Description

Technical Field

[0001] This utility model relates to the technical field of water circulation storage equipment, specifically to a fertilizer and water recycling device. Background Technology

[0002] In the development of modern agriculture, recirculating hydroponics technology, as an advanced soilless cultivation model, is gradually being widely applied. This cultivation technology breaks free from the limitations of traditional soil planting. By directly immersing the crop roots in fertile water, and using a circulation system to continuously flow the fertile water through the roots, it provides the necessary nutrients and water for crop growth, resulting in significant advantages such as a short growth cycle, high yield, and good quality.

[0003] The preparation of fertilizer solution is the core of the entire hydroponic system. It typically uses an open pond or a sealed container as the central hub, serving to store wastewater and regulate the fertilizer solution. Open ponds have a simple structure, but the wastewater is easily contaminated. Sealed containers, on the other hand, offer better protection for the fertilizer solution and better regulate its various nutrients.

[0004] In the existing technology, most tanks used for configuring and regulating fertilizer water have simple structures and more or less have the following problems: 1. After the fertilizer water is stored in the tank, some substances are prone to sedimentation under static conditions, and the fertilizer water is prone to nutrient imbalance; 2. The status of nutrients in the fertilizer water cannot be monitored in real time; 3. Due to the sealing of the tank, the internal air pressure may rise due to the gas released from the fertilizer water. If the air pressure inside the tank cannot be well controlled, most tanks do not have a good pressure regulating function. Utility Model Content

[0005] The purpose of this invention is to provide a fertilizer recycling device to solve the problem that some substances tend to settle and the fertilizer may have nutritional imbalances when it is stored in a tank and remains still.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A fertilizer and water recycling device includes a tank with a cavity inside. A return water pipe communicating with the cavity is provided on the side of the tank, and an outlet water pipe communicating with the cavity is provided at the bottom of the tank. A stirring motor is installed on the top of the tank, and the output shaft of the stirring motor extends vertically downward into the cavity. The lower end of the output shaft is connected to a stirring blade. A detection rod is installed in the cavity, and a sensor group for monitoring the water body is installed on the detection rod. A pressure pipe communicating with the cavity is installed on the top of the tank, and a pressure relief valve is installed on the pressure pipe. A pressure gauge is installed between the pressure relief valve and the tank.

[0008] A further technical solution is that the top of the tank is provided with an installation pipe that communicates with the cavity. An installation block is detachably installed on the upper end of the installation pipe. The upper end of the detection rod is connected to the lower side of the installation block inside the installation pipe. The lower end of the detection rod is placed inside the cavity, and the sensor group is installed on the lower end of the detection rod.

[0009] A further technical solution is that the sensor group includes at least one of the following: an ammonia nitrogen sensor, a conductivity sensor, a pH sensor, and a temperature sensor.

[0010] A further technical solution is to install an observation window on the side of the tank, with tempered glass installed inside the observation window.

[0011] A further technical solution is that the pressure relief valve includes a valve body and a gravity block. The valve body is vertically installed at the upper end of the pressure pipe. The valve body is provided with a pressure relief hole that runs through both the upper and lower sides. The lower end of the pressure relief hole is connected to the pressure pipe. The inner diameter of the lower end of the pressure relief hole gradually decreases from top to bottom to form a first frustum. The gravity block is columnar. The diameter of the gravity block is smaller than the diameter of the upper end of the pressure relief hole and larger than the diameter of the lower end of the pressure relief hole. The lower edge of the gravity block is set as a second frustum that fits against the first frustum. The outer wall of the gravity block is provided with several hemispheres that slide against the inner wall of the pressure relief hole.

[0012] A further technical solution is that a rubber sealing ring is provided on the first frustum surface, and the rubber sealing ring is sealed and fitted to the second frustum surface.

[0013] A further technical solution is to install a first water pump on the return water pipe and a second water pump on the outlet water pipe.

[0014] A further technical solution is to install a pressure relief pipe between the tank and the pressure relief valve, and install a manual valve on the pressure relief pipe.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. By setting a stirring motor and stirring blades, the fertilizer water in the cavity can be stirred during fertilizer water circulation, thus making the nutrients in the fertilizer water more uniform; 2. By setting a detection rod and sensor group, the state of the fertilizer water can be detected at any time, so that the operator can adjust the nutrients in the fertilizer water in a timely manner; 3. By setting a pressure gauge, the pressure in the cavity can be detected, and by setting a pressure relief valve, the pressure in the cavity can be relieved in time when the pressure in the cavity is too high, ensuring that the cavity is within a safe pressure range.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] Figures 1 to 5 The following is an embodiment of the present invention.

[0024] Example 1:

[0025] A fertilizer and water recycling device includes a tank 1, with a cavity 2 inside the tank 1. A return water pipe 3 connected to the cavity 2 is located on the side of the tank 1, and an outlet water pipe 4 connected to the cavity 2 is located at the bottom of the tank 1. A stirring motor 5 is installed at the top of the tank 1, with its output shaft vertically downwards and inserted into the cavity 2. The lower end of the output shaft is connected to a stirring blade 6. A detection rod 7 is installed inside the cavity 2, and a sensor group 8 for monitoring the water quality is installed on the detection rod 7. A pressure pipe 9 connected to the cavity 2 is installed at the top of the tank 1, and a pressure relief valve 10 is installed on the pressure pipe 9. A pressure gauge 11 is installed between the pressure relief valve 10 and the tank 1. By setting up the stirring motor 5 and the stirring blade 6, the fertilizer and water in the cavity 2 can be stirred during fertilizer and water circulation, thus making the nutrients in the fertilizer and water more uniform. By setting up the detection rod 7 and the sensor group 8, the state of the fertilizer and water can be monitored at any time, allowing operators to adjust the nutrients in the fertilizer and water in a timely manner. By setting pressure gauge 11, the pressure inside cavity 2 can be detected. By setting pressure relief valve 10, pressure can be released in time when the pressure in cavity 2 is too high, ensuring that cavity 2 is within a safe pressure range. Maintaining a certain pressure inside the wall allows for fermentation of the fertilizer solution inside cavity 2 when it is not in use, enabling the fermentation and decomposition of some biomass fertilizers.

