Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building material production, in particular to a magnesium cement composite production quantitative feeding and mixing device. BACKGROUND

[0002] Magnesium cement is widely used in fireproof board, light partition wall and decorative materials due to its excellent fireproof, heat insulation, light weight and environmental protection performance. The material takes magnesium oxide as the main cement component, and generates a hardening body structure with basic magnesium chloride as the main product through chemical reaction with magnesium chloride solution.

[0003] In the production process of magnesium cement, the mixing device as a key automatic production equipment undertakes the functions of accurately controlling the feeding ratio and sequence of multiple raw materials and realizing efficient and uniform mixing of the raw materials, so as to ensure that the components are fully combined and uniformly distributed.

[0004] However, in the actual mixing process, due to the limitation of the sweeping range of the stirring paddle, especially in the case of small paddle size or eccentric installation position, the material near the inner wall and corner area of the stirring barrel flows slowly, forming a mixing dead angle. In such areas, magnesium oxide powder and fillers and other raw materials are prone to accumulate, leading to uneven mixing in the local area, which in turn affects the full chemical reaction and reduces the uniformity and stability of the material performance. The fixed large-radius paddle needs to overcome the static friction of all materials at the starting moment, which has a large starting load and is prone to cause motor overload.

[0015] Compared with the prior art, the present application has the following advantages:

[0016] 1. This invention utilizes the centrifugal force generated by the rotation of the stirring blades to cause the extension plate to expand to both sides. The expanded end can reach the material area near the inner wall of the mixing chamber, effectively eliminating the dead corners in the side wall mixing process commonly seen in traditional stirring. This allows components such as magnesium oxide, magnesium chloride solution, and fillers to be fully mixed, thereby significantly improving the mixing uniformity. At the same time, the outer end of the extended plate has a higher linear velocity after expansion, generating stronger shear force and turbulence effect, which helps to enhance the dispersion ability and effectively break up agglomerates in the material. In addition, the bottom end of the locking component engages with the square hole on the surface of the sliding component to prevent the extension plate from shrinking due to force during operation, avoiding sudden changes in the stirring radius, improving the rigidity of the stirring structure, and enhancing its stability and load-bearing capacity under high load conditions.

[0017] 2. This invention utilizes the interlocking action between the upper and lower clamping teeth. When the torque generated by the rotation of the stirring blades exceeds a set threshold, the upper and lower clamping teeth automatically slip, cutting off the power transmission path and allowing the servo motor to idle, thus reducing the load to zero. This effectively prevents damage to the transmission system due to overload and significantly extends the service life of the equipment. Furthermore, by adjusting the upward movement of the pressure plate to compress the pressure spring, the interlocking strength between the upper and lower clamping teeth can be flexibly adjusted according to the viscosity characteristics of different materials, thereby achieving dynamic protection under different load conditions and improving the adaptability and safety of equipment operation.

[0018] 3. This invention generates periodic excitation force through the rotation of the eccentric block, causing the mixing tank to vibrate slightly, thereby breaking the adhesion between the material and the tank wall, effectively preventing the slurry from sticking to the wall. At the same time, this vibration can enhance the fluidity of the material, accelerate the speed at which the material enters the main mixing zone, improve mixing efficiency, shorten mixing time, and further improve mixing uniformity, thereby increasing the consistency of product quality.

[0019] 4. Before the material is fed into the rotating box, the weight of the material can be set by moving the counterweight block. The weight of the material can be preset, which can significantly improve the feeding accuracy and enhance the stability of product quality. This structure can not only effectively prevent the overfeeding of materials and avoid the risk of raw material waste and reaction runaway, but also reduce the production loss caused by feeding errors.

Based on the embodiments in the application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the application.

