Description

Technical Field

[0001] The invention relates to the technical field of sewage sampling, in particular to a water separation device for sewage detection. Background Art

[0002] In the process of sewage treatment in sewage treatment plants, it is necessary to frequently take samples of treated water to analyze the sewage treatment effect and the components in the sewage (such as ammonia nitrogen, nitrate nitrogen, and orthophosphate detection) in order to formulate effective treatment measures. Therefore, the sampling process is very complicated and the labor intensity of sampling for staff is relatively high.

[0003] Especially for different test items, it is necessary to prepare solution samples of equal doses for comparison. Generally, a certain amount of water is divided into multiple equal parts, or multiple cups of equal sewage are taken for comparative tests.

[0004] This makes the sampling process more frequent and cumbersome. Therefore, it is necessary to design a device that can realize timed automatic water extraction and equal water distribution, which will significantly reduce the labor time. Moreover, since sewage is rich in algae and microorganisms, even if the sampling process has been filtered, after long-term circulation and retention in the water distribution device, it will cause the growth of attachments in the water distribution device, affecting the detection structure, resulting in the need for manual regular cleaning of the water distribution device. Therefore, if a self-cleaning structural function can be designed, the frequency of manual operations will be reduced and the automatic operation time will be increased. Summary of the invention

[0005] In order to overcome the above-mentioned deficiencies of the prior art, the present invention provides a water separation device for sewage detection.

[0006] The technical solution of the present invention is as follows: a water distribution device for sewage detection, comprising a water distribution cup, a water inlet pipe, a water extraction pipe, a drainage pipe, a PLC controller, a delivery pump body, and an extraction pump body. One end of the water inlet pipe is connected to the delivery pump body, and the other end extends to the bottom of the water distribution cup for communication. The drainage pipe is connected to the water distribution cup and is arranged vertically above the water inlet pipe at intervals. The water extraction pipe comprises a water extraction port extending into the water distribution cup. The vertical height position of the water extraction port is lower than the drainage pipe, and the vertical spacing between the water extraction port and the drainage pipe is set according to the required capacity of one water distribution.

[0007] The extraction pump body is connected to the water extraction pipe, and the PLC controller is connected to the delivery pump body and the extraction pump body signal to perform timing opening and closing control.

[0008] By adopting the above-mentioned technical problem, in order to automatically distribute equal amounts of water samples, the water distribution cup of the present application is provided with a bottom water inlet pipe, a drain pipe at the highest point, and a pumping pipe therebetween. With this arrangement, even if the water inflow is too large at one time, the water level in the water distribution cup will automatically be discharged when it reaches the drain pipe at the highest point. Each time the pump body is replenished with water, it can only reach the liquid level at the drain pipe position of the water distribution cup.

[0009] The vertical height of the water suction port of the suction pipe is lower than that of the drainage pipe, and the vertical distance between the water suction port and the drainage pipe is set according to the capacity required for one water distribution. The maximum capacity of the water suction pipe to be extracted at one time is multiplied by the bottom area of ​​the water distribution cup by the vertical distance to obtain the capacity of equal water distribution. When the liquid level drops below the water suction port, even if the extraction pump body continues to operate, it is impossible to extract excessive water samples.

[0010] In addition, the PLC controller is connected with the delivery pump body and the extraction pump body signal to perform timing opening and closing control and alternate operation. It realizes the functions of automatic water replenishment, automatic drainage control of the highest liquid level, and automatic pumping of equal amounts of water samples. There is no need for a high-precision pump body to control water inlet, drainage, and pumping. Even if it is over-operated, it can only obtain the water sample capacity obtained according to the position setting of the drainage pipe and the water pumping pipe.

[0011] The utility model is further configured as follows: the drainage pipe includes an inlet end, an arched portion and a discharge end, the inlet end is connected to the water dividing cup and is arranged at an interval vertically above the water inlet pipe, the vertical height of the arched portion is higher than the vertical position of the inlet end and lower than the highest water level of the water dividing cup capacity, and the vertical height of the discharge end is lower than the vertical position of the inlet end.

