Description

Technical Field

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

[0002] A drying device is a device that uses heat energy or other methods to remove moisture from objects. It is widely used in household, industrial, agricultural, medical and other fields. A drying device is needed for the subsequent treatment of some wastes generated in wastewater filtration. The filtered waste is dried by the drying device, so that subsequent treatment can be better carried out and the pollution of the environment by the waste is reduced.

[0003] A Chinese patent with the authorization announcement number CN205690866U discloses a drying device for treating wet waste by heat exchange, including cylinders that are nested to form an airflow channel and perform heat exchange, and the cylinders are provided with through holes for heat exchange. The cylinders that are nested to form an airflow channel and perform heat exchange can guide the hot air in the drying device to flow regularly and evenly, so that the wet waste is heated evenly, the drying efficiency is improved, and the drying time is shortened; the through holes for heat exchange provided on the cylinder can promote heat exchange, facilitate the hot air to transfer heat to the radioactive wet waste, and at the same time transfer the moisture in the radioactive wet waste to the hot air to be carried out of the drying device by the hot air flow, further improving the drying efficiency, and the through holes also reduce the weight of the drying device.

[0004] The above patent document guides the hot air in the drying device to flow regularly and evenly, so that the wet waste is heated evenly, thereby improving the drying efficiency. However, when drying the accumulated waste, the traditional drying method is still to use hot air or a heat transfer plate to gradually penetrate from the outer layer of the waste to the inner layer of the material for drying. As the waste is dried, the waste is easily dried on the heat transfer plate, which can easily lead to low drying efficiency and increase the drying time. Summary of the invention

[0010] The effect is that the driving assembly can rotate the drying plate to an inclined state, and the inclined drying plate can make the waste move with the action of gravity during the drying process, reduce the adhesion caused by staying in a certain position for too long, and ensure the heat conduction efficiency of the drying plate.

The drying plate can dry the accumulated waste in layers, and at the same time prevent the waste from drying and sticking to the drying plate after losing water, thereby ensuring the thermal conductivity of the drying plate and improving the waste drying efficiency and effect.

[0020] When the scraper rotates to the push rod position, the push rod will push the scraper to scrape off the dried and scattered waste on the surface of the drying plate. When the scraper moves to the baffle position, the push rod will shrink inward due to the inclined surface on the scraper, and then push and scrape the next scraper, thereby improving the thermal conductivity of the drying plate and ensuring the drying efficiency and effect.

[0021] The output end of the driving motor is transmission connected to one of the rotating rods, and one end of the other rotating rod is rotationally connected to the vertical plate.

DETAILED DESCRIPTION

[0032] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0033] like Figures 1 to 9 As shown, a drying device for waste treatment of the present invention comprises: a support plate 10, a barrel 20, a variable pitch screw 22, a layering mechanism, a scraper 42 and a driving assembly, the barrel 20 is rotatably arranged above the support plate 10, the barrel 20 can be in an inclined state during drying, so that the moisture generated by the waste drying can have a smoother discharge space, the variable pitch screw 22 is rotatably arranged in the barrel 20, the multi-component layering mechanism is axially arranged on the outer peripheral surface of the variable pitch screw 22, and the multi-component layering mechanism can be evenly diffused and moved along the axial direction of the variable pitch screw 22, so that the waste is discharged. The waste is dried in layers, and each group of stratified mechanisms is composed of four drying plates 40. The driving component is arranged on the outer peripheral surface of the variable pitch screw 22, and the driving component can make the drying plates 40 rotate along the circumference of the cylinder 20. The driving component can also drive the drying plates 40 to flip from horizontal to inclined. The drying plates 40 are arranged inclined to prevent the waste from drying on the drying plates 40 during layered drying, affecting the drying efficiency. A scraper 42 is slidably arranged on the upper and lower surfaces of each drying plate 40, and the scraper 42 can scrape off the dried waste on the drying plate 40 to improve the thermal conductivity of the drying plate 40.

[0034] When the waste is dried, the variable pitch screw 22 can move the multi-component stratified mechanism upward in a uniform manner, so that the stratified mechanism has a certain spacing distance, and the spacing distance can be adjusted according to the amount of waste, so as to ensure the drying efficiency of different amounts of waste. Then the driving component makes the drying plate 40 flip from horizontal to inclined, and then the waste is poured into the interior of the cylinder 20. Since the drying plate 40 is in an inclined setting, the waste can fall to the inner bottom of the cylinder 20 through the gap of the drying plate 40. Then the driving component can drive the stratified mechanism to rotate along the circumference of the cylinder 20. After a certain stirring of the waste, the drying plate 40 is tilted at the same time. The drying plate 40 can dry the accumulated waste in layers, and at the same time prevent the waste from drying and solidifying on the drying plate 40 after the water is lost. At the same time, for the thermal conductivity of the drying plate 40, the scraper 42 can clean the thermal conductive surface of the drying plate 40, so as to clean up the waste debris partially dried on the drying plate 40, thereby improving the drying efficiency.

