Description

Technical Field

[0001] The invention relates to the technical field of garbage cleaning, and in particular to a garbage cleaning device. Background Art

[0002] As people's environmental awareness increases, they pay more and more attention to the pollution-free and recyclable treatment of domestic waste. When the waste is sorted and recycled, it is necessary to clean the waste to remove the stains on it.

[0003] At present, the main methods for cleaning garbage are as follows: a cleaning pool is set up, water is passed into the cleaning pool, and the water in the cleaning pool is heated, and then the garbage is poured into the cleaning pool, and a stirring device or a rolling brush is used to push the garbage and clean the garbage. After the cleaning is completed, the stirring device or the rolling brush is turned off, and then the garbage is manually salvaged and the water contained in the cleaned garbage is drained.

[0004] In the above cleaning method, the garbage is scattered in the cleaning pool after cleaning, the efficiency of manual salvaging is extremely low, and the salvaging effect is poor. Some garbage will always remain in the cleaning pool after salvaging. When discharging the sewage in the cleaning pool, the remaining garbage may block the sewage pipe; at the same time, when salvaging the garbage, the container for the cleaned garbage can only be placed outside the cleaning pool, and the salvaged garbage will bring up the water in the cleaning pool, which will cause more water to drip on the ground outside the cleaning pool, causing the floor in the workshop to be slippery, making it easy for workers to slip, and some garbage may be left on the ground during salvaging, requiring workers to clean the ground after the salvage is completed. The surface of the garbage is cleaned, which greatly increases the labor intensity of the staff; in addition, the salvaged garbage still contains a lot of water, and the water contained in the garbage needs to be processed during subsequent treatment, which also increases the cost of garbage cleaning and reduces the efficiency of garbage cleaning; of course, since domestic garbage generally contains more grease, when cleaning, a lot of grease will float in the cleaning pool. When salvaging the garbage, the garbage will pass through the grease layer floating on the water surface, causing the cleaned garbage to be contaminated with a lot of grease again, resulting in a poor garbage cleaning effect. At the same time, when discharging sewage, the grease is discharged along with the sewage, which will also cause pollution to the environment. Summary of the invention

The opening directions of the third discharge port 401 and the third feed port are both vertically downward, and the height of the third discharge port 401 is higher than that of the third feed port. The third feed port is connected with the second discharge port 504. The garbage leaving the washing auger enters the discharge auger 4 through the third feed port, and the discharge auger 4 lifts the garbage and transports it to the third discharge port 401. A hopper is placed under the third discharge port 401 to collect the garbage at the conveying point of the discharge auger 4, eliminating the trouble of manual garbage salvage, and the garbage will not be scattered in the cleaning pool 1, so that the garbage collection is more comprehensive. The garbage entering the discharge auger 4 after cleaning contains more water. In order to reduce the amount of water contained in the garbage, the present embodiment is provided with a plurality of second water leakage holes 405 on the third shell 403, and an arc-shaped baffle 404 extending along the length direction of the shell is provided under the third shell 403. The arc-shaped baffle 404 is used to collect water flowing out of the second water leakage holes 405 to prevent it from dripping on the ground, and the arc-shaped baffle 404 is located between the third feed port and the third discharge port 401. The lower end of the arc-shaped baffle 404 extends into the cleaning pool 1 to send the water collected by the arc-shaped baffle 404 back to the cleaning pool 1, which can save water resources and keep the floor of the workshop dry and clean. At the same time, in order to facilitate the fixation of the arc baffle 404 and the discharging auger 4, a bracket connecting the arc baffle 404 and the cleaning pool 1 can also be provided on the side of the arc baffle 404 away from the shell, and the bracket includes vertical rods and horizontal rods connected to each other, the bottom and top of the vertical rods are fixedly connected to the arc baffle 404, and one end of the horizontal rod is fixedly connected to the side wall of the cleaning pool 1, wherein the brackets can be arranged in parallel in 2 or more groups to effectively support the arc baffle 404, and a number of support columns for supporting the shell can be arranged between the arc baffle 404 and the shell, the top of the support column is fixedly connected to the shell, and the bottom is fixedly connected to the arc baffle 404, the upper end of the discharging auger 4 is supported by the arc baffle 404, and the lower end of the discharging auger 4 is supported by the cleaning pool 1, specifically, some brackets can be arranged to connect the lower end of the discharging auger 4 with the cleaning pool 1.

