Description

Technical Field

[0001] The invention relates to the technical field of drying equipment, and in particular to a hazardous waste drying treatment device. Background Art

[0002] With the development of social economy, the discharge of various wastes has increased, and the treatment of hazardous wastes has become a social problem. Before the hazardous wastes are treated, it is usually necessary to use a drying device for drying. In the medical and health fields, biomanufacturing fields, chemical product manufacturing fields and other related fields, a large amount of hazardous wastes will be generated due to production activities. These hazardous wastes generally include disposable sanitary products with bacteria and germs, heavy metal pollutants, and difficult-to-degrade pollutants. These pollutants are mostly wet garbage, which will produce leachate, corrode storage containers, and are very likely to leak. At present, in order to avoid damage to the environment caused by the leakage of hazardous wastes, drying treatment will be carried out before treatment. After drying, moisture is removed, the moisture content is reduced, and it is easier to carry out later treatment. At the same time, it also effectively prevents the generation of seepage and leakage. However, the existing hazardous waste drying treatment will cause the waste to produce a large amount of toxic and harmful gases and cause leakage during the heat treatment of the waste, which has great damage to the environment.

[0003] The Chinese patent with the patent publication number (CN221077166U) provides a hazardous waste treatment and drying device, including two sets of parallel bottom beams, a table connected between the right ends of the bottom beams, a high-frequency heater installed on the upper end of the table, a stand connected to the upper left end of the bottom beam, a drying chamber assembly, an adjustment assembly, a support assembly, a heat conduction assembly, an exhaust assembly, and a flue gas treatment assembly. The device uses the exhaust assembly and the flue gas treatment assembly arranged on the drying chamber assembly to pre-treat the toxic gases generated by drying before being discharged, thereby reducing damage to the environment and solving the problem that a large amount of toxic and harmful gases will be generated during the thermal treatment and drying of hazardous wastes, which are prone to leakage and thus damage the environmental ecology.

[0004] The above patent solves the problem of toxic and harmful gases during the heat treatment of hazardous waste. However, during the use of the device, since the hazardous waste contains moisture when it is put into the waste storage bin, the hazardous waste will immediately gather on the bottom plate of the waste storage bin and gather into piles. Although the waste storage bin in the above patent can rotate, the piled materials are still difficult to fully contact with the air, affecting the drying efficiency and prolonging the heating time, resulting in the waste not being heated evenly.

[0033] When the device is in operation, hazardous waste to be dried is firstly fed into the drying barrel 6 through the feeding port 14, the feeding port 14 is closed, and then the swing mechanism is operated, the swing output end drives the support shaft 4 to reciprocate, the reciprocating rotation of the support shaft 4 causes the support sleeve ring 3 to reciprocate, and then the support sleeve ring 3 drives the drying barrel 6 to reciprocate, and at the same time, a plurality of heating plates 7 in the drying barrel 6 are started to directly heat the hazardous waste in the barrel, and the hazardous waste is heated by the reciprocating swing of the drying barrel 6, so that the hazardous waste rolls back and forth in the drying barrel 6 like cooking, so that it is fully heated, and when the drying barrel 6 is reciprocatingly swinging, the dry air generator 41 generates dry air, and blows it into the drying barrel 6 through the blowing plate 8, so as to further disturb the hazardous waste in the drying barrel 6, improve the drying efficiency, save time, and the toxic gas generated during drying is purified by the gas filtering mechanism before being discharged, which plays an environmental protection role.

[0034] In order to show the detailed structure of the swing mechanism, the following features are also set:

[0035] The swing mechanism also includes a limiting slide rail 26, a transmission rack 27 and a power gear 5. The limiting slide rail 26 is fixedly arranged on the side wall of the frame 1, the transmission rack 27 is slidably connected to the limiting slide rail 26, the power gear 5 is coaxially fixedly connected to the support shaft 4, the power gear 5 is meshed with the transmission rack 27, and the swing output end is fixedly connected to the transmission rack 27.

[0036] When the device is running, the swing output end drives the transmission rack 27 to slide back and forth on the limiting slide rail 26, and the reciprocating sliding of the transmission rack 27 drives the power gear 5 to rotate back and forth, and the reciprocating rotation of the power gear 5 drives the support shaft 4 to rotate back and forth.

[0037] In order to show how the transmission rack 27 swings when the device is running, the following features are also specifically set:

[0038] The swing mechanism also includes a support bracket 23 (such as Fig.10 As shown in the figure, a reduction motor 24 fixedly arranged on the supporting bracket 23, a toggle plate 28 fixedly arranged in the middle of the transmission rack 27, return springs 35 symmetrically arranged on both sides of the toggle plate 28, a limiting vertical groove 29 opened on the toggle plate 28, a sliding sleeve 30 slidingly arranged in the limiting vertical groove 29, a swing column 31 coaxially rotatably arranged in the sliding sleeve 30, a swing plate 32 fixedly arranged at the end of the swing column 31 and a rotating sleeve rod 33 fixedly arranged at one end of the swing plate 32 away from the swing column 31, the rotating sleeve rod 33 is drivingly connected to the output shaft of the reduction motor 24, one end of the return spring 35 is fixedly connected to the toggle plate 28, and the other end is fixedly connected to the supporting bracket 23, and the axis of the rotating sleeve rod 33 is not colinear with the axis of the swing column 31.

