Description

Technical Field

[0001] This utility model relates to the field of pesticide production filtration technology, and in particular to an online filtration device for the extraction process of abamectin. Background Technology

[0002] Avermectin is a highly effective biological insecticide widely used in agriculture, animal husbandry and other fields. It has the advantages of broad spectrum, low toxicity and easy degradation. It has stomach poison and contact killing effects on pests. In the extraction process of avermectin, in order to obtain a high-purity product, the extract needs to be filtered multiple times to remove impurities, mycelium and other solid particles. Therefore, an online filtration device is used in the avermectin extraction process to filter impurities in the material production.

[0003] Existing technologies, such as patent CN205699571U, disclose an online filtration device for avermectin extraction. This patent employs an extraction column, a clarification and interception device, and a dust collection device. An alcohol spray device is located at the top of the extraction column, connected to an external condensation system. The end of the alcohol spray device, located inside the extraction column, is connected to the dust collection device. A sieve plate is installed at the bottom of the extraction column, and the clarification and interception device is mounted on the sieve plate. This invention solves the problem that in current avermectin extraction processes, the extraction column, as the equipment used in the avermectin extraction process, lacks a reusable interception device. After each batch of material completes an extraction process, operators need to enter the tank to replace the filter media. This not only extends the production cycle and increases the labor intensity of employees, but also poses a significant safety hazard to employees working in confined spaces.

[0004] In daily operation, during the filtration process of equipment, the filtration of materials generally requires multiple batches of cyclic operation. This operation is not only inefficient, but also easily causes operator poisoning when operated manually in a cyclical manner. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing equipment is difficult to filter materials in a single pass, and to propose an online filtration device for the extraction of abamectin.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an online filtration device for avermectin extraction, comprising a mounting frame, a discharge device, a feeder, a discharge pipe, and a mounting plate. The mounting plate is fixedly connected to the upper end of the mounting frame, the discharge device is fixedly connected to the upper end of the mounting frame, the discharge pipe is fixedly connected to the lower end of the discharge device, the feeder is slidably connected to the upper end of the mounting plate, an interception device is provided inside the mounting plate, the interception device includes a filter frame and a movable plate, an auxiliary component is provided inside the upper end of the mounting plate, the auxiliary component includes a slot, the movable plate is slidably connected inside the mounting plate, the filter frame is fitted to the lower end of the feeder, the slot is opened on the side of the movable plate, an insert plate is fixedly connected to the side of the filter frame, the insert plate is inserted into the slot, a filter core is fixedly connected inside the filter frame, and a sliding hole is provided on the side of the mounting plate away from the filter frame.

[0007] Furthermore, a slider is fixedly connected to the lower side of the movable plate. The slider is slidably connected inside the sliding hole. By setting the slider, the movable plate can be moved, reducing the difficulty of the movable plate moving quickly inside the mounting plate during use.

[0008] Furthermore, a threaded rod is rotatably connected inside the sliding hole, and the threaded rod is threadedly connected to the inside of the slider. The threaded rod facilitates the movement of the slider.

[0009] Furthermore, a servo motor is fixedly connected to the lower end of the threaded rod, and the servo motor is fixedly connected to the lower end of the mounting plate. The servo motor is provided to facilitate the rotation of the threaded rod.

[0010] Furthermore, the surface of the insert plate is provided with positioning holes, and a positioning rod is fixedly connected to the bottom of the slot. The positioning rod is inserted into the positioning hole. A sliding rod is fixedly connected to the upper end of the mounting plate. The feeder is slidably connected to the surface of the sliding rod. By setting the sliding rod, the feeder can be limited to move, reducing the situation where the feeder is difficult to fit with the upper end of the filter frame during use.

[0011] Furthermore, a first spring is sleeved and connected to the surface of the slide rod.

[0012] Furthermore, one end of the first spring is fixedly connected to the interior of the mounting plate, and the end of the first spring away from the mounting plate is fixedly connected to the surface of the feeder. The first spring is provided to facilitate a tight connection between the feeder and the upper end of the filter frame.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] In this invention, by setting up an interception device, during filtration, the user feeds the material into the filter frame through the feeder. The material then passes through the filter elements inside the four-layer filter frame for filtration and is discharged through the discharge pipe via the discharge device. When replacing the filter elements inside the filter frame, the servo motor is activated to drive the slider to move the moving plate. The moving plate then moves the filter frame and feeder upward to a suitable height. The upward movement of the filter frame causes the insert plate to disengage from the slot, allowing for the replacement of the filter elements inside the filter frame. This interception device, through the cooperation between components such as the filter frame, filter elements, moving plate, insert plate, threaded rod, and slider, achieves flexible and convenient replacement of the filter elements. This design eliminates the need to disassemble the entire device, making operation simple and quick, greatly saving time for replacing filter elements, improving work efficiency, and facilitating filtration maintenance during the abamectin extraction process.

