Description

Technical Field

[0001] The invention belongs to the technical field of fertilizer processing, relates to a liquid fertilizer processing device, and particularly relates to a turbulent flow absorption, vibration and agitation device for earthworm castings matrix solution. Background Art

[0002] The prior art "Agitation Device for Producing Liquid Fertilizer Matrix Solutions Based on Vermicompost" (ZL 201320007350.1) discloses an agitation device for fully dissolving and separating soluble nutrients in vermicompost for use as a liquid fertilizer matrix solution, and the "Production Method for Liquid Fertilizer Matrix Solutions Based on Vermicompost" (ZL20131 0005307.6) discloses mixing vermicompost with water in an appropriate weight ratio to obtain an earthworm extract mixture, which is then introduced into an agitation tank. Oxygen is introduced from the bottom of the agitation tank to agitate the earthworm extract mixture for several hours, thereby fully dissolving various nutrients in the vermicompost, earthworm secretions, earthworm eggs, decomposition products of earthworm corpses, and other earthworm-related nutrients, thereby obtaining a nutrient-rich liquid fertilizer matrix solution. Over more than ten years of practical production and use, these products have achieved results that are difficult to replace with any other liquid fertilizer, overcoming the disadvantages of low fertility and slow fertilizer efficiency of liquid organic fertilizers. They are widely used in the fields of organic vegetables, grains, fruits, tea, medicinal herbs, flowers, etc.

[0003] The above-mentioned prior art also encountered some problems during use. For example, the device's one-sided gas supply made it difficult for the gas in the porous pipe network array to escape evenly from all holes. In particular, due to the presence of a certain pressure in the tank bottom medium, there was often little gas leakage from the other side of the porous pipe network array, which affected the quality of the obtained matrix solution and production efficiency.

[0004] Therefore, in 2019, the inventor improved the above problem and obtained the utility model patent "A balanced air intake and agitation device for earthworm manure-based liquid and liquid fertilizer-based liquid" (ZL201920425961.5), which improved the single-sided air intake to a balanced air intake. Although the balanced air supply problem was solved, the following problems still existed:

[0005] 1. The vents in the porous pipe array are located in the upper half of the bottom tube, and the entire bottom tube is submerged in the earthworm leachate mixture. When gas escapes from the vents, if the pressure is too low, the agitation of the earthworm leachate mixture will not be as expected. If the pressure is too high, the airflow will simply rise, also failing to achieve the desired agitation effect. Because the desired agitation effect is not achieved, the earthworm castings in the earthworm leachate mixture gradually sink.

[0006] 2. Because the porous pipe network array is installed at the bottom of the pond, the pipes of the porous pipe network array have a diameter height, and there is a gap between the porous pipe network array and the pond bottom. The actual distance between the vents and the pond bottom is about 500 mm. As a result, the earthworm castings that sink gradually settle and accumulate at the bottom of the pond, forming a dead angle. On the other hand, the accumulation of sediment gradually blocks the lateral vents of the porous pipe network array, and only the upper vents can release air. The released air floats directly upward due to gravity, thus forming a dead angle between the pipes.

[0007] 3. Because the porous pipe network is located at the bottom of the pond, earthworm manure can easily enter the pipe network through the vents (for example, when the air flow is stopped to extract the matrix solution), causing the porous pipe network to become clogged. Once it enters, it is very difficult to clean.

[0008] 4. It is very inconvenient to discharge earthworm manure and feces out of the pool. The porous pipe network array needs to be taken out before the earthworm manure and feces can be cleaned. Moreover, the porous pipe network array will be seriously damaged after being taken out and put in several times. Summary of the Invention

[0009] The purpose of the present invention is to solve the problems that the original porous pipe network array is arranged at the bottom of the pool and the air outlet is arranged on the upper half of the pipe network, resulting in a dead angle between the bottom of the agitation pool and the pipeline, the earthworm manure cannot be agitated and boiled, the earthworm manure residue enters the porous pipe network array through the air outlet and causes blockage, and the earthworm manure residue is inconvenient to clean, resulting in low production efficiency and reduced substrate quality. The present invention provides a turbulent flow extraction, vibration and agitation device with simple structure and easy use. Not only can earthworm manure, water and air form a mixed turbulent flow to fully agitate and boil, thereby improving the quality and production efficiency of the earthworm manure substrate solution, but also can ensure that the residue no longer blocks the pipeline, the earthworm substrate solution and the earthworm manure residue can be basically and effectively separated, and the earthworm manure substrate solution in the agitation pool can be easily cleaned.

