Description

Technical Field

[0001] This utility model relates to the technical field of kitchen waste treatment equipment, specifically to an integrated dehydration treatment device for kitchen waste treatment. Background Technology

[0002] Kitchen waste constitutes a large proportion of urban household waste, accounting for about 45% of the total weight. During storage, collection, transportation and disposal, kitchen waste is prone to rotting and emitting foul odors and attracting mosquitoes and flies in a short period of time due to its high moisture content and organic matter content, which poses a certain threat to the urban environment and people's health.

[0003] Urban waste is typically disposed of through incineration and landfill. If municipal solid waste is incinerated, the high moisture content (around 90%) and calorific value (around 2100-3000 KJ / kg) of food waste, combined with other waste, will not only fail to meet the calorific value requirements for waste-to-energy incineration but will also lead to incomplete combustion and the production of substances such as dioxins. Similarly, landfilling municipal solid waste is also problematic due to the high moisture content of the mixed food waste. Therefore, food waste needs to be dehydrated before disposal.

[0004] However, existing dehydration devices for food waste are not thorough enough during use, which affects the subsequent treatment effect of food waste; moreover, the waste cannot be disinfected during the dehydration process, and pathogens in the waste can easily spread, causing certain harm to human health and the natural environment. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides an integrated dehydration treatment device for kitchen waste processing.

[0006] The technical solution of this utility model is: an integrated dehydration treatment device for kitchen waste treatment, including a support frame, a dehydration component set on the upper end of the support frame, and a collection component set inside the support frame;

[0007] The dewatering assembly includes a dewatering cylinder mounted on the upper end of a support frame, a mesh cylinder fitted inside the dewatering cylinder, a rotating shaft rotatably engaged inside the mesh cylinder, a dewatering spiral mounted on the rotating shaft, and a dewatering motor mounted at the end of the dewatering cylinder and providing power to the rotating shaft; a feed hopper penetrating the mesh cylinder is provided on one side of the upper end of the dewatering cylinder; a water collection pipe is provided on the side of the lower end of the dewatering cylinder near the feed hopper, and a discharge pipe penetrating the mesh cylinder is provided on the side away from the feed hopper;

[0008] The collection assembly includes a sewage tank located inside one side of the support and connected to a water collection pipe, and a receiving tank located inside the other side of the support and connected to a discharge pipe; both the sewage tank and the receiving tank are movably fitted with a top cover, and both are equipped with a sewage discharge pipe on their side walls; an ultraviolet disinfection lamp is installed on the bottom surface of the top cover located at the top of the receiving tank.

[0009] Furthermore, a crushing disc is provided on the rotating shaft and on the side near the feed hopper;

[0010] Explanation: Using a shredder disc to shred the kitchen waste entering the mesh cylinder helps reduce the difficulty of dehydration under the squeezing action of the dehydration screw, thus improving the dehydration effect.

[0011] Furthermore, a filter screen is installed inside the sewage tank via a movable clip;

[0012] Note: Using a filter screen to perform secondary filtration of the water removed from kitchen waste helps improve the safety of kitchen waste wastewater discharge.

[0013] Furthermore, a centrifuge cylinder is rotatably engaged at the upper part of the receiving hopper, and a vertical shaft is installed through the centrifuge cylinder, with a first bevel gear at the bottom end of the vertical shaft; a centrifuge motor is installed on the side wall of the receiving hopper, and the output shaft of the centrifuge motor passes through the receiving hopper, with a second bevel gear meshing with the first bevel gear at the end of the output shaft.

[0014] Explanation: The centrifugal motor drives the vertical shaft to rotate, causing the centrifugal drum to rotate at high speed inside the receiving hopper. This process performs a secondary centrifugal dehydration treatment on the dehydrated kitchen waste, which helps to improve the thoroughness of dehydration and reduce the environmental harm caused by the dumping of kitchen waste.

[0015] Furthermore, the vertical shaft is rotatably engaged with the centrifuge cylinder, and a sleeve penetrating the top cover is slidably engaged on the vertical shaft. Stirring teeth are provided on the side wall of the sleeve. A compression spring and a rotating sleeve that abut against the compression spring and the upper end face of the top cover are respectively fitted on the outside of the sleeve. A docking chuck is fitted on the lower end of the side wall of the sleeve. A slot that can be movably engaged with the docking chuck is provided at the bottom of the receiving hopper. A push screw that abuts against the top of the sleeve is threadedly connected to the top of the top cover through a limit bracket.

[0016] Explanation: During the rotation of the vertical shaft, the centrifuge drum remains stationary, while the sleeve rotates with the vertical shaft, driving the stirring teeth to stir the dehydrated kitchen waste, thereby improving the thoroughness of the ultraviolet disinfection lamp for kitchen waste; the push screw pushes the sleeve to move downward along the vertical shaft, and finally makes the docking chuck engage and fix with the slot, at which point the vertical shaft drives the centrifuge drum to rotate.

[0017] Furthermore, ball bearings are rotatably engaged on the lower end face of the rotating sleeve and the bottom end of the pushing screw;

[0018] Note: By incorporating ball bearings on the rotating sleeve and the pushing screw, friction between them and the top cover and sleeve is reduced, thus reducing the power loss of the centrifugal motor and consequently lowering the energy consumption of this invention.

[0019] The method of using this utility model is as follows:

[0020] First, connect the dehydration motor, centrifugal motor, and ultraviolet disinfection lamp to an external power source. Feed the kitchen waste into the mesh cylinder through the feed hopper. The dehydration motor drives the rotating shaft to rotate, and the pulverizing disc cuts and pulverizes the kitchen waste. The dehydration spiral then squeezes and dehydrates the waste. The water in the waste enters the dehydration cylinder through the mesh cylinder and finally flows into the wastewater tank through the collection pipe. After squeezing and dehydration, the kitchen waste enters the centrifugal cylinder inside the receiving tank through the discharge pipe.

[0021] The centrifugal motor drives the vertical shaft and the sleeve to rotate. During the rotation of the sleeve, the stirring teeth rotate to stir the kitchen waste. The kitchen waste is then disinfected using an ultraviolet disinfection lamp. The push screw pushes the sleeve to move downward along the vertical shaft, and finally the docking chuck engages and is fixed with the slot. The sleeve drives the centrifugal cylinder to rotate, thus performing a secondary extrusion and dehydration treatment on the kitchen waste.

[0022] Compared with the prior art, the beneficial effects of this utility model are reflected in the following aspects:

[0023] First, the structure of this utility model is reasonably designed. It uses a dehydration spiral to squeeze and dehydrate kitchen waste, making the dehydration of kitchen waste more efficient and convenient. It uses an ultraviolet disinfection lamp to disinfect the dehydrated kitchen waste, avoiding the harm of pathogens in kitchen waste to the human body and the natural environment, and improving the safety of kitchen waste discharge.

[0024] Secondly, this invention utilizes a centrifuge drum to perform a secondary centrifugal dehydration treatment on the dehydrated kitchen waste, making the dehydration of the kitchen waste more thorough, which is conducive to the secondary utilization of kitchen waste and improves economic efficiency; at the same time, during the disinfection process of kitchen waste, the stirring teeth are used to stir the kitchen waste, which improves the uniformity and thoroughness of the disinfection of kitchen waste.

[0025] Third, this utility model utilizes a shredder disc to cut and shred kitchen waste, effectively reducing the difficulty of dehydrating kitchen waste and thus reducing the energy consumption of the device. Attached Figure Description
