Description

Technical Field

[0001] This utility model relates to the technical field of livestock and poultry breeding, and in particular to a dehumidifier for livestock and poultry houses. Background Technology

[0002] In livestock and poultry houses, the evaporation of moisture from animal manure can lead to excessively high humidity, necessitating regular dehumidification. Existing technology includes a utility model patent with patent application number 202022702661.2, which discloses a dehumidifier with air purification function. This dehumidifier mainly consists of a body, an air inlet, and a filter. When dehumidifying the air, it draws in air through the air inlet, filters it through the filter, and then dehumidifies it before expelling it through the exhaust vent. However, this dehumidifier has the following problems: with increasing usage time, more and more solid impurities accumulate on the filter, and it lacks a device for cleaning these impurities, requiring manual cleaning by staff, which is inconvenient. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a dehumidifier for livestock and poultry houses that can assist workers in cleaning the filter screen on the ventilation plate, reducing labor intensity, and is easy to use and highly practical.

[0004] This utility model discloses a dehumidifying fan for livestock and poultry houses, comprising a ground, a support frame, and a condenser. The condenser is fixedly installed on the ground via the support frame. It also includes a support frame, a filter cylinder, an air inlet pipe, a permeable plate, a cleaning mechanism, a conveying mechanism, and an exhaust mechanism. The filter cylinder is installed on the ground via the support frame and has a chamber inside. The output end of the air inlet pipe is connected to the lower part of the filter cylinder chamber, and a valve is installed on the air inlet pipe. The permeable plate is installed on the upper part of the filter cylinder chamber, and a filter screen is installed on the permeable plate at its lower end. The permeable plate is located above the air inlet pipe. The cleaning mechanism is installed on the filter cylinder and is used to clean the permeable plate. The input and output ends of the conveying mechanism are connected to the filter cylinder and the condenser, respectively. The condenser is equipped with an exhaust mechanism for exhausting air. The condenser is a shell-and-tube type condenser, connected to an external refrigeration system. The cooling medium flows through the tubes, requiring dry air. The system features a conveyor system; the air inlet pipe connects to the exhaust pipe of the livestock and poultry house, and the exhaust mechanism connects to the air inlet pipe. When air drying is required in the livestock and poultry house, the conveyor mechanism is opened, allowing air to enter the chamber of the filter cartridge through the air inlet pipe. The air then passes through the filter screen on the permeable plate and enters the upper part of the filter cartridge chamber. The filter screen removes solid impurities from the air. The filtered air then enters the condenser through the conveyor mechanism, where it is cooled, causing moisture to condense and fall, reducing humidity. The air then enters the air inlet pipe of the livestock and poultry house through the exhaust mechanism, and the dried air then enters the livestock and poultry house. When cleaning the filter screen on the permeable plate is required, the cleaning mechanism is opened, and the filter screen on the permeable plate is cleaned using the cleaning mechanism. This system assists workers in cleaning the filter screen on the permeable plate, reducing labor intensity, and is convenient and highly practical.

[0005] Preferably, it also includes a water tank, which is installed on the ground. The water tank is equipped with a water inlet pipe and a valve. A drain pipe is installed at the bottom of the condenser and is connected to the water tank. The drain pipe is also equipped with a valve. The drain pipe is connected to the bottom of the condenser shell. When it is necessary to drain the condensed water in the condenser, the valve on the drain pipe is opened, allowing the condensed water in the condenser to be discharged into the water tank for collection. This facilitates water collection.

[0006] Preferably, the cleaning mechanism includes a delivery pump, a delivery pipe, and a nozzle. The input end of the delivery pump is connected to a water tank, and the output end of the delivery pump is connected to the nozzle through the delivery pipe. The nozzle is located at the upper part of the filter cartridge chamber and above the air permeable plate. A drain pipe connected to the chamber is provided at the lower part of the filter cartridge, and a valve is provided on the drain pipe. When it is necessary to clean the filter screen on the air permeable plate, the valve on the air inlet pipe is closed, and then the delivery pump is turned on, so that the water in the water tank enters the nozzle through the delivery pump and the delivery pipe in sequence. Then the water is sprayed onto the air permeable plate through the nozzle, and the water washes the filter screen at the lower end of the air permeable plate, washing off the solid impurities attached to the filter screen. The washed water falls to the lower part of the filter cartridge chamber. Then the valve on the drain pipe is opened to discharge and collect the washed water. This facilitates the cleaning of the air permeable plate.