[0026] The top of the tank 1 is provided with an installation tube 12 that communicates with the cavity 2. An installation block 13 is detachably installed at the upper end of the installation tube 12. The upper end of the detection rod 7 is connected to the lower side of the installation block 13 inside the installation tube 12, and the lower end of the detection rod 7 is placed inside the cavity 2. The sensor assembly 8 is installed at the lower end of the detection rod 7. The installation tube 12 facilitates the insertion of the detection rod 7 into the cavity 2. The inner wall of the upper end of the installation tube 12 is connected to the installation block 13 via a threaded connection. The detection rod 7 has a tubular structure, and the sensor assembly 8 can be installed inside the lower end of the detection rod 7. The wiring of the sensor assembly 8 can be arranged along the interior of the detection rod 7. A wire hole is provided in the installation block 13 to allow the wiring to pass through. The gap between the wiring and the wire hole is sealed by a sealing ring or sealant.

[0027] Sensor group 8 includes at least one of the following: an ammonia nitrogen sensor, a conductivity sensor, a pH sensor, and a temperature sensor. Different sensors can be adjusted in sensor group 8 as needed; the specific types and quantities of sensors can be adjusted according to actual requirements.

[0028] An observation window 14 is installed on the side of the tank 1, and tempered glass is installed inside the observation window 14. By setting the observation window 14, the condition inside the cavity 2 can be directly observed.

[0029] The pressure relief valve 10 includes a valve body 15 and a gravity block 16. The valve body 15 is vertically mounted on the upper end of the pressure pipe 9. A pressure relief hole 17 is provided on the valve body 15, extending through both the upper and lower sides. The lower end of the pressure relief hole 17 is connected to the pressure pipe 9. The inner diameter of the lower end of the pressure relief hole 17 gradually decreases from top to bottom, forming a first frustum 18. The gravity block 16 is cylindrical, with a diameter smaller than the upper diameter of the pressure relief hole 17 but larger than the lower diameter. The lower edge of the gravity block 16 is set as a second frustum 19 that fits against the first frustum 18. Several hemispheres 20 protrude from the outer wall of the gravity block 16, and these hemispheres 20 slide against the inner wall of the pressure relief hole 17. By utilizing the gravity of the gravity block 16 itself, the first frustum 18 and the second frustum 19 can fit together, thereby sealing the passage between the pressure relief hole 17 and the pressure pipe 9, thus sealing the cavity 2. As the pressure inside cavity 2 gradually increases, it pushes the gravity block 16 upward. When the first frustum 18 and the second frustum 19 separate, the gas in the pressure pipe 9 is discharged through the gap between the first frustum 18 and the second frustum 19, the gravity block 16, and the wall of the pressure relief hole 17, thereby reducing the pressure between cavities 2. By setting the hemisphere 20, a gap can be left between the outer wall of the gravity block 16 and the pressure relief hole 17, facilitating gas exhaust. The pressure relief structure of this application is simple, and the pressure threshold can be well adjusted by adjusting the gravity blocks 16 of different weights.

[0030] A rubber sealing ring 21 is provided on the first frustum surface 18, and the rubber sealing ring 21 is in close contact with the second frustum surface 19. By providing the rubber sealing ring 21, the gap between the first frustum surface 18 and the second frustum surface 19 can be effectively sealed, preventing leakage at this location.

[0031] A first water pump 22 is installed on the return water pipe 3, and a second water pump 23 is installed on the outlet water pipe 4. The first water pump 22 pumps the circulated fertilizer water back into the cavity 2. The second water pump 23 discharges the fertilizer water from the cavity 2 for use.

[0032] A feeding port, which communicates with the cavity 2, is provided on the upper side of the tank body 1. A sealing door 26 is provided at the position of the feeding port. The feeding port facilitates the addition of fertilizer or other substances by management personnel. The sealing door 26 effectively seals the feeding port.

[0033] Pressure pipe 9 is connected to tank 1 and pressure relief valve 10 by a pressure relief pipe 24, and a manual valve 25 is installed on the pressure relief pipe 24. By setting up the pressure relief pipe 24 and the manual valve 25, when adding materials, a portion of the gas inside the wall can be discharged through the pressure relief pipe 24 to reduce the pressure to atmospheric pressure, thereby preventing gas from rushing out when the sealing door 26 is opened.

[0034] Although the present invention has been described herein with reference to several illustrative embodiments, it should be understood that many other modifications and implementations can be devised by those skilled in the art, which will fall within the scope and spirit of the principles disclosed herein. More specifically, various variations and modifications can be made to the components and / or layout of the subject matter combination within the scope of the disclosure, drawings, and claims. Besides variations and modifications to the components and / or layout, other uses will be apparent to those skilled in the art.
