Wherein, the upper end of the stirring barrel 41 is provided with a first mounting hole, a first feeding channel 411, a first discharging channel 412 and a first water inlet channel 413; a high-speed rotation shaft 42 passing through the first mounting hole and extending toward the inside of the stirring tub 41; the feeding mechanism 43 includes a differential 431 and a feeding screw 432, the feeding screw 432 rotates with the high-speed rotation shaft 42 through the differential 431, and the rotation speed of the feeding screw 432 is smaller than that of the high-speed rotation shaft 42; the stirring paddle 44 is vertically and fixedly connected with the lower end of the high-speed rotating shaft 42, and the rotating diameter of one end of the stirring paddle 44 away from the high-speed rotating shaft 42 is matched with the diameter of the inner cavity at the bottom of the stirring barrel 41.

Because the rotational speed of the feed screw 432 is smaller than the rotational speed of the stirring paddle 44, a coaxial asynchronous differential shearing motion is formed between the stirring paddle 44 and the feed screw 432, so that the raw material between the end of the feed screw 432 and the stirring paddle 44 can be rapidly taken away, the blockage phenomenon caused by raw material accumulation between the feed screw 432 and the stirring paddle 44 is prevented, and finally the rotating shaft 521 is damaged. Meanwhile, in the embodiment, the rotating diameter of one end of the stirring paddle 44, which is close to the inner wall of the stirring barrel 41, is adapted to the inner diameter of the stirring barrel 41, and the purpose of the arrangement is to enable the stirring paddle 44 to take away injection molding raw slurry, which is close to the inner wall of the stirring barrel 41, in the rotating process, so that the injection molding raw slurry is prevented from solidifying on the inner wall of the stirring barrel 41, the purpose of cleaning the inner wall of the stirring barrel 41 is achieved, and compared with the prior art, the stirring barrel 41 is cleaned without stopping for a period of time during continuous operation, thereby saving manpower and material resources and improving the production efficiency.

In this embodiment, the raw materials and water are mixed in the stirring chamber 416, and the injection molding raw slurry in the stirring chamber 416 is made to form high pressure by high-speed rotation of the stirring paddle 44, and finally flows into the gas separation device 50 in a short time through the first discharging channel 412 provided at the bottom of the stirring chamber 416. It will be appreciated by those skilled in the art that the inlet end of the first feed channel 411 may be provided with various means of communication with the outside, such as by means of a flange connection or a throat connection, etc., and may be specifically determined according to the previous process or the feeding mode.

In this embodiment, to further ensure that material does not form a plug between the feed screw 432 and the stirring screw 44, the diameter of the feed cavity 415 is set smaller than the diameter of the stirring cavity 416, so that material between the stirring screw 44 and the feed screw 432 can be quickly carried away by differential shearing movement between the stirring screw 44 and the feed screw 432. Meanwhile, in the embodiment, since the diameter of the feeding cavity 415 is smaller than that of the stirring cavity 416, when the outlet of the first water inlet passage 413 is arranged, the outlet of the first water inlet passage 413 should be close to the central position of the stirring cavity 416, so that the purpose of the arrangement is to further wash the raw materials between the stirring paddle 44 and the feeding screw 432, so that no residue of the raw materials exists between the stirring paddle 44 and the feeding screw 432, and meanwhile, the arrangement can prolong the mixing reaction time of the raw materials and water, and enable the chemical reaction between the raw materials to be more sufficient.

In this embodiment, the height of the stirring chamber 416 is also set to be compatible with the thickness of the stirring paddle 44. It will be appreciated by those skilled in the art that if the height of the stir chamber 416 is substantially greater than the thickness of the paddle 44, the high speed rotation of the paddle 44 within the stir chamber 416 makes it difficult to create a high pressure in the injection molding syrup, such that the injection molding syrup cannot be rapidly flowed from the first discharge channel 412 into the gas separation device 50, and the injection molding syrup formed after mixing the raw materials with water solidifies in a relatively short period of time, ultimately resulting in clogging of the stir chamber 416. Therefore, the height of the stirring cavity 416 is adapted to the thickness of the stirring paddle 44, and the specific matching relationship between the stirring cavity 416 and the stirring paddle 44 can be determined according to the ratio of the raw materials, and when the raw materials react with water faster due to the ratio of the raw materials, the gap between the stirring cavity 416 and the stirring paddle 44 should be properly smaller, otherwise, the gap between the stirring cavity and the stirring paddle can be properly larger.

