DETAILED DESCRIPTION

[0018] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0019] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.

[0020] Embodiment 1, as Figure 1 , 2As shown in Figures 3 and 4, a sintered thermal insulation block production equipment includes a roller conveyor line for conveying a sintered hollow thermal insulation block matrix j. The sintered hollow thermal insulation block matrix j in this embodiment refers to an thermal insulation block that is not filled with thermal insulation foaming material, such as an original thermal insulation block made of clay, shale, coal gangue or fly ash as raw materials, and is formed and high-temperature roasted. The sintered hollow thermal insulation block matrix j has a rectangular hollow hole j0 that runs through the upper and lower parts. In this embodiment, the sintered hollow thermal insulation block matrix j is placed lying like this, and the hollow hole j0 faces the upper and lower directions. The roller conveyor line includes conveying rollers 1 that are spaced apart at front and back intervals. The existing roller conveyor line can be used, mainly for conveying from front to back. Of course, it is not very good to directly convey the sintered hollow insulating block matrix j, and problems may easily occur. Therefore, the following configuration is performed in the embodiment: a loading mobile stacking frame k for loading the sintered hollow insulating block matrix j is provided on the roller conveyor line. A plurality of loading mobile stacking frames k can be provided and continuously placed on the conveying roller 1 for conveying. The loading mobile stacking frame k can load a lot of sintered hollow insulating block matrices j. The loading and moving stacking frame k can be made of steel. The loading and moving stacking frame k is preferably a rectangular box with an opening facing upward. Furthermore, a plurality of stacking grids k0 with openings facing upward can be formed on the loading and moving stacking frame k. The shape of the stacking grid k0 is designed according to the shape of the sintered hollow thermal insulation block matrix j. It can be square, round or special-shaped so that the sintered hollow thermal insulation block matrix j with matching appearance can be more stably limited after stacking. Furthermore, it is preferable that the stacking grids k0 are in a rectangular array on the loading and moving stacking frame k. In addition, the two sides of the roller conveyor line are preferably equipped with the existing left and right limiting guide wheels. The left and right limiting guide wheels respectively abut against the left and right sides of the loading and moving stacking frame k on the left and right sides to limit the loading and moving stacking frame k, so that the loading and moving stacking frame k can move straight from front to back, ensuring the walking accuracy and being more suitable for subsequent automatic equipment to carry out positioning and process implementation. In addition, an important design point of the present embodiment is that a delivery device for placing a thermal insulation reinforcement skeleton component into the hollow hole j0 of the sintered hollow thermal insulation block matrix j is provided on the conveying path of the roller conveyor line. That is, on the conveying path from front to back, the thermal insulation reinforcement skeleton component which serves as a structural reinforcement and thermal insulation material will be placed from top to bottom into the hollow hole j0 of the sintered hollow thermal insulation block matrix j, thereby filling the lack of structural strength of the hollow hole j0 and increasing the thermal insulation and sound insulation performance.Then, a foaming material injection device for injecting thermal insulation foaming material from top to bottom into the hollow hole of the sintered hollow thermal insulation block matrix j is also provided on the conveying path of the roller conveyor line, so that the foaming material can be filled into the hollow hole j0 and can also cover the aforementioned thermal insulation reinforcement skeleton component, so that there is both a thermal insulation support structure of the skeleton and a foam body filling structure after the foaming material is formed to fill the entire hollow hole j0, and the thermal insulation reinforcement skeleton component can be wrapped and hidden, and the foam body itself has good thermal insulation, heat insulation and sound insulation performance, and is also more beautiful, and the internal thermal insulation of the thermal insulation reinforcement skeleton component is also strengthened, and the overall effect will be better. The foaming material can be selected from existing polystyrene foam insulation materials, polyurethane foam insulation materials or phenolic foam insulation materials, etc., and these foaming materials can form good foam bodies after foaming and molding.

[0021] Preferably, a foaming loosening device for inserting a plurality of needles into the hollow holes of the sintered hollow thermal insulation block matrix j is provided on the conveying path of the roller conveyor line. The needles of the foaming loosening device are inserted from top to bottom into the foaming material layer that has been foamed for a period of time in the hollow holes of the sintered hollow thermal insulation block matrix j. The needles are round rod-shaped and pointed at the bottom. The diameter of the needle rod body is controlled at 3-6 mm. In this way, the formed foaming material layer is pierced by a plurality of needles to produce larger pores, which facilitates the subsequent foaming material to enter more quickly and evenly and has better connectivity, and the different foaming material layers between the upper and lower layers are better fused. The needle rods can be in a rectangular array.

