The liquid outlet system 3 is used for discharging clear liquid, the clear liquid is discharged into the clear liquid chamber 21 from the cyclone 5, a clear liquid outlet is arranged in the clear liquid chamber 21 and is communicated with a liquid outlet pipeline, and the clear liquid is discharged through the liquid outlet pipeline. The liquid outlet pipe is provided with a first pressure sensor 32 for monitoring the pressure value of the clear liquid in the liquid outlet pipe in real time and feeding the pressure value back to the control terminal 34. A second pressure sensor 33 is arranged outside the clear liquid chamber 21, the second pressure sensor 33 is communicated with the clear liquid chamber 21 through a detection pipeline, so that the pressure value in the clear liquid chamber 21 is monitored in real time, the pressure value is fed back to the control terminal 34, and the control terminal 34 can monitor and display the pressure difference between the second pressure sensor 33 and the first pressure sensor 32. A positive pressure difference is ensured to ensure that the clear liquid is discharged from the clear liquid chamber 21.
It should be understood that when the pressure difference is equal or negative, the flow rate can be increased by the first pressure control valve in the liquid outlet system 3 to ensure that there is enough clear liquid and pressure in the clear liquid chamber 21 to achieve the clear liquid discharge condition.
In the present embodiment, each of the cyclones 5 includes: an outer tube 51, which is arranged in the material distribution chamber 22 of the accommodating cavity 2, has a closed top end and a bottom end communicated with the impurity chamber 23 of the accommodating cavity 2; an inner tube 52 coaxially arranged in the outer tube 51, wherein the top end of the inner tube is communicated with the clear liquid chamber 21 of the accommodating cavity 2, the bottom end of the inner tube is closed, a plurality of water inlet holes 57 are formed in the inner tube, and the water inlet holes 57 are communicated with the inner tube 52 and the outer tube 51; (ii) a The first end of the branch pipe 6 is communicated with the outer pipe 51, the branch pipe 6 is vertically tangent to the outer pipe 51, and the second end of the branch pipe 6 is communicated with a liquid inlet pipeline of the liquid inlet system 1.
The cyclone flows into the outer tube 51, the foreign substances are moved toward the inner wall surface of the outer tube 51 by centrifugal force by rotation in the cyclone 5, and the top end of the outer tube 51 is closed by water pressure, and thus, the foreign substances can be brought into the foreign substance chamber 23 only by moving toward the bottom end, and the clear liquid in the middle of the cyclone flow can be introduced into the inner tube 52 by the water inlet 57 of the outer tube 51 communicating with the inner tube 52, so that the clear liquid is introduced into the clear liquid chamber 21 from the top end of the inner tube 52.
The bottom end of the outer pipe 51 is communicated with the impurity chamber 23 to discharge impurities (feed liquid with insoluble substances), and the top end of the outer pipe 51 is hermetically connected with the isolation plate 24 to realize the fixation of each outer pipe 51, and an interval is arranged between the inner pipe 52 and the outer pipe 51 for the water flow to pass through and rotate between the inner wall of the outer pipe 51 and the outer wall of the inner pipe 52, so that the feed liquid is rotated in the outer pipe 51 to separate solid from liquid in the feed liquid. In order to ensure that the feed liquid can rotate around the inner pipe 52 quickly after entering the outer pipe 51, the axial direction of the branch pipe 6 is perpendicular to the outer pipe 51, and the inner pipe 52 is arranged to ensure that the feed liquid rotates around the shaft after entering the outer pipe 51. The rotational speed of feed liquid is different in making outer tube 51 to different velocity of flow to providing different centrifugal force to impurity, realizing the degree difference to the solid-liquid separation of feed liquid, the rotational speed is too fast can make too much clear liquid enter into impurity chamber 23, and the rotational speed is too slow can make the centrifugal force of impurity little, and the solid-liquid separation effect is poor, gets into more undissolved substance in the clear liquid chamber 21, makes quality of water unqualified.
In an optional embodiment, the bottom end of the inner pipe 52 is provided with an inverted conical cap 55, and each water inlet 57 is formed in the conical cap 55, so that the clear liquid can enter the inner pipe, it should be understood that the diameter of the arranged conical cap 55 is gradually reduced, so that the entering clear liquid is gradually close to the central axis of the rotational flow, and the conical cap 55 is arranged at the bottom end of the inner pipe 52, so that the rotational flow is guaranteed to have enough time for throwing impurities to the inner wall surface of the outer pipe 51, and the solid-liquid separation effect is improved.
