As shown in fig. 1, the settling device 1 and the filtering device 2 are connected in series in sequence to form a group of treatment units so as to form a separation treatment for solid impurities in water. Wherein, the sedimentation device 1 adopts a cyclone separation structure, water supplied by the water supply source 4 enters the sedimentation device 1 from the water inlet pipe 111 of the sedimentation device 1, solid impurities in the water are partially separated and settled to the bottom of the chamber 11 in the sedimentation device 1, and the treated water is discharged through the water outlet pipe 101 at the top of the sedimentation device 1. The filter device 2 adopts a backwashing filter structure, water discharged by the water outlet pipe 101 enters the inner cavity 20 of the filter device 2 through the water inlet pipeline 21 of the filter device 2, is filtered by the filter body 3 arranged in the inner cavity 20, and is discharged to the main water outlet pipeline 43 of the water and fertilizer drip irrigation water treatment system through the water outlet pipeline 22 of the filter device 2; the solid impurities flushed from the filter body 3 by backwashing are discharged through a sewage discharge pipeline 23 on the filter device 2.

In order to improve the operation and maintenance performance of the system, in the embodiment, the water and fertilizer drip irrigation water treatment system comprises two groups of treatment units which are arranged in parallel; in this way, not only can one set be shut down for maintenance, but also when two sets are used together, the two filter devices 2 can be alternately backwashed, thereby improving a good water pressure condition for backwashing of the filter devices 2.

As shown in fig. 1, the water inlet pipes 111 of the two settling devices 1 are respectively provided with a first settling valve 403 and a second settling valve 404, and the water outlet pipes 22 of the two filtering devices 2 are respectively provided with a first filtering valve 405 and a second filtering valve 406 for closing a certain group of processing units. In addition, a main sewage discharge pipeline 44 is arranged in the system, and the floating object discharge pipe 102 of the sedimentation device 1 and the sewage discharge pipeline 23 of the filtering device 2 are communicated with the main sewage discharge pipeline 44 in a confluence manner and are discharged into a sewage discharge pool 45 through the main sewage discharge pipeline 44.

An exemplary structure of the settling device 1 of the present embodiment is shown in fig. 2, and mainly includes a housing integrally constructed by a top cover plate 100, a water inlet pipe 111 and a bottom cover plate 120, and a water inlet pipe 111 and a water outlet pipe 101 provided on the housing.

The sidewall 110 is cylindrical, the sidewall 110 covers the top of the sidewall 110, and the bottom cover plate 120 covers the bottom of the sidewall 110. The whole shell is enclosed to form a cavity 11 for separating water, and an inverted conical guide cavity 12 is enclosed by a bottom closing plate 120 below the cavity 11. The bottom of the outlet chamber 12 is connected with an on-off discharge pipe 131.

As shown in fig. 3, the water inlet pipe 111 is disposed at the middle upper portion of the sidewall 110 and is disposed along a tangential line of the circumferential surface of the sidewall 110, and when water is supplied to the water inlet pipe 111 by an external water supply unit at a certain water pressure, the water enters the chamber 11 through the water inlet pipe 111. Due to the tangential direction of the water inlet pipe 111, the water to be separated is introduced into the chamber 11 along the tangential direction of the inner wall of the chamber 11, a swirling water flow is formed, and the solid impurities spirally slide down to the bottom of the chamber 11 along the inner wall of the chamber 11 due to the action of the water flow. When the chamber 11 is filled with water, the water from which the solid impurities have been removed flows out of the device through the water outlet pipe 101 of the top cover plate 100 for drip irrigation.

As shown in fig. 3, a storage bin 130 is provided between the discharge chamber 12 and the discharge pipe 131, a through hole 133 is provided between the storage chamber 13 and the discharge chamber 12 in the storage bin 130, and the radial dimension of the through hole 133 is smaller than the radial dimension of the maximum position of the storage chamber 13. Preferably, the accumulation chamber 13 is in the shape of an inverted cone, the through hole 133 is opened at the center of the top of the accumulation chamber 13, and the bottom of the accumulation chamber 13 is communicated with the discharge pipe 131. The storage bin 130 can temporarily store the sunk solid impurities, and the separated solid impurities are reduced to return to the middle part of the chamber 11 again due to the vortex flow of the water; on the other hand, the inverted conical accumulation cavity 13 is adopted, so that the solid impurities entering the accumulation cavity 13 are more difficult to return to the chamber 11, and the accumulation effect of the accumulation cavity 13 is improved.

