Description

Technical Field

[0001] The utility model relates to the technical field of kitchen waste cleaning, and in particular to a contactless automatic cleaning device for the wall of a kitchen waste silo. Background Art

[0002] Domestic waste is divided into kitchen waste, recyclables, hazardous waste and other waste, which are collected, transported and disposed of separately. Among them, restaurant waste, kitchen waste and waste grease all contain a large amount of oil pollution. The existing technology has the following problems:

[0003] Because the walls of the receiving silos of existing waste treatment plants are mainly cleaned by on-site operators using handheld spray guns to clean the oil accumulated on the unloading platform, the receiving silos are usually designed to be deeper than 4.5m due to the size of the unloading truck, resulting in the side and rear walls of the silo being beyond the flushing range of the handheld spray gun. The oil has accumulated here for years and continuously emits unorganized odor. At the same time, some existing plant areas have designed walkways around the unloading pits to facilitate workers to enter the silo to clean the silo walls. However, the oil makes the ground slippery, and workers are prone to falling into the pit, which may cause safety accidents. At the same time, the effect of cold water cleaning cannot meet the deodorization requirements. Utility Model Content

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] The matching instrument valve control mechanism 5 realizes the functions of automatic water inlet, automatic temperature control, automatic start and stop, and adjustment of flushing pressure of the system. By observing the thermometer 22, the desired flushing temperature can be set to control the opening and closing of the steam opening and closing solenoid valve 23 to adjust the flushing water temperature in the range of 0℃ to 100℃. When the liquid level meter 21 shows a high liquid level, the steam opening and closing solenoid valve 23 at the water inlet pipe end is closed to stop water inlet. When the liquid level meter 21 shows a low liquid level, the steam opening and closing solenoid valve 23 is opened to replenish water into the steam direct injection hot water storage tank 24. The water inlet of the steam heating water tank mechanism 2 is softened water obtained by the softening and filtering water system 1, which can prevent the system from scaling the pipes and nozzles 43 due to the cooling of hot water. The cation exchanger 12 and the cation exchanger 2 13 obtain the necessary brine components from the salt storage tank 11, thereby softening the water and inputting it into the steam direct injection hot water storage tank 24.

[0024] like Figure 4 As shown, the four rotary cleaning units 4 respectively include a rotary motor 41 and two solenoid valves 44. A long plate is fixedly installed on one side of the rotary motor 41, and four rotary bearings 42 are evenly fixedly installed on the top of the long plate. The output ends of one side of the four rotary bearings 42 are all screwed with nozzles 43, and the output ends of the other sides of the four rotary bearings 42 are respectively provided with transmission belts 45, and the transmission belts 45 are driven by the output end of the rotary motor 41.

[0025] The rotating motor 41 controls the four rotating bearings 42 to rotate 360 degrees through the transmission belt 45, so that the entire area of the warehouse wall is covered without leaving any dead corners for flushing. The four rotating bearings 42 are respectively screwed to a nozzle 43. At the same time, the nozzles 43 are grouped into two and controlled to start and stop by a solenoid valve 44, which can meet the requirements of segmented flushing. Multiple flushing of a certain section can be determined according to actual use to save water.

[0026] like Figure 5 As shown, a liquid extraction pipe 111 is provided on the top of the salt storage tank 11, and the output end of the liquid extraction pipe 111 passes through the inner cavity of the salt storage tank 11 and is fixedly connected to an L-shaped changing tube 112, and the bottom end of the vertical part of the L-shaped changing tube 112 is located above the center of the bottom circle of the inner wall of the salt storage tank 11, and a motor 113 is fixedly installed at the center of the bottom circle of the salt storage tank 11, and the output shaft of the motor 113 passes through the inner cavity of the salt storage tank 11 and is fixedly installed with L-shaped stirring rods 114 on both sides, and stirring rods 115 are fixedly installed on the left and right sides of the vertical parts of the two L-shaped stirring rods 114, and the vertical parts of the two L-shaped stirring rods 114 are respectively located on the left and right sides of the vertical part of the L-shaped changing tube 112, and the other end of the stirring rod 115 on one side of the L-shaped changing tube 112 at the vertical part of the two L-shaped stirring rods 114 is fixedly installed with a scraper 116, and the other sides of the two scrapers 116 are overlapped with the inner wall of the salt storage tank 11;

[0027] Since the salt water necessary for softening water is stored in the salt storage tank 11, which contains a large amount of salt, in order to prevent salt precipitation, the motor 113 at the bottom of the salt storage tank 11 can be started to drive its output shaft to penetrate the L-shaped stirring rods 114 installed on the left and right sides of the inner cavity of the salt storage tank 11 to rotate, and the two L-shaped stirring rods 114 are vertically connected to the left and right sides of the stirring rods 115 to continuously stir the salt water in the salt storage tank 11 to prevent salt precipitation. At the same time, the vertical part of the L-shaped changing tube 112 is located at On the vertical line at the center of the salt storage tank 11, brine can be normally extracted from the bottom of the salt storage tank 11 and input into the cation exchanger 12 and the cation exchanger 2 13 through the liquid extraction pipe 111 and the control of the water inlet and outlet control valve group 14. At the same time, while the two L-shaped stirring rods 114 rotate, the scraper 116 at one end of the stirring rod 115 can be used to contact the inner wall of the salt storage tank 11 to repeatedly scrape the inner wall of the salt storage tank 11 to prevent salt from adhering to the inner wall of the salt storage tank 11 and affecting subsequent cleaning work.

[0028] The following is a detailed description of the working principle of the contactless automatic cleaning equipment for the wall of kitchen waste silo.

[0029] like Figure 1-5As shown, the system realizes the functions of automatic water inlet, automatic temperature control, automatic start and stop, and adjustment of flushing pressure through the matching instrument valve control mechanism 5. By observing the thermometer 22, the desired flushing temperature can be set to control the opening and closing of the steam opening and closing electromagnetic valve 23 to adjust the flushing water temperature in the range of 0℃ to 100℃. When the liquid level meter 21 shows a high liquid level, the steam opening and closing electromagnetic valve 23 at the water inlet pipe end is closed to stop water inlet. When the liquid level meter 21 shows a low liquid level, the steam opening and closing electromagnetic valve 23 is opened to replenish water in the steam direct injection hot water storage tank 24. The water inlet of the steam heating water tank mechanism 2 is first softened. The softened water produced by the filtered water system 1 can prevent scaling of the pipes and nozzles 43 caused by the cooling of hot water. The rotating motor 41 controls the four rotating bearings 42 to rotate 360 degrees through the transmission belt 45, so as to achieve full coverage of the warehouse wall without leaving any blind spots for flushing. The four rotating bearings 42 are respectively screwed to a nozzle 43. At the same time, the nozzles 43 are grouped into two and controlled to start and stop by a solenoid valve 44, which can meet the requirements of segmented flushing. The multiple flushing of a certain section can be determined according to actual use to save water. The high-pressure water pump 3 can adjust the flushing pressure of the nozzle 43 within the range of 0 to 150 bar through frequency conversion control.

[0030] While the present invention has been generally described above, it is readily apparent to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are intended to be within the scope of protection of the present invention.
