Description

Technical Field

[0001] This utility model relates to the field of waste treatment technology, specifically to a comprehensive waste utilization pretreatment device. Background Technology

[0002] With the rapid development of modern industry and the continuous improvement of people's living standards, the amount of comprehensive waste generated in various production activities and daily consumption processes has increased dramatically. This comprehensive waste is complex and diverse, encompassing solids, liquids, and mixtures of different forms of matter. If not properly treated, it will cause serious environmental pollution and result in a huge waste of resources.

[0003] Traditional waste disposal methods often have many limitations. When faced with mixed waste, many processing devices lack effective pretreatment methods to initially separate the liquid components. As a result, the liquid may interfere with further processing of solid waste, such as affecting the effectiveness of crushing and screening, and the overall processing efficiency is low. Utility Model Content

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this utility model is as follows: a comprehensive waste utilization pretreatment device, comprising: a support base, a housing fixedly connected to the top of the support base, a feed hopper fixedly connected to the top of the housing, a filter cylinder fixedly connected to the bottom of the feed hopper, a spiral conveying paddle rotatably connected to the inner side of the filter cylinder, a drive motor fixedly connected to the outer side of the housing, and a liquid outlet pipe fixedly connected to the bottom of the housing. Liquid in the waste can flow downwards along the surface of the filter cylinder into the housing, and finally be discharged outwards through the liquid outlet pipe, thereby achieving effective discharge of liquid components in the waste and completing the initial solid-liquid separation function.

[0005] The extrusion assembly has its bottom fixedly connected to the top of the support base, and its outer side fixedly connected to the outer side of the housing. The extrusion assembly includes a protective shell, a rotating shaft rotatably connected to the center of the protective shell, a rotating frame fixedly connected to the outer wall of the rotating shaft, a fixed cylinder fixedly connected to the outer side of the rotating frame, a sliding block slidably connected to the inner wall of the fixed cylinder, an extrusion roller rotatably connected to the outer side of the sliding block, a compression spring fixedly connected to the inner side of the fixed cylinder, a leakage shell fixedly connected to the bottom of the protective shell, and a discharge pipe fixedly connected to the outer side of the protective shell. When the screw conveyor paddle rotates continuously under the drive of the drive motor, it drives the rotating shaft to rotate synchronously. At this time, the rotating frame fixed to the outer wall of the rotating shaft also rotates around the rotating shaft inside the protective shell. When the rotating frame rotates, the extrusion roller extrudes against the inner wall of the protective shell.

[0006] Preferably, the outer side of the filter cartridge is fixedly connected to the inner side of the housing, the output end of the drive motor is fixedly connected to the outer side of the spiral conveyor, the bottom of the protective shell is fixedly connected to the top of the support base, and the outer side of the protective shell is fixedly connected to the outer side of the housing. The drive motor starts and drives the spiral conveyor to rotate. The spiral conveyor rotates inside the filter cartridge, and through the rotation of the spiral blades, it conveys the waste that has undergone preliminary filtration into the filter cartridge along the axial direction of the filter cartridge.

[0007] Preferably, the side of the spiral conveyor blade away from the drive motor is fixedly connected to the outside of the rotating shaft, and the outside of the leakage shell is fixedly connected to the outside of the outlet pipe. During the extrusion process, the squeezed liquid is collected through the leakage shell fixedly connected to the bottom of the protective shell, and the collected liquid flows into the outlet pipe along the leakage shell.

[0008] Preferably, the outer side of the rotating frame is rotatably connected to the inner side of the protective shell, the outer side of the compression spring is fixedly connected to the inner side of the sliding block, and the outer wall of the extrusion roller is rollingly connected to the inner wall of the protective shell. During the process of the extrusion roller extruding into the inner wall of the protective shell, the waste is sandwiched between the extrusion roller and the inner wall of the protective shell, thereby achieving the extrusion treatment of the waste.

[0009] Preferably, a scraper is fixedly connected to the inner side of the discharge pipe, and an elastic lever is fixedly connected to the outer side of the rotating frame. The outer side of the elastic lever is slidably connected to the inner wall of the protective shell. The scraper, which is arranged in a staggered manner with the elastic lever, will scrape off the waste attached to the elastic lever, ensuring that all the processed waste can enter the discharge pipe as much as possible.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. This utility model incorporates a filter cylinder and a drive motor that rotates a spiral conveyor. The spiral conveyor rotates inside the filter cylinder, transporting the pre-filtered waste along the axial direction of the filter cylinder towards the extrusion assembly, preparing it for subsequent extrusion processing. During this process, the liquid in the waste flows downwards along the surface of the filter cylinder into the housing, and is finally discharged outwards through the liquid outlet pipe, effectively removing the liquid components from the waste and completing the initial solid-liquid separation function.

