Description

Technical Field

[0001] This invention relates to the field of hand-made glove mold preparation technology, and in particular to a mixing device for raw materials of nitrile glove mold. Background Technology

[0002] Nitrile gloves are primarily made of nitrile rubber and are essential protective equipment used in scientific research industries such as medical, pharmaceutical, beauty, food processing, chemical, and biological fields. They serve to protect hands and prevent cross-infection. The production process of nitrile gloves mainly involves impregnation with nitrile latex (dipping), molding, vulcanization, surface treatment, and dust-free cleaning. The dipping step involves impregnating the glove mold with nitrile latex before molding. The nitrile glove mold is an essential tool used to assist in the dipping process. In the production of nitrile hand molds, the raw materials are typically mixed to obtain a slurry, followed by shaping, drying, brushing, spraying with hemp, glazing, firing in a kiln, and polishing to obtain the ceramic hand mold. Current technology typically uses unidirectional rotation to mix the raw materials to obtain a slurry, but this mixing method often has some problems.

[0003] 1. Unidirectional stirring makes it difficult to mix raw materials quickly and effectively. In addition, because the stirring paddle in the existing technology is located in the middle, the uniformity of the raw materials in the edge area is low during the stirring process. Furthermore, air bubbles are generated in the mixture during the stirring process. In order to improve uniformity, the stirring time is longer, and the number of air bubbles increases. The presence of air bubbles causes voids in the interior and surface of the mixture after solidification. The presence of voids makes the finished mold porous, resulting in poor strength and poor water absorption.

[0004] 2. The existing inlets are all single, which means that both dry and wet raw materials enter through the same inlet. This can easily cause solid raw materials to adhere to the surface of the inlet, resulting in waste of raw materials and eventually causing blockage of the inlet.

[0005] Therefore, there is an urgent need for a mixing and blending device for nitrile glove mold raw materials to solve the above-mentioned defects. Summary of the Invention

[0006] I. Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: a mixing device for nitrile glove mold raw materials, comprising a shell, a liquid inlet at the upper left end of the shell, a solid inlet at the upper right end of the shell, a mixing cylinder at the lower end of the shell, a vibration component at the bottom of the mixing cylinder, a drive shaft at the middle of the mixing cylinder, puncture-type paddles evenly arranged at the middle of the drive shaft, angled paddles located below the puncture-type paddles and arranged on the drive shaft, and a discharge port at the lower end of the shell.

[0008] The solid feed inlet includes a feed pipe, an air pump, a baffle plate, a vibrating plate, a contact block, a cam, and a drive motor. The feed pipe is mounted on the outer wall of the housing via a bracket. An air pump is installed on the outer wall of the feed pipe, with its inlet extending into the feed pipe. A baffle plate located above the air pump inlet is installed inside the feed pipe to reduce the possibility of solid raw materials flying upwards. The vibrating plate located below the feed pipe outlet is slidably connected to the housing. A contact block is installed on the vibrating plate, and a cam that contacts the contact block is mounted on the output shaft of the drive motor. The drive motor is mounted on the side wall of the housing via a motor housing. The drive motor drives the cam to rotate. According to the cam motion principle, the vibrating plate vibrates at a high frequency. When solid and liquid raw materials are mixed and conveyed, the solid raw materials are easily stuck at the inlet position. Therefore, the separate conveying reduces material waste. Furthermore, the solid feed inlet in this application uses vibration and air blowing, combined with the rotation of the mixing drum, to evenly distribute the solid raw materials inside the mixing drum, improving the degree of uniform conveying.

[0009] The drive shaft includes a rotating shaft, a rotating motor, a support plate, and extrusion balls. The upper end of the rotating shaft is connected to the upper end of the outer shell by a bearing. The rotating shaft is connected to the rotating motor mounted on the outer shell. The middle part of the rotating shaft is connected to the support plate mounted inside the outer shell by a bearing. Extrusion balls are evenly installed on the lower end of the support plate in a ring arrangement.