[0029] A quantitative feeding mixing device for magnesium cement composite production comprises a support frame 1, a stirring barrel 11 slidably connected to the upper surface of the support frame 1, wherein the stirring barrel 11 is used for mixing materials, a rotating disc 12 rotatably connected to the upper surface of the stirring barrel 11, a first fixing frame 13 fixedly connected to the upper surface of the rotating disc 12, a servo motor 14 detachably connected to the middle part of the first fixing frame 13, a stirring blade 15 rotatably connected to the inner side of the stirring barrel 11, wherein the top end of the stirring blade 15 is fixedly connected to the inner side of the rotating disc 12, and the stirring blade 15 is used for stirring materials, and the output shaft of the servo motor 14 is in clamping fit with the top end of the stirring blade 15, and the servo motor 14 is used for rotating the stirring blade 15.

[0030] When the raw materials of the magnesium cement are needed to be mixed, the raw materials are first put into the stirring barrel 11, and the servo motor 14 is started. When the output shaft of the servo motor 14 rotates, the stirring blade 15 rotates synchronously, and the stirring blade 15 can mix the raw materials in the stirring barrel 11.

[0031] As described in the background, in the actual mixing process, due to the limitation of the sweeping range of the stirring paddle, especially in the case of small paddle size or eccentric installation position, the material flow in the area near the inner wall and the corner of the stirring barrel 11 is slow, forming a mixing dead angle. In this area, the raw materials such as magnesium oxide powder and fillers are easily accumulated, which leads to uneven mixing in the local area, and further affects the full chemical reaction, reduces the uniformity and stability of the material performance, and the fixed large radius paddle needs to overcome the static friction of all materials at the starting moment, which causes large starting load and easy motor overload.

[0032] Reference is made to the accompanying drawings Figures 1-3 To solve the problem of the limitation of the sweeping range of the stirring paddle, the embodiment adopts the following technical scheme: the inner side of the stirring blade 15 is symmetrically and slidably connected with an extension plate 24, the stirring blade 15 is used to drive the extension plate 24 to slide through the centrifugal force, the extension plate 24 is used to increase the stirring area of the stirring blade 15, the upper surfaces of the extension plate 24 are symmetrically and fixedly connected with sliding members 23 on the side close to each other, the upper surfaces of the sliding members 23 are slidably penetrated through the upper surface of the rotating disc 12, the outer surface of the top of the stirring blade 15 is slidably connected with a sliding disc 211, the top ends of the sliding members 23 are rotatably connected with connecting rods 21, the top ends of the connecting rods 21 are rotatably connected with the two sides of the sliding disc 211, the sliding members 23 are used to drive the sliding disc 211 to move downward through the connecting rods 21 when the sliding members 23 move, the outer surface of the top of the stirring blade 15 is fixedly sleeved with a compression spring 22, the top end of the compression spring 22 is fixedly connected with the lower surface of the sliding disc 211, the compression spring 22 is used to drive the sliding disc 211 to reset, the top of the stirring blade 15 is fixedly connected with a stirring rod 2, the output shaft of the servo motor 14 is clamped and matched with the upper surface of the stirring rod 2, and the servo motor 14 is used to drive the stirring rod 2 to rotate.

[0033] When the materials are mixed, the servo motor 14 drives the stirring rod 2 to rotate through the output shaft, and then drives the stirring blade 15 to rotate synchronously. The stirring blade 15 can not only mix the materials in the stirring barrel 11 during the rotation, but also slide and expand the extension plate 24 symmetrically and slidably connected to the inner side of the stirring blade 15 to the side away from each other due to the centrifugal force. The expansion of the extension plate 24 can effectively increase the overall stirring area of the stirring blade 15.

[0034] During the sliding of the extension plate 24, the upper surfaces of the sides close to each other of the extension plate 24 drive the connecting rods 21 to move through the sliding pieces 23, the top ends of the sliding pieces 23 are rotationally connected to the two sides of the sliding disc 211 through the connecting rods 21, with the unfolding of the extension plate 24, the sliding pieces 23 are synchronously moved outward, and the sliding disc 211 is pulled downward through the connecting rods 21, and the sliding disc 211 is pressed and compressed when moving.

