Description

Technical Field

[0001] This utility model relates to the field of kitchen waste treatment technology, specifically a vacuum conveying device for kitchen waste treatment. Background Technology

[0002] Kitchen waste refers to easily perishable, spoiled, and smelly food scraps generated after eating and drinking. These include discarded vegetable stalks and leaves, fruit peels, eggshells, animal offal, rice and grains, meat products, bean residue, seafood, bone fragments, soup residue, dessert crumbs, etc.

[0003] Food waste has a significant dual nature of being both harmful and a resource. It has an extremely high water and salt content, and is rich in organic matter and various trace elements, such as protein, cellulose, starch, fat, nitrogen, phosphorus, potassium, and calcium. It is very easy for it to breed a large number of pathogens and microorganisms, and then decompose and smell bad under the corrosion of bacteria and microorganisms, which can harm human health.

[0004] In response to the harm caused by food waste, a technology has been invented to process food waste, turning it into organic fertilizer raw materials, thereby realizing the reuse of resources.

[0005] In order to achieve rapid processing of food waste, how to efficiently and quickly transport food waste is a problem we need to solve now.

[0006] A vacuum conveying device for food waste treatment has been invented in modern society. This device can effectively and quickly suck up and store food waste and then discharge it into the food waste treatment unit. It is very useful and convenient. However, some existing vacuum conveying devices for food waste treatment use negative pressure suction technology when sucking up food waste. Therefore, the device needs to use a filter mechanism to filter the food waste to prevent it from being sucked into the vacuum pump and causing pollution and damage to the vacuum pump. However, long-term use may affect the filtration performance of the filter mechanism, resulting in poor filtration effect of the filter screen and affecting the working effect of the vacuum pump. At this time, it is quite troublesome to remove the filter mechanism for cleaning and increase the consumption of manpower and time. Replacing the filter mechanism directly will increase the cost budget. Utility Model Content

[0007] Therefore, the purpose of this utility model is to provide a vacuum conveying device for food waste treatment, so as to solve the technical problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a vacuum conveying device for food waste treatment, comprising a vacuum conveyor body, a feed pipe connected to one side of the vacuum conveyor body, a discharge port at the bottom of the vacuum conveyor body, a discharge valve installed on the outer side of the discharge port, a conveyor top cover connected to the top of the vacuum conveyor body via a flange connection, a vent pipe connected to one side of the conveyor top cover, a first suction pipe connected to the other side of the conveyor top cover, a back-blowing assembly installed on the top of the conveyor top cover, and an annular limiting mounting bracket fixedly installed on the inner side of the conveyor top cover. A filter mechanism is fixedly installed on the inner side of the conveyor. A cleaning assembly is also provided inside the top cover of the conveyor. One end of the first suction pipe is connected to a processing box, and the top side of the processing box is connected to a second suction pipe. The other end of the second suction pipe is connected to a vacuum pump. The cleaning assembly includes a limiting support sleeve, which is installed at the center of an annular limiting mounting frame. Multiple connecting support rods are fixedly connected between the limiting support sleeve and the annular limiting mounting frame. A rotating shaft is movably connected to the inner side of the limiting support sleeve. An impeller is fixedly installed at the top of the rotating shaft. Multiple cleaning rotating rods are provided on the outer side of the bottom end of the rotating shaft. Multiple cleaning brushes are installed on the top side of the cleaning rotating rods.