[0010] The puncture-type paddle includes a connector, a paddle plate, a linkage assembly, an exposed assembly, and a puncture needle. The connector is mounted on a rotating shaft, and the paddle plate is installed at the outer end of the connector. The exposed assembly is symmetrically and slidably arranged inside the paddle plate, and the puncture needle is installed on the exposed assembly. The extrusion ball, the exposed assembly, and the linkage assembly inside the connector cooperate to compress each other. During the rotation of the puncture-type paddle, as the paddle plate rotates as a whole, the linkage assembly and the extrusion ball intermittently compress each other. At the same time, the linkage assembly and the exposed assembly compress each other synchronously, thereby squeezing out the puncture needle and extending it into the mixed paddle. When it encounters an air bubble, it can be punctured instantly.

[0011] As a preferred embodiment of the present invention, the upper end of the liquid feed inlet is a flared structure, which facilitates the entry of liquid raw materials. An opening and closing door is provided on the left end of the outer shell. The opening and closing door is opened periodically to perform routine inspections of the interior of the present invention.

[0012] As a preferred technical solution of the present invention, the inclined surface of the vibrating plate is gradually inclined downward from right to left, which is used for inclined conveying of solid raw materials. The lower end face of the vibrating plate is provided with a piercing needle. The up and down vibration of the vibrating plate drives the piercing needle to vibrate up and down, thereby piercing the edge of the rotating mixing drum. When encountering air bubbles, they can be pierced in time. The output port of the feed pipe extends into the interior of the outer shell.

[0013] As a preferred embodiment of the present invention, the stirring cylinder includes a cylinder body, an annular electric slider, and an inclined paddle. The cylinder body is horizontally rotatably disposed inside the outer shell, and the annular electric slider is connected between the outer shell and the cylinder body. Inclined paddles are uniformly installed along the circumference of the inner wall of the cylinder body.

[0014] As a preferred embodiment of the present invention, the vibration assembly includes a vibration ring, a contact element, an extrusion cylinder, and a pusher element. An annular groove is provided at the bottom of the cylinder, and a vibration ring (the vibration direction of the vibration ring is up and down) is slidably arranged in the annular groove. Contact elements are evenly arranged along the circumference of the lower end of the vibration ring. The contact elements pass through the bottom of the cylinder and intermittently contact the extrusion cylinder. The extrusion cylinder is installed at the bottom of the outer shell, and pusher elements are evenly installed at the upper end of the vibration ring.

[0015] As a preferred embodiment of the present invention, the pushing component includes a sliding rod and a pushing plate. The lower end of the sliding rod is slidably disposed on the vibrating ring, and the upper end of the sliding rod is symmetrically provided with right-angle grooves. The right-angle grooves and the pushing plate are connected by a pin. The lower end face of the horizontal pushing plate is in contact with the lower end face of the right-angle groove. The specific lifting and lowering form of the pushing component is as follows: When rising, due to the limitation of the lower end face of the right-angle groove, the sliding rod and the pushing plate maintain the current state (T-shaped) and rise. The T-shaped structure can also help the raw material rise over a larger area. When falling, due to the obstruction of the raw material and the lack of structural limitation above the pushing plate, the pushing plate falls in a V-shaped state. The V-shaped state reduces the area where the raw material is forcibly pressed down.

[0016] As a preferred embodiment of the present invention, the linkage component includes an extrusion column, a built-in spring, and an extrusion block. The extrusion column is slidably disposed in the L-shaped cavity of the connector. The built-in spring is connected between the extrusion column and the L-shaped cavity and plays a resetting role. The extrusion block, which cooperates with the extrusion column in extrusion, is slidably disposed in the L-shaped cavity.

[0017] As a preferred embodiment of the present invention, the exposed component includes a horizontal plate, a pressure block, a connecting spring, and an extension rod. The horizontal plate is slidably disposed in a sliding groove opened inside the paddle plate. The pressure block and the extrusion block disposed on the horizontal plate are connected by a compression fit. A connecting spring is connected between the middle of the horizontal plate and the paddle plate, and the connecting spring plays a role in resetting. An extension rod is uniformly installed at the end of the horizontal plate away from the connecting spring, and a puncture needle is uniformly installed at the outer end of the extension rod.

