Description

Technical Field

[0001] This utility model belongs to the field of waste treatment technology, specifically relating to a waste drying device for waste incineration power plants. Background Technology

[0002] Currently, the most common method of waste disposal is still incineration, which uses the heat generated during incineration to generate electricity and achieve energy recovery and conversion. In order to reduce the pollution generated by incinerating waste, especially gaseous pollution, the waste is often dried before incineration to reduce the moisture content of the waste.

[0003] Currently, most common waste drying methods use light lamps or hot air. The former is inefficient and ineffective when dealing with large amounts of waste, while the latter still fails to properly dry some waste with high water absorption rates. Utility Model Content

[0004] The purpose of this utility model is to provide a waste drying device for waste incineration power plants.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] A waste drying device for a waste incineration power plant includes a base and a control panel. The base is installed on the ground and has a recessed cavity corresponding to the base on the lower side of the ground. The base is equipped with a drying mechanism.

[0007] The drying mechanism includes a compression component and a drying component. The compression component is located on the upper end of the base, and the drying component is located in the recessed cavity and corresponds to the base. The compression component includes a column, a slide rail, and a compressor. The column is connected to the upper end of the base and there are two columns, which are symmetrically distributed relative to the recessed cavity. There are two slide rails, which are respectively located at the opposite ends of the two columns. The compressor is connected to the two slide rails.

[0008] The drying assembly includes a shroud, a water filter tray, a drying tray, and exhaust columns. The shroud is connected to the lower end of the compressor. The water filter tray is annular and fixedly installed in the opening of the corresponding recessed cavity of the base. The drying tray and the water filter tray are concentrically arranged to form a closed opening structure of the recessed cavity. There are several exhaust columns evenly distributed on the upper end of the drying tray. The exhaust columns are connected to the air passage of an external hot air mechanism through air pipes. The water filter tray has several drainage holes evenly distributed. The shroud is connected to the compressor.

[0009] The compressor includes a bracket, a cylinder, and an extrusion disc. The bracket and two columns are connected to a slide rail via a slider. The slide rail is an electrically controlled slide rail and is connected to the control panel via electrical signals. The cylinder is fixedly mounted on the upper end of the bracket. The extrusion disc is located on the lower side of the bracket and is connected to the output shaft of the cylinder. The extrusion disc is concentrically aligned with the cover and is slidably mounted inside the cover. The cover is fixedly connected to the bracket. The highest horizontal height of the extrusion disc is greater than the height of the upper opening of the cover.

[0010] The lower end of the base is also provided with a water receiving cover corresponding to the water filter tray, and the lower end of the water receiving cover is provided with a drain pipe connected to the external liquid circuit.

[0011] An adjustment assembly is provided between the drying tray and the base. When the adjustment assembly is provided, the water filter tray and the drying tray are rotatably sealed. The adjustment assembly includes a motor and an air distribution hood. The lower end of the drying tray extends downward into the recessed cavity. An air groove is opened on the lower side of the drying tray, which is connected to several exhaust columns. The air distribution hood is rotatably sealed to the lower side of the drying tray. The air groove is connected to the air distribution hood. The air distribution hood is connected to the air path of the external hot air mechanism. The output shaft of the motor is concentrically connected to the drying tray. Both the air distribution hood and the motor are fixedly connected to the inner wall of the recessed cavity through connecting rods.

[0012] The exhaust column has several one-way exhaust ports on its side that communicate with the air groove.

[0013] The upper part of the drying tray has a frustum structure with a diameter that gradually increases from top to bottom.

[0014] The present invention has at least the following advantages compared to the prior art:

[0015] The combination of the compression and drying components allows for the initial compression of waste during the drying process. This process removes water from the waste and creates a closed space through which hot air is introduced, thus drying the waste and making it more suitable for subsequent incineration, reducing black smoke production during combustion. The adjustable components further enhance the drying process, preventing the waste density after compression and drainage from becoming too high, which could hinder the effective flow of hot air for drying.

Detailed Implementation

[0023] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] like Figure 1-5 As shown, a waste drying device for a waste incineration power plant includes a base 1 and a control panel. The base 1 is installed on the ground and a recessed cavity 11 corresponding to the base 1 is opened on the lower side of the ground. The base 1 is equipped with a drying mechanism.

[0025] The drying mechanism includes a compression component and a drying component. The compression component is located on the upper end of the base 1, and the drying component is located in the recessed cavity 11 and corresponds to the base 1. The compression component includes a column 2, a slide rail 21 and a compressor. The column 2 is connected to the upper end of the base 1 and there are two columns, which are symmetrically distributed relative to the recessed cavity 11. There are two slide rails 21 and they are respectively located at the opposite ends of the two columns 2. The compressor is connected to the two slide rails 21.

