Description

Technical Field

[0001] The invention relates to the field of hopper cleaning, and more particularly to a hopper cleaning mechanism and a use method thereof. Background Art

[0002] In pharmaceutical and food factories, hoppers are required for the transfer of raw materials within the factory. Hoppers are generally used for the storage, transportation and distribution of raw materials. In order to meet the hygiene standards of relevant industries and ensure the safety and hygiene of raw materials, hoppers are usually made of stainless steel or other materials that meet hygiene standards to ensure that the raw materials are not contaminated. The hopper cleaning mechanism is a device used to clean the hopper. Since the hopper often contacts various raw materials and finished products, it needs to be cleaned regularly to ensure hygiene and product quality, to improve cleaning efficiency and reduce manual operations.

[0003] The Chinese patent announcement number CN220387391U discloses a hopper cleaning device, which uses an adjustment component to adjust the position of the spray head so that the spray head is aligned with and extends into the feed port of the hopper to spray water, and then the residual material in the hopper is washed away with the water flow, thereby achieving the purpose of cleaning the hopper. By installing the spray head on a frame, the working height of the spray head is increased, and a relatively high hopper can also be cleaned. Compared with manual flushing, it is simpler and more efficient, and can realize an assembly line cleaning process, thereby improving the cleaning efficiency of the hopper. The lateral driving member is used to drive the connecting member to move in the horizontal direction, and then the relative position between the spray head and the blowing head and the hopper feed port is adjusted, which is convenient for coordinated height adjustment, so that the spray head is extended into the hopper feed port or the blowing head is close to the hopper feed port, thereby improving the coordination accuracy and coordination efficiency of the spray head and the blowing head with the hopper, thereby improving the cleaning efficiency of the hopper.

[0004] In the food or pharmaceutical industry, due to the high requirements for hygiene standards, the hopper needs to be cleaned each time it is used to transport or store raw materials to meet the hygiene standards. Currently, hopper cleaning is mostly done manually or by flushing the inside with a single set of nozzles in the above solution. It is impossible to effectively clean the outer and inner walls of the hopper at the same time, which reduces efficiency and fails to meet hygiene requirements.

[0005] When you stop spraying water after flushing and the nozzle is still, the oil or scale attached to the outer surface of the nozzle and the water pipe will slide along the surface of the water pipe and the nozzle to the inside of the nozzle, and then enter the interior of the nozzle. After a long period of accumulation, dirt will easily accumulate inside the nozzle, thus affecting the hygiene of the nozzle and the amount of water sprayed.

[0006] Therefore, it is necessary to provide a hopper cleaning mechanism and a method for using the same to solve the above problems. Summary of the invention

[0007] The present invention provides a hopper cleaning mechanism and a method for using the same, which can improve the problem in the related art that the internal flushing is performed manually or by a single group of nozzles, and the outer wall and the inner wall of the hopper cannot be effectively cleaned at the same time, which reduces the efficiency and fails to meet the hygiene requirements. At the same time, when the water spraying is stopped after the flushing, the oil or scale attached to the outer surface of the nozzle and the water pipe will slide into the nozzle port and then enter the interior of the nozzle. After a long period of accumulation, the hygiene of the nozzle and the amount of water sprayed will be affected.

[0042] Optionally, in some embodiments, see Figure 7 as well as Fig.14 - Fig.16 The water spray assembly 8 includes a water spray sleeve 81 and a fixed sleeve 84.

A plurality of limiting blocks 810 are fixedly installed on the inner wall of the water outlet chamber of the water spray sleeve 81, and the limiting blocks 810 are slidably connected to the limiting grooves 85. The interior of the fixed sleeve 84 is hollow, and a plurality of water spray ports 811 connected to the interior are arranged at the outer end of the top of the fixed sleeve 84. A valve stem 86 is fixedly connected to the top of the fixed sleeve 84, and the valve stem 86 is blocked when it is inserted into the water spray port 82.

