TECHNICAL FIELD

[0001] The utility model relates to a kind of waste battery recovery equipment, in particular to a kind of energy-saving heat recovery device. BACKGROUND

[0002] Retired power storage battery is disposed improperly, and there is certain safety hazard, even if battery has not been used, still needs to be recycled and reused, in the process of recycling, waste battery is first advanced pretreatment, then disassembled into different parts, and different parts are handled, recycled or repaired, among them, the recycling and reuse of broken battery scrap is also a part of higher price in recycled battery.

[0003] When traditional battery scrap is handled, generally by microwave tunnel furnace heating, battery fragments are dried by microwave tunnel furnace such relatively closed environment, but battery fragments produce moisture during drying, moisture needs to be discharged, and the existing equipment sets up exhaust fan at the top of furnace body, and enlarges the opening of two ends of feeding and discharging, although it can play a certain role in water vapor discharge, but if the opening of two ends of feeding is enlarged, although moisture can be discharged from the position of feeding, heat will also be discharged, and if the suction of exhaust fan set at the top of furnace body is too large, part of battery scrap will be taken away, if the suction is too small, water vapor is easy to sink to the bottom, and it is difficult to achieve the effect of efficient drying. UTILITARIAN CONTENT

[0004] The utility model provides a kind of energy-saving heat recovery device, not only can efficiently dry battery scrap, but also can leave most heat in furnace body, save fuel more than 30%, can effectively solve the above problems.

[0005] The utility model is realized as follows:

[0006] A kind of energy-saving heat recovery device is set in microwave oven body, the microwave oven body is provided with a conveying belt, the inside of the microwave oven body is provided with microwave heating system, the top of the microwave oven body is provided with a plurality of dehumidification fans, and the heat recovery device further includes:

[0007] Adjustable opening structure, the side of the microwave oven body close to battery scrap feeding is provided with a feeding port, the adjustable opening structure includes fixed part arranged in the inboard of feeding port, the lower end of the fixed part is movably connected with a movable part, the movable part is electrically connected with the power switch of dehumidification fan, the end of the movable part away from the fixed part is provided with shaped end, and the bottom end of the shaped end is attached on the limiting seat of the two ends of conveying belt, when the microwave heating system of the microwave oven body is started, the movable part extends downward and part of shaped end is abutted on conveying belt.

[0008] As a further improvement, the fixed part comprises a concave mounting seat arranged inside the feeding port, and the concave mounting seat is internally provided with a plurality of lumen.

[0009] As a further improvement, the movable part comprises a movable element arranged in the lumen, and the movable element is externally covered with a sealing surface, and the upper edge of the sealing surface is glued to the inner wall of the concave mounting seat.

[0010] As a further improvement, the movable element is a non-powered bellows, or the movable element is a gas cylinder, and the power source of the gas cylinder is electrically connected with the power switch of the dehumidification fan.

[0011] As a further improvement, the shaped end comprises a sealing strip arranged at the bottom of the sealing surface, and the two ends of the sealing strip are internally provided with two fixed anchor points, and the two fixed anchor points are movably arranged on the limiting seats at the two ends of the conveying belt, and the sealing strip is pulled down or lifted to change the height between the sealing strip and the conveying belt.

[0012] The microwave tunnel furnace of the present application has the following advantages:

[0013] In the existing microwave tunnel furnace, the size of the inlet of the tunnel furnace is always the same, and the inlet of the tunnel furnace cannot be adjusted regardless of the size of the individual feeding or the total amount of feeding. If the opening of the tunnel furnace is too large, the heat will be easily lost, and if the opening of the tunnel furnace is too small, the power of the dehumidification fan needs to be increased, which will easily suck away part of the battery debris. Therefore, the adjustable opening structure is arranged, and after the fixed part of the fixed region is arranged, the movable part which can be adjusted is also arranged. The coverage area of the movable part can be adjusted according to the power of the dehumidification fan. When the power of the dehumidification fan gradually increases, it proves that the humidity in the furnace body is too large at this time, and the movable part acts upward to expand the feeding port of the microwave furnace body, so that the microwave furnace body has a certain dehumidification function at this time. When the power of the dehumidification fan is constant or gradually decreases, it indicates that the current batch of battery debris is relatively dry, so the movable part can act downward to reduce the feeding port of the microwave furnace body, so that most of the heat is retained in the furnace body, thereby achieving the effect of reducing energy consumption.

[0014] The adjustment distance of the whole movable part is actually limited. If the adjustment of the movable part is difficult to have stability relative to the height of the existing feeding port, the fixed part of the present application is arranged as an extension of the whole movable part, and provides a certain installation space for the whole movable part. At the same time, the positions of the movable part before and after adjustment are both in the appropriate interval, and the interval after adjustment is more suitable for dehumidification and heat preservation.

[0015] When the movable part is active, it needs to be face shield, not single-axis or single-column shield, therefore, the movable part of the utility model is an integral face shield after unfolding, the passageway between the inside and outside is shielded through the face shield, so as to control the size of the air inlet face, and the power of the face shield can come from the manually set movable part or the electrically set cylinder, which can be customized according to requirements, and if the movable part is set in the electric mode, the movable part and the power switch of the dehumidification fan need to be electrically connected, so as to achieve the effect that the dehumidification fan is strong, the movable part is weak, the dehumidification fan is weak, and the movable part is strong.

[0016] In fact, the entire forming end contacts the limiting seat at both ends of the conveying belt, so the forming end must have a certain curvature, therefore, the utility model is provided with the forming end, the bottom of the forming end is provided with the arc-shaped sealing belt, and in order to make the both ends of the arc-shaped sealing belt have stability, the fixed anchor points are further arranged on the bottom of the both sides of the arc-shaped sealing belt, so that the both sides of the sealing belt can be stabilized, and even under the suction of the negative pressure wind power, the phenomenon of inward collapse does not occur.
