As shown in fig. 1 to 2, in a first embodiment of the present invention, an automatic production device for self-insulation building blocks is provided, which includes a foaming tank and an output pipe for outputting foam (the foaming tank and the output pipe are both in the prior art and are not shown in the specification and the drawing), a filter plate 30 is disposed at the connection position of the foaming tank and the output pipe, and a transition cavity 1 is further included, wherein the transition cavity 1 is communicated with the foaming tank and the output pipe, that is, one end of the transition cavity 1 is communicated with the foaming tank, the other end of the transition cavity is communicated with the output pipe, the transition cavity 1 is a cavity formed in a housing and capable of bearing foam, the filter plate 30 is disposed at the connection position of the transition cavity 1 and the output pipe, a foam breaking mechanism is disposed in the transition cavity 1, and a flow detector mechanism is disposed in the output pipe, and the foam breaking mechanism moves to the filter plate 30 to break the foam based on a detection signal of the flow detector.

Specifically, the transition cavity 1 is in a circular tube structure, the transition cavity 1 is connected with the foaming tank through a flange, the transition cavity 1 is connected with the output pipe through the flange, foam firstly enters the transition cavity 1 from the foaming tank, sequentially passes through the foam breaking mechanism and the filter plate 30 in the transition cavity 1, and then enters the output pipe, the initial position of the foam breaking mechanism is positioned at the joint of the foaming tank and the transition cavity 1, at the moment, the distance between the foam breaking mechanism and the filter plate 30 is furthest, the foam cannot be broken when passing through the foam breaking assembly, after the foam with the mixed size passes through the filter plate 30, the small-size foam smoothly enters the output pipe through the filter holes on the filter plate 30, and the large-size foam which cannot pass through the filter holes on the filter plate 30 is left in the transition cavity 1 between the foam breaking mechanism and the filter plate 30 along with the increase of the large-size foam, the filter holes on the filter plate 30 are necessarily blocked, so that small-size foam is difficult to pass through, the small-size foam entering the output pipe is reduced, a foam flow detection mechanism (namely a flow detector, which is not described in detail in the prior art) detects the reduction of the foam flow in the output pipe and converts the foam flow into an electric signal to be transmitted to a foam breaking mechanism, the foam breaking mechanism moves towards the direction close to the filter plate 30 under the action of a driving source of the foam breaking mechanism based on the signal, after contacting large-size foam, the foam breaking mechanism breaks the foams to break the foams into small-size foam so as to smoothly enter the output pipe through the filter holes on the filter plate 30, after the foam flow detection mechanism detects that the foam flow in the output pipe is recovered to be normal, the electric signal is converted again and transmitted to the foam breaking mechanism, the foam breaking mechanism then returns to the original position under the action of its own drive source based on the signal.

The invention has the beneficial effects that: the gradual accumulation of the large-size foam causes the filter plate 30 to generate gradually increasing resistance to the foam passing through the transition cavity 1 to enter the output pipe, the amount of the foam entering the output pipe is reduced, the flow detection mechanism detects the reduction of the foam flow and turns into an electric signal, the electric signal is transmitted to the foam breaking mechanism, then the foam breaking mechanism moves towards the filter plate 30 based on the signal, and the large-size foam accumulated at the filter plate 30 is broken, so that the large-size foam is broken into small-size foam to smoothly enter the output pipe through the filter plate 30.

Preferably, the foam breaking assembly comprises a breaking filter plate 10 and a driving mechanism for driving the breaking filter plate 10 to move in the transition cavity 1, wherein the size of the filter holes on the breaking filter plate 10 is larger than that of the filter holes on the filter plate 30, and the positions of the filter holes on the breaking filter plate 10 are staggered with those of the filter holes on the filter plate 30.

Specifically, the driving mechanism receives the signal about the decrease of the foam quantity in the output pipe from the foam flow detecting mechanism, and then drives the rupture filter plate 10 to move towards the filter plate 30, because the positions of the filter holes on the rupture filter plate 10 are staggered with those on the filter plate 30, large-size foam at the staggered positions of the filter holes on the rupture filter plate 10 and the filter plate can be extruded and ruptured, after the foam flow detecting mechanism detects that the foam flow in the output pipe is normal, the driving mechanism drives the rupture filter plate 10 to return to the initial position, wherein the driving mechanism can be a mechanism for driving the rupture filter plate 10 to reciprocate in the transition cavity 1, such as a belt transmission assembly, a screw transmission assembly and the like, which are all the prior art, and are not repeated herein.