[0040] At the same time, in order to separate the oil and water in the cleaning pool 1 during the cleaning process and discharge the grease out of the cleaning pool 1 to improve the cleaning effect of the garbage, an oil-water separator 6 can be arranged on one side of the cleaning pool 1. The oil-water separator 6 includes an oil removal tank 601 and an overflow tank 602 arranged on one side of the oil removal tank 601, wherein the upper end of the oil removal tank 601 is provided with a liquid inlet 603 connected to the cleaning pool 1. Since the density of grease is less than that of water, the grease will float on the water surface. At this time, the grease layer on the upper end of the cleaning pool 1 will The liquid enters the degreasing tank 601 from the liquid inlet 603, while the water at the lower end does not enter the degreasing tank 601, that is, it does not affect the cleaning of the garbage, and can reduce the grease content in the cleaning pool 1, so as to prevent the garbage after cleaning from being contaminated with grease from the cleaning pool 1, and the garbage becomes dirtier after being washed, that is, the garbage cleaning effect is improved, and an oil discharge port 604 is provided on the side of the degreasing tank 601 away from the liquid inlet 603, which is used to discharge the grease in the degreasing tank 601, so as to realize the real-time separation of oil and water and the real-time discharge of grease;

[0041] The overflow box 602 is used to store or discharge part of the water in the cleaning pool 1 when the liquid level in the cleaning pool 1 is too high. An isolation chamber 606 is arranged outside the overflow box 602. A water inlet connected to the inside of the isolation chamber 606 is arranged at the bottom of the isolation chamber 606. The position of the water inlet is lower than the position of the liquid inlet 603. The overflow box 602 is provided with an overflow port 605 connected to the isolation chamber 606 at the upper end. The setting height of the overflow port 605 is the same as the setting height of the liquid inlet 603. When there is a lot of water inside, the water in the lower layer enters the isolation chamber 606 from the water inlet, and enters the overflow box 602 from the overflow port 605, thereby assisting the oil removal tank 601 in oil-water separation, reducing the amount of water entering the oil removal tank 601, and increasing the speed of oil-water separation. At the same time, an overflow water outlet 607 is provided on one side of the overflow box 602, and the water in the overflow box 602 is led out by the overflow water outlet 607. A valve can be provided on the overflow water outlet 607, and when the water in the overflow box 602 reaches a certain amount, the water is led out again. Among them, the upper surface of the oil removal tank 601 and the overflow box 602 can be flush with the upper surface of the cleaning pool 1, and the upper surface of the liquid inlet 603 and the overflow port 605 is slightly lower than the upper surface of the cleaning pool 1. Since the cleaning pool 1 is generally filled with more water when cleaning garbage, the height of the oil removal tank 601 and the overflow box 602 is set in this way so as to achieve an excellent overflow and oil discharge effect.

[0042] In order to further improve the oil-water separation effect, a partition 608 can be set in the oil removal tank 601 to separate the oil removal tank 601 into a sedimentation chamber 609 and an oil discharge chamber 610. The height of the partition 608 is lower than the setting height of the liquid inlet 603 and the oil discharge port 604. The liquid inlet 603 is set on a side wall of the sedimentation chamber 609, and the upper end of the sedimentation chamber 609 is connected to the upper end of the oil discharge chamber 610. The sedimentation chamber 609 and the oil discharge chamber 610 are both provided with a liquid discharge port at the lower end. The oil discharge port 604 is set on the side wall of the oil discharge chamber 610. The liquid flows out from the liquid inlet After entering, 603 first enters the sedimentation chamber 609, and uses the sedimentation chamber 609 for buffering, so that water is deposited in the sedimentation chamber 609, and grease enters the oil discharge chamber 610 from above the partition 608. The water will further settle, and the grease will leave the oil removal tank 601 from the oil discharge port 604. When the water in the cleaning pool 1 needs to be replaced, the remaining liquid in the sedimentation chamber 609 and the oil discharge chamber 610 can be discharged from the drain port. Therefore, the drain port needs to be set near the bottom of the sedimentation chamber 609 and the oil discharge chamber 610, and a valve can be set at the drain port to control the opening and closing of the drain port.

[0043] Domestic garbage usually contains a lot of small particles, such as dust, rice grains, small particles of seasoning in vegetables, etc. These small particles will enter the cleaning pool 1 from the first leaking hole 502 and will be deposited at the bottom of the cleaning pool 1. If they are not treated, the organic matter contained in these small particles will emit a bad smell and breed bacteria, which will have an adverse effect on garbage cleaning. Therefore, in this embodiment, a bearing rod 8 assembly is arranged at the bottom of the cleaning pool 1, and the cleaning auger and the oil-water separator 6 are both arranged on the bearing rod 8 assembly, which can not only be effectively supported, but also prevent garbage cleaning.

The first bevel teeth 710 and the second bevel teeth 712 are staggered, and the staggered first bevel teeth 710 and the second bevel teeth 712 are used to scrape the small solid particles at the bottom of the cleaning pool 1 more comprehensively, and then the vertical plate 708 is used to push the small solid particles for cleaning, and a scraper can also be provided at the bottom of the vertical plate 708. The scraper and the bottom of the first bevel teeth 710 and the second bevel teeth 712 are on the same horizontal plane. The scraper can further scrape off the small solid particles at the bottom of the cleaning pool 1, thereby further improving the sewage discharge capacity of the cleaning pool 1.