[0007] Preferably, the exhaust mechanism includes an exhaust pipe A, an exhaust pipe B, and a heating mechanism. Both exhaust pipe A and exhaust pipe B are connected to a condenser, and both exhaust pipe A and exhaust pipe B are equipped with valves. The output end of exhaust pipe B is connected to the heating mechanism. The output end of exhaust pipe A is directly connected to the air intake pipe of the poultry and livestock house, and the heating mechanism is also connected to the air intake pipe of the poultry and livestock house. In the hot summer, the valve on exhaust pipe B is closed, and the valve on exhaust pipe A is opened, allowing the air to be condensed and dried in the condenser and then directly enter the air intake pipe of the poultry and livestock house through exhaust pipe A, thus allowing cool air to enter the poultry and livestock house. In the cold winter, the valve on exhaust pipe A is closed, and the valve on exhaust pipe B is opened, allowing the air cooled in the condenser to enter the heating mechanism through exhaust pipe B for heating, and then the heated air enters the poultry and livestock house through the air intake pipe, preventing the temperature inside the poultry and livestock house from becoming too low.

[0008] Preferably, the heating mechanism includes a cylinder and an exhaust pipe. The cylinder has a cavity, and multiple electric heating grids are installed inside the cavity. The output end of the exhaust pipe B is connected to the left side of the cavity, and the input end of the exhaust pipe is connected to the right side of the cavity. The output end of the exhaust pipe is connected to the air inlet pipe of the poultry and livestock house. When it is necessary to heat the dried air, the valve on the exhaust pipe B is opened, allowing the air in the condenser to enter the cylinder through the exhaust pipe B. The air is heated as it passes through the electric heating grids, and the heated air enters the poultry and livestock house through the exhaust pipe, which facilitates the heating of the air and ensures the environment for the poultry and livestock.

[0009] Preferably, the conveying mechanism includes an induced draft fan and an air supply pipe. The input end of the induced draft fan is connected to the upper part of the filter cartridge chamber, and the output end of the induced draft fan is connected to the condenser through the air supply pipe. By turning on the induced draft fan, the air in the filter cartridge can enter the condenser through the induced draft fan and the air supply pipe for condensation and drying, which facilitates the drying of the air.

[0010] Preferably, the filter also includes a lifting mechanism, a sleeve, a rotating shaft, an indexing plate, and a brush. The sleeve is rotatably installed at the lower part of the filter cylinder and has a sliding groove.

The brush is fixedly installed at the upper end of the rotating shaft. The indexing plate is installed on the lifting mechanism, which is used to raise and lower the indexing plate, which is located below the filter cylinder. When the filter screen at the lower end of the air vent plate is rinsed by the nozzle, the lifting mechanism raises the indexing plate and the rotating shaft, thereby raising the brush to contact the filter screen at the lower end of the air vent plate. Then, the indexing plate is opened, causing the rotating shaft to drive the brush to rotate. During the rotation, the brush washes the filter screen, removing the impurities attached to the filter screen, thus improving the efficiency of filter screen cleaning.

[0011] Preferably, the lifting mechanism includes a hydraulic cylinder, a push rod, a sliding rod, and a lifting plate. The hydraulic cylinder is installed on the ground, and a push rod is provided at the power output end of the hydraulic cylinder. The sliding rod is fixedly installed on the ground, and the lifting plate is fixedly installed on the upper end of the push rod.

A cleaning mechanism is installed on the filter cartridge 5 and is used to clean the permeable plate 7. The input and output ends of the conveying mechanism are connected to the filter cartridge 5 and the condenser 3, respectively. An exhaust mechanism is provided on the condenser 3, which has the function of exhausting air. The condenser 3 is a shell-and-tube condenser, connected to an external refrigeration system.

The air inlet pipe 6 is connected to the exhaust pipe of the livestock and poultry house, and the exhaust mechanism is connected to the air inlet pipe of the livestock and poultry house. The system is interconnected. When air drying is required in the livestock and poultry house, the conveying mechanism is opened, allowing air from the livestock and poultry house to enter the chamber of the filter cylinder 5 through the air inlet pipe 6. After passing through the filter screen on the permeable plate 7, the air enters the upper part of the chamber of the filter cylinder 5. The filter screen filters out solid impurities in the air. The filtered air then enters the condenser 3 through the conveying mechanism. The air is cooled in the condenser 3, causing the moisture in the air to condense into liquid and fall, reducing the humidity of the air. Afterward, the air enters the air inlet pipe of the livestock and poultry house through the exhaust mechanism. The dried air then enters the livestock and poultry house. When the filter screen on the permeable plate 7 needs to be cleaned, the cleaning mechanism is opened, and the filter screen on the permeable plate 7 can be cleaned through the cleaning mechanism.

When it is necessary to clean the filter screen on the air permeable plate 7, the valve on the air inlet pipe 6 is closed, and then the delivery pump 10 is turned on, so that the water in the water tank 9 enters the nozzle 12 through the delivery pump 10 and the delivery pipe 11 in sequence. Then the water is sprayed onto the air permeable plate 7 through the nozzle 12, and the filter screen at the lower end of the air permeable plate 7 is washed off by the water, and the washed water falls into the lower part of the chamber of the filter cartridge 5. Then the valve on the drain pipe is opened to discharge the washed water and collect it. This facilitates the cleaning of the air permeable plate 7.
