[0002] The papermaking industry is an important part of industrial production. Pulp processing, as a key link in papermaking production, has a direct impact on the quality and production efficiency of pulp. In the pulp processing process, industrial filter cloths and filter screens are usually used as key equipment to perform solid-liquid separation.

[0003] However, the industrial filter cloths and filter screens currently used in the pulp separation process need to be cleaned internally by a special cleaning cart after a period of treatment. The entire cleaning and maintenance cycle is relatively long and requires downtime, resulting in reduced production efficiency and a relatively short service life. A large amount of cleaning fluid is consumed during the cleaning process, and the later use cost is relatively high. Summary of the invention

[0004] The technical problem to be solved by the present invention is that currently, the centrifugal filtration needs to be shut down for maintenance, which leads to reduced production efficiency and high maintenance costs.

[0005] The technical solution adopted by the present invention to solve its technical problems is: a separation type material guiding mechanism applied to a centrifuge, comprising a centrifuge casing and a transverse spiral shaft installed inside the centrifuge casing, a centrifugal separation blade is arranged inside the centrifuge casing at the left end of the transverse spiral shaft, a lateral linkage gear of an integral structure is axially fixed on the left side of the centrifugal separation blade, a lateral speed-increasing gear set is arranged on the periphery of the lateral linkage gear, the transverse spiral shaft penetrates the centrifugal separation blade through a synchronous shaft and is transmission-connected to the lateral speed-increasing gear set, a plurality of lateral centrifugal material guiding channels are opened inside the centrifuge casing at the periphery of the centrifugal separation blade, an electrically controlled partition plate is arranged inside the centrifuge casing between the transverse spiral shaft and the centrifugal separation blade, and electrically controlled isolation plates are respectively arranged on both sides of the connecting end of the lateral centrifugal material guiding channel and the centrifugal separation blade.

[0006] The lateral speed-increasing gear set includes a control wheel axially fixed on the left side of the synchronization shaft, an annular offset gear fixed on the right side edge of the control wheel, a lateral linkage shaft and transmission gears axially fixed on both ends of the lateral linkage shaft.

[0007] The centrifuge housing is internally provided with a material guide chamber for arranging a transversely placed spiral shaft, a centrifugal chamber for arranging centrifugal separation blades, and a transmission chamber for arranging a lateral speed-increasing gear set.

[0008] A lateral telescopic groove for installing an electrically controlled partition plate is provided inside the centrifuge casing between the material guiding chamber and the centrifugal chamber.

[0009] The electrically controlled partition plate includes an adjusting screw installed inside a lateral telescopic groove, a driving gear axially fixed to the outer end of the adjusting screw, a main control ring meshing with the driving gear for transmission, an external motor for controlling the rotation of the main control ring, an internal telescopic block threadedly sleeved on the outside of the adjusting screw, an external sealing plate fixed to the outside of the internal telescopic block, and an electrically controlled closing cover installed on both sides of the external sealing plate.

[0010] The outer sealing plate is symmetrically provided with first receiving grooves on both sides, and the electrically controlled closing cover comprises a lateral closing plate movably installed and a first adjusting support rod movably installed in the first receiving groove.

[0011] The electrically controlled isolation plate comprises an arc-shaped isolation cover plate movably mounted on one side of the connecting end between the lateral centrifugal material guide channel and the centrifugal separation blade and a second adjustment support rod.

[0017] (2) By adopting an outer design for the lateral speed-increasing gear set, it is convenient for later maintenance and can be kept away from the reaction chamber to ensure its durability;

[0018] (3) By adopting the design of electrically controlled partition plates and electrically controlled isolation plates, the internal chamber can be formed into a closed chamber, thereby improving the internal insulation performance and reducing energy waste;

[0019] (4) The size of the feed opening can be adjusted by adjusting the electrically controlled partition plate, which can not only control the feed amount, but also cut off the feed chamber and the centrifugal chamber after the feed is completed, thereby improving the centrifugal efficiency;

