With the continuous acceleration of the urbanization process, the amount of municipal solid waste is increasing rapidly, and the growth rate is also increasing rapidly. The harmlessness, reduction and recycling of garbage disposal is an important content of urban management. Garbage shredding is an important link in the process of realizing the "three modernizations" of garbage, and the pretreatment technology of garbage shredding plays an important role in subsequent sorting, crushing, and incineration. The garbage shredding pre-compressor is the key to realize the garbage shredding pre-compression technology The performance of the main equipment directly affects the subsequent processing effect.

The existing municipal solid waste crushing pre-compressor is often unable to continuously feed the crusher, or the feeding speed is too slow to meet the high-frequency crushing requirements of the crusher. At the same time, the compression direction of the existing municipal solid waste crushing pre-compressor pre-compression mechanism is often on the same straight line as the cutter shaft of the crushing knife. Larger pressure will deform the cutter shaft, which is not conducive to crushing, but also affects safe production. brought hidden dangers.

Detailed ways

The embodiments of the present invention are described in detail below. This embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operating procedures are provided, but the protection scope of the present invention is not limited to the following implementation example.

A pre-compressor for municipal solid waste crushing, comprising a feed port 3, a compression chamber 2, a discharge port 4 and a motor 1, the compression chamber 2 is arranged between the feed port 3 and the discharge port 4, and its characteristics In that: a compression rotor 5 is arranged in the compression chamber 2, the compression rotor 5 is a Leroux triangular rotor, the compression chamber 2 is cocoon-shaped, a rotor hole 51 is arranged in the center of the compression rotor 5, and a rotor gear 52 is arranged on the inner wall of the rotor hole 51, and in the rotor hole Rotor shaft 53 is also provided, and rotor shaft 53 is an eccentric shaft, and rotor shaft 53 is positioned at one end of rotor and rotor shaft gear 54 is arranged, and rotor shaft gear 54 meshes with rotor gear 52, and the other end of rotor shaft 53 is connected with motor 1, and motor 1 runs At the same time, it can drive the compression rotor 5 to rotate around its center, and also drive the compression rotor 5 to revolve around the center of the compression chamber 2. During the rotation, the three corners of the compression rotor 5 are always close to the inner wall of the compression chamber 2. The compression rotor 5 in the shape of a Leroux triangle divides the cocoon-shaped compression chamber 2 into three areas, namely, a material storage area 21 , a compression area 22 and a discharge area 23 . The storage area 21 is located below the feed port 3, and the storage area 21 is converted into a compression area 22 by the rotation of the compression rotor 5. Through the cooperation of the compression rotor 5 and the compression chamber 2, the space of the compression area 22 gradually becomes smaller, thereby realizing the compression operation , and then rotate with the compression rotor 5, the compression zone 22 is converted into a discharge zone 23, and the discharge zone 23 is located above the discharge port 4, and after the discharge operation is completed, the discharge zone 23 is converted into a storage zone 21 again. Such cycle operation realizes the continuous operation of storage, compression and discharge, which solves the shortcoming of only intermittent operation of traditional compressors. The three areas complete their respective cycles independently without affecting each other, and the compression rotor 5 can complete three compression operations in one cycle, and the compression efficiency is very high. The compression direction of the compression operation faces the side wall of the compression chamber 2, unlike the traditional compressor where the compression direction points to the crushing knife edge, which greatly reduces the pressure on the crushing knife shaft. The compression chamber 2 and the compression rotor 5 are made of materials with high wear resistance, high strength and low linear expansion rate.

A screw push rod 6 is arranged above the feeding port 3 . The design of the screw push rod 6 increases the feed speed of the feed port 3, greatly increases the storage speed of the material storage area 21, and improves the compression efficiency of the pre-compressor.

The ratio of the rotor shaft gear 54 to the rotor gear 52 is 1:2.

The compression cavity 2 is constructed by the incision method. The inscribed creation method can ensure that the shape of the compression chamber 2 coincides with the cycloid shape of the three corners of the compression rotor 5, thereby ensuring that the three corners of the compression rotor 5 are always in close contact with the inner wall of the compression chamber 2 during operation, ensuring The storage area 21, the compression area 22 and the discharge area 23 are completely separated to ensure the effectiveness of the compression operation.

The centerline of the feed port 3 and the center line of the discharge port 4 are on the same straight line, the center line of the feed port 3 and the center line of the discharge port 4 are not on the same straight line as the center line of the compression chamber 2, and the feed The distance between the centerline of the opening 3 and the centerline of the discharge port 4 and the centerline of the compression chamber 2 is 1/4 of the width of the compression chamber 2 . The opening diameter of the feed port 3 and the opening diameter of the discharge port 4 are not greater than half of the width of the compression chamber 2 . Such a design can ensure the storage time of the storage area 21 and the discharge time of the discharge area 23, so that the operation of each step can be as complete as possible, thereby ensuring the working efficiency of the pre-compressor. If the opening diameter of the feed port 3 is too large or too small, its storage speed will be affected. The feed port 3 and the discharge port 4 are arranged on the same side of the axis of the compression chamber 2, so that the storage and discharge time can be compressed as much as possible, the compression operation time can be prolonged, and the compression effect of the pre-compressor can be guaranteed.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the protection of the present invention. within range.