[0018] As a preferred embodiment of the present invention, the angled paddle body includes a connecting column, a stirring paddle, a hemisphere, and a connecting plate. One end of the connecting column is connected to the rotating shaft by a ball hinge. The connecting column is arranged in a ring. The other end of the connecting column is equipped with a stirring paddle. The rotating shaft is connected to the connecting plate installed on the stirring cylinder by a bearing. Hemispheres are evenly installed on the connecting plate, and the hemispheres and the connecting plate form an integrally formed extrusion. The connecting column rests on the upper surface of the extrusion.

[0019] As a preferred embodiment of the present invention, the discharge port includes a sealing plate, a lifting cylinder, an output pump, a concentrator frame, and a stabilizing base. A discharge hole is provided in the middle of the lower end of the mixing cylinder. The discharge hole and the sealing plate are sealed together. The sealing plate is connected to the top end of the lifting cylinder. The lifting cylinder is installed at the lower end of the outer shell through a cylinder seat. A corresponding hole corresponding to the position of the discharge hole is opened at the lower end of the outer shell. Discharge chambers are symmetrically opened at both ends of the corresponding hole. A concentrator frame is connected to the lower end of the discharge chamber. The middle of the concentrator frame is connected to the output pump. The output pump is installed on the side wall of the cylinder seat. A connecting pipe is connected to the lower end of the concentrator frame. A stabilizing base is installed at the upper end of the sealing plate.

[0020] As a preferred embodiment of the present invention, the stabilizing base is provided with an inlet groove, and an ejector plate is slidably arranged inside the inlet groove. A return spring is connected between the ejector plate and the lower end of the inlet groove. Rollable connecting beads are evenly arranged on the upper end of the ejector plate. The stabilizing base is provided to ensure the stability of the lower end of the rotating shaft when it rotates. When the sealing plate closes the discharge hole, the lower end of the rotating shaft is inserted into the inlet groove to achieve stable rotation. During rotation, the connecting beads reduce the resistance. When the sealing plate descends, the rotating shaft also stops rotating. To prevent the mixed slurry from entering the inlet groove, the ejector plate is pushed upward under the action of the return spring to eject the mixed slurry from the inlet groove.

[0021] As a preferred embodiment of the present invention, a drag-reducing component is provided between the bottom of the outer shell and the bottom of the cylinder. The drag-reducing component includes a ball bearing, a connecting ring, and a drag-reducing bead. Rollable balls are evenly distributed on the upper surface of the bottom of the outer shell, and the balls are in contact with the lower surface of the cylinder. A connecting ring is installed at the bottom of the outer shell and is embedded in a rotating groove opened in the cylinder. Rollable drag-reducing beads are provided on the side wall of the connecting ring and fit against the inner side wall of the rotating groove. The ball bearing and the drag-reducing bead are provided to reduce the friction between the cylinder and the bottom of the outer shell when the cylinder rotates.

[0022] II. Beneficial Effects

[0023] 1. The nitrile glove mold raw material mixing device of the present invention addresses the presence of air bubbles (most of which are present in the upper half of the mixed slurry). On the one hand, it improves the mixing efficiency and shortens the mixing time through multi-directional mixing (the shortened time reduces the generation of air bubbles). On the other hand, it reduces the amount of air bubbles by using a telescopic puncturing needle (rotating horizontally) and the up-and-down vibration of the puncturing needle (puncturing the air bubbles on the surface of the mixed slurry). Through the dual methods of shortening the time and forcibly puncturing the air bubbles, the amount of air bubbles is reduced, and the formation of voids is greatly reduced.

[0024] 2. The nitrile glove mold raw material mixing device of the present invention adopts a differentiated conveying method for the input of raw materials, so as to separate and convey dry and wet raw materials, avoid the situation where solid raw materials adhere to the input port due to mutual interference, and also avoid the situation where the input port is blocked.