[0044] The water spray assembly 8 in this scheme is mainly used for spraying water to flush the hopper, wherein the water pipe 2 11 and the water pipe 3 13 are both provided with multiple, the water spray sleeve 81 is sleeved on the outer end of the fixed sleeve 84, and multiple limiting grooves 85 with equal spacing are provided on the outer periphery of the fixed sleeve 84, and a water outlet chamber matching the fixed sleeve 84 is provided inside the water spray sleeve 81, and multiple limiting blocks 810 are fixed on the inner wall of the water outlet chamber, and the limiting blocks 810 are slidably connected with the limiting grooves 85, so that the lower shell 91 can slide up and down outside the fixed sleeve 84, and a water spray port 1 82 is provided at the top of the water spray sleeve 81, and the water spray port 1 82 is connected with the water outlet chamber, and a magnet 87 is installed on the top of the water outlet chamber, and the fixed sleeve 8 4 is fixed with a metal ring 89 and a valve stem 86, the valve stem 86 is upwardly protruding, the magnet 87 and the metal ring 89 can be attracted to each other by magnetism, the inner wall of the water outlet chamber is also covered with a rubber sleeve 88, a plurality of water spray outlets 811 are opened at the top of the fixed sleeve 84, the water spray outlets 811 are connected with the inside, the inside of the fixed sleeve 84 is connected with the inside of the water pipe 2 11 or the water pipe 3 13, and is fixed at its outer end, the rubber sleeve 88 can fit and cover the outer end of the water spray outlet 811 at the top of the fixed sleeve 84 to block it, and a water retaining block 83 is also fixed at the top of the water spraying sleeve 81, when water is sprayed out from the water spray outlet 82, it will be blocked by the water retaining block 83 and spread in a fan shape, so that it can expand the range of spraying.

At this time, valve stem 86 extends into water spray port 1 82 to block it. The interior of a conventional nozzle is always connected to the outside. After flushing, water spraying stops, and the oil or scale attached to the outer surface of the nozzle and the water pipe will slide along the outer surface into the nozzle, and then enter the interior of the nozzle.

The valve stem 86 blocks the water outlet 82, thereby preventing residual water droplets from the outside mixed with dirt from sliding into the interior of the water spray sleeve 81, thereby achieving the effect of preventing blockage and improving hygiene. When the water starts to spray, the pressurized water will be sprayed out from the water outlet 811. At this time, the force of the water is greater than the magnetic force of the magnet 87, which will push the water spray sleeve 81 upward, so that the rubber sleeve 88 is pushed away from the top of the fixed sleeve 84, and the valve stem 86 slides out of the interior of the water outlet 82, so that the water outlet chamber is connected with the water outlet 82, so that the water flow can be sprayed out.

The pressurized water flows into the lower housing 91 through the water inlet 93 and the inner nozzle 98 to impact the impeller 147 to make it rotate. The transmission worm gear 2 1411 drives the drive shaft 146 to rotate through the multi-stage transmission, so that the connecting pipe 141 can drive the water pipe 1 12 to rotate. At this time, the water pipe 2 11 and the water pipe 3 13 will rotate to clean the outer surface and the inner wall of the hopper at the same time, thereby improving the cleaning effect. When stationary, the magnetic force of the magnet 87 attracts the metal ring 89, causing the water spray sleeve 81 to slide downward through the limit block 810, and the rubber sleeve 88 inside the water outlet chamber of the water spray sleeve 81 is tightly attached to the outside of the water spray port 2 811 at the top of the fixed sleeve 84, and the valve stem 86 extends into the water spray port 1 82 to block it, preventing the residual water droplets mixed with dirt from the outside from sliding into the interior of the water spray sleeve 81, which can prevent blockage and improve hygiene. When the water starts to spray, the force of the water is greater than the magnetic force of the magnet 87, which will push the water spray sleeve 81 upward, causing the valve stem 86 to slide out of the interior of the water spray port 1 82, so that the water flow can be sprayed out, and when the water spraying stops, it will be reset by the magnetic force.
