Abstract
Description
Technical Field
[0001] This utility model relates to the field of sludge brick making technology, and in particular to a firing box for sludge brick making. Background Technology
[0002] With the continuous increase in urban sewage treatment volume, the amount of sludge generated is also growing larger. Using sludge for brick making is one of the effective ways to realize the resource utilization of sludge. In the process of sludge brick making, firing is a key step, and the performance of the firing box directly affects the quality of bricks and production efficiency.
[0003] Chinese Patent 202421634365.5 discloses an environmentally friendly sludge firing box for making bricks from sludge. The box includes a body with a square frame at the top. The four corners of the square frame are connected to the four corners of the box via support rods. The upper edge of the square frame and the inner lower edge of the box are chamfered. The side walls of the box have several ventilation holes and ventilation grooves. The bottom plate of the box has several through grooves and several ventilation holes. Limiting plates are connected to the four corners of the lower end of the box. The advantages of this invention are: high stacking stability, large firing area, and good uniform firing effect.
[0004] However, when using the aforementioned firing box, the sludge-made brick blanks need to be neatly stacked inside the box. These neatly stacked brick blanks will come into contact with each other. Because the brick blanks are tightly packed inside the box, they form a heat conduction barrier. When placed in a high-temperature environment, the brick blanks on the outside of the box, being in direct contact with the heat source, can quickly absorb heat. However, the brick blanks in the middle of the box, being surrounded by other brick blanks, have significantly reduced heat transfer efficiency. This significant temperature gradient may lead to inconsistent firing processes among the brick blanks inside the box, causing the middle brick blanks to be underfired and lack strength, while the outer brick blanks may be overfired, resulting in a loose structure. This affects the overall quality and production efficiency of sludge-made bricks. Therefore, a sludge-made brick firing box is proposed to solve these problems. Utility Model Content
[0005] (a) Purpose of the utility model
[0006] To address the technical problems existing in the background art, this utility model proposes a firing box for sludge brick making, which solves the problem of uneven firing of brick blanks in the prior art and improves the quality and production efficiency of sludge brick making.
[0007] (II) Technical Solution
[0008] This utility model provides a firing box for sludge brick making, including an upper outer frame, a lower outer frame and a U-shaped side outer frame. The bottom of the upper outer frame is connected to the lower outer frame through the side outer frame. Multiple horizontal base plates are equidistantly arranged on the inner wall of the side outer frame along the height direction. The base plates are slidably connected to the placement mechanism through spaced sliding components.
[0009] The placement mechanism includes a placement base, a connecting outer frame, and connecting support plates. The bottom of the placement base is slidably engaged with the base plate through the sliding component. The upper edge of the placement base is fixedly connected to the connecting outer frame through the circumferentially distributed connecting support plates. The upper surface of the placement base is provided with a grid-type divider for separating brick blanks.
[0010] Preferably, each of the base plates has a through groove located between multiple adjacent sliding components.
[0011] Preferably, the sliding component includes a sliding groove formed on the upper surface of the base plate and limiting grooves symmetrically formed on both sides of the sliding groove, and the bottom of the placement base is provided with limiting support feet that slide in cooperation with the multiple limiting grooves.
[0012] Preferably, the grid-type divider includes a plurality of first limiting plates and a plurality of second limiting plates arranged orthogonally. The plurality of first limiting plates and the plurality of second limiting plates are installed between the upper inner wall of the placement base. The plurality of first limiting plates and the plurality of second limiting plates intersect to form a matrix placement groove. The bottom of the placement groove is provided with a plurality of through holes penetrating the placement base.
[0013] Preferably, the depth of the limiting groove is less than the height of the limiting support foot.
[0014] Preferably, the distance between two adjacent base plates is greater than the total height of the placement mechanism, which is the sum of the heights of the placement base, connecting support plate, connecting outer frame, and limiting support foot.
[0015] Preferably, the outer wall of the side frame has a plurality of first slots that communicate with the interior evenly distributed along the height direction, and the first slots are rectangular through-hole structures.

[0018] 1. The sludge brick-making firing box uses a separator to separate the brick blanks into independent placement slots, avoiding direct contact between multiple brick blanks. Furthermore, the spacing between adjacent bottom plates is designed to be greater than the total height of the placement mechanism, allowing hot air to flow between the sludge brick blanks, significantly improving heat transfer efficiency, solving the problem of uneven brick blank firing in existing technologies, and improving the quality and production efficiency of sludge bricks.
[0019] 2. The sludge brick-making firing box has a detachable positioning fit between the limiting hole at the top of the upper outer frame and the limiting support at the bottom of the lower outer frame, which facilitates the stacking of multiple firing boxes and improves space utilization.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0030] like Figure 1-6 As shown, the present invention proposes a sludge brick-making firing box, which includes an upper outer frame 1, a lower outer frame 5 and a U-shaped side outer frame 3. The bottom of the upper outer frame 1 is connected to the lower outer frame 5 through the side outer frame 3. Multiple horizontal bottom plates 8 are equidistantly arranged on the inner wall of the side outer frame 3 along the height direction. The bottom plates 8 are slidably connected to the placement mechanism through spaced sliding components.