[0025] 3. The nitrile glove mold raw material mixing device of the present invention adopts a multi-directional mixing method (horizontal circumferential mixing of puncture-type paddle, irregular mixing of angled paddle, and inclined structure mixing of inclined paddle) and internal and external reverse mixing (the driving shaft is opposite to the direction of the mixing cylinder), combined with the upward pushing at the bottom, which improves the mixing effect between the raw materials of each layer and improves the uniformity.

[0035] Embodiments of the present invention will now be described with reference to the accompanying drawings. In this process, to ensure clarity and convenience, we may exaggerate the width of lines or the size of constituent elements in the drawings.

[0036] Furthermore, the terms used below are defined based on the functionality of this invention and may vary depending on the user's, operator's, or conventions. Therefore, these terms are defined based on the entire contents of this specification.

[0037] like Figures 1 to 8 As shown, a mixing device for nitrile glove mold raw materials includes a shell 1, a liquid inlet 2 at the upper left end of the shell 1, a solid inlet 3 at the upper right end of the shell 1, a mixing drum 4 at the lower end of the shell 1, a vibration component 5 at the bottom of the mixing drum 4, a drive shaft 6 in the middle of the mixing drum 4, puncture-type paddles 7 evenly arranged in the middle of the drive shaft 6, an angled paddle 8 located below the puncture-type paddles 7 on the drive shaft 6, and a discharge port 9 at the lower end of the shell 1.

[0038] The solid feed inlet 3 includes a feed pipe 31, an air pump 32, a baffle plate 33, a vibrating plate 34, a contact block 35, a cam 36, and a drive motor 37. The feed pipe 31 is mounted on the outer wall of the outer casing 1 via a bracket. The air pump 32 is mounted on the outer wall of the feed pipe 31, and the inlet of the air pump 32 extends into the feed pipe 31. The baffle plate 33, located above the inlet of the air pump 32, is installed inside the feed pipe 31. The baffle plate 33 is designed to reduce the possibility of solid raw materials flying upwards. The vibrating plate 34, located below the outlet of the feed pipe 31, is slidably connected to the outer casing 1. A contact block 35 is mounted on the vibrating plate 34. The contact block 35 and the cam 36 that contacts the contact block 35 are mounted on the output shaft of the drive motor 37. The drive motor 37 is mounted on the side wall of the outer casing 1 through the motor housing. The drive motor 37 drives the cam 36 to rotate. According to the cam motion principle, the vibrating plate 34 vibrates at a high frequency. When solid and liquid raw materials are mixed and conveyed, the solid raw materials are easily stuck at the inlet position. Therefore, the separation conveying reduces the waste of raw materials. In addition, the solid feed inlet 3 in this application adopts the method of vibration and air blowing, combined with the rotation of the mixing drum 4, so that the solid raw materials fall evenly into the mixing drum 4, which improves the degree of uniform conveying.

[0039] The drive shaft 6 includes a rotating shaft 61, a rotating motor 62, a support plate 63, and extrusion balls 64. The upper end of the rotating shaft 61 is connected to the upper end of the outer shell 1 by a bearing. The rotating shaft 61 is connected to the rotating motor 62 installed on the outer shell 1. The middle part of the rotating shaft 61 is connected to the support plate 63 installed inside the outer shell 1 by a bearing. Extrusion balls 64 are evenly installed on the lower end of the support plate 63 in a ring arrangement.

[0040] The puncture-type paddle 7 includes a connector 71, a paddle plate 72, a linkage assembly 73, an exposed assembly 74, and a puncture needle 75. The connector 71 is mounted on a rotating shaft 61, and the paddle plate 72 is mounted on the outer end of the connector 71. The exposed assembly 74 is symmetrically and slidably arranged inside the paddle plate 72, and the puncture needle 75 is mounted on the exposed assembly 74. The extrusion ball 64, the exposed assembly 74, and the linkage assembly 73 inside the connector 71 cooperate to compress each other. During the rotation of the puncture-type paddle 7, as the paddle plate 72 rotates as a whole, the linkage assembly 73 and the extrusion ball 64 intermittently compress each other. At the same time as the compression, the linkage assembly 73 and the exposed assembly 74 compress each other synchronously, thereby squeezing out the puncture needle 75 and extending it into the mixed paddle. When it encounters an air bubble, it can be punctured instantly.