Further, the stirring paddle 44 is composed of a connecting piece and a plurality of blades, the connecting piece is fixedly sleeved at the lower end of the high-speed rotating shaft 42, the blades are uniformly distributed along the circumferential direction of the connecting piece, the blades are in a hook shape, and the rotation of the stirring paddle 44 is consistent with the bending direction of the blades. It will be appreciated by those skilled in the art that the plurality of blades may be fixedly connected to the connector by welding or may be integrally formed, and in this embodiment, the blades are preferably integrally formed, so that the strength of the stirring paddle 44 may be increased. It will be further understood by those skilled in the art that the number of the blades may be three, four or five, and in this embodiment, two are preferred, and the number of the specific arrangements may be set according to needs, for example, when the number of the first discharging passages 412 is increased, the pressure provided by the stirring paddles 44 may be increased, and at this time, the number of the blades in the stirring paddles 44 may be appropriately increased to ensure the pressure in each discharging passage. In this embodiment, when the injection molding raw slurry in the stirring cavity 416 rotates in the stirring cavity 416 along with the stirring paddle 44, the injection molding raw slurry gathers towards the inner wall of the stirring cavity 416 under the action of centrifugal force, and as the stirring paddle 44 rotates, more and more raw materials attached to the inner wall of the stirring cavity 416, the injection molding raw slurry on the inner wall of the stirring cavity 416 is not easy to be removed and solidified finally. In order to prevent this phenomenon, the rotating diameter of the stirring paddle 44 near the inner wall of the stirring cavity 416 is adapted to the diameter of the stirring cavity 416, and the purpose of setting the blades to be bent and enabling the bending direction to be consistent with the rotating direction is to drive the injection molding raw slurry near the inner wall of the stirring cavity 416 to the rotating center of the circle in the rotating process of the stirring paddle 44. Simultaneously, the solidification phenomenon caused by excessive accumulation of injection molding raw pulp on the inner wall of the stirring cavity 416 is avoided, and the self-washing capacity of the stirring cavity 416 is further enhanced.

Further, the gas separation device 50 includes a housing 51 and a stirring disperser 52 provided inside the housing 51. Wherein, the shell 51 is provided with a second mounting hole, a second feeding channel 511, a second discharging channel 512, a second water inlet channel 513 and a water outlet channel 514, the second feeding channel 511 is communicated with the first discharging channel 412, the water outlet channel 514 is communicated with the first water inlet channel 413, and the second water inlet channel 513 is communicated with the water injection device; the stirring and dispersing device comprises a rotating shaft 521, and an exhaust paddle 522, a disperser 523 and a pressure paddle 524 which are coaxially and fixedly connected to the rotating shaft 521 in sequence from top to bottom, wherein the rotating shaft 521 can drive the exhaust paddle 522, the disperser 523 and the pressure paddle 524 to rotate, when the exhaust paddle 522 and the pressure paddle 524 rotate, air flow flowing to the exhaust paddle 522 is formed between the exhaust paddle 522 and the pressure paddle 524, and the rotating shaft 521 penetrates through the mounting hole and extends to the bottom of the shell 51. In the present embodiment, the water outlet channel 514 and the first water inlet channel 413 are communicated through a hose (not shown in the figure); the water injection means is a reservoir (not shown) which is in communication with the second water inlet channel 513 via a water pump.

In this embodiment, the injection molding raw slurry enters the disperser 523 from the second feeding channel 511, and the disperser 523 rotates at a high speed under the drive of the rotating shaft 521 to disperse the injection molding raw slurry entering the disperser 523, so that the gas contained in the injection molding raw slurry is separated from the injection molding raw slurry. Meanwhile, the upper and lower sides of the disperser 523 are provided with an exhaust paddle 522 and a pressure paddle 524, and when the two paddles rotate, air flowing to the exhaust paddle 522 is formed, air separated from the injection molding raw pulp flows to one side of the exhaust paddle 522 along with air flowing between the exhaust paddle 522 and the pressure paddle 524 and finally is discharged through the water outlet channel 514, and the remaining production raw pulp without air enters the stirring paddle 44 under the action of self gravity and finally enters the molding host 60 through the second discharging channel 512 under the high pressure formed by high-speed rotation of the pressure paddle 524. Thus, the gas in the injection molding stock is removed from the injection molding stock treated by the gas separation device 50 to form a final molded gas-free production stock, thereby ensuring that the final molded product has a smooth surface and a uniform density.

