DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-4 As shown, a permeable brick casting and molding device includes a top plate 7, a bottom plate 1, and a conical mold 5 located between the top plate 7 and the bottom plate 1 and having an opening 17 in the circumferential direction. The opening 17 of the conical mold 5 is set from the upper end surface to the lower end surface of the conical mold 5. Figure 3 As shown, the purpose of setting the opening 17 on the side of the conical mold 5 is to facilitate the first plastic strip 3 to make way during the winding process so that the first plastic strip 3 can be completely located inside the conical mold 5 after the winding is completed.

[0022] A plurality of slots 15 are provided at the surface edge positions of the top plate 7 and the bottom plate 1. In this example, there are 6 slots 15 on the top plate 7 and the bottom plate 1 respectively, and the slots 15 are evenly distributed around the center of the top plate 7 and the bottom plate 1. The purpose of providing the slots 15 is to enable the first plastic strip 3 to quickly enter the root position of the slot 15 to replace the existing perforation method, which has the advantages of simple operation and high work efficiency.

[0023] The top plate 7 and the bottom plate 1 have cylindrical heads 16 at their outer end surfaces, the same number as the slots 15. The cylindrical heads 16 are installed between two adjacent slots 15 and close to the center of the top plate 7 and the bottom plate 1. The first plastic strip 3 is wrapped around the slots 15 of the top plate 7 and the bottom plate 1. The cylindrical heads 16 can serve as positioning pieces for the first plastic strip 3, so that the first plastic strip 3 can be tightly attached to the root of the slot 15, thereby achieving a precise positioning effect.

[0024] The first plastic strip 3 can extend outward from the slots 15 of the bottom plate 1 and the top plate 7 , bypass the adjacent cylindrical head 16 and enter the slots 15 at the adjacent position, so that the first plastic strip 3 is wound around the slots 15 of the top plate 7 and the bottom plate 1 .

[0025] An upper blocking ring 10 and a lower blocking ring 2 are detachably installed at the outer end surfaces of the top plate 7 and the bottom plate 1. The surfaces of the upper blocking ring 10 and the lower blocking ring 2 are provided with a blocking piece 19 protruding outward and capable of extending into the groove 15. The thickness of the blocking piece 19 is the same as the width of the top plate 7 and the groove 15 on the top plate 7. The upper blocking ring 10 and the lower blocking ring 2 are mainly designed to seal the groove 15 opened on the top plate 7 and the bottom plate 1. Among them, the main sealing range only needs to ensure that there will be no leakage during pouring, so as to meet the molding process of the breathable brick.

[0026] The conical mold 5 is provided with a sealing plate 18 for sealing the opening 17. Since the opening 17 of the conical mold 5 is for giving way, after the first plastic strip 3 is wound, the opening 17 of the conical mold 5 is sealed with the sealing plate 18 to meet the final forming of the air-permeable brick.

[0027] A screw sleeve 8 is threadedly connected to the middle position of the surface of the top plate 7, a baffle 9 is installed above the screw sleeve 8, a second plastic strip 6 is connected to the baffle 9, a silicon carbide rod 4 is connected to the middle position of the second plastic strip 6, the lower end of the second plastic strip 6 passes through the bottom plate 1 and is connected to the baffle 9 below the bottom plate 1. This part of the structure is mainly used to place the silicon carbide rod 4 in the center of the mold, so that during the production and use of the air-permeable brick, the silicon carbide rod 4 can be used to check the corrosion position of the air-permeable brick to play a warning effect, wherein the lower end of the second plastic strip 6 passes through the center of the bottom plate 1 in a perforated manner, and the baffle 9 is used as a limiter, the upper end is connected to the baffle 9 above, and the screw sleeve 8 is used to drive the baffle 9 to move upward, so as to straighten the second plastic strip 6.

[0028] The edges of the top plate 7 and the bottom plate 1 are both provided with extension sections 13 extending outward, through holes 12 are provided on the two extension sections 13 and screws 11 are passed through them. Such arrangement is to enable the top plate 7 and the bottom plate 7 to rotate synchronously during the winding process of the first plastic strip 3 to avoid the problem of relative rotation, and also to ensure that the first plastic strip 3 will not be twisted inside the conical mold 5.

[0029] The upper surface of the bottom plate 1 has a limit strip 14 that protrudes upward and is evenly distributed around the center of the bottom plate 1. There are three limit strips 14, and the inner wall fits with the conical mold 5, which makes it easy to make the top plate 7, the bottom plate 1 and the center of the conical mold 5 coaxial when winding the first plastic strip 3. At the same time, there will be no interference problem when the sealing plate 18 is installed on the conical mold 5.

[0030] The cross-sectional shape of the lower surface of the top plate 7 is an arc structure, and there is a stopper structure between the top plate 7 and the conical mold 5. On the one hand, it is for positioning, and on the other hand, the lower surface of the arc structure can be used to make the upper part of the formed air-permeable brick concave.

[0031] When this breathable brick casting and molding equipment is in use, the second plastic strip 6 is first passed through the center of the bottom plate 1 and limited by the baffle 9. The upper end of the second plastic strip 6 passes through the center of the screw sleeve 8 and is connected to the baffle 9. At this time, the second plastic strip 6 does not need to be straightened; then the top plate 7 and the bottom plate 1 are placed on the upper and lower ends of the conical mold 5 respectively, so that the extension sections 13 at the edges of the top plate 7 and the bottom plate 1 are aligned, and the screw rod 11 is passed through the through holes 12 of the two extension sections 13, and the nut is installed on the screw rod 11, and the nut is in an unpretightened state.

[0032] After that, the first plastic strip 3 can be wound. First, the first plastic strip 3 is fixed on the cylindrical head 16 outside the top plate 7, and then the first plastic strip 3 passes through the slot 15 adjacent to the cylindrical head 16, enters the conical mold 5 in accordance with the notch of the conical mold 5, and passes through the slot 15 of the bottom plate 1, and then bypasses the cylindrical head 16 on the bottom plate 1 and enters the second slot 15 of the bottom plate 1, and then returns to the top plate 7 position, and repeats this process, and the first plastic strip 3 can be wound around the top plate 7 and the bottom plate 1. When the winding work is completed, , install the upper blocking ring 10, the lower blocking ring 2 and the sealing plate 18 to the top plate 7, the bottom plate 1 and the conical mold 5 in turn, at this time, straighten the first plastic strip 3 and fix it on the cylindrical head 16, straighten the second plastic strip 6 (rotate the screw sleeve 8 to straighten it), tighten the nut on the screw 11, and finally fix the top plate 7 and the bottom plate 1 on the conical mold 5 with screws respectively. After completing the whole operation process, the staff can pour the slurry into the conical mold 5 along the center of the screw sleeve 8, and then form the air-permeable brick after demoulding and firing.
