Description

Technical Field

[0001] The invention relates to the technical field of centrifugal equipment, in particular to raw material biological centrifugal separation equipment for organic feed production. Background Art

[0002] The reason why organic feed raw materials need centrifugal separation is that centrifugal separation technology can effectively separate substances with different specific gravities, improve separation efficiency, and thus improve the quality and nutritional value of feed. Centrifugal separation technology uses centrifugal force. The strong centrifugal force generated by high-speed rotation accelerates the sedimentation rate of particles in the liquid and separates substances with different sedimentation coefficients and buoyancy densities in the sample. This technology is particularly suitable for separating heterogeneous systems with small density difference between the two phases, large viscosity, and fine particle size, because it takes a long time to separate these systems in a gravity field, and it may not even be completely separated. Through centrifugal separation, a better separation effect than gravity sedimentation can be obtained in a shorter time, thereby improving the purity and nutritional value of feed raw materials.

[0003] In the prior art, when separating mixed raw materials of organic feed, a centrifuge is usually used to separate them in layers in water by relying on the different densities of different particles. However, in this process, after the raw materials are separated, the raw materials in the upper and lower layers of the inner cylinder of the centrifuge need to be collected. The conventional collection process is to separate by pouring out manually. This separation method is prone to residues, which in turn affects the collection effect. Summary of the invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a biological centrifugal separation equipment for raw materials for organic feed production to solve the problems raised in the above-mentioned background technology. The present invention has a novel structure. A first collecting cloth and a second collecting cloth are arranged inside the inner cylinder to collect the raw materials on the upper and lower layers after the inner cylinder is centrifuged, respectively. The collected raw materials can be drained to avoid the problem of residual raw materials or incomplete collection, thereby facilitating the separate collection and use of organic feed raw materials.

[0006] Furthermore, a motor is fixed on the other side of the top of the base, and a transmission belt is installed at the output end of the motor. The other end of the transmission belt is driven and sleeved on the shaft rod of the rotating seat passing through the centrifuge box.

[0007] Furthermore, the upper inner wall of the centrifuge box and the top outer wall of the inner cylinder are both fixed with support rings, and the support ring of the inner cylinder is pressed on the top of the support ring of the centrifuge box. Two vertical rods are symmetrically fixed on the top of the rotating seat, and the vertical rods slide through the support rings of the inner cylinder and the centrifuge box.

[0008] Furthermore, a swivel is rotatably mounted on the inner wall of the top cover via a bearing, and a sleeve is fixed at the position of the swivel corresponding to the vertical rod, the top of the vertical rod is inserted into the sleeve, and the bottom of the sleeve is in compression contact with the supporting ring of the inner tube.

[0009] Furthermore, the collecting component also includes a connecting plate, a connecting plate is provided at the middle position of the bottom of the first circular ring, both ends of the connecting plate are fixedly connected to the first collecting cloth, a sealing box is fixed at the bottom of the connecting plate, and two tooth plates are slidably inserted inside the sealing box, and the two tooth plates are staggered.

[0010] Furthermore, rubber bands are fixed on the inner surfaces of the first collecting cloth on both sides of the connecting plate, and the outer ends of the tooth plates are fixedly connected to the middle position of the rubber bands. Magnet blocks are equidistantly provided on the surface of the rubber bands, and the magnet blocks of the rubber bands can be adsorbed on the surface of the connecting plate.

[0011] Furthermore, a gear is rotatably installed between the two tooth plates in the sealing box through a bearing, and both sides of the gear are meshed with the tooth plates. A rotating rod is fixed at the position of the gear on the top of the connecting plate, and a rotating knob is fixed on the top of the rotating rod beyond the inner tube, and the bottom of the rotating rod is fixedly connected to the gear.

[0012] Furthermore, a horizontal plate is slidably sleeved on the top surface of the rotating rod, and pull rods are fixed to the bottoms of both ends of the horizontal plate. The pull rods slide through the first circular ring and are fixedly connected to the second circular ring.

[0013] Furthermore, plug posts are fixed on both sides of the outermost end of the horizontal plate, and the plug posts slide into the interior of the inner tube. A spring clip is installed on the top of the inner tube corresponding to the insertion position of the plug posts, and the spring clip is in compression contact with the upper end of the horizontal plate.

[0014] Furthermore, a drainage hole is provided on the outer side of the inner wall of the inner cylinder corresponding to the sealing ball insertion position, and the radius of the drainage hole is larger than the radius of the sealing ball. A fixing plate is fixed to the rear end of the drainage hole, and a spring telescopic rod is fixed on the surface of the fixing plate. The extended end of the spring telescopic rod is fixed to the sealing ball.

[0015] Beneficial effects of the present invention:

[0016] 1. When the first ring of the present invention moves upward, it will squeeze the sealing ball, and the spring telescopic rod will retract the sealing ball into the drainage hole. At this time, the water in the inner cylinder will be discharged through the drainage hole and sent out through the drainage pipe. At the same time, it is also convenient for the raw materials on the upper layer to be lowered to facilitate collection inside the first collecting cloth. At the same time, when the second ring moves upward, the inner cylinder will release water for the second time. The water release process can further lower the water level, which is convenient for draining and drying the raw materials in the first collecting cloth and the second collecting cloth.

[0017] 2. When the pull rod pulls the second ring to move, the plug post simultaneously moves outward along the inside of the inner tube to guide and limit the second ring. The spring clip is clamped to facilitate the position of the entire collection assembly.

[0018] 3. Before centrifugation, the two misaligned tooth plates of the present invention extend out of the sealing box to push the rubber band against the inner wall of the inner cylinder. At this time, the first collecting cloth is also in an open state, so that after separation is completed, when the first collecting cloth and the first ring are moved upward by pulling the rotating rod, the raw materials in the lower layer will not be collected by mistake. Before approaching the upper raw materials, the knob is turned, and the rotating rod drives the gear to rotate. The gear engages with the tooth plates on both sides, and the tooth plates drive the rubber band to shrink and approach the connecting plate. The magnet block on the inner side of the rubber band is adsorbed on the connecting plate to achieve sealing of the bottom of the first collecting cloth, so that the raw materials on the upper end of the inner cylinder are collected by the first collecting cloth in a sealed state.

[0019] 4. The present invention uses two pull rods to drive the second ring to move, and collects the raw materials in the lower layer through the second collecting cloth in a closed state. After all the inner tubes are taken out, the binding ropes at the bottom of the first collecting cloth and the second collecting cloth are opened to collect the raw materials with different densities separately.

[0020] 5. The top supporting ring of the inner cylinder of the present invention is in squeeze contact with the supporting ring of the centrifugal box and is limited by the insertion of the vertical rod. When the rotating seat rotates, the inner cylinder can be driven to rotate centrifugally. The sleeve on the rotating ring on the inner wall of the top cover is sleeved on the top of the vertical rod and limits the supporting ring of the inner cylinder, thereby maintaining the stability of the inner cylinder during rotation and facilitating the removal of the inner cylinder.

[0021] 6. Compared with the prior art, the present invention sets a first collecting cloth and a second collecting cloth inside the inner cylinder to collect the raw materials in the upper layer and the lower layer respectively after the inner cylinder is centrifuged. The collected raw materials can be drained to avoid the problem of residual raw materials or incomplete collection, which is convenient for the separate collection and use of organic feed raw materials.