[0010] In order to achieve the above-mentioned purpose, the technical solution of the present invention is: to provide a turbulent extraction, vibration and agitation device for earthworm manure matrix solution, comprising an agitation pool, wherein the inner bottom of the agitation pool is inclined, a drain port is provided on one side of the agitation pool, and a slag discharge port is provided on the other side, the drain port is located at the high side end of the bottom of the agitation pool, and the slag discharge port is located at the low side end of the bottom of the agitation pool; an anti-blocking agitation and aeration grid is provided inside the agitation pool, and the top of the anti-blocking agitation and aeration grid is connected to the top of the agitation pool through a spring, the anti-blocking agitation and aeration grid comprises a communicating grid pipe and a vertical bronchus, and the front and rear sides of the grid pipe are symmetrically provided with a front air intake pipe and a rear air intake pipe respectively, the height of the vertical bronchus is greater than the height of the grid pipe and extends into the bottom of the pool, and a pointed mouth is provided at the lower end of the vertical bronchus, and the pointed mouth ports of the vertical bronchus are all parallel to the inner bottom of the agitation pool.

[0011] Furthermore, the grid pipeline includes an upper grid pipeline and a lower grid pipeline that are connected to each other, and the upper grid pipeline and the lower grid pipeline are both connected to and connected with the vertical bronchus; the setting of a double-layer grid pipeline can not only balance the air flow velocity in the aeration grid, but also play a role in stabilizing the overall anti-blocking and agitation aeration grid, and the lower grid pipeline can also serve as a liquid height marker.

[0012] Furthermore, the distance between the tip of adjacent vertical bronchi in the longitudinal and transverse directions is 120 to 180 mm, and the outer diameter of the vertical bronchi is 25 to 35 mm. This size design can ensure that during the vibration and agitation process, the circles formed by the activity of the tip do not overlap with each other and have a certain interval.

[0013] Furthermore, the bottom inclination of the agitation pool is 15°; if the inclination is too small, it will be difficult for the feces to flow out, and if the inclination is too large, the agitation will be unbalanced. Experimental data show that when the bottom inclination of the agitation pool is 15 degrees, it can better take into account the pros and cons of sufficient balanced agitation of the earthworm manure matrix solution and the smooth discharge of earthworm manure and feces.

[0014] Furthermore, the ratio of the distance from the drainage port to the bottom of the agitation pool to the distance to the lower grid pipeline is 1:2.5, which is consistent with the ratio of the leachate mixture formed by earthworm castings and water.

[0015] Furthermore, the cross-sectional diameter of the liquid discharge port is set to about 30 mm, which is about one tenth of the cross-sectional area of ​​the residue discharge port, ensuring that the earthworm manure residue content is below 5% when the matrix solution is extracted.

[0016] Furthermore, the distance between the pointed mouth of the vertical bronchus and the bottom of the agitation pool is 25 to 35 mm, ensuring that the earthworm castings on the bottom of the agitation pool can be fully agitated. The airflow ejected from the pointed mouth is sprayed on the bottom of the pool, forming a turbulent up and down rolling agitation of the airflow, water and earthworm castings, which prevents the earthworm castings from settling and there are no dead corners.

[0017] Furthermore, a driving mechanism is provided on the top of the anti-blocking agitation air grid, and the driving mechanism can control the pointed mouth of the vertical bronchus to move in a circular motion, spraying air on the bottom of the pool like a sweeper.

[0018] Furthermore, the driving mechanism includes a motor, an eccentric rod and a wheel. The motor is fixed to the top of the agitation pool through a motor bracket, the bottom of the motor is connected to the top of the eccentric rod through a connecting rod, the bottom of the eccentric rod is connected to the wheel, and the wheel is fixed to the top of the anti-blocking agitation and aeration grid.

[0019] Furthermore, the agitation pool is arranged on a pool seat.

