DETAILED DESCRIPTION

[0040] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0041] See also Figure 1-Figure 10 The present invention provides a construction solid waste treatment device, including an outer frame 1 and a crushing mechanism arranged in the outer frame 1, the outer frame 1 includes two vertical and parallel side plates 11, the crushing mechanism includes a fixed jaw plate 2 fixedly assembled between the two side plates 11, a movable jaw plate assembly 3 and a driving device (not shown), both sides of the fixed jaw plate 2 and the movable jaw plate assembly 3 are tightly attached to the side plates 11, and the movable jaw plate assembly 3, the fixed jaw plate 2 and the two side plates 11 are surrounded to form a crushing chamber 4, and the cross-section of the crushing chamber 4 decreases continuously from top to bottom.

[0042] When in use, the driving device is started, and the driving device drives the movable jaw plate assembly 3 to make an eccentric movement relative to the fixed jaw plate 2. During the eccentric movement of the movable jaw plate assembly 3, the movable jaw plate assembly 3 cooperates with the fixed jaw plate 2 to gradually crush the solid waste in the crushing chamber 4 until it is crushed to a suitable size and discharged from the bottom of the crushing chamber 4.

[0043] like Figure 4 As shown, in this embodiment, the movable jaw plate assembly 3 is tilted, and the movable jaw plate assembly 3 includes a first eccentric shaft 5 rotatably connected to the top end of the movable jaw plate assembly 3 and a second eccentric shaft 6 rotatably connected to the bottom end of the movable jaw plate assembly 3, and the two rotating ends of the first eccentric shaft 5 and the second eccentric shaft 6 are rotatably assembled on the two side plates 11 respectively, and the driving device (not shown) is used to drive the first eccentric shaft 5 and the second eccentric shaft 6 to rotate synchronously.

[0044] This embodiment is based on the above-mentioned arrangement. When the driving device is started, the driving device drives the first eccentric shaft 5 and the second eccentric shaft 6 to rotate synchronously. During this process, the top and bottom ends of the movable jaw plate assembly 3 can move around the rotation center axis of the first eccentric shaft 5 and the rotation center axis of the second eccentric shaft 6 respectively, so that the movable jaw plate assembly 3 maintains an inclined posture and makes eccentric movement relative to the fixed jaw plate 2 to complete the impact crushing of the solid waste in the crushing chamber 4.

[0045] In order to improve the crushing efficiency of this device and take into account the technical requirements of crushing particle size, such as Figure 4-Figure 7 As shown, in this embodiment, the eccentricity of the first eccentric shaft 5 is greater than the eccentricity of the second eccentric shaft 6, the movable jaw assembly 3 includes an inner movable plate 73231 and an outer movable plate 73232 that is slidably matched with the inner movable plate 73231, the outer movable plate 73232 is located on the side of the inner movable plate 73231 away from the fixed jaw plate 2, and the outer movable plate 73232 can only slide on the outer movable plate 73232 along its length direction, the first eccentric shaft 5 is rotatably connected to the top of the inner movable plate 73231, and the second eccentric shaft 6 is rotatably connected to the bottom of the outer movable plate 73232. Figure 7 As shown, specifically, the top of the inner movable plate 73231 has a first axial hole 311 perpendicular to the side plate 11, and the bottom of the outer movable plate 73232 has a second axial hole 321 perpendicular to the side plate 11, the first eccentric shaft 5 is rotatably adapted in the first axial hole 311, and the second eccentric shaft 6 is rotatably adapted in the second axial hole 321.