[0022] Furthermore, the thermal insulation reinforcement skeleton assembly includes a lower reinforcement skeleton 21, a middle reinforcement skeleton 22 and an upper reinforcement skeleton 23 which are arranged in sequence from the lower side of the hollow hole j0 upward. The lower reinforcement skeleton 21, the middle reinforcement skeleton 22 and the upper reinforcement skeleton 23 have the same appearance. The hollow hole j0 is generally preferably rectangular. Therefore, taking the lower reinforcement skeleton 21 as an example, the lower reinforcement skeleton 21 is also preferably rectangular and its size should be as close to the hollow hole j0 as possible. This allows the lower reinforcement skeleton 21 to better fill and support the hollow hole j0. The other skeletons also have the same shape and size. Furthermore, the lower reinforcement skeleton 21 includes a rectangular outer frame 211 and a diamond-shaped inner frame 212 integrally connected to the outer frame 211. Here, the four corners of the inner frame 212 are preferably integrally connected to the middle points of the four sides of the outer frame 211. Such a structure is more regular and stable. Furthermore, the lower reinforcing frame 21, the middle reinforcing frame 22 and the upper reinforcing frame 23 are all thermal insulation plastic parts, which can be processed using existing thermal insulation plastics, but preferably the density of the lower reinforcing frame 21 and the density of the upper reinforcing frame 23 are both smaller than the density of the middle reinforcing frame 22, and the density of the lower reinforcing frame 21 and the density of the upper reinforcing frame 23 can be the same, so that the support in the middle is better and the stability of the overall structure is ensured. Furthermore, the thickness of the lower reinforcing frame 21 and the thickness of the upper reinforcing frame 23 are both smaller than the thickness of the middle reinforcing frame 22, and the thickness of the lower reinforcing frame 21 and the thickness of the upper reinforcing frame 23 can be the same, and the thickness of the middle reinforcing frame 22 is preferably controlled between one-fifth and one-third of the upper and lower thickness of the sintered hollow insulation block matrix j, and the thickness of the lower reinforcing frame 21 is preferably controlled between one-half and four-fifths of the thickness of the middle reinforcing frame 22.

[0023] The specific designs for each processing device are as follows: The foaming material spraying device includes four groups of foaming material spraying gun units which are separately arranged from front to back, namely a first foaming material spraying gun unit 31 , a second foaming material spraying gun unit 32 , a third foaming material spraying gun unit 33 and a fourth foaming material spraying gun unit 34 . Taking the first foaming material spray gun unit 31 as an example, the spray gun unit may include a spray gun moving beam 301 that can be lifted up and down and can be moved horizontally, and a plurality of foaming spray guns 302 that are installed and connected to the spray gun moving beam 301 and arranged horizontally on the left and right sides. The spray gun moving beam 301 can use the existing beam body, and the foaming spray gun 302 can use the existing foaming material spray gun. The spray gun moving beam 301 can be connected to an existing manipulator or an automatically controlled mobile device so as to move in a three-dimensional space. This design facilitates the foaming spray gun 302 to descend to spray the foaming material into the hollow hole j0 and return to its position, etc. The spacing of the foaming spray guns 302 and whether they need to be in a rectangular array can be designed accordingly according to the stacking form of the sintered hollow insulation block matrix j in the loading and moving stacking frame k, ensuring that the spray gun unit can simultaneously inject foaming materials into multiple insulation block matrices of the loading and moving stacking frame k. Other foaming material spray gun units can be designed with reference to the first foaming material spray gun unit 31.