Further, the rupture filter plate 10 is slidably connected with the inner wall of the transition chamber 1 through an auxiliary frame 12, and the rupture filter plate 10 is vertically slidably arranged on the auxiliary frame 12, and the sliding direction of the rupture filter plate is the same as the magnetic attraction direction of the main electromagnet to the auxiliary electromagnet.

Specifically, when the magnetic force of the main electromagnet is increased and the magnetic force of the auxiliary electromagnet is unchanged, the magnetic attraction of the main electromagnet to the auxiliary electromagnet is increased, when the magnetic attraction between the main electromagnet and the auxiliary electromagnet reaches a certain value, the auxiliary electromagnet can drive the rupture filter plate 10 to vertically move upwards on the auxiliary frame 12, the gravity of the rupture filter plate 10 is overcome, the magnetic attraction is different, the upward movement distance of the rupture filter plate 10 is different, the magnetic force of the main electromagnet is alternately changed or irregularly changed in size in the process that the rupture filter plate 10 is close to the filter plate 30, the rupture filter plate 10 can vertically reciprocate on the auxiliary frame 12, so that the rupture filter plate 10 can form extrusion rupture effect on large-size foam with the filter plate 30 in the axial direction, and can also be frequently staggered in the radial direction, so as to form rubbing movement on the large-size foam, and improve the rupture efficiency of the foam.

Specifically, when the number of the first breaking needles 13 is consistent with the number of the filter holes on the filter plate 30, the filter plate 30 is completely blocked by inserting the first breaking needles 13 into the filter holes, so that small-sized foam is prevented from flowing into the output pipe, when the number of the first breaking needles 13 is smaller than the number of the filter holes on the filter plate 30, the edge of the filter plate 30 is difficult to accurately align with one filter hole each time due to the radial elastic connection between the edge of the filter plate 30 and the inner wall of the transition cavity 1, residual foam and substances which are not melted in foaming agents are adhered in the filter holes, and the simple screening is difficult to remove.

In this embodiment provided by the invention, the magnetic force change of each primary electromagnet is changed regularly, the distance that each secondary electromagnet drives the rupture filter plate 10 to move is controlled, so that a plurality of first rupture needles 13 on the rupture filter plate 10 are replaced by a plurality of second rupture needles which are arranged regularly, the filter plate 30 is fixedly connected with the inner wall of the transition cavity 1, the filter holes on the filter plate 30 are also distributed regularly, the number of the second rupture needles is smaller than that of the filter holes, the passage of small-size foam is not influenced while large-size foam is ruptured, and the distance that each second rupture needle moves is controlled, so that each row of filter holes can be accurately changed back and forth in the transition cavity 1 to allow the second rupture needles to be inserted, and the adhered substances which are not melted can be changed alternately or irregularly in size while the residual foam is clear, so that the efficiency of large-size foam rupture is improved.

The first breaking needle 13 has the same structure as the second breaking needle.

During operation, foaming agent in the foaming tank can continuously generate foams of different sizes in the foaming process, after the foam quantity reaches the conveying standard, the output pipe outputs the foam, when the foam passes through the transition cavity 1, the static filter assembly 2 is used for filtering once, the foam which cannot pass through the filter holes of the static filter assembly 2 is continuously left in the foaming tank and is stirred and destroyed to form the foam of small size, the filter holes of the static filter assembly 2 enter the transition cavity 1, the foam which enters the transition cavity 1 can enter the output pipe after passing through the dynamic filter assembly 3, the foam with the size larger than the filter hole size on the dynamic filter assembly 3 is left in the transition cavity 1, more and more foam with the larger size is accumulated in the transition cavity 1, the dynamic filter assembly 3 starts to touch from the position farthest from the static filter assembly 2, during the period, the foam with the smaller size can still pass through the filter holes on the dynamic filter assembly 3, the foam with the larger size is pushed to the static filter assembly 2, the static filter assembly 2 is pushed to move through the filter assembly 3, the foam with the larger size can enter the transition cavity 1 after the foam is closed, the foam with the larger size is gradually reduced, the foam is gradually pushed down from the filter assembly 2, the filter assembly is gradually opened, the foam is gradually reaches the filter assembly 2 after the filter hole is opened, and the filter assembly is gradually opened, and the filter assembly is gradually is opened, and the filter is gradually is opened from the filter assembly 2 after the filter assembly is opened, the filter hole is gradually is opened, and the filter is gradually is opened.

