Description

Technical Field

[0001] The present invention relates to a foamed concrete production device and a preparation method, belonging to the technical field of concrete preparation. Background Art

[0002] Foamed concrete or micro-porous heat-insulating concrete is a lightweight and porous material. It is known as one of the four major inorganic foamed materials together with foamed glass, foamed ceramics, and foamed aluminum, and is the variety with the largest production and sales volume and the most promising development among the four major inorganic foamed materials. Foamed concrete has properties such as light weight, heat insulation, sound absorption, and floating.

[0003] Foamed concrete is made by continuously and gently stirring foaming agents, foam stabilizers, cement, reinforcing agents, water, gas, etc. in a mixing barrel.

[0004] Traditional foamed concrete production equipment needs to continuously introduce gas into the mixing barrel after putting various materials into the mixing barrel. The traditional way of introducing gas needs to insert an external pipeline into the mixed materials, making it impossible for the gas to quickly enter the lower layer of the mixed materials, resulting in a low degree of mixing between the gas and the mixed materials. At the same time, the operation of the entire gas injection process is relatively cumbersome. Summary of the Invention

[0005] The technical problem to be solved by the present invention is as follows: to provide a foamed concrete production device and a preparation method, which solve the problems in the prior art that the traditional way of introducing gas needs to insert an external pipeline into the mixed materials, making it impossible for the gas to quickly enter the lower layer of the mixed materials, resulting in a low degree of mixing between the gas and the mixed materials, and the operation of the entire gas injection process is relatively cumbersome.

[0006] The technical problem to be solved by the present invention is achieved by the following technical solutions: A foamed concrete production device includes

[0007] A mixing barrel, which is vertically arranged and cylindrical in shape. A mixing chamber is arranged inside the mixing barrel, and a discharging barrel is arranged at the vertical end of the mixing barrel.

[0008] A stirring rod, which is vertically inserted into the mixing chamber. The mixing barrel and the stirring rod are coaxially arranged, and the other end of the stirring rod is connected to an external driving device.

[0009] A support platform, which is horizontally arranged and remains relatively stationary with respect to the installation surface of the production device.

[0010] An installation passage, which is arranged on the support platform and vertically penetrates the support platform. The mixing barrel vertically passes through the installation passage.

[0011] A connecting support frame, which is fixed on the outside of the mixing barrel and is connected to the support platform.

[0012] An energy-absorbing component is arranged inside the support platform. Part of the energy-absorbing component extends into the installation channel and is connected to the mixing barrel.

[0013] An air guiding component is arranged on the side of the support platform away from the connecting support frame. Part of the air guiding component extends into the interior of the mixing barrel. The air guiding component is power-connected to the energy-absorbing component.

[0014] Among them, the vibration generated by the rotation of the stirring rod inside the mixing chamber is transmitted to the air guiding component through the energy-absorbing component, and the air guiding component intermittently introduces gas into the mixing chamber.

[0015] By adopting the above technical solution, the solid and liquid materials required for preparing foamed concrete are poured into the mixing chamber through the opening on the side of the mixing chamber away from the discharging barrel. The stirring rod is driven to rotate by an external driving device, so that the materials inside the mixing chamber undergo a mixing reaction. At the same time, the energy-absorbing component can absorb part of the vibration transmitted from the rotation of the stirring rod to the mixing barrel, and use the vibration energy to drive the operation of the air guiding component. The air guiding component can intermittently introduce gas into the mixing chamber during operation, so there is no need to use a pipeline to insert into the mixing material through the opening of the mixing chamber for ventilation, which improves the convenience of ventilation during the preparation of foamed concrete. And the air guiding component can promote the further mixing of the mixing materials inside the mixing chamber during operation, thereby indirectly improving the quality of foamed concrete.

[0016] The present invention is further configured as: The energy-absorbing component includes

[0017] A sliding cavity is arranged inside the support platform. The sliding cavity is distributed on the side of the installation channel away from the mixing barrel.

[0018] A sliding block is slidably arranged inside the sliding cavity. One end of the sliding block facing the mixing barrel extends into the installation channel.

[0019] An abutting block is arranged at one end of the sliding block facing the mixing barrel. The abutting block is horizontally slidably connected to the sliding block, and the abutting block abuts against the outer wall of the mixing barrel.

