5results about How to "Control feeding speed" patented technology

This utility model relates to the field of feed feeding technology, providing a feeding device suitable for the initial feeding of fish fry in factory-farmed aquaculture. The device includes a base, a feed storage bin, a spotlight, a conduit, a suction pump, and a particle detector. The feed storage bin is located on the base and holds the feed; the spotlight has a through-hole; the first end of the conduit connects to the feed storage bin, and the second end of the conduit connects to the spotlight through the through-hole; the suction pump is located in the conduit and is used to draw feed to the through-hole; the particle detector is located in the conduit and is used to detect the amount of feed flowing through. This utility model, by setting up a feed storage bin and a spotlight connected by a conduit, allows feed to flow through the conduit to the through-hole; the suction pump in the conduit regulates the flow rate of the feed to control the feeding speed; and the particle detector accurately detects the amount of feed flowing through, improving feeding accuracy and benefiting the fry rearing stage; it can control the feeding speed and quantity, reduce labor costs, make operation more convenient, and improve the survival rate of fry rearing.

The utility model relates to the technical field of punching devices, and provides a glass fiber reinforced plastic cable bridge punching device which comprises a punching table, a lower die block, an upper die block, a feeding plate, a rotating roller, a supporting cylinder, a moving plate and a control plate, the lower die block is installed at the top end of the punching table, and the upper die block is installed on the upper side of the lower die block in a sliding mode through a driving base. The glass fiber reinforced plastic cable bridge is conveniently punched through cooperation of the driving base, the upper module, the lower module and the punching head, a plurality of bottom columns are fixedly connected to the bottom end of the punching table, the feeding plate is fixedly connected to one side of the punching table, and a plurality of rotating rollers are rotationally installed on the feeding plate. The top ends of the multiple rotating rollers are flush with the top end of the lower module, the glass fiber reinforced plastic cable bridge can be stably placed and fed conveniently, and the supporting cylinder is installed on the upper side of the feeding plate. By means of the technical scheme, the problem that in the prior art, the punching feeding speed is inconvenient to control is solved.

The utility model discloses an impurity removal device for composite carbon source production, which comprises a tank body, a first sieve plate, a second sieve plate and a third sieve plate are sequentially arranged in the tank body from top to bottom, sieve holes are formed in the upper end surfaces of the first sieve plate, the second sieve plate and the third sieve plate, and the sizes of the sieve holes are sequentially reduced from top to bottom. A cover body is arranged on the upper end face of the tank body, a motor is arranged on the upper end face of the cover body, the output end of the motor penetrates through the cover body and is provided with a rotating shaft, and the rotating shaft is rotationally mounted with a first sieve plate, a second sieve plate and a third sieve plate, so that a user can add a composite carbon source needing impurity removal into the tank body; and then a motor is started to enable a rotating shaft to drive stirring blades to rotate, so that the composite carbon sources on the first sieve plate, the second sieve plate and the third sieve plate are stirred, the composite carbon sources rapidly leak out, impurities are blocked at the upper ends of the first sieve plate, the second sieve plate and the third sieve plate, and the impurity removal effect is achieved.

The utility model discloses a feeding device for preparing aluminum, titanium and boron, which belongs to a feeding device in the technical field of smelting equipment, and adopts the technical scheme that the feeding device comprises a stock bin which comprises a barrel body and a conical barrel which are sequentially arranged from top to bottom; a cover door pipe opening is formed in the top of the stock bin, and the air leakage cover door is detachably arranged on the cover door pipe opening; a pipeline assembly is arranged at the bottom of the conical barrel and comprises a first pipeline, a second pipeline and a third pipeline which are communicated with the conical barrel; a first valve is arranged on the first pipeline, and a second valve is arranged on the second pipeline; one end, communicated with the interior of the barrel body, of the third pipeline is arranged in the barrel body and is provided with a third valve; according to the feeding device for preparing aluminum, titanium and boron, the corresponding pipeline assemblies are arranged in the stock bin, potassium fluotitanate and potassium fluoborate are conveyed into the medium-frequency induction furnace to be fully reacted with molten aluminum, and therefore the quality of aluminum, titanium and boron alloy is improved.

This utility model discloses a feeding mechanism for molding sand production, relating to the technical field of feeding mechanisms. A feeding assembly is fixedly installed on the upper surface of the top of four support plates. A feeding pipe is fixedly installed on the lower surface of the feeding assembly, and a feed hopper is fixedly installed on the upper surface of the feeding assembly. A guide pipe is fixedly installed on the right side of the feed hopper, and an elevator is fixedly installed at the right end of the guide pipe. This utility model uses a motor to drive a rotating shaft and an auger to rotate, lifting the sand inside the machine body into the guide pipe. Simultaneously, the rotating shaft drives the auger to rotate, breaking up any clumps of sand. A feeder facilitates replenishment by the elevator. A motor drives a rotating shaft and an auger to rotate, conveying the sand from the right side of the machine body into the machine body. Simultaneously, the cutting blade on the rotating shaft rotates to cut large pieces of sand, preventing blockages during sand feeding, reducing cleaning workload, and improving work efficiency.