[0035] like Figures 2 to 4 As shown, a partition 21 is rotatably provided inside the cylinder 20, a motor 29 is provided on the inner bottom wall of the cylinder 20, and the output end of the motor 29 is connected to the bottom surface of the partition 21, a top plate is rotatably provided on the top of the cylinder 20, a motor 28 is provided on the top of the top plate, a variable pitch screw 22 is rotatably provided between the bottom surface of the top plate and the top surface of the partition 21, and the output end of the motor 28 is transmission-connected to the variable pitch screw 22, a guide rod 23 is fixedly provided on the top of the partition 21, and the top end of the guide rod 23 is fixedly connected to the top plate.

[0036] When the waste is dried, the motor 28 can drive the variable pitch screw 22 to rotate, and the rotation of the variable pitch screw 22 can drive the stratification mechanism to move in the axial direction, so that the waste can be dried in layers and the drying efficiency can be improved. At the same time, the guide rod 23 can make the stratification mechanism more stable when moving. When the motor 1 29 drives the partition 21 to rotate, since the guide rod 23 is fixedly connected to the partition 21 and the top plate, the rotation of the partition 21 drives the top plate to rotate, and the rotation of the top plate drives the motor 2 28 and the variable pitch screw 22 to rotate as a whole, so that the stratification mechanism can rotate along the circumference of the cylinder 20, so that the stratification mechanism can stir the waste, and at the same time facilitate the subsequent cleaning of the surface of the drying plate 40 to ensure the cleaning efficiency of the drying plate 40.

[0037] like Figure 3 to Figure 4As shown, the stratification mechanism includes: drying plates 40, a group of stratification mechanisms has four drying plates 40, the drying plates 40 are circumferentially spaced along the outer circumferential surface of the variable pitch screw 22, and there is a certain gap between two adjacent drying plates 40 to avoid interference between adjacent drying plates 40 when turning over. A heating element is arranged inside the drying plate 40. In this embodiment, the heating element is a heating rod. The heating rod heats the drying plate 40 to dry the waste, and an annular heating ring is arranged on the inner ring surface of the cylinder 20. The waste can be stratified by the drying plate 40 so that the heat is dried by the inner and outer layers at the same time, thereby improving the drying efficiency.

[0038] like Figures 3 to 6 As shown, the driving assembly includes: a movable sleeve 24, a rotating cylinder 1 25 and a rotating cylinder 26. The movable sleeve 24 is sleeved on the outer circumference of the variable pitch screw 22, and the movable sleeve 24 cooperates with the variable pitch screw 22 to enable multiple layered mechanisms to move evenly and diffusely. Two guide holes are provided on the movable sleeve 24, and the guide rod 23 passes through the guide holes to make the movable sleeve 24 move more stably. The rotating cylinder 1 25 and the rotating cylinder 26 are rotatably arranged on the movable sleeve 24. The outer circumference of the rotating cylinder 1 25 is rotatably arranged with a rotating rod 27, and the rotating rods 27 are circumferentially spaced along the outer circumference of the rotating cylinder 1 25. One end of the rotating rod 27 passes through the outer circumference of the rotating cylinder 26, and the end of the rotating rod 27 that passes through is fixedly connected to the drying plate 40, and the rotating rod 27 corresponds to the drying plate 40 one by one.

[0039] A bevel gear ring 30 is provided on the movable sleeve 24, a bevel gear 31 is provided on the outer circumferential surface of each rotating rod 27, and the bevel gear 31 is meshed with the bevel gear ring 30, a bevel gear ring 2 32 is provided on the top of the rotating cylinder 25, a driving motor 50 is provided on the top of the movable sleeve 24, a bevel gear 2 51 is provided on the output end of the driving motor 50, and the bevel gear 2 51 is meshed with the bevel gear ring 2 32.

[0040] The inclined drying plate 40 can make the waste move with the action of gravity during the drying process, and reduce the adhesion caused by staying in a certain position for too long. The driving motor 50 drives the bevel gear 2 51 to rotate. Since the bevel gear 2 51 is meshed with the bevel gear ring 2 32, the rotation of the bevel gear 2 51 drives the rotating drum 1 25 to rotate, and the rotation of the rotating drum 1 25 drives the rotating rod 27 to rotate circumferentially. The circumferential rotation of the rotating rod 27 drives the rotating drum 2 26 and the drying plate 40 to rotate circumferentially along the outer peripheral surface of the variable pitch screw 22. At the same time, the bevel gear 1 31 is meshed with the bevel gear ring 1 30. Therefore, the rotating rod 27 rotates axially while rotating circumferentially along the outer peripheral surface of the variable pitch screw 22, so that the drying plate 40 rotates circumferentially and rotates axially at the same time, thereby realizing the inclined setting of the drying plate 40. As the drying time changes, the inclination angle also changes accordingly, so as to prevent the waste from drying on the surface of the drying plate 40, thereby ensuring the efficiency and effect of drying.

