Description

Technical Field

[0001] This utility model relates to the technical field of centrifugal filters, specifically a centrifugal filter base for water and fertilizer irrigation. Background Technology

[0002] Centrifugal filters and disc filters are widely applicable to irrigation of various crops such as vegetables, fruit trees, greenhouses, flowers, tea gardens, green spaces, and open fields. They save water, save energy, improve plant quality, enhance product quality, and maintain ecological balance. Therefore, they are very convenient to use together.

[0003] For example, a centrifugal filter with authorization announcement number "CN214861781U" solves the problem of sand easily flowing back into the centrifugal filter when there is a large amount of sand in the sand storage tank. The above-mentioned centrifugal filter solves the problem of sand easily flowing back into the centrifugal filter when there is a large amount of sand in the sand storage tank by setting a conical mesh cover, a first baffle and a second baffle. The conical mesh cover and the first baffle and the second baffle are set at an angle in the sand storage tank. While not affecting the sand entering the sand storage tank, it can prevent the sand from flowing back into the centrifugal filter. Personnel can open the sand discharge port to clean the sand in the sand storage tank. Considering that the base of the existing centrifugal filter is directly fixed, it cannot be used with multiple filters. It cannot be guaranteed that the separate base can support the centrifugal filter. This makes it inconvenient to enter and exit water after connecting the centrifugal and disc filters. The connection and use of the centrifugal and disc filters is inconvenient. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that existing centrifugal filters cannot guarantee that the separate base can support the centrifugal filter, making it inconvenient for water to enter and exit after connecting the centrifugal and disc filters, and making it inconvenient to use the centrifugal and disc filters together. Therefore, a centrifugal filter base for water and fertilizer irrigation is proposed.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a centrifugal filter base for water and fertilizer irrigation, comprising a centrifugal filter and a disc filter, wherein the lower end of the disc filter is connected to an outlet pipe, the side end of the disc filter is connected to a backwash valve, the lower end of the backwash valve is connected to a sewage pipe, the side end of the backwash valve is connected to an inlet pipe, and a support mechanism is connected to the outer wall of the centrifugal filter.

[0006] Preferably, the support mechanism includes a first clamp, the inner wall of which abuts against the centrifugal filter. The first clamp is fixedly connected to a first support seat by bolts. The lower end of the first support seat is fixedly connected to a base, and the lower end of the base is fixedly connected to a foot.

[0007] Preferably, the upper end of the centrifugal filter is fixedly connected to the water outlet, and the upper end of the base is connected to a fixing mechanism.

[0008] Preferably, the fixing mechanism includes a fixing block, the lower end of which is fixedly connected to the base, the upper end of which is fixedly connected to the fixing rod, and the upper end of the fixing rod is fixedly connected to the fixing ring.

[0009] Preferably, the retaining ring is fixedly connected to the disc filter by bolts.

[0010] Preferably, the outer wall of the water inlet pipe is fixedly connected to the second clamp, the second clamp is fixedly connected to the second support seat by bolts, and the lower end of the second support seat is fixedly connected to the base.

[0011] Preferably, the end of the inlet pipe is connected to the connecting pipe, the outer wall of the inlet pipe is connected to the outlet, an inlet is installed on the outer side of the centrifugal filter, a sand discharge port is installed at the lower end of the centrifugal filter, and a flushing valve is installed on the other side of the lower end of the centrifugal filter.

[0012] The centrifugal filter base for water and fertilizer irrigation proposed in this utility model has the following advantages: by placing the centrifugal filter into the first support base, the bolt thread passes through the first clamp and the first support base to fix the base and the centrifugal filter; the bolt thread passes through the second clamp and the second support base to fix the base and the water inlet pipe; and the bolt passes through the fixing ring and the disc filter threaded connection to fix the base and the disc filter at the lower end of the fixing ring.

[0015] The present invention will be further described below with reference to the accompanying drawings: Please see Figure 1-6 In this embodiment, a centrifugal filter base for water and fertilizer irrigation includes a centrifugal filter 1 and a disc filter 2. The lower end of the disc filter 2 is connected to the water outlet pipe 3, the side end of the disc filter 2 is connected to the backwash valve 4, the lower end of the backwash valve 4 is connected to the sewage pipe 5, the side end of the backwash valve 4 is connected to the water inlet pipe 6, and a support mechanism 7 is connected to the outer wall of the centrifugal filter 1.

