Abstract
Description
Technical Field
[0001] This utility model relates to the field of biochar production technology, specifically a cooling device for biochar produced from plant waste. Background Technology
[0002] Plant waste, also known as biomass waste, mainly includes crop straw, forestry waste, garden waste, and other plant-based waste. These wastes are often considered garbage, but they are actually potential biomass resources. Biochar is a porous carbonaceous solid obtained by high-temperature pyrolysis of biomass under anaerobic or oxygen-deficient conditions. It possesses abundant pore structure, high specific surface area, and various functional groups, making it a promising candidate for applications in adsorption, catalysis, and soil improvement.
[0003] After plant waste is processed into biochar, a cooling device is needed. Chinese utility model patent CN219841679U discloses a biochar cooling device, including a housing, a spiral conveyor, a water tank, a recycled water filter, and a biochar collection box. A biochar conveying box is fixedly installed on the top of the housing, and a drive motor is fixedly installed on the right side of the biochar conveying box. A spiral conveyor is movably installed inside the biochar conveying box. A feeding funnel is fixedly installed on the surface of the biochar conveying box, and a water spray head is fixedly installed on the left side of the feeding funnel. A water-permeable mesh plate is fixedly installed at the bottom of the biochar conveying box. This utility model, through the installation of the housing, spiral conveyor, water spray head, water-permeable mesh plate, recycled water filter, water-permeable mesh plate, biochar collection box, and wastewater collection box, achieves the ability to automatically filter impurities in the recycled water, preventing damage to the water pump or blockage of the water pipes from affecting the cooling process, and filtering the wastewater adhering to the surface of the cooled biochar.
[0004] However, during the use of this utility model, since the biochar is at a high temperature after it is made, simply cooling the surface of the biochar once cannot achieve the best cooling effect. As a result, some temperature will remain on the surface of the biochar, requiring secondary cooling by the staff, which affects production efficiency and cannot meet production needs. Therefore, a cooling device for biochar made from plant waste is proposed to solve the above-mentioned problems. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a cooling device for biochar production from plant waste. It has the advantage of good cooling effect and solves the problem that since the biochar is at a high temperature after production, simply cooling the surface of the biochar once cannot achieve the best cooling effect. As a result, some temperature will remain on the surface of the biochar, requiring secondary cooling by workers, which affects production efficiency and cannot meet production needs.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a cooling device for biochar made from plant waste, comprising a box body and a cooling box fixedly connected to the top of the box body, wherein the box body is provided with a dual cooling mechanism extending into the cooling box to cool the biochar.
[0007] The dual cooling mechanism includes a conveying cylinder fixedly connected inside the cooling box. A water storage tank is slidably connected to the inner bottom wall of the box. Two conveying pumps are fixedly installed inside the box. The ends of the two conveying pumps away from the water storage tank are respectively fixedly connected to a first conveying pipe and a second conveying pipe extending into the cooling box. The end of the first conveying pipe away from the conveying pump is connected to the inside of the conveying cylinder. One end of each of the two conveying pumps is fixedly connected to a connecting pipe extending into the water storage tank.
[0008] Furthermore, a return water pipe is fixedly connected between the cooling tank and the water storage tank, and a liquid level window is fixedly connected to the front of the water storage tank.
[0009] Furthermore, a connecting block is fixedly connected between the inner wall of the cooling box and the conveying cylinder, and the space between the inside of the cooling box and the outside of the conveying cylinder is a cooling chamber.
[0010] Furthermore, a drive motor is fixedly installed on one side of the cooling box, and a drive shaft extending into the inside of the conveying cylinder is fixedly connected to the output shaft of the drive motor. A spiral conveying blade is fixedly installed on the outside of the drive shaft.
[0011] Furthermore, a feed pipe extending to the top of the cooling box is fixedly connected to the top of the conveying cylinder, and a discharge pipe extending into the interior of the box is fixedly connected to the bottom of the conveying cylinder.
[0012] Furthermore, a collection box is slidably connected to the inner bottom wall of the box, and a drain plate extending to its front is slidably connected inside the collection box. The collection box is a hollow, lidless cuboid.
[0013] Furthermore, positioning blocks extending into the collection box are fixedly connected to both the left and right sides of the drain plate, and positioning grooves that match the positioning blocks are provided on the inner wall of the collection box.
[0014] Furthermore, a guide plate is fixedly connected to the inner bottom wall of the collection box, and a drain pipe extending to the outside of the box is fixedly connected to the side of the collection box away from the water storage tank.
[0015] Compared with the prior art, this utility model provides a cooling device for producing biochar from plant waste, which has the following beneficial effects:
[0016] 1. The biochar cooling device made from plant waste can simultaneously deliver clean water from the water storage tank to the first and second delivery pipes by setting two delivery pumps. Then, by setting the first and second delivery pipes, clean water can be delivered to the cooling box and the delivery cylinder respectively, thus achieving both direct and indirect cooling methods and improving the cooling efficiency of biochar.
[0017] 2. The biochar cooling device made from plant waste can collect the cooled biochar by setting up a collection box, and filter out excess water by setting up a drain plate and a drain pipe. This solves the problem that the biochar is at a high temperature after production, and simply cooling the surface of the biochar once is not enough to achieve the best cooling effect. As a result, some heat will remain on the surface of the biochar, requiring secondary cooling by workers, which affects production efficiency and cannot meet production needs.