[0020] (5) A circulating heat exchange flow channel is set inside the horizontal spiral shaft and the centrifugal separation blades, and the internal heat exchange oil operation is controlled according to the rotation speed of the centrifugal separation blades themselves, greatly improving its resource recovery and utilization rate;

DETAILED DESCRIPTION

[0030] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A separation-type material guiding mechanism applied to a centrifuge is shown, comprising a centrifuge casing 1 and a transverse spiral shaft 2 installed inside the centrifuge casing 1, a centrifugal separation blade 3 is arranged inside the centrifuge casing 1 at the left end of the transverse spiral shaft 2, a lateral linkage gear 4 of an integral structure is axially fixed on the left side of the centrifugal separation blade 3, a lateral speed-increasing gear set 5 is arranged on the periphery of the lateral linkage gear 4, the transverse spiral shaft 2 penetrates the centrifugal separation blade 3 through a synchronous shaft 6 and is transmission-connected to the lateral speed-increasing gear set 5, five lateral centrifugal material guiding channels 7 are opened inside the centrifuge casing 1 at the periphery of the centrifugal separation blade 3, an electrically-controlled partition plate 8 is arranged inside the centrifuge casing 1 between the transverse spiral shaft 2 and the centrifugal separation blade 3, and electrically-controlled isolation plates 9 are respectively arranged on both sides of the connecting end of the lateral centrifugal material guiding channel 7 and the centrifugal separation blade 3.

[0033] Working principle: People introduce the pulp mixture into the centrifuge housing 1, and then drive the horizontal screw shaft 2 to rotate, so as to control the raw material to be transported from right to left, and introduce it into the separation surface on the right side of the centrifugal separation blade 3. The centrifugal separation blade 3 is driven to rotate at high speed through the lateral speed-increasing gear set 5, and the introduced raw material is quickly separated outward to the inside of the lateral centrifugal guide channel 7, and then the material is discharged. After the processing is completed, the internal chamber is isolated by the electric control style board 8 and the electric control isolation board 9 to be suitable for operations at different stages, and the internal heat can also be insulated and stored. By changing the position of the electric control style board 8 and the electric control isolation board 9, the feed and discharge amounts can be adjusted with lower energy consumption without adjusting the speed of the horizontal screw shaft 2.

[0034] In order to cooperate with the lateral speed increase adjustment, the lateral speed increase gear set 5 includes a control wheel 51 axially fixed on the left side of the synchronization shaft 6, an annular offset gear 52 fixed on the right side edge of the control wheel 51, a lateral linkage shaft 53 and a transmission gear 54 axially fixed at both ends of the lateral linkage shaft 53.

[0035] The lateral linkage shaft 53 is respectively meshed with the annular eccentric gear 52 and the lateral linkage gear 4 through the transmission gears 54 at both ends. The diameter of the annular sheet gear 52 is larger than the diameter of the lateral linkage gear 4. When the synchronous shaft 6 rotates, the centrifugal separation blade 3 can rotate at a high speed.

[0036] In order to facilitate internal assembly, the centrifuge housing 1 is provided with a material guide chamber for arranging the transverse screw shaft 2 , a centrifugal chamber for arranging the centrifugal separation blades 3 , and a transmission chamber for arranging the lateral speed-increasing gear set 5 .

[0037] In order to facilitate lateral storage, a lateral telescopic groove 10 for installing the electrically controlled partition plate 8 is provided inside the centrifuge housing 1 between the material guiding chamber and the centrifugal chamber.

[0038] In order to cooperate with the lateral telescopic closing, the electrically controlled partition plate 8 includes an adjusting screw 81 installed inside the lateral telescopic groove 10, a driving gear 82 axially fixed to the outer end of the adjusting screw 81, a main control ring 83 meshing with the driving gear 82, an external motor 84 for controlling the rotation of the main control ring 83, an internal telescopic block 85 threadedly sleeved on the outside of the adjusting screw 81, an external sealing plate 86 fixed to the outside of the internal telescopic block 85, and an electrically controlled closing cover 87 installed on both sides of the external sealing plate 86.