[0041] Specifically, solid and liquid raw materials are transported separately. Liquid raw materials are input through the liquid inlet 2, and solid raw materials are input through the feed pipe 31. During the input process, the solid raw materials are transported downward by the air blowing of the air pump 32 and the vibration of the vibrating plate 34. At the same time, since the mixing drum 4 is in a horizontal rotating state, the falling solid raw materials are evenly dispersed inside the mixing drum 4. After the raw materials are transported, the rotating shaft 61, the puncturing paddle 7, and the angled paddle 8 are driven to rotate synchronously by the rotating motor 62 (when the puncturing paddle 7 rotates, the puncturing needle 75 is in a cyclical extension and retraction, thereby reducing the presence of air bubbles; when the angled paddle 8 rotates, it is adjusted up and down). Combined with the reverse rotation of the mixing drum 4, the mixed raw materials are mixed and stirred in multiple areas and directions, while reducing the content of air bubbles in the mixed slurry. The setting of the vibration component 5 can push the raw materials at the bottom upward in a cyclical manner, avoiding the sinking situation. Compared with the existing single-direction stirring, the mixing rate is improved and the air bubble presence rate is reduced.

[0042] In another embodiment of the present invention, the upper end of the liquid feed inlet 2 is a flared structure to facilitate the entry of liquid raw materials, and the left end of the outer shell 1 is provided with an opening and closing door, which is opened periodically to perform routine inspections of the interior of the present application.

[0043] Furthermore, the inclined surface of the vibrating plate 34 gradually slopes downward from right to left, which is used for the inclined conveying of solid raw materials. The lower end face of the vibrating plate 34 is provided with a piercing needle. The up and down vibration of the vibrating plate 34 drives the piercing needle to vibrate up and down, thereby piercing the rotating mixing drum 4 at the edge. When encountering air bubbles, they can be pierced in time. The output port of the feed pipe 31 extends into the interior of the outer shell 1.

[0044] Furthermore, the stirring drum 4 includes a drum body 41, an annular electric slider 42, and an inclined paddle 43. The drum body 41 is horizontally rotatably disposed inside the outer shell 1. The annular electric slider 42 is connected between the outer shell 1 and the drum body 41. Inclined paddles 43 are uniformly installed along the circumference of the inner wall of the drum body 41.

[0045] Specifically, the cylinder 41 is rotated by the annular electric slider 42 (the rotation direction of the cylinder 41 is opposite to the rotation direction of the rotating shaft 61), and the tilting paddle 43 rotates synchronously.

[0046] Furthermore, the vibration assembly 5 includes a vibration ring 51, a contact member 52, a pressing cylinder 53, and a pusher 54. An annular groove is provided at the bottom of the cylinder 41, and the vibration ring 51 (the vibration direction of the vibration ring 51 is up and down) is slidably arranged in the annular groove. The contact member 52 is evenly arranged along the circumference of the lower end of the vibration ring 51. After passing through the bottom of the cylinder 41, the contact member 52 intermittently contacts the pressing cylinder 53. The pressing cylinder 53 is installed at the bottom of the outer shell 1, and the pusher 54 is evenly installed at the upper end of the vibration ring 51.