To achieve the regular discharge of the solid impurities in the accumulation chamber 13, a first valve 132 may be installed on the discharge pipe 131. For example, the first valve 132 may be a manual butterfly valve, a pneumatic butterfly valve, or the like. In this way, the solid impurities in the reservoir 13 can be periodically discharged to the outside of the apparatus by the water pressure in the chamber 11 by periodically opening the first valve 132.

As shown in fig. 2 in conjunction with fig. 4, outlet pipe 101 is disposed at the center of top cover plate 100, and the bottom end of outlet pipe 101 protrudes into chamber 11 for a certain length. The pipe diameter of the water outlet pipe 101 can be consistent with that of the water inlet pipe 111. The water outlet pipe 101 is arranged at the center of the top cover plate 100, so that solid impurities which are spirally slipped near the inner wall of the cavity 11 in the cavity 11 are far away, the solid impurities which can float in the water can also surround the periphery of the bottom end of the water outlet pipe 101 and stay in the floater collecting area 115, and the possibility that the solid impurities enter the water outlet pipe 101 can be greatly reduced.

In addition, an openable and closable floater discharging pipe 102 may be further communicatively provided on the top cover plate 100, and a second valve 104 may be installed on the floater discharging pipe 102 to control the opening and closing of the floater discharging pipe 102. By providing the float discharge pipe 102 on the top cover 100, the floating solid impurities collected in the float collecting area 115 can be periodically discharged to the outside of the apparatus by periodically opening the float discharge pipe 102.

In order to facilitate the collection of the solid impurities floating in the float collecting area 115 into the float discharging pipe 102, the connecting part of the float discharging pipe 102 and the top cover plate 100 is configured as a trumpet-shaped inlet 103, and the solid impurities floating in the float collecting area 115 on the top of the cavity 11 are collected into the float discharging pipe 102 through the inlet 103.

As shown in fig. 3 and 4, a spiral downward flow guide plate 112 is arranged on the inner wall of the chamber 11 between the inlet of the water inlet pipe 111 and the outlet chamber 12, and a flow guide channel 114 capable of guiding the downward flow of the sinking solid impurities is formed between the adjacent flow guide plates 112. Therefore, the falling solid impurities can slide to the bottom of the cavity 11 along the flow guide channel 114, and the possibility that the solid impurities flow into the water outlet pipe 101 along with water flow is further reduced, so that the separation performance of the device is improved.

Meanwhile, the inner diameter of the flow guide plate 112 is larger than the outer diameter of the outlet pipe 101 when viewed from the top of the top cover plate 100 toward the bottom cover plate 120. Thus, a certain distance is reserved between the inner edge of the guide plate 112 and the outer peripheral surface of the water outlet pipe 101, a channel for floating solid impurities to be separated from the guide channel 114 and rise to the floating object collecting area 115 can be formed, and a good separation movement effect in the cavity 11 is favorably formed.

Since there is a starting end of the deflector 112 at the inlet of the water inlet pipe 111, in order to reduce the front impact of the stone on the deflector 112, the end portion of the deflector 112 adjacent to the inlet of the water inlet pipe 111 is constructed as a water-receiving section 113, the width of the water-receiving section 113 is gradually narrowed toward the direction of the water inlet pipe 111, so that the two sides of the water-receiving section 113 are converged onto the inner wall of the chamber 11. The tip that will be located the guide plate 112 of oral siphon 111 entrance sets up to meeting water section 113, can prevent the positive circumstances that strikes guide plate 112 of debris such as the stone that gets into by oral siphon 111 to can reduce guide plate 112's damage condition, do benefit to hoisting device's life.