[0009] By adopting the above technical solution, a feed pipe is used to suck up and transport kitchen waste, a discharge port is used to discharge the sucked kitchen waste into the kitchen waste treatment device, a discharge valve is used to control the opening and closing of the discharge port, a ring-shaped limit mounting bracket is used to facilitate the installation of the filter mechanism and cleaning components, a back-flushing component is used so that after the device completes the suction and conveying work, the back-flushing component can provide power to the cleaning component, and the back-flushing component itself can also clean the filter mechanism to a certain extent through the blown gas, thereby enhancing the filtration effect and capacity of the filter mechanism, and a cleaning component is used to wash and clean the bottom of the filter mechanism, thereby improving the use effect of the multiple filter screens, extending the service life of the multiple filter screens, and avoiding the need for manual cleaning of the filter mechanism, saving the manpower and time wasted on manual cleaning, and a treatment box is used to dehumidify the gas extracted by the vacuum pump. To prevent moisture from food waste from entering the vacuum pump and causing damage, thus extending the vacuum pump's lifespan, the vacuum pump removes gas from the vacuum conveyor body, creating negative pressure inside to suck up and transport external food waste. Connecting support rods are used to fix and support the limiting support sleeve, which in turn limits the rotating shaft. The rotating shaft connects the impeller and the cleaning rod. When the impeller rotates under the action of the back-blowing component, it simultaneously drives the rotating shaft and the cleaning rod to rotate. The impeller, when the back-blowing component sprays air, is affected by the gas, causing it to rotate and converting the kinetic energy of the gas in the back-blowing component into the mechanical energy of the impeller's rotation. The cleaning rod and cleaning brushes, used by the impeller driving the cleaning rod, clean the bottom of the multiple filter screens.

[0010] The present invention is further configured such that the filtering mechanism is a multi-layer filter screen, the multi-layer filter screen is fixed on the inner side of the annular limiting mounting bracket, and the center of the multi-layer filter screen is hollow.

[0011] By adopting the above technical solution, multiple filters are used to filter the collected kitchen waste, preventing it from being sucked into the vacuum pump and causing pollution and damage to the vacuum pump. By making the center of the multiple filters hollow, it is easier to install the limit support sleeve.

[0012] The present invention is further configured such that the backflush assembly includes a backflush air pipe, the backflush air pipe is installed on the top of the conveyor top cover, a backflush air bag is connected to the top of the backflush air pipe, an air pipe valve is installed on the outside of the backflush air pipe, a connecting air pipe is connected to the bottom of the backflush air pipe, the connecting air pipe passes through the top of the conveyor top cover and is connected to the backflush air port, and an annular air guide plate is provided on the inner side of the top annular limiting mounting bracket of the multi-layer filter screen, the annular air guide plate is fixedly installed on the outside of multiple connecting support rods.

[0013] By adopting the above technical solution, a backflush air manifold is used to store high-pressure gas. After the food waste collection and transportation work is completed, the high-pressure gas can be ejected from the backflush air port by opening the air pipe valve, passing through the backflush air pipe and the connecting air pipe. The connecting air pipe connects the backflush air pipe and the backflush air port, and the annular air guide plate guides the gas ejected from the backflush air port. The gas ejected from the backflush air port surrounds the inner side of the annular air guide plate and blows downwards onto the entire plane of the multi-layer filter screen, thereby maximizing the cleaning and unclogging of the multi-layer filter screen.

[0014] The present invention is further configured such that: an air guide pipe is provided inside the processing box; one end of the air guide pipe is connected to a first suction pipe; an air guide fan is movably connected inside the air guide pipe; a filter screen is installed on the top of the air guide pipe; limit support frames are fixed on both symmetrical sides inside the processing box; an adsorption turntable is movably connected to the inner side of the limit support frame; a motor is fixedly installed on one side wall inside the processing box; a rotor is connected to the output end of the motor; belt grooves for installing a conveyor belt are opened on the outer sides of both the adsorption turntable and the rotor; and the conveyor belt is driven and connected in the belt grooves of the adsorption turntable and the rotor.

[0015] By adopting the above technical solution, the extracted gas is guided and transported using a gas guide pipe and a gas guide fan, the extracted gas is further filtered using a filter screen, the adsorption turntable is limited and supported using a limiting support frame, the adsorption turntable is used to dehumidify the extracted air, and the adsorption turntable is driven to rotate using a motor, a conveyor belt, and a rotor, so that the entire surface of the adsorption turntable can be evenly contacted with the extracted gas, thereby maximizing the adsorption of water vapor by the adsorption turntable.

