the filtration device adopts a closed-frame design, and the sodium silicate carbon rod composite filter element is replaceable. The filter 1 is arranged in a housing. One side of the housing of this filtration device is provided with a water inlet, a liquid inlet, a bottled water outlet, a bagged water outlet, etc. A water inlet pipe is connected between the water inlet and the water inlet end of the filter 1. An electronic flow meter is arranged on the water inlet pipe to count the water production (the amount of water entering the filter 1) by using the electronic flow meter. The bottled water outlet and the bagged water outlet respectively correspond to the two branch sections of the tee. In addition, this filtration device should also have corresponding power sources (providing the energy required for the operation of the equipment), control systems (responsible for controlling the operation logic and process of the equipment), actuators (the part that executes specific tasks according to the instructions of the control system), transmission devices (used for energy transfer and conversion of motion forms), sensing and feedback systems (if the equipment needs to be adjusted according to the environment or its own state, the corresponding information is fed back to the control system), structural parts, auxiliary systems, interfaces and connections, display and operation interfaces, etc. The housing, water inlet, and other components involved in the above content are all prior arts and are not shown in the figure.

[0031] Please refer to Figure 1 and Figure 2 , this filtration device also includes a medicine feeding mechanism 2 arranged on the upper side of the branch section of the tee and a mixer 3 connecting the medicine feeding mechanism 2 and the corresponding branch section of the tee. The medicine feeding mechanism 2 includes a round nozzle 20 with a plurality of medicine adding holes. The medicine feeding mechanism 2 is used to adjust the number of medicine adding holes according to the flow rate of the sodium silicate balance liquid fed into the branch section of the tee; the mixer 3 is used to mix the sodium silicate balance liquid and the water filtered by the filter 1.

[0032] The whole filtering device is placed in a water-soluble silicon filtering system (not shown in the figure) for use. The water-soluble silicon filtering system also includes a sodium silicate balance solution in the stock solution tank, a storage tank, an automatic dosing pump, a metering pump, and a replenishing pump provided between the stock solution tank and the storage tank. The storage tank is connected to the medicine feeding mechanism 2 through a three-way infusion tube. The two medicine feeding mechanisms 2 correspond to the two branch segments of the three-way infusion tube one by one. Cooperating with the metering pump, the automatic dosing pump sucks a fixed amount of sodium silicate balance solution from the storage tank and adds it to the medicine feeding mechanism 2 through the three-way infusion tube, and then the medicine feeding mechanism 2 adds it to the corresponding three-way pipe branch segment. A TDS probe is arranged on the confluence section of the three-way pipe. The TDS probe on the confluence section of the three-way pipe is used to measure the total amount of dissolved solid substances in the water entering the confluence section of the three-way pipe from the water outlet end of the filter 1. The control panel of the filtering device will display the corresponding TDS value according to the measurement data of the TDS probe. If the TDS value is within the effective value range, the automatic dosing pump is not controlled to suck the sodium silicate balance solution from the storage tank for dosing. If the TDS value is outside the effective value range, the automatic dosing pump is controlled to suck the sodium silicate balance solution from the storage tank for dosing, and the dosing amount is adjusted accordingly according to the numerical difference between the TDS value and the minimum value in the effective value range. As the usage time of the filter 1 increases, its filtering effect will decline, so there will be no situation where the TDS value corresponding to the measurement of the TDS probe on the confluence section of the three-way pipe exceeds the maximum value of the effective value range. The bottled water outlet and the bagged water outlet are respectively connected to the mixer 3 through corresponding water pipes with a certain length. TDS probes are also arranged on the water pipes and control valves are also provided. The TDS probes are arranged close to the mixer 3, and the control valves are arranged away from the TDS probes. This TDS probe is used to measure the total amount of dissolved solid substances in the water after adding a certain amount of sodium silicate balance solution and effective mixing. If the TDS value is within the effective value range, there is no need to control the automatic dosing pump to suck the sodium silicate balance solution from the storage tank for dosing. If the TDS value is outside the effective value range, the automatic dosing pump is controlled to suck the sodium silicate balance solution from the storage tank and continue the dosing and mixing operations. The control system controls the opening and closing of the control valve according to the TDS value displayed by the measurement data of the TDS probe on the water pipe, and then controls whether the bottled water outlet and the bagged water outlet discharge water.

