Description

Technical Field

[0001] The invention belongs to the field of restaurant and kitchen waste treatment, and in particular relates to a treatment device for restaurant and kitchen waste. Background Art

[0002] With the development of the economy and the improvement of people's living standards, the discharge of kitchen waste is increasing. A large amount of kitchen waste has brought serious impacts on people's living environment and health. The Chinese government attaches great importance to the problem of garbage disposal, and the development of kitchen waste disposal machines is imperative.

[0003] Existing kitchen waste treatment machines are mainly divided into the following two types. The first is a microbial decomposition treatment machine, which uses organic microorganisms to degrade organic matter in kitchen waste and convert the residue into fertilizer. This treatment method better reflects the idea of ​​waste utilization, but there are also many problems in actual use. First, the salt content of compost is high, which is not conducive to the use of fertilizers. Secondly, due to process limitations, this type of kitchen waste treatment usually takes more than one day, which puts forward higher requirements for the deodorization and storage of the waste. Kitchen waste needs to be cleaned every day, and frequent opening of such devices will cause the indoor air environment to deteriorate.

[0004] The other type is a crushing type processor, which is usually installed under the sink and drives the blade through a small DC or AC motor. The food waste in the crushing chamber is crushed by centrifugal force and then directly discharged into the sewer. This treatment device is not suitable for large-scale promotion in China. This is because the crushed kitchen waste forms fine particles, which are easily deposited in the pipes, increasing the risk of pipe blockage. In addition, due to the dining habits of the Chinese, the oil content of kitchen waste is relatively high. When the oil encounters low temperature, it is easy to adhere to the pipe, which further increases the risk of pipe blockage. At the same time, when the crushing mechanism crushes the food, the large amount of water in the food waste will cause a lot of resistance, resulting in poor crushing effect. Summary of the invention

[0005] The object of the present invention is to provide a device for treating kitchen waste which has good crushing effect and can separate residue from oil and water.

[0006] In order to achieve the above-mentioned purpose, the present invention provides a device for processing kitchen waste, comprising a frame, a crushing mechanism and a motor, and also comprising a dry-wet separation mechanism, wherein the crushing mechanism, the dry-wet separation mechanism and the motor are fixed on the frame in sequence from top to bottom; the crushing mechanism comprises a crushing shell, a crushing knife and a feeding unit, wherein the number of the crushing knives is two, and the crushing knives are both rotatably arranged in the crushing shell, a transmission sprocket is arranged between the crushing knife and the motor, and the two crushing knives are vertically arranged; the feeding unit comprises a feeding bottom plate, a crank rocker mechanism, a baffle and a palladium claw, a plurality of strip holes are arranged on the feeding bottom plate, the crank rocker mechanism is arranged below the feeding bottom plate, and one end of the crank rocker mechanism is coaxially arranged with the crushing knife, and the other end is installed on the crushing shell, the palladium claw is fixed on the crank rocker mechanism, and each palladium claw corresponds to a strip hole; the baffle is fixed on the crushing shell, and a liquid outlet pipe is arranged at the lowest end of the crushing shell.

[0007] The principle of this scheme is: put the food waste into the feed bottom plate, the water in the food waste leaks out from the strip holes, and at the same time the crushing device is started, driving the connecting rod structure to move, and then driving the palladium claw to move, and the garbage in the feed bottom plate is transported to the crushing knife for physical crushing, and the crushed garbage enters the dry-wet separation mechanism. Under the action of the spiral conveying rod, the food waste gradually moves and compresses, and the liquid waste flows out of the liquid discharge port through the filter screen for collection. As the pressure of the solid waste increases, it overcomes the elastic force of the elastic part, so that the solid discharge port is opened, and the solid waste flows out of the solid discharge port for collection. The collected solid waste and liquid waste are further processed in the subsequent operation.

[0008] The beneficial effect of this solution is that compared with the traditional kitchen waste equipment, this solution places the usual crushing mechanism horizontally, and due to the arrangement of the strip holes, this solution can perform a water filtering operation before the garbage is crushed, which effectively reduces the crushing resistance during crushing and greatly improves the crushing effect. At the same time, the palladium claw can move back and forth in the strip holes, which can prevent the garbage from clogging the strip holes on the one hand, and also transport the garbage to the crushing mechanism on the other hand. The structure is unique and the effect is excellent. In addition, for relatively large / hard kitchen waste such as bones, ordinary crushing devices are easy to get stuck, but if the present solution gets stuck, since the feeding unit is tilted, it will retreat a distance, and then the palladium claw will push it to the crushing mechanism, and the adjustment of the position can effectively prevent the crushing device from getting stuck.