[0016] The support mechanism 7 includes a first clamp 701. By placing the centrifugal filter 1 into the first support seat 702 and threading bolts through the first clamp 701 and the first support seat 702, the first clamp 701 and the first support seat 702 are supported and fixed to the centrifugal filter 1. The inner wall of the first clamp 701 is pressed against the centrifugal filter 1. The first clamp 701 is fixedly connected to the first support seat 702 by bolts. The lower end of the first support seat 702 is fixedly connected to the base 703. The lower end of the base 703 is fixedly connected to the foot 704. Centrifugal filter 1 is placed into first support base 702. Bolt threads pass through first clamp 701 and first support base 702 to fix base 703 and centrifugal filter 1. Bolt threads pass through second clamp 10 and second support base 11 to fix base 703 and water inlet pipe 6. Bolt threads also pass through fixing ring 903 and disc filter 2 to fix base 703 at the lower end of fixing ring 903 and disc filter 2. This ensures that the separate base 703 can connect and install the centrifugal and disc filters, making it more convenient to connect and use the centrifugal and disc filters.

[0017] The upper end of the centrifugal filter 1 is fixedly connected to the outlet head 8. The upper end of the base 703 is connected to the fixing mechanism 9. The fixing ring 903 and the disc filter 2 are threadedly connected by bolts, so that the position between the fixing ring 903 and the disc filter 2 is fixed. The fixing mechanism 9 includes a fixing block 901. The lower end of the fixing block 901 is fixedly connected to the base 703, the upper end of the fixing block 901 is fixedly connected to the fixing rod 902, and the upper end of the fixing rod 902 is fixedly connected to the fixing ring 903.

[0018] The fixing ring 903 is fixedly connected to the disc filter 2 by bolts. The outer wall of the water inlet pipe 6 is fixedly connected to the second clamp 10. The second clamp 10 is fixedly connected to the second support base 11 by bolts. The lower end of the second support base 11 is fixedly connected to the base 703. The end of the water inlet pipe 6 is connected to the connecting pipe 12. The outer wall of the water inlet pipe 6 is connected to the water outlet 8. The outer side of the centrifugal filter 1 is equipped with a water inlet 13. The lower end of the centrifugal filter 1 is equipped with a sand discharge port 14. The other side of the lower end of the centrifugal filter 1 is equipped with a flushing valve 15.

[0019] Working principle: First, use bolts to fix the centrifugal filter 1 to the ground at the installation location by passing it through the holes on the surface of the base 704. Then, put the centrifugal filter 1 into the first support 702 and tighten the bolts to the first clamp 701 and the first support 702 to fix the centrifugal filter 1. Similarly, put the water inlet pipe 6 into the second support 11 and tighten the bolts to the second clamp 10 and the second support 11 to fix the water inlet pipe 6. Connect one end of the connecting pipe 12 to the water outlet 8 at the top of the centrifugal filter 1 and the other end of the connecting pipe 12 to the water inlet pipe 6. At the same time, insert the lower end of the disc filter 2 into the fixing ring 903 and use bolts to thread the fixing ring 903 and the disc filter 2 to fix the position between the fixing ring 903 and the disc filter 2. Connect the side interface of the disc filter 2 to the backwash valve 4 to assemble and fix the whole.

[0020] Personnel connect the water supply equipment to the inlet 13 using pipes. Water pumped into the inlet 13 enters the centrifugal filter 1. When the liquid enters the centrifugal filter 1, the centrifugal force generated by its high-speed rotation throws denser solid particles against the filter wall. This centrifugal force separates the solid particles from the liquid, allowing them to enter the lower end of the centrifugal filter 1. After the operation is complete, the flushing valve 15 connects to an external water pipe and the sand discharge port 14, achieving the same effect. This allows water to flush the sand in the lower end of the centrifugal filter 1 to the other end, resulting in the filtered and settled sand being discharged from the sand discharge port 14. The high-speed rotation generates clean water, which flows out from the outlet 8 and into the connecting pipe 12. The connecting pipe 12 then transports the water to the inlet pipe 6, which flows to the backwash valve 4. The water in the backwash valve 4 is transported into the disc filter 2. The stacked discs of the disc filter 2 form fine filtration channels. When the liquid flows through these channels, solid particles are trapped on the disc surface. During cleaning, the flushing valve 15 can be turned to make the water in the disc filter 2 flow backward due to resistance, which can wash away the impurities on the disc surface and discharge it from the drain outlet 5. The clean water is discharged out through the water pipe 3 for irrigation of the water-fertilizer field.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
