Description

Technical Field

[0001] The present invention relates to the technical field of aquaculture, and particularly relates to a throwing barrel applying material-gas separation. Background Art

[0002] During the process of aquaculture, it is necessary to feed fish. Currently, the main feeding method is to use a pneumatic conveying system to transport feed to a feed barrel, and the feed barrel discharges the feed onto the water surface of the pool in the aquaculture workshop. There are powders and gases during the transportation of the feed. The dust is directly discharged into the aquaculture workshop, which will cause the feed to mildew, affect the health of aquatic products, and moreover, the existing technology cannot control the falling amount of the feed barrel. Summary of the Invention

[0003] The purpose of the present invention is to provide a throwing barrel applying material-gas separation, aiming to solve the technical problems that the feed is prone to mildew and the falling amount of the feed barrel cannot be controlled in the existing technology.

[0004] To solve the above technical problems, the technical solution of the present invention is:

[0005] A throwing barrel applying material-gas separation includes a barrel body, a feeding pipe, a discharging pipe, an exhaust pipe, and a material conveying pipe. The bottom of the barrel body is arranged in a conical shape. The feeding end of the feeding pipe is installed on the discharging end of the material conveying pipe. The discharging end of the feeding pipe is connected to the feeding end of the discharging pipe. There is an included angle between the discharging pipe and the material conveying pipe. The intake end of the exhaust pipe extends into the barrel body. A feeding pipe is provided at the lower end of the barrel body, and a feeder is installed on the feeding pipe. The feeder includes a feeding housing. The upper end of the feeding housing is fixedly connected with a feeding pipe communicating with the feeding pipe. The lower end of the feeding housing is fixedly connected with a falling pipe located directly below the feeding pipe. A rotating shaft driven by a driving mechanism is installed in the feeding housing. A dial block is installed on the rotating shaft. A plurality of evenly circumferentially distributed dial plates are provided on the dial block, and the outer ends of the dial plates extend to abut against the inner wall of the feeding housing.

[0006] With the above structure, the material conveying pipe transports the feed into the feeding pipe, and then enters the barrel body through the discharging pipe. Since there is an included angle between the discharging pipe and the material conveying pipe, a spiral air flow is formed in the barrel body. Due to the action of gravity, the feed falls to the bottom of the barrel body. Tiny solid particles are captured on the barrel wall, and the remaining powder and the separated gas are discharged from the barrel body through the exhaust pipe, realizing material-gas separation. The feed is not prone to mildew. The feed enters the feeding housing through the feeding pipe. The driving mechanism rotates to drive the dial plate to rotate, and the feed is thrown out from the falling pipe. During use, the falling amount of the feed can be controlled by controlling the rotation speed of the driving mechanism, and after the driving mechanism stops operating, the dial plate can close the feeding housing to stop the falling of the material.

[0007] Preferably, a connection housing is fixedly connected to one side of the feed pipe. The connection housing includes a cylindrical barrel communicating with the feed pipe. A conical barrel is fixedly connected to the outer end of the cylindrical barrel. The caliber of the conical barrel is tapered outward. A connecting pipe is fixedly connected to the outer end of the conical barrel. A spraying housing adapted to the conical barrel is slidably installed in the connection housing. A plurality of first spray nozzles are opened at the bottom of the spraying housing. An elastic mechanism for driving the spraying housing to be inserted into the conical barrel is installed on the connection housing. A water inlet pipe is installed at the outer end of the connecting pipe. The lower end of the water inlet pipe extends underwater. A water pump is installed on the water inlet pipe. After the feed in the barrel is emptied, the water pump transports water through the water inlet pipe into the spraying housing. The spraying housing moves into the connection housing under the impact of water, leaving the position of the conical barrel. The conical barrel no longer closes the first spray nozzles of the spraying housing, and water sprays out from the first spray nozzles to wash the feed residues on the feeding housing and the baffle. At the same time, the driving mechanism drives the baffle to rotate to discharge the washed wastewater. After the washing is completed, the baffle continues to rotate for a period of time to throw out the water on the baffle. The spraying housing is reset under the action of the elastic mechanism, and the conical barrel closes the spraying housing, and the spraying housing does not affect the feed from falling into the feeding housing. By washing the feed residues on the feeding housing and the baffle, the residual feed residues in the feeding housing are prevented from mildewing.