[0020] The turbulent flow extraction, vibration and agitation device for earthworm castings matrix solution of the present invention has the following beneficial effects:

[0021] 1. The anti-blocking agitation air grid provided by the present invention has the vertical bronchial tip facing downward, the port parallel to the pond bottom, and the tip contracting, increasing the speed of airflow ejection. Furthermore, when the tip is buried in vermicompost, the tip will be blocked by the vermicompost. Thus, airflow will reach equilibrium in the upper grid pipe, the lower grid pipe, and the vertical bronchial pipe under equal pressure. When the pressure increases to a level sufficient to dislodge the vermicompost blocking the tip, airflow will be uniformly ejected from the tip. Once airflow is ejected from the tip, no vermicompost or vermicompost residue will accumulate in the vertical bronchial pipe. The pointed nozzle faces the bottom of the agitation tank, where the airflow sweeps the earthworm castings, stirring them together with the water and air, causing them to boil and violently roll and swirl, thus forming a turbulent mixture of air, earthworm castings, and water. This not only eliminates dead corners at the bottom of the tank where earthworm castings or fecal residue can settle, but also fully integrates, oxygenates, and activates this turbulent mixture, differentiating, separating, and decomposing organic matter and its active ingredients from the earthworm castings into the liquid. This significantly improves the quality and production efficiency of the earthworm castings substrate solution compared to existing devices.

[0022] 2. The anti-blocking agitation and aeration grid provided in the present invention is arranged above the agitation pool. Only the vertical bronchus is buried in the leachate mixture, and the pointed mouth is downward, so it is not easy for earthworm castings or feces to enter the pipeline. Even if a small amount of earthworm castings or feces enters the vertical bronchus, it will be brought out in the air flow jet, ensuring that no blockage will occur, thereby improving production efficiency.

[0023] 3. The bottom inclination of the agitation pool provided in the present invention is 15°, which ensures that after the earthworm matrix solution is extracted, the anti-blocking agitation and aeration grid is started to spray and sweep the earthworm manure and feces, and the earthworm manure and feces are smoothly discharged out of the pool; in addition, when cleaning the agitation pool, not only is it not necessary to remove the anti-blocking agitation and aeration grid, but the spraying and sweeping effect of the anti-blocking agitation and aeration grid is also utilized, which makes cleaning more convenient and can also extend the service life of the anti-blocking agitation and aeration grid.

[0036] In order to explain in detail the technical content and structural features of the turbulent flow extraction and agitation device for earthworm castings substrate solution of the present invention, further description will be given below in conjunction with the embodiments and accompanying drawings.

[0037] like Figure 1 、 2As shown in Figures 3, 4, 5, 6, 7, 8, 9, 10, and 11, the turbulent flow extraction, stirring, and agitation device for earthworm castings matrix solution of the present invention comprises an agitation pool 6 and a pool seat 11 arranged at the bottom of the agitation pool 6. The agitation pool 6 is mounted on the pool seat 11. The pool seat 11 has an average height of about 600 mm, and the agitation pool 6 has an average height of about 900 mm. A matrix solution cavity 14 is provided in the agitation pool 6. The inner bottom of the agitation pool 6 is inclined, that is, the inclination angle of the pool bottom 12 is 15°. If the inclination is too small, the earthworm castings residue will be difficult to flow out, and if the inclination is too large, the agitation will be not balanced enough. Therefore, when the inclination of the bottom of the agitation pool is 15 degrees, it can better take into account the pros and cons of sufficient and balanced agitation of the earthworm castings matrix solution and the smooth discharge of the earthworm castings residue. A liquid discharge port 13 with a diameter of about 30 mm is provided on one side of the agitation pool 6, and a slag discharge port 7 is provided on the other side. A water injection port 15 is provided on the pool wall above the liquid discharge port 13. The liquid discharge port 13 is located at the high side end of the bottom of the agitation pool 6, and the slag discharge port 7 is located at the low side end of the bottom of the agitation pool 6. The slag discharge port 7 extends about 300 mm outside the pool wall of the agitation pool body. The slag discharge port 7 is about 200 mm high and 300 mm wide. There is a pre-buried screw 10 for the port every 50 mm around the end of the slag discharge port 7. The screws 10 are evenly distributed around, about 20 in number. There is a cover plate 9 on the slag discharge port 7, and a square gasket 8 is provided between the cover plate 9 and the slag discharge port 7. There are circular holes corresponding to the screws 10 on both the square gasket 8 and the cover plate 9. During production, the corresponding circular hole of the gasket 8 is inserted into the screw 10, and then the corresponding circular hole of the cover plate 9 is inserted into the screw 10, and then tightened with a nut. After the vibration and agitation are completed, the anti-blocking agitation and aeration grid 5 is closed, and the matrix solution 9 is extracted out by the liquid discharge port 13. After extracting out the matrix solution 19, the anti-blocking agitation and aeration grid 5 is opened, and the vibration and agitation jet is used to increase the mobility of the vermicompost excrement slag 20. The bucket car (or other movable container) is placed below the slag discharge port 7, the nut is unscrewed, and the lower cover plate 9 is removed. The water content of the vermicompost excrement slag 20 remaining in the pond is about 70% (note: the original water content of vermicompost is about 30%, the organic matter is about 40%, and the earth is about 30%. The vermicompost excrement slag refers to earth and a small amount of organic matter), presents a slurry state, flows out of the slag discharge port 7 under the effect of gravity and the vibration and agitation of the anti-blocking agitation and aeration grid, flows into the bucket car, and the vermicompost excrement slag is transported away as a solid organic fertilizer base material. After the worm castings and excrement residue 20 are cleaned, the power supply is turned off, the anti-blocking agitation air-injection grid 5 stops vibrating and stirring the air jet, the cover plate 9 is covered, and the nut is tightened for use during the next production.