[0012] By adopting the above technical solution and setting the drainage pipe structure, when the liquid level in the water-dividing cup reaches the height of the arched part, the drainage pipe generates a siphon phenomenon, and discharges the overflow in the water-dividing cup with a certain suction force. The advantage of such a setting is that the suction force generated by the siphon accelerates the water flow when it is discharged, generates the vortex effect of the flush toilet, and takes away the attachments on the inner wall of the water-dividing cup. That is, the siphon effect of the drainage pipe is used to achieve the cleaning effect in the water-dividing pipe, prolong the operation cycle of the water-dividing cup, and reduce the frequency of manual maintenance.

[0013] The utility model is further configured as follows: the water-dividing device comprises a cleaning piece arranged in the water-dividing cup, the cleaning piece comprises an upper floating ring made of a floating material, a lower sinking ring sunk below the water-dividing cup, and a pull rope connecting the two; the upper floating ring floats and moves up and down with the liquid level in the water-dividing cup, and pulls the lower sinking ring to move in a vertical direction; the diameters of the upper floating ring and the lower sinking ring are both smaller than the water-dividing cup, and the outer circumferences are both surrounded by a plurality of bristles extending toward the inner wall of the water-dividing cup.

[0014] By adopting the above technical scheme, the cleaning part is set up to utilize the characteristics of the liquid level rising and falling of the water dividing cup of the present application. The buoyancy of the upper floating ring is greater than the gravity of itself and the sinking ring, and the sinking ring is made of non-buoyancy material and is always sunk in the water dividing cup. The two are connected and are both provided with a circle of bristles, which rise and fall with the rise and fall of the liquid level, so that the bristles scrape the inner wall of the water dividing cup, clean up the attachments, and extend the operation cycle.

[0015] The utility model is further configured as follows: the water dividing cup comprises a cylinder, an upper end cover and a lower end cover; the cylinder is vertically arranged; the upper and lower cylinder openings are respectively connected with the upper end cover and the lower end cover by sealing threads; the upper end cover is provided with a hole for the water pump to pass through.

[0016] By adopting the above technical solution, the water separation cup is set to be cylindrical, which is easy to disassemble and clean, and avoids residual attachments at the bottom of the cup.

[0017] The utility model is further configured as follows: the cylinder is made of a transparent material, and a hook or an insert is arranged on the outer peripheral surface of the cylinder.

[0018] By adopting the above technical solution, the transparent material makes it easy to observe the growth of attachments in the water separation cup, and the provided hooks and sockets facilitate convenient and detachable connection with the chassis.

[0019] A further configuration of the utility model is that the delivery pump is a diaphragm pump.

[0020] Further configuration of the utility model: the cylinder is provided with an elongated circular groove penetrating into the cylinder along the vertical direction, the water distribution device also includes an adjusting plate, the area of ​​the adjusting plate is larger than the area of ​​the elongated circular groove, and the adjusting plate is arranged in the cylinder, fitting with the inner wall of the cylinder and covering the elongated circular groove, the end surface of the adjusting plate facing the inside of the cylinder is provided with a sealing ring surrounding the elongated circular groove, the adjusting plate is provided with a threaded column passing through the elongated circular groove, the water distribution cup and the outside of the cylinder are provided with nuts that threadably cooperate with the threaded column, the nut is tightened to drive the adjusting plate to fit tightly against the inside of the cylinder, the drain pipe is sleeved with the threaded column, and the threaded column is provided with a drainage hole that penetrates from the cylinder to the drain pipe.

[0021] By adopting the above technical scheme, through the setting of the adjustment plate structure, the force when the nut is tightened is utilized to make the adjustment plate close to the inner wall of the cylinder, and the sealing ring is provided to prevent the water sample in the water distribution cup from flowing out of the long circular groove. In addition, the characteristic that the area of ​​the adjustment plate is larger than the long circular groove realizes the function of adjusting the vertical height position of the drain pipe, that is, realizing the adjustment of the capacity of the water sample extracted by the suction pipe at one time.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows: the water-dividing cup structure designed in the present application realizes the functions of automatic water replenishment, automatic drainage to control the highest liquid level, and automatic pumping of equal amounts of water samples, without the need for a high-precision pump to control water inlet, drainage, and pumping. Even if it is over-operated, it can only obtain the water sample capacity obtained according to the position setting of the drainage pipe and the water pumping pipe, thus completing the automatic sampling and water-dividing function. At the same time, the drainage pipe siphon mechanism and the cleaning part structure are used to automatically clean the attachments in the water-dividing cup, improve the quality of the water sample, extend the operation cycle of the water-dividing cup, and reduce the frequency of manual maintenance and cleaning.