[0012] 2. This utility model, by setting up a compression assembly, achieves waste treatment by trapping the waste between the compression roller and the inner wall of the protective shell during the compression process. This squeezes out the liquid from the waste, achieving solid-liquid separation. During the compression process, the squeezed liquid is collected through a leaking shell fixedly connected to the bottom of the protective shell. The collected liquid flows along the leaking shell into the outlet pipe and is finally discharged from the equipment through the outlet pipe, completing the liquid separation and collection.

[0013] 3. This utility model, by setting up an elastic lever and a scraper, ensures that when the elastic lever moves to the position of the discharge pipe, it returns to its original shape and pushes the waste into the discharge pipe. During the movement of the elastic lever, the scraper, which is arranged in a staggered manner with the elastic lever, scrapes off the waste attached to the elastic lever, ensuring that all processed waste can enter the discharge pipe as much as possible, thereby improving the integrity and efficiency of waste discharge.

Detailed Implementation

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0020] Example: Please refer to Figure 1 - Figure 4This utility model provides a technical solution: a pretreatment device for comprehensive waste utilization, comprising: a support base 1, a housing 2 fixedly connected to the top of the support base 1, a feed hopper 3 fixedly connected to the top of the housing 2, a filter cylinder 5 fixedly connected to the bottom of the feed hopper 3, a spiral conveyor 7 rotatably connected to the inner side of the filter cylinder 5, a drive motor 6 fixedly connected to the outer side of the housing 2, and a liquid outlet pipe 8 fixedly connected to the bottom of the housing 2. The device is placed in a designated position by the support base 1, and the comprehensive waste is poured into the filter cylinder 5 inside the housing 2 through the feed hopper 3. At the same time, the drive motor 6 installed on the outer side of the housing 2 is started and drives the spiral conveyor 7 to rotate. The spiral conveyor 7 rotates inside the filter cylinder 5. Through the rotation of the spiral blades, the waste that has undergone preliminary filtration in the filter cylinder 5 is conveyed along the axial direction of the filter cylinder 5, moving it towards the direction of the extrusion assembly 4 to prepare for subsequent extrusion processing. During this process, the liquid in the waste flows downward along the surface of the filter cylinder 5 into the housing 2, and is finally discharged outward through the liquid outlet pipe 8, realizing the effective discharge of the liquid components in the waste and completing the preliminary solid-liquid separation function.

[0021] The extrusion assembly 4 is fixedly connected to the top of the support base 1 at its bottom and to the outside of the housing 2 at its outer side. The extrusion assembly 4 includes a protective shell 41, a rotating shaft 42 rotatably connected to the center of the protective shell 41, a rotating frame 43 fixedly connected to the outer wall of the rotating shaft 42, a fixed cylinder 44 fixedly connected to the outer side of the rotating frame 43, a sliding block 45 slidably connected to the inner wall of the fixed cylinder 44, an extrusion roller 46 rotatably connected to the outer side of the sliding block 45, a compression spring 47 fixedly connected to the inner side of the fixed cylinder 44, a leakage shell 410 fixedly connected to the bottom of the protective shell 41, a discharge pipe 49 fixedly connected to the outer side of the protective shell 41, a filter cylinder 5 fixedly connected to the inner side of the housing 2 at its outer side, an output end of a drive motor 6 fixedly connected to the outer side of a screw conveyor 7, a bottom of the protective shell 41 fixedly connected to the top of the support base 1, and an outer side of the protective shell 41 fixedly connected to the outer side of the housing 2. When the screw conveyor 7 rotates continuously under the drive of the drive motor 6, it will drive the rotating shaft 42 to rotate synchronously. At this time, the rotating frame 43, which is fixed to the outer wall of the rotating shaft 42, will also rotate around the rotating shaft 42 inside the protective shell 41. When the rotating frame 43 rotates, the extrusion roller 46 extrudes against the inner wall of the protective shell 41. At the same time, under the elastic force of the compression spring 47, the sliding block 45 always maintains the tendency to slide outward of the fixed cylinder 44, thereby ensuring that the extrusion roller 46 extrudes the waste in a moderate and effective manner.