[0008] Preferably, a filtering housing is installed at the lower end of the water inlet pipe. A plurality of filtering holes are opened at the bottom and side of the filtering housing. The setting of the filtering housing avoids feed and sundries from entering the water inlet pipe and affecting the washing of the feeding housing.

[0009] Preferably, a cylindrical housing adapted to the cylindrical barrel is connected to the inner end of the spraying housing. A plurality of second spray nozzles are opened at the bottom of the cylindrical housing. The setting of the cylindrical housing and the second spray nozzles can increase the washing range and improve the washing efficiency.

[0010] Preferably, the outer end of the spraying housing is closed and the inner end is open. An inlet water plate is fixedly connected to the inner end of the spraying housing. The inlet water plate includes a first mounting plate at the center. A plurality of first connecting plates connecting the spraying housing are fixedly connected to the outer edge of the first mounting plate. A fixing plate is fixedly connected to the connecting pipe. The fixing plate includes a second mounting plate at the center. A plurality of second connecting plates connecting the connecting pipe are fixedly connected to the outer edge of the second mounting plate. A sliding rod is fixedly connected to the outer plate surface of the first mounting plate. A sliding hole adapted to the sliding rod is opened on the second mounting plate. The outer end of the sliding rod passes through the sliding hole, and a limiting plate is fixedly connected to the outer end of the sliding rod. The elastic mechanism is a compression spring sleeved on the sliding rod section between the limiting plate and the second mounting plate. The first mounting plate and the second mounting plate adopt the above structure, which can reduce the interference with the water flow, and the water flow can enter the spraying housing. The cooperation of the sliding rod and the sliding hole guides the movement of the spraying housing, and the setting of the limiting plate can limit the compression spring.

[0011] Preferably, a groove extending along the length direction is formed on the sliding rod, and a protrusion adapted to the groove is provided on the sliding hole. The cooperation of the protrusion and the groove can prevent the rotation of the spraying housing and avoid the change of the position of the first spray port.

[0012] Preferably, a filter cylinder is fixedly connected to the top of the cylinder body. A filter net is installed at the lower end of the filter cylinder, and the exhaust pipe communicates with the cylinder wall of the filter cylinder. The filter net can block the granular feed carried in the gas and avoid the waste of feed.

[0013] Preferably, the discharge pipe is an L-shaped pipe. The vertical part of the discharge pipe extends out of the cylinder body and is connected to the feeding pipe. The exhaust pipe is a horizontal pipe. The air outlet end of the exhaust pipe extends out of the cylinder body and is connected to the return pipe through a pipeline. Adopting the above structure for the discharge pipe can facilitate the connection between the discharge pipe and the feeding pipe. Adopting the above structure for the exhaust pipe can facilitate the discharge of gas.

[0014] Preferably, the cylinder body includes a lower shell and an end cover. The bottom of the lower shell is tapered. The discharge pipe, the filter cylinder, the exhaust pipe and the end cover are integrally cast. Integrally casting the discharge pipe, the filter cylinder, the exhaust pipe and the end cover can improve the stability of each pipeline and the end cover and avoid the deformation of the pipeline.

[0015] Preferably, a protruding part is provided at the upper end of the end cover, and an arc-shaped groove for accommodating the feeding pipe is formed on the protruding part. The setting of the protruding part and the arc-shaped groove can support the feeding pipe.

[0016] After adopting the above technical solution, the beneficial effects of the present invention are as follows:

[0017] The present invention transports the feed into the feeding pipe through the feeding pipe, and then enters the cylinder body through the discharge pipe. Since there is an included angle between the discharge pipe and the feeding pipe, a spiral air flow is formed in the cylinder body. Due to the gravity of the feed, it falls to the bottom of the cylinder body. The tiny solid particles are captured on the cylinder wall, and the remaining powder and the separated gas are discharged from the cylinder body through the exhaust pipe, realizing the separation of material and gas. The feed is not easy to mildew. The feed enters the feeding housing through the feeding pipe. The driving mechanism rotates to drive the baffle to rotate, and the feed is thrown out from the blanking pipe. During use, the falling amount of the feed can be controlled by controlling the rotation speed of the driving mechanism. After the driving mechanism stops operating, the baffle can close the feeding housing and stop the blanking. BRIEF DESCRIPTION OF THE DRAWINGS
