Technical Field

[0001] This utility model relates to the field of waste treatment technology, and in particular to a waste-to-energy pretreatment device. Background Technology

[0002] Waste-to-energy (WGE) plays an important role in environmental protection and energy as an effective method of waste treatment and energy recovery. As a key link in the waste-to-energy process, the performance of the pre-treatment unit directly affects the subsequent power generation efficiency and waste treatment effect. The main function of the pre-treatment unit is to classify, crush, and screen the collected waste, transforming it into raw materials suitable for power generation, ensuring the stable operation of the power generation equipment, and improving the quality of power generation.

[0003] Existing waste-to-energy pretreatment devices typically crush waste into fine particles before incineration to generate electricity, thereby accelerating incineration efficiency. However, traditional waste crushing devices do not crush waste thoroughly enough, leaving many large pieces after crushing, which affects incineration efficiency. Therefore, it is necessary to design a waste-to-energy pretreatment device that can effectively filter large pieces of waste and perform secondary crushing to solve the problem of large pieces of waste still affecting incineration efficiency after crushing. Utility Model Content

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution:

[0023] Example 1:

[0024] like Figure 1-4 As shown, a waste-to-energy pretreatment device includes a housing 1 and a crushing roller 2 installed inside the housing 1. A filter plate 3 is slidably connected to the inner wall of the housing 1, and a shaking assembly is installed on the outer wall of the filter plate 3. The shaking assembly includes a squeezing block 4, a movable frame 5, and a push rod 6. The crushing roller 2 is connected to a drive motor on the outer wall of the housing 1. The squeezing block 4 is fixedly connected to the output shaft of the drive motor. A sealing ring is installed at the connection between the output shaft of the drive motor and the housing 1. The movable frame 5 is slidably connected to the outer surface of the housing 1. The rotating squeezing block 4 is movably connected to the vertical arm of the movable frame 5. The push rod 6 is fixedly connected to one side of the movable frame 5. A sealing sleeve is installed at the connection between the push rod 6 and the housing 1. The push rod 6 is fixedly connected to the outer wall of the filter plate 3. A side plate 7 is fixedly connected to the top of the filter plate 3. The side plate 7 can prevent waste from overflowing. A feeding assembly is installed inside the housing 1, and a guide rail is installed on the outer wall of the housing 1 to provide lateral limit for the movable frame 5.

[0025] Example 2:

[0026] The technical solution is basically the same as that in Embodiment 1, except that, as Figure 2 and Figure 4 As shown, the feeding assembly includes a scraper 8, a lead screw 9, a motor 10, and a rotating plate 11. The top of the filter plate 3 is slidably connected to the scraper 8, the inner wall of the housing 1 is rotatably connected to the lead screw 9, the scraper 8 is threadedly connected to the outer wall of the lead screw 9, the outer wall of the housing 1 is equipped with the motor 10, the motor 10 is installed at the end of the lead screw 9 away from the scraper 8, the side of the housing 1 away from the scraper 8 is rotatably connected to the rotating plate 11, and the filter plate 3 and the housing 1 are connected to each other by a spring 12.

[0027] Example 3:

[0028] The technical solution is basically the same as that in Embodiment 1, except that, as Figure 4 As shown, a protective plate 13 is fixedly connected to the inner wall of the box 1. The protective plate 13 is located on the top of the lead screw 9. The cross-sectional shape of the protective plate 13 is an inverted V shape. The protective plate can prevent garbage from accumulating on the lead screw 9.

[0029] Working principle: In this embodiment, the waste-to-energy pretreatment device is used by the operator who first turns on the drive motor and then pours the waste into the container 1. The drive motor drives the crushing roller 2 to rotate, crushing the waste. The crushed waste falls onto the filter plate 3. Simultaneously, the output shaft of the drive motor drives the compression block 4 to rotate, which in turn pushes the movable frame 5 to move. Since the push rod 6 is limited by the container 1 and can only move horizontally, the movable frame 5, which is fixedly connected to the push rod 6, can also only move horizontally. In this way, the movable frame 5 and the push rod 6 reciprocate horizontally, causing the push rod 6 to drive the filter plate 3 to move back and forth. The filter plate 3 will shake back and forth, thus sieving out small particles and trapping large pieces of waste on the filter plate 3. Then, the staff will turn off the drive motor, and the spring 12 will push the filter plate 3 to the bottom of the scraper 8. Then, the staff will turn on the motor 10, which will drive the lead screw 9 to rotate. The lead screw 9 will move the scraper 8 through the thread, and the scraper 8 will push the large pieces of waste on the filter plate 3 to move. After the large pieces of waste have moved, they will squeeze the rotating plate 11 to rotate, so that the large pieces of waste will be discharged from one side of the box 1. The staff can then collect these large pieces of waste for secondary crushing to solve the problem that large pieces of waste still affect the incineration efficiency after the waste is crushed.

[0030] In summary, this application can effectively discharge fine particles after crushing and retain large pieces of waste through the filter plate 3 and the shaking component. This allows for secondary crushing of large pieces of waste, solving the problem that large pieces of waste still affect incineration efficiency after crushing. After the large pieces of waste are retained by the filter plate 3, the staff can automatically push the large pieces of waste out of the box 1 through the feeding component. This eliminates the need for staff to manually collect the large pieces of waste on the filter plate 3. The inverted V-shaped protective plate 13 inside the box 1 can prevent the crushed waste from getting stuck in the thread groove of the lead screw 9, thus ensuring that the subsequent operation of the lead screw 9 and the scraper 8 is not affected.