[0016] The present invention is further configured such that a feed inlet is installed at the end of the feed pipe.

[0017] By adopting the above technical solution, the feed inlet can be used to more effectively and conveniently absorb kitchen waste.

[0018] The present invention is further configured such that pipe valves are installed on the outer sides of both the vent pipe and the first extraction pipe.

[0019] By adopting the above technical solution, the opening and closing of the two pipes, the ventilation pipe and the first extraction pipe, can be controlled by using pipeline valves.

[0020] The present invention is further configured such that the opening of the backflush port is inclined.

[0021] By adopting the above technical solution, the backflush port can blow gas at an angle toward the impeller, allowing the impeller to be better powered by the gas to rotate and achieve the best conversion effect.

[0022] The present invention is further configured such that the adsorption turntable has a honeycomb structure, and active silicone is provided in each honeycomb groove.

[0023] By adopting the above technical solution, the interior of the adsorption disc has a sufficiently large area to contact the gas drawn in by the vacuum pump, and after contact, the water vapor in the gas is fully adsorbed by the active silica gel and thus removed.

[0024] In summary, the present invention has the following main advantages:

[0025] 1. This utility model features a cleaning component that allows for the washing and cleaning of the bottom of the filter mechanism. A back-blowing component provides power to rotate the impeller, which in turn rotates the cleaning rod. This causes the cleaning brushes on the cleaning rod to rotate and wash the bottom of the multiple filter screens, removing food waste adhering to the bottom of the multiple filter screens. This improves the effectiveness of the multiple filter screens, extends their service life, and eliminates the need for manual cleaning of the filter mechanism, saving manpower and time.

[0026] 2. This utility model provides power to the cleaning component by setting a backflush component, and the backflush component itself can also clean the filter mechanism to a certain extent by blowing out the gas. By spraying high-pressure gas from the backflush air tank out from the backflush air port, and because the opening of the backflush air port is set at an angle, the backflush air port can blow the gas at an angle towards the impeller, so that the impeller can be better powered by the gas to rotate and obtain the best energy conversion effect. Then, the gas passing through the impeller will be guided by the annular air guide plate and blow and clean the multiple filter screens in a spiral manner, thereby improving the filtration effect of the multiple filter screens.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0034] The embodiments of this utility model will be described below based on its overall structure.

