Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of corn starch processing, and particularly relates to an extrusion equipment for producing biological latex from corn starch. BACKGROUND

[0002] In the field of degradable materials, biological latex gradually becomes an important substitute for traditional synthetic latex as an environmentally friendly product. In the production process, corn starch is often used as the main raw material. Through chemical modification and physical treatment means, the crystalline structure of starch is destroyed, and the viscosity is reduced, so as to improve the film-forming property and applicability. After corn starch is mixed with hydrochloric acid, sodium trimetaphosphate, acrylic acid, hydrogen peroxide and other additives, extrusion treatment needs to be carried out under high temperature and high pressure conditions to realize the crystal destruction and molecular structure recombination of starch particles, so as to provide a basis for subsequent crushing, drying and product preparation.

[0003] The traditional extrusion equipment is mainly a screw extruder. The screw extruder uses the structure of the screw or the spiral plate to provide a pushing force for the material, so that the material is continuously conveyed and extruded. However, due to the flowability of the material, the relative sliding between the material and the screw structure or the spiral plate is easy to occur, and the equipment cannot effectively push the material. That is, when the extrusion pressure provided by the equipment for the material exceeds a certain pressure value, the material will slip, so that the equipment has certain use limitations, and the compactness of the extruded material is low.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances. The present embodiment is written in a progressive manner.

[0031] As Figures 1 to 7As shown, the corn starch production of a kind of biological latex extruding equipment of the present application, including in horizontal plane the inside and outside of two fixed ring 1, two rotating seal ring 2 and feed channel 4 are distributed, two fixed ring 1 and two rotating seal ring 2 form closed space, and rotating seal ring 2 is rotatably arranged on fixed ring 1, the guide ring 3 between two rotating seal ring 2 is set, the guide ring 3 is synchronously moved with rotating seal ring 2, the guide ring 3 is the wave-shaped structure of several arc-shaped plates, the direction of adjacent two arc-shaped plates is opposite, adjacent two arc-shaped plates are in contact with two fixed ring 1 respectively, and adjacent three arc-shaped plates and corresponding fixed ring 1 form guide space;Two output ends of feed channel 4 are installed on two fixed ring 1 respectively, and feed channel 4 is used to transport material to the corresponding guide space of two fixed ring 1;Guide channel 5 is arranged on two fixed ring 1, the guide plate 6 is slidably inserted in guide channel 5, the end of guide plate 6 is in contact with guide ring 3, the outer wall of each guide channel 5 is provided with material collecting cone groove 7, material collecting cone groove 7 is in communication with guide channel 5 and closed space simultaneously, and discharge channel 8 is communicated and arranged on material collecting cone groove 7.

[0032] In the present application, the diameters of the two fixed rings 1 are different, the small-diameter fixed ring 1 is located inside the large-diameter fixed ring 1, the two fixed rings 1 are coaxially arranged, the two rotating seal rings 2 are located on the upper and lower sides of the fixed rings 1 respectively, the two fixed rings 1 and the two rotating seal rings 2 form a ring-shaped closed space, the guide ring 3 is located in the closed space and is fixedly connected with the rotating seal ring 2; the axis of the guide ring 3 is vertical, the projection shape of the guide ring 3 on the horizontal plane is wave-shaped, which can be regarded as a structure composed of a plurality of staggered arc-shaped plates, one side of each arc-shaped plate is close to one fixed ring 1 and away from the other fixed ring 1, so that each wave-shaped plate forms a guide space with the corresponding fixed ring 1, and the adjacent two guide spaces are located on the inner and outer sides of the guide ring 3 respectively; of course, a single arc-shaped plate cannot form a closed space with the corresponding fixed ring 1, and the two ends of the arc-shaped plate are still away from the corresponding fixed ring 1 by a certain distance, at this time, the adjacent two arc-shaped plates of the arc-shaped plate fill the distance, that is, the adjacent three arc-shaped plates can form a guide space with the corresponding fixed ring 1; since each guide space is independent of each other, each guide space can independently realize the material conveying function.

[0033] The feeding channel 4 and the guide channel 5 are respectively located on the left and right sides of the fixed ring 1, the two output ends of the feeding channel 4 are respectively communicated with the two fixed rings 1 installed on the side walls, so that the feeding channel 4 can guide the material into the material guiding spaces on the left and right sides of the material guiding ring 3, thereby fully utilizing the material guiding spaces on the left and right sides of the material guiding ring 3; the guide channel 5 is installed on the side wall of the fixed ring 1 along the radial direction of the fixed ring 1, and the guide channel 5 is communicated with the closed space, the material blocking plate 6 can slide in the guide channel 5 and move along the radial direction of the fixed ring 1, and since the material blocking plate 6 is in abutment with the material guiding ring 3, when the material guiding ring 3 moves, the material guiding ring 3 can push the material blocking plate 6 to reciprocate along the radial direction of the fixed ring 1.

