Description

Automatic cutting, crushing and screening equipment for kitchen waste treatment Technical Field

[0001] The present invention relates to the technical field of environmental protection, and in particular to an automatic cutting, crushing and screening device for treating kitchen waste. Background Art

[0002] Kitchen waste often contains plastic bottles, large bones, chopsticks, and other long or round objects. These materials often cannot be shredded properly and can cause shredder failures. Alternatively, large pieces of material and long fibers can be mixed in with the material, affecting the drying process. To address this, traditional methods generally rely on manual sorting. This wastes a lot of manpower and resources, and the sorting results vary from person to person, making them difficult to guarantee.

[0003] Summary of the Invention

[0004] The present invention provides an automatic cutting, crushing and screening device for treating kitchen waste to solve the above-mentioned deficiencies in the prior art.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] An automatic cutting, pulverizing, and screening device for treating food waste includes a variable-frequency, adjustable-speed power mechanism with a spiral pulverizing paddle fixedly connected to its output shaft. The pulverizing paddle comprises two rotating shafts, with two propeller blades fixedly attached to the exterior of each shaft. The propeller blades are provided with multiple through-holes, and a feed scraper fixedly connected to one side of the propeller blades. The propeller blades are formed from alloy steel by heat processing, resulting in high strength and wear resistance. The outer edge of the spiral is finely machined to form a sharp edge, maintaining a small gap with the cylinder and creating a narrow space between the filter holes below, thereby achieving the cutting and pulverizing function. The through-holes evenly distributed on the paddle blades serve to retain and fully stir the material. Furthermore, the material, under the action of the propeller blades, continuously tumbles, collides, and rubs against each other, also crushing the material. The propeller blades are themselves a group of auger blades with uniform pitch when they are manufactured. When they cooperate with the outer cylinder, the power transmitted by the variable frequency speed-adjustable power mechanism drives the propeller blades to rotate at high speed, thereby fully crushing the material. The wind pressure generated by the high-speed rotation of the propeller blades will also blow lighter debris such as plastic bags to the end. The propeller blades continuously push forward, and discharge large-particle solid materials and fibers, plastic bags and other materials from the bulk material outlet set at the end of the cylinder into the recycling bin, thereby realizing automatic screening function. The external rotation of the two rotating shafts is connected to the cylinder, and two observation windows are provided on the top of the cylinder, which can also be used as maintenance windows. A filter hole is provided at the bottom of the cylinder, and the filter hole is expanded from the outer end to form a tapered hole, which is convenient for unloading and not easy to be blocked and left over. A bulk material outlet is provided on one side of the cylinder, and the taper design of the bulk material outlet ensures smooth feeding and prevents backflow.

[0007] Preferably, a cover plate is hinged on the top of the cylinder, and the top of the cylinder is connected to a backwash joint.

[0008] Preferably, a discharge hopper is fixed at the bottom of the cylinder, the filter hole is connected to the discharge hopper, and a bulk material discharge hopper is fixed on one side of the cylinder, and the bulk material discharge hopper is connected to the bulk material outlet.

[0009] Preferably, one end of the cylinder is fixedly connected to a support frame, and two limit plates are fixed on the top of the support frame on one side. Feed ports are opened through the surfaces of the two limit plates, and a plug valve is provided inside the two limit plates.

[0010] Preferably, a plug-in valve port is provided at the top of the bulk material outlet, and a second plug-in valve is sleeved inside the plug-in valve port.

[0011] Preferably, the edge of the propeller blade close to the inner wall of the cylinder is provided with a cutting edge.

[0012] Preferably, the backwash connector is externally connected to a water supply pump.

[0013] Compared with the existing technology, the beneficial effects of the present invention are:

[0014] The whole machine integrates automatic crushing, cutting and screening by cooperating with the multifunctional propeller blades on the rotating shaft and the inner cylinder and other components. The multifunctional propeller blades are formed by heat processing of alloy steel and are evenly distributed with multiple through holes. After heat treatment, the blades have high strength and high wear resistance. The outer edge of the spiral is finely processed to form a sharp edge, and the narrow space formed between the filter holes of the inner cylinder achieves the cutting and crushing function. The multiple through holes evenly arranged on the multifunctional propeller blades make the crushing of materials more sufficient and thorough. The spatial distortion of the multifunctional propeller blades becomes the spiral auger blades. , it can automatically push the material forward when working. The wind pressure generated by the high-speed rotation of the multifunctional propeller blades blows plastic bags and other lighter debris to the end. The multifunctional propeller blades continuously push forward, and large particles of solid materials and fibers, plastic bags and other materials are discharged into the recovery bucket from the large material outlet set at the end of the cylinder, thereby realizing automatic screening function. The feed port is tapered to ensure smooth feeding and prevent backflow. The filter hole is expanded from the outer end to form a taper, which is convenient for feeding. The material is not prone to clogging and residue. The backwash interface design makes it easy to keep the equipment clean and will not produce odor due to material deterioration.

