Description

Technical Field

[0001] This utility model relates to the field of heating devices, and more particularly to a heating device for garbage pits. Background Technology

[0002] Waste-to-energy incineration can effectively recycle, reduce, and harmlessly dispose of urban household waste. It not only makes full use of the calorific value of waste, but also treats the harmful components produced by combustion through a flue gas treatment system, thereby reducing environmental pollution.

[0003] In existing technologies, such as the Chinese patent application CN205939161U entitled "A Heating Device for a Waste Storage Pit," several heating units are arranged in parallel around the bottom of the waste storage pit. The inlet of each heating unit is connected via a main inlet pipe, and the return outlet of each heating unit is connected via a main return pipe. Each heating unit includes a shell and a hot water coil. The inlet of the hot water coil is equipped with an inlet shut-off valve, and the return outlet of the hot water coil is equipped with a return shut-off valve. Both the inlet and return shut-off valves are located outside the waste storage pit. The outer shell of the heating unit, on the storage side, directly contacts the air or waste inside the pit. This invention offers good energy-saving performance, effectively increasing the temperature of the waste storage pit, promoting waste fermentation and dehydration, increasing the calorific value of the waste entering the incinerator, and making combustion in the incinerator more stable. Simultaneously, the increased temperature inside the waste storage pit helps to improve the primary air inlet temperature and the thermal efficiency of the incinerator.

[0004] In existing technologies for heating garbage pits, the heating water flow is difficult to reach the gaps between the garbage pits due to the heat conduction of the garbage through the water flow. This makes it difficult for the heating water flow to fully heat the accumulated garbage, resulting in low garbage heating efficiency.

[0005] Therefore, it is necessary to provide a heating device for the landfill to solve the above-mentioned technical problems. Utility Model Content

[0006] To solve the above-mentioned technical problems, the present invention provides a garbage pit heating device, including a fixed platform, a processing tank inside the fixed platform, a sealing cover fixedly fitted on the top of the processing tank, a temperature sensor installed on the top of the inner cavity of the processing tank, a fan fixedly installed on the top of the fixed platform, a heating box fixedly connected to the top of the fixed platform, a steam heat exchanger fixedly installed inside the heating box, an air inlet pipe fixedly fitted inside the processing tank, an exhaust pipe fixedly fitted on the top of the side of the processing tank, a protective net fixedly fitted at one end of the air inlet pipe, a controller fixedly installed on the top of the fixed platform, a filter mechanism installed at one end of the exhaust pipe, a heat insulation cover fixedly fitted inside the heating box, heat-conducting fins fixedly fitted outside the steam heat exchanger, and a fixing mechanism installed at the bottom of the fan.

[0007] Preferably, one end of the exhaust pipe is fixedly sleeved on the side of the fan, and the exhaust pipe is made of stainless steel.

[0014] Compared with related technologies, the garbage pit heating device provided by this utility model has the following beneficial effects:

[0015] This utility model provides a garbage pit heating device. By setting an exhaust pipe, when the garbage is being heated, the steam heat exchanger is started, which heats the air inside the heating box. At this time, the fan is started, which drives the air inside the heating box to enter the bottom of the inner cavity of the processing tank through the air inlet pipe. This allows the high-temperature air to heat the garbage inside the processing tank. The heated air then flows through the gaps in the garbage to the top of the inner cavity of the processing tank and then flows back into the interior of the heating box through the exhaust pipe. This increases the contact area between the hot air and the garbage, thus improving the heating efficiency of the garbage.