The invention has the beneficial effects that: firstly, through setting up quiet filter component 2 in transition chamber 1, can play a filter action to the foam that is carried, through setting up dynamic filter component 3 in transition chamber 1, can play the secondary filter action to the foam that passes through quiet filter component 2.

Secondly, when the movable filter assembly 3 is close to the static filter assembly 2, the filter holes on the static filter assembly 2 are closed, and the movable filter assembly 3 and the static filter assembly 2 can squeeze the foams filtered by the movable filter assembly 3, so that the foams are broken to form foams which can pass through the filter holes of the movable filter assembly 3, and the size of the foams mixed with concrete can be effectively controlled within a range.

Thirdly, open and shut of filtration pore on static filter assembly 2 at every turn for foam in the foaming tank forms action of intermittent type formula, ration material loading when exporting through the output tube, and the foam volume of entering concrete mixing tank at every turn can not be very much like this, can make the mixing efficiency and the mixing effect between foam and the concrete all improve to some extent.

Preferably, the static filter assembly 2 comprises a static frame body 20 fixedly connected to the transition cavity 1, a main filter plate 21 and an auxiliary filter plate 22 are arranged at the part of the static frame body 20 located in the transition cavity 1, the main filter plate 21 is rotatably arranged on the static frame body 20, a first elastic piece is arranged between the main filter plate 21 and the static frame body 20, the auxiliary filter plate 22 and the static frame body 20 are fixedly arranged, a pull rope 23 is connected between the main filter plate 21 and the dynamic filter assembly 3, the dynamic filter assembly 3 is driven to rotate through the pull rope 23 in the stroke far away from the static frame body 20, and the filter holes on the main filter plate 21 and the filter holes on the auxiliary filter plate 22 are gradually overlapped.

Specifically, the static frame body 20 is of a circular ring structure, one end of the transition cavity 1, which is close to the foaming tank, is separated by a part, the part is connected with the foaming tank through a flange, the static frame body 20 is fixedly connected with the transition cavity 1, the main filter plate 21 and the auxiliary filter plate 22 are of a circular cake structure, the axes of the main filter plate 21 and the auxiliary filter plate 22 coincide with the axis of the transition cavity 1, so that the first elastic piece can be arranged on the axis of the main filter plate 21 and the auxiliary filter plate 22, for example, the main filter plate 21 and the auxiliary filter plate 22 are connected on the axis through a circular shaft, the first elastic piece is a torsion spring, one end of the torsion spring is fixedly connected with the main filter plate 21, the other end of the torsion spring is fixedly connected with the auxiliary filter plate 22, and sliding fit is carried out between the opposite surfaces of the main filter plate 21 and the auxiliary filter plate 22.