[0020] An energy-absorbing spring is arranged inside the sliding cavity. One end of the energy-absorbing spring abuts against the sliding block, and the other end of the energy-absorbing spring abuts against the end wall of the sliding cavity far from the opening.

[0021] By adopting the above technical solution, the abutting block directly abuts against the mixing barrel. When the mixing barrel moves towards the direction close to the sliding block due to vibration, the sliding block is pressed to move through the abutting block. At this time, the sliding block compresses the energy-absorbing spring, and the impact force of the mixing barrel is relieved under the elastic action of the energy-absorbing spring, thereby slowing down the vibration amplitude of the mixing barrel, and thus improving the overall stability of the production equipment during operation.

[0022] The present invention is further configured as: The air guiding component includes

[0023] The driving cavity is arranged laterally to the sliding cavity, and the driving cavity is communicated with the sliding cavity.

[0024] The meshing gear is rotatably arranged in the sliding cavity.

[0025] The meshing rack is fixed on the sliding block. The meshing rack is slidably arranged in the driving cavity, and the meshing rack is intermittently meshed with the meshing gear.

[0026] The transmission gear is arranged on the side of the support platform away from the connecting support frame. The transmission gear is coaxially and fixedly connected with the meshing gear.

[0027] The execution component is arranged on the side of the support platform away from the connecting support frame. The execution component is power-connected to the transmission gear, and the execution component extends into the mixing cavity.

[0028] By adopting the above technical solution, when the sliding block presses the energy-absorbing spring, it drives the meshing rack to move. The meshing rack meshes with the meshing gear to drive the meshing gear to rotate, so that the transmission gear coaxially fixed with the meshing gear rotates. After the transmission gear rotates, it can drive the execution component to operate, thus achieving the purpose of converting the vibration of the mixing barrel into the rotation of the transmission gear, and achieving the effect of power transmission and transfer on the basis of damping the mixing barrel.

[0029] The present invention is further configured as: The execution component includes

[0030] The fixed sleeve is horizontally arranged, and the fixed sleeve is fixedly connected with the support platform.

[0031] The movable rod is coaxially arranged with the fixed sleeve. The movable rod is slidably inserted into the fixed sleeve, and the end of the movable rod away from the fixed sleeve extends into the mixing cavity and is axially slidably connected with the mixing cavity.

[0032] The exhaust channel is arranged in the movable rod. The exhaust channel is provided with an opening facing the mixing cavity along the axial direction of the movable rod.

[0033] The communication component is arranged at the connection between the movable rod and the fixed sleeve. Part of the communication component is communicated with the exhaust channel.

[0034] The air inlet pipe is connected with the communication component. The air inlet pipe extends to the outside of the fixed sleeve, and the other end of the air inlet pipe is communicated with an external air supply device.

[0035] The linkage rack is fixedly connected to the outside of the movable rod. The linkage rack is horizontally aligned with the transmission gear, and the linkage rack is meshed with the outside of the transmission gear.

[0036] Wherein, the air inlet pipe transmits the gas to the exhaust channel through the communication component, and the gas in the exhaust channel enters the mixing cavity through the opening of the exhaust channel. The rotation of the transmission gear drives the linear movement of the linkage rack.

[0037] By adopting the above technical solution, the transmission gear drives the linkage rack to perform a linear reciprocating motion, so that the linkage rack drives the movable rod to perform a reciprocating linear motion. At this time, the movable rod reciprocates to insert into and pull out of the mixing cavity. During this process, the external gas supply device transmits the gas to the mixed material inside the mixing cavity through the air inlet pipe, the connecting component and the exhaust passage in sequence. During the linear motion of the movable rod, the gas can enter the mixed materials at different positions respectively, thereby improving the uniformity of the gas entering the mixed materials and being beneficial to improving the preparation quality of the foamed concrete.

[0038] The present invention is further configured as: the connecting component includes

[0039] The movable connection channel is arranged on the outer side of the movable rod inserted into the fixed sleeve.

[0040] The fixed connection channel is arranged on the inner side of the fixed sleeve facing the movable rod. The fixed connection channel can be intermittently aligned with the movable connection channel.