[0009] As one of the preferred schemes, the dry-wet separation mechanism includes a dry-wet separation shell and a spiral conveying rod, the spiral conveying rod is rotatably arranged in the dry-wet separation shell, the dry-wet separation shell is provided with a feed inlet at the top and a liquid discharge inlet at the bottom, the feed inlet of the dry-wet separation shell is located directly below the discharge inlet of the crushing shell; a filter is provided in the dry-wet separation shell, and the discharge inlet of the dry-wet separation shell is located below the filter; a solid discharge inlet is also provided at one end of the dry-wet separation shell; and it also includes a block for sealing the solid discharge inlet, a support plate is provided on the dry-wet separation shell, and an elastic member is provided between the support plate and the block; a transmission sprocket is provided between the spiral conveying rod and the motor.

[0010] The dry-wet separation mechanism and the crushing device of the present structure cooperate and can work with a single motor, which has a simple structure and effectively reduces the occupied space of the equipment. At the same time, the dry-wet separation mechanism can realize dry-wet separation very well, which is more environmentally friendly and hygienic.

[0011] As one of the preferred solutions, the dry-wet separation shell is provided with a spray port, and spraying can be performed at the spray port to enhance the separation effect.

[0012] As one of the preferred solutions, the filter screen is barrel-shaped. In addition to filtering the kitchen waste, the barrel-shaped filter screen can also filter the spray water.

[0013] As one of the preferred solutions, the solid discharge port is conical, and the stopper is a conical block matching the solid discharge port. The conical block has a simple matching structure and a good sealing effect.

[0014] As one of the preferred solutions, the filter holes of the filter screen are wedge-shaped mesh holes, which have better filtering effect.

[0015] As one of the preferred solutions, the filter screen is a stainless steel filter screen, which is not easy to rust and has a longer service life.

[0016] As one of the preferred solutions, the elastic member is a stainless steel spring, which is not easy to rust and has a longer service life.

[0017] As one of the preferred solutions, a support rod is provided between the support plate and the dry-wet separation shell. The provision of the support rod makes the support plate stronger and more stable.

[0018] As one of the preferred solutions, a collection box is provided below the liquid discharge port, the solid discharge port and the liquid discharge pipe. The setting of the collection box can conveniently collect the pre-processed garbage and facilitate subsequent operations.

[0019] As one of the preferred solutions, the crank-rocker mechanism is a plastic crank-rocker mechanism. The crank-rocker mechanism made of plastic will not rust, has good corrosion resistance and a long service life.

[0020] As one of the preferred solutions, the feed bottom plate is a magnetic feed bottom plate. If the kitchen waste contains metal impurities such as iron, it is easy to damage the crushing knife. The magnetic feed bottom plate can attract the magnet to the feed bottom plate to prevent damage to the crushing knife. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] This embodiment provides a device for processing kitchen waste, such as Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the whole device mainly includes three parts, which are a crushing mechanism 20, a dry-wet separation mechanism 30 and a motor 40 from bottom to top, and the three devices are all mounted on a frame 10. The motor 40 and the dry-wet separation mechanism 30 share one motor 40 and are driven by a chain, which can effectively optimize the structure and reduce the space occupancy.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, the crushing mechanism 20 includes a crushing shell and a group of crushing knives. The feed port 308 of the crushing shell is in the shape of a trumpet that expands outward to facilitate the placement of garbage. The feed top plate 23 on the top of the crushing shell does not need to be welded, and a hinged setting is better, so that the moisture in the garbage can be pressed out by rotating the feed top plate 23, and the effect is better. At the same time, the hinged feed top plate can also achieve a certain degree of sealing, which is more environmentally friendly. A group of crushing knives includes blades, two blades are staggered, and one end of the two blades is provided with gears that mesh with each other. The blade includes a plurality of cutter discs and cutter disc spacer rings. The assembly form of the driving shaft is 1 cutter disc and 1 cutter disc spacer ring, and several are assembled in sequence; the assembly form of the driven shaft is 1 cutter disc spacer ring and 1 cutter disc, and several are assembled in sequence (the same number as the assembly number of the driving shaft). A sprocket 303 is provided on the rotating shaft of one of the blades, and the sprocket 303 is connected to the sprocket 303 on the motor 40 through a transmission chain. The motor 40 is driven by 380V three-phase electricity, with a rated power of 3.7kw, and a workload of about 2 cubic meters per hour.