[0033] Please refer to Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 and Figure 6, the medicine feeding mechanism 2 further includes an intermediate pipe 21 connected to the circular nozzle 20 and internally provided with plugging members corresponding to the medicine adding holes one by one. The medicine adding holes are uniformly arranged along the circumferential and radial directions of the circular nozzle 20; a top plate 22 that slides up and down is further arranged in the intermediate pipe 21, and a triangular plate 23 and a pushing member corresponding to the innermost plugging members one by one are arranged on the lower side of the top plate 22; the pushing member is composed of a rod and a roller 24 rotatably connected to the upper end of the rod and in abutting and cooperating with the inclined surface of the triangular plate 23. The rod is fixedly connected to the corresponding block 25, and the lower end of the rod is slidably connected to the upper end of the circular nozzle 20. The triangular plate 23 is fixedly connected to the lower end of the top plate 22.

[0034] Please refer to Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 , the plugging member includes a block 25 elastically and slidably installed at the upper end of the circular nozzle 20 and having a through hole 26. Each block 25 in the innermost circle corresponds to two rods, and the rods are symmetrically distributed on both sides of the block 25. The triangular plate 23 corresponds to the roller 24 one by one. Radial grooves corresponding to the blocks 25 one by one and in sliding fit are formed on the circular nozzle 20, and the radial grooves are arranged to avoid the medicine adding holes. A return spring that abuts against the inner wall of the corresponding radial groove is connected to the side end of the block 25. The return spring is not shown in the figure. The number of through holes 26 carried by the blocks 25 corresponding to the same radial line decreases by one from the inside to the outside. Among them, the number of through holes 26 formed on the blocks 25 in the innermost circle is three and is distributed radially. Then, the blocks 25 in the second circle from the inside to the outside have two through holes 26, and the blocks 25 in the third circle have one through hole 26. A connecting pipe 250 corresponding to the through hole 26 one by one and used for connecting the through hole 26 and the medicine adding hole is fixedly connected to the upper end of the block 25. The connecting pipe 250 is slidably connected to the top plate 22. A partition plate 27 that divides the interior of the intermediate pipe 21 into a main flow chamber and an installation chamber is arranged in the intermediate pipe 21. The top plate 22 is arranged in the installation chamber, and the circular nozzle 20 is arranged at one end of the intermediate pipe 21 corresponding to the installation chamber. A closing plate is fixedly installed on the upper ends of the connecting pipes 250 corresponding to the same block 25 together. The upper end of the closing plate abuts against the lower end surface of the partition plate 27. Flow holes corresponding to the medicine adding holes one by one and communicating with the main flow chamber are formed on the partition plate 27.

[0035] During operation, the water to be filtered enters Filter 1 through the inlet pipe and undergoes filtration by the sodium silicate carbon rod composite filter element. The filtered water enters the tee at a constant flow rate from the outlet end of Filter 1. The total amount of dissolved solids in the water entering the confluence section of the tee from the outlet end of Filter 1 is measured by the TDS probe on the confluence section of the tee. According to the TDS value displayed on the control panel of the filtration device, it is determined whether to control the automatic dosing pump to suck the sodium silicate balance solution from the liquid storage tank for dosing. When it is necessary to control the automatic dosing pump to suck the sodium silicate balance solution from the liquid storage tank for dosing, the top plate 22 drives the triangular plate 23 to move downward. The inclined surface of the triangular plate 23 cooperates with the corresponding roller 24, causing the roller 24 to drive the rod to move radially along the circular nozzle 20. The innermost plug 25 moves radially synchronously with the corresponding rod. At the same time, the closing plate is driven through the connecting pipe 250. When the through hole 26 on the innermost plug 25, which is the farthest from the center of the circular nozzle 20, is directly opposite and connected to the innermost dosing hole on the circular nozzle 20, and the corresponding flow hole and the connecting pipe 250 are directly opposite and connected, the top plate 22 pauses its downward movement. At this time, the end of the innermost plug 25 abuts against the end of the second innermost plug 25 from the inside out, preparing for the subsequent pushing of the second innermost plug 25 by the innermost plug 25. Then, the automatic dosing pump sucks the sodium silicate balance solution from the liquid storage tank for dosing. The sodium silicate balance solution passes through the confluence section, branch section, and intermediate pipe 21 of the three-way infusion pipe in sequence, then enters the connecting pipe 250, and finally is sprayed into the mixer 3 through the connected through hole 26 and dosing hole. At the same time, the mixer 3 performs the operation of mixing the sodium silicate balance solution and the water filtered by Filter 1. It should be noted that the two dosing mechanisms 2 and the mixer 3 can work simultaneously or separately.