[0039] When the device is running, the reduction motor 24 drives the rotating sleeve rod 33 to rotate, and the rotating sleeve rod 33 drives the swing plate 32 to rotate. The rotation of the swing plate 32 drives the swing column 31 to make a circular motion. The movement of the swing column 31 drives the sliding sleeve 30 to move together, so that the sliding sleeve 30 contacts the limiting vertical groove 29 and slides in the limiting vertical groove 29. As the swing plate 32 continues to drive the swing column 31 to move, the sliding sleeve 30 contacts the limiting vertical groove 29 and drives the toggle plate 28 to perform reciprocating linear motion. The movement of the toggle plate 28 drives the transmission rack 27 to perform reciprocating motion (it should be noted that during the above-mentioned toggle plate 28, the reset spring 35 adaptively contracts, and the reset spring 35 makes the movement of the toggle plate 28 smoother).

[0040] The toggle plate 28 is the swing output end of the swing mechanism.

[0041] In order to further prevent the waste in the drying barrel 6 from accumulating during the drying process, the following features are also specifically provided:

[0042] An arc-shaped rack 2 (such as Fig.11 As shown), a transmission gear ring 18 is coaxially fixedly arranged on the outer wall of the drying barrel 6, and the transmission gear ring 18 is engaged with the arc-shaped rack 2. The middle part of the drying barrel 6 is rotatably connected to the support ring 3 through a bearing.

[0043] When the support sleeve 3 drives the drying barrel 6 to swing, the reciprocating swinging operation of the drying barrel 6 will drive the transmission gear ring 18 to swing back and forth on the arc-shaped rack 2, and the transmission gear ring 18 engages with the arc-shaped rack 2 to rotate, thereby causing the drying barrel 6 to rotate back and forth, thereby achieving that when the support sleeve 3 drives the drying barrel 6 to swing back and forth, the drying barrel 6 can also reciprocate and rotate on its own, further preventing the accumulation of hazardous waste during drying.

[0044] In order to show the detailed structure of the air supply mechanism, the following features are also set:

[0045] The air delivery mechanism also includes a transfer cylinder 38 fixedly arranged on the frame 1, a piston rod 39 coaxially slidably arranged in the transfer cylinder 38, a bearing ring frame 19 coaxially fixedly arranged on one side of the support sleeve 3, a transfer gas ring 20 coaxially fixedly arranged on the bearing ring frame 19, and a gas delivery ring 21 coaxially rotatably arranged on the transfer gas ring 20 (such as Figure 6 As shown in FIG. 1 ), a connecting rod 36 fixedly arranged at the bottom of the toggle plate 28 and an elastic telescopic rod 37 fixedly arranged on the piston rod 39, each blowing plate 8 is provided with an air duct 10 (as shown in FIG. 1 ) at one end thereof close to the transfer air ring 20. Figure 7 As shown), each blowing plate 8 is provided with a plurality of air holes 9 in an evenly spaced linear array, a plurality of card slots 12 are provided in an annular shape on the bottom cover 11, a plurality of air supply ports 22 are provided in an annular shape on the air supply ring 21, the air supply port 22 passes through the card slot 12 and is communicated with the air duct 10, an air inlet and an air outlet are provided on the transfer cylinder 38, an air supply pipe 42 is provided on the dry air generator 41, the air supply pipe 42 is connected to the air inlet of the transfer cylinder 38, the air outlet of the transfer cylinder 38 is communicated with the inside of the transfer air ring 20 through the telescopic hose 40, one end of the elastic telescopic rod 37 is fixedly connected to the piston rod 39, and the other end is fixedly connected to the connecting rod 36.

[0046] When the toggle plate 28 reciprocates, the toggle plate 28 moves and drives the piston rod 39 to reciprocate through the elastic telescopic rod 37 (it should be noted that when the elastic telescopic rod 37 is stretched, it can continue to drive the piston rod 39 to move. When the elastic telescopic rod 37 is pushed by the toggle plate 28, the elastic telescopic rod 37 is in a compressed state. At this time, the elastic telescopic rod 37 is in hard contact with the piston rod 39). The piston rod 39 reciprocates and then sends the dry air generated by the dry air generator 41 into the transfer air ring 20. Thereafter, the gas enters the air delivery ring 21 from the transfer air ring 20, and finally enters the air duct 10 of the blowing plate 8 through the air supply port 22. It should be noted that each air hole 9 is a one-way air outlet structure. Through the above structure, when the device is running, dry air is intermittently blown out from the air hole 9, so that the hazardous waste in the drying barrel 6 can be blown and fully turned over to ensure that it can be evenly heated and accelerate the drying process.

