Description

Technical Field

[0001] This utility model relates to the technical field of kitchen waste screening equipment, specifically a kitchen waste screening mechanism. Background Technology

[0002] Kitchen waste is waste generated by residents in their daily lives during food processing and catering services. Screening kitchen waste makes it easier to classify and process different types of waste later. A star disk screener is a type of screener that uses the mechanical movement of a rotating star disk to achieve efficient and non-clogging screening. It is especially suitable for processing high-moisture or sticky materials such as household waste and kitchen waste. However, large impurities such as plastic bags and food packaging bags may become entangled in the star disk, requiring the machine to be stopped for cleaning. Therefore, this utility model proposes a kitchen waste screening mechanism. Summary of the Invention

[0003] The purpose of this invention is to provide a kitchen waste screening mechanism to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a kitchen waste screening mechanism, comprising a feeding hopper, a star-plate screener, and a vibrating screen disposed below the star-plate screener. A crushing channel is provided between the feeding hopper and the star-plate screener. A crushing shaft is rotatably mounted within the crushing channel, and multiple crushing blades are fixedly mounted on the crushing shaft. Multiple equally spaced drive shafts are rotatably mounted within the star-plate screener, and multiple star plates are equally spaced on the shafts, with the star plates on adjacent shafts arranged alternately. A receiving box is detachably installed at the bottom of the vibrating screen. The rotation of the crushing shaft within the crushing channel causes the blades on the crushing shaft to crush the passing waste, especially capable of breaking open waste wrapped in plastic bags. The drive shaft on the star-plate screener includes a drive shaft and a driven shaft. The drive shaft is driven to rotate by a motor, and the driven shaft is driven to rotate synchronously by a linkage device.

[0005] Preferably, the crushing channel is bent, and multiple crushing shafts are rotatably arranged within the crushing channel. A motor is installed on the crushing channel to drive the crushing shafts to rotate. The bent shape of the crushing channel allows the material passing through to remain in the channel for a longer time, improving the crushing effect.

[0006] Preferably, the bottom of the vibrating screen consists of two screens inclined towards the middle, and the receiving box is located at the bottom of the two screens. An air cushion is provided on the top side of the vibrating screen. A vibrating motor can be installed on the outer side of the top side of the vibrating screen. The vibrating screen vibrates by rotating the eccentric rotor inside the vibrating motor. At the same time, the air cushion acts as a buffer between the vibrating screen and the support frame to reduce the noise generated by the vibration.

[0007] Preferably, the bottom of the screen of the vibrating screen is provided with a protrusion and a screw groove is provided on the protrusion. The top of the receiving box is screwed with a bolt, and the bolt can be screwed into the screw groove on the protrusion.

[0008] Compared with the prior art, the beneficial effects of this utility model are: by rotating the crushing shaft in the crushing channel, the blades on the crushing shaft crush the passing garbage, and the bent crushing channel allows the passing material to stay in the channel for a longer time, thus improving the crushing effect.

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] Reference Figure 1 A kitchen waste screening mechanism includes a feed hopper 1, a star-plate screen 3, and a vibrating screen 4 disposed below the star-plate screen 3. A crushing channel 2 is provided between the feed hopper 1 and the star-plate screen 3. A crushing shaft 21 is rotatably mounted in the crushing channel 2, and multiple crushing blades are fixedly mounted on the crushing shaft 21. Multiple equally spaced transmission shafts 31 are rotatably mounted in the star-plate screen 3, and multiple star plates are equally spaced on the shafts, with the star plates on adjacent shafts arranged alternately. A receiving box 41 is detachably installed at the bottom of the vibrating screen 4. The crushing channel 2 is bent, and multiple crushing shafts 21 are rotatably mounted in the crushing channel 2.

[0013] The bottom of the vibrating screen 4 consists of two screens that slope inwards towards the center, and the receiving box 41 is located at the bottom of the two screens. An air cushion is provided on the top side of the vibrating screen 4. The bottom of the screens of the vibrating screen 4 is provided with protrusions, and screw grooves are provided on the protrusions. The top of the receiving box 41 is screwed with a bolt, which can be screwed into the screw groove on the protrusion.

[0014] When this device is in use, the waste is poured from the feed hopper 1 into the crushing channel 2. The crushing shaft 21 in the crushing channel 2 rotates to crush the waste. The crushed waste slides down the channel onto the star disk screen. After the material falls onto the screen surface composed of multiple drive shafts, the rotating star disk applies an impact force to the material, causing it to jump and tumble. Liquid impurities and some smaller debris fall onto the vibrating screen 4 through the gaps between the drive shafts. Liquid impurities fall through the screen surface of the vibrating screen and can be collected in a collection container and sent to the sewage treatment equipment. Some impurities that cannot pass through the vibrating screen 4 slide down into the receiving box 41 due to the vibration of the vibrating screen and the continuous flushing of the liquid falling into the vibrating screen.

[0015] The orientations or positional relationships shown in the accompanying drawings are for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0016] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0017] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