[0015] In this invention, by setting an auxiliary component, when the filter frame is disassembled, the device lifts the filter frame upward, causing the insert plate to move upward inside the slot and move away from the positioning rod. This auxiliary component, through components such as slot, insert plate, positioning hole, positioning rod, slide rod and first spring, realizes the precise positioning and buffering function of the feeder, thereby improving the service life of the filter frame.

[0024] The following section will explain the specific settings and functions of its interception device 6 and auxiliary component 7.

[0025] In this embodiment: An interception device 6 is provided inside the mounting plate 5. The interception device 6 includes a filter frame 61 and a movable plate 63. An auxiliary component 7 is provided inside the upper end of the mounting plate 5. The auxiliary component 7 includes a slot 71. The movable plate 63 is slidably connected inside the mounting plate 5. The filter frame 61 is fitted to the lower end of the feeder 3. The slot 71 is opened on the side of the movable plate 63. An insert plate 65 is fixedly connected to the side of the filter frame 61. The insert plate 65 is inserted into the slot 71. A filter core 62 is fixedly connected inside the filter frame 61. A sliding hole 64 is opened on the side of the mounting plate 5 away from the filter frame 61.

[0026] Specifically, a slider 67 is fixedly connected to the lower side of the movable plate 63, and the slider 67 is slidably connected inside the sliding hole 64.

[0027] In this embodiment, by setting the slider 67, the movable plate 63 can be moved, reducing the difficulty of the movable plate 63 moving quickly inside the mounting plate 5 during use.

[0028] Specifically, a threaded rod 66 is rotatably connected inside the sliding hole 64. The threaded rod 66 is threadedly connected to the inside of the slider 67. The threaded rod 66 is provided to facilitate the movement of the slider 67.

[0029] Specifically, a servo motor 68 is fixedly connected to the lower end of the threaded rod 66. The servo motor 68 is fixedly connected to the lower end of the mounting plate 5. The servo motor 68 is set to facilitate the rotation of the threaded rod 66.

[0030] In this embodiment: the surface of the insert plate 65 is provided with a positioning hole 72, the bottom of the slot 71 is fixedly connected with a positioning rod 73, the positioning rod 73 is inserted into the positioning hole 72, the upper end of the mounting plate 5 is fixedly connected with a slide rod 74, and the feeder 3 is slidably connected to the surface of the slide rod 74.

[0031] In this embodiment, by setting the slide bar 74, the feeder 3 can be limited to move, which reduces the difficulty of the feeder 3 fitting with the upper end of the filter frame 61 when the equipment is in use.

[0032] Specifically, a first spring 75 is sleeved and connected to the surface of the slide rod 74.

[0033] Specifically, one end of the first spring 75 is fixedly connected to the inside of the mounting plate 5, and the end of the first spring 75 away from the mounting plate 5 is fixedly connected to the surface of the feeder 3. The first spring 75 is provided to facilitate a tight connection between the feeder 3 and the upper end of the filter frame 61.

[0034] Working Principle: During filtration, the user feeds the material into the filter frame 61 through the feeder 3. The material then passes through the filter cores 62 inside the four layers of filter frames 61 for filtration and is discharged through the discharge pipe 4 via the discharger 2. When replacing the filter cores 62 inside the filter frame 61, the servo motor 68 is activated to drive the slider 67 to move the moving plate 63. The moving plate 63 then moves the filter frame 61 and the feeder 3 upward to a suitable height. The upward movement of the filter frame 61 causes the insert plate 65 to disengage from the slot 71, allowing for the replacement of the filter cores 62 inside the filter frame 61. This interception device 6, through the coordination between components such as the filter frame 61, filter cores 62, moving plate 63, insert plate 65, threaded rod 66, and slider 67, achieves flexible and convenient replacement of the filter cores 62. This design eliminates the need to disassemble the entire device, making operation simple and quick, greatly saving time for replacing the filter cores 62, improving work efficiency, and facilitating filtration maintenance during the abamectin extraction process.

[0035] When the equipment disassembles the filter frame 61, it lifts the filter frame 61 upwards, causing the insert plate 65 to move upwards inside the slot 71 and move out of the positioning rod 73. This auxiliary component 7, through components such as the slot 71, insert plate 65, positioning hole 72, positioning rod 73, slide rod 74 and first spring 75, realizes the precise positioning and buffering function of the feeder 3, and improves the service life of the filter frame 61.