[0034] In use, the two rotating sealing rings 2 and the material guiding ring 3 perform circumferential motion, the feeding channel 4 guides the material into the material guiding spaces on the left and right sides of the material guiding ring 3 in the closed space, and the material guiding ring 3 carries the material to perform circumferential motion, when the material moves to the position of the material blocking plate 6, since the material blocking plate 6 is in abutment with the material guiding ring 3, the material blocking plate 6 can intercept the material in the material guiding space, at this time, the intercepted material is discharged through the material collecting cone groove 7 and the material discharging channel 8, thereby achieving the material discharging work, and the two material blocking plates 6 can cooperate to block and discharge the material in the material guiding spaces on the left and right sides of the material guiding ring 3; since each material guiding space is relatively independent, the blocking of the material by the material blocking plate 6 will not cause the material to move into the adjacent material guiding space, that is, the movement of the material guiding space can provide direct and effective extrusion pushing action for the material discharging, and by utilizing the continuous rotation of the material guiding ring 3, a plurality of material guiding spaces can continuously pass through the material blocking plate 6 and be discharged, thereby achieving the continuous extrusion conveying work of the material; in order to provide a high-temperature environment for the material, an electric heating structure or other heating structure can be additionally installed on the two fixed rings 1.

[0035] By adopting the cooperation of the material guiding ring 3 and the fixed ring 1, a plurality of material guiding spaces are formed between the material guiding ring 3 and the fixed ring 1, and by utilizing the rotational motion of the material guiding ring 3, each material guiding space can pass through the position of the material blocking plate 6 in turn, the material blocking plate 6 blocks the material in the material guiding space, and in cooperation with the rotation of the material guiding ring 3, the arc surface on the material guiding ring 3 extrudes the material, thereby achieving a direct and effective extrusion effect on the material, avoiding the problem that the flow of the material causes the extrusion force of the equipment on the material to be insufficient and the compactness of the material to be insufficient, improving the direct efficiency of the material extrusion work, and at the same time, by utilizing the cooperation of the two fixed rings 1 and the material guiding ring 3 and the setting mode that the material guiding spaces are formed on the left and right sides of the material guiding ring 3, a double conveying effect of the material can be achieved, thereby improving the work efficiency.

[0036] Further, two assembly grooves 9 are formed on the end face of the rotating sealing ring 2 facing the fixed ring 1, the end of the fixed ring 1 is slidably installed in the corresponding assembly groove 9, the guide channel 5 is in sliding contact with the end face of the rotating sealing ring 2, and the part of the end face of the rotating sealing ring 2 on the outside of the two fixed rings 1 is provided as a low face 10, and the guide channel 5 is in sliding contact with the low face 10.

[0037] The thickness of the middle position of the partial section of the fixed ring 1 is greater than the thickness of the fixed ring 1 on which the low surface 10 is located, so that the upper and lower side end surfaces of the guide channel 5 can abut against the corresponding low surface 10, and the upper and lower side end surfaces of the material blocking plate 6 can abut against the end surface of the corresponding fixed ring 1, so that the guide channel 5 wraps the material blocking plate 6 in it. If the low surface 10 is not provided, the end surface of the fixed ring 1 is a plane, and when the guide channel 5 abuts against the end surface of the fixed ring 1, the material blocking plate 6 cannot abut against the end surface of the fixed ring 1 due to the wall thickness of the guide channel 5. At this time, the gap between the material blocking plate 6 and the end surface of the fixed ring 1 will cause the loss of materials, and cannot provide direct and effective extrusion effect for the materials in the material guiding space. The fixed ring 1 and the rotating sealing ring 2 are combined through the assembly groove 9, so as to provide effective support for the fixed ring 1 and improve the connection strength between the fixed ring 1 and the rotating sealing ring 2. In some embodiments, in order to further improve the connection strength, a horizontal outer edge can be provided on the end portion of the fixed ring 1, and a groove, a pressing sheet or the like structure matched with the outer edge is provided on the rotating sealing ring 2, which can be realized on the basis of the prior art.

[0038] Further, the extrusion equipment further comprises a bottom plate 11, a plurality of support frames 12 and a power unit are arranged on the bottom plate 11, the support frames 12 are fixedly connected with the two fixed rings 1, and the power unit is used for providing power for the rotating movement of the two rotating sealing rings 2. The shape of the support frame 12 is U-shaped, the two fixed rings 1 can pass through the support frame 12, and the two ends of the support frame 12 are fixedly connected with the two fixed rings 1, so that the two fixed rings 1 can be fixedly supported by the plurality of support frames 12, the bottom plate 11 can support the plurality of support frames 12 and the power unit, and the power unit can provide power for the rotation of the two fixed rings 1.