[0035] When the stirring blades 15 drive the unfolded extension plate 24 to rotate, the end part of the unfolded extension plate 24 can reach the material area near the inner wall of the mixing bin, effectively eliminating the common edge wall mixing dead angle in the traditional stirring process, so that the magnesium oxide, magnesium chloride solution and filler and other components are fully mixed, thereby significantly improving the mixing uniformity, and the linear speed of the outer end of the unfolded extension plate 24 is higher, stronger shear force and turbulence effect are generated, which helps to enhance the dispersion capacity and effectively break up the agglomerates in the material.

[0036] The upper surfaces of the rotating disc 12 are fixedly connected to limiting frames 251 in a symmetrical manner, the sides close to each other of the limiting frames 251 are slidably connected to the clamping pieces 25, the bottom ends of the clamping pieces 25 close to each other are in a symmetrical inclined shape, the sides away from each other of the sliding pieces 23 are in extrusion fit with the inclined surfaces of the bottom ends of the clamping pieces 25, the sliding pieces 23 are used for driving the clamping pieces 25 to move upward, the sides away from each other of the sliding pieces 23 are all provided with square holes, the bottom ends of the clamping pieces 25 are in clamping fit with the square holes of the sliding pieces 23, and the clamping pieces 25 are used for limiting the sliding pieces 23.

[0037] When the sliding pieces 23 slide to the two sides under the driving of the extension plate 24, the outer edges of the sliding pieces 23 are in contact with and apply pressure to the inclined surfaces of the clamping pieces 25, so as to drive the clamping pieces 25 to move upward along the sliding direction, with the continuous outward movement of the sliding pieces 23, the contact between the sliding pieces 23 and the inclined surfaces of the bottom ends of the clamping pieces 25 is gradually separated, at this time, the clamping pieces 25 are reset downward under the action of gravity, and the bottom ends of the clamping pieces 25 are clamped in the direction grooves of the sliding pieces 23 when the clamping pieces 25 move, so as to realize clamping fit, thereby preventing the extension plate 24 from shrinking due to stress during operation, avoiding the sudden change of the stirring radius, improving the rigidity of the stirring structure, and enhancing the stability and bearing capacity of the stirring structure under high load working conditions.

[0038] The inner sides of the limiting frames 251 are slidably connected to sliding blocks 26, the sides close to each other of the sliding blocks 26 are in extrusion fit with the outer surfaces of the clamping pieces 25, the sliding blocks 26 are used for driving the clamping pieces 25 to move upward, the outer surfaces of the middle parts of the limiting frames 251 are fixedly sleeved with reset springs 27, the sides close to each other of the reset springs 27 are all fixedly connected to the surfaces of the sliding blocks 26, and the reset springs 27 are used for driving the sliding blocks 26 to reset and move.

[0039] When the stirring blade 15 rotates the rotating disc 12, the rotating disc 12 rotates the sliding block 26 synchronously through the limiting frame 251, under the action of centrifugal force, the sliding block 26 moves to the side away from each other, and the outer surface of the clamping part 25 is out of contact, at the same time, the reset spring 27 is extruded to the compressed state.

[0040] When the stirring process is over, the stirring blade 15 stops rotating, the reset spring 27 in the compressed state pushes the sliding block 26 to move to the direction of approaching each other, during the movement of the sliding block 26, the inner surface thereof recontacts and exerts pressure on the outer surface of the clamping part 25, so as to make the clamping part 25 move upward along the sliding direction.

[0041] With the upward movement of the clamping part 25, the bottom end thereof is out of the clamping state with the square hole on the sliding part 23, at this time, the compression spring 22 in the compressed state drives the sliding disc 211 to move upward to reset, the sliding disc 211 exerts pulling force on the sliding part 23 through the connecting rod 21, drives the extension plate 24 to move to the side approaching each other, so as to make the extension plate 24 retract to the inner side area of the stirring blade 15 again, and the automatic recovery action of the extension plate 24 is completed.

[0042] When the stirring blade 15 is stuck by the caked material during the mixing of the material, the servo motor 14 still forcibly rotates, so as to easily cause the servo motor 14 to burn out.

