Description

Technical Field

[0001] This utility model relates to the field of waste treatment technology, specifically to a waste crushing and extrusion machine. Background Technology

[0002] With the acceleration of urbanization and the expansion of industrial production, the output of solid waste such as municipal solid waste and industrial slag continues to grow, making waste reduction and harmless treatment an important issue in the environmental protection field. Compression processing, as one of the core technologies for waste volume reduction, compresses waste by applying pressure, which can effectively reduce transportation costs and improve the efficiency of subsequent landfill or incineration. It is currently widely used in waste transfer stations, landfills, and resource recycling plants.

[0003] Existing waste compression equipment has the following shortcomings in practical applications: First, the precision of compression degree control is low, relying mainly on screw speed or fixed orifice control, making it difficult to flexibly adjust the compression pressure and time according to the type of waste, which can easily lead to insufficient or excessive compression of some waste, causing equipment overload. Second, the solid-liquid separation effect is poor. Liquids such as sewage and grease contained in the waste are easily left in the solid waste during the compression process, which not only increases the risk of corrosion of subsequent processing equipment, but may also cause secondary pollution. Third, equipment maintenance is inconvenient. The internal compression chamber, screw and other components are prone to blockage or wear due to long-term contact with waste, but the existing structure often lacks convenient maintenance channels. Cleaning and component replacement require disassembling a large number of external structures, resulting in low maintenance efficiency and high cost. Utility Model Content

[0004] In view of the problems in the related technologies, this utility model proposes a waste crushing and extrusion machine to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] Therefore, the specific technical solution adopted by this utility model is as follows:

[0006] A waste crushing and compressing machine includes a shell structure, a drive motor on one side of the shell structure, a support frame at the bottom of the shell structure, a cavity structure installed inside the shell structure, a screw installed inside the cavity structure, a transmission structure on one side of the cavity structure, and a valve structure connected to the transmission structure. The cavity structure, together with the drive motor and the screw, realizes the function of crushing waste, while the transmission structure and the valve structure realize the function of controlling the degree of crushing of waste.

[0007] Furthermore, the shell structure includes a protective shell and a discharge port. The discharge port is provided at the bottom of the protective shell. The protective shell is fixedly installed on the support frame. The drive shaft of the drive motor is rotatably connected to one side of the protective shell. The drive motor is fixedly installed on the support frame, and the drive shaft of the drive motor is fixedly connected to a screw.

[0008] Furthermore, the cavity structure includes a feed hopper, an extrusion cone, a maintenance plate, and a support block. The bottom end of the extrusion cone has an inspection port, and the maintenance plate fits onto the inspection port. The feed hopper is connected to the extrusion cone, and the support block is fixedly connected to the extrusion cone. The extrusion cone is fixedly installed inside the protective shell through the support block.

[0009] Furthermore, the transmission structure includes a hydraulic cylinder, a drive rod, a connecting lug, a transmission block, and a water filter cover. The drive end of the hydraulic cylinder is connected to the drive rod, the drive rod is fixedly connected to the connecting lug, the connecting lug is fixedly connected to the transmission block, and a water filter cover is fixedly connected to one side of the transmission block. The hydraulic cylinder is fixedly installed inside the protective housing.

[0010] Furthermore, the valve structure includes a baffle, a connecting hole, a filter ring, a filter hole, and a guide seat. The baffle has a connecting hole and is fixedly connected to the drive rod through the connecting hole. A filter ring is installed on the baffle, and a filter hole is opened on the filter ring. Guide seats are installed at both ends of the baffle, and guide rollers are installed on the guide seats. The guide seats slide in contact with the inner wall of the protective shell through the guide rollers. One side of the baffle is connected to one end of the extrusion cone, and the other side of the baffle is connected to the filter cover.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. By using a tapered progressive screw in conjunction with a compression cone, the cone's conical space design gradually reduces the compression area, enhancing the forward compression effect on waste and significantly improving the waste volume reduction rate. It is suitable for the compression treatment of various types of waste.