[0046] Based on the above-mentioned arrangement, in this embodiment, when the driving device drives the first eccentric shaft 5 and the second eccentric shaft 6 to rotate synchronously, the top of the inner movable plate 73231 can make a first eccentric motion around the rotation center axis of the first eccentric shaft 5, and the bottom of the outer movable plate 73232 can make a second eccentric motion around the rotation center axis of the second eccentric shaft 6. Since the eccentricity of the first eccentric shaft 5 is greater than the eccentricity of the second eccentric shaft 6, when the movable jaw plate assembly 3 maintains an inclined posture and makes eccentric motion relative to the fixed jaw plate 2, the closer the movable jaw plate assembly 3 is to the upper end, the larger its swing angle is, and the closer it is to the lower end of the movable jaw plate assembly 3, the smaller its swing angle is. Therefore, the staff can reasonably design the eccentricity of the first eccentric shaft 5 and the second eccentric shaft 6 to improve the crushing efficiency of the device and take into account the requirements of the crushing particle size, that is, the device can increase the eccentricity of the first eccentric shaft 5 to increase the top movement distance of the movable jaw plate assembly 3, thereby increasing the impact force of the upper part of the movable jaw plate assembly 3 (when the rotation speed of the first eccentric shaft 5 is constant, the greater the eccentricity of the first eccentric shaft 5, the greater the movement speed of the movable jaw plate assembly 3, and the greater the impact force), so that the solid waste can be quickly crushed after entering the crushing chamber 4, thereby improving the crushing efficiency of the device; the device can reduce the eccentricity of the first eccentric shaft 5 to reduce the bottom movement distance of the movable jaw plate assembly 3, thereby avoiding the solid waste from falling out of the crushing chamber 4 before being crushed to a suitable particle size due to the large opening and closing distance at the bottom of the movable jaw plate assembly 3, so as to take into account the technical requirements of the crushing particle size.

[0047] It should be noted that the sliding fit design of the inner movable plate 73231 and the outer movable plate 73232 is designed so that when the eccentricities of the first eccentric shaft 5 and the second eccentric shaft 6 are different, the inner movable plate 73231 and the outer movable plate 73232 can slide relative to each other, so that the movable jaw plate assembly 3 can complete the eccentric movement described above relative to the fixed jaw plate 2.

[0048] In order to further improve the crushing efficiency of this device, Figure 4 As shown, the fixed jaw plate 2 is evenly provided with a third crushing strip 21 along the width direction of the side close to the movable jaw plate assembly 3, as shown in FIG. Figure 6-Figure 8 As shown, the first crushing bar 312 is evenly fixedly provided on one side of the inner movable plate 73231 close to the fixed jaw plate 2 along its width direction, and the first crushing bar 312 is evenly provided with a first flaring groove 313 along its length direction, a second crushing bar 322 is slidably provided between adjacent first crushing bars 312, and the second crushing bar 322 is evenly provided with a second flaring groove 323 along its length direction, a strip groove 314 is penetrated on the inner movable plate 73231 between adjacent first crushing bars 312, and the second crushing bar 322 is fixedly connected to the outer movable plate 73232 by slidingly fitting in the sliding block 315 in the strip groove 314.

[0049] This embodiment is based on the above-mentioned arrangement. When the movable jaw plate assembly 3 makes an eccentric movement relative to the fixed jaw plate 2, relative sliding will occur between the inner movable plate 73231 and the outer movable plate 73232. Correspondingly, the second shredding bar 322 and the first shredding bar 312 will also slide relative to each other. During this process, the first flared groove 313 of the first shredding bar 312 and the second flared groove 323 of the second shredding bar 322 cooperate to shear the solid waste, thereby further improving the crushing efficiency of the device.

[0050] Furthermore, the first eccentric shaft 5 and the second eccentric shaft 6 rotate in opposite directions, and the first eccentric shaft 5 and the second eccentric shaft 6 rotate at the same speed. Based on the above design, when the movable jaw assembly 3 makes an eccentric movement relative to the fixed jaw 2, the relative sliding distance between the inner movable plate 73231 and the outer movable plate 73232 can be increased to enhance the shearing effect of the first flared groove 313 of the first shredding bar 312 and the second flared groove 323 of the second shredding bar 322 on the solid waste, thereby further enhancing the crushing efficiency of the device.

[0051] like Figure 1 and Figure 2 As shown, in the embodiment, the outer frame 1 also includes a connecting plate 12 disposed between one side of the two side plates 11, the connecting plate 12 and the two side plates 11 form a U-shaped structure, the bottom of the connecting plate 12 is also provided with a storage plate 13 extending horizontally toward the side away from the side plates 11, a counterweight body 14 is provided on the storage plate 13, and a guide plate 15 is also obliquely provided between the two side plates 11 directly below the crushing chamber 4. Based on the above design, the guide plate 15 can discharge the crushed solid waste in the crushing chamber 4 from the side of the outer frame 1 away from the connecting plate 12, and the counterweight body 14 can increase the overall weight of the device to avoid the device from being offset due to vibration during the crushing of fixed waste.

