Description

Technical Field

[0001] The invention belongs to the technical field of fertilizer production, and in particular relates to a fully enclosed preparation device and method for humic acid water-soluble fertilizer. Background Art

[0002] The existing production process of humic acid water-soluble fertilizer mainly uses high-quality humic acid raw materials and an appropriate amount of water to dissolve them. The humic acid raw materials include natural humic acid or synthetic humic acid. The humic acid content is generally required to be above 70%. Microbial anaerobic fermentation is carried out in an anaerobic environment. After fermentation is completed, solid or liquid fertilizer is obtained through filtration and drying.

[0003] Because humic acid water-soluble fertilizers contain a variety of organic substances and nutrients, these substances easily react with oxygen and moisture in the air in an open environment, resulting in a decrease in product quality. Furthermore, certain components in humic acid water-soluble fertilizers (such as humic acid) can be harmful to human health, and leaks of gases such as ammonia and carbon dioxide can pollute the surrounding environment. Therefore, sealed operations can ensure product quality, reduce contact between certain components in humic acid water-soluble fertilizers and workers, and mitigate safety risks.

[0004] During the sealed production process, since humic acid raw materials include organic substances such as plant residues, animal remains, algae, and microorganisms, it is difficult to promptly clear the transport pipeline when residual impurities become clogged, affecting the company's production efficiency. Therefore, the present invention provides a fully enclosed device and method for preparing humic acid water-soluble fertilizer that can ensure smooth pipeline operation. Summary of the Invention

[0005] The purpose of the present invention is to provide a fully enclosed preparation device and method for humic acid water-soluble fertilizer, which can automatically dredge the pipeline according to the blockage situation and ensure the production efficiency.

[0006] In order to achieve the above object, the technical solution of the present invention is as follows:

[0007] A fully enclosed preparation device for humic acid water-soluble fertilizer includes a fermentation tank, a feed pipe and an exhaust pipe are connected to the top of the fermentation tank; a solenoid valve is connected to the exhaust pipe, and an end of the exhaust pipe away from the fermentation tank is connected to a gas storage tank;

[0008] The bottom of the fermentation tank is connected to a drainage pipe, which includes an expansion portion and a fixed portion arranged alternately. An air guide pipe with a flow direction opposite to the liquid flow is provided outside the drainage pipe, and one end of the air guide pipe is connected to the air storage tank. The air guide pipe is also connected to a peristaltic pump for generating continuous thrust, and the top of the peristaltic pump is against the expansion portion.

[0009] A reversing mechanism for switching the direction of gas flow in the air pipe is also provided at the junction of the air pipe and the gas storage tank. When the expansion part abuts against the air pipe, the reversing mechanism connects the air pipe with the peristaltic pump.

[0010] The following beneficial effects are achieved by adopting the above scheme: during the sealed fermentation process, gases such as ammonia and carbon dioxide produced by anaerobic fermentation are collected in the gas storage tank. When the discharge pipe is blocked, the expansion part pressurizes the reversing mechanism to connect the air guide tube with the peristaltic part, so that the gas accumulated inside the gas storage tank continues to push the peristaltic pump to rotate, so as to continuously pressurize the expansion part, thereby forming an auxiliary driving force to promote the clearing of debris blocked in the discharge pipe, so that it can automatically clear the pipe according to the blockage situation to ensure the production efficiency.

[0011] Furthermore, the air guide tube is connected to a plurality of connecting tubes, the connecting tubes are located between the air guide tube and the peristaltic pump, and the connecting tubes are also connected to a one-way valve;

[0012] The gas outlet end of the gas storage tank is connected to a three-phase solenoid valve, one end of the three-phase solenoid valve is connected to the air guide pipe, and the other end of the three-phase solenoid valve is connected to the connecting pipe; the three-phase solenoid valve is electrically connected to a controller for actively controlling the connectivity of the three-phase solenoid valve.

[0013] Beneficial effect: The controller is used to realize artificial and autonomous control of gas circulation to control the peristaltic pump to work, so as to actively clean the inside of the drainage pipe to ensure the smooth flow of the inside of the drainage pipe.

[0014] Furthermore, the fixing portion includes a circular fixing plate, an airtight barrel is provided below the fixing plate, and symmetrically arranged pistons are slidably fitted in the airtight barrel; an air outlet pipe is connected to the center of the airtight barrel, and an end of the air outlet pipe away from the airtight barrel is connected to the air outlet end of the peristaltic pump;

[0015] There are fixed blocks on both sides of the opening of the fixed plate, and a guide rod is provided between the fixed block and the piston, one end of the guide rod is fixedly connected to the piston, and the other end of the guide rod is slidably matched with the fixed block; and a guide block is fixedly connected to the guide rod, and a spring is provided between the guide block and the fixed plate, one end of the spring is against the guide block, and the other end of the spring is fixedly connected to the fixed plate; a steel spring is provided between the guide block and the fixed block to limit the movement of the guide rod.