[0031] The placement mechanism includes a placement base 11, a connecting outer frame 9, and a connecting support plate 10. The bottom of the placement base 11 is slidably engaged with the base plate 8 through a sliding component. The upper edge of the placement base 11 is fixedly connected to the connecting outer frame 9 through the circumferentially distributed connecting support plates 10. The upper surface of the placement base 11 is provided with a grid-type partition for separating brick blanks. One of the placement bases 11 can only hold one layer of sludge brick blanks.
[0032] In this utility model, when in use, the sludge brick blank is placed in multiple placement slots 17, and then the placement mechanism containing the sludge brick blank is pushed into the base plate 8 through the sliding component, and then the side frame 3 containing the sludge brick blank is placed in the firing equipment or firing space.
[0033] During the firing process, the external hot air generated by the firing equipment or firing space enters the placement mechanism through the first slot 2, and some of the hot air enters the lower space through the through slot 13. At the same time, the connecting hole 14 allows the hot air to penetrate the bottom of the brick blank. Since the brick blank is independently supported by the partition frame, the heat conduction barrier caused by mutual contact is avoided, which significantly improves the firing uniformity.
[0034] Hot air passes through the gap between the connecting support plates 10, allowing the hot air to fire the sides of the sludge brick blank.
[0035] In an optional embodiment, the base plate 8 is provided with through slots 13 located between multiple adjacent sliding components.
[0036] It should be noted that the through groove 13 can better transfer external heat to the placement base 11.
[0037] In an optional embodiment, the sliding assembly includes a sliding groove 7 formed on the upper surface of the base plate 8 and limiting grooves 12 symmetrically formed on both sides of the sliding groove 7. The bottom of the base 11 is provided with limiting support feet 18 that slide in cooperation with the multiple limiting grooves 12. The depth of the limiting grooves 12 is less than the height of the limiting support feet 18. The limiting support feet 18 are trapezoidal, and the inclined surface of the limiting support feet 18 faces the side of the opening of the side frame 3.
[0038] It should be noted that the depth of the limiting groove 12 is less than the height of the limiting support foot 18. This structural design enables the placement base 11 to have guiding and positioning functions during installation.
[0039] The specific operating procedure is as follows:
[0040] When it is necessary to slide the placement base 11 into the base plate 8, first align the limiting support foot 18 at the bottom of the placement base 11 with the sliding groove 7, so that the placement base 11 is slidably installed on the base plate 8. Then the limiting support foot 18 at the bottom of the placement base 11 will slide along the axis of the sliding groove 7. When the placement base 11 reaches the predetermined position, the limiting support foot 18 is just aligned with the limiting groove 12 and locked in. At this time, the limiting groove 12 forms a certain constraint force on the limiting support foot 18, which can prevent the placement base 11 from shifting to a certain extent.
[0041] When an outward pulling force is applied, due to the trapezoidal structure design of the limiting support foot 18, its hypotenuse forms a guiding fit with the inlet of the sliding groove 7, so that the limiting support foot 18 can be disengaged from the limiting groove 12 without additional operation, making it easy to remove the placement base 11.
[0042] When it is necessary to slide the placement base 11 onto the base plate 8, the operator needs to slide the multiple limiting support feet 18 near the inner side of the bottom of the placement base 11 into the sliding groove 7 located between the limiting grooves 12 on both sides, and then push the placement base 11.
[0043] In an optional embodiment, the grid-type divider includes a plurality of first limiting plates 15 and a plurality of second limiting plates 16 arranged orthogonally. The plurality of first limiting plates 15 and the plurality of second limiting plates 16 are installed between the upper inner wall of the placement base 11. The plurality of first limiting plates 15 and the plurality of second limiting plates 16 intersect to form a matrix placement groove 17. The bottom of the placement groove 17 is provided with a plurality of connecting holes 14 penetrating the placement base 11.
[0044] It should be noted that the partition frame on the upper surface of the placement base 11 is composed of multiple first limiting plates 15 and multiple second limiting plates 16 arranged orthogonally to form a matrix placement groove 17. Each placement groove 17 has a connecting hole 14 with a diameter of 3-5mm evenly distributed at the bottom for hot air to penetrate the bottom of the brick blank.
[0045] In an optional embodiment, the distance between two adjacent base plates 8 is greater than the total height of the placement mechanism, which is the sum of the heights of the placement base 11, the connecting support plate 10, the connecting outer frame 9, and the limiting support foot 18.
[0046] It should be noted that this ensures that the placement mechanism can slide out from the two adjacent base plates 8 via the sliding components.
[0047] In an optional embodiment, the outer wall of the side frame 3 has a plurality of first slots 2 that communicate with the interior evenly distributed along the height direction. The first slots 2 are rectangular through holes.
[0048] It should be noted that rectangular first slots 2 are evenly distributed along the height direction on the outer wall of the side frame 3, which are used to introduce external heat and exhaust moisture.
[0049] In an optional embodiment, the upper outer frame 1 is provided with limit holes 6 at the top four corners, and the lower outer frame 5 is provided with limit feet 4 at the bottom four corners that are adapted to the limit holes 6. The limit feet 4 and the limit holes 6 form a detachable positioning fit.
[0050] It should be noted that the limiting holes 6 at the top four corners of the upper outer frame 1 and the limiting feet 4 at the bottom of the lower outer frame 5 form a plug-in positioning fit. The outer diameter of the limiting feet 4 is 2mm smaller than the inner diameter of the limiting holes 6 to ensure stability during stacking.
[0051] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