[0052] like Figure 4 As shown, in this embodiment, the fixed jaw plate 2 includes a vertical portion 22 and an inclined portion 23 connected to the bottom of the vertical portion 22, and the inclined portion 23 is consistent with the inclined direction of the fixed jaw plate 2. Based on the above design, the crushing chamber 4 can be divided into an upper chamber 41 and a lower chamber 42, wherein the upper chamber 41 corresponds to the vertical portion 22 of the fixed jaw plate 2, and the lower chamber 42 corresponds to the inclined portion 23 of the fixed jaw plate 2. During the crushing process, the cross-section of the lower chamber 42 is smaller, which prolongs the residence time of the fixed waste in the lower chamber 42, thereby ensuring that the fixed waste can be crushed to a suitable particle size.

[0053] like Figure 4In this embodiment, the construction solid waste treatment device further includes a dust removal mechanism, which includes a dust cover 71, a dust suction channel 72, and a telescopic component 73 arranged between an inner movable plate 73231 and an outer movable plate 73232; the dust cover 71 is fixedly arranged on the top of the outer frame 1, and the input end of the dust suction channel 72 passes through the dust cover 71 and extends to a position above the crushing chamber 4 and is fixedly connected with the dust cover;

[0054] like Figure 4 and Figure 5 As shown, the telescopic assembly 73 is located on the side of the outer movable plate 73232 away from the inner movable plate 73231. The telescopic assembly 73 includes a box body 731 fixed on the outer movable plate 73232, a movable plate 732 slidably arranged in the box body 731, and a pair of movable rods 733 vertically arranged on the top of the movable plate 732. The top ends of the movable rods 733 penetrate the box body 731 and are fixedly connected to the inner movable plate 73231 through a connecting piece. An air inlet pipe 734 and an air outlet pipe 735 are respectively arranged at the bottom of the box body 731, and a first one-way valve 736 and a second one-way valve 737 are respectively arranged on the air inlet pipe 734 and the air outlet pipe 735.

[0055] like Figure 4 As shown, the dust suction channel 72 is provided with an air jet pipe 738 at the center position near one end of the dust suction cover. Fig. 9 As shown, the output end of the jet pipe 738 faces the side away from the dust hood, and the input end of the jet pipe 738 is connected to the outlet pipe 735 through a connecting pipe 739. Fig.10 As shown, the connecting pipeline 739 includes a hose section 7391 and a hard pipe section 7392 .

[0056] Based on the above design, this embodiment can make the movable plate 732 reciprocate in the box body 731 during the relative sliding of the inner movable plate 73231 and the outer movable plate 73232, so that the gas continuously enters the box body 731 and is discharged from the air outlet pipe 735. The gas discharged from the air outlet pipe 735 can enter the dust suction channel 72 through the connecting pipe 739, so that a negative pressure is formed in the dust suction channel 72 (Bernoulli principle), and then the dust in the crushing chamber 4 is sucked into the dust suction channel 72 through the dust suction hood, thereby preventing the dust generated by the crushing of fixed waste from floating around and polluting the working environment.

[0057] like Fig. 9As shown, in this embodiment, the counterweight body 14 includes a counterweight box 141, tap water is stored in the counterweight box 141, a drain pipe 142 is provided at the bottom of the counterweight box 141, and a valve 143 is provided on the drain pipe 142. When the device is performing a crushing operation, the counterweight of the device can be increased by adding tap water to the counterweight box 141, and when the device is moved, the tap water in the counterweight box 141 can be drained through the drain pipe 142, thereby reducing the overall weight of the device and facilitating the movement of the device.

[0058] Furthermore, an exhaust port 144 is provided at the top of the counterweight box 141, and the output end of the dust suction channel 72 extends into the box body 731, and there is a slight gap between the output end of the dust suction channel 72 and the tap water level, and the gap is 2cm-6cm. Based on the above design, the dust sucked by the dust suction channel 72 can be sent into the counterweight box 141, and the dust is absorbed by the tap water.

[0059] In this embodiment, the driving device includes a first motor (not shown) and a second motor (not shown), and the output ends of the first motor and the second motor are respectively connected to the first eccentric shaft 5 and the second eccentric shaft 6 through a pulley mechanism.

[0060] The present invention also provides a method for treating a construction solid waste device, comprising the following steps:

[0061] S1: Add tap water to the counterweight box 141 through the exhaust port 144 until the distance between the liquid level in the counterweight box 141 and the output end of the dust suction channel 72 is 2 cm-6 cm;