[0016] Beneficial effects: The air pressure generated by the peristaltic pump pushes the piston to move, thereby pushing the guide block to move, thereby adjusting the clamping effect of the spring and steel spring on the fixed plate, thereby adjusting the opening size of the fixed plate, loosening impurities blocking the inside of the drainage pipe, and widening the diameter of the inside of the fixed part, thereby ensuring the smooth flow of the drainage pipe.

[0017] Furthermore, the gas storage tank is also connected to an air compressor for adjusting the air pressure inside the gas storage tank; an air pressure sensor is provided in the fermentation tank, and the air pressure sensor is used to measure the real-time air pressure data in the fermentation tank in real time and send the real-time air pressure data to the controller;

[0018] The controller is also used to compare the real-time air pressure data with the set rated air pressure value. If the real-time air pressure data is greater than or equal to the rated air pressure value, a start command is sent to the solenoid valve; if the real-time air pressure data is less than the rated air pressure value, an adjustment command is sent to the air compressor.

[0019] Beneficial effects: By determining the real-time air pressure data, it is easy to assist in judging whether there is any abnormality in anaerobic fermentation and ensure product quality; it is also easy to control the air compressor to maintain the air pressure inside the gas storage tank, so as to facilitate the subsequent rotation of the peristaltic pump.

[0020] Furthermore, the peristaltic pump includes a housing, a sealed chamber is formed in the housing, a plurality of blades are rotatably provided in the sealed chamber for dividing the sealed chamber, an air inlet end of the sealed chamber is connected to an air guide pipe, and an air outlet end of the sealed chamber is connected to an air outlet pipe;

[0021] A placement opening is provided on the top of the shell, a rubber layer seal is provided between the placement opening and the sealed chamber, and the expansion part is located in the placement opening; when the fan blade moves to the top, the fan blade and the expansion part are against each other; when the fan blade and the placement opening are level, the fan blade and the expansion part are separated.

[0022] Beneficial effect: The gas in the air duct continuously drives the fan blades in the sealed chamber to rotate, so as to drive the fan blades to continuously contact the expansion part, thereby generating a circulating thrust and continuously pressurizing the inside of the drain pipe to clear the blockage.

[0023] Furthermore, the reversing mechanism includes a telescopic rod with adjustable length, and a baffle for limiting the deformation of the air guide tube is provided on the side of the air guide tube away from the liquid discharge tube;

[0024] The telescopic rod is located in the air guide tube, and both ends of the telescopic rod are hinged to the inside of the air guide tube. The end of the telescopic rod close to the baffle is located above the connecting tube;

[0025] A plug is slidably fitted in the connecting tube, and a push rod is provided between the plug and the telescopic rod;

[0026] When the airway tube is in a normal state, the plug is located in the connecting tube; when the airway tube is squeezed by the expansion part, the plug is located in the airway tube.

[0027] Beneficial Effect: When the expansion section deforms due to a blockage, the fixed section restricts the drainage tube, allowing the accumulated fermentation liquid to push the expansion section and apply pressure to the airway tube. The airway tube is restrained by the baffle on the other side and cannot move, causing the diameter of the airway tube at the blocked point to decrease. The deformation of the airway tube drives the telescopic rod to move. This movement removes the plug, allowing the compressed gas to accelerate the rotation of the peristaltic pump blades, thereby ensuring the drainage tube is unblocked.

[0028] Furthermore, pressure sensors are fixedly connected to both sides of the plug, and the pressure sensors are used to measure the pressure value at the current time and send the pressure value to the controller;

[0029] The controller is further configured to compare the applied pressure value with a set rated value, and if the applied pressure value is greater than the rated value, record the number of changes, and if the applied pressure value is less than the rated value, send a maintenance instruction to the controller;

[0030] During the current interval, the controller calculates the average value of the number of changes corresponding to all pressure sensors and compares the number of changes corresponding to each pressure sensor with the average value. If the number of changes is greater than the average value, the controller adds an abnormal mark to the pressure sensor; if the number of changes is less than the average value, the controller adds a normal mark to the pressure sensor.

[0031] Beneficial effect: The pressure value detected by the pressure sensor is used to judge the blockage situation at various locations, and the blockage change situation at a local position of the drainage pipe is determined by the number of changes, so as to facilitate subsequent cleaning of the drainage pipe or adjustment of the clamping condition of the fixed part.

[0032] Furthermore, the guide block is threadedly connected to the guide rod, and two sides of the fixed block are fixedly connected by bolts.