[0031] It is worth noting that in order to reduce the resistance of crushing, the crushing mechanism 20 is horizontally placed. Figure 6 As shown, a feed unit is arranged in the crushing shell. The feed unit includes a feed bottom plate 26, a crank rocker mechanism, a baffle 21 and a palladium claw 25. A plurality of strip holes are arranged on the feed bottom plate 26. The crank rocker mechanism is arranged below the feed bottom plate 26, and the left end of the crank rocker mechanism is arranged coaxially with the crushing knife, and the other end is mounted on the crushing shell. The palladium claw 25 is fixed on the crank rocker mechanism, and the top of the palladium claw 25 is slightly arc-shaped, and each palladium claw 25 corresponds to a strip. The baffle 21 is fixed on the crushing shell, and a liquid outlet pipe 22 is arranged below the rightmost end of the crushing shell. Generally speaking, the crank rocker mechanism can be set to plastic, preferably PVC. The crank rocker mechanism made of plastic will not rust, has good corrosion resistance, and has a long service life.

[0032] The lower left side of the crushing shell is the discharge port, and directly below the discharge port of the crushing shell is the feed port 308 of the dry-wet separation mechanism 30. Figure 5 As shown, the dry-wet separation mechanism 30 includes, from left to right, a spiral conveying rod 302 , a sprocket 303 , a dry-wet separation shell 301 , a conical stopper 306 , an elastic member 307 and a support plate 304 .

[0033] The leftmost end of the dry-wet separation shell 301 and the support plate 304 are both provided with bearings, and the screw conveying rod 302 is rotatably arranged in the dry-wet separation shell 301 through these two bearings. The sprocket 303 is fixed to the leftmost end of the screw conveying rod 302 and is connected to the sprocket 303 on the motor 40 through a transmission chain.

[0034] A feed port 308 and three spray ports 310 are provided above the dry-wet separation shell 301, and a liquid discharge port 309 is provided at the lower right side. The solid discharge port 305 is provided at the right end of the dry-wet separation shell 301, which is conical and has a conical stopper 306 correspondingly provided. A through hole is provided in the middle of the stopper 306, which is slightly larger than the spiral conveying rod. The stopper 306 is connected to the support plate 304 through an elastic member 307. In order to increase its service life, the elastic member 307 is made of a stainless steel spring. Figure 1 As shown, three support rods are further provided between the support plate 304 and the dry-wet separation shell 301 to increase the stability of the device.

[0035] A barrel-shaped filter cartridge is provided inside the dry-wet separation shell 301. The mesh of the filter cartridge is designed as a wedge-shaped mesh and is made of stainless steel. Of course, in order to facilitate the collection of separated solid waste and liquid waste, a collection box is also provided below the liquid discharge port 309, the solid discharge port 305 and the liquid discharge pipe 22.

[0036] During specific operation, the food waste is put into the feed bottom plate 26, and the water in the food waste leaks from the strip holes. At the same time, the crushing device is started, driving the connecting rod structure to move, and then driving the palladium claw 25 to move, and the waste in the feed bottom plate 26 is transported to the crushing knife for physical crushing. The crushed waste enters the dry-wet separation mechanism 30. Under the action of the spiral conveying rod 302, the food waste gradually moves and is compressed, and the liquid waste flows out of the liquid discharge port 309 through the filter screen 311 for collection. As the pressure of the solid waste increases, it overcomes the elastic force of the elastic member 307, so that the solid discharge port 305 is opened, and the solid waste flows out of the solid discharge port 305 for collection. The collected solid waste and liquid waste are further processed in the subsequent operation.

[0037] Compared with the traditional kitchen waste equipment, the present invention places the usual crushing mechanism 20 horizontally, and due to the arrangement of the strip-shaped holes, the present invention can perform a water filtering operation before the garbage is crushed, which effectively reduces the crushing resistance during crushing and greatly improves the crushing effect. At the same time, the palladium claw 25 can move back and forth in the strip-shaped holes, which can prevent the garbage from clogging the strip-shaped holes on the one hand, and also transport the garbage to the crushing mechanism on the other hand, with a unique structure and excellent effect.

[0038] It should be noted in advance that, in the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements.