[0036] When the dosing amount increases and it is necessary to open the innermost dosing hole and the second innermost dosing hole simultaneously, the top plate 22 continues to move downward, enabling the inclined surface of the triangular plate 23 to further cooperate with the corresponding roller 24. The innermost plug 25 will push the second innermost plug 25 to move synchronously until the second innermost and innermost dosing holes are opened simultaneously, and the end of the second innermost plug 25 abuts against the end of the third innermost plug 25. According to the above process, when the dosing amount further increases, the innermost plug 25 continues to move, pushing the second innermost and third innermost plugs 25 to move together, and the three dosing holes are opened simultaneously. After the work is completed, the top plate 22 drives the triangular plate 23 to reset, and the plug 25 resets under the resilience of the reset spring. The rod resets synchronously with the corresponding plug 25.

[0037] Increasing the number of dosing holes at high flow rates is to meet higher flow requirements, ensure uniform distribution of the sodium silicate balance solution, and reduce the pressure on a single dosing hole; reducing the number of dosing holes at low flow rates is to maintain appropriate flow velocity and kinetic energy to ensure effective mixing even under low flow conditions.

[0038] Please refer to Figure 6 、 Figure 7 andFigure 8 The medicine feeding mechanism 2 further includes a reinforcing member for enhancing the connection strength between the blocking blocks 25 radially distributed along the circular nozzle 20 during the adjustment of the number of medicine adding holes. The reinforcing member is composed of an insertion block 28 and an insertion shell 29 that achieve the insertion fit between adjacent blocking blocks 25 on the same radial line. Specifically, the insertion blocks 28 are installed on the blocking blocks 25 other than the outermost ring of blocking blocks 25, and the insertion shells 29 are installed on the blocking blocks 25 other than the innermost ring of blocking blocks 25. The insertion block 28 is inserted into the corresponding insertion shell 29, and both the insertion block 28 and the insertion shell 29 are symmetrically distributed on the corresponding blocking blocks 25. The insertion end of the insertion block 28 is chamfered, and the insertion end of the insertion shell 29 is beveled. During the process that the through hole 26 farthest from the center of the circular nozzle 20 on the innermost ring of blocking blocks 25 is directly opposite and communicated with the innermost ring of medicine adding holes on the circular nozzle 20, and the corresponding flow holes and the connecting pipe 250 are directly opposite and communicated, the insertion block 28 on the innermost ring of blocking blocks 25 gradually inserts into the corresponding insertion shell 29. When the end of the innermost ring of blocking blocks 25 abuts against the end of the blocking blocks 25 in the second ring from the inside out, the end of the insertion block 28 abuts against the inner wall of the insertion shell 29 at the same time.

[0039] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4, the mixer 3 includes a vertical stirring member, a horizontal stirring member, and a mixing driving member. Under the impact of a fixed flow rate of water flowing into the tee, the vertical stirring member can rotate on its own. The horizontal stirring member corresponds to the circular nozzle 20. While the circular nozzle 20 sprays the sodium silicate balancing liquid downward for chemical addition, the horizontal stirring member is controlled by the mixing driving member to perform horizontal stirring. The vertical stirring member consists of a central shaft with a vertically extending axis and blades 30 evenly installed circumferentially outside the central shaft. The central shaft is rotatably installed in the housing 31. One side of the housing 31 is connected and communicated with the corresponding branch section of the tee. The other side of the housing 31 is respectively connected and communicated with the bottled water outlet and the bagged water outlet through corresponding water pipes. The number of central shafts is two and they are symmetrically arranged left and right with respect to the horizontal stirring member. The two central shafts are respectively located at the input end position and the output end position on both sides of the housing 31, so as to improve the effect of using water flow to make the vertical stirring member perform stirring and mixing. The horizontal stirring member consists of a horizontal shaft with a horizontally extending axis and blades 32 evenly installed circumferentially outside the horizontal shaft. The number of horizontal shafts is four and they are evenly divided into two groups. The two horizontal shafts in each group are jointly rotatably installed between the left and right brackets 33. The brackets 33 are movably connected to the inner bottom wall of the housing 31. The mixing driving member is arranged on the bracket 33 and controls the rotation of the horizontal shaft. The mixing driving member consists of a motor 34 and a pulley member. The two horizontal shafts in the same group are connected and driven through the pulley member. Among them, motors 34 are arranged at the upper ends of two front and rear opposite brackets 33. The output shafts of the motors 34 are also connected and driven to the adjacent horizontal shafts through the pulley member. The housing 31 consists of a main body and a detachably installed cover. The lower end of the central shaft is rotatably connected to the inner bottom wall of the main body, and the upper end is movably connected to the cover. The upper end of the motor 34 is slidably connected to the lower end of the cover through an adapter block.