[0039] In order to cooperate with the external motor 84 to drive the main control ring 83 to rotate by driving the gear on the motor shaft, and then the main control ring 83 drives the driving gear 82 at the outer end of the adjusting screw 81 to rotate, thereby controlling the internal telescopic blocks 85 at all positions to perform synchronous telescopic sliding. When the internal telescopic block 85 slides toward the outer opening of the lateral telescopic groove 10, the external sealing plates 86 are combined with the synchronous shaft 6 to form a closed baffle, thereby separating the material guide chamber and the centrifugal chamber; similarly, when the adjusting screw 81 rotates in the opposite direction and drives the internal telescopic block 85 to slide toward the inner side of the lateral telescopic groove 10, the external sealing plate 86 and the synchronous shaft 6 are separated from each other, and the material guide chamber and the centrifugal chamber remain connected.

[0040] In order to facilitate lateral storage, first storage grooves are symmetrically opened on both sides of the external sealing plate 86, and the electrically controlled closing cover 87 includes a lateral closing plate 871 movably installed and a first adjustment support rod 872 movably installed in the first storage groove.

[0041] When the external sealing plate 86 retracts to the inner side of the lateral expansion groove 10, the first adjusting strut 872 extends to control the lateral closing plate 871 to flip toward the opening of the lateral expansion groove 10, thereby closing the opening of the lateral expansion groove 10 to prevent the pulp mixture from flowing into the inside of the lateral expansion groove 10 during transportation.

[0042] In order to ensure that the outer sealing plate 86 can reduce the opening size of the lateral expansion slot 10 as much as possible when it is stored, the lateral expansion slot 10 is prevented from being blocked by raw materials.

[0043] In order to adjust the flow rate of the connecting port of the lateral centrifugal guide channel 7, the electrically controlled isolation plate 9 includes an arc-shaped isolation cover plate 91 and a second adjustment support rod 92 movably mounted on one side of the connecting end of the lateral centrifugal guide channel 7 and the centrifugal separation blade 3.

[0044] The second adjustment support rod 92 controls the arc-shaped isolation cover plate 91 to be turned over and adjusted by telescoping, so as to change the size of the connecting port. The arc-shaped isolation cover plate 91 can also be changed into a screen plate with a discharge hole inside, so as to change the diameter of the fiber after centrifugal separation by the centrifugal separation blade 3. When blockage occurs, it can be turned outward and the screen plate can be blown through by spraying high-pressure air through the self-maintenance nozzle on the lateral inner wall, so as to complete maintenance. The way to detect blockage is the pressure inside the lateral centrifugal guide flow channel 7 when the centrifugal separation blade 3 rotates.

[0045] In order to recover and utilize the internal temperature, the transverse spiral shaft 2 , the centrifugal separation blades 3 and the synchronous shaft 6 are all provided with internal flow guide chambers 11 that are interconnected.

[0046] The internal flow guide chamber 11 is composed of a main through-flow channel opened at the center position inside the horizontal spiral shaft 2 and the synchronous shaft 6, a spiral heat exchange channel opened inside the horizontal spiral shaft 2 and located outside the main through-flow channel, a spiral heat return channel opened inside the lateral assembly disk of the centrifugal separation blade 3, and an internal circulation channel opened on the inner wall of the centrifuge housing 1. The internal circulation channel connects the left end opening of the main through-flow channel and the outer connecting surface opening of the spiral heat return channel, and the spiral heat exchange channel connects the right end opening of the main through-flow channel and the spiral heat return channel.

[0047] In order to facilitate the introduction of the melted raw materials into the interior of the centrifuge housing 1, the upper surface of the centrifuge housing 1 is provided with an upper feed pipe 12 which is connected to the interior of the material guide chamber.

[0048] In order to discharge the solid matter inside the lateral centrifugal guide channel 7 to the outside, a lateral discharge pipe 13 is installed on the outside of the centrifuge housing 1.

[0049] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