In an alternative embodiment, referring to fig. 4, the bottom end of the inner tube 52 is provided with an inverted conical cap 55, the bottom end of the conical cap 55 is open, a blocking plate 58 is arranged inside the conical cap 55, the blocking plate 58 can block the opening at the bottom end of the conical cap 55, the blocking plate 58 is coaxially connected inside the opening of the conical cap 55 through a spring 59, and the blocking plate 58 is pulled by the spring 59 to seal and block the opening. It can be known that, when the water inlet 57 on the inner pipe 52 is blocked or the flow rate of the feed liquid is increased, the pressure of the feed liquid in the outer pipe 51 is increased, and when the pressure of the outer pipe 51 acts on the resistance plate 58 and the pressure value is greater than the pulling force value of the spring 59, the spring 59 is pushed open, so that the clear liquid in the middle of the rotational flow enters the inner pipe 52 from the opening. The advantage is that the pressure increase of the outer tube 51 will flush the blockage of the inlet 57, and the inlet of the inner tube 52 through the opening increases the flow of the discharged clear liquid and also plays a role in releasing the pressure in the outer tube 51.
In the present embodiment, the branch pipes 6 of each cyclone 5 are connected in parallel to the liquid inlet pipeline, and it should be understood that, under the condition of sufficient liquid flow supply, the flow rate and flow velocity of the liquid in each branch pipe 6 should be consistent, so that the rotation speed of the liquid in each outer pipe 51 is consistent, and the liquid-solid separation effect of the liquid in each cyclone 5 is ensured to be consistent.
Referring to fig. 3, the outer wall of the inner pipe 52 is provided with a first thread groove 54 that is outwardly screwed towards the bottom end thereof, so that after the feed liquid enters the outer pipe 51, the first thread groove 54 plays a certain guiding role in the water flow, and the efficiency of the water flow rotation is further improved.
By the same token, it can be understood that: the inner wall of the outer tube 51 is provided with a second thread groove 53 which is internally screwed towards the bottom end of the outer tube, the second thread groove 53 is provided with at most three rings, and the thread pitch of the second thread groove 53 towards the bottom end of the outer tube 51 is gradually increased. Each thread groove is a spiral groove towards the bottom end, so that the initial state of the feed liquid in the inlet pipe moves towards the bottom end, impurities on the inner wall of the outer pipe 53 can be washed downwards, and the separated impurities enter the impurity chamber 23 under the action of the continuous feed liquid. Thereby improving the effect of solid-liquid separation, leading the feed liquid to move downwards in a rotating way, leading the clear liquid to move upwards from the inner pipe 52 in the rotating process and enter the clear liquid chamber, and obtaining purer clear liquid.
In an alternative embodiment, the beginning of each thread groove is located opposite to the branch pipe, so that the feed liquid is guided by the thread grooves after entering the cyclone 2. The downward interval of each thread groove increases gradually in proper order, plays the effect to the high-efficient rotatory direction of rivers.
In an alternative embodiment, the bottom end of each outer tube 51 is a tapered tube 56, and the inner surface of the outer tube 51 has an inclination angle of not more than 10 degrees with respect to the axial line, so that the inner diameter of the outer tube 51 gradually increases from top to bottom. Its purpose is that the lower part of the inner diameter of the outer tube 51 is larger than the upper part, which can reduce the adhesion of the impurities on the inner wall of the outer tube 51, and provide a downward force, which is beneficial to the downward movement of the impurities and the entry of the impurities into the impurity chamber 23. The section is the bottom end of the conical pipe 56, so that the speed of the feed liquid entering the impurity chamber 23 is reduced, the rotating time of the feed liquid in the outer pipe 51 is further prolonged, and the solid-liquid separation effect is improved.
