Description

Technical Field

[0001] This utility model relates to the field of pressing device technology, and in particular to a mobile waste pressing device. Background Technology

[0002] Garbage presses primarily utilize the squeezing force generated by a rotating screw shaft within a cylindrical casing to expel water and grease from the garbage, achieving solid-liquid separation. The screw shaft, driven by a motor, has spiral blades on its surface. As the screw shaft rotates, the blades propel the garbage forward and compress it, simultaneously squeezing out water and grease. During compression, the squeezed-out water and grease mixture is discharged through a specific drain port. To achieve oil-water separation, an oil-water separator is typically installed at the drain port. The oil-water separator uses the principle of density difference between oil and water to separate the grease and water. The separated grease can be further refined into biodiesel or other chemical products, while the water can be used to rinse equipment or undergo other treatments. Solid waste processed by the screw press is significantly reduced in volume and has a much lower grease content. This solid waste can be further utilized for resource recovery, such as as fertilizer, feed, or biomass energy. Furthermore, to reduce environmental pollution and waste disposal costs, solid waste can also be composted or incinerated.

[0003] Common garbage presses mainly rely on the thrust generated by the rotation of the spiral blades to compress garbage. The compression force is relatively small. If it encounters hard or large pieces of garbage, it is difficult to squeeze out the oil and water inside. The volume of garbage shrinks little, which is not conducive to the dry and wet separation of garbage. Utility Model Content

[0004] The main purpose of this utility model is to provide a mobile garbage pressing device to solve the problems mentioned in the related technology that the commonly used garbage press has low compression force, and it is difficult to press out the oil and water inside the hard or large garbage, resulting in little shrinkage of the garbage volume and making it unfavorable for dry and wet separation of garbage.

[0005] To achieve the above objectives, according to one aspect of the present invention, a mobile garbage pressing device is provided, comprising: a pressing box for storing garbage, the pressing box being provided with a plurality of casters, the casters facilitating the movement of the pressing box when they roll.

[0006] The pressing section is located inside the pressing box and presses the waste inside the pressing box. When the pressing section is working, it presses out the water and oil from the waste and discharges it from the bottom of the pressing box. The high-density waste after pressing is discharged from the rear of the pressing box.

[0007] Furthermore, the pressing box also includes a box body, a feed inlet, a slag outlet, a liquid outlet, and several support legs. The support legs are all fixedly installed at the bottom of the box body to support the box body, and each support leg is fixedly equipped with a caster wheel at its bottom.

[0008] Furthermore, the feed inlet is fixedly located on the front side of the upper part of the box, and the waste is fed into the box through the feed inlet. The liquid outlet is fixedly located on the rear side of the lower part of the box, and a filter screen is fixedly installed above the liquid outlet to block the solid waste above the liquid outlet. The slag outlet is fixedly located at the rear of the box, and the pressed waste is discharged from the slag outlet.

[0009] Furthermore, the pressing section includes a rotating shaft, a power source, a spiral body, and several cutting blades. The rotating shaft passes through the interior of the housing and can rotate along the housing. The power source is fixedly located on the outer side of the front end of the housing and is fixedly connected to one end of the rotating shaft to drive the rotating shaft to rotate.

[0010] Furthermore, the spiral body is fixedly mounted on the outer ring of the rotating shaft. The diameter and spacing of the spiral bodies are unequal. The diameter of the spiral body at the end closer to the power source is larger than the diameter at the other end, and the spacing of the spiral body at the end closer to the power source is larger than the spacing at the other end.

[0011] Furthermore, the cutting blades are all fixedly mounted on the surface of the spiral body for cutting the debris between the spiral bodies.

[0012] Furthermore, the cutting blade is symmetrical on both sides, and each side of the cutting blade includes a blade body, a blade head, serrations, several horizontal grooves and vertical grooves.

[0013] Furthermore, the chip head is fixedly disposed at one end of the chip body, the serrations are fixedly disposed on the outer side of the chip head, the transverse grooves are all disposed on the side of the chip body and slope downward from front to back, and the vertical groove is disposed at the tail of the side of the chip body and communicates with the transverse grooves.

[0014] Compared with the prior art, this utility model has the following beneficial effects: the diameter and pitch of the spiral at the feed inlet end are both large, and a large amount of waste is conveyed in one rotation of the shaft. The diameter and pitch of the spiral near the slag outlet end are both small, and the waste conveyed from the front end cannot be discharged in time. The waste accumulates and is pressed at the tail of the box to squeeze out the water and oil. After being discharged from the liquid outlet, it is centrally processed. The density of the pressed waste increases and it is discharged from the slag outlet, completing the dry and wet separation. The sharp serrations can easily penetrate into the hard, large pieces of waste and break them. The blades cut the large pieces of waste, making it easier for the spiral to thoroughly press the waste and squeeze out the water and oil. The pressed water and oil flow forward along the horizontal groove, collect at the vertical groove and flow downward, falling into the box and then being discharged from the liquid outlet.

