[0019] 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. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0020] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0021] like Figure 1 The filter cake calcining device shown includes a device body 100, the device body 100 includes a bracket 1 and a combustion box 2, a conveying mechanism 3 is installed on the bracket 1, and the output end of the conveying mechanism 3 is connected to the combustion box 2;

[0022] The filter cake is delivered to the combustion box through the conveying mechanism. During the conveying process, the filter cake can be squeezed to break the filter cake, thereby improving the subsequent combustion efficiency entering the combustion box.

[0023] The combustion box 2 is tiltedly arranged at the output end of the conveying mechanism, an exhaust port 5 is formed on the top of the combustion box 2, and a telescopic mechanism 6 is installed at the bottom of the combustion box 2. The telescopic mechanism 6 crushes and turns the filter cake entering the combustion box to promote full combustion of the filter cake;

[0024] In order to facilitate the filter cake to quickly enter the combustion box, the combustion box is tilted, and the input end of the screw conveyor 32 is inserted between the upper layer and the lower layer of the combustion box. The filter cake conveyed by the screw conveyor can quickly enter the combustion box. After the filter cake enters the combustion box, the filter cake is turned over by the up and down movement of the telescopic mechanism to speed up the combustion efficiency.

[0025] In one embodiment, the combustion box 2 is divided into a conical upper layer and a lower layer connected to the upper layer, the exhaust port 5 is located at the top of the upper layer, and a telescopic mechanism 6 is installed in the lower layer.

[0026] In order to facilitate the filter cake to enter the combustion box and turn over the filter cake, the combustion box is tilted so that the filter cake can slide along the bottom of the combustion box and cover the bottom of the box instead of piling up in one place. The filter cake can be evenly dispersed on the bottom of the combustion box. Combined with the movement of the telescopic mechanism, the filter cake can be turned over and evenly covered on the bottom of the combustion box, thereby promoting calcination efficiency.

[0027] In one embodiment, the conveying mechanism 3 includes a motor 31 and a screw conveyor 32 . The output shaft of the motor 31 is connected to the screw conveyor 32 . The top of the screw conveyor 32 is connected to a feed port 4 .

[0028] Add the filter cake through the feed port, start the motor, and drive the screw conveyor to work, so as to realize the conveying of the filter cake, and squeeze the filter cake during the conveying process to facilitate the subsequent calcination.

[0029] like Figure 2 As shown, the telescopic mechanism 6 includes a plurality of hydraulic cylinders 61 and a push rod 62 connected to the output end of the hydraulic cylinder 61. The free end of the push rod 62 penetrates the bottom of the lower layer of the combustion box 2 and extends upward.

[0030] Start the hydraulic cylinder, which drives the push rod to move up and down. During the extension and retraction process, the push rod flips the filter cake at the bottom of the combustion box, making the filter cake more evenly distributed and the combustion more complete.

[0031] In order to make the filter cake flip evenly, the push rods are arranged in a straight line, and the centers of all the push rods are located on the same horizontal line, so that the filter cake can be evenly distributed after flipping. Specifically, a plurality of hydraulic cylinders 61 are arranged at equal intervals, and the fixing frame 7 is connected to the bracket at an angle. The hydraulic cylinders 61 are arranged on the fixing frame in a straight line from top to bottom, and the hydraulic cylinders 61 are perpendicular to the horizontal plane. The push rods 62 are perpendicular to the bottom surface of the lower layer of the combustion box 2. The fixing frame 7 and the bottom surface of the lower layer of the combustion box 2 are parallel to each other.

[0032] In one embodiment, a gas pipe 21 is provided on the upper cover of the combustion box 2, and a nozzle 22 is connected to the gas pipe 21. Gas can be introduced through the gas pipe, sprayed out from the nozzle, and ignited by an ignition device (not shown), thereby performing calcination.

[0033] The working process of the utility model is as follows: the filter cake is transported to the combustion box through the screw conveyor, and the push rod is pushed up and down to realize the turning or breaking of the filter cake through the control of the hydraulic cylinder, so as to promote the full combustion of the filter cake.

[0034] The utility model aims to provide a filter cake calcining device, which is used to improve the mixing effect of the filter cake, thereby improving the combustion of the filter cake, and turning the filter cake through a telescopic mechanism to ensure the combustion efficiency of the filter cake.

[0035] The above implementation modes are not limitations of the present invention, and the present invention is not limited to the above examples.