[0016] By setting up a controller, when the garbage is heated, the temperature sensor and controller are activated, allowing the temperature sensor to detect the temperature inside the processing tank and transmit the detection result to the controller. This enables the controller to control the steam heat exchanger to heat the cold air entering the heating box to about 90 degrees Celsius, thus achieving the heating effect of the circulating air in the garbage pit. This keeps the temperature inside the garbage pit at about 20 degrees Celsius, thereby achieving the automatic heating effect of the garbage. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments. Figure 1 A schematic diagram of a preferred embodiment of the garbage pit heating device provided by this utility model; Figure 2 for Figure 1 The front view of the garbage pit heating device shown; Figure 3 for Figure 1 A front view of the heat-conducting fins in the heating device for the garbage pit shown; Figure 4 for Figure 1 The diagram shows the electrical connection of the controller in the garbage pit heating device. The garbage pit heating device includes a fixed platform 1, a processing tank 2 inside the fixed platform 1, a sealing cover 3 fixedly fitted on the top of the processing tank 2, a temperature sensor 4 fixedly fitted on the top of the inner cavity of the processing tank 2, a fan 5 fixedly installed on the top of the fixed platform 1, a heating box 6 fixedly connected to the top of the fixed platform 1, a steam heat exchanger 7 fixedly installed inside the heating box 6, an air inlet pipe 8 fixedly fitted inside the processing tank 2, an exhaust pipe 9 fixedly fitted on the top of the side of the processing tank 2, a protective net 10 fixedly fitted at one end of the air inlet pipe 8, a controller 11 fixedly installed on the top of the fixed platform 1, a filter mechanism 12 installed at one end of the exhaust pipe 9, a heat insulation cover 13 fixedly fitted inside the heating box 6, heat-conducting fins 14 fixedly fitted outside the steam heat exchanger 7, and a fixing mechanism 15 at the bottom of the fan 5.

[0023] One end of the exhaust pipe 9 is fixedly sleeved on the side of the blower 5. The exhaust pipe 9 is made of stainless steel. By setting the exhaust pipe 9, when the garbage is heated, the steam heat exchanger 7 is started, so that the steam heat exchanger 7 can heat the air inside the heating box 6. At this time, the blower 5 is started, so that the blower 5 can drive the air inside the heating box 6 into the bottom of the inner cavity of the processing tank 2 through the air inlet pipe 8. This allows the high-temperature air to heat the garbage inside the processing tank 2. The heated air can then flow through the gaps in the garbage to the top of the inner cavity of the processing tank 2 and then flow back into the interior of the heating box 6 through the exhaust pipe 9. This increases the contact area between the hot air and the garbage, thus improving the heating efficiency of the garbage.

[0024] The protective net 10 is made of stainless steel, and there are two protective nets 10. By setting the protective net 10, when the processing tank 2 is ventilated and heated, the protective net 10 can block and limit the garbage inside the processing tank 2, so as to avoid the garbage flowing back into the air inlet pipe 8 and causing blockage, thereby improving the smoothness of the air inlet pipe 8.

[0025] The input terminal of the controller 11 is connected to the output terminal of the temperature sensor 4, and the output terminal of the controller 11 is electrically connected to the input terminals of the steam heat exchanger 7 and the fan 5 respectively. By setting the controller 11, when the garbage is heated, the temperature sensor 4 and the controller 11 are activated, so that the temperature sensor 4 can detect the internal temperature of the processing tank 2 and transmit the detection result to the controller 11. This allows the controller 11 to control the steam heat exchanger 7 to heat the cold air entering the heating box 6 to 90 degrees, which achieves the heating effect of the circulating air in the garbage pit, so that the internal temperature of the garbage pit is maintained at about 20 degrees, thus achieving the automatic heating effect of garbage.

[0026] The filtration mechanism 12 includes a closed sleeve 121, which is fixedly fitted to one end of the exhaust pipe 9. A filter element 122 is movably fitted inside the closed sleeve 121, and a closed cover 123 is threaded onto the side of the closed sleeve 121. By setting up the filtration mechanism 12, when high-temperature air is recovered inside the treatment tank 2, the filter element 122 can filter the air inside the closed sleeve 121, so that dust in the air can be blocked and retained inside the filter element 122, thereby achieving the filtration effect of the recovered air. This avoids the problem of dust flowing back into the heating box 6 with the air, causing the heating box 6 to become dirty, thereby improving the cleanliness of the heating box 6.

[0027] The heat insulation cover 13 is compatible with the heating box 6, and the heat insulation cover 13 is made of fiberglass material. By setting the heat insulation cover 13, when the steam heat exchanger 7 heats the air inside the heating box 6, the heat insulation cover 13 can block the heat inside the heating box 6, thereby avoiding the problem of rapid heat loss inside the heating box 6 and improving the heat preservation effect inside the heating box 6.

