Description

Technical Field

[0001] The utility model relates to the field of garbage disposal, in particular to a high-pressure extrusion device for organic garbage. Background Art

[0002] Organic waste, also known as wet waste, refers to waste containing organic components in domestic waste, mainly paper, fiber, bamboo, kitchen waste, etc. In order to improve processing efficiency, facilitate resource recycling, and reduce environmental pollution, it is often necessary to pre-treat organic waste by solid-liquid separation.

[0003] Based on the characteristics of organic waste, high-pressure extrusion equipment is generally used to separate the solid and liquid of organic waste. That is, the organic waste is put into the extrusion chamber of the high-pressure extrusion equipment, and the extrusion head located at one lateral end of the extrusion chamber applies extrusion force to the extrusion chamber in the lateral direction. During the extrusion process, the easily flowing water, organic matter and other wet materials in the organic waste are discharged from the filter holes around the extrusion chamber, while most of the dry materials such as plastics, larger fibers, sand and gravel, and metals remain in the extrusion cavity due to their lack of fluidity. After the extrusion is completed, the gate at the other lateral end of the extrusion chamber is opened, and the dry materials are sent out of the extrusion chamber under the continued action of the extrusion head, thereby achieving the purpose of solid-liquid separation.

[0004] However, in the actual operation process, the above equipment still has certain disadvantages: ① Due to the filter holes arranged around the extrusion chamber, its strength is reduced. Due to the high pressure of the working environment, the extrusion chamber is prone to deformation under the repeated action of high pressure, which in turn affects the solid-liquid separation effect; ② Due to the complex composition of organic waste, the part of the extrusion chamber where the extrusion head extends is prone to wear under the action of organic waste, which will affect the stability of equipment operation over time. Summary of the invention

[0005] In view of the deficiencies in the prior art, the utility model aims to provide an organic waste high-pressure extrusion device that can operate stably for a long time.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: including an extrusion box, a feeding module, an extrusion module, a gate module, a wet material discharging module and a dry material discharging module, wherein a transversely through extrusion chamber is arranged in the extrusion box, the feeding module is located above the extrusion box and feeds organic waste into the extrusion chamber, the wet material discharging module is located below the extrusion box and receives the wet material extruded from the organic waste, the extrusion module and the dry material discharging module are respectively located at the lateral ends of the extrusion box, the dry material discharging module is used to receive the dry material generated after the organic waste is extruded, the gate module controls the connection or disconnection between the extrusion chamber and the dry material discharging module, and the extrusion module generates an extrusion that acts laterally on the organic waste. force, characterized in that: the longitudinal cross-section of the extrusion chamber is rectangular, the extrusion chamber includes a stationary part and an extrusion part in sequence along the direction of the extrusion module toward the gate module, the connection point between the feeding module and the extrusion chamber is located above the stationary part, the extrusion box is located at the bottom of the stationary part and is provided with a plurality of first filter holes, the extrusion box is located at the outer side of the connection between the stationary part and the extrusion part and is fixedly provided with a first reinforcing rib, the extrusion part is provided with a plurality of extrusion sections at intervals along the lateral direction, the extrusion box is located at each extrusion section and is respectively provided with a plurality of groups of second filter holes arranged along the lateral direction, each group of the second filter holes is distributed on the side and bottom of the extrusion section, and the extrusion box is located at the outer side between adjacent extrusion sections and is provided with a second reinforcing rib.

[0007] By adopting the above technical scheme, the feeding module accurately feeds the organic waste into the static part of the extrusion chamber. Since the wet material carried by the organic waste will only drip downward at this time, only the first filter hole is set at the bottom to reduce the number of filter holes, thereby ensuring the strength of the extrusion box at the static part. When the extrusion module is started, the organic waste is pushed into the extrusion part by the extrusion module and extruded and deformed, and the wet material will be squeezed out from the side and bottom. Therefore, the second filter holes are arranged on the extrusion part except the top surface. In order to ensure the strength of the extrusion part, the second filter holes are only arranged in the extrusion section. The extrusion box is located on the outside between adjacent extrusion sections. A second reinforcing rib is set, which greatly reduces the possibility of deformation, thereby ensuring the long-term stable operation of the equipment.

[0008] The utility model is further configured such that the width of each of the extrusion sections gradually decreases as it moves away from the extrusion module.

[0009] By adopting the above technical solution, during the extrusion process, the pressure on the extrusion part gradually increases as it moves away from the extrusion module. Therefore, the anti-deformation strength of the extrusion part is increased by shortening the width of the extrusion part, thereby improving the stability of equipment operation.

[0011] By adopting the above technical solution, a double-layer reinforcement structure of an outer frame and an inner frame is added between the front extrusion seat and the rear extrusion seat, which effectively provides the overall strength of the extrusion head. At the same time, the inner frame plate is provided with a third reinforcement rib passing through the outer frame plate to form a cross reinforcement structure to further enhance the overall strength of the extrusion head. Secondly, the alignment slot is plugged into the inner frame plate, and the assembly slot is plugged into the outer frame plate, so that rapid positioning can be achieved while stably maintaining the shape during the welding process, which is easier to weld.

[0012] The utility model is further configured as follows: the end surface of the front end extrusion seat facing the extrusion chamber is covered with an end wear-resistant plate fixed by bolts, the cross-section of the end wear-resistant plate is larger than the front end extrusion seat, forming a wear-resistant cavity surrounding the front end extrusion seat, and the wear-resistant cavity is provided with a side wear-resistant plate fixed to the front end extrusion seat and the outer frame plate by bolts.

[0013] By adopting the above technical scheme, the front end extrusion seat is covered with the easily removable end wear-resistant plate and the side wear-resistant plate. On the one hand, the wear-resistant plate replaces the extrusion head to rub against the organic waste, thereby improving the wear resistance of the extrusion head. On the other hand, when the wear reaches a certain degree, the wear resistance can be restored by partially replacing the wear-resistant plate, thereby ensuring long-term and stable operation.

[0014] The utility model is further configured as follows: the end wear-resistant plate includes three wear-resistant split plates arranged at the upper, middle and lower portions, the upper edge of the wear-resistant split plate located at the upper portion and the lower edge of the wear-resistant split plate located at the lower portion are respectively provided with cutting blades along the longitudinal direction, the outer side of the cutting blades is in contact with the inner wall of the extrusion chamber, and the inner side gradually approaches the end wear-resistant plate as it moves away from the inner wall of the extrusion chamber.

At the same time, cutting blades are added to the edges of the wear-resistant sub-plates. On the one hand, the organic waste attached to the inner wall of the extrusion chamber is quickly separated from the inner wall of the extrusion chamber during the extrusion process to avoid hindering the movement of the extrusion head and causing wear of the extrusion head. On the other hand, the separated organic waste is guided and concentrated to the middle part, which is easier for subsequent extrusion.

On the other hand, when the wear reaches a certain extent, the wear resistance can be restored by partially replacing the wear-resistant plate, thereby ensuring long-term and stable operation. In addition, the end wear-resistant plate 316 and the side wear-resistant plate 317 can be made of various commercially available wear-resistant materials, and the commercially available Hardox wear-resistant plate is preferred.
