Description

Technical Field

[0001] The invention relates to the field of water treatment and water volume regulation, and in particular to a water distribution device for a dosing system. Background Art

[0002] In the dosing system of the current water treatment process, the same liquid medicine often needs to be transported to multiple dosing points. In the traditional design, in order to ensure the flow accuracy of each dosing point, it is generally adopted to configure a dosing pump and an independent pipeline for each dosing point. This decentralized dosing method not only leads to a significant increase in equipment investment costs (multiple pumps and supporting instruments are required), but also causes energy waste due to the parallel operation of multiple pumps. At the same time, the multi-pump system has the problems of complex pipeline layout and large maintenance workload, and the flow regulation of each branch needs to rely on the frequency adjustment of the pump body, with slow response speed and difficult coordinated control. Especially when dealing with flow fluctuation conditions, it is easy to produce ratio imbalance, affecting the water treatment effect. Although some improvement schemes try to distribute flow through mechanical weirs, there are still problems such as low adjustment accuracy, inability to remotely control, and easy clogging of the weir, which is difficult to meet the requirements of modern water treatment processes for precise and intelligent dosing of chemicals.

[0003] Therefore, in order to solve the above-mentioned problems, a water distribution device for a dosing system is specifically proposed. Summary of the invention

[0004] The present invention is aimed at the above-mentioned problems and specifically designs a water distribution device for a dosing system. The device can flexibly control the flow rate when dosing the dosing point with liquid medicine, thereby realizing free and sensitive flow distribution.

[0005] In order to achieve the above-mentioned purpose, the present invention provides a water distribution device for a dosing system, comprising: a total water distribution chamber, a distribution water chamber, a water outlet chamber and a water distribution weir, each water chamber is divided by a partition wall, a total feed pipe for liquid medicine is arranged at the front end of the total water distribution chamber, the distribution water chamber is arranged at the side of the total water distribution chamber and communicated with the total water distribution chamber, the water outlet chamber is arranged on the side of the distribution water chamber away from the total water distribution chamber, and the water outlet chamber is communicated with the distribution water chamber, the water distribution weir is arranged on the partition wall between the water outlet chamber and the distribution water chamber, the water distribution weir is provided with a weir for circulating liquid medicine, and a gate capable of adjusting the flow rate of liquid medicine is provided. Through the buffer volume design of the total water distribution chamber, the fluid kinetic energy of the feed pipe is effectively eliminated, the liquid medicine flow rate is stabilized, and a stable flow condition is created for subsequent precise distribution. The series structure of the distribution water chamber and the water outlet chamber cooperates with the adjustable water distribution weir, and multi-point dosing can be achieved with only a single dosing pump.

[0006] Furthermore, the water distribution weir also includes: a gate frame, a top plate, a gate plate and an electric transmission mechanism, the gate plate is a hollow structure, the top plate is arranged on the top of the water distribution weir, the gate frame is fixedly connected to the water distribution weir, the gate plate is a plate-shaped structure, and is slidably connected to the gate frame, the top plate is fixedly connected to the top of the water distribution weir, and the electric transmission mechanism is fixedly connected to the top plate and the transmission end is connected to the gate plate.

[0007] Through the above method, the gate plate has a hollow structure, which can reduce consumables.

[0011] Through the above method, the shaft sleeve can prevent the gate rod from being stuck during operation, thereby improving the stability of the device operation.

[0016] Furthermore, there are two main water distribution chambers, and different distribution water chambers are arranged on opposite sides of the two main water distribution chambers, and both sides of the water outlet chamber are located between the distribution water chambers on different main water distribution chambers.

[0017] Through the above method, the combination of water chambers can be flexibly selected to meet the mixing effect of various liquid medicines.

[0018] The present invention also discloses a method for using a water distribution device of a dosing system, comprising the following steps:

[0019] Step 1: Pass the liquid medicine into the main water distribution chamber through the main feed pipe;

[0020] Step 2: The liquid medicine is accumulated in the main water distribution chamber, and the large volume of the main water distribution chamber is used to reduce the larger flow rate of the liquid medicine when it is transported in the main feed pipe;

[0054] The difference between this embodiment and the above-mentioned embodiment is that, in this embodiment, the positions of the water chambers are arranged so as to meet the dosing requirements of the two kinds of liquid medicines.