[0047] Furthermore, the pushing member 54 includes a sliding rod 541 and a pushing plate 542. The lower end of the sliding rod 541 is slidably mounted on the vibration ring 51. The upper end of the sliding rod 541 is symmetrically provided with right-angle grooves. The right-angle grooves and the pushing plate 542 are connected by a pin. The lower end face of the horizontal pushing plate 542 is in contact with the lower end face of the right-angle groove. The specific lifting and lowering form of the pushing member 54 is as follows: When rising, due to the limitation of the lower end face of the right-angle groove, the sliding rod 541 and the pushing plate 542 maintain the current state (T-shaped) and rise. The T-shaped structure can also help the raw material rise over a larger area. When falling, due to the obstruction of the raw material and the lack of structural limitation above the pushing plate 542, the pushing plate 542 falls in a V-shaped state. The V-shaped state reduces the area where the raw material is forcibly pressed down.

[0048] Specifically, when the cylinder 41 and the vibrating ring 51 rotate horizontally in sync, the contact member 52 and the extrusion cylinder 53 intermittently press against each other. When they come into contact, they push the pusher 54 upward, thereby pushing the bottom layer of mixed slurry upward. After they separate, the pusher 54 descends and resets, and pushes upward in a cyclical manner, thereby agitating the bottom layer of raw materials and avoiding uneven mixing caused by long-term raw material deposition.

[0049] Furthermore, the linkage component 73 includes a pressing column 731, a built-in spring 732, and a pressing block 733. The pressing column 731 is slidably disposed in the L-shaped cavity of the connector 71. The built-in spring 732 is connected between the pressing column 731 and the L-shaped cavity. The built-in spring 732 plays a reset role. The pressing block 733, which cooperates with the pressing column 731, is slidably disposed in the L-shaped cavity.

[0050] Furthermore, the exposed component 74 includes a horizontal plate 741, a pressure block 742, a connecting spring 743, and an extension rod 744. The horizontal plate 741 is slidably disposed in a sliding groove opened inside the paddle plate 72. The pressure block 742 and the extrusion block 733 disposed on the horizontal plate 741 are connected by a compression fit. A connecting spring 743 is connected between the middle of the horizontal plate 741 and the paddle plate 72. The connecting spring 743 plays a resetting role. Extension rods 744 are evenly installed at the end of the horizontal plate 741 away from the connecting spring 743. Puncture needles 75 are evenly installed at the outer end of the extension rods 744.

[0051] Specifically, as the annularly arranged slurry plate 72 rotates as a whole, the extrusion column 731 and the extrusion ball 64 in the linkage assembly 73 are intermittently extruded. At the same time, the extrusion column 731 descends, thereby extruding the extrusion block 733 outward. Under the extrusion of the extrusion block 733 and the pressure block 742, the horizontal plate 741 arranged vertically moves in opposite directions. At this time, the puncturing needle 75 extends outward and penetrates into the mixed slurry. When it encounters an air bubble, it can puncture it instantly.

[0052] Furthermore, the angled paddle 8 includes a connecting column 81, a stirring paddle 82, a hemisphere 83, and a connecting plate 84. One end of the connecting column 81 is connected to the rotating shaft 61 by a ball hinge. The connecting column 81 is arranged in a ring. The stirring paddle 82 is installed at the other end of the connecting column 81. The rotating shaft 61 is connected to the connecting plate 84 installed on the stirring cylinder 4 by a bearing. The hemispheres 83 are evenly installed on the connecting plate 84, and the hemispheres 83 and the connecting plate 84 form an integrally formed extrusion. The connecting column 81 rests on the upper surface of the extrusion.

[0053] Specifically, during the rotation of the annularly arranged stirring paddle 82, the connecting column 81 rotates along with it, thus always keeping in contact with the upper surface of the extruder. Since the extruder is composed of a hemisphere 83 and a connecting plate 84, its upper surface is uneven. When the connecting column 81 makes overlapping contact, it adjusts the angle. Furthermore, since the connecting column 81 is connected to the rotating shaft 61 by a ball hinge, the stirring paddle 82 adjusts the angle irregularly, thereby disrupting the mixture and improving the uniformity of mixing.