[0024] The delivery device includes three groups of delivery units which are separately arranged from the front to the back, namely the first delivery unit 41, the second delivery unit 42 and the third delivery unit 43. The first delivery unit 41, the second delivery unit 42 and the third delivery unit 43 are used to deliver the lower reinforcement frame 21, the middle reinforcement frame 22 and the upper reinforcement frame 23 respectively. Taking the first delivery unit 41 as an example, the delivery unit may include a delivery moving beam 401 which can be lifted up and down and can be moved horizontally, and a plurality of reinforcement frame storage boxes 402 which are arranged horizontally on the left and right and are connected to the delivery moving beam 401. The delivery moving beam 401 may also adopt the existing beam body. The reinforcement frame storage box 402 may adopt the existing intelligent square material storage box, which has an intelligent opening on the lower side and an intelligent blocking structure inside, so that the reinforcement frames can fall down piece by piece and stop falling. Of course, the reinforcement frame storage box 402 may also use other existing clamping storage devices. The reinforcing frame can also be controlled to fall and stop piece by piece, and the delivery moving beam 401 can be connected to an existing manipulator or an automatically controlled mobile device so as to move in a three-dimensional space. This design facilitates the reinforcement frame storage box 402 to descend to the hollow hole j0 to deliver the reinforcement frame and return to its original position, etc. The spacing of the reinforcement frame storage box 402 and whether it needs to be in a rectangular array can be designed accordingly according to the stacking form of the sintered hollow insulation block matrix j in the loading and moving stacking frame k, ensuring that the delivery unit can deliver multiple insulation block matrices in the loading and moving stacking frame k at the same time. The other delivery units can be designed with reference to the first delivery unit 41.

[0025] Preferably, the first delivery unit 41, the second delivery unit 42 and the third delivery unit 43 are respectively located between two adjacent foaming material spray gun units from the front to the rear, that is, the first delivery unit 41 is located between the first foaming material spray gun unit 31 and the second foaming material spray gun unit 32, the second delivery unit 42 is located between the second foaming material spray gun unit 32 and the third foaming material spray gun unit 33, and the third delivery unit 43 is located between the third foaming material spray gun unit 33 and the fourth foaming material spray gun unit 34.

[0026] Furthermore, the foaming and loosening device includes three groups of foaming and loosening units which are separately arranged from front to back, namely a first foaming and loosening unit 51 , a second foaming and loosening unit 52 and a third foaming and loosening unit 53 . Taking the first foaming loosening unit 51 as an example, the foaming loosening unit may include a loosening moving beam 501 that can be lifted up and down and can move horizontally, and a plurality of needle plates 502 that are arranged horizontally on the left and right sides of the loosening moving beam 501. A plurality of needle rods 503 that are array-shaped and extend up and down are fixed to the lower side of the needle plate 502. The loosening moving beam 501 can use the existing beam body, and the needle plate 502 and the needle rod 503 can use the steel structure. The loosening moving beam 501 can be connected to the existing manipulator or the automatically controlled mobile device for movement in the three-dimensional space, so that the needle rod 503 can insert the needle into the hollow hole j0 for loosening and return to its position, etc. The spacing of the needle plates 502 and whether they need to be in a rectangular array can be designed accordingly according to the stacking form of the sintered hollow thermal insulation block matrix j in the loading mobile stacking frame k, so that the foaming loosening unit can perform the loosening operation of multiple thermal insulation blocks on one side. Other foaming loosening units can be designed with reference to the first foaming loosening unit 51.

[0027] Furthermore, the first foaming loosening unit 51 is located between the first delivery unit 41 and the second foaming material spraying gun unit 32, the second foaming loosening unit 52 is located between the second delivery unit 42 and the third foaming material spraying gun unit 33, and the third foaming loosening unit 53 is located between the third delivery unit 43 and the fourth foaming material spraying gun unit 34. This design has a better insulation block filling process, so the order of the units from front to back and separated is: the first foaming material spraying gun unit 31, the first delivery unit 41, the first foaming loosening unit 51, the second foaming The material spray gun unit 32, the second feeding unit 42, the second foaming loosening unit 52, the third foaming material spray gun unit 33, the third feeding unit 43, the third foaming loosening unit 53 and the fourth foaming material spray gun unit 34, through the orderly processing of these 10 units, the internal filling structure strength of the thermal insulation block is more stable and reliable, the thermal insulation, heat insulation and sound insulation effects are better, the production efficiency is also optimized, the controllability of the entire equipment is higher, which is very beneficial for high-quality production operations, and the quality of this thermal insulation block is improved, and the scope of use will be wider.

