Description

Technical Field

[0001] The utility model relates to the field of flocculant devices, in particular to a polyacrylamide flocculant metering adder. Background Technique

[0002] The polyacrylamide flocculant metering adder optimizes the water treatment effect by accurately controlling the dosage of the medicament. It can operate automatically, reduce the waste of the medicament, improve the clarity of the water quality, and reduce the content of suspended solids and organic substances. It is widely used in the treatment of sewage, drinking water and industrial wastewater, with strong adaptability and meeting different water quality requirements.

[0003] At present, the polyacrylamide flocculant adding devices on the market generally rely on manual operation by workers to add the medicament. This method undoubtedly increases the work burden of the workers and reduces the work efficiency. In addition, such devices are often limited to preparing flocculant solutions of a single concentration. When facing diverse sewage treatment requirements, such as when it is necessary to treat two different types of sewage, a large amount of time must be spent reconfiguring the solution, which undoubtedly delays the overall process of sewage treatment and affects the treatment efficiency and flexibility.

[0004] Therefore, in view of the situation that the above-mentioned polyacrylamide flocculant adding device cannot perform automatic feeding and cannot flexibly adjust the solution concentration, a polyacrylamide flocculant metering adder can be designed. By setting two stirring tanks of different concentration types, different concentrations of solutions can be prepared while automatically feeding the polyacrylamide flocculant, so as to facilitate the treatment of different sewage. Content of the Utility Model

[0005] In order to overcome the problems that the polyacrylamide flocculant adding device cannot perform automatic feeding and cannot flexibly adjust the solution concentration.

[0006] The technical solution of the utility model is as follows: a polyacrylamide flocculant metering adder, which includes a housing, feet, a storage tank, a feeding structure, a first feeding pump, a second feeding pump and a water outlet pipe; four feet for support are fixedly connected to the lower end of the housing, a storage tank is fixedly connected to the upper end of the housing, two discharge ports are opened at the left and right ends of the storage tank, the feeding structure is installed at the upper end of the storage tank, the first feeding pump is installed at the upper end of the housing and on the left side of the storage tank, the feeding port of the first feeding pump is connected to the discharge port on the left side of the storage tank through a pipeline, the second feeding pump is installed at the upper end of the housing and on the right side of the storage tank, the feeding port of the second feeding pump is connected to the discharge port on the right side of the storage tank through a pipeline, and there are two water outlet pipes which are symmetrically installed on the outer wall of the housing.

[0007] Preferably, the outer shell is made of high-strength and corrosion-resistant materials such as stainless steel. The feet play a role in supporting and stabilizing the equipment, preventing the equipment from shaking or tipping during operation. The storage tank is used to store PAM flocculant and supply PAM flocculant to the feeding pump through the discharge port. The feeding structure transports the PAM flocculant in the packaging bag into the storage tank through the suction of the feeding pump, realizing the automatic feeding function. The first feeding pump and the second feeding pump precisely adjust the dosing amount of PAM flocculant, thereby forming liquid medicines with different concentrations. The water outlet pipe discharges the liquid medicine containing PAM flocculant, thereby treating the sewage.

[0008] Preferably, the feeding structure includes a feeding pump, a telescopic hose, and an aggregate cover; the upper end of the storage tank is fixedly connected with a feeding pump. The feeding port of the feeding pump is connected to the telescopic hose, and the discharge port of the feeding pump is connected to the feeding port of the storage tank through a hose. The end of the telescopic hose is equipped with an aggregate cover. The feeding pump sucks in the PAM flocculant from the aggregate cover by generating negative pressure and transports it into the storage tank. The telescopic hose has good flexibility and wear resistance, and can adapt to the conveying requirements of different angles and distances. At the same time, its telescopic property enables the aggregate cover to adjust the position according to needs, increasing the flexibility of operation. The aggregate cover is designed in a funnel-shaped structure to effectively gather and guide the PAM flocculant into the telescopic hose.

[0009] Preferably, a first mixing tank is provided on the left side of the upper end of the outer shell, and a second mixing tank is provided on the left side of the upper end of the outer shell. Two water outlet pipes respectively extend into the first mixing tank and the second mixing tank. The first mixing tank and the second mixing tank are used for the mixing of PAM flocculant and water. Through the mixing action, the PAM flocculant can be fully dispersed in the liquid. The difference is that the concentrations of PAM flocculant in the first mixing tank and the second mixing tank are different, so that different sewage can be treated.

[0010] Preferably, a first rotating motor is installed at the upper end of the first mixing tank. A first coupling is installed at the upper end of the first rotating shaft and is connected to the output shaft of the first rotating motor through the first coupling. The lower end of the first rotating shaft extends downward into the first mixing tank. The first rotating motor is the main source of mixing power. It generates power through rotation and drives the first rotating shaft to rotate. The first coupling connects the first rotating shaft and the output shaft of the first rotating motor to achieve power transmission. The first rotating shaft is the support and transmission component of the mixing fan blades and drives the mixing fan blades to rotate.

[0011] Preferably, a second rotary motor is installed at the upper end of the second stirring tank. A second coupling is installed at the upper end of the second rotating shaft and is connected to the output shaft of the second rotary motor through the second coupling. The lower end of the second rotating shaft extends downward into the second stirring tank. The second rotary motor is the same as the first rotary motor, but serves the second stirring tank. It also generates power through rotation to drive the second rotating shaft to rotate. The second coupling is the same as the first coupling and is used to connect the second rotating shaft and the output shaft of the second rotary motor to achieve power transmission. The second rotating shaft is the same as the first rotating shaft and drives the stirring fan blades to rotate in the second stirring tank.

[0012] Preferably, the stirring fan blades are fixedly connected to the outer walls of the first rotating shaft and the second rotating shaft. The stirring fan blades are distributed along the axial directions of the first rotating shaft and the second rotating shaft respectively. The stirring fan blades are made of corrosion-resistant and wear-resistant materials such as metal. The stirring fan blades can be fixedly connected to the outer walls of the first rotating shaft and the second rotating shaft circumferentially and equidistantly by welding. This equidistant distribution can ensure that the PAM flocculant is subjected to uniform shearing, convection and diffusion effects during the stirring process, thereby improving the stirring effect.

[0013] Preferably, a fixing ring is fixedly connected to the upper end of the outer shell. Both pipes are fixedly connected to the upper end of the outer shell through the fixing ring. The fixing ring is made of metal or high-strength plastic. It has a connection structure matching the upper end of the outer shell to be firmly fixed on the outer shell. There are holes for connecting the pipes inside the fixing ring. The function of the fixing ring is to serve as a connection bridge between the pipes and the outer shell, providing a stable connection point to ensure that the two pipes can be firmly fixed on the outer shell.

[0014] Advantages of the present utility model:

[0015] 1. Through the feeding structure, the PAM flocculant can be automatically sucked from the packaging bag, effectively eliminating the cumbersome process of manual feeding. At the same time, by injecting different amounts of PAM flocculant into the first stirring tank and the second stirring tank respectively, the differential adjustment of the solution concentration is realized. This design greatly enhances the flexibility of the device in dealing with different types of sewage treatment requirements, making the treatment process more efficient and adaptable;

[0016] 2. Through the stirring of the PAM flocculant and water by the stirring fan blades, the PAM flocculant can be fully dispersed in the liquid through the stirring action. Description of the drawings
