[0023] Please refer to Figs. 1-3 An efficient and easy-to-release sludge sintering frame, comprising an outer frame 1, a base 2, and an inner partition plate 3, the outer frame 1 is a rectangular frame with an upper and lower opening surrounded by four side walls, the base 2 is detachably installed at the bottom opening of the outer frame 1, the outer frame 1 and the base 2 are combined to form an upper opening accommodating cavity 4, and the inner partition plate 3 is detachably installed inside the accommodating cavity 4; the outer frame 1, the base 2 and the inner partition plate 3 are all made of plate material with sieve holes 5, the top surface of the outer frame 1 is provided with triangular plates 6 at four corners, and the two edges of the triangular plate 6 are connected with the two adjacent side walls respectively.

[0024] The function of the sludge sintering frame is to sinter and dry the sludge with high water content to form sludge bricks; the sludge bricks are taken out and broken, and then mixed with raw materials such as yellow sand and concrete to be sintered again to form concrete bricks for final use. The structure of the sludge sintering frame is improved to improve the sintering efficiency of the sludge sintering frame and reduce the difficulty of the sludge sintering frame after sintering.

[0025] The utility model discloses a sludge sintering frame, set up between the outer frame 1 and base 2 into detachable mounting structure, when using, first install base 2 at the bottom of outer frame 1, then set up the partition plate in outer frame 1, after installing, pour the sludge into sludge sintering frame and send into the tunnel kiln and carry out sintering. First, in order to improve the strength, set up the triangular plate 6 at the top of outer frame 1, but the triangular plate 6 will hinder the sludge brick after sintering from the sintering frame to some extent, and the utility model discloses that the outer frame 1 and base 2 are detachable structure, can be detached from the outer frame 1 after sintering is completed, so that the top and bottom of outer frame 1 are all open, greatly reduce the difficulty of sludge brick from sludge sintering frame. Secondly, set up the inner partition plate 3 in the inside of outer frame body, after combining with base 2, can divide the accommodation cavity 4 into multiple small chambers, so that when the accommodation cavity 4 is filled with sludge and sintered, the sludge can be separated in multiple small chambers by the inner partition plate 3, can make the sludge get more uniform, more efficient sintering effect. Finally, the outer frame body, base 2, inner partition plate 3 are all by the plate material with sieve hole 5 composition, therefore when the sludge is put into the sintering frame, the moisture in it can overflow from the sieve hole 5 under the extrusion and filtration effect, and the moisture of sintering can evaporate from the sieve hole 5 quickly, effectively improve the sintering efficiency.

[0026] In some embodiments, the edges formed by the intersection of every two inner side walls of the outer frame 1 are provided with support angle irons 7, and the two sides of each support angle iron 7 are connected with the two side walls adjacent thereto; further, a cavity with a triangular cross section is formed between each support angle iron 7 and the two side walls adjacent thereto. The support angle irons 7 serve to improve the support strength of the outer frame 1, so that the outer frame 1 can withstand multiple sintering without deformation, and the support angle irons 7 can also shield the right-angle corners formed by the intersection of every two side walls, so that the intersection of the side walls becomes an obtuse angle or even a rounded corner, which can facilitate the sludge sintering frame to be taken out more conveniently and quickly.

[0027] In some embodiments, the base 2 is clamped and fixed with the bottom of the outer frame 1 and locked by a locking structure; a clamping groove can be arranged on the bottom of the outer frame 1, and a clamping block can be arranged on the periphery of the base 2, so that when the base 2 is installed on the bottom of the outer frame 1, the clamping block of the base 2 is clamped in the clamping groove of the bottom of the outer frame 1, thereby realizing the fixation between the base 2 and the outer frame 1. The locking structure can be a buckle, a locking screw or other mechanical locking structure, which further ensures the fixation effect between the base 2 and the outer frame 1 and avoids the base 2 from falling off the outer frame 1 during sintering and transportation.

[0028] In some embodiments, a handle 8 is arranged on the outer side of the base 2 away from the accommodating cavity 4, facilitating workers to take the base 2 off the outer frame 1 through the handle 8. In some further embodiments, the handle 8 is arranged inwardly in the base 2, and the highest point of the handle 8 does not exceed the outer side of the base 2 where the handle 8 is arranged, so that the sludge sintering frame can be placed on a horizontal plane without shaking due to the protrusion of the handle 8, which is beneficial to sludge sintering. The handle 8 can be arranged in an inwardly recessed operation part arranged on the outer side of the base 2, so as not to exceed the horizontal plane of the base 2.

[0029] In some embodiments, one side of the base 2 inside the accommodating cavity 4 is provided with a partition strip 21 corresponding to the length, mounting direction and mounting position of the inner partition plate 3, and when the base 2 is mounted at the bottom of the outer frame 1, the partition strip 21 is connected with the inner partition plate 3 and divides the accommodating cavity 4 into several small chambers. The partition strip 21 can be integrally connected with the base 2, or can be connected by welding, threaded connection, clamping and the like. The partition strip 21 and the inner partition plate 3 combine to divide the accommodating cavity 4, which aims to improve the sludge sintering efficiency, improve the sludge sintering uniformity and improve the sludge sintering quality.

[0030] Further, the number of the partition plate and the partition strip 21 can be one, two or more, and the direction can be arbitrarily mounted along the length direction or the width direction of the sintering frame according to actual needs.

[0031] In some embodiments, the inner partition plate 3 is mounted in the outer frame 1 by clamping fixation, which can be that the corresponding position inside the outer frame 1 is provided with a limiting groove, and the inner partition plate 3 is inserted and fixed in the limiting groove, or the joint between the outer frame 1 and the inner partition plate 3 is fixed by clamping buckle, which is convenient to install and quickly limits, and can be quickly docked with the inner partition strip of the base 2.

[0032] In some embodiments, the outer frame 1 is prepared by overlapping multiple layers of plates, and the positions of the screen holes 5 of the multiple layers of plates do not correspond to each other, which effectively avoids the overflow of sludge with high water content and low particles from the screen holes 5 of the outer frame 1, filters water while retaining the amount of sludge.