[0022] The side of the screw conveyor 7 furthest from the drive motor 6 is fixedly connected to the outer side of the rotating shaft 42. The outer side of the leakage shell 410 is fixedly connected to the outer side of the liquid outlet pipe 8. The outer side of the rotating frame 43 is rotatably connected to the inner side of the protective shell 41. The outer side of the compression spring 47 is fixedly connected to the inner side of the sliding block 45. The outer wall of the extrusion roller 46 is rollingly connected to the inner wall of the protective shell 41. A scraper 40 is fixedly connected to the inner side of the discharge pipe 49. An elastic lever 48 is fixedly connected to the outer side of the rotating frame 43. The outer side of the elastic lever 48 is slidably connected to the inner wall of the protective shell 41. During the process of the extrusion roller 46 squeezing the inner wall of the protective shell 41, the waste is trapped between the extrusion roller 46 and the inner wall of the protective shell 41, thus achieving the extrusion treatment of the waste. The liquid in the waste is squeezed out, achieving solid-liquid separation. During the extrusion process, the squeezed liquid is collected through the leakage shell 410 fixedly connected to the bottom of the protective shell 41. The collected liquid flows into the outlet pipe 8 along the leakage shell 410 and is finally discharged from the equipment through the outlet pipe 8, completing the separation and collection of liquid. Meanwhile, the elastic lever 48 maintains elastic deformation when sliding inside the protective shell 41, and drives the waste to move towards the discharge pipe 49. When the elastic lever 48 moves to the position of the discharge pipe 49, the elastic lever 48 returns to its original deformation, pushing the waste into the discharge pipe 49. During the movement of the elastic lever 48, the scraper bars 40 arranged alternately with the elastic lever 48 will scrape off the waste attached to the elastic lever 48, ensuring that all the processed waste can enter the discharge pipe 49 as much as possible, improving the integrity and efficiency of waste discharge.

[0023] Working principle:

[0024] In use, the device is placed in the designated position using the support base 1. The waste is poured into the filter cylinder 5 inside the housing 2 through the feed hopper 3. Simultaneously, the drive motor 6, installed on the outside of the housing 2, starts and drives the screw conveyor 7 to rotate. The screw conveyor 7 rotates inside the filter cylinder 5, and through the rotation of the helical blades, the waste that has undergone preliminary filtration is conveyed along the axial direction of the filter cylinder 5, moving it towards the extrusion assembly 4 to prepare for subsequent extrusion processing. During this process, the liquid in the waste flows downwards along the surface of the filter cylinder 5 into the housing 2, and finally is discharged outwards through the liquid outlet pipe 8, achieving effective discharge of the liquid components from the waste and completing the initial solid-liquid separation function.

[0025] Meanwhile, as the screw conveyor 7 rotates continuously under the drive of the drive motor 6, it drives the rotating shaft 42 to rotate synchronously. At this time, the rotating frame 43, which is fixed to the outer wall of the rotating shaft 42, also rotates around the rotating shaft 42 inside the protective shell 41. When the rotating frame 43 rotates, the extrusion roller 46 presses against the inner wall of the protective shell 41. At the same time, under the elastic force of the compression spring 47, the sliding block 45 always maintains the tendency to slide outward of the fixed cylinder 44, thereby ensuring that the extrusion roller 46 extrudes waste material in a moderate and effective manner.

[0026] During the process of the extrusion roller 46 pressing against the inner wall of the protective shell 41, the waste is trapped between the extrusion roller 46 and the inner wall of the protective shell 41, achieving extrusion processing of the waste. The liquid in the waste is squeezed out, achieving solid-liquid separation. During the extrusion process, the squeezed liquid is collected through the leakage shell 410 fixedly connected to the bottom of the protective shell 41. The collected liquid flows along the leakage shell 410 into the outlet pipe 8, and finally is discharged from the equipment through the outlet pipe 8, completing the separation and collection of the liquid.

[0027] The elastic lever 48 maintains its elastic deformation while sliding inside the protective shell 41, and moves the waste towards the discharge pipe 49. When the elastic lever 48 moves to the position of the discharge pipe 49, the elastic lever 48 returns to its original deformation and pushes the waste into the discharge pipe 49. During the movement of the elastic lever 48, the scraper bars 40, which are arranged in a staggered manner with the elastic lever 48, will scrape off the waste attached to the elastic lever 48, ensuring that all the processed waste can enter the discharge pipe 49 as much as possible, thereby improving the integrity and efficiency of waste discharge.

All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model.