[0054] Furthermore, the discharge port 9 includes a sealing plate 91, a lifting cylinder 92, an output pump 93, a concentrating frame 94, and a stabilizing base 95. A discharge hole is provided in the lower middle part of the mixing drum 4. The discharge hole and the sealing plate 91 are sealed together. The sealing plate 91 is connected to the top end of the lifting cylinder 92. The lifting cylinder 92 is mounted on the lower end of the outer shell 1 via a cylinder seat. A corresponding hole, corresponding to the position of the discharge hole, is opened at the lower end of the outer shell 1. Discharge chambers are symmetrically opened at both ends of the corresponding hole. The lower end of the discharge chamber is connected to the concentrating frame 94. The middle part of the concentrating frame 94 is connected to the output pump 93. The output pump 93 is mounted on the side wall of the cylinder seat. The lower end of the concentrating frame 94 is connected to a connecting pipe. The upper end of the sealing plate 91 is equipped with the stabilizing base 95. The stabilizing base 95 has an inlet groove, and an ejector plate 96 is slidably mounted inside the inlet groove. A return spring 97 is connected between the ejector plate 96 and the lower end of the inlet groove. Rollable connecting beads 98 are evenly arranged on the upper end of the ejector plate 96. The stabilizing base 95 is designed to ensure the stability of the lower end of the rotating shaft 61 when it rotates. When the sealing plate 91 closes the discharge hole, the lower end of the rotating shaft 61 is inserted into the inlet groove for stable rotation. During rotation, the connecting beads 98 reduce the resistance. When the sealing plate 91 descends, the rotating shaft 61 also stops rotating. To prevent the mixed slurry from entering the inlet groove, the ejector plate 96 is pushed upward under the action of the return spring 97, thereby ejecting the mixed slurry from the inlet groove.

[0055] Specifically, during the mixing process, the sealing plate 91, which rises to the highest position, seals the outlet hole, thereby achieving the purpose of sealing. After mixing, the lifting cylinder 92 drives the sealing plate 91 to the lowest position. At this time, the outlet chamber is connected to the inside of the mixing drum 4. Then, the mixed slurry passes through the outlet chamber and is output from the connecting pipe under the operation of the output pump 93.

[0056] Furthermore, a drag-reducing component 10 is provided between the bottom of the outer shell 1 and the bottom of the cylinder 41. The drag-reducing component 10 includes a ball bearing 101, a connecting ring 102, and a drag-reducing bead 103. Rollable balls 101 are evenly distributed on the upper surface of the bottom of the outer shell 1. The balls 101 are in contact with the lower surface of the cylinder 41. A connecting ring 102 is installed at the bottom of the outer shell 1. The connecting ring 102 is embedded in a rotating groove opened in the cylinder 41. Rollable drag-reducing beads 103 are provided on the side wall of the connecting ring 102. The drag-reducing beads 103 are in contact with the inner side wall of the rotating groove. The balls 101 and the drag-reducing beads 103 are provided to reduce the friction between the cylinder 41 and the bottom of the outer shell 1 when the cylinder 41 rotates.

[0057] Work process:

[0058] Step 1: Input liquid raw materials from liquid inlet 2 and solid raw materials from feed pipe 31. During the solid raw material input process, since the stirring drum 4 is in a horizontal rotating state, the falling solid raw materials are evenly dispersed inside the stirring drum 4. The raw material delivery is completed.

[0059] Step 2: The rotating shaft 61, the puncturing paddle 7, and the angled paddle 8 are driven to rotate synchronously by the rotating motor 62, and then the mixing drum 4 rotates in the opposite direction to mix the raw materials in multiple areas and directions. At the same time, the air bubbles in the mixture are punctured in different areas. Meanwhile, in order to avoid a large amount of material settling to the bottom, the vibration component 5 pushes the raw materials at the bottom upward in a circulating manner.

[0060] Step 3: After mixing, the sealing plate 91 is lowered to the lowest position by the lifting cylinder 92. At this time, the discharge chamber is connected to the inside of the mixing cylinder 4. Then the mixed slurry passes through the discharge chamber and is output from the connecting pipe under the operation of the output pump 93.

[0061] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