[0033] Beneficial effect: The guide block is threadedly connected to the guide rod to facilitate adjustment of the position of the guide block on the guide rod, and then the position of the fixed block is adjusted by loosening the bolt to adjust the initial clamping force of the spring and steel spring on the fixed plate, so as to facilitate subsequent loosening and adjustment of the drain pipe.

[0034] Furthermore, an indicator light is provided on the fixing portion, and the indicator light is electrically connected to the controller.

[0035] Beneficial effect: The indicator light can be used to easily identify the location of abnormalities in the drainage pipe and handle them accordingly.

[0036] Furthermore, a fully enclosed preparation method of humic acid water-soluble fertilizer, according to the preparation method of the fully enclosed preparation device of humic acid water-soluble fertilizer, comprises the following steps: step 1, adding humic acid raw materials into a sealed tank through a feed pipe according to a weight ratio; and collecting real-time air pressure data during the standard fermentation time through an air pressure sensor;

[0037] Step 2: The controller compares the real-time air pressure with the set rated air pressure value. If the real-time air pressure data is greater than or equal to the rated air pressure value, a start command is sent to the solenoid valve. If the real-time air pressure data is less than the rated air pressure value, an adjustment command is sent to the air compressor. At the same time, the controller records the fermentation abnormality command.

[0038] Step 3: After the anaerobic fermentation is completed, the fermentation liquid is transported through the drainage pipe. The abnormal mark or normal mark sent by the controller based on the pressure value of the pressure sensor is used to start the indicator light at the abnormal mark position; then, based on the guidance of the indicator light, the position of the guide block on the guide rod is manually adjusted.

[0039] Beneficial Effects: By comparing air pressure to ensure air pressure stability, the system sends instructions for abnormal fermentation to check the humic acid raw materials and fermentation conditions to ensure product quality. Indicator lights are used to control the diameter changes at various locations on the drainage pipe to ensure smooth drainage and production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

One end of the steel spring 342 abuts against the guide block 34, and the other end abuts against the fixed block 35. In another embodiment, the guide block 34 is threadedly connected to the guide rod 33, and the two sides of the fixed block 35 are fixedly connected by bolts.

[0053] The air duct 5 is also connected to several connecting pipes 51, which are located between the air duct 5 and the peristaltic pump 4. The connecting pipe 51 is also connected to a one-way valve; and the air outlet end of the gas storage tank is connected to a three-phase solenoid valve (not shown in the figure), one end of the three-phase solenoid valve is connected to the air duct 5, and the other end of the three-phase solenoid valve is connected to the connecting pipe 51; the three-phase solenoid valve is electrically connected to a controller for actively controlling the connectivity of the three-phase solenoid valve.

[0054] In addition, an indicator light is provided on the fixing portion 3, and the indicator light is electrically connected to the controller.

[0055] The junction of the air duct 5 and the gas storage tank is also provided with a reversing mechanism for switching the direction of gas flow in the air duct 5, and the reversing mechanism includes a telescopic rod 52 of adjustable length. A baffle for limiting the deformation of the air duct 5 is provided on the side of the air duct 5 away from the discharge pipe 2; the telescopic rod 52 is located in the air duct 5, and both ends of the telescopic rod 52 are hinged to the inside of the air duct 5, and the end of the telescopic rod 52 close to the baffle is located above the connecting tube 51; and a plug 53 is slidably fitted in the connecting tube 51, and a push rod is provided between the plug 53 and the telescopic rod 52; the two ends of the push rod are respectively hinged to the top of the plug 53 and the telescopic rod 52, and the bottom of the plug 53 is arc-shaped; when the air duct 5 is in normal state, the plug 53 is located in the connecting tube 51; when the air duct 5 is squeezed by the expansion part 21, the plug 53 is located in the air duct 5.

[0056] A fully enclosed method for preparing humic acid water-soluble fertilizer includes the following steps: Step 1: adding humic acid raw materials into a sealed tank through a feed pipe 11 according to a weight ratio; and using a pressure sensor to collect real-time pressure data during a standard fermentation time. Determining the real-time pressure data facilitates determining whether anaerobic fermentation is abnormal, thereby ensuring product quality. It also facilitates controlling the air compressor to maintain the pressure inside the gas storage tank, thereby facilitating the subsequent rotation of the peristaltic pump 4. Simultaneously, gases such as ammonia and carbon dioxide produced by the anaerobic fermentation are collected by the gas storage tank.

[0057] Step 2: The controller compares the real-time air pressure with the set rated air pressure value. If the real-time air pressure data is greater than or equal to the rated air pressure value, a start command is sent to the solenoid valve. If the real-time air pressure data is less than the rated air pressure value, an adjustment command is sent to the air compressor. At the same time, the controller records the abnormal fermentation command. While ensuring the stability of the air pressure by comparing the real-time air pressure data, the humic acid raw materials and fermentation conditions are checked by sending the abnormal fermentation command to ensure product quality.