[0041] The air guiding channel is arranged in the movable rod. The air guiding channel connects the exhaust passage and the movable connection channel.

[0042] The pressure valve is arranged on one side of the air guiding channel. One end of the pressure valve is communicated with the air guiding channel, and the other end of the pressure valve is communicated with the air inlet pipe.

[0043] By adopting the above technical solution, during the reciprocating linear motion of the movable rod, the movable connection channel and the fixed connection channel are intermittently communicated and disconnected. When the movable rod moves away from the fixed sleeve, the movable connection channel and the fixed connection channel are communicated, and vice versa, so as to prevent the mixed material from entering the exhaust passage during the process of the movable rod inserting into the mixed material, thereby reducing the probability of complete blockage of the exhaust passage. And when the gas pressure in the air inlet pipe reaches the critical value for opening the pressure valve, after the pressure valve is opened, the air inlet pipe and the air guiding channel can be communicated without the need for the movable connection channel and the fixed connection channel to be aligned, so that the gas can be directly introduced into the exhaust passage, avoiding the problem that the communication between the movable connection channel and the fixed connection channel cannot be achieved due to too small vibration amplitude of the mixing barrel, which affects the gas supply of the mixed material.

[0044] The present invention is further configured as: a sealing component is arranged in the mixing cavity. The sealing component includes

[0045] The fixing plate is fixed on one side of the inner wall of the mixing barrel close to the discharging barrel. The fixing plates are arranged in groups of two, and a total of four groups are provided. The adjacent different groups of fixing plates are circumferentially arranged at equal angles with the stirring rod as the axis.

[0046] The flipping baffle is hinged between the two fixing plates in the same group at one end, and the other end of the flipping baffle points to the axis of the mixing barrel.

[0047] An elastic filling layer is filled and arranged at one end of the flipping baffle facing the inner wall of the mixing barrel, and the elastic filling layer is fixedly connected to the inner wall of the mixing barrel.

[0048] A driving element is built inside the fixing plate, and the driving element is power-connected to the hinge shaft of the flipping baffle.

[0049] By adopting the above technical solution, the flipping baffle is driven by the driving element to flip along the hinge. When the flipping baffle is in a non-horizontal state, the mixing cavity is connected to the discharging barrel at this time. At this time, the mixed material in the mixing cavity moves towards the discharging barrel under the action of gravity, thus achieving the purpose of discharging. On the contrary, when the flipping baffle is in a horizontal state, the mixed material in the mixing cavity cannot be discharged. By controlling the operation of the driving element, the discharging rate of the mixed material from the mixing cavity can be controlled, improving the control degree during the discharging of the material.

[0050] The present invention is further configured such that there is provided between adjacent different groups of fixing plates

[0051] An elastic filling frame, which is fixedly connected to the inner wall of the mixing barrel. The elastic filling frame is hollow-shaped and is made of an elastic material.

[0052] An elastic baffle is arranged inside the hollow position of the elastic filling frame, and the elastic baffle is fixedly connected to the elastic filling frame.

[0053] Among them, the fixing plate, the elastic filling frame and the elastic baffle are all arranged in a horizontal state, and the flipping baffle, the fixing plate, the elastic filling frame and the elastic baffle are combined to form a complete ring.

[0054] By adopting the above technical solution, when the flipping baffle is in a horizontal state, since the area where the elastic filling frame is located is small, the force-bearing area of the elastic filling frame is small. At this time, the force on the elastic filling frame is less than the force that causes the elastic filling frame to deform, and the elastic filling frame does not deform. Thus, the elastic filling frame and the flipping baffle as a whole separate the connection between the mixing cavity and the discharging barrel, further ensuring that the mixed material can be mixed in the mixing cavity for a long time. When the flipping baffle flips, at this time, due to the certain viscosity between the mixed materials and the supporting force of the flipping baffle on the mixed materials decreases, the force exerted by the mixed materials on the elastic filling frame is greater than the deformation force of the elastic filling frame. At this time, the elastic filling frame deforms, increasing the opening at the connection between the mixing cavity and the discharging barrel, and further ensuring that the mixed material in the mixing cavity can enter the discharging barrel more completely, avoiding the residue of the material in the mixing cavity.