[0035] A vacuum conveying device for food waste treatment, such as Figure 1 - Figure 5As shown, the device includes a vacuum conveyor body 1. A feed pipe 11 is connected to one side of the vacuum conveyor body 1, and a feed inlet 14 is installed at the end of the feed pipe 11. The feed pipe 11 is used to suck up and transport kitchen waste, and the feed inlet 14 allows for more efficient and convenient suction of the kitchen waste. A discharge port 12 is located at the bottom of the vacuum conveyor body 1, allowing the sucked kitchen waste to be discharged into a kitchen waste treatment device. A discharge valve 13 is installed on the outside of the discharge port 12, controlling its opening and closing. A conveyor top cover 2 is connected to the top of the vacuum conveyor body 1 via a flange connection 3. A vent pipe 21 is installed on one side of the conveyor top cover 2, and a first suction pipe 22 is installed on the other side. Pipe valves 25 are installed on the outer sides of both the vent pipe 21 and the first suction pipe 22, allowing control of their opening and closing. A backflushing assembly 4 is installed on the top of the conveyor top cover 2. An annular limiting mounting bracket 23 is fixedly installed on the inner side of the conveyor top cover 2, and a filter mechanism, consisting of multiple filter screens 24, is fixedly installed inside the annular limiting mounting bracket 23. A cleaning assembly 5 is also installed inside the conveyor top cover 2. The center of pipe 24 is hollow, which facilitates the installation of the cleaning component 5. One end of the first suction pipe 22 is connected to the processing box 6, and the top side of the processing box 6 is connected to the second suction pipe 69. The other end of the second suction pipe 69 is connected to the vacuum pump 7. The installation of the multiple filter screen 24 and the cleaning component 5 is facilitated by the annular limiting mounting bracket 23. The multiple filter screen 24 filters the collected kitchen waste, preventing it from being sucked into the vacuum pump 7 and causing pollution and damage. The back-blowing component 4 provides power to the cleaning component after the device completes the suction and conveying work, and the back-blowing component 4 itself can also protect the filter mechanism with the blown gas. The cleaning component 5 cleans and removes blockages, enhancing the filtration effect and capacity of the filter mechanism. It washes and cleans the bottom of the multiple filter screens 24, improving their performance and extending their lifespan. This eliminates the need for manual cleaning, saving manpower and time. The processing box 6 dehumidifies the gas drawn by the vacuum pump 7, preventing moisture from food waste from entering and damaging the pump, thus extending its lifespan. The vacuum pump 7 also removes gas from the vacuum conveyor body 1, creating negative pressure to draw and transport external food waste.The cleaning assembly 5 includes a limiting support sleeve 51, which is installed at the center of an annular limiting mounting bracket 23. Multiple connecting support rods 52 are fixedly connected between the limiting support sleeve 51 and the annular limiting mounting bracket 23. A rotating shaft 53 is movably connected to the inner side of the limiting support sleeve 51. An impeller 54 is fixedly installed at the top of the rotating shaft 53. Multiple cleaning rotating rods 55 are provided on the outer side of the bottom end of the rotating shaft 53. Multiple cleaning brushes 56 are installed on the top side of the cleaning rotating rods 55. The limiting support sleeve 51 is fixedly supported by the connecting support rods 52. The rotating shaft 53 is provided with limiting support, connecting the impeller 54 and the cleaning rod 55. When the impeller 54 rotates under the action of the back-blowing assembly 4, it simultaneously drives the rotating shaft 53 and the cleaning rod 55 to rotate. The impeller 54, when the back-blowing assembly 4 is spraying air, is rotated by the gas effect, converting the kinetic energy of the gas in the back-blowing assembly 4 into the mechanical energy of the impeller 54's rotation. The cleaning rod 55 and cleaning brush 56 ensure that when the impeller 54 drives the cleaning rod 55 to rotate, the cleaning brush 56 cleans the bottom of the multi-layer filter screen 24.

[0036] Please see Figure 2 and Figure 3 The backflush assembly 4 includes a backflush air pipe 41, which is installed on the top of the conveyor top cover 2. A backflush air manifold 42 is connected to the top of the backflush air pipe 41. An air pipe valve 43 is installed on the outside of the backflush air pipe 41. A connecting air pipe 44 is connected to the bottom of the backflush air pipe 41. The connecting air pipe 44 passes through the top of the conveyor top cover 2 and connects to the backflush air port 45. The opening of the backflush air port 45 is inclined, allowing the backflush air port 45 to blow gas obliquely towards the impeller 54, enabling the impeller 54 to be better powered by the gas and achieve optimal conversion effect. An annular air guide plate 46 is provided on the inner side of the top annular limiting mounting bracket 23 of the multi-layer filter screen 24. An annular air guide plate 46 is fixedly installed on the outside of multiple connecting support rods 52. High-pressure gas is stored by a backflush air bag 42. After the food waste collection and transportation work is completed, the high-pressure gas can be sprayed out from the backflush air port 45 by opening the air pipe valve 43, along the backflush air pipe 41, the connecting air pipe 44 and finally the backflush air port 45. The backflush air pipe 41 and the backflush air port 45 are connected by the connecting air pipe 44. The annular air guide plate 46 guides the gas sprayed from the backflush air port 45, so that the gas sprayed from the backflush air port 45 surrounds the inner side of the annular air guide plate 46 and blows downwards onto the entire plane of the multi-layer filter screen 24, thereby maximizing the cleaning and unclogging of the multi-layer filter screen 24.