[0013] 2. The hydraulic cylinder of the transmission structure drives the baffle of the valve structure to move, realizing the opening and closing control of the outlet at the end of the extrusion cone. The extrusion time and pressure can be flexibly adjusted according to the type of waste and processing requirements to avoid excessive or insufficient extrusion and reduce the operating load of the equipment.

[0014] 3. The filter ring and filter holes of the valve structure cooperate with the filter cover of the transmission structure to simultaneously separate the liquid in the waste during the squeezing process. The liquid is guided by the filter cover to the feed port and discharged in a concentrated manner, which effectively avoids the impact of liquid residue on subsequent treatment and reduces the risk of secondary pollution.

[0025] 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.

[0026] According to an embodiment of the present invention, a waste crushing and extrusion machine is provided.

[0027] like Figure 1-7As shown, the waste crushing and extruding machine according to an embodiment of the present invention includes a shell structure 1, a drive motor 3 on one side of the shell structure 1, a support frame 2 at the bottom of the shell structure 1, a cavity structure 4 installed inside the shell structure 1, a screw 7 installed inside the cavity structure 4, a transmission structure 5 on one side of the cavity structure 4, and a valve structure 6 connected to the transmission structure 5. The cavity structure 4, together with the drive motor 3 and the screw 7, realizes the function of crushing waste, while the transmission structure 5 and the valve structure 6 realize the function of controlling the degree of crushing of waste.

[0028] The drive motor 3, as the power source of the equipment, is fixedly installed on the support frame 2. Its drive shaft is directly fixedly connected to the screw 7, providing the torque required for the screw 7 to rotate. The drive screw 7 realizes the forward pushing and squeezing action of the waste in the squeezing cone 402, and is the core power output component of the squeezing function. The support frame 2 serves as the basic support structure of the entire equipment. By fixing and installing the shell structure 1, drive motor 3 and other components, it ensures the overall stability of the equipment during operation, avoids structural displacement due to vibration or load, and ensures the accuracy of the coordinated work of each component.

[0029] like Figure 1-2 As shown, the shell structure 1 includes a protective shell 101 and a discharge port 102. The discharge port 102 is provided at the bottom end of the protective shell 101. The protective shell 101 is fixedly installed on the support frame 2. The drive shaft of the drive motor 3 is rotatably connected to one side end of the protective shell 101. The drive motor 3 is fixedly installed on the support frame 2. The drive shaft of the drive motor 3 is fixedly connected to the screw 7.

[0030] The core function of the shell structure 1 is to provide protection, support and basic installation frame for the entire equipment. The protective shell 101 contained therein serves as the external main body and is fixedly installed on the support frame 2 to form a stable structure. It not only provides physical protection for the core components such as the internal cavity structure 4 and transmission structure 5, but also provides an installation benchmark for the drive motor 3. The discharge port 102 opened at the bottom of the protective shell 101 is the final discharge port of the equipment, which is used to uniformly discharge the liquid and solid waste separated after compression, so as to realize the centralized collection of processed materials.

[0031] like Figure 3 and Figure 5 as well as Figure 6 As shown, the cavity structure 4 includes a feed hopper 401, an extrusion cone 402, a maintenance plate 403, and a support block 404. The bottom end of the extrusion cone 402 has an inspection port, and the maintenance plate 403 fits onto the inspection port. The feed hopper 401 is connected to the extrusion cone 402, and the support block 404 is fixedly connected to the extrusion cone 402. The extrusion cone 402 is fixedly installed inside the protective shell 101 through the support block 404.

[0032] The cavity structure 4 is the core working area for waste compression processing. It is fixedly installed inside the protective shell 101 by the support block 404, forming an independent and stable compression space. The feed hopper 401 serves as a waste inlet channel, directly connected to the compression cone 402, ensuring that the waste to be processed can accurately enter the compression area. The compression cone 402 serves as the main cavity, working in conjunction with the screw 7 to achieve the compression function. The screw 7 rotates under the drive motor 3, using a tapered progressive structure to push and compress the waste entering the cone. The tapered design of the cone can gradually reduce the space, enhancing the compression effect. In addition, the inspection port and fitting inspection plate 403 at the bottom of the compression cone 402 facilitate the cleaning of the internal screw 7 or blockages during routine maintenance, ensuring the continuous and stable operation of the equipment.