Further, an exhaust cavity 515, a dispersion cavity 516 and a pressure cavity 517 are coaxially arranged in the shell 51 from top to bottom in sequence, the diameter of the dispersion cavity 516 is smaller than the diameters of the exhaust cavity 515 and the pressure cavity 517, an exhaust paddle 522 is positioned in the exhaust cavity 515, the dispersion paddle is positioned in the dispersion cavity 516, and a pressure paddle 524 is positioned in the pressure cavity 517; the second feed channel 511 extends from the outer side wall of the dispersion chamber 516 into the dispersion chamber 516, the second discharge channel 512 extends from the inner side wall of the bottom of the pressure chamber 517 to the outer side wall of the bottom of the pressure chamber 517, the second feed channel 513 extends from the outer side wall of the dispersion chamber 516 into the discharge chamber 515, and the discharge channel 514 extends from the inner side wall of the discharge chamber 515 to the outer side wall of the discharge chamber 515. In this embodiment, the diameter of the dispersing chamber 516 is smaller than the diameters of the exhaust chamber 515 and the pressure chamber 517, so arranged as to prevent escape of the gas discharged after dispersing the injection molding syrup in the disperser 523. It will be appreciated by those skilled in the art that if the diameter of the dispersion chamber 516 is larger than that of the exhaust chamber 515 and the pressure chamber 517, then in the portion of the dispersion chamber 516 larger than that of the exhaust chamber 515 and the pressure chamber 517, the air discharged by the scattered injection molding raw slurry may enter the pressure chamber 517 together with the injection molding raw slurry, and finally enter the molding machine 60 under the action of the stirring paddle 44, so that the final gypsum lightweight hollow partition board has reduced surface smoothness and uneven density due to the inclusion of bubbles, and therefore in this embodiment, the diameter of the dispersion chamber 516 is smaller than that of the pressure chamber 517 and the exhaust chamber 515 to enable the exhaust to be more thorough, and ensure that the final gypsum lightweight hollow partition board has better quality.

Further, the exhaust paddle 522 and the pressure paddle 524 each include a connecting member and a plurality of blades, the connecting member is fixedly sleeved on the rotating shaft 521, the blades are fixedly connected on the connecting member, the blades are uniformly distributed along the circumferential direction of the connecting member, and the number of the blades of the exhaust paddle 522 is greater than the number of the blades of the pressure paddle 524. It will be appreciated by those skilled in the art that the blade and the connector may be integrally formed by welding, and in this embodiment are preferably integrally formed. In this embodiment, the pressure paddle 524 and the exhaust paddle 522 rotate coaxially, so that the pressure paddle 524 and the exhaust paddle 522 draw gas therebetween at the same time, and the number of blades in the exhaust paddle 522 is greater than the number of blades in the pressure paddle 524, so that the capacity of the exhaust paddle 522 to draw gas is greater than the capacity of the pressure paddle 524 to draw gas, and as a result, a gas flow from the pressure paddle 524 to the exhaust paddle 522 is formed between the exhaust paddle 522 and the stirring paddle 44, and finally, the scattered and separated gas in the injection molding raw slurry flows to the exhaust paddle 522 side along with the gas flow formed between the exhaust paddle 522 and the pressure paddle 524 and flowing to the exhaust paddle 522 by the pressure paddle 524. It will be appreciated by those skilled in the art that the difference in the number of blades in the discharge paddles 522 and 524 may be set according to specific needs, and that when the flow of injection molding stock in the second feed channel 511 is large, the difference in the number of blades in the discharge paddles 522 and 524 may be appropriately increased, or vice versa. It will be further appreciated by those skilled in the art that the number of blades in the pressure paddle 524 may be set according to the production requirement, and the number of blades in the pressure paddle 524 may be increased appropriately when the number of the second discharge passage 512 is large or the flow rate of the raw slurry produced in the second discharge passage 512 is large. In this embodiment, the number of blades of the pressure paddle 524 is preferably two, and the number of blades of the exhaust paddle 522 is preferably three.