[0055] The present invention is further configured such that at the end of the flipping baffle facing the axis of the mixing barrel, there is provided

[0056] An abutting block, which is fixedly connected to the flipping baffle. The abutting block is located on the side of the flipping baffle in the horizontal direction and is located in the vertical direction of the elastic filling frame. The abutting block can abut against the elastic filling frame.

[0057] By adopting the above technical solution, the abutment block abuts against the bottom of the elastic filling frame, so that the flip baffle can play an auxiliary supporting role for the elastic filling frame in a horizontal state, thereby avoiding the situation where the elastic filling frame is deformed prematurely due to excessive weight of the material in the mixing chamber.

[0058] The present invention is further configured as follows: the opening of the installation channel is rectangular, four groups of energy absorbing components are provided and are respectively arranged on four sides of the installation channel, and the number of the air guide components is consistent with that of the energy absorbing components.

[0059] By adopting the above technical solution and setting up multiple groups of energy absorbing components, it is possible to ensure that the vibrations in all directions of the mixing barrel are absorbed and converted to the greatest extent, thereby reducing energy loss and waste.

[0060] A method for preparing a foamed concrete production device, the method comprising:

[0061] In the first step, solid and liquid materials required for preparing foamed concrete are poured into the mixing chamber through an opening on one side of the mixing chamber away from the discharge barrel;

[0062] The second step is to start the stirring rod so that the stirring rod drives the materials in the mixing chamber to rotate and mix them fully;

[0063] The third step is to continuously introduce gas materials required for preparing foamed concrete into the mixing chamber through the gas guide component;

[0064] The fourth step is to fully stir the solid, liquid and gas materials required for preparing the foamed concrete by continuous rotation of the stirring rod to form the foamed concrete;

[0065] The fifth step is to discharge the foamed concrete from the discharge barrel to the outside of the mixing chamber.

[0066] By adopting the above technical solution and the above process, it is possible to ensure that various materials are fully mixed and that the gas is evenly distributed in the mixed material, which is beneficial to improving the quality of the foamed concrete.

[0067] The beneficial effects of the present invention are:

[0068] 1. An energy-absorbing component is provided to absorb the shaking part of the mixing barrel, and the vibration energy is used to drive the operation of the gas guide component. The gas guide component can intermittently introduce gas into the mixing chamber during operation, so there is no need to use a hose to insert the mixed material from the opening of the mixing chamber for ventilation, which improves the convenience of ventilation during the preparation of foamed concrete. In addition, the gas guide component can promote further mixing of the mixed materials in the mixing chamber during operation, thereby indirectly improving the quality of the foamed concrete.

[0069] 2. The flipping baffle is driven to flip along the hinge by the driving element. When the flipping baffle is in a non-horizontal state, the mixing chamber is connected to the discharge barrel at this time. At this time, the mixed material in the mixing chamber moves towards the discharge barrel under the action of gravity, thus achieving the purpose of discharging materials. On the contrary, when the flipping baffle is in a horizontal state, the mixed material in the mixing chamber cannot be discharged. By controlling the operation of the driving element, the discharge rate of the mixed material from the mixing chamber can be controlled, improving the control degree during material discharge.

[0070] 3. The transmission gear drives the linkage rack to perform a linear reciprocating motion, so that the linkage rack drives the movable rod to perform a reciprocating linear motion. At this time, the movable rod reciprocates to insert into and pull out of the mixing chamber. During this process, the external air supply device transmits gas to the mixed material inside the mixing chamber through the air inlet pipe, the connecting component and the exhaust channel in sequence. During the linear motion of the movable rod, the gas can enter the mixed material at different positions respectively, thereby improving the uniformity of the gas entering the mixed material and being beneficial to improving the preparation quality of foamed concrete.

The airbag 52 is made of elastic material, and an air pump directly connected to the connecting pipe 50 can be installed on the fixing ring 51. The air outside the production equipment is pressed into the inflation interval of the expansion layer 53 through the operation of the air pump. The expansion layer 53 is located below the elastic filling frame 44. When the elastic filling frame 44 is turned down, the elastic baffle 45 just abuts against the outer side of the expansion layer 53. The elastic baffle 45 and the expansion layer 53 are both made of elastic wear-resistant material.