[0038] The ratio of the distance from the drain port 13 to the bottom of the agitation tank 6 to the distance from the lower grid pipe 5-4 is 1:2.5, which is consistent with the ratio of earthworm castings to water. The cross-sectional diameter of the drain port 13 is approximately 30 mm, which is much smaller than the cross-sectional area of ​​the residue discharge port 7. When extracting the substrate solution, the anti-blocking agitation and aeration grid 5 is in a stopped state, ensuring that the earthworm castings and feces content of the extracted substrate solution does not exceed 5%.

[0039] An anti-blocking agitation and air-injection grid 5 is provided inside the agitation pool 6. The top of the anti-blocking agitation and air-injection grid 5 is connected to the top of the agitation pool 6 via a tension spring 16. The anti-blocking agitation and air-injection grid 5 includes an upper grid pipe 5-3, a lower grid pipe 5-4 and a vertical bronchus 5-5 that are in communication. The lower grid pipe 5-4 is connected to and communicates with the vertical bronchus 5-5. The front intake pipe 5-2 and the rear intake pipe 5-1 are symmetrically provided on the front and rear side pipes of the upper grid pipe 5-3. At the intake pipe node of the upper grid pipe 5-3, a five-way valve is used to connect the left and right side pipes, the lower vertical bronchus 5-5, the vertical and horizontal grid pipes on one side and the intake pipe on one side. Figure 7 The other four side pipes of the upper grid pipeline 5-3 are connected to the lateral vertical and horizontal grid pipes, and the left and right side pipes, the lower vertical bronchus 5-5, the four side pipes and the lateral vertical and horizontal grid pipes are connected by a four-way valve. Figure 6 As shown. The vertical and horizontal grid pipes in the middle of the upper grid pipe 5-3 connect the vertical and horizontal side pipes with the vertical bronchus 5-5 below, and are connected by a five-way valve. The four side pipes of the lower grid pipe 5-4 are connected to the lateral vertical and horizontal grid pipes, and the five-way valve connects the left and right side pipes, the vertical bronchus 5-5 below, the four side pipes and the lateral vertical and horizontal grid pipes. The vertical and horizontal grid pipes in the middle of the lower grid pipe 5-4 connect the vertical and horizontal side pipes with the upper and lower vertical bronchus, and are connected by a six-way valve, as shown. Figure 8 As shown. The height of the vertical bronchus 5-5 is greater than the height between the upper grid pipe 5-3 and the lower grid pipe 5-4, and a pointed mouth 5-6 is provided at the lower end of the vertical bronchus 5-5, and the pointed mouths 5-6 of the vertical bronchus are parallel to the inner bottom of the agitation pool 6. The pointed mouth 5-6 converges, and its area is about one-third of the cross-sectional area of ​​the vertical bronchus 5-5. The setting of this pointed mouth 5-6, on the one hand, increases the speed of the airflow ejection, and on the other hand, when it is buried in earthworm manure, the pointed mouth 5-6 will be blocked, so that the airflow will reach equilibrium in the upper grid pipe 5-3, the lower grid pipe 5-4 and the vertical bronchus 5-5 under the same pressure. When the pressure increases to a level greater than the earthworm manure blocked by the pointed mouth 5-6, the airflow will be ejected uniformly from the pointed mouth 5-6. Once the airflow is ejected from the pointed nozzles 5-6, it will sweep the earthworm castings on the bottom of the pond, stirring the earthworm castings together with water and air to boil, and violently stirring and rolling up and down, thereby forming a turbulent agitated mixture of air, earthworm castings and water. This not only ensures that there are no dead corners at the bottom of the pond where earthworm castings or feces residue are deposited, but also makes the turbulent agitated mixture of the three fully integrated, oxygenated and activated, and differentiates, separates and decomposes the organic matter and its effective components from the earthworm castings into liquid. Compared with the original device, the quality and production efficiency of the earthworm castings substrate solution are greatly improved (such as Figure 10As shown). When in use, the anti-blocking agitation and aeration grid 5 is placed in the agitation pool 6, and the pointed mouths 5-6 point to the bottom of the pool. The distance between the pointed mouths 5-6 of adjacent vertical bronchi in the longitudinal and transverse directions is 120 to 180 mm, and the outer diameter of the vertical bronchus 5-5 is 25 to 35 mm. The design of this size can ensure that during the vibration and agitation process, the circles formed by the movement of the pointed mouths do not overlap with each other and have a certain interval. The distance between the pointed mouths 5-6 of the vertical bronchi and the inner bottom of the agitation pool 6 is 25 to 35 mm, ensuring the formation of a turbulent agitated mixture of gas, earthworm castings and water, and the earthworm castings at the bottom of the agitation pool can be fully agitated, boiled and oxygenated, and there is no dead angle.

