Description

Technical Field

[0001] The present invention relates to the field related to pulverizing devices, and in particular to an environmentally friendly waste secondary recycling pulverizing device. Background Art

[0002] Construction waste refers to the general term for slag, waste concrete, waste bricks and other wastes generated by people in the production activities of the construction industry such as demolition, construction, decoration and repair. A large amount of construction waste will be generated during construction. The chaotic discarding of these construction wastes will not only take up a lot of space, but also cause waste of resources. In order to reduce the waste of resources, these construction wastes are usually recycled for a second time. When recycling construction waste, it is necessary to crush the construction waste through a crushing device. Crushing is a purely mechanical process operation. For solid raw materials that are too large to be used or semi-finished products that do not meet the requirements, they must be processed to make them smaller. This process is called crushing. The crushed construction waste is more convenient for storage and transportation, and the crushed construction waste is more convenient for further processing.

[0003] Existing patent: CN213254719U discloses an environmentally friendly waste recycling and processing device for construction, including a shell, a connecting mechanism, a crushing mechanism, a dust removal mechanism and a screening mechanism. Through the mutual cooperation of a dust removal pump, a water tank, a suction pipe, a fixed groove, a suction head, a protective net and a discharge pipe, it is convenient to handle the dust generated when the waste is crushed, and the dust is prevented from affecting the working environment and the health of workers. At the same time, the protective net protects the suction head to prevent the suction head from being hit by the waste, which greatly improves the service life. Through the mutual cooperation of the connecting groove, the buffer spring, the screen plate and the vibration motor, it is convenient to screen the crushed waste and avoid discharging large pieces of waste, which brings great convenience to the user.

[0004] This existing patent facilitates dust removal on the crushing device when crushing construction waste, but the crushing roller has a certain length and it is not convenient to adjust the feeding position, so that construction waste is easily accumulated on the crushing roller, making it difficult for the crushing roller to quickly crush the upper layer of construction waste, thereby affecting the crushing efficiency. In addition, some construction waste is wet due to rainy days when it is piled up and stored, so that moisture inside the construction waste accumulates in the crushing device when it is crushed. The long-term accumulation of moisture can easily cause mold and rust inside the crushing device, thereby affecting the service life of the crushing device. Summary of the invention

DETAILED DESCRIPTION

[0029] In order to further explain the technical solution of the present invention, it is described in detail below through specific embodiments.

[0030] like Figure 1As shown, the present invention provides an environmentally friendly waste secondary recycling and pulverizing device, comprising a motor 1, a pulverizing roller 2, a feed hopper 3, a discharge pipe 7 and a dust suction pipe 9, the motor 1 is installed on the left end surface of the pulverizing box 5, and the output shaft at the right end of the motor 1 passes through the left end surface of the pulverizing box 5 and is connected to the pulverizing roller 2, the pulverizing roller 2 is rotatably installed in the middle of the right end surface inside the pulverizing box 5, and the pulverizing teeth on the pulverizing roller 2 are staggered with the fixed teeth 4, the feed hopper 3 is embedded in the middle of the top end surface of the pulverizing box 5, the fixed teeth 4 are arranged on the inner end surface of the pulverizing box 5, a fixing frame 6 is installed at the bottom of the pulverizing box 5, and a discharge pipe 7 for discharging pulverized materials is arranged in the middle of the bottom end surface of the pulverizing box 5, the discharge pipe 7 runs through the middle of the bottom end surface of the pulverizing box 5, and the dust suction pipe 9 runs through the side surface of the pulverizing box 5, and is used to connect an external dust suction device to perform dust removal on the pulverized phase 5;

[0031] Specifically, the crushing roller 2 can be driven to rotate by starting the motor 1, and the end of the dust suction pipe 9 is connected to the external dust suction device, and then the construction waste to be crushed can be introduced into the crushing box 5 through the feed hopper 3. After entering the inner side of the crushing box 5, the construction waste contacts the crushing roller 2, so that the crushing roller 2 cooperates with the fixed teeth 4 to crush the construction waste. The crushed construction waste is discharged outward through the discharge pipe 7. At the same time, the dust generated during the crushing process of the construction waste is absorbed by the external dust suction device in cooperation with the dust suction pipe 9, so as to reduce the dust pollution to the environment and realize a more environmentally friendly crushing of the construction waste.

