The cooperation of the ring a19 with the groove a15 ensures that only a relative rotation and no relative axial movement occurs between the feed pipe 5 and the drum 13. A plurality of roller bearings 21 are matched between the rotary drum 13 and the inner wall of the shell 1, a rotary sealing structure 20 is arranged between the rotary drum 13 and the shell 1, solid dregs discharged from a dreg outlet C16 and a dreg outlet D17 are prevented from entering a gap between the rotary drum 13 and the shell 1 in a rotary fit mode, and liquid separated in a centrifugal mode is prevented from entering a gap between the rotary drum 13 and the shell 1 in a rotary fit mode.
The electric drive module 22 in the present invention adopts the prior art, and is mainly composed of a motor, a speed reducer and a control unit.
The axial distance between the spiral plate A11 and the spiral plate B12 is larger than the distance between two adjacent poking plates 42 in the switch mechanism 36, so that each poking plate 42 is only fixedly matched with the spiral plate A11 or the spiral plate B12.
The working flow of the double-path horizontal centrifugal equipment is as follows: when the centrifugal separation of the ground pulp in the production of the sterile bean curd is required, the electric drive module 22 is started to operate firstly, the electric drive module 22 drives the feeding pipe 5 to rotate rapidly through the gear A23 and the gear B24, and the feeding pipe 5 drives the rotary drum 13 to rotate at a speed faster than the feeding pipe 5 through the gear A25, the gear C26, the gear D28, the ring sleeve 29, the gear B32, the gear E33 and the gear F35, and the rotating direction of the rotary drum 13 is the same as the rotating direction of the feeding pipe 5, so that the feeding pipe 5 and the rotary drum 13 rotate relatively. Two shifting plates 42 on each switch mechanism 36 that are not adjacent are always engaged with the spiral plate a11 or the spiral plate B12.
If the screw plate a11 brings the corresponding belt 40 to open the tap hole C16 by pulling one set of non-adjacent two pulling plates 42 of the switching mechanism 36 in each tap hole C16, the screw plate B12 brings the corresponding belt 40 to close the tap hole C16 by pulling the other set of non-adjacent two pulling plates 42 of the switching mechanism 36 in each tap hole C16, the screw passage on the left side of the screw plate a11 communicates with the tap hole A2 when the switching mechanism 36 opens the tap hole C16, the screw plate a11 brings the belt 40 of the switching mechanism 36 in the tap hole D17 to close the tap hole D17 by interacting with the one set of non-adjacent two pulling plates 42 of the switching mechanism 36 in the tap hole D17, and the screw plate B12 brings the belt 40 of the switching mechanism 36 in the tap hole D17 to open the tap hole D17 by interacting with the other set of non-adjacent two pulling plates 42 of the switching mechanism 36, and the screw passage on the right side of the screw plate a11 communicates with the tap hole B3 when the switching mechanism 36 opens the tap hole D17.
The soybean milk ground by mixing water is continuously pressed into a spiral channel on the right side of a spiral plate A11 through a feed inlet A7 and a discharge outlet A8 at one end of a feed pipe 5, the soybean milk entering the spiral channel on the right side of the spiral plate A11 is centrifugally and solid-liquid separated under the common drive of a spiral pushing mechanism 53 rotating in the same direction at a high speed and a rotary drum 13, and separated liquid part passes through small holes densely distributed on the spiral plate A11 and the spiral plate B12, is discharged through a pulp discharge hole 18 on the rotary drum 13 and a pulp outlet 4 on a shell 1 and is intensively collected. Because the rotation speed of the feeding pipe 5 is different from that of the rotary drum 13, the feeding pipe 5 drives the spiral plate A11 and the spiral plate B12 to have relative rotation speed relative to the rotary drum 13, and separated solid residues are still positioned in the spiral channel on the right side of the spiral plate A11 and are pushed by the spiral plate A11 to axially move towards a plurality of slag outlets D17.
When the solid slag in the right spiral channel of the spiral plate A11 reaches the annular area where the slag holes D17 are located, as the spiral plate B12 drives the corresponding belt 40 to open the slag holes D17 through the action of the shifting plate 42 of the switching mechanism 36 in any slag hole D17, the solid slag in the right spiral channel of the spiral plate A11 is discharged to hot water below through the opened slag holes D17 and the slag holes B3 on the shell 1 under the extrusion of the subsequent solid slag to be uniformly stirred again.
The solid dregs after centrifugal separation are evenly mixed with hot water again and then pumped into the spiral channel on the left side of the spiral plate A11 through the feed inlet B9 and the discharge outlet B10 at the other end of the feed pipe 5. The materials entering the spiral channel on the left side of the spiral plate A11 are centrifugally and solid-liquid separated under the common drive of the spiral pushing mechanism 53 and the rotary drum 13 which rotate in the same direction at high speed, and the liquid part separated again passes through small holes densely distributed on the spiral plate A11 and the spiral plate B12, is discharged through the slurry discharging holes 18 on the rotary drum 13 and the slurry outlet 4 on the shell 1, and is collected together with the liquid part separated previously. The solid slag separated again is still located in the screw channel on the left side of the screw plate a11 and is pushed by the screw plate B12 axially towards the tapping holes C16.
When the solid slag, which is centrifuged again in the left side spiral channel of the spiral plate a11, reaches the annular area where the slag holes C16 are located, the solid slag in the left side channel of the spiral plate a11 is discharged through the opened slag hole C16 and the slag hole A2 on the shell 1 under the extrusion of the subsequent solid slag and finally collected as poultry feed as the spiral plate a11 drives the corresponding belt 40 to open the slag holes C16 by acting with the poking plate 42 of the switching mechanism 36 in any slag hole C16.
During the operation of the belt 40 in the operation of the switch mechanism 36, when the shifting plate 42 reaches the gap between the belt 40 and the inner wall of the box 37, the shifting plate 42 swings adaptively under the action of the box 37, the volute springs 46 resetting the shifting plate 42 are further compressed for energy storage, and the shifting plate 42 which is subjected to lodging breaks away from the corresponding swing limiting blocks 47 and enters the gap between the belt 40 and the box 37 along with the operation of the belt 40. When the poking plate 42 moves completely along with the belt 40 to the gap between the belt 40 and the frame 37, the poking plate 42 swings back instantaneously under the reset action of the corresponding spiral spring 46 to reset and contacts with the corresponding swing limiting block 47 again.
When the operation of the electric drive module 22 is stopped at the end of the use of the invention, the invention can carry out the circulating secondary centrifugal separation on the solid dregs mixed by hot water after the primary centrifugal separation in the sterile bean curd production process, reduce the quantity of centrifugal equipment and reduce the purchase cost of bean curd production equipment and the maintenance cost of the equipment.
In summary, the two-way horizontal centrifugal device: the double-path horizontal centrifugal device can synchronously and centrifugally separate materials which are subjected to solid-liquid separation for the first time and materials which are subjected to solid-liquid separation for the second time in the sterile bean curd production process, solid parts of the materials with different separation degrees are not mutually mixed in the centrifugal separation process, solid residues of the materials with different separation degrees after centrifugal separation are respectively discharged from different outlets, so that the materials subjected to centrifugal separation for the first time are subjected to effective secondary circulating centrifugal separation in the same device, the quantity of centrifugal separation devices is saved, and the purchase cost and the maintenance cost of the device are reduced.
The foregoing description is only one preferred embodiment of the invention, and therefore all changes and modifications that come within the meaning and range of equivalency of the structures, features and principles of the invention are intended to be embraced therein.