[0087] When the mixing barrel 10 shakes due to the rotation of the stirring rod 12, the mixing barrel 10 squeezes the airbag 52, so that the gas in the airbag 52 is pressed into the inflation interval of the expansion layer 53 through the connecting pipe 50, so that the expansion layer 53 expands. In the process of squeezing and deforming the airbag 52, the shaking degree of the mixing barrel 10 can be slowed down, thereby improving the stability of the mixing barrel 10. At the same time, after the expansion layer 53 expands, the space in the discharge barrel 15 is reduced. When the mixing barrel 10 moves to the starting position, due to the reduction of squeezing of the airbag 52, the gas in the inflation interval of the expansion layer 53 returns to the airbag 52 through the connecting pipe 50. At this time, the expansion degree of the expansion layer 53 is reduced, and the space in the discharge barrel 15 becomes larger. When the driving element drives the flip baffle 42 to flip downward, the mixing chamber 11 and the discharge barrel 15 are connected. At this time, the concrete in the mixing chamber 11 enters the discharge barrel 15, and passes through the above-mentioned expansion layer 53, so that the concrete in the discharge barrel 15 is intermittently squeezed, so that the concrete is promoted to be discharged from the opening of the discharge barrel 15 when being squeezed. If the stirring rod 12 does not move when the concrete is discharged from the discharge barrel 15, the mixing barrel 10 does not shake at this time, and the gas can be pressed into the inflation interval in the expansion layer 53 through the connecting pipe 50 by starting the air pump, or the gas can be extracted from the inflation interval in the expansion layer 53, thereby completing the above process. When the expansion layer 53 abuts against the elastic baffle 45, it expands. At this time, the elastic baffle 45 expands with the expansion layer 53, thereby achieving the purpose of squeezing the concrete in the discharge barrel 15.

[0088] A preparation method of a foamed concrete production device, the method comprising

[0089] First step, pour the solid and liquid materials required for preparing foamed concrete into the inside of the mixing chamber 11 through the opening on the side of the mixing chamber 11 away from the discharge barrel 15;

[0090] Second step, start the stirring rod 12 to drive the materials in the mixing chamber 11 to rotate and mix fully, and at the same time, the materials in the mixing chamber 11 impact the mixing barrel 10 to make the mixing barrel 10 shake;

[0091] Third step, during the continuous shaking of the mixing barrel 10, the shaking process of the mixing barrel 10 is converted into a linear motion process of the movable rod 34 through the action of the energy absorption component 20 and the air guiding component 30. The gas materials are intermittently and continuously introduced into the inside of the mixing chamber 11 through the intermittent communication of the fixed connection channel 38 and the movable connection channel 37 in the air guiding component 30. At the same time, the air supply amount can also be increased to increase the pressure value in the air inlet pipe 36. After the pressure valve 31 is opened, the gas is introduced into the air guiding channel 39 through the pressure valve 31;

[0092] Fourth step, the solid, liquid, and gas materials required for preparing foamed concrete are fully stirred by the continuous rotation of the stirring rod 12. During this process, the linear motion of the movable rod 34 can play an auxiliary mixing role for the mixed materials in the mixing chamber 11, and finally form foamed concrete;

[0093] Fifth step, the driving element in the closing component 40 operates to turn the turning baffle 42 downward. At this time, the foamed concrete presses down and deforms the elastic filling frame 44 and the elastic baffle 45. At the same time, the foamed concrete enters the discharge barrel 15 from the mixing chamber 11, and then the foamed concrete is discharged from below the discharge barrel 15 to the outside of the mixing barrel 10.

[0094] Through the above process, it can ensure the full mixing of various materials and ensure the uniform distribution of gas in the mixed materials, which is beneficial to improving the quality of foamed concrete.