[0040] The filtered water enters the tee from the water outlet end of the filter 1 in a state of a fixed flow rate, and then enters the corresponding housing 31 from the branch section of the tee. During this process, the water flow will impact the blades 30, causing the blades 30 and the central shaft to rotate. In this way, during chemical addition, the vertical stirring and mixing are carried out by using the blades 30, without driving to improve the mixing effect of the sodium silicate balancing liquid at the edge and the filtered water in the up and down directions and the left and right directions. At the same time, the motor 34 and the pulley member cooperate to make the horizontal shaft drive the blades 32 to rotate, and the rotating blades 32 are used to perform horizontal stirring, accelerating the mixing of the sodium silicate balancing liquid at the edge and the filtered water. Finally, the mixed water enters the water pipe and passes through the TDS probe arranged on the water pipe.

[0041] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4, the mixer 3 further includes a distance control member. The distance control member includes a push rod 35 that is arranged between two front and rear opposite brackets 33 and has a degree of freedom of vertical sliding. A push plate 36 is hinged between the lower end of the push rod 35 and the upper end of the corresponding bracket 33. The push plate 36 is in a hinged relationship with the corresponding bracket 33 and the push rod 35. The upper end of the push rod 35 slidably penetrates through the upper end of the cover. On the outer side of the top plate 22, extension plates 220 that penetrate through the intermediate pipe 21 are symmetrically installed on the left and right. The extension plates 220 are slidably connected to the intermediate pipe 21 up and down; A linkage member is jointly arranged between the two extension plates 220 and the two push rods 35. The linkage member includes a moving plate 37 commonly installed at the upper ends of the push rods 35. An avoidance hole for the intermediate pipe 21 to pass through is formed in the middle of the moving plate 37. The upper end of the moving plate 37 is fixedly connected to the pushing end of an electric push rod installed at the upper end of the cover. The extension plate 220 and the moving plate 37 are detachably connected.

[0042] When adjusting the number of dosing holes, the distance control member can drive the front and rear groups of brackets 33 to move synchronously and reversely to adjust the distance between the front and rear horizontal stirring members, so as to adapt to the spraying range of the sodium silicate balance liquid and improve the mixing effect of the horizontal stirring members on the sodium silicate balance liquid at the edge and the filtered water. Specifically: The electric push rod is controlled by the control system to move the moving plate 37 and the extension plate 220 downward. The extension plate 220 drives the top plate 22 and the triangular plate 23 to move downward synchronously. The triangular plate 23 and the pushing member cooperate to adjust the number of opened dosing holes. While the moving plate 37 moves downward, it also drives the push rod 35 to move downward. The hinge point between the push rod 35 and the push plate 36 moves downward, causing the opening angle of the front and rear push plates 36 to increase. The push plate 36 pushes the corresponding bracket 33 to move linearly. The bracket 33 drives the corresponding horizontal stirring member and the motor 34 to move together. During the process of successively controlling each ring of the sealing members to move radially inward and outward synchronously, the distance between the front and rear groups of brackets 33 gradually increases.

[0043] Please refer to Figure 2 , Figure 4 and Figure 5, to facilitate the inspection of the medicine feeding mechanism 2, the intermediate pipe 21 is set as an assembled structure. Specifically: the intermediate pipe 21 is composed of a section of pipe connected to the branch section of the three-way infusion pipe, a second section of pipe threadedly connected to the lower end of the first section of pipe, and a third section of pipe threadedly connected to the lower end of the second section of pipe. The partition plate 27 is inserted and connected to the upper end of the second section of pipe. The extension plate 220 penetrates through the third section of pipe. The upper end of the round nozzle 20 is inserted into the lower end inside the third section of pipe, and the lower end is located outside the third section of pipe and is fixed to the third section of pipe by bolts. The middle of the cover is provided with an installation through groove, and the third section of pipe is threadedly connected to the installation through groove. The presence of the electric push rod will not affect the connection between the medicine feeding mechanism 2 and the cover.
