Description

Technical Field

[0001] This utility model relates to the field of feeder discharge technology, and in particular to a self-cleaning feeder discharge port. Background Technology

[0002] In industries such as chemical, food, pharmaceutical and feed, feeders are key equipment for achieving accurate material metering and continuous feeding. Among them, loss-in-weight feeders are widely used for high-precision control of powder and granular materials. They adjust the feeding rate by monitoring the changes in hopper weight in real time to ensure stable flow. Liquid feeding systems are mostly used for quantitative conveying of liquid additives, viscous fluids or reactants, and have extremely high requirements for the sealing and cleanliness of the discharge port.

[0003] During the actual operation of the feeder, both powder and liquid materials are prone to residue on the inner wall of the discharge port. Especially when the machine is stopped, the material is changed, or high-viscosity, hygroscopic, or solidified materials are being conveyed, the residue will gradually accumulate at the discharge port, forming lumps, blockages, or cross-contamination, which seriously affects the accuracy of the next feeding and the product quality.

[0004] Therefore, it is necessary to design a self-cleaning feeder outlet. Utility Model Content

[0005] In order to overcome the disadvantage that feed residue easily accumulates at the discharge port, causing blockage and affecting the next feeding, the technical problem is to provide a self-cleaning feeder discharge port.

[0006] The technical implementation scheme of this utility model is as follows: A self-cleaning feeder outlet includes a discharge pipe, a mounting plate, a liquid inlet pipe, nozzles, a guide pipe, a liquid inlet valve, an annular baffle, a support plate, a cylinder, a telescopic rod, a connecting rod, and an annular scraper. The upper end of the discharge pipe is fixedly connected to the mounting plate, and the middle of the mounting plate has a discharge outlet corresponding to the discharge pipe. A liquid inlet pipe is fixedly installed on the inner wall of the discharge outlet in the middle of the mounting plate. A certain number of nozzles are evenly fixedly connected to the lower end of the liquid inlet pipe. A guide pipe is fixedly installed in the middle of the front side of the liquid inlet pipe. An infusion valve is fixedly installed in front of the mounting plate and the guide pipe. An annular baffle is fixedly installed on the inner wall of the discharge port in the middle of the mounting plate. The infusion pipe is located below the annular baffle. A support plate is fixedly connected between the front and rear side walls of the annular baffle. A cylinder is fixedly installed in the middle of the upper surface of the support plate. A telescopic rod is fixedly installed in the middle of the lower surface of the support plate. The movable end of the cylinder slides through the lower part of the support plate and is fixedly connected to the telescopic rod. A connecting rod is fixedly connected to the lower end of the telescopic rod. An annular scraper is fixedly installed around the connecting rod. The annular scraper is in close contact with the inner wall of the discharge pipe.

[0007] As a preferred technical solution of this utility model, mounting positioning holes are provided on both the left and right sides of the mounting plate.

[0008] As a preferred technical solution of this utility model, the spraying range of the nozzle is the inner wall of the discharge pipe.

[0009] As a preferred embodiment of this utility model, the annular baffle, the support plate, the connecting rod, and the inner wall of the annular scraper all have beveled edges.

[0010] As a preferred technical solution of this utility model, it also includes a protective sleeve, which is fixedly provided on the upper surface of the support plate and covers the cylinder.

[0011] As a preferred technical solution of this utility model, a certain number of heat dissipation holes are fixedly opened on the side wall of the protective sleeve, and the heat dissipation holes are inclined downward.

[0012] 1. This utility model, by setting up an infusion pipe, a nozzle, a guide pipe and an infusion valve, sprays cleaning liquid into the discharge pipe when the machine is stopped or the material is changed, dissolving or softening the residual material adhering to the inner wall, thereby effectively preventing material accumulation and cross-contamination.

[0013] 2. This utility model, by setting up a cylinder, a telescopic rod, a connecting rod, and an annular scraper that is in close contact with the inner wall of the discharge pipe, allows the cylinder to drive the annular scraper to move up and down after the cleaning liquid is applied, physically scraping the inner wall of the discharge pipe to thoroughly remove stubborn residues, thus achieving efficient self-cleaning and preventing clogging of the discharge port.