[0041] Although the inclined setting of the drying plate 40 can improve the waste drying effect, thereby ensuring the thermal conductivity of the drying plate 40, there will still be some scattered waste that will dry on the surface of the drying plate 40. In order to ensure the drying efficiency and effect, the scraper 42 can scrape off the scattered waste that has dried on the drying plate 40 to improve the thermal conductivity of the drying plate 40.

[0042] like Figures 7 to 9 As shown, the scraper 42 is slidably arranged on the upper and lower surfaces of the drying plate 40, and each drying plate 40 is provided with a guide bar 1 41 and a guide bar 2 44 on the upper and lower surfaces, the guide bar 1 41 and the guide bar 2 44 are arranged in an arc shape, and the radius of the guide bar 1 41 is larger than the guide bar 2 44, and the scraper 42 is slidably matched with the guide bar 1 41 and the guide bar 2 44, so that the scraper 42 can slide circumferentially along the outer peripheral surface of the drying plate 40, the end surface of the scraper 42 is an isosceles trapezoidal surface, and the scraper 42 has two inclined surfaces, and the outer peripheral surface of the cylinder 20 is A top extension rod 80 and a second top extension rod 81 are arranged on the circumferential surface. Both the top extension rod 80 and the second top extension rod 81 are composed of an electric telescopic rod and a top rod, and the top rod is two sections elastically arranged at the same time. The top extension rod 80 and the second top extension rod 81 are arranged in an eight-shaped shape. The top extension rod 80 and the second top extension rod 81 can push the scraper 42 and can scrape off the scattered waste on the surface of the drying plate 40. Baffles 43 are arranged at the end positions on both sides of the guide bar 1 41 and the guide bar 2 44. The baffle 43 is used to intercept the scraper 42 to prevent the scraper 42 from slipping out.

[0043] When the surface of the drying plate 40 is to be scraped, the driving assembly first drives the drying plate 40 to flip into a horizontal state so that the drying plate 40 is parallel to the top plate, and then the ends of the top extension rod 1 80 and the top extension rod 2 81 are extended toward the inside of the cylinder 20, and the top rods on the top extension rod 1 80 and the top extension rod 2 81 are in contact with the top surface and the bottom surface of the drying plate 40 respectively. Then, when the motor 1 29 drives the partition 21 to rotate, since the guide rod 23 is fixedly connected to the partition 21 and the top plate, the rotation of the partition 21 drives the top plate to rotate, and the rotation of the top plate drives the motor 2 28 and the variable pitch screw 22 to rotate as a whole, so that the drying plate 40 can rotate along the circumferential direction of the cylinder 20, and the drying plate 40 rotates. The scraper 42 is driven to rotate. When the scraper 42 rotates to the push rod position, the push rod will push the scraper 42 to scrape off the dried and scattered waste on the surface of the drying plate 40. When the scraper 42 moves to the baffle 43 position, due to the inclined surface on the scraper 42, the push rod retracts inward, and then pushes and scrapes the next scraper 42, thereby improving the thermal conductivity of the drying plate 40 and ensuring the drying efficiency and effect. After cleaning a group of stratification mechanisms, the push rod 1 80 and the push rod 2 81 will retract to the outside of the cylinder 20, and the variable pitch screw 22 will drive the next group of stratification mechanisms to move to this position, and then clean it. The principle is the same as the above, so it will not be repeated.

[0044] like Figure 1 to Figure 2 As shown, an exhaust port 90 is provided on the outer peripheral surface of the cylinder 20, and the exhaust port 90 can discharge the moisture generated in the process of drying the waste. At the same time, the inclined setting of the cylinder 20 during drying can increase the space for moisture circulation and improve the dehumidification efficiency. A feed port 91 is provided on the outer peripheral surface of the cylinder 20, and a cover plate is provided on the top of the feed port 91 to reduce heat loss during drying. Two vertical plates 11 are provided on the top wall of the support plate 10, and the two vertical plates 11 are located on both sides of the cylinder 20. A driving motor 12 is provided on the outer wall of one of the vertical plates 11. A rotating rod 13 is provided on the outer peripheral side of the cylinder 20, and the output end of the driving motor 12 is transmission-connected to one of the rotating rods 13, and one end of the other rotating rod 13 is rotationally connected to the vertical plate 11. The driving motor 12 can drive the rotating rod 13 to rotate, and the rotation of the rotating rod 13 drives the cylinder 20 to rotate, so that the cylinder 20 is tilted, thereby avoiding the drying of waste and ensuring the drying efficiency.