[0037] Please see Figure 5The processing chamber 6 has an internal air guide pipe 61, which is connected to one end of the first suction pipe 22. An air guide fan 62 is movably connected inside the air guide pipe 61. A filter screen 63 is installed on the top of the air guide pipe 61. Limiting support frames 64 are fixed symmetrically on both sides inside the processing chamber 6. An adsorption turntable 65 is movably connected to the inner side of the limiting support frame 64. The adsorption turntable 65 has a honeycomb structure, and activated silica gel is provided in each honeycomb groove, ensuring sufficient surface area for contact with the gas drawn in by the vacuum pump 7. After contact, water vapor in the gas is fully adsorbed and removed by the activated silica gel. A motor 66 is fixedly installed on one side wall inside the processing chamber 6, and a rotor 68 is connected to the output end of the motor 66. The outer sides of both the adsorption turntable 65 and the rotating head 68 are provided with belt grooves for mounting the conveyor belt 67. The conveyor belt 67 is driven and connected in the belt grooves of the adsorption turntable 65 and the rotating head 68. The extracted gas is guided and transported by the air guide pipe 61 and the air guide fan 62. The extracted gas is further filtered by the filter screen 63. The adsorption turntable 65 is limited and supported by the limiting support frame 64. The adsorption turntable 65 is used to dehumidify the extracted air. The motor 66, the conveyor belt 67 and the rotating head 68 drive the adsorption turntable 65 to rotate, so that the entire surface of the adsorption turntable 65 can be evenly contacted with the extracted gas, thereby maximizing the adsorption of water vapor by the adsorption turntable 65.

[0038] The working principle of this utility model is as follows: When using this device, first check all valves to ensure that the pipe valve 25 on the vent pipe 21 is closed, the pipe valve 25 on the first suction pipe 22 is open, and the discharge valve 13 and the air pipe valve 43 are closed. After the check is completed, turn on the vacuum pump 7 to start suction. At this time, the suction gas passes through the air guide pipe 61, the air guide fan 62 and the filter screen 63 of the processing box 6, and is then guided to the adsorption turntable 65. The adsorption turntable 65 rotates and adsorbs the gas under the effect of the motor 66, the rotor 68 and the conveyor belt 67, thereby adsorbing and removing water vapor to the greatest extent. When the negative pressure inside the vacuum conveyor body 1 is large enough, use the feed port 14 on the feed pipe 11 to suck up the kitchen waste. After the suction is completed, turn off the vacuum pump 7, close the pipe valve 25 on the first suction pipe 22, open the pipe valve 25 on the air pipe 21, and open the discharge valve 13 to... The collected kitchen waste is discharged into the kitchen waste treatment device through the discharge port 12. After discharge, the discharge valve 13 is closed, the pipe valve 25 on the air pipe 21 is closed, and the air pipe valve 43 is opened. At this time, the high-pressure gas in the back-blowing air bag 42 will be sprayed out from the back-blowing air port 45 along the back-blowing air pipe 41 and the connecting air pipe 44. The gas sprayed out from the back-blowing air port 45 will drive the impeller 54 to rotate. The impeller 54 will drive the rotating shaft 53 and the cleaning rod 55 to rotate. When the cleaning rod 55 rotates, the cleaning brush 56 on the cleaning rod 55 will wash and clean the bottom of the multi-layer filter screen 24. At the same time, the gas blown out from the back-blowing air port 45 will be blown towards the multi-layer filter screen 24 under the guidance of the annular air guide plate 46, thereby blowing and cleaning the multi-layer filter screen 24. When the gas in the back-blowing air port 45 is discharged, the cleaning work is completed. The air pipe valve 43 is closed, the back-blowing air bag 42 is replaced, and the device is no longer in use.