[0019] Example: A self-cleaning feeder outlet, such as... Figures 1-4As shown, the system includes a discharge pipe 1, a mounting plate 2, an infusion pipe 3, a nozzle 4, a guide pipe 5, an infusion valve 6, an annular baffle 7, a support plate 8, a cylinder 9, a telescopic rod 11, a connecting rod 12, and an annular scraper 13. The upper end of the discharge pipe 1 is fixedly connected to the mounting plate 2. The mounting plate 2 has a discharge port corresponding to the discharge pipe 1 in its middle. An infusion pipe 3 is fixedly installed on the inner wall of the discharge port in the middle of the mounting plate 2. A certain number of nozzles 4 are evenly fixedly connected to the lower end of the infusion pipe 3. A guide pipe 5 is fixedly installed in the middle of the front side of the infusion pipe 3. The guide pipe 5 passes through the front of the mounting plate 2. An infusion valve 6 is fixedly installed in front of the guide pipe 5. An annular baffle 7 is fixedly installed on the inner wall of the discharge port in the middle of the mounting plate 2. Liquid pipe 3 is located below annular baffle 7. A support plate 8 is fixed between the front and rear side walls of annular baffle 7. A cylinder 9 is installed in the middle of the upper end face of support plate 8 by screws. A telescopic rod 11 is fixed in the middle of the lower end face of support plate 8. The movable end of cylinder 9 slides through the lower part of support plate 8 and is fixed to telescopic rod 11. A connecting rod 12 is fixed to the lower end of telescopic rod 11. An annular scraper 13 is fixed around the connecting rod 12. The annular scraper 13 is in close contact with the inner side wall of discharge pipe 1. Installation positioning holes are opened on both the left and right sides of mounting plate 2. The spraying range of nozzle 4 is the inner side wall of discharge pipe 1. The inner side walls of annular baffle 7, support plate 8, connecting rod 12 and annular scraper 13 are all beveled.

[0020] like Figure 1 , Figure 2 and Figure 4 As shown, it also includes a protective sleeve 10. The protective sleeve 10 is fixedly installed on the upper end face of the support plate 8. The protective sleeve 10 covers the cylinder 9. A certain number of heat dissipation holes are fixedly opened on the side wall of the protective sleeve 10. The heat dissipation holes are inclined downwards.

[0021] When using this device, materials are normally conveyed through the discharge port in the middle of the mounting plate 2 and the discharge pipe 1. When the feeding process ends or the material needs to be replaced, in order to prevent residual materials from accumulating on the inner wall of the discharge pipe 1 and causing blockage or cross-contamination, a self-cleaning program can be activated. First, cleaning fluid is introduced through the infusion valve 6 on the front side of the guide pipe 5. The cleaning fluid is conveyed through the guide pipe 5 to the infusion pipe 3 fixed on the inner wall of the discharge port of the mounting plate 2. Finally, the fluid is sprayed onto the inner wall of the discharge pipe 1 by the evenly distributed nozzles 4 at the lower end of the infusion pipe 3 to rinse and initially dissolve the attached residual powder or liquid materials. The infusion pipe 3 is located below the annular baffle 7. A support plate 8 is fixedly connected between the front and rear side walls of the annular baffle 7. A cylinder 9 is installed in the middle of the upper surface of the support plate 8. A protective sleeve 10 is provided around the cylinder 9 to provide protection. Several downward-sloping heat dissipation holes are opened on the side wall of the protective sleeve 10 to discharge the heat generated by the cylinder 9 during operation. Meanwhile, it effectively blocks the intrusion of external liquids or dust. The movable end of the cylinder 9 passes downward through the support plate 8 and is fixedly connected to the telescopic rod 11. The lower end of the telescopic rod 11 is fixed with a connecting rod 12. An annular scraper 13 is fixedly installed around the connecting rod 12. The scraper is in close contact with the inner wall of the discharge pipe 1. When the nozzle 4 sprays cleaning liquid to soften or dissolve the residue, the cylinder 9 is activated, pushing the telescopic rod 11 downward, which in turn moves the connecting rod 12 and the annular scraper 13 down along the inner wall of the discharge pipe 1, thereby thoroughly scraping away the residue and achieving physical cleaning. The scraped-off dirt is discharged along with the cleaning liquid. After cleaning is completed, the cylinder 9 is reset, which moves the annular scraper 13 upward back to the initial position. The mounting plate 2 has mounting and positioning holes on both the left and right sides to securely install the entire discharge structure on the feeding equipment. The inner sides of the annular baffle 7, support plate 8, connecting rod 12 and annular scraper 13 are all beveled to help the material pass smoothly and reduce dead corners of material accumulation.
