Description

Technical Field

[0001] The utility model relates to the field of metering pump equipment, in particular to a metering pump with a quick-disassembly structure. Background Art

[0002] Fertilizer additives are chemical or biological additives used to improve soil fertility and enhance plant nutrient absorption. When improving soil conditions, fertilizer additives are usually used in conjunction with metering pumps. Metering pumps are reciprocating positive displacement pumps with adjustable discharge flow. Check valves are located at the inlet and outlet of the hydraulic flow end of the metering pump. The opening and closing of the check valve ensures the one-way flow of the material medium when passing through the metering pump, and there will be no backflow of the material medium. This enables the continuous operation of the metering pump and ensures the accuracy requirements of the metering pump during operation. The check valve is a key component in the metering pump, and its performance directly affects the overall performance of the metering pump. Metering pumps are very critical equipment in the fields of conveying highly corrosive and hazardous chemicals, health and medicine.

[0003] Existing metering pumps usually consist of a volume chamber and a drive mechanism. The drive mechanism can be electric, pneumatic or mechanical, and is used to push the fluid through the volume chamber. The volume chamber is designed with a fixed volume and geometry, which can be used to accurately contain and discharge a specific amount of fluid. The metering pump periodically delivers the fluid by controlling the filling and discharge volume of the volume chamber.

[0004] However, most of the existing metering pumps are installed and fixed by bolts. When the metering pump needs to be repaired, it is not convenient to disassemble the metering pump, which is time-consuming and labor-intensive, reduces the maintenance rate and service life of the metering pump, and limits the installation range of the metering pump.

[0006] To achieve the above-mentioned objectives, the utility model provides the following technical solutions: a metering pump with a quick-release structure, comprising a pump body, an outer wall of the pump body fixedly connected to a fixing plate, a lower surface of the fixing plate being provided with a working table, an interior of the fixing plate being fixedly connected to a fixing ring, an interior of the fixing ring being rotatably connected to a threaded ring, an outer wall of the threaded ring being rotatably connected to a sliding sleeve, one end of the threaded ring being fixedly connected to a knob, an outer wall of the threaded ring being threadedly connected to a movable ring, an outer wall of the movable ring being fixedly connected to a connecting seat, an interior of the connecting seat being rotatably connected to a first movable frame, an outer wall of the first movable frame being fixedly connected to a rotating shaft, an outer wall of the rotating shaft being rotatably connected to a second movable frame, an outer wall of the second movable frame being rotatably connected to a base, an outer wall of the base being fixedly connected to an outer wall of the sliding sleeve, and an outer wall of the pump body being provided with a driving assembly.

[0007] Furthermore, the driving assembly includes a motor, and an output end of the motor is fixedly connected to the inside of the pump body.

[0008] Furthermore, a first mounting plate is fixedly connected to an outer wall of the motor, and a sliding seat is fixedly connected to a lower surface of the first mounting plate.

[0009] Furthermore, the outer wall of the pump body is fixedly connected with a second mounting plate, a slide groove is provided inside the second mounting plate, and the outer wall of the slide seat is slidably connected inside the slide groove.

[0010] Furthermore, the outer wall of the first mounting plate is fixedly connected to a limit rod, and the outer wall of the second mounting plate is fixedly connected to a limit block.

[0011] Furthermore, a top plate is slidably connected inside the limit block, and a clamping block is fixedly connected to the upper surface of the top plate.

[0012] Furthermore, a pull rod is fixedly connected to the lower surface of the top plate, and a pull ring is fixedly connected inside the pull rod.

[0013] Furthermore, a spring is arranged inside the limit block, one end of the spring is fixedly connected to the inside of the limit block, and the other end of the spring is fixedly connected to the lower surface of the top plate.

[0014] The utility model has the following beneficial effects:

[0015] 1.

[0016] 2. In the utility model, the block is pulled out from the limit rod by pulling the pull ring, and then the first mounting plate is slid to separate the motor from the pump body, so as to achieve the effect of rapid assembly and disassembly of the motor in the metering pump, and at the same time, it is also convenient to directly clean the fertilizer additive inside the metering pump, which solves the problem that most of the motors in the existing metering pumps are directly fixed in the metering pump, which is not convenient for inspection and maintenance of the inside of the metering pump, and improves the practicality of the metering pump.

[0025] Specifically, by inserting the second movable frame 11 into the workbench 3 and turning the knob 6, the movable ring 7 slides on the outer wall of the threaded ring 5, driving the first movable frame 9 to rotate around the connecting seat 8. At the same time, the rotating shaft 10 pushes the second movable frame 11 until it is completely stuck in the workbench 3. This makes the assembly and disassembly of the metering pump faster and more convenient. By simplifying the assembly process and reducing the possibility of damage to parts, the convenience and service life of the metering pump are improved. This reduces the cost of maintenance and repair, which is convenient for metering pumps that need to be frequently replaced or maintained.

[0026] Reference Figure 1 , Figure 3 and Figure 4 The driving assembly includes a motor 13, the output end of the motor 13 is fixedly connected to the inside of the pump body 1; the outer wall of the motor 13 is fixedly connected to the first mounting plate 14, and the lower surface of the first mounting plate 14 is fixedly connected to the slide seat 15; the outer wall of the pump body 1 is fixedly connected to the second mounting plate 16, and the interior of the second mounting plate 16 is provided with a slide groove 17, and the outer wall of the slide seat 15 is slidably connected to the interior of the slide groove 17; the outer wall of the first mounting plate 14 is fixedly connected to the limiting rod 24, and the outer wall of the second mounting plate 16 is fixedly connected to the limiting block 18; the interior of the limiting block 18 is slidably connected to a top plate 19, and the upper surface of the top plate 19 is fixedly connected to a card block 20; the lower surface of the top plate 19 is fixedly connected to a pull rod 21, and the interior of the pull rod 21 is fixedly connected to a pull ring 22; a spring 23 is arranged inside the limiting block 18, one end of the spring 23 is fixedly connected to the interior of the limiting block 18, and the other end of the spring 23 is fixedly connected to the lower surface of the top plate 19;