[0047] In order to ensure that the reduction motor 24 can operate more safely when the device is running, the following features are also specifically set:

[0048] A first magnetic ring 25 is coaxially fixedly disposed on the output shaft of the reduction motor 24 , and a second magnetic ring 34 is coaxially fixedly disposed inside the rotating sleeve 33 . The first magnetic ring 25 and the second magnetic ring 34 are concentrically disposed.

[0049] When the device is running, the reduction motor 24 drives the first magnetic ring 25 to rotate, the rotation of the first magnetic ring 25 drives the second magnetic ring 34 to rotate, and the rotation of the second magnetic ring 34 drives the rotating sleeve 33 to rotate. The above structure refers to the magnetic coupler. By setting this structure, the reduction motor 24 is prevented from being damaged when the torque is too large.

[0050] In order to show the detailed structure of the gas filtration mechanism, the following features are also set:

[0051] An annular groove 15 is formed on the sealing cover 13 , and a plurality of air outlet holes 16 are formed on the annular groove 15 at equal intervals. A gas filter 17 is fixedly covered on the annular groove 15 .

[0052] It should be noted that the gas filter 17 can adsorb harmful substances in the gas generated during the drying process, and the gas filter 17 is provided with a substance that can react chemically with the toxic gas to purify the toxic gas. When the device is running, the toxic gas released in the drying barrel 6 is discharged through the air outlet 16, and then adsorbed and purified by the gas filter 17, and finally discharged into the air, so that the toxic gas is purified to prevent environmental pollution.

[0053] The working principle of the device is as follows: first, the hazardous waste to be dried is fed into the drying barrel 6 through the feeding port 14, the feeding port 14 is closed, the reduction motor 24 drives the first magnetic ring 25 to rotate, the first magnetic ring 25 rotates to drive the second magnetic ring 34 to rotate, the second magnetic ring 34 rotates to drive the rotating sleeve 33 to rotate, the rotating sleeve 33 drives the swing plate 32 to rotate, the swing plate 32 rotates to drive the swing column 31 to do a circular motion, the swing column 31 moves and then drives the sliding sleeve 30 to move together, so that the sliding sleeve 30 contacts the limiting vertical groove 29 and slides in the limiting vertical groove 29, and as the swing plate 32 rotates, the swing column 31 moves and then drives the sliding sleeve 30 to move together, so that the sliding sleeve 30 contacts the limiting vertical groove 29 and slides in the limiting vertical groove 29. 32 continuously drives the swing column 31 to move, and the sliding sleeve 30 contacts the limit vertical groove 29 to drive the toggle plate 28 to perform reciprocating linear motion. The movement of the toggle plate 28 drives the transmission rack 27 to perform reciprocating motion. The reciprocating motion of the transmission rack 27 drives the power gear 5 to rotate reciprocatingly. The reciprocating rotation of the power gear 5 drives the support shaft 4 to rotate reciprocatingly. The reciprocating rotation of the support shaft 4 causes the support collar 3 to swing reciprocatingly, and then the support collar 3 drives the drying barrel 6 to swing reciprocatingly. At the same time, the reciprocating swinging operation of the drying barrel 6 drives the transmission gear ring 18 to swing reciprocatingly on the arc-shaped rack 2. The transmission gear ring 1 8 meshing arc-shaped rack 2 rotates, which in turn causes the drying barrel 6 to reciprocate, so that when the support ring 3 drives the drying barrel 6 to swing back and forth, the drying barrel 6 can also reciprocate and rotate, and then the plurality of heating plates 7 in the drying barrel 6 are started to directly heat the hazardous waste in the barrel, and when the toggle plate 28 reciprocates, the toggle plate 28 drives the piston rod 39 to reciprocate through the elastic telescopic rod 37, and the piston rod 39 reciprocates to send the dry air generated by the dry air generator 41 into the transfer air ring 20, and then the gas is transferred from the transfer air ring 2 0 enters the air delivery ring 21, and finally enters the air duct 10 of the blowing plate 8 through the air supply port 22. It should be noted that each air hole 9 is a one-way air outlet structure. Through the above structure, when the device is running, dry air is intermittently blown out from the air hole 9, so that the hazardous waste in the drying barrel 6 can be blown and fully turned over to ensure that it can be evenly heated and accelerate the drying process. When the device is running, the toxic gas released from the drying barrel 6 is discharged through the air outlet 16, and then adsorbed and purified by the gas filter 17, and finally discharged into the air, so that the toxic gas is purified to prevent environmental pollution.

[0054] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