[0028] Embodiment 2, as Figure 5 , 6As shown in , 7, a sintered insulation block production process uses a sintered insulation block production equipment as in Example 1, including step 1: placing a sintered hollow insulation block matrix j into a loading and moving stacking frame k for stacking, and the hollow hole j0 of the sintered hollow insulation block matrix j extends in the up and down directions; step 2, placing the loading and moving stacking frame k containing the sintered hollow insulation block matrix j on a roller conveyor line for conveying from front to back; step 3, during the conveying process, specifically includes step 3.1: a first foaming material spray gun unit 31 performs a first foaming material spray filling and foaming molding on the sintered hollow insulation block matrix j to form a base foaming layer f1, and a corresponding foaming temperature control device needs to be set on the roller conveyor line. This method adopts the existing The device can be used, so the roller conveyor line speed can be kept relatively slow, so that the foaming material sprayed by the first foaming material can be effectively foamed and formed at the corresponding temperature, generally more than five minutes, so the left and right widths of the roller conveyor line in this embodiment can be larger, so that the number of thermal insulation blocks moving forward synchronously can be more and can be processed at the same time, and the subsequent operations can be carried out when the base foaming layer f1 is relatively solidified, and it is best not to wait for complete solidification, that is, step 3.2: the first delivery unit 41 delivers a lower reinforcing frame 21 on the upper side of the base foaming layer f1, and the lower reinforcing frame 21 will have gravity to be better laid flat, then step 3.3: the first foaming loosening unit 51 inserts needles to loosen the base foaming layer f1 in step 3.2 from top to bottom, The needle rod design here only needs to avoid the frame edge of the lower reinforcing frame 21, that is, do not insert it into the solid edge part of the lower reinforcing frame 21. After loosening, the flow uniformity and leveling of the subsequent foaming material will be improved, that is, the second foaming material spray gun unit 32 then performs a second foaming material spray filling and foaming molding on the sintered hollow insulation block matrix j to form a lower transition foaming layer f2 that submerges the lower reinforcing frame 21 upward. The lower transition foaming layer f2 will submerge the lower reinforcing frame 21 from the base foaming layer f1 upward and exceed the lower reinforcing frame 21, so that the lower reinforcing frame 21 is separated from the middle reinforcing frame 22. Of course, the lower transition foaming layer f2 also needs to be foamed and solidified for a period of time during the transportation process. Similarly, the same design as above is made The process steps of the design idea are used to place the middle reinforcement skeleton 22 and the upper reinforcement skeleton 23 and fill the foaming material, specifically: step 3.4: the second delivery unit 42 delivers a middle reinforcement skeleton 22 on the upper side of the lower transition foaming layer f2, step 3.5: the second foaming loosening unit 52 inserts needles to loosen the lower transition foaming layer f2 in step 3.4 from top to bottom, and then the third foaming material spray gun unit 33 sprays and fills the sintered hollow insulation block matrix j with foaming material for the third time and foams to form an upper transition foaming layer f3 that submerges the middle reinforcement skeleton 22 upward, step 3.6: the third delivery unit 43 delivers an upper reinforcement skeleton 23 on the upper side of the upper transition foaming layer f3, step 3.7: the third foaming loosening unit 53 performs step 3.6, the upper transition foaming layer f3 is loosened by inserting needles from top to bottom, and then the fourth foaming material spray gun unit 34 sprays and fills the sintered hollow thermal insulation block matrix j for the fourth time and foams to form a top foaming layer f4 that submerges the upper reinforcing skeleton 23 upward. Here, after the fourth foaming material spray filling, the existing cover plate placement equipment can be set on the conveying path, that is, a cover plate is placed on the side of many sintered hollow thermal insulation block matrices j to better perform foaming.

[0029] In addition, in order to prevent the bottom of the base foam layer f1 and the bottom of the stacking grid k0 where the loading and moving stacking frame k is located from sticking together, a smooth plastic film can be laid at the bottom of the stacking grid k0, so that the thermal insulation blocks will not stick to the stacking frame during production, and it is also convenient to tear off the thermal insulation blocks after production. Of course, they can also be used together without tearing them off. Of course, a large plastic film can be used to lay on the upper side of the entire loading and moving stacking frame k. When the sintered hollow thermal insulation block matrix j is placed in the stacking grid k0, the plastic film will automatically be pressed into the corresponding stacking grid k0.

[0030] The thermal insulation blocks produced by the above process will be efficient and high-quality.

[0031] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present invention, and these modifications or replacements should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope of the claims.