[0026] The drying assembly includes a shroud 22, a water filter tray 3, a drying tray 31, and exhaust columns 32. The shroud 22 is connected to the lower end of the compressor. The water filter tray 3 is annular and fixedly installed in the opening of the corresponding recessed cavity 11 of the base 1. The drying tray 31 and the water filter tray 3 are concentrically arranged to form a closed opening structure of the recessed cavity 11. There are several exhaust columns 32, which are evenly arranged on the upper end of the drying tray 31. The exhaust columns 32 are connected to the air passage of the external hot air mechanism through air pipes. The water filter tray 3 has several drainage holes 33 evenly opened. The shroud 22 is connected to the compressor.

[0027] When drying the garbage, first use the control panel to control the slide rail 21 to move the compressor down until the cover 22 abuts against the base 1. At this time, the garbage can be loaded into the cover 22. When the appropriate compression capacity is reached, the compressor is turned on to squeeze the garbage, so that the water in the garbage is squeezed out. The squeezed water flows downward until it is discharged to the outside through the filter plate 3, thereby initially reducing the water content in the garbage.

[0028] Then, hot air from the external hot air mechanism is input through the control panel. At this time, the hot air is input into the garbage inside the hood 22 through the exhaust column 32, and the hot air is used to dry the garbage inside the hood 22, thereby further removing the moisture from the garbage. The cooperation of the hood 22, the base 1 and the compressor can form a relatively closed space, which can heat up the garbage more effectively and quickly, improving the drying effect and efficiency. Compared with the traditional method of directly drying garbage, this can effectively improve the efficiency and effect of garbage drying, and avoid prolonged drying time and poor drying effect caused by excessive water absorption in some sponge-like garbage.

[0029] The compressor includes a bracket 4, a cylinder 41, and an extrusion disc 42. The bracket 4 and two columns 2 are connected to a slide rail 21 via a slider. The slide rail 21 is an electrically controlled slide rail 21 and is connected to the control panel via electrical signals. The cylinder 41 is fixedly mounted on the upper end of the bracket 4. The extrusion disc 42 is located on the lower side of the bracket 4 and is connected to the output shaft of the cylinder 41. The extrusion disc 42 is concentrically aligned with the cover cylinder 22 and is slidably mounted inside the cover cylinder 22. The cover cylinder 22 is fixedly connected to the bracket 4. The highest horizontal height of the extrusion disc 42 is greater than the height of the upper opening of the cover cylinder 22.

[0030] The lower end of the base 1 is also provided with a water receiving cover 5 corresponding to the water filter tray 3, and the lower end of the water receiving cover 5 is provided with a drain pipe 51 connected to the external liquid circuit.

[0031] When compressing and draining the waste, the slide rail 21 is started by controlling the control panel. The slide rail 21 can be an electrically controlled slide rail 21 or a drive method such as screw connecting motor 6, which drives the support 4 to move up and down until the cover cylinder 22 and the base 1 abut to form a relatively closed space. At this time, the waste can be put into the cover cylinder 22. In order to facilitate the feeding, a corresponding feed port can be set on the side of the cover cylinder 22 to avoid the possible obstruction of the extrusion plate 42 to the waste.

[0032] Finally, the output shaft of cylinder 41 extends to push the squeezing disc 42 to squeeze and drain the garbage inside the cover cylinder 22. The water in the garbage is then discharged through the water filter disc 3 and the water receiving cover 5.

[0033] An adjustment assembly is provided between the drying tray 31 and the base 1. When the adjustment assembly is provided, the water filter tray 3 and the drying tray 31 are connected by a rotary seal. The adjustment assembly includes a motor 6 and an air distribution hood 61. The lower end of the drying tray 31 extends downward into the recessed cavity 11. An air groove 62 is opened on the lower side of the drying tray 31, which is connected to the air passage of several exhaust columns 32. The air distribution hood 61 is connected to the lower side of the drying tray 31 by a rotary seal. The air groove 62 is connected to the air distribution hood 61. The air distribution hood 61 is connected to the air passage of the external hot air mechanism. The output shaft of the motor 6 is concentrically connected to the drying tray 31. The air distribution hood 61 and the motor 6 are both fixedly connected to the inner wall of the recessed cavity 11 by a connecting rod.

[0034] The exhaust column 32 has several one-way exhaust ports on its side that are connected to the air groove 62.

[0035] The upper part of the drying tray 31 has a frustum structure with the diameter gradually increasing from top to bottom.

[0036] Furthermore, due to the excessive compactness of the compressed waste, in order to improve the drying effect and efficiency, during the drying process, after the waste has been compressed, the compression disc can be controlled to release part of the compression on the waste. At the same time, the motor 6 is turned on to drive the drying disc to rotate. At this time, the exhaust column set at the upper end of the drying disc will move the waste, making it looser and more conducive to the flow of hot air in the waste. Meanwhile, the air distribution hood is stationary relative to the drying disc. In this way, hot air can still be effectively input and the normal flow of gas can be ensured during the rotation of the drying disc to meet the drying requirements.

[0037] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