[0058] like Figure 3 and Figure 6 As shown, a manual adjustment mechanism 43 is installed on the side of the vertical gate rod 4222, and a stepped bearing chamber 431 is installed on the side of the vertical gate rod 4222. Two gears 438 are arranged inside the stepped bearing chamber 431, one of which is installed on the vertical gate rod 4222, and the other gear 438 is connected to the end of the transmission shaft 432. The top end of the transmission shaft 432 passes through the top plate 424, and a hand wheel 433 is installed on the end extending out of the top plate 424. The outer sleeve of the transmission shaft 432 is provided with a shaft sleeve 425, and the shaft sleeve 425 is fixedly connected to the water distribution weir 4. By turning the hand wheel 433, the transmission shaft 432 can be driven to rotate, which drives the gear 438 to rotate.

[0060] Limit blocks 437 are installed at the bottom and top of the stepped bearing chamber 431. When the mode is switched, the limit blocks 437 can limit the adjustment height.

[0061] A guide block 439 is installed inside the shaft sleeve 425 . The guide block 439 is an annular structure and can play an auxiliary guiding role in the lifting and lowering of the transmission shaft 432 .

[0062] A method for using a water distribution device of a dosing system of the present invention comprises the following steps:

[0063] Step 1: Pass the liquid medicine into the main water distribution chamber 1 through the main feed pipe 11;

[0064] Step 2: The liquid medicine accumulates in the main water distribution chamber 1, and the large volume of the main water distribution chamber 1 is used to reduce the larger flow rate of the liquid medicine in the main feed pipe 11;

[0065] Step 3: The liquid medicine enters the water distribution chamber 2 through the water distribution pipe 21;

[0066] Step 4: Open the gate 42 on the water distribution weir 4, control the opening degree of the gate 42, and control the flow rate of the liquid medicine flowing into the water outlet chamber 3;

[0067] Step 5: The liquid medicine in the water outlet chamber 3 flows into the medicine adding point through the water outlet pipe 31 .

[0068] like Figure 1 and Figure 2 As shown, the water inflow from the main feed pipe 11 is recorded as Q, the width of the gate 42 is consistent with the width of the weir 41 and is recorded as B, the opening of the lower left gate 42 is recorded as b1, and the openings of the other three gates 42 in the counterclockwise direction are recorded as b2, b3 and b4 (i.e., the water flow width). Therefore, the flow rates of the outlet pipe 31 corresponding to the gates 42 are q1, q2, q3 and q4, and the flow rates can be calculated by the following formula:

[0069]

[0070] like Figure 1 and Figure 2 As shown, the opening of b1 is 50%, the opening of b2 is 50%, the opening of b3 is 0%, and the opening of b4 is 100%. Therefore, b1=0.5B, b2=0.5b, b3=0, b4=B. By calculating through the above formula, it can be obtained that q1=0.25Q, q2=0.25Q, q3=0, q4=0.5Q.

[0071] like Figure 4 and Figure 5 As shown, the flow rate of the upper total feed pipe 11 is recorded as Q1, and the flow rate required for each dosing point is recorded as q1, q2, q3, and q4; the flow rate of the lower total feed pipe 11 is recorded as Q2, the opening of the upper gate 42 from left to right is b1 and b2, and the opening of the lower gate 42 from left to right is b3 and b4. The openings of b1, b2, b3, and b4 are 40%, 60%, 100%, and 50%, respectively, and are calculated according to the following formula:

[0072]

[0073] Therefore, b1=0.4B, q1=0.4Q1; b2=0.6B, q2=0.6Q1; b3=B, q3=0.67Q2; b4=0.5B, q4=0.33Q2; therefore, the total flow rate of the left water outlet pipe 31=q1+q3=0.4Q1+0.67Q2; the total dosage of the right water outlet pipe 31=q2+q4=0.6Q1+0.33Q2.

[0074] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them. Although the present invention has been described in detail with reference to the above embodiments, a person skilled in the art should understand that the technical solutions described in the above embodiments can still be modified, or some of the technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