[0039] Further, the bottom plate 11 is provided with a guide frame 13, the guide frame 13 is slidably provided with a movable frame 14 in the radial direction of the fixed ring 1, and the movable frame 14 is connected with the two material blocking plates 6. When the material guiding ring 3 rotates, because the distance between different positions on the material guiding ring 3 and the axis of the fixed ring 1 is different, the material guiding ring 3 will push one material blocking plate 6 to move, and the material blocking plate 6 can drive another material blocking plate 6 to move synchronously through the movable frame 14, so that the two material blocking plates 6 can keep the working mode of cooperating with the material guiding ring 3, and avoid that when one material blocking plate 6 is pushed to move by the material guiding ring 3, the other material blocking plate 6 is separated from the material guiding ring 3, thereby improving the synchronism of the movement of the two material blocking plates 6. Moreover, this structure only needs to use the movement of the material guiding ring 3 to provide power for the reciprocating movement of the two material blocking plates 6, and the material guiding ring 3 and the material blocking plate 6 can keep abutting at any time. When the material blocking plate 6 moves, it will drive the movable frame 14 to slide on the guide frame 13, and the guide frame 13 supports and guides the movable frame 14 and the material blocking plate 6, and the movement direction of the movable frame 14 is along the radial direction of the fixed ring 1.

[0040] Further, the material blocking plates 6 slide on the movable frame 14, and the material blocking plates 6 are connected with the movable frame 14 through the elastic bodies 15. Due to the shape characteristics of the material guiding ring 3, when the material guiding ring 3 is cut in the vertical plane where the diameter of the fixed ring 1 is located, the section width of the material guiding ring 3 at different positions is inconsistent, that is, when the two material blocking plates 6 are moved under the pushing action of the material guiding ring 3, the distance between the two material blocking plates 6 changes. If the two material blocking plates 6 are fixedly connected with the movable frame 14, the two material blocking plates 6 will be stuck with the material guiding ring 3. Therefore, in order to ensure the normal use of the equipment, the distance between the two material blocking plates 6 needs to be automatically adjusted. By using the sliding arrangement of the material blocking plates 6 on the movable frame 14 and the elastic pushing force provided by the elastic bodies 15 for the material blocking plates 6, the material blocking plates 6 and the material guiding ring 3 can be kept in abutting state, and the distance between the two material blocking plates 6 can be changed.

[0041] Further, the extrusion equipment further comprises an air suction unit, the air suction unit comprises negative pressure chambers 16 arranged on the side walls of the fixed rings 1, the negative pressure chambers 16 are communicated with the closed space through filter screens 17, and negative pressure pipes 18 are arranged on the two negative pressure chambers 16.

[0042] At the position close to the feeding channel 4, when the material is introduced into the material guiding space through the feeding channel 4, the air in the material guiding space needs to be discharged. In order to improve the storage amount of the material in the material guiding space, the air in the material guiding space which moves to the position of the feeding channel 4 can be sucked away through the negative pressure pipes 18 and the two negative pressure chambers 16, so that a negative pressure is formed in the material guiding space, and the material is sucked into the material guiding space by the negative pressure. In this way, the air discharge requirement is met, and the amount of material in the material guiding space is increased. The filter screen 17 is mainly used to intercept the material to prevent the material from entering the negative pressure chambers 16 and the negative pressure pipes 18.

[0043] Further, the output end of the negative pressure pipe 18 is provided with a multi-way pipe 19, the multi-way pipe 19 is close to the guide channel 5, two output ends of the multi-way pipe 19 are communicated with the closed space through the two fixed rings 1, and the bottom plate 11 is provided with an air pump 20, and the input end of the air pump 20 is communicated with the multi-way pipe 19.

[0044] When the material in the material guiding space is blocked by the material blocking plate 6, the material guiding space needs to be filled with air, otherwise a vacuum will be formed to hinder the relative movement of the material guiding ring 3 and the material blocking plate 6; the air in the material guiding space at the positions of the negative pressure pipe 18, the negative pressure chamber 16 and the feeding channel 4 can be extracted by the air pump 20 and the multi-way pipe 19, and at the same time, the air in the negative pressure pipe 18 can be supplemented into the material guiding space which is blocked by the material blocking plate 6, so that even if a negative pressure is formed in the material guiding space, the negative pressure value will not reach a vacuum state; in actual use, the negative pressure value can be set to a small value, which only needs to meet the air extraction and a small amount of material suction effect in the material guiding space near the feeding channel 4.

[0045] Further, the power unit comprises a transmission column 21 and a motor 22 arranged on the bottom plate 11, the transmission column 21 is in transmission connection with the circumferential outer wall of the two rotating sealing rings 2, the output ends of the transmission column 21 and the motor 22 are respectively provided with bevel gear one 23 and bevel gear two 24, the bevel gear one 23 and the bevel gear two 24 are in transmission connection with each other; the transmission column 21 is rotatably installed on the bottom plate 11, the motor 22 is fixed on the bottom plate 11, the transmission column 21 is in transmission connection with the circumferential outer wall of the two rotating sealing rings 2 at the same time, the motor 22 can provide power for the rotation of the transmission column 21 through the bevel gear one 23 and the bevel gear two 24, so that the rotating sealing ring 2 and the material guiding ring 3 perform circumferential movement.

[0046] The above is only the preferred embodiment of the present application, it should be noted that for those skilled in the art, without departing from the technical principles of the present application, a number of improvements and modifications can be made, these improvements and modifications should also be considered as the protection scope of the present application.
