Description

Technical Field

[0001] This utility model relates to the field of testing technology for integrated agricultural water and fertilizer equipment, specifically a mother liquor tank for testing integrated agricultural water and fertilizer equipment. Background Technology

[0002] Currently, integrated water and fertilizer technology in agriculture is widely used. Integrated water and fertilizer equipment can precisely configure fertilizers, control the concentration and flow rate of irrigation fertilizer solutions, and achieve uniformity of water and fertilizer application in time and space, effectively improving water and fertilizer utilization efficiency, reducing fertilizer waste, and thus alleviating non-point source pollution problems caused by agricultural production. However, the performance of current integrated water and fertilizer equipment varies greatly, and there is a lack of standardized testing methods and automated performance testing platforms. A testing platform can provide stable and standardized water source testing conditions for the operation and testing of integrated water and fertilizer equipment, provide stable and uniform fertilizer mother liquor, and monitor and record key data such as pipeline flow rate, pressure, mother liquor flow rate, and fertilizer concentration in real time.

[0003] Currently, the fertilizer mother liquor tank used in the testing platform is a general-purpose barrel-shaped container, which has three main problems: First, when changing the type of mother liquor, residual liquid and impurities cannot be completely drained, affecting the conditions of the next set of tests; second, online flow detection is difficult, as commonly used pipeline flow sensors have large errors, and the high concentration of mother liquor easily crystallizes and deposits at sensitive elements, affecting detection; third, mixing the mother liquor requires manual stirring or motor-driven paddle stirring, and motor-driven paddle stirring can block the fertilizer inlet, limiting the efficiency of fertilizer addition, and the mixing time is too long in low-temperature winter tests, affecting the test progress. While the overall automation level of the integrated water and fertilizer equipment testing platform is relatively high, the mother liquor tank device remains a weakness, and there is an urgent need for a mother liquor tank device that can achieve complete drainage of residual material, accurate flow monitoring, and rapid fertilizer dissolution. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a mother liquor tank for testing integrated agricultural water and fertilizer equipment. The bottom is designed with a convex frustum shape and a three-way connector. Instead of the traditional motor-driven paddle stirring, a submersible pump is used for stirring. A heating device and a pressure sensor are added, which improves the mixing and dissolving speed of water and fertilizer and the detection efficiency. This solves the technical problems of low mother liquor mixing efficiency, difficult cleaning of the mother liquor tank, and difficult testing in existing technologies.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a mother liquor tank for testing agricultural water and fertilizer integration equipment, comprising a mixing tank body and a chassis. The bottom of the mixing tank body is a convex frustum shape, and a three-way connector is installed at the center of the bottom plane of the frustum. A weighing base is installed on the bottom surface of the convex frustum shape of the mixing tank body, and the weighing base is located above the chassis. A mixing device is installed on one side of the bottom of the mixing tank body, and a heating device is wrapped around the outer wall of the mixing tank body.

[0008] Furthermore, the main body of the mixing tank is a cylinder made of black hard plastic, and the diameter of the upper opening of the mixing tank is not less than 80% of the cross-sectional diameter of the main body.

[0009] Furthermore, a water inlet is installed on the shoulder of the cylindrical body of the mixing tank. An elbow is provided at the end of the water inlet. The water inlet's water inlet direction is perpendicular to the diagonal line of the shoulder, so that the water inlet naturally forms a counterclockwise rotation, which accelerates the dissolution of fertilizer.

[0010] Furthermore, one side of the tee connector is connected to the suction port of the device under test, and the other side is connected to a valve to the drainage system.

[0011] Furthermore, a liquid level display is installed on one side of the main body of the mixing tank for observing the mother liquor level of the main body of the mixing tank. A pair of liquid level warning sensors are symmetrically arranged at the upper and lower ends of the liquid level display for issuing an alarm when the mother liquor level of the main body of the mixing tank is too high or too low.

[0012] Furthermore, the weighing base is annular with a sloping inner side. The inner surface of the weighing base fits the convex frustum bottom surface of the mixing tank body. A circular hole is provided in the center of the convex frustum bottom for easy collection of undissolved impurities and discharge from the impurity outlet. The circular hole corresponding to the bottom of the mixing tank body is used to install the three-way connector.

[0013] Furthermore, the mixing device includes a placement platform installed at the bottom of the mixing tank body. The height of the placement platform is one-fifth of the height of the mixing tank body. A submersible pump is fixedly installed on the placement platform. The outlet of the submersible pump is along the oblique tangent of the convex frustum shape at the bottom of the mixing tank body, causing the mother liquor in the mixing tank body to rotate counterclockwise, thereby accelerating dissolution.

[0014] Furthermore, the heating device includes an electric heating film wrapped around the outer wall of the mixing tank body, the electric heating film being located in one-third of the mixing tank body, for accelerating the dissolution of the mother liquor in a low-temperature environment.