[0032] like Figure 2 As shown, in this embodiment, the reinforcing mechanism 8 is arranged inside the crushing box 5, and the reinforcing mechanism 8 includes a guide plate 81, a rotating shaft 82, a positioning block 83, a drying mechanism 84, a rotating mechanism 85 and an exhaust mechanism 86. The guide plate 81 is rotatably connected to the middle and lower part of the inner side of the feed hopper 3 through the rotating shaft 82, and a positioning block 83 for auxiliary support is arranged on the outer side of the guide plate 81, which is used to disperse the construction waste introduced into the feed hopper 3 onto the crushing roller 2;

[0033] The rotating shaft 82 vertically penetrates the rear end surface of the inner side of the feed hopper 3, and is used to drive the guide plate 81 to rotate when the rotating shaft 82 rotates. Two positioning blocks 83 are installed on the inner end surface of the feed hopper 3, and the two positioning blocks 83 are respectively located at the left and right ends of the inner side of the feed hopper 3, and are used to provide auxiliary support for the guide plate 81.

The rotating mechanism 85 is arranged at the outer rear end of the rotating shaft 82, and the exhaust mechanism 86 is arranged at the top of the right side of the crushing box 5, and is used to guide the hot air in the crushing box 5 outward.

[0034] In this embodiment, the bottom end surface of the guide plate 81 is higher than the top end surface of the crushing roller 2, and the maximum swing amplitude of the guide plate 81 corresponds to the two positioning blocks 83, so as to prevent the guide plate 81 from colliding with the crushing roller 2 when rotating, and at the same time facilitate the positioning blocks 83 to provide stable support for the guide plate 81;

[0035] Specifically, the guide plate 81 is driven by the rotating shaft 82 to swing left and right in the hopper 3 to disperse the construction waste onto the crushing roller 2 , thereby reducing the accumulation of construction waste on the crushing roller 2 .

[0036] like Figure 3 and Figure 4 As shown, in this embodiment, the drying mechanism 84 includes a fixed frame 841, a first filter 842 installed inside the fixed frame 841, a blower 843, an electric heating pipe 844 and a second filter 845. The fixed frame 841 is embedded in the left bottom of the crushing box 5. The first filter 842, the blower 843, the electric heating pipe 844 and the second filter 845 are sequentially distributed from left to right in the fixed frame 841, so that the blower 843 cooperates with the electric heating pipe 844 to form hot air to dry the inside of the crushing box 5, and the second filter 845 protects the blower 843 from dust.

[0037] Specifically, by turning on the air blower 843 and the electric heating tube 844, the air blower 843 cooperates with the electric heating tube 844 to generate hot air, and the hot air is transported to the inside of the crushing box 5, thereby heating and drying the residual moisture on the inside of the crushing box 5 and the outside of the crushing roller 2, reducing the residual moisture in the crushing device, and reducing the mold and rust caused by moisture accumulation inside the crushing device.

[0038] like Figure 5 As shown, the rotating mechanism 85 in this embodiment includes a fixed box 851, a partition 852 locked and fixed to the U-shaped structure in the middle of the inner side of the fixed box 851, a sliding hole 853 opened on the partition 852, a moving mechanism 854 arranged at the rear end of the partition 852 for driving the transmission block 855 to move left and right, and a transmission block 855 slidably installed on the inner side of the sliding hole 853. The transmission block 855 can move horizontally along the inner side of the sliding hole 853, so that the transmission block 855 drives the transmission frame 856 to rotate when it moves horizontally. The fixed box 851 is locked and fixed to the rear end surface of the feed hopper 3, and the transmission block 855 is movably extended into the inner side of the transmission frame 856 to cooperate with the moving mechanism 854 to drive the transmission frame 856 to swing left and right. The bottom of the front end surface of the transmission frame 856 is connected to the outer rear end of the rotating shaft 82, and the transmission frame 856 is rotatably connected to the bottom of the front end surface of the partition 852.

