Description

Technical Field

[0001] This utility model relates to the technical field of manure treatment, and in particular to a deodorizing device for treating manure in livestock farms. Background Technology

[0002] Livestock manure treatment is a crucial aspect of ensuring sustainable environmental development. Improper treatment of livestock manure can have serious environmental impacts. Nutrients such as nitrogen and phosphorus in manure, if discharged into water bodies, can easily lead to eutrophication, affecting the survival of aquatic organisms. Furthermore, harmful substances such as heavy metals and pathogens in manure can enter the human body through soil and the food chain, affecting health. Therefore, effective manure treatment technology is key to protecting the environment and safeguarding human health.

[0003] The existing Chinese utility model patent with application number CN202320809533.9 relates to a manure treatment device for livestock farms, including a base, shell, feed pipe, exhaust pipe, valve, servo motor, drive gear, transmission gear, stirring gear and storage battery, which can improve the working efficiency of the device and avoid blockage of manure discharge.

[0004] However, the above-mentioned device does not have the ability to add various additives in a quantitative manner in actual use, and it does not have the ability to screen out impurities in sewage. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a livestock farm manure treatment and deodorization device that uses a screening device to remove impurities and weeds from manure, a driving device to provide power to the screening device to accelerate the screening rate, a conveying device to transport the screened manure, an aeration device to aerate the manure, and a liquid addition device to quantitatively add active biological treatment agent to the conveying device. This improves the practicality of the device and reduces the labor intensity of operators.

[0006] This utility model discloses a livestock farm manure treatment and deodorization device, comprising a screening device, a driving device, a conveying device, an aeration device, and a liquid addition device. The driving device is installed on the screening device, the conveying device is connected to the screening device, the aeration device is installed on the conveying device, and the liquid addition device is installed on the conveying device. The screening device removes impurities and weeds from the manure, the driving device provides power to the screening device to accelerate the screening rate, the conveying device transports the screened manure, the aeration device aerates the manure, and the liquid addition device quantitatively adds active biological treatment agent to the conveying device. This improves the practicality of the device and reduces the labor intensity of operators.

[0007] Preferably, the screening device includes a frame, a rotating shaft, a screening rack, a screening plate, and nozzles. The rear of the screening rack is connected to the inside of the frame via the rotating shaft. A screening plate is installed at the bottom of the screening rack, and multiple sets of nozzles are installed in the upper part of the frame. The screening plate on the screening rack removes impurities from the manure, reducing the impact of impurities on subsequent processing. The rotating shaft allows the front of the screening rack to rotate around the shaft, thereby changing the elevation and tilt angle of the screening rack, facilitating the screening of manure and the discharge of impurities accumulated on the screening rack. The multiple sets of nozzles in the upper part of the frame provide water to the manure, enabling the equipment to screen dried manure and improving the practicality of the device.

[0008] Preferably, the driving device includes a spring, an electromagnet, and an iron base. The front of the bottom end of the frame is connected to the front of the lower end of the screening frame via a set of springs on the left and right sides respectively. An electromagnet is installed at an angle on the front of the bottom end of the frame, and an iron base is installed on the front of the lower end of the screening frame. By intermittently opening and closing the electromagnet, a magnetic force is provided to the iron base, thereby driving the front of the screening frame to vibrate up and down, so that the manure can be spread evenly inside the screening frame, improving the screening efficiency of the screening device. The spring provides auxiliary support to the front of the screening frame, improving the practicality of the device.

[0009] Preferably, it also includes a baffle bar, which is provided at the front of the bottom end of the screening frame; the baffle bar at the front of the bottom end of the screening frame intercepts the manure entering the screening frame, preventing the manure from flowing out directly from the front end of the screening frame, thus improving the practicality of the device.

[0010] Preferably, the conveying device includes a discharge hopper, a conveying pipe, a geared motor, spiral blades, and a reaction chamber. The discharge hopper is located on the bottom surface of the frame, and the conveying pipe is installed below the discharge hopper. Spiral blades are installed inside the conveying pipe, and the geared motor is installed on the right end of the conveying pipe.

The left end of the spiral blades is located on the left side of the spiral blades, and the reaction chamber is located above the spiral blades. The output end of the spiral blades is connected to the interior of the reaction chamber. The screened manure is collected by the discharge hopper and conveyed into the conveying pipe. Then, the geared motor is turned on to transmit power to the spiral blades, which drive the spiral blades to rotate. The rotating spiral blades convey the manure into the reaction chamber for subsequent biological reactions, converting the organic matter in the manure into inorganic matter and reducing the odor of the manure.

[0011] Preferably, the aeration device includes aeration pipes, an aerator, filter plates, and a drain outlet. Multiple sets of aeration pipes are installed in the lower part of the reaction chamber, and an aerator is installed on the outer surface of the reaction chamber.

Multiple sets of filter plates are installed inside the reaction chamber, and a drain outlet is provided in the upper part of the reaction chamber. Gas is introduced into the reaction chamber through the multiple sets of aeration pipes by the aerator, and large-diameter pollutants in the reaction chamber are intercepted by the multiple sets of filter plates. Wastewater is discharged through the drain outlet, which improves the practicality of the device.

[0012] Preferably, the liquid addition device includes a storage tank, a metering tank, an electric cylinder, a first solenoid valve, a delivery pipe, and a second solenoid valve. The storage tank is mounted on the upper surface of the reaction chamber via a bracket. The metering tank is also mounted on the upper surface of the reaction chamber. An electric cylinder is mounted on the left side of the metering tank, with its moving end extending into the metering tank. A piston is connected to the moving end of the electric cylinder. The first solenoid valve is mounted on the lower surface of the storage tank, and its output end is connected to the right side of the metering tank. A delivery pipe is connected to the right side of the metering tank, and a second solenoid valve is mounted on the output end of the delivery pipe. Opening the first solenoid valve releases the active additive from the storage tank into the metering tank. By controlling the extension of the electric cylinder, the piston inside the metering tank moves, controlling the effective space within the metering tank and the amount of additive added at one time. Then, closing the first solenoid valve, opening the second solenoid valve, and controlling the extension of the electric cylinder pushes the additive from the metering tank into the reaction chamber for reaction, thus improving the practicality of the device.