[0028] The heat-conducting fins 14 are made of aluminum, and there are several heat-conducting fins 14. By setting the heat-conducting fins 14, when the steam heat exchanger 7 heats the air inside the heating box 6, the heat inside the steam heat exchanger 7 can be quickly transferred to the heat-conducting fins 14, thereby increasing the contact area between the steam heat exchanger 7 and the air, which increases the heating speed of the air inside the heating box 6, and thus increases the heating efficiency of the air.

[0029] The fixing mechanism 15 includes a support frame 151, which is fixedly connected to the bottom of the fan 5. The bottom of the support frame 151 is threaded with a bolt 152. By setting the fixing mechanism 15, when the fan 5 is installed and fixed, the bolt 152 is rotated so that the bolt 152 can fix the support frame 151 to the top of the fixing platform 1, thereby achieving the installation and fixing effect of the fan 5, and thus bringing convenience to the installation and fixing of the heating device.

[0030] The working principle of the garbage pit heating device provided by this utility model is as follows:

[0031] Step 1: First, when heating the waste, start the steam heat exchanger 7 to heat the air inside the heating chamber 6. At the same time, start the blower 5, which drives the air inside the heating chamber 6 through the air inlet pipe 8 into the bottom of the processing tank 2. This allows the higher-temperature air to heat the waste inside the processing tank 2. The heated air then flows through the gaps in the waste to the top of the processing tank 2 and then returns to the interior of the heating chamber 6 through the exhaust pipe 9, thus increasing the contact area between the hot air and the waste, thereby improving the heating efficiency. When the processing tank 2 is being heated, the protective net 10 blocks and limits the waste inside the processing tank 2, preventing waste from flowing back into the air inlet pipe 8 and causing blockage, thus improving the flow rate of the air inlet pipe 8. In terms of smooth operation, when the waste is heated, the temperature sensor 4 and the controller 11 are activated, so that the temperature sensor 4 can detect the internal temperature of the processing tank 2 and transmit the detection result to the controller 11. When the internal temperature of the processing tank 2 is low, the controller 11 can control the power of the steam heat exchanger 7 and the fan 5 to increase, thereby accelerating the heating speed of the waste inside the processing tank 2, thus achieving the effect of automatic waste heating. When the high-temperature air inside the processing tank 2 is recovered, the filter element 122 can filter the air inside the closed sleeve 121, so that the dust in the air can be blocked and trapped inside the filter element 122, thereby achieving the effect of air filtration and preventing dust from flowing back into the heating box 6 with the air, causing the heating box 6 to become dirty, thus improving the cleanliness of the heating box 6.

[0032] Step 2: When the steam heat exchanger 7 heats the air inside the heating box 6, the heat insulation cover 13 blocks the heat inside the heating box 6, thus preventing the rapid loss of heat inside the heating box 6 and improving the heat preservation effect inside the heating box 6. When the steam heat exchanger 7 heats the air inside the heating box 6, the heat inside the steam heat exchanger 7 is quickly transferred to the heat-conducting fins 14, thereby increasing the contact area between the steam heat exchanger 7 and the air, which increases the heating speed of the air inside the heating box 6 and improves the heating efficiency of the air. When the fan 5 is installed and fixed, the bolt 152 is rotated so that the bolt 152 can fix the support frame 151 to the top of the fixed platform 1, thus achieving the installation and fixing effect of the fan 5, which brings convenience to the installation and fixing of the heating device.

[0033] Compared with related technologies, the garbage pit heating device provided by this utility model has the following beneficial effects:

[0034] By setting up an exhaust pipe 9, when the waste is being heated, the steam heat exchanger 7 is activated, allowing the steam heat exchanger 7 to heat the air inside the heating chamber 6. At this time, the blower 5 is activated, allowing the blower 5 to drive the air inside the heating chamber 6 through the air inlet pipe 8 into the bottom of the inner cavity of the processing tank 2. This allows the high-temperature air to heat the waste inside the processing tank 2, so that the heated air can flow through the gaps in the waste to the top of the inner cavity of the processing tank 2 and then flow back into the interior of the heating chamber 6 through the exhaust pipe 9. This increases the contact area between the hot air and the waste, thereby improving the heating efficiency of the waste.