[0095] By pouring the solid and liquid materials required for preparing foamed concrete into the mixing chamber 11 through the opening on the side of the mixing chamber 11 far away from the discharging barrel 15, and driving the stirring rod 12 to rotate through an external driving device, the materials inside the mixing chamber 11 can undergo a mixing reaction. At the same time, the energy absorption component 20 can absorb part of the vibration transmitted by the rotation of the stirring rod 12 to the mixing barrel 10, and use the vibration energy to drive the air guiding component 30 to operate. During the operation process, the air guiding component 30 can intermittently introduce gas into the mixing chamber 11, so that there is no need to use a hose to insert into the mixed materials from the opening of the mixing chamber 11 for ventilation, improving the convenience of ventilation during the preparation of foamed concrete. And during the operation process, the air guiding component 30 can promote the further mixing of the mixed materials inside the mixing chamber 11, thus indirectly improving the quality of foamed concrete.

[0096] The abutting block 21 is in direct contact with the mixing barrel 10. When the mixing barrel 10 moves towards the direction close to the sliding block 22 due to vibration, the sliding block 22 is pressed to move by the abutting block 21. At this time, the sliding block 22 compresses the energy absorption spring 24, and under the elastic action of the energy absorption spring 24, the impact force of the mixing barrel 10 is relieved, thereby reducing the vibration amplitude of the mixing barrel 10, and thus improving the overall stability of the production equipment during operation.

[0097] During the process of the sliding block 22 pressing the energy absorption spring 24, the meshing rack 25 is driven to move. The meshing rack 25 meshes with the meshing gear 27 to drive the meshing gear 27 to rotate, so that the transmission gear 29 fixed coaxially with the meshing gear 27 rotates. After the transmission gear 29 rotates, it can drive the execution component to operate, thus achieving the purpose of converting the vibration of the mixing barrel 10 into the rotation of the transmission gear 29, and achieving the effect of power transmission transfer on the basis of damping the mixing barrel 10.

[0098] The transmission gear 29 drives the linkage rack 32 to perform a linear reciprocating motion, so that the linkage rack 32 drives the movable rod 34 to perform a reciprocating linear motion. At this time, the movable rod 34 reciprocally inserts into and withdraws from the mixing chamber 11. During this process, an external gas supply device transmits gas to the mixed materials inside the mixing chamber 11 through the air inlet pipe 36, the connection component and the exhaust channel 35 in sequence. During the linear motion of the movable rod 34, the gas can enter the mixed materials at different positions respectively, thus improving the uniformity of the gas entering the mixed materials, which is beneficial to improving the preparation quality of foamed concrete.

[0099] During the reciprocating linear motion of the movable rod 34, the movable connection channel 37 and the fixed connection channel 38 are intermittently connected and disconnected. When the movable rod 34 moves away from the fixed sleeve 33, the movable connection channel 37 and the fixed connection channel 38 are connected, and vice versa, so as to prevent the mixing material from entering the exhaust channel 35 during the insertion of the movable rod 34 into the mixing material, thereby reducing the probability of complete blockage of the exhaust channel 35. And when the gas pressure in the intake pipe 36 reaches the critical value for opening the pressure valve 31, after the pressure valve 31 is opened, the intake pipe 36 and the air guide channel 39 can be connected without the need for the alignment of the movable connection channel 37 and the fixed connection channel 38, so that the gas can directly enter the exhaust channel 35, avoiding the problem that the connection between the movable connection channel 37 and the fixed connection channel 38 cannot be connected due to too small vibration amplitude of the mixing barrel 10, which affects the supply of the mixing material.

[0100] The flipping baffle 42 is driven by a driving element to flip along the hinge. When the flipping baffle 42 is in a non-horizontal state, the mixing chamber 11 is connected to the discharging barrel 15 at this time. At this time, the mixing material in the mixing chamber 11 moves towards the discharging barrel 15 under the action of gravity, thus achieving the purpose of discharging. On the contrary, when the flipping baffle 42 is in a horizontal state, the mixing material in the mixing chamber 11 cannot be discharged. By controlling the operation of the driving element, the discharging rate of the mixing material from the mixing chamber 11 can be controlled, improving the control degree during the discharging of the material.