[0043] Reference is made to the accompanying drawings Figure 5 In order to solve the problem that the stirring blade 15 is stuck by the caked material and easily causes the servo motor 14 to burn out, the embodiment adopts the following technical scheme: the output shaft of the servo motor 14 is fixedly connected with an upper clamping tooth 3, the servo motor 14 is used for driving the upper clamping tooth 3 to rotate, the outer surface of the top of the stirring rod 2 is slidably connected with a lower clamping tooth 31, the lower surface of the upper clamping tooth 3 is clamped and matched with the upper surface of the lower clamping tooth 31, the upper clamping tooth 3 is used for driving the lower clamping tooth 31 to rotate, the outer surfaces between the two sides of the bottom of the stirring rod 2 are slidably connected with a pressing plate 34, the outer surface of the stirring rod 2 is sleeved with a pressure spring 32, the top end of the pressure spring 32 is fixedly connected to the lower surface of the lower clamping tooth 31, the bottom end of the pressure spring 32 is fixedly connected to the upper surface of the pressing plate 34, and the pressure spring 32 is used for exerting pushing force on the lower clamping tooth 31.

[0044] The outer surface of the bottom of the stirring rod 2 is fixedly sleeved with a first screw rod 33, the inside of the pressing plate 34 is threadedly connected with the outer surface of the first screw rod 33, and the first screw rod 33 is used for driving the pressing plate 34 to move up and down, the outer surface of the bottom end of the stirring rod 2 is rotatably connected with a rotating ring 35, the upper surface of the rotating ring 35 is fixedly connected to the bottom end of the first screw rod 33, and the rotating ring 35 is used for driving the first screw rod 33 to rotate.

[0045] When the servo motor 14 starts and drives the upper clamping tooth 3 to rotate, the upper clamping tooth 3 transmits power to the lower clamping tooth 31 through the clamping effect of the lower clamping tooth 31, and drives the stirring rod 2 to rotate synchronously, thereby driving the stirring blade 15 to mix the material.

[0046] At this time, the upper clamping tooth 3 continues to rotate under the drive of the servo motor 14, and exerts downward pressure on the lower clamping tooth 31 below, forcing the lower clamping tooth 31 to move downward against the elastic force of the pressure spring 32, causing the upper clamping tooth 3 and the lower clamping tooth 31 to disengage from the clamping state, causing the servo motor 14 to idle, the power transmission path is cut off, the load is zero, effectively preventing the transmission system from being damaged due to overload, significantly improving the reliability and service life of the equipment operation.

[0047] When it is necessary to adjust the transmission torque between the upper clamping tooth 3 and the lower clamping tooth 31, the operator can manually rotate the rotating ring 35, which drives the first screw 33 to rotate synchronously, thereby driving the pressing plate 34 to move axially along the stirring rod 2, the bottom end of the pressure spring 32 is driven by the pressing plate 34 to move upward, compressing the pressure spring 32 and increasing the downward thrust of the pressure spring 32 on the lower clamping tooth 31, thereby increasing the clamping strength between the upper clamping tooth 3 and the lower clamping tooth 31. According to the viscosity characteristics of different materials, the clamping strength between the upper clamping tooth 3 and the lower clamping tooth 31 can be flexibly adjusted, so as to realize dynamic protection under different load conditions and improve the adaptability and safety of the equipment operation.

[0048] However, due to the strong viscosity of the magnesium cement slurry, it is easy to adhere to the inner wall and bottom of the stirring barrel 11, causing difficulty in cleaning and affecting the continuity of mixing.

[0049] Reference is made to the accompanying drawings Figure 1 To solve the problem that the material is easily adsorbed on the inner wall and bottom of the stirring barrel 11, the following technical scheme is adopted in the embodiment: the two sides of the first fixed frame 13 are symmetrically connected with eccentric blocks 42, the eccentric blocks 42 are used to drive the stirring barrel 11 to vibrate, one end of each eccentric block 42 is fixedly connected with a gear 41, the gear 41 is used to drive the eccentric block 42 to rotate, the upper surface of the rotating disc 12 is fixedly connected with a gear ring 4, the upper surface of the gear ring 4 is in meshing cooperation with the outer surface of the gear 41, the outer surfaces of the two sides of the support frame 1 are fixedly sleeved with a plurality of bearing springs 43, the top ends of the bearing springs 43 are fixedly connected to the lower surface of the stirring barrel 11, and the bearing springs 43 are used to buffer the stirring barrel 11.