[0015] Furthermore, three or four pressure sensors are evenly distributed between the weighing base and the chassis. The pressure sensors are used to detect the mass change of the mother liquor tank in real time through bridging. By monitoring the mass change of the mother liquor in the mother liquor tank in real time through data, the amount of mother liquor used can be calculated by the difference, thereby monitoring the amount of fertilizer absorbed by the water-fertilizer integrated machine.

Through the improvement of the physical structure, the mixing and dissolution of water and fertilizer is accelerated, and the work efficiency is improved.

[0019] 2. The mother liquor tank has been equipped with a heating device, which can accelerate the dissolution of the mother liquor in low-temperature environments, further improving work efficiency.

[0020] 3. Three or four pressure sensors are evenly distributed between the weighing base of the mother liquor tank and the chassis 2.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 A mother liquor tank for testing integrated agricultural water and fertilizer equipment includes a mixing tank body 1 and a chassis 2. The main body of the mixing tank body 1 is cylindrical and made of black hard plastic. The diameter of the upper opening of the mixing tank body 1 is not less than 80% of the cross-sectional diameter of the main body. A water inlet 7 is installed on the shoulder of the upper end of the mixing tank body 1. An elbow is provided at the end of the water inlet 7. The water inlet direction of the water inlet 7 is perpendicular to the diagonal line of the shoulder, so that the water inlet naturally forms a reverse flow. The clock hand rotates, accelerating fertilizer dissolution. The bottom of the mixing tank body 1 is a convex frustum shape, with a three-way connector 3 installed at the center of the bottom plane of the frustum. One side of the three-way connector 3 is connected to the suction port 8 of the device to be tested, and the other side is connected to a valve to the drainage system. A weighing base 4 is installed on the convex frustum bottom surface of the mixing tank body 1, located above the base 2. The weighing base 4 is annular, with a sloping inner surface. The inner surface of the weighing base 4 is flush with the mixing tank body 1. The bottom surface of the main body 1 of the liquid tank fits into the lower convex frustum shape. A circular hole is opened in the center of the bottom of the lower convex frustum shape to facilitate the collection of undissolved impurities and their discharge from the impurity outlet. A three-way connector 3 is installed in the corresponding circular hole at the bottom of the main body 1. A mixing device 5 is installed on one side of the bottom of the main body 1 of the liquid tank. The mixing device 5 includes a placement platform 501 installed at the bottom of the main body 1 of the liquid tank. The height of the placement platform 501 is one-fifth of the height of the main body 1 of the liquid tank. A submersible pump 502 is fixedly installed on the placement platform 501. The outlet of the submersible pump 502 is along the oblique tangent direction of the lower convex frustum shape at the bottom of the main body 1 of the liquid tank, so that the mother liquor in the main body 1 of the liquid tank rotates counterclockwise to accelerate dissolution. A heating device 6 is wrapped around the outer wall of the main body 1 of the liquid tank. The heating device 6 includes an electric heating film 601 wrapped around the outer wall of the main body 1 of the liquid tank. The electric heating film 601 is located in one-third of the area of ​​the main body 1 of the liquid tank and is used to accelerate the dissolution of the mother liquor in a low-temperature environment.

[0026] In the above-described embodiments, a liquid level display 9 is installed on one side of the mixing tank body 1 to observe the mother liquor level of the mixing tank body 1. A pair of liquid level warning sensors 10 are symmetrically arranged at the upper and lower ends of the liquid level display 9 to trigger an alarm when the mother liquor level of the mixing tank body 1 is too high or too low.

[0027] In the above-mentioned embodiment, three or four pressure sensors 11 are evenly distributed between the weighing base and the chassis 2. The pressure sensors 11 are used to detect the mass change of the mother liquor tank in real time through bridging. By monitoring the mass change of the mother liquor in the mother liquor tank in real time through data, the amount of mother liquor used can be calculated by the difference, and the amount of fertilizer absorbed by the water and fertilizer integrated machine can be monitored.

[0028] The working principle of the above embodiments is as follows:

[0029] During use, the operator injects water into the inlet 7 of the mixing tank body 1. The water naturally rotates counterclockwise at the bottom of the mixing tank body 1. At the same time, fertilizer is put into the tank from the top opening. After the submersible pump 502 is turned on, it draws in water, and the water generates a turbine along the tank wall to mix the water and fertilizer. If the temperature is low, the electric heating film 601 is used to heat the water and fertilizer to promote dissolution. The suction port 8 of the device to be tested on one side of the three-way connector 3 is connected to the fertilizer suction pipe, which is connected to the integrated water and fertilizer machine. The dissolved and mixed water and fertilizer in the tank is sucked into the integrated water and fertilizer machine for testing. After the work is completed, the waste liquid is discharged through the valve on the other side of the three-way connector 3, which is connected to the drainage system. This facilitates quick slag removal, cleaning, and replacement of the mother liquor.