[0029] In order to make the technical solution and advantages of the present application clearer, the technical solution of the present application will be further described in detail in detail and in detail in conjunction with the accompanying drawings. It can be understood that the specific embodiments described here are only partial embodiments of the present application, which are only used to explain the present application, not to limit the present application.

[0030] The present invention is described in detail below in conjunction with the accompanying drawings. Figure 1-4 As shown,

[0031] A water distribution device for sewage detection, comprising a water distribution cup 1, a water inlet pipe 2, a water extraction pipe 3, a drainage pipe 4, a PLC controller, a delivery pump body, and an extraction pump body, wherein one end of the water inlet pipe 2 is connected to the delivery pump body, and the other end extends to the bottom of the water distribution cup 1 for communication, the drainage pipe 4 is connected to the water distribution cup 1, and is arranged vertically above the water inlet pipe 2 at intervals, the water extraction pipe 3 comprises a water extraction port 31 extending into the water distribution cup 1, the vertical height position of the water extraction port 31 is lower than the drainage pipe 4, and the vertical spacing between the water extraction port 31 and the drainage pipe 4 is set according to the required capacity of one water distribution;

[0032] The extraction pump body is communicated with the water extraction pipe 3, and the PLC controller is connected with the delivery pump body and the extraction pump body signal to perform timing opening and closing control.

[0033] In order to automatically distribute equal amounts of water samples, the water distribution cup 1 of the present application is provided with a bottom water inlet pipe 2, a drain pipe 4 at the highest point, and a pumping pipe 3 therebetween. With this arrangement, even if the water inflow is too large at one time, the water level in the water distribution cup 1 will automatically be discharged when it reaches the drain pipe 4 at the highest point. Each time the pump body is replenished with water, it can only reach the liquid level at the drain pipe 4 of the water distribution cup 1.

[0034] The vertical height position of the water suction port 31 of the suction pipe 3 is lower than that of the drainage pipe 4, and the vertical distance between the water suction port 31 and the drainage pipe 4 is set according to the capacity required for one water distribution. The maximum capacity of the water suction pipe 3 to be extracted at one time is obtained by multiplying the bottom area of ​​the water distribution cup 1 by the vertical distance, that is, the capacity for equal water distribution. When the liquid level drops below the water suction port 31, even if the extraction pump body continues to operate, it is impossible to extract excessive water samples.

[0035] In addition, the PLC controller is connected with the delivery pump body and the extraction pump body signal to perform timing opening and closing control and alternate operation. It realizes the functions of automatic water replenishment, automatic drainage control of the highest liquid level, and automatic pumping of equal amounts of water samples. There is no need for a high-precision pump body to control water inlet, drainage, and pumping. Even if it is over-operated, it can only obtain the water sample capacity obtained according to the position setting of the drainage pipe 4 and the pumping pipe 3.

[0036] The drain pipe 4 includes an inlet end 43, an arched portion 42 and a drain end 41. The inlet end 43 is connected to the water dividing cup 1 and is arranged vertically above the water inlet pipe 2 at an interval. The vertical height of the arched portion 42 is higher than the vertical position of the inlet end 43 and lower than the highest water level of the water dividing cup 1. The vertical height of the drain end 41 is lower than the vertical position of the inlet end 43.

[0037] As the instruction manual Figure 4 As shown, through the arrangement of the drainage pipe 4 structure, when the liquid level in the water-dividing cup 1 reaches the height position of the arched portion 42, the drainage pipe 4 generates a siphon phenomenon, and discharges the overflow in the water-dividing cup 1 with a certain suction force. The advantage of such an arrangement is that the suction force generated by the siphon accelerates the water flow when it is discharged, generates a vortex effect of a flush toilet, and takes away the attachments on the inner wall of the water-dividing cup 1. That is, the siphon effect of the drainage pipe 4 is used to achieve the cleaning effect in the water-dividing pipe, prolong the operation cycle of the water-dividing cup 1, and reduce the frequency of manual maintenance.