[0050] When the stirring blade 15 stirs the material, the stirring blade 15 drives the rotating disc 12 to rotate through the stirring rod 2, and then drives the gear ring 4 to rotate synchronously, the gear ring 4 meshes with the gear 41 when rotating, and drives the gear 41 and the eccentric block 42 connected therewith to rotate synchronously. The eccentric block 42 generates periodic centrifugal force in the rotating process due to the eccentric characteristics of its mass distribution, thereby forming a vibration effect.

[0051] The vibration is transmitted to the stirring barrel 11 through the eccentric block 42, so that the stirring barrel 11 generates a micro-vibration, which can effectively destroy the adhesion between the material and the barrel wall, prevent the occurrence of the slurry sticking phenomenon, and at the same time, enhance the flowability of the material, accelerate the speed of the material entering the main stirring area, improve the mixing efficiency, shorten the mixing time, further improve the mixing uniformity, and enhance the consistency of product quality.

[0052] In addition, in the process of generating vibration in the stirring barrel 11, the bearing spring 43 can absorb excessive vibration impact, achieve good buffering effect, and protect the overall structure of the stirring barrel 11 from being damaged.

[0053] Before the operator puts the material into the inside of the stirring barrel 11, the material needs to be weighed and added gradually, which causes the material to be moved multiple times and the operation to be complicated.

[0054] Reference is made to the accompanying drawings Figure 6 To solve the problem of multiple times of moving the material during feeding, the embodiment adopts the following technical scheme: the left side of the outer surface of the stirring barrel 11 is fixedly connected with a stabilizing frame 5, the inner side of the stabilizing frame 5 is rotatably connected with a turnover box 51, the turnover box 51 is used for feeding the material, the right side of the turnover box 51 is rotatably connected with a turnover plate 55, the left side of the turnover box 51 is fixedly connected with a plurality of observation pieces 541, the left ends of the observation pieces 541 are fixedly connected with a second fixing frame 511, the left ends of the second fixing frame 511 are fixedly connected with a plurality of counterweights 52, the counterweights 52 are used for counterbalancing the turnover box 51, the left end of the turnover box 51 is rotatably connected with a second screw rod 53, the outer surface of the second screw rod 53 is threadedly connected with a counterweight block 54, the second screw rod 53 is used for driving the counterweight block 54 to move left and right, and the upper surfaces of the observation pieces 541 are provided with scale lines, the counterweight block 54 can not only counterbalance the turnover box 51 but also point to the scale lines on the upper surfaces of the observation pieces 541.

[0055] When it is necessary to put the material into the stirring barrel 11, the operator first rotates the second screw 53 to move the counterweight 54 to the left, and the movement of the counterweight 54 not only increases the initial counterweight of the turnover box 51, but also indicates the current counterweight state of the system through the scale on the observation piece 541, so as to realize the pre-judgment and control of the weight of the material. After the counterweight adjustment is completed, the operator puts the material into the turnover box 51, at this time, the turnover plate 55 forms a block on the right side of the turnover box 51 to prevent the material from sliding down before reaching the set weight.

[0056] When the weight of the material exceeds the critical value of the current counterweight system of the turnover box 51, the turnover box 51 will turn clockwise with the material, in this process, the operator can assist the material to pour by lifting the turnover box 51, at the same time, the turnover plate 55 rotates synchronously with the turnover box 51, so that the outlet on the right side of the turnover box 51 is gradually opened, and the material can fall into the stirring barrel 11 from the right side outlet, which not only eliminates the need for multiple handling of the material, but also can set the weight of the material in advance, significantly improving the accuracy of the material. The structure not only can effectively prevent the material from being overfed, avoid waste of raw materials and risk of reaction out of control, but also can reduce the production loss caused by feeding error.

Therefore, the scope of the present disclosure should not be limited to the above-described embodiments, but should be determined by the appended claims alone, and should be limited by the equivalents of the appended claims.