[0040] A driving mechanism is provided at the top of the anti-blocking agitation and aeration grid 5, and the driving mechanism can control the pointed tips of the vertical bronchial tubes to move in a circular motion, spraying air on the bottom of the pool like a sweeper. The driving mechanism includes a motor 2, an eccentric rod 17, a wheel 4, a motor bracket 1, a connecting rod 3 and a frame 18. The motor 2 is fixed to the top of the agitation pool 6 through the motor bracket 1, and the bottom of the motor 2 is connected to the top of the eccentric rod 17 through the connecting rod 3. The bottom of the eccentric rod 17 is connected to the wheel 4, and the wheel 4 is fixed to the top of the anti-blocking agitation and aeration grid 5. The frame 18 is fixed to the upper port of the agitation pool 6. The anti-blocking agitation and aeration grid 5 is supported by 8 tension springs 6 on the four sides, so that the lower end pointed tips 5-6 of the anti-blocking agitation and aeration grid 5 are about 30 mm away from the bottom 12 of the agitation pool 6. The plane formed by each lower end pointed tip 5-6 is parallel to the bottom surface 12 of the pool.

[0041] When the motor 2 rotates, it drives the connecting rod 3 to rotate, and the connecting rod 3 drives the eccentric rod 17 to rotate. The rotation of the eccentric rod 17 drives the anti-blocking agitation and aeration grid 5 to vibrate and stir. During the vibration and stirring process of the anti-blocking agitation and aeration grid 5, each of the sharp nozzles 5-6 is drawing a circle. When compressed gas is input into the air intake pipe, the sharp nozzles 5-6 spray air on the bottom of the pool like a sweeper. The position of the eccentric rod 17 in the wheel 4 is controlled to ensure the amplitude of the vibration (the radius is about one-third of the distance between the two sharp nozzles 5-6), and the distance between the anti-blocking agitation and aeration grid 5 and the wall of the agitation pool 6 is kept at about one-half of the distance between the two sharp nozzles 5-6.

[0042] The working process of the turbulent flow extraction, vibration and agitation device for earthworm castings substrate solution of the present invention is as follows:

[0043] 1. Open the water inlet 15, add water in a ratio of 2.5 to earthworm castings 1 by volume, and start the motor 2 at the same time. The motor 2 drives the anti-blocking agitation and aeration grid 5 to vibrate and stir continuously. At the same time, turn on the compressed air pump outside the device. The compressed air pump inflates the anti-blocking agitation and aeration grid 5, and the air flow passes through the lower end sharp mouth 5-6 of the anti-blocking agitation and aeration grid 5 and sprays air to the bottom of the agitation pool 6. While vibrating and spraying air, water and earthworm castings are added in a ratio of 2.5:1 until the lower grid pipe 5-4 of the anti-blocking agitation and aeration grid 5 is flush with the liquid, and then stop adding water and earthworm castings.

[0044] 2. After the spraying and vibration agitation are completed, turn off the motor 2, turn off the compressed air pump, open the drain port, and start the pump to pump the earthworm castings matrix solution 19 into the filter device.