[0033] like Figure 3 , Figure 4 as well as Figure 7 As shown, the transmission structure 5 includes a hydraulic cylinder 501, a drive rod 502, a connecting ear 503, a transmission block 504, and a water filter cover 505. The drive end of the hydraulic cylinder 501 is connected to the drive rod 502. The drive rod 502 is fixedly connected to the connecting ear 503. The connecting ear 503 is fixedly connected to the transmission block 504. The water filter cover 505 is fixedly connected to one side of the transmission block 504. The hydraulic cylinder 501 is fixedly installed inside the protective shell 101.

[0034] The transmission structure 5 is a power execution unit that controls the degree of garbage compression. It provides driving force through the hydraulic cylinder 501, which is transmitted to the transmission block 504 through the drive rod 502 and the connecting lug 503, thereby driving the valve structure 6 to move. The hydraulic cylinder 501 is fixedly installed inside the protective shell 101. The extension and retraction of its driving end is converted into the linear displacement of the transmission block 504 through the drive rod 502, which directly controls the opening and closing state of the baffle 601 in the valve structure 6, thereby achieving precise control of the degree of compression. At the same time, the water filter hood 505 fixed on one side of the transmission block 504 corresponds to the water filter ring 603 of the valve structure 6. It is used to collect the liquid that seeps out through the water filter hole 604 during the garbage compression process and guide it to the discharge port 102 of the shell structure 1 for discharge, so as to achieve centralized treatment of the liquid after solid-liquid separation.

[0035] like Figure 4As shown, the valve structure 6 includes a baffle 601, a connecting hole 602, a filter ring 603, a filter hole 604, and a guide seat 605. The baffle 601 has a connecting hole 602 and is fixedly connected to the drive rod 502 through the connecting hole 602. The filter ring 603 is installed on the baffle 601 and has a filter hole 604. The guide seats 605 are installed at both ends of the baffle 601 and have guide rollers installed on them. The guide seats 605 slide in contact with the inner wall of the protective shell 101 through the guide rollers. One side of the baffle 601 is connected to one end of the extrusion cone 402, and the other side of the baffle 601 is connected to the filter cover 505.

[0036] Valve structure 6 is a key component for controlling the degree of compression and solid-liquid separation. Its core is baffle 601, which is fixedly connected to drive rod 502 of transmission structure 5 through connection hole 602. Under the drive of transmission structure 5, it slides along the inner wall of protective shell 101 to realize the opening and closing of the outlet at the end of compression cone 402. The filter ring 603 and the filter hole 604 installed on baffle 601 are the core of solid-liquid separation. When baffle 601 is closed, the waste is pushed by screw 7 and comes into close contact with baffle 601. The liquid generated by compression permeates through the filter hole 604 to the inside of filter ring 603 and then enters the filter cover 505 of transmission structure 5. When the waste reaches the set degree of compression, baffle 601 is opened under the drive of transmission structure 5. Screw 7 pushes the compressed solid waste directly from the end of cone to discharge port 102, completing the entire compression-separation-discharge process.

[0037] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0038] In actual use, the waste to be processed is fed into the extrusion cone 402 through the feed hopper 401. The drive motor 3 drives the screw 7, which is a tapered progressive screw that can push and squeeze the waste fed into the extrusion cone 402. When the waste is pushed and squeezed to the end of the cone, that is, the end that contacts the baffle 601, the continuous drive of the screw 7 will keep the waste being squeezed. At the same time, the liquid in the waste will enter the water filter hood 505 through the water filter hole 604 of the water filter ring 603, and finally be discharged through the water filter hood 505 to the discharge port 102. After the waste reaches the degree of compression, the hydraulic cylinder 501 of the transmission structure 5 and the drive rod 502 drive the transmission block 504 and the baffle 601 to move, so that the screw 7 can drive the squeezed waste to be discharged from the end of the cone to the discharge port 102.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