[0038] The water distribution device includes a cleaning piece arranged in the water distribution cup 1, which includes an upper floating ring 51 made of a floating material, a lower sinking ring 52 sunk below the water distribution cup 1, and a pull rope 53 connecting the two. The upper floating ring 51 floats and moves up and down with the liquid level in the water distribution cup 1, and pulls the lower sinking ring 52 to move in the vertical direction. The diameters of the upper floating ring 51 and the lower sinking ring 52 are both smaller than the water distribution cup 1, and the outer peripheral surfaces are surrounded by a plurality of bristles 54 extending toward the inner wall of the water distribution cup 1.

[0039] The cleaning piece is arranged to utilize the characteristics of the liquid level rise and fall of the water dividing cup 1 of the present application. The buoyancy of the upper floating ring 51 is greater than the gravity of itself and the sinking ring 52, and the sinking ring 52 is made of non-buoyancy material and is always sunk in the water dividing cup 1. The two are connected and are both provided with a circle of bristles 54, which move up and down with the rise and fall of the liquid level, so that the bristles 54 scrape the inner wall of the water dividing cup 1, clean up the attachments, and extend the operation cycle.

[0040] The water distributing cup 1 comprises a cylinder 11, an upper end cover 12 and a lower end cover 13. The cylinder 11 is vertically arranged, and the upper and lower cylinder openings are respectively connected with the upper end cover 12 and the lower end cover 13 by sealing threads. The upper end cover 12 is provided with a hole for the water pumping pipe 3 to pass through.

[0041] The water separator cup 1 is set to be cylindrical, which is convenient for disassembly and cleaning to avoid residual attachments at the bottom of the cup.

[0042] The cylinder 11 is made of a transparent material, and a hook or plug 14 is arranged on the outer circumference of the cylinder 11 .

[0043] The transparent material makes it easy to observe the growth of attachments in the water-dividing cup 1, and the provided hooks and sockets facilitate convenient detachable connection with the chassis.

[0044] The delivery pump is a diaphragm pump.

[0045] The cylinder 11 is provided with an oblong groove 15 penetrating into the cylinder 11 along the vertical direction. The water distribution device also includes an adjusting plate 7. The adjusting plate 7 has an area larger than that of the oblong groove 15 and is arranged in the cylinder 11 to fit with the inner wall of the cylinder 11 and cover the oblong groove 15. The end surface of the adjusting plate 7 facing the inside of the cylinder 11 is provided with a sealing ring surrounding the oblong groove 15. The adjusting plate 7 is provided with a threaded column 71 passing through the oblong groove 15. The water distribution cup 1 and the cylinder 11 are provided with a nut 73 threadably matched with the threaded column 71 outside. The nut 73 is tightened to drive the adjusting plate 7 to fit tightly against the inside of the cylinder 11. The drain pipe 4 is sleeved with the threaded column 71. The threaded column 71 is provided with a drain hole 72 penetrating from the inside of the cylinder 11 to the drain pipe 4.

[0046] By setting the adjustment plate 7 structure and utilizing the force when the nut 73 is tightened, the adjustment plate 7 is pressed tightly against the inner wall of the cylinder 11, and the sealing ring is set to prevent the water sample in the water distribution cup 1 from flowing out of the oblong groove 15. In addition, the area of ​​the adjustment plate 7 is larger than the oblong groove 15, so the function of adjusting the vertical height position of the drain pipe 4 is achieved, that is, the capacity of the water sample extracted by the suction pipe 3 at one time is adjusted.

[0047] The water-dividing cup 1 structure designed in this application realizes the functions of automatic water replenishment, automatic drainage to control the highest liquid level, and automatic pumping of equal amounts of water samples. There is no need for a high-precision pump to control water inlet, drainage, and pumping. Even if it is over-operated, it can only obtain the water sample volume obtained according to the position setting of the drainage pipe 4 and the pumping pipe 3, thus completing the automatic sampling and water-dividing function. At the same time, the siphon mechanism of the drainage pipe 4 and the cleaning part structure are used to automatically clean the attachments in the water-dividing cup 1, improve the quality of the water sample, extend the operation cycle of the water-dividing cup 1, and reduce the frequency of manual maintenance and cleaning.
