Description

Technical Field

[0001] The utility model relates to the field of kitchen waste treatment equipment, in particular to a kitchen waste recycling and treatment equipment. Background Art

[0002] Swill refers to leftovers or food residues discarded by people in hotels, restaurants, schools, and company canteens. Discarding swill at will will cause great harm to the environment. Swill also has recycling value because its liquid components contain a lot of animal and plant oils. If it is discharged directly, it will not only pollute the environment and block the sewers, but also cause waste of resources. Currently, the most reasonable and effective way to recycle swill is to collect the swill and treat it with microorganisms to decompose it into harmless carbon dioxide, water, and bioheat energy, etc. However, when the soup in the swill is mixed with the food and fermented with microorganisms, the soup will easily dilute the microbial flora, resulting in a poor fermentation effect. Utility Model Content

[0003] Based on this, it is necessary to provide a kind of kitchen waste water recycling and treatment equipment which can reduce the solid water content and volume in the waste water and facilitate the subsequent fermentation in order to solve the above-mentioned technical problems.

[0004] The utility model provides a kitchen waste water recycling and processing device, comprising:

[0005] The frame has a receiving cavity for receiving the liquid in the swill;

[0006] A transmission assembly is arranged on the frame, comprising a conveyor belt, a transmission roller and a first motor, wherein the conveyor belt is arranged obliquely relative to the ground;

[0007] A recovery box, fixed to the frame and located below the conveyor belt travel terminal;

[0008] An extrusion assembly is fixed on the frame, comprising a filter cartridge, an extrusion rod and a second motor, the recovery box is communicated with the filter cartridge, the extrusion rod is installed in the filter cartridge, and the second motor is installed on the filter cartridge and is in transmission connection with the extrusion rod;

[0009] The extrusion rod is a variable pitch, variable diameter screw, and the closer to the end of the filter cartridge, the smaller the pitch and the larger the diameter.

[0010] In one embodiment, the inner wall of the filter cartridge is provided with gauze.

[0011] In one of the embodiments, a delivery pipe is fixedly connected between the filter cartridge and the frame, and one end of the delivery pipe facing away from the filter cartridge extends into the accommodating cavity.

[0012] In one embodiment, a liquid outlet is provided on the cavity wall of the accommodating cavity, and the diameter of the liquid outlet is larger than the diameter of the delivery tube.

[0013] In one of the embodiments, the conveyor belt surface has a stopper.

[0014] In one embodiment, grooves are provided on both sides of the conveyor belt along the circumference direction, and small holes are provided on the bottom surfaces of the grooves.

[0015] In one of the embodiments, the height of the center position of the conveyor belt is higher than the groove and smoothly transitions to the groove.

[0016] In one of the embodiments, gears are fixedly mounted on both ends of the transmission roller, and teeth of the gears are embedded in the small holes.

[0017] The above-mentioned kitchen waste recycling and processing equipment uses an inclined conveyor belt to allow the liquid in the waste to fall directly into the containing cavity in the frame under the action of gravity and be discharged, and the solids in the waste are conveyed to the recovery box to achieve preliminary solid-liquid separation. Driven by the second motor, the extrusion rod rotates to push the solids to both ends. As the pitch on the extrusion rod becomes smaller and the diameter becomes larger, the gap between the extrusion rod and the inner wall of the filter cartridge continues to decrease, and the extrusion force continues to increase.

[0030] Swill is the food and beverage waste that is left over after a meal in a restaurant or family. It is also called catering waste, which is the food waste left over from human life. Discarding swill at will will cause great harm to the environment. Nowadays, hotels, canteens, and restaurants will produce a large amount of swill, which is usually poured into swill buckets for recycling and then harmlessly decomposed by microorganisms. Since the solids in swill are usually large in volume and high in water content, they are not easy to react with microbial fillers and are easy to dilute the bacterial flora, resulting in a decrease in reaction force. Therefore, solid-liquid separation is the first and most important step in swill treatment.

[0031] In view of the above problems, the utility model provides a kitchen waste water recovery and treatment device.

[0032] Combine the following Figure 1-Figure 4 The utility model describes the kitchen waste water recycling and processing equipment.

[0033] like Figure 1 As shown, in one embodiment, a kitchen waste recycling and processing device includes: a frame 100, a transmission assembly 200, a recycling box 300 and an extrusion assembly 400.