When the movable filter assembly 3 is far away from the auxiliary filter plate 22 in operation, the main filter plate 21 is pulled to rotate along the axis thereof by the pull rope 23, in the process, a cavity for the main filter plate 21 to rotate is arranged on the static frame body 20, two fixed pulleys are arranged in the cavity, as shown in the figure and the drawing, one fixed pulley axially and horizontally radially parallels with the main filter plate 21, the fixed pulley converts the original horizontal direction of one end of the pull rope 23 connected with the main filter plate 21 into the vertical direction, the other fixed pulley changes the vertical direction of the end of the pull rope 23 into the horizontal direction tangential with the edge of the main filter plate 21, thus the axial pulling force of the movable filter assembly 3 to the pull rope 23 can form the pulling force on the circumference of the main filter plate 21 after passing through the two fixed pulleys, the length of the pull rope 23 needs to meet the whole distance from incomplete coincidence of the filtering holes on the main filter plate 21 and the filtering holes on the auxiliary filter plate 22 to complete coincidence, the movable filter assembly 3 can reach the position farthest from the static frame body 20 on the transition cavity 1, but when the movable filter assembly 3 is contacted with the auxiliary filter plate 22, the filter holes on the main filter plate 21 cannot be completely overlapped with the filter holes on the auxiliary filter plate 22, otherwise, in the process that the movable filter assembly 3 is close to the auxiliary filter plate 22, the foam with larger size is pushed back to the foaming tank by the movable filter assembly 3, so that when the distance of the movable filter assembly 3 away from the auxiliary filter plate 22 reaches a certain value, for example, before one third or one half of the farthest distance between the movable filter assembly 3 and the auxiliary filter plate 22, the pull rope 23 is in a soft state and cannot generate pulling force on the main filter plate 21, when the movable filter assembly 3 is away from one third or one half of the farthest distance between the movable filter assembly 3 and the auxiliary filter plate 22, the pull rope 23 starts to tighten, when the movable filter assembly 3 is away from the auxiliary filter plate 22, the pull rope 23 starts to generate pulling force on the main filter plate 21, the elastic force of the first elastic member increases until the distance between the movable filter assembly 3 and the auxiliary filter plate 22 reaches the farthest, and at this time, the filter holes on the main filter plate 21 completely coincide with the filter holes on the auxiliary filter plate 22, so that the foam can pass through the transition cavity 1 from the foaming tank at the maximum flow rate.

In the stroke of the movable filter assembly 3 near the auxiliary filter plate 22, due to the rebound force of the first elastic piece, when the movable filter assembly 3 is initially near the front two thirds or one half of the distance of the auxiliary filter plate 22, the main filter plate 21 and the auxiliary filter plate 22 rotate relatively, the filter holes on the main filter plate 21 and the auxiliary filter plate 22 are gradually staggered, but the process does not influence the passing of foam, but can influence the passing quantity of foam, the foam passing through the filter holes on the movable filter assembly 3 can be continuously introduced into the output pipe to be output, the foam which cannot pass through the filter holes on the movable filter assembly 3 is filtered in the transition cavity 1, and after the filter holes on the main filter plate 21 and the filter holes on the auxiliary filter plate 22 are completely staggered, the movable filter assembly 3 is continuously moved to be matched with the auxiliary filter plate 22 to squeeze and crack the foam with a larger size in the transition cavity 1.

Preferably, the filter holes on the main filter plate 21 are divided into a plurality of groups of filter holes which are arranged in parallel in the circumferential direction, each group of filter holes is arranged in parallel in the radial direction and the arc length is gradually prolonged, the arrangement of two adjacent groups of filter holes is also arranged alternately in the radial direction, and the arrangement of the filter holes on the auxiliary filter plate 22 is the same as that of the filter holes on the main filter plate 21.

Specifically, when the filter holes on the main filter plate 21 are completely overlapped with the filter holes on the auxiliary filter plate 22, all the positions on the main filter plate 21 are axially aligned with all the positions on the auxiliary filter plate 22, and when the filter holes on the main filter plate 21 are completely misaligned with the filter holes on the auxiliary filter plate 22, the filter holes on the same circular arc on the auxiliary filter plate 22 are blocked by the part between the radially adjacent two filter holes on the main filter plate 21, otherwise, the filter holes on the same circular arc on the main filter plate 21 are blocked by the part between the radially adjacent two filter holes on the auxiliary filter plate 22; in the prior art, the opening and closing of the holes are realized by rotating two plates, for example, a plurality of groups of circular holes are formed in parallel in the circumferential direction, and each group of circular holes are arranged in parallel in the radial direction, but the distance between two circular holes at adjacent positions in the circumferential direction is prolonged along with the increase of the radial dimension, so that the utilization rate of the plates is lower, and the problem can occur in an opening mode of the like.

Preferably, the dynamic filter assembly 3 comprises a driving part for driving the filter plate 30 to move, kinetic energy is transferred between the driving part and the filter plate 30 through magnetic force, the pull rope 23 is connected with the main filter plate 21 and the driving part, the driving part comprises a second screw rod transmission mechanism arranged outside the transition cavity 1, the second screw rod transmission mechanism comprises a second screw rod 31 and the filter plate 30, the kinetic energy is transferred between the second screw rod transmission mechanism and the filter plate 30 through magnetic force, and the pull rope 23 is connected with the main filter plate 21 and the second screw rod 31.

