Description

Technical Field

[0001] This utility model relates to the field of dosing pump technology, and in particular to a filter device for a dosing pump. Background Technology

[0002] Dosing pumps are mainly used for livestock and poultry drug treatment, disinfection, cleaning, agricultural fertilization and plant protection, sanitary flocculation treatment, vehicle washing, etc. In the process of adding metered agents in environmental protection machinery, water treatment equipment and various industries, a dosing process is required.

[0003] In existing technologies, adding chemicals usually requires the use of water to dissolve and dilute them. However, the dosing pump does not have a filter device at the inlet. If there are residues in the dissolved chemicals, there is a risk of clogging. Moreover, impurities in the water source accumulate inside the dosing pump, causing damage and accelerating its aging. This increases the overall operating cost and the workload of subsequent cleaning by the staff. Therefore, a filter device is necessary. Utility Model Content

[0005] The problem is...

[0006] To address the aforementioned problems, this utility model provides a filtration device for a dosing pump, comprising a filter tank, a filter screen cylinder, and a stirring mechanism. The filter tank has a discharge port at its bottom, with a valve at the discharge port. The filter tank has a sealing cover at its top, with a connecting ring on its lower surface. The top of the sealing cover has a water inlet and a dosing port. A filter tube is threadedly connected to the water inlet. The filter screen cylinder is threadedly connected to the connecting ring. The stirring mechanism consists of a motor, a stirring shaft, and stirring rods. The motor is mounted on the top of the sealing cover, and its power output shaft rotates through the sealing cover and connects to the stirring shaft. The stirring rods are equidistantly mounted on the stirring shaft, which is located inside the filter screen cylinder. Two connecting plates are symmetrically mounted on both sides of the top of the sealing cover. Two electric telescopic rods are symmetrically mounted on both sides of the filter tank, with their telescopic ends connected to the connecting plates.

[0007] Preferably, a plurality of funnel-shaped filter screens are installed at equal intervals inside the filter tube, the plurality of filter screens are connected by a support frame, and the bottom of the support frame is connected to an installation ring, which is threaded to the bottom inner side of the filter tube.

[0008] Preferably, the water inlet and the chemical dosing port are located above the filter screen cylinder.

[0009] Preferably, the stirring shaft and stirring rod are located inside the filter screen cylinder.

[0010] The beneficial effects of adopting the above technical solutions are:

[0011] By installing a filter pipe at the water inlet, the water is filtered, thus preventing impurities in the water source from accumulating inside the dosing pump, which could cause damage and aging, and extending the service life of the dosing pump.

[0012] The combination of the stirring mechanism and the filter cylinder can fully mix and filter the medicine and water, improving the quality of subsequent work.

[0013] The electric telescopic rod allows the sealing cover to be lifted, thereby pushing the stirring mechanism and filter screen cylinder out of the filter tank, facilitating maintenance and cleaning and improving the convenience of maintenance work. Attached Figure Description

In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, a movable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] like Figure 1-3 In this embodiment, a filtration device for a dosing pump includes a filter tank 1, a filter screen cylinder 2, and a stirring mechanism 3. The filter tank 1 has a discharge port 11 at its bottom, and a valve 12 at the discharge port 11. The filter tank 1 has a sealing cover 4 at its top, and a connecting ring 41 is provided on the lower surface of the sealing cover 4. The sealing cover 4 has a water inlet 5 and a dosing port 6 at its top. A filter pipe 51 is threadedly connected to the water inlet 5. The filter screen cylinder 2 is threadedly connected to the connecting ring 41. The stirring mechanism 3 consists of a motor 31, a stirring shaft 32, and a stirring rod 33. The motor 31 is installed on the top of the sealing cover 4, and its power output shaft rotates through the sealing cover 4 and is connected to the stirring shaft 32. The stirring rod 33 is equidistantly installed on the stirring shaft 32, and the stirring shaft 32 is located inside the filter screen cylinder 2. Two connecting plates 42 are symmetrically installed on both sides of the top of the sealing cover 4. Two electric telescopic rods 43 are symmetrically installed on both sides of the filter tank 1, and the telescopic ends of the electric telescopic rods 43 are connected to the connecting plates 42.

[0022] With the above technical solution, during use, the discharge port 11 is connected to the dosing pump, and then the water source is sent into the filter pipe 51 through the water inlet 5 for water filtration. The filtered water enters the filter tank 1, and the medicine is sent into the filter tank 1 through the dosing port 6. At this time, the valve 12 is in the closed state. Then, the motor 31 in the stirring mechanism 3 is started to drive the stirring shaft 32 and stirring rod 33 to rotate, stirring the water and medicine. Then, the filter screen cylinder 2 further filters the stirred medicine solution. After filtration, the valve 12 is opened, and the medicine solution is sent into the dosing pump through the discharge port 11. Through the action of the two electric telescopic rods 43, the sealing cover 4 can be pushed upward, thereby driving the stirring mechanism 3 and the filter screen cylinder 2 to detach from the filter tank 1. The filter screen cylinder 2 is threadedly connected to the connecting ring 41, which facilitates loading and unloading. This makes it easy to clean the stirring shaft 32, stirring rod 33 and filter screen cylinder 2 in the stirring mechanism 3 from the outside, improving the filtration effect and facilitating the cleaning and maintenance of the equipment.

[0023] Preferably, a plurality of funnel-shaped filter screens 52 are installed equidistantly inside the filter tube 51. The plurality of filter screens 52 are connected to each other by a support frame 53, and an installation ring 54 is connected to the bottom of the support frame 53. The installation ring 54 is threadedly connected to the bottom inner side of the filter tube 51.

[0024] Through the above technical solution, the funnel-shaped filter screen 52 in the filter tube 51 is used to filter water and remove impurities from the water. At the same time, since the mounting ring 54 is threadedly connected to the filter tube 51, it is easy to install and remove the filter screen 52, and easy to clean and maintain.

[0025] Preferably, the water inlet 5 and the chemical dosing port 6 are located above the filter cylinder 2.

[0026] The above technical solution ensures that water and chemicals first enter the filter cylinder 2, thereby guaranteeing the effectiveness of subsequent stirring and filtration.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate this utility model and are not intended to limit the technical solutions described in this utility model. Therefore, although this specification has described this utility model in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model, and all technical solutions and improvements that do not depart from the spirit and scope of this utility model should be covered within the scope of the claims of this utility model; technologies not described in detail in this utility model are implemented using existing technologies.