[0034] The frame 100 is in an inverted trapezoidal shape with one side lower than the other side, and has a receiving chamber 110 for receiving liquid in swill. The transmission assembly 200 is arranged on the frame 100, and includes a conveyor belt 210, a transmission roller 220 and a first motor 230. There are two transmission rollers 220, which are rotatably mounted on the high and low sides of the frame 100, respectively. The first motor 230 is fixedly mounted on the higher side of the frame 100 and connected to the transmission roller 220 on the same side. The conveyor belt 210 is tensioned on the two transmission rollers 220 and rotates under the drive of the first motor 230. The recovery box 300 is fixed on the frame 100 and is located below the travel terminal of the conveyor belt 210, and is used to receive solids in swill. The extrusion assembly 400 is fixed on the frame 100, including a filter cartridge 410, an extrusion rod 420 and a second motor 430. The recovery box 300 is connected to the filter cartridge 410, the extrusion rod 420 is installed in the filter cartridge 410, and the second motor 430 is installed on the filter cartridge 410 and is in transmission connection with the extrusion rod 420. Figure 2 .

[0035] Specifically, the extrusion rod 420 is a screw rod with variable pitch and variable diameter, and the pitch is smaller and the diameter is larger closer to the end of the filter cylinder 410.

[0036] In the operation process of the kitchen waste recycling and treatment equipment of this embodiment, the first motor 230 drives the transmission roller 220 to drive the conveyor belt 210 to rotate. Under the action of gravity, the liquid inside the kitchen waste located on the conveyor belt 210 directly falls into the accommodation cavity 110 in the frame 100 for discharge, and the solid inside it is conveyed into the recycling box 300, realizing preliminary solid-liquid separation. The solid located in the recycling box 300 then enters the filter cylinder 410. Driven by the second motor 430, the extrusion rod 420 rotates to push the solid towards both ends. As the pitch of the extrusion rod 420 becomes smaller and the diameter becomes larger, the gap between the extrusion rod 420 and the inner wall of the filter cylinder 410 continuously decreases, and the extrusion pressure continuously increases. The solid in the kitchen waste is physically extruded to achieve the purpose of reducing the water content and volume.

[0037] When the solid in the kitchen waste is extruded by the extrusion rod 420, it is easy to be extruded out from the holes of the filter cylinder 410, causing blockage. Therefore, a gauze 440 is arranged on the inner wall of the filter cylinder 410. The gauze 440 is fixed to the inside of the filter cylinder 410 by pasting. While reducing the aperture of the filter cylinder 410, it does not prevent the outflow of the extruded liquid. At the same time, it is convenient to disassemble and clean the gauze 440 by pasting, reducing the generation of peculiar smell.

[0038] In order to prevent the liquid extruded from being discharged randomly and causing pollution, a delivery pipe 450 is fixedly connected between the filter cylinder 410 and the frame 100. One end of the delivery pipe 450背离 the filter cylinder 410 extends into the accommodation cavity 110. In this way, the liquid can directly flow into the accommodation cavity 110 to be mixed with the liquid originally in the kitchen waste for discharge. At the same time, in order to further reduce the peculiar smell during discharge, a liquid outlet 111 is provided on the cavity wall of the accommodation cavity 110. The diameter of the liquid outlet 111 is larger than the diameter of the delivery pipe 450. In this way, too much kitchen waste liquid in the accommodation cavity 110 has not had time to be stored and has already been discharged.

[0039] As Figure 3 shown, in one embodiment, the surface of the conveyor belt 210 has a retaining platform 212, and an accommodation unit is formed between adjacent retaining platforms 212. In this way, it is avoided that the solid in the kitchen waste slides down under the influence of the inclination angle of the conveyor belt 210. And both sides of the conveyor belt 210 have grooves 214 along the circumferential direction. The bottom surface of the groove of the groove 214 has small holes 216. The height of the center position of the conveyor belt 210 is higher than that of the groove 214 and gently transitions towards the groove 214. Refer to Figure 4 。

[0040] After the swill comes into contact with the central position of the conveyor belt 210, it is affected by the uneven surface and forms a relatively loose situation. The internal liquid can also flow towards the concave part along the trend and converge into the groove 214 and fall from the small hole 216. At this time, some fine solids will also flow into the small hole 216 along with the liquid and cause blockage. Therefore, gears 221 are fixedly installed at both ends of the driving roller 220, and the teeth of the gears 221 are embedded in the small hole 216. In this way, on the one hand, the teeth of the gears 221 can convey the solids embedded in the small hole 216; on the other hand, since there is a lot of oil in the swill, the contact surface between the conveyor belt 210 and the driving roller 220 is prone to slipping. The addition of the gears 221 further limits the movement of the conveyor belt 210.

[0041] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0042] The above-described embodiments only represent several implementation manners of the present invention, and the description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