The driving piece drives the filter plate 30 to move in the direction of approaching or keeping away from the auxiliary filter plate 22 in the filter cavity to realize the filtration of the foam in the transition cavity 1, and the foam which cannot permeate the filter holes on the filter plate 30 is pushed to the auxiliary filter plate 22 for rupture treatment, the second wire block 31 and the filter plate 30 are provided with magnet blocks, and the two magnet blocks are mutually attracted, wherein the time interval of the driving piece driving the filter plate 30 to move towards the direction of approaching the auxiliary filter plate 22 can be adjusted according to actual requirements, namely, the time interval of the driving piece driving the filter plate 30 to move towards the direction of approaching the auxiliary filter plate 22 can be adjusted according to the fact that the foam output by the foaming tank contains the foam which cannot permeate the filter holes on the filter plate 30, if the foam quantity is more, the time of approaching the filter plate 30 to the auxiliary filter plate 22 can be shortened, otherwise, the time of approaching the filter plate 30 to the auxiliary filter plate 22 can be increased, so that the accumulated foam quantity of the filter cavity is excessive, and if the foam accumulated in the transition cavity 1 moves towards the auxiliary filter plate 22, part of the foam is pushed back into the foaming tank again, and the efficiency of the foam can be reduced for rupture treatment.

In a fifth embodiment of the present invention, the pull cord 23 has elasticity, and the stiffness coefficient of the first elastic member is greater than the stiffness coefficient of the pull cord 23.

Specifically, in the first embodiment of the present invention, it is mentioned that the length of the pulling cord 23 is required to satisfy the entire distance from the filter hole on the main filter plate 21 to the filter hole on the auxiliary filter plate 22, and the movable filter assembly 3 may reach the position farthest from the static frame 20 on the transition chamber 1, wherein the filter hole on the main filter plate 21 cannot completely coincide with the filter hole on the auxiliary filter plate 22 when the movable filter assembly 3 is in contact with the auxiliary filter plate 22, or the relatively large-sized foam is pushed back to the foaming tank by the movable filter assembly 3 during the process of the movable filter assembly 3 approaching the auxiliary filter plate 22, so that the pulling cord 23 preferably cannot generate a pulling force on the main filter plate 21 when the movable filter assembly 3 is farthest from the auxiliary filter plate 22, for example, before the farthest from the auxiliary filter plate 22 or before one-third or one-half of the distance between the two is reached, and the pulling cord 23 starts to tighten when the movable filter assembly 3 is farthest from the auxiliary filter plate 22, and the pulling cord 23 starts to generate a pulling force on the main filter plate 21 when the movable filter assembly 3 is further away from the auxiliary filter plate 22.

The pull rope 23 is not elastic, when the wire block approaches the auxiliary filter plate 22, the main filter plate 21 is rotated by the resilience force of the first elastic element to pull a part of the pull rope 23 into the static frame 20, but when the wire block approaches the auxiliary filter plate 22 after the main filter plate 21 is not rotated any more, the pull rope 23 loses the power of entering the static frame 20, so that the stacked pull rope 23 affects the shortest distance between the wire block and the static frame 20, the shortest distance between the filter plate 30 and the auxiliary filter plate 22 cannot be abutted, the extrusion effect on foam is reduced, therefore, the pull rope 23 is preferably replaced by elastic, so that the wire block contacts with the static frame 20 at the beginning in the process of keeping the wire block away from the static frame 20, the pull rope 23 is basically in the static frame 20, so that the stacking problem does not occur, because the stiffness coefficient of the first elastic member is greater than that of the pull rope 23, the pull rope 23 is stretched and the elastic force is gradually increased, when the elastic force of the pull rope 23 can overcome the elastic force of the first elastic member, the main filter plate 21 can rotate until the filter holes on the main filter plate 21 are completely overlapped with the filter holes on the auxiliary filter plate 22, when the wire block approaches the static frame 20, under the elastic force of the first elastic member, the filter holes on the main filter plate 21 can be reversely rotated and gradually staggered with the filter holes on the auxiliary filter plate 22, and before the filter holes on the two filter plates are completely staggered, the pull rope 23 is basically still in a stretched state, after the filter holes on the main filter plate 21 and the filter holes on the auxiliary filter plate 22 are completely staggered, the main filter plate 21 does not rotate any more, so that the wire block gradually contracts and retracts into the static frame 20 in the process of continuously approaching the static frame 20, and the problem of stacking of the pull rope 23 is avoided.