[0039] The bottom of the rear end face of the transmission frame 856 is rotatably connected to the bottom of the front end face of the partition 852 through a shaft, and the shaft and the rotating shaft 82 are coaxially arranged, so that the rotating shaft 82 can be driven to rotate stably when the transmission frame 856 rotates;

[0040] Specifically, the transmission block 855 moves horizontally along the slide hole 853 to drive the transmission frame 856 to rotate, and at the same time, the transmission frame 856 drives the rotating shaft 82 to rotate, and the rotating shaft 82 drives the guide plate 81 to rotate. During the rotation process of the guide plate 81, the construction waste dropped from the hopper 3 is guided to different positions on the crushing roller 2.

[0041] like Figure 6 As shown, in this embodiment, the moving mechanism 854 includes a speed regulating motor 8541, an eccentric wheel 8542, a groove 8543, a slide plate 8544 and a guide strip 8545. The speed regulating motor 8541 is locked and fixed to the rear end surface of the fixed box 851, and the front end output shaft of the speed regulating motor 8541 passes through the rear end surface of the fixed box 851. The front end output shaft of the speed regulating motor 8541 is connected to the inner ring of the eccentric wheel 8542 to drive the eccentric wheel 8542 to rotate. The eccentric wheel 8542 movably extends into the inner side of the strip-shaped groove 8543, so that the eccentric wheel 8542 cooperates with the groove 8543 when rotating to drive the slide plate 8544 to move horizontally.

[0042] The groove 8543 is vertically opened in the middle of the rear end face of the slide plate 8544, and the middle of the front end face of the slide plate 8544 is welded to the transmission block 855. The guide bar 8545 is an integrated structure arranged on the rear end face of the partition plate 852, and the guide bar 8545 is slidably connected to the inner side of the guide groove opened on the front end face of the slide plate 8544. Two guide bars 8545 are arranged on the rear end face of the partition plate 852, so that the slide plate 8544 can move horizontally along the guide bars 8545, thereby improving the stability of the slide plate 8544 during the movement process.

[0043] The transmission block 855 is a cylindrical structure, and the outer diameter of the transmission block 855 is smaller than the inner length of the sliding hole 853, so that the transmission block 855 can move stably and horizontally inside the sliding hole 853;

[0044] Specifically, by starting the speed regulating motor 8541, the eccentric wheel 8542 can be driven to rotate. During the rotation process of the eccentric wheel 8542, the groove 8543 is cooperated with the slide plate 8544 to move horizontally left and right at the rear end of the partition 852. At the same time, the slide plate 8544 drives the fixedly connected transmission block 855 to move back and forth left and right. The reciprocating movement of the transmission block 855 drives the transmission frame 856 to swing left and right, and the transmission frame 856 drives the guide plate 81 to swing back and forth left and right through the rotating shaft 82. The left and right swing of the guide plate 81 can disperse the construction waste to different positions on the crushing roller 2.

[0045] like Figure 7As shown, in this embodiment, the exhaust mechanism 86 includes an opening 861, a fixed cover 862 intersecting the inner side of the opening 861, an induced draft fan 863 locked and fixed to the inner side of the fixed cover 862, and an exhaust pipe 864 plugged into the right end of the inner side of the fixed cover 862 for air exhaust. The fixed cover 862 is locked and fixed to the top of the right end surface of the crushing box 5, and the exhaust pipe 864 runs through the top surface of the cold water tank 865. The bottom of the exhaust pipe 864 is higher than the cold water tank 865, and is used to introduce the hot air in the fixed cover 862 into the cold water tank 865. The cold water tank 865 is installed in the middle and upper part of the right end surface of the crushing box 5, and a drain pipe 866 for discharging sewage is provided at the bottom of the right end surface of the cold water tank 865, which is used to cool the introduced hot air and collect the introduced construction waste dust. A valve 867 is installed on the drain pipe 866;

[0046] In this embodiment, the inner right end of the fixed cover 862 is funnel-shaped, and the left end surface of the fixed cover 862 is an open structure, which facilitates the stable introduction of hot air in the fixed cover 862 into the exhaust pipe 864;

[0047] Specifically, the induced draft fan 863 is started to absorb the hot air and floating dust in the crushing box 5, and the hot air and dust are introduced into the cold water tank 865 through the fixed cover 862 and the exhaust pipe 864, so that the cold water pre-installed in the cold water tank 865 cools the hot air, and the cold water absorbs the dust discharged from the exhaust pipe 864. At the same time, the sewage in the cold water tank 865 can be discharged through the drain pipe 866 after the valve 867 is opened.