[0058] Step 3: After anaerobic fermentation is complete, the fermentation liquid is transported through the drainage pipe 2. When the drainage pipe 2 becomes clogged and the expansion portion 21 deforms due to the blockage, the fixed portion 3 restricts the drainage pipe 2, causing the accumulated fermentation liquid to push the expansion portion 21 to apply pressure to the airway pipe 5. The airway pipe 5 is restricted by the baffle on the other side and cannot move, causing the diameter of the airway pipe 5 to decrease at the blocked point. The deformation of the airway pipe 5 drives the telescopic rod 52 to move. After the telescopic rod 52 moves, the plug 53 is removed, allowing the compressed gas to accelerate the rotation of the blades in the peristaltic pump 4, thereby ensuring the unclogged drainage pipe 2.

[0059] When the connecting tube 51 is connected to the air duct 5, the gas within the air duct 5 continuously drives the fan blades in the sealed chamber to rotate, pushing the fan blades into constant contact with the expansion portion 21, generating a circulating thrust that continuously pressurizes the interior of the drainage pipe 2 and clears the blockage. Simultaneously, the gas compressed by the peristaltic pump 4 continuously pressurizes the piston, which in turn moves the guide block 34, adjusting the clamping effect of the spring 341 and the steel spring 342 on the fixed plate 31 to adjust the opening size of the fixed plate 31, loosening impurities blocking the drainage pipe 2, and widening the diameter of the fixed portion 3 to ensure the smooth flow of the drainage pipe 2.

[0060] The controller then sends an abnormal mark or a normal mark based on the pressure value of the pressure sensor 6 to start the indicator light at the abnormal mark position; then, based on the guidance of the indicator light, the position of the guide block 34 on the guide rod 33 is manually and actively adjusted to control the diameter change of each position on the drainage pipe 2 to ensure the smooth flow of the drainage pipe 2.

[0061] Example 2

[0062] The difference from the above embodiment is that the gas storage tank is also connected to an air compressor for adjusting the air pressure inside the gas storage tank; an air pressure sensor is provided in the fermentation tank 1, which is used to measure the real-time air pressure data in the fermentation tank 1 in real time and send the real-time air pressure data to the controller.

[0063] The controller is also used to compare the real-time air pressure data with the set rated air pressure value. If the real-time air pressure data is greater than or equal to the rated air pressure value, a start command is sent to the solenoid valve; if the real-time air pressure data is less than the rated air pressure value, an adjustment command is sent to the air compressor.

[0064] For example, during the anaerobic fermentation of the same humic acid raw material, the differences in material particles and fermentation conditions (such as temperature, water content, etc.) often lead to different fermentation gases. By determining the real-time air pressure data, it is convenient to assist in judging whether there is any abnormality in the anaerobic fermentation and ensure product quality; it is also convenient to control the air compressor to maintain the air pressure inside the gas tank, so as to facilitate the subsequent rotation of the peristaltic pump 4.

[0065] Example 3

[0066] The difference from the above embodiment is that pressure sensors 6 are fixedly connected to both sides of the plug 53, and the pressure sensors 6 are used to measure the pressure value at the current time and send the pressure value to the controller; the controller is also used to compare the pressure value with the set rated value. If the pressure value is greater than the rated value, the number of changes is recorded once; if the pressure value is less than the rated value, a maintenance instruction is sent to the controller; within the current interval, the controller is used to calculate the average value of the corresponding number of changes of all pressure sensors 6, and compare the number of changes corresponding to each pressure sensor 6 with the average value. If the number of changes is greater than the average value, the controller adds an abnormal mark to the pressure sensor 6; if the number of changes is less than the average value, the controller adds a normal mark to the pressure sensor 6.

[0067] For example, as the plug 53 continuously contacts the connecting tube 51, each change in the number of times represents a blockage. The pressure value detected by the pressure sensor 6 is used to determine the blockage status at each location. The number of changes is then used to determine the blockage change status at a local location in the drainage tube 2, facilitating subsequent cleaning of the drainage tube 2 or adjustment of the clamping condition of the fixing portion 3. At the same time, an abnormality mark or a normal mark is generated to control the operation of the indicator light, thereby marking the abnormal location.

[0068] The above is only an embodiment of the present invention, and common knowledge such as the specific structure and / or characteristics of the scheme is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the structure of the present invention, several variations and improvements can be made, which should also be regarded as the scope of protection of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.

At the same time, the controller records the fermentation abnormality command. Step 3: After the anaerobic fermentation is completed, the fermentation liquid is transported through the drainage pipe. The abnormal mark or normal mark sent by the controller based on the pressure value of the pressure sensor is used to start the indicator light at the abnormal mark position; then, based on the guidance of the indicator light, the position of the guide block on the guide rod is manually adjusted.