The limiting assembly 4 comprises two limiting gaps 40 formed in the edge of the main filter plate 21, the distance between the two limiting gaps 40 is the distance from the completely misaligned to the completely misaligned distance between the filtering holes in the main filter plate 21 and the filtering holes in the auxiliary filter plate 22, a deflector rod 41 is hinged to the static frame 20, the hinge shaft between the two is axially parallel to the horizontal radial direction of the transition cavity 1, a third elastic piece is arranged at the hinge joint between the static frame 20 and the deflector rod 41, one end of the deflector rod 41 is hinged with a limiting insert block 42, the hinge shaft between the two is axially parallel to the axial direction of the transition cavity 1, the limiting insert block 42 is inserted into the limiting gap 40, a stop block 43 is arranged on the deflector rod 41 and is close to the limiting insert block 42, the stop block 43 limits the limiting insert block 42 to swing towards the direction where the stop block 43 is located, a push rod 44 is further arranged on the static frame 20 in a sliding mode, the sliding direction of the push rod 44 is parallel to the axial direction of the transition cavity 1, the other end 44 is in sliding contact with the deflector rod 41, the sliding direction of the push rod 44 is parallel to the axial direction of the transition cavity 1, and the elastic piece 33 is connected with the triggering wire 33 along the sliding direction of the fourth elastic piece.

Specifically, in the process that the filtering holes on the main filter plate 21 and the filtering holes on the auxiliary filter plate 22 are completely misaligned to completely misaligned, the rotation of the main filter plate 21 can cause the limiting notch 40 which is spliced with the limiting insert 42 to generate a pushing force on the limiting insert 42, so that the limiting insert 42 swings along the hinge position of the limiting insert and the deflector rod 41 in a direction away from the stop block 43, the rotation of the main filter plate 21 in the direction is not limited, the limiting insert 42 also enters into the other limiting notch 40 from one limiting notch 40, the elastic force of the first elastic piece is increased, the main filter plate 21 has a tendency to reversely rotate, and then the limiting notch 40 where the limiting insert 42 is located can give a swinging force to the limiting insert 42 in the direction of the hinge position of the limiting insert 42 and the deflector rod 41 towards the stop block 43, but the stop block 43 limits the swinging of the limiting insert 42, so that the reverse rotation of the main filter plate 21 is limited.

In the process that the filter holes on the main filter plate 21 and the filter holes on the auxiliary filter plate 22 are completely overlapped to be completely misaligned, on the premise that the wire block is in the process of approaching the static frame body 20, the trigger piece 33 can be in contact with the ejector rod 44 in advance, the trigger piece 33 pushes the ejector rod 44 to push the other end of the deflector rod 41, the other end of the deflector rod 41 can swing along the hinge joint of the deflector rod 41 and the static frame body 20 after being stressed, one end of the deflector rod 41 drives the limiting insert block 42 to be separated from the limiting notch 40, so that the reverse rotation of the main filter plate 21 is not limited, the filter holes on the main filter plate 21 and the filter holes on the auxiliary filter plate 22 are completely overlapped to be completely misaligned under the action of the resilience force of the first elastic piece, and in the process that the wire block is continuously approaching the static frame body 20 after being in the process, the trigger piece 33 can reversely squeeze the fourth elastic piece, the trigger piece 33 is retracted into the wire block, and the contact of the wire block and the static frame body 20 is not influenced.

The trigger member 33 has a rod-like structure, and the length of the trigger member can be set according to the amount of foam which enters the transition chamber 1 and cannot pass through the filter holes of the filter plate 30, so that the foam accumulated in the transition chamber 1 is prevented from being pushed back to the foaming tank when the filter plate 30 moves towards the auxiliary filter plate 22.

Because self preservation temperature building block becomes batch production, then filter 30 needs to reciprocate in transition chamber 1 many times, then stay cord 23 can appear using fatigue, and it just has the unable problem that resumes the former length after plastic elongation, then utilizes stay cord 23 to carry out spacing to main filter plate 21 just can appear the condition that the filtration pore on main filter plate 21 and the filtration pore on the vice filter plate 22 can not overlap completely.