In this embodiment, the blades of the pressure paddle 524 and the exhaust paddle 522 are both in a hook shape, and the rotation directions of the exhaust paddle 522 and the pressure stirring paddle 44 are both identical to the bending directions of the blades. Because of the high speed rotation of the disperser 523, the production stock is contained in both the pressure chamber 517 and the exhaust chamber 515, and the production stock in the pressure chamber 517 and the exhaust chamber 515 rotates with the pressure paddle 524 and the exhaust paddle 522 in the pressure chamber 517 and the exhaust chamber 515, and under the action of centrifugal force, the production stock gathers toward the inner walls of the pressure chamber 517 and the exhaust chamber 515, and as the pressure paddle 524 and the exhaust paddle 522 rotate, the production stock adhering to the inner walls of the pressure chamber 517 and the exhaust chamber 515 increases, so that raw materials on the inner walls of the pressure chamber 517 and the exhaust chamber 515 are not easily removed to be solidified. Therefore, the purpose of setting the blades of the pressure paddle 524 and the exhaust paddle 522 to be in the hook shape and enabling the bending direction to be consistent with the rotation direction is to enable the blades of the pressure paddle 524 and the exhaust paddle 522 to drive the production raw pulp on the inner walls close to the pressure cavity 517 and the exhaust cavity 515 to the rotation center in the rotation process, so that the phenomenon that the more the production raw pulp on the inner walls of the pressure cavity 517 and the exhaust cavity 515 is gathered under the action of centrifugal force, the more the fracture phenomenon is finally caused at one end of the blades far away from the connecting piece due to the increase of resistance. And simultaneously, the solidification phenomenon caused by excessive raw material accumulation on the inner walls of the pressure cavity 517 and the exhaust cavity 515 is avoided, and the pressure cavity 517 and the exhaust cavity 515 have self-cleaning capability.

In this embodiment, in order to improve the automatic cleaning capability of the gas separation device 50, the rotation diameter of the end of the blade of the exhaust paddle 522 near the side wall of the exhaust chamber 515 is adapted to the diameter of the exhaust chamber 515, and the rotation diameter of the end of the blade of the pressure paddle 524 near the pressure chamber 517 is adapted to the diameter of the pressure chamber 517. The purpose of this arrangement is to allow the blades to further carry away the material on the inner walls of the pressure chamber 517 and the exhaust chamber 515 during rotation of the pressure paddle 524 and the exhaust paddle 522, so that the self-cleaning capacity of the pressure chamber 517 and the exhaust chamber 515 is stronger.

The disperser 523 in this embodiment includes a connection shaft and a group of dispersing pieces symmetrically distributed along the axial direction of the connection shaft, and the connection shaft is fixedly sleeved on the rotation shaft 521. It will be appreciated by those skilled in the art that the number of the dispersing tablets may be three or four or more parts which are uniform along the circumferential direction of the connecting shaft, the specific number of the dispersing tablets may be determined according to the flow rate of the injection molding raw slurry entering the dispersing cavity 516, and when the flow rate is large, the number of the dispersing tablets may be appropriately increased, whereas the number of the dispersing tablets may be appropriately decreased; the dispersing pieces and the connecting shaft can be welded and fixed or integrally formed, and in the embodiment, the dispersing pieces and the connecting shaft are preferably integrally formed. The diameter of the end of the dispersion plate adjacent to the side wall of dispersion chamber 516 is adapted to the diameter of dispersion chamber 516. The purpose of this arrangement is to allow the raw material entering the dispersion chamber 516 to be sufficiently dispersed by the disperser 523, so that the gas contained in the raw material is sufficiently separated, thereby ensuring the quality of the gypsum lightweight hollow partition board.

Because the production raw slurry for producing the gypsum light hollow partition plate has the characteristic of quick solidification, after the production raw slurry enters the injection molding cavity 67, the production raw slurry can be quickly solidified, and the solidified gypsum light hollow partition plate can move to one side far away from the molding host 60 under the drive of the soft conveying belt and finally is cut and stored, so that the production continuity is improved, and a set of dies can be used for continuous production, so that the production efficiency is improved.

In this embodiment, the core extracting shafts 66 for extracting core from the gypsum light hollow partition board are arranged in a pair as a group, and the purpose of the arrangement is to enable the surface of the core extracting shaft 66 to realize a self-cleaning function in the core extracting process.

The large-diameter section is used for core pulling of the gypsum light hollow partition board, and the distance between the outer circumferential surfaces of the large-diameter sections of the two core pulling shafts 66 in each group is smaller than 1mm. Because the distance between the outer circumferential surfaces of the large-diameter sections of the two loose-core shafts 66 in each group is smaller than 1mm, when the production raw slurry is attached to the outer circumferential surfaces of the large-diameter sections of the loose-core shafts 66, the production raw slurry attached to the surfaces of each group is carried along by friction force generated in the rotation process between the loose-core shafts 66, so that the cleanliness of the loose-core shafts 66 is ensured. Thus, the condition that the core holes of the gypsum light hollow partition wall board are bigger and bigger due to the long-time operation of the core drawing shaft 66 and the original production slurry is solidified on the surface, and finally the strength of the gypsum light hollow partition wall board is reduced is avoided.