A plurality of water inlet holes 57 opened on each inner tube 52 are arranged at the middle part and the bottom part of the inner tube 52, each water inlet hole 57 is used for allowing the separated clear liquid entering the outer tube 51 to enter the inner tube 52, and the clear liquid enters the clear liquid chamber 21 under the continuous supply of the clear liquid. It should be understood that, when the feed liquid enters the outer tube 51 initially, the solid-liquid separation effect is not good, and under the effect of the multiple rotation of the feed liquid, the impurities in the feed liquid are thrown to the inner wall of the outer tube 51 under the effect of the centrifugal force, so that the feed liquid gradually becomes pure, enters the inner tube 52 through the water inlet 57 at the upper part, the middle part and the lower part of the inner tube 52, moves towards the upper clear liquid chamber 21 under the effect of the water pressure, and is discharged out of the clear liquid chamber 21.
In this embodiment, each of the pipelines is provided with a manual control valve to manually control the opening and closing of each pipeline.
The solid-liquid separator further comprises a water quality online detection system, wherein the water quality online detection system is arranged at the clear liquid outlet and the impurity chamber 23 of the accommodating cavity 2 and is used for monitoring the water quality of the clear liquid outlet and the water quality in the impurity chamber 23 in real time;
the online monitoring system is electrically connected with the liquid inlet system 1 and the liquid outlet system 3, and the liquid inlet system 1 and the liquid outlet system 3 are regulated and controlled through the monitored water quality, so that the water quality of the discharged clear liquid is ensured to meet the standard.
The on-line measuring system monitoring is used for carrying out real-time supervision to the quality of water of exhaust clear liquid and impurity, mainly makes the clear liquid meet the standard, can also be through the monitoring to discharge water quality, the operating condition of each swirler 5 of real-time control for when discharge water quality meets the standard in through swirler 5, can also improve work efficiency to and save time and cost.
As will be appreciated by those skilled in the art: the water quality criteria include temperature, residual chlorine, conductivity, PH and total dissolved solids, and in this example the water quality in the supernatant is monitored by conductivity, it being understood that the lower the conductivity the purer the water quality.
In a second aspect, the present application provides a method of controlling a solid-liquid separator, comprising the steps of: the flow and the flow velocity of the feed liquid are controlled by a liquid inlet system, so that the feed liquid enters each cyclone; controlling the discharge of the clear liquid through a liquid outlet system; the quality of water in the impurity chamber and the discharged clear liquid is monitored in real time through an online detection system, and liquid inlet of the feed liquid, discharge of impurities and discharge of the clear liquid are controlled according to the detected quality of water.
When the on-line monitoring system monitors that:
in the first case, when the water quality in the impurity chamber 23 exceeds a first preset standard value and the water quality in the clear liquid discharge port does not exceed a second preset standard value, the flow rate of the discharged liquid is controlled or increased. Specifically, it may be that the insoluble substance in impurity chamber 23 is more to lead to the quality of water in impurity chamber 23 to exceed first preset standard value, but do not influence the quality of water of exhaust clear liquid, consequently, steerable drain discharge feed liquid, perhaps increase the flow of exhaust feed liquid, thereby make the quality of water in impurity chamber 23 be less than first preset standard value, avoided the more quality of water that influences exhaust clear liquid of impurity in impurity chamber 23. Additionally, it should be understood that the first predetermined scalar value is greater than the second predetermined scalar value.
In the second case, when the water quality in the impurity chamber 23 exceeds the first preset standard value and the water quality in the clear liquid outlet exceeds the second preset standard value, the flow rate of the discharged liquid is controlled or increased by the drain outlet, and the flow rate of the increased liquid in the liquid inlet system 1 is controlled. Specifically, it may be that the impurity in the impurity chamber 23 is more, and the content of the insoluble substance in the discharged clear liquid exceeds the second preset standard value, so that the water quality in the impurity chamber 23 is lower than the first preset standard value by discharging the impurity liquid or increasing the discharged flow, and the speed of the swirling flow is accelerated by increasing the flow of the liquid inlet of the liquid, thereby improving the purity of the clear liquid.

In an alternative embodiment, when in the third situation, the flow rate of the feed liquid may be controlled by gradually increasing the flow rate V1 to the flow rate Vn (n is a natural number greater than 1) until the discharged clear liquid is lower than the second predetermined standard value, and correspondingly maintaining the flow rate of the feed liquid.
In an alternative embodiment, in the third case, the flow rate of the feed liquid is controlled to gradually decrease from the flow rate Vn to the flow rate V1 until the discharged clear liquid is lower than the second predetermined standard value, and the flow rate of the feed liquid is correspondingly maintained.