[0025] Example 1: Referring to Figures 1-6, an automatic cutting, pulverizing, and screening device for treating food waste comprises a variable-frequency, adjustable-speed power mechanism 1. A spiral pulverizing paddle 13 is fixedly connected to the output shaft end of the variable-frequency, adjustable-speed power mechanism 1. The spiral pulverizing paddle 13 comprises two rotating shafts 1301, with two propeller blades 1302 fixed to the exterior of the two rotating shafts 1301. The propeller blades 1302 are provided with a plurality of through-holes 1303. A feed scraper 1304 is fixedly connected to one side of the propeller blades 1302. The propeller blades 1302 are formed from alloy steel by heat treatment. After heat treatment, the propeller blades have high strength and wear resistance. The outer edges of the spirals are finely machined to form sharp edges, maintaining a small gap with the cylinder 4 and creating a narrow space between the filter holes 2 below, thereby achieving a cutting and pulverizing function. The through-holes 1303 evenly distributed on the propeller blades serve to retain and fully agitate the material. Furthermore, under the action of the propeller blades 1302, the material continuously tumbles, collides, and rubs against each other, thereby crushing the material. The propeller blades 1302 are themselves a group of auger blades with uniform pitch when they are manufactured. When they cooperate with the outer cylinder, the power transmitted by the variable frequency speed adjustable power mechanism 1 drives the propeller blades 1302 to rotate at high speed, thereby fully crushing the material. The wind pressure generated by the high-speed rotation of the propeller blades 1302 will also blow lighter debris such as plastic bags to move to the end. The propeller blades 1302 continuously push forward, and large particles of solid materials and fibers, plastic bags and other materials are discharged into the recycling bin from the bulk material outlet 15 set at the end of the cylinder, thereby realizing automatic screening function. The outer rotation of the two rotating shafts 1301 is connected to the cylinder 4. Two observation windows 14 are provided on the top of the cylinder 4. This observation window can also be used as an inspection window. A filtering hole 2 is provided at the bottom of the cylinder 4. The filtering hole is expanded from the outer end to form a tapered hole, which is convenient for material discharge and not easy to be blocked and left. A bulk material outlet 15 is provided on one side of the cylinder 4. The taper design of the bulk material outlet ensures smooth feeding and prevents backflow.

[0026] A cover plate 5 is hinged on the top of the cylinder 4, and a backwash connector 6 is connected to the top of the cylinder 4;

[0027] A discharge hopper 10 is fixed at the bottom of the cylinder 4, and the filter hole 2 is connected to the discharge hopper 10. A bulk material discharge hopper 11 is fixed on one side of the cylinder 4, and the bulk material discharge hopper 11 is connected to the bulk material outlet 15;

[0028] One end of the cylinder 4 is fixedly connected to a support frame 3, and two limit plates 7 are fixed on the top of the support frame 3 on one side. The surfaces of the two limit plates 7 are penetrated by a feed port 9, and the interiors of the two limit plates 7 are sleeved with a plug valve 12;

[0029] A gate valve port is provided at the top of the bulk material outlet 15, and a gate valve 2 8 is sleeved inside the gate valve port;

[0030] The edge of the propeller blade 1302 near the inner wall of the cylinder 4 is provided with a cutting edge, and the propeller blade is driven by a variable frequency speed regulation power device to cut and crush the material through the narrow space formed between the outer edge of the propeller blade and each filter hole of the cylinder. Moreover, under the action of the propeller blade, the material continuously rolls, collides, and rubs against each other, which also has the effect of crushing the material. In this process, the material that meets the size requirements after cutting and crushing will continuously fall into the drying bin through the filter holes of the cylinder. After sufficient cutting, crushing and decomposition, the materials that meet the requirements enter the drying bin through the discharge hopper set at the bottom of the shell. Open the gate valve, and the remaining large pieces of material that cannot be cut, crushed and decomposed will be discharged into the recycling barrel from the large piece material outlet set at the end of the cylinder under the push of the propeller blade. This processing method saves a lot of manpower and material resources, has a good crushing effect, realizes the automatic cutting, crushing and screening of materials, has high working reliability, and meets the current environmental protection requirements;

[0031] The backwash connector 6 is connected to an external water supply pump.