[0101] When the flipping baffle 42 is in a horizontal state, since the area occupied by the elastic filling frame 44 is small, the force-bearing area of the elastic filling frame 44 is small. At this time, the force on the elastic filling frame 44 is less than the force that causes the elastic filling frame 44 to deform, and the elastic filling frame 44 does not deform. Thus, the elastic filling frame 44 and the flipping baffle 42 as a whole separate the connection between the mixing chamber 11 and the discharging barrel 15, further ensuring that the mixing material can be mixed in the mixing chamber 11 for a long time. When the flipping baffle 42 flips, at this time, due to the certain viscosity between the mixing materials and the supporting force of the flipping baffle 42 on the mixing material decreasing, the force exerted by the mixing material on the elastic filling frame 44 is greater than the deformation force of the elastic filling frame 44. At this time, the elastic filling frame 44 deforms, increasing the opening at the connection between the mixing chamber 11 and the discharging barrel 15, which can further ensure that the mixing material in the mixing chamber 11 enters the discharging barrel 15 more completely, avoiding the residue of the material in the mixing chamber 11.

[0102] By the abutting block 46 abutting against the bottom of the elastic filling frame 44, the flipping baffle 42 can play an auxiliary supporting role for the elastic filling frame 44 in the horizontal state, avoiding the situation that the elastic filling frame 44 deforms in advance due to the excessive weight of the material in the mixing chamber 11.

[0103] By setting multiple sets of energy-absorbing components 20, it is possible to ensure to the greatest extent the absorption and conversion of vibrations in all directions of the mixing barrel 10, reducing energy loss and waste.

[0104] During operation, the materials for preparing concrete are poured into the mixing chamber 11 through the upper opening of the mixing chamber 11. At this time, the sealing component 40 separates the mixing chamber 11 and the discharge barrel 15, and the stirring rod 12 rotates to fully mix and stir the materials in the mixing chamber 11. During the stirring process of the stirring rod 12, the mixing barrel 10 shakes due to the impact of the materials in the mixing chamber 11, thereby squeezing the sliding blocks 22 in different directions. After being subjected to pressure, the sliding blocks 22 move away from the mixing barrel 10, causing the energy-absorbing springs 24 to be compressed. The energy-absorbing springs 24 can absorb part of the energy of the shaking of the mixing barrel 10, achieving the purpose of shock absorption. At the same time, the sliding blocks 22 drive the meshing rack 25 to move. The meshing rack 25 meshes with the meshing gear 27. As the meshing rack 25 continues to move, the meshing gear 27 rotates. Since the meshing gear 27 and the transmission gear 29 are coaxially arranged, the transmission gear 29 rotates. At this time, the transmission gear 29 drives the linkage rack 32 to move linearly towards the mixing barrel 10, causing the movable rod 34 to insert into the mixing chamber 11. At this time, the fixed connection channel 38 and the movable connection channel 37 change from a disconnected state to a connected state. The gas required for preparing foamed concrete is input into the fixed connection channel 38 through the air inlet pipe 36, and is transmitted to the air guide channel 39 through the movable connection channel 37, and finally transmitted to the exhaust channel 35 through the air guide channel 39. The gas in the exhaust channel 35 is directly introduced into the concrete mixture in the mixing chamber 11, thereby achieving the purpose of ventilating the concrete. At the same time, the sealing component 40 plays the role in the above process during the entire working state, and plays the role of assisting in stirring the concrete in the mixing chamber 11 during the axial movement of the movable rod 34. That is, when the movable rod 34 inserts into the concrete, it squeezes and separates the concrete, and the voids generated when the movable rod 34 is pulled out of the concrete are filled with the concrete, thereby achieving the purpose of assisting in stirring. During the process of the concrete being discharged from the discharge barrel 15, through the above process, the expansion layer 53 abuts against the elastic baffle 45 to assist in squeezing the concrete. During the process of the concrete being stirred by the stirring rod 12 in the mixing chamber 11, if the shaking amplitude of the mixing barrel 10 is too small, resulting in the inability to connect the fixed connection channel 38 and the movable connection channel 37, at this time, the air pressure in the air inlet pipe 36 gradually increases. When the air pressure in the air inlet pipe 36 is greater than the opening pressure of the pressure valve 31, the gas in the air inlet pipe 36 directly enters the air guide channel 39 through the pressure valve 31, and the gas is discharged into the mixing chamber 11 through the above process. The concrete discharged from the discharge barrel 15 directly enters the transferred concrete mixer truck or other storage equipment.