[0045] 3. After the matrix solution is pumped out by the pump, close the drain port, stop the pump, open the cover plate 9 of the slag discharge port 7, start the compressed air pump, start the motor 2, and the anti-blocking agitation and aeration grid 5 in the agitation pool 6 will work. The earthworm manure residue will increase its fluidity and gain kinetic energy under the sweeping airflow ejected from the sharp nozzles 5-6. Under the dual action of kinetic energy and potential energy, it will smoothly flow out of the slag discharge port 7 and into the cart.

[0046] Experimental data and theoretical analysis of a vibrating agitation tank with a bottom inclination set to 15°.

[0047] There are many factors closely related to the slope of the pool bottom, but the most important ones are the smooth discharge of feces and the balance of water pressure at the tip. Compared with these two factors, the influence of other factors can be ignored.

[0048] In terms of smooth excrement discharge, the larger the angle, the better; in terms of balanced water pressure at the pointed mouth, the smaller the angle, the better. These two factors are in conflict. How to find a reasonable balance between these two contradictions is one of the key points of this application.

[0049] According to the experimental data on the relationship between the time it takes to discharge feces and the angle of inclination of the pool bottom (Table 1 below), the time is less than ten minutes after the inclination angle reaches 35°. Therefore, increasing the angle further is of little significance. Therefore, the angle analysis is limited to between 0° and 35°.

[0050] Table 1 Comparison test of the tilt angle of the bottom of the vibration agitation pool and the time required to clean the earthworm manure residue

[0051] Tilt angle 0° 5° 10° 15° 20° 25° 30° 35° With spray sweep ＞3h 105m 63m 38m 25m 17m 12m 9m No spraying ＞24h 762m 407m 213m 138m 75m 40m 25m

[0052] Under the same conditions, when discharging manure residue, such as when there is a jet of an air grid pointed nozzle, the main factor is gravity. The relationship between gravity and angle is a sine relationship, with a minimum of 0 and a maximum of 1, which is 0.574 at 35°. This is basically consistent with the test data above. That is, at 35°, the gravity effect is 0.574, plus the manure residue has a moisture content of about 70%, and with the jet of air from the pointed nozzle, the fluidity is already extremely high, and the discharge is very smooth. Therefore, we set the slag discharge effect at 0° as the worst and the slag discharge effect at 35° as the best. Taking the best 35° as the basic data, the sine values ​​of different angles are used as the denominator to divide them to get the difference-to-best ratio, as shown in Table 2 below.

[0053] Table 2 Relationship between earthworm manure discharge and the bottom tilt angle of the vibration agitation tank under natural gravity

[0055] As for the balance of water pressure at the spout, if it is balanced, the vibration and agitation will be balanced and the effect will be best; if it is unbalanced, the vibration and agitation will be unbalanced and the effect will be poor. The water pressure difference at the spout is related to the tangent value of the pool bottom inclination. The difference between the shallowest and deepest points at different angles is in a tangent relationship. Table 3 below is analyzed based on the cross-sectional area of ​​the agitation pool of 1 meter * 1 meter and the average water depth at the lower grid of 0.98 meters. The best setting is when the pool bottom inclination is 0°, the tangent value is 0, and the water pressure at the shallowest and deepest spouts is 0.980N / cm2. When the pool bottom inclination is 35°, it is set to be poor, the tangent value is 0.700, and the water pressure at the deepest point is 2.111 times that of the shallowest. We use the ratio of the shallowest and deepest water pressures at different angles as the difference-to-best ratio data analysis, and this analysis is basically consistent with the tangent data analysis. Difference-to-Best Ratio = (2.111-1.000)*A / (2.111-A), where A represents the water pressure ratio at different angles. This leads to the data analysis in Table 3 below.

[0056] Table 3 Comparison of the inclination angle of the bottom of the vibration agitation pool and the water pressure difference at the tip of the aeration grid

[0057]

[0058] like Figure 11 As shown in the vibration and agitation difference and ratio comparison curve, the optimal balance point of the two factors should be around 16°. Considering that the influence of water pressure balance on quality is greater than the smoothness of slag discharge, one is quality and the other is efficiency, and quality is more important than efficiency, so the optimal pool bottom inclination is 15°.

[0059] The above disclosure is merely a preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention still fall within the scope of the present invention.