[0023] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0024] Please see Figures 1 to 5 This embodiment provides a mobile garbage pressing device, including: a pressing box 1, which is used to store garbage. The pressing box 1 is provided with a number of casters 16, which can facilitate the movement of the pressing box 1 when the casters 16 are rolling.

[0025] The pressing section 2 is located inside the pressing box 1 and presses the waste inside the pressing box 1. When the pressing section 2 is working, it presses out the water and oil from the waste and discharges it from the bottom of the pressing box 1. The high-density waste after pressing is discharged from the rear of the pressing box 1.

[0026] The pressing box 1 also includes a box body 11, a feed inlet 12, a slag outlet 13, a liquid outlet 14, and several support legs 15. The support legs 15 are all fixedly installed at the bottom of the box body 11. In this embodiment, four support legs 15 are preferred to stably support the box body 11. Each support leg 15 is fixedly provided with a caster wheel 16 at its bottom. In this embodiment, four caster wheels 16 are preferred, which are equal in number to the support legs 15, to facilitate the movement of the pressing box 1.

[0027] The feed inlet 12 is fixedly located on the front side of the upper part of the box body 11. Waste is fed into the box body 11 through the feed inlet 12. The liquid outlet 14 is fixedly located on the rear side of the lower part of the box body 11. A filter screen is fixedly installed above the liquid outlet 14 to block solid waste above the liquid outlet 14, preventing waste from being discharged from the liquid outlet 14 and thus making it impossible to complete the dry and wet separation of waste. The slag outlet 13 is fixedly located at the rear of the box body 11. The pressed waste is discharged from the slag outlet 13.

[0028] The pressing section 2 includes a rotating shaft 21, a power source 22, a spiral body 23, and several cutting blades 24. The rotating shaft 21 passes through the interior of the housing 11 and can rotate along the housing 11. The power source 22 is fixedly located on the outer side of the front end of the housing 11. In this embodiment, a motor is preferred as the power source 22 for easy operation. The power source 22 is fixedly connected to one end of the rotating shaft 21 to drive the rotating shaft 21 to rotate.

[0029] The spiral 23 is fixed on the outer ring of the rotating shaft 21. The diameter and spacing of the spiral 23 are different. The diameter of the spiral 23 at the end near the power source 22 is larger than that at the other end. The spacing of the spiral 23 at the end near the power source 22 is larger than that at the other end. When the rotating shaft 21 rotates once, more waste is transported at the front end of the box 11. The waste at the tail end of the box 11 cannot be discharged in time. It accumulates and is pressed at the tail end of the box 11 to squeeze out the water and oil. After being discharged from the liquid outlet 14, it is centrally processed. The density of the pressed waste increases and it is discharged from the slag outlet 13, thus completing the dry and wet separation of the waste.

[0030] The cutting blades 24 are all fixed on the surface of the spiral body 23 to cut the waste between the spiral bodies 23, cutting hard, large pieces of waste into smaller pieces so that the spiral body 23 can thoroughly press them.

[0031] The cutting blade 24 is symmetrical on both sides. Each cutting blade 24 includes a blade body 241, a blade head 242, serrations 243, several horizontal grooves 244 and vertical grooves 245. The symmetrical cutting blade 24 makes it easier to cut up the waste.

[0032] The chip head 242 is fixedly installed at one end of the chip body 241, the serrations 243 are fixedly installed on the outside of the chip head 242, the transverse grooves 244 are all installed on the side of the chip body 241 and slope downward from front to back, the vertical groove 245 is installed at the rear of the side of the chip body 241 and communicates with the transverse grooves 244. The serrations 243 cut the waste, and the water and oil squeezed out of the waste flow backward along the transverse grooves 244, collect in the vertical grooves 245 and fall to the bottom of the box 11, and finally discharge from the liquid outlet 14.

[0033] Waste is fed into the housing 11 through the feed inlet 12, falling onto the rotating shaft 21 and the screw 23. The power source 22 is started, driving the rotating shaft 21 to rotate, which in turn drives the screw 23 to rotate, transporting the waste from the housing 11 towards the discharge outlet 13. Because the diameter and pitch of the screw 23 at the feed inlet 12 are larger, a greater amount of waste is transported in one rotation of the rotating shaft 21. However, the diameter and pitch of the screw 23 near the discharge outlet 13 are smaller, making it impossible to discharge the waste from the front end in a timely manner. The waste accumulates and is pressed at the rear of the housing 11. Moisture and oil are pressed out and discharged from the liquid outlet 14 for centralized processing. The density of the pressed waste increases and it is discharged from the residue outlet 13, completing the dry and wet separation. When the waste is conveyed and pressed between the spiral bodies 23, the sharp serrations 243 can easily penetrate into the hard, large pieces of waste and break them. The blades 242 cut the large pieces of waste, making it easier for the spiral bodies 23 to thoroughly press the waste, pressing out the moisture and oil. The pressed moisture and oil flow forward along the horizontal groove 244, collect at the vertical groove 245 and flow downward, falling into the box 11, and then being discharged from the liquid outlet 14.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