[0045] In order to facilitate the discharge of the small solid particles pushed to one side of the cleaning pool 1 by the cleaning brush 701, a buffer groove can be provided at the bottom of the cleaning pool 1 on the side of the first cleaning plate 709 away from the vertical plate 708. The buffer groove is located at the edge of the cleaning pool 1 and is parallel to the cleaning brush 701, and the buffer groove is recessed toward the bottom of the cleaning pool 1. The sewage outlet is provided at one end of the buffer groove, and the bottom of the buffer groove is inclined toward the sewage outlet. When in use, the cleaning brush 701 pushes the small solid particles into the buffer groove, and the buffer groove is inclined. The loosened solid particles still contain some water, which makes them have better fluidity, that is, they will gradually slide along the bottom of the buffer groove to the sewage outlet and leave the cleaning pool 1 from the sewage outlet.

[0046] At the same time, in order to effectively heat and keep the water in the cleaning pool 1 warm and improve the degreasing effect of the cleaning pool 1, the heating device of the cleaning pool 1 is also improved, wherein a heating chamber 101 is arranged outside the cleaning pool 1, and a liquid heating medium is passed through the heating chamber 101. The liquid heating medium can be heat-conducting oil or water for conventional heating. A medium inlet 108 is arranged at the upper end of the heating chamber 101, and a medium outlet 107 is arranged at the lower end. The medium inlet 108 is used to pass the heating medium, and the medium outlet 107 is used to discharge the heating medium after heat exchange in the heating chamber 101. The heating medium is sent to the external heating device for heating and then sent to the heating chamber 101 again for The water in the cleaning pool 1 is heated or kept warm; a spiral coil 102 extending in the vertical direction is arranged in the heating chamber 101, and the spiral pipe is made of a material with good thermal conductivity, so that the heat exchange effect inside and outside the spiral coil 102 is better, and a water pump 103 is connected to the upper end of the spiral coil 102, and the water pump 103 is connected to an inlet pipe 104 with an end extending into the water pool, and the inlet pipe 104 is fixed on the side wall of the cleaning pool 11, that is, the inlet pipe 104 is located at the edge of the cleaning pool 1 to avoid the inlet pipe 104 affecting the garbage cleaning. The inlet pipe 104 can be connected through a perforated plate fixedly connected to the cleaning pool 1, and the water pump 103 passes the inlet pipe 104 to the upper part of the cleaning pool 1 The water in the spiral coil 102 can exchange heat with the heating medium in the heating chamber 101 to heat the water. In addition, since the cleaning pool 1 is large, the spiral coil 102 will meander for a long length, that is, the heat exchange between the water in the spiral coil 102 and the medium in the heating chamber 101 is more thorough. The lower end of the spiral coil 102 is provided with a drainage pipe for sending water into the cleaning pool 1. The cleaning pool 1 is provided with a drainage pipe connected to the drainage pipe. The bottom of the drainage pipe is fixedly connected to the bottom of the cleaning pool 1. The top of the drainage pipe is provided with a drainage port. The water in the spiral coil 102 that has undergone heat exchange with the heating medium passes through the drainage pipe and the drainage port. The water pipe enters the lower end of the cleaning pool 1 from the drain outlet, wherein the direction of the drain outlet can be set toward the middle of the cleaning pool 1, so that the water discharged from the drain outlet flows toward the middle of the cleaning pool 1, making the water temperature in the cleaning pool 1 more uniform, and at the same time, the top of the drain pipe can be bent, that is, the drain outlet is set toward the bottom of the cleaning pool 1, so that the hot water discharged from the spiral coil 102 can produce a certain impact force on the bottom of the cleaning pool 1, which can not only prevent the small solid particles falling during garbage cleaning from being deposited at the bottom of the cleaning pool 11, but also make the water receive the rebound force from the bottom of the cleaning pool 11, accelerate the flow speed of the water in the cleaning pool 1, and make the water temperature in the cleaning pool 1 more uniform. In addition, in order to prevent small solid particles in the cleaning pool 1 from entering the drain pipe and the water inlet pipe 104, a filter can be set at the mouth of the water inlet pipe 104 and the drain outlet to prevent the water pump 103 and the spiral coil 102 from being blocked.

[0047] Furthermore, in order to further enhance the heat transfer effect between the water in the spiral coil 102 and the heating medium, at least one coil support for supporting the spiral coil 102 is provided in the heating chamber 101. The coil support is evenly distributed in the heating chamber 101 to effectively support the spiral coil 102. The coil support includes a vertical orifice plate 106 and a plurality of transverse fixing plates 105 for fixing the vertical orifice plate 106 to the wall of the heating chamber 101. The vertical orifice plate 106 is evenly distributed with a plurality of mounting holes in the vertical direction. The hole positions cooperate with each other, the spiral coil 102 passes through the mounting holes in sequence and is supported by the mounting holes, one end of the fixing plate 105 is welded to the vertical hole plate 106, and the other end is welded to the cavity wall of the heating chamber 101, wherein the fixing plate 105 can be connected to the inner wall of the heating chamber 101, and can also be connected to the outer wall of the heating chamber 101. This arrangement allows the spiral coil 102 to contact the heating medium as much as possible, so that the heating medium and the water in the spiral coil 102 can have a more sufficient heat exchange, thereby improving the heating effect of the water.
