Description

Technical Field

[0001] The utility model relates to the technical field of nutrient solution preparation, and more specifically, to a purification device for nutrient solution preparation. Background Art

[0002] Nutrient solution is a formulated product synthesized using environmental biological ecological symbiosis technology and mycorrhizal symbiosis principles through processes such as biological fermentation, chemical chelation, and physical activation. Nutrient solution is the key to soilless cultivation. Different crops require different nutrient solution formulas. After preparation, the nutrient solution needs to be filtered and purified.

[0003] During the use of the existing purification device for preparing nutrient solution, the internal filter cartridge is replaced regularly to ensure the filtering and purification effect. However, when replacing the filter cartridge, several screws need to be unscrewed for disassembly, which makes the filter cartridge replacement operation more cumbersome and affects the convenience of later maintenance of the device. Based on this, the utility model designs a purification device for preparing nutrient solution to solve the above problems. Utility Model Content

[0004] The purpose of the present invention is to provide a purification device for preparing nutrient solution to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] The top end of the filter pocket is connected with the support of the filter pocket, and the bottom end of the filter pocket is connected with the support of the filter pocket.

[0007] As a preferred technical solution of the present invention, the drive assembly includes a motor and a gear. The motor is fixedly mounted on the cover, the gear is fixedly connected to the end of the drive shaft of the motor, the outside of the catheter is fixedly sleeved with a transmission gear ring, and the gear is engaged with the transmission gear ring.

[0008] As a preferred technical solution of the present invention, a shield is fixedly mounted on the upper end of the cover on the outside of the driving assembly, and the liquid guide tube passes through the top of the shield.

[0009] As a preferred technical solution of the present invention, side openings are opened on the sides of the shield, and the side openings are symmetrically distributed on both sides.

[0010] As a preferred technical solution of the present invention, an observation port is provided on the side of the liquid collecting box, and a transparent plate is provided in the observation port.

[0011] As a preferred technical solution of the present invention, the bottom end of the liquid collecting box is fixedly connected to a liquid outlet pipe, and a switch valve is provided on the liquid outlet pipe.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] The utility model allows the nutrient solution to enter the filter cartridge through the liquid inlet pipe and the liquid guide tube, and when the motor drives the gear to rotate, the transmission gear ring can drive the liquid guide tube and the filter cartridge to rotate, and the centrifugal force is used to prompt the filter cartridge to efficiently filter and purify the nutrient solution. The nutrient solution after filtering and purification can be stored in the liquid collection box. If the filter cartridge in the liquid collection box needs to be replaced, the electric push rod is used to drive the sealing cover to rise, so that the filter cartridge is outside the liquid collection box, and the L-shaped seat is pushed down until the assembly block is disengaged from the limiting groove on the inner wall of the assembly ring. The filter cartridge can be taken out downward along the outside of the liquid guide tube for replacement. Therefore, there is no need to unscrew several screws for disassembly when replacing the filter cartridge, which makes the replacement operation of the filter cartridge in the liquid collection box convenient and simple, which is conducive to improving the convenience of later maintenance of the device.

An inverted L-shaped seat 902 is slidably sleeved on the cross bar 901, and a spring 903 is fixedly connected between the liquid guide tube 9 and the inverted L-shaped seat 902. An assembly block 904 is fixedly installed on the bottom side of the inverted L-shaped seat 902, and the upper end of the filter cartridge 7 is fixedly connected to the assembly ring 701. A limiting groove 702 is provided on the inner wall of the assembly ring 701. The assembly block 904 is inserted into the limiting groove 702 to position the filter cartridge 7 outside the liquid guide tube 9. A spring 903 with a suitable elastic spring coefficient is used so that the spring 903 has a certain stiffness damping effect to ensure the stable positioning and installation of the filter cartridge 7. The liquid guide tube 9 passes through the cover 4 and extends into the filter cartridge 7, so that the nutrient solution can enter the filter cartridge 7 through the liquid inlet pipe 6 and the liquid guide tube 9.

[0021] Among them, such as Figure 4As shown, the driving assembly 8 includes a motor 801 and a gear 802. The motor 801 is fixedly mounted on the cover 4. The gear 802 is fixedly connected to the end of the driving shaft of the motor 801. The outer portion of the liquid guide tube 9 is fixedly sleeved with a transmission gear ring 905. The gear 802 is engaged with the transmission gear ring 905. When the motor 801 is used to drive the gear 802 to rotate, the transmission gear ring 905 can be used to drive the liquid guide tube 9 and the filter cartridge 7 to rotate.

[0022] Among them, such as Figure 2 As shown, a shield 402 is fixedly mounted on the upper end of the cover 4 outside the driving assembly 8 , and the liquid guide tube 9 passes through the top of the shield 402 .

[0026] The working principle of this utility model:

[0027] During use, the nutrient solution enters the filter cartridge 7 through the liquid inlet pipe 6 and the liquid guide pipe 9. When the motor 801 drives the gear 802 to rotate, the transmission gear ring 905 can drive the liquid guide pipe 9 and the filter cartridge 7 to rotate, and the centrifugal force is used to cause the filter cartridge 7 to efficiently filter and purify the nutrient solution. The nutrient solution after filtering and purification can be stored in the liquid collection box 1. The transparent plate 102 in the observation port 101 is convenient for checking the amount of nutrient solution after filtering and purification in the liquid collection box 1. When the amount of nutrient solution filtered and purified in the liquid tank 1 reaches the state to be discharged, open the switch valve 104 to discharge the nutrient solution filtered and purified in the liquid collecting tank 1. If it is necessary to replace the filter cartridge 7 in the liquid collecting tank 1, use the electric push rod 3 to drive the cover 4 to move upward so that the filter cartridge 7 is outside the liquid collecting tank 1, push down the L-shaped seat 902 until the assembly block 904 is disengaged from the limiting groove 702 on the inner wall of the assembly ring 701, and take out the filter cartridge 7 along the outer side of the liquid guide tube 9 for replacement.
