In the sludge treatment process, sludge drying is a key link, and its efficiency and quality are directly related to the success or failure of the entire treatment process.

[0003] Patent Publication (Announcement) No.: CN219637080U, discloses a box-type closed sludge low-temperature dryer, which loads wet sludge into a sludge loading box and transports it to a drying chamber by a forklift, then closes the drying chamber door and locks it with a box-type door lock assembly, and dehumidifies and reduces the volume by a heat pump system and a main fan. The sludge loading box is provided with openings at the top and bottom, and a mesh plate is provided at the bottom opening. This design results in the bottom of the box being a plane, and during the drying process, the airflow dries the sludge accumulated in the middle of the box at a slower speed, and since the wind cannot directly reach the middle part of the box, part of the sludge cannot be fully dried, affecting the drying effect. Therefore, it is necessary to design a drying hopper with a faster drying speed and more uniform drying. Utility Model Content

[0005] The purpose of the present application is to provide a drying hopper of a chamber-type sludge dryer. By arranging a hollow partition mesh plate in the center of the drying hopper, the hot air entering the drying hopper from below can not only contact the sludge on the surface, but also directly enter the center of the drying hopper from the partition mesh plate. In this way, the hot air can enter the interior of the drying hopper from the partition mesh plate for drying, thereby improving the drying effect and avoiding uneven drying.

[0006] In order to achieve the above purpose, this application adopts the following technical solutions:

[0008] Furthermore, the base is provided with two conveying holes, the distance between the two conveying holes is greater than the length of the discharge port, and the two conveying holes are axially symmetrical through the center line of the base.

[0009] Furthermore, the funnel mesh plate is composed of four inclined mesh plates, each of which is trapezoidal, one side of the inclined mesh plate is fixedly connected to the inner wall of the box, the side of the side mesh plate away from the inner wall of the box is fixedly connected to the discharge port, and the four adjacent inclined mesh plates are fixedly connected to each other.

[0010] Furthermore, the limiting structure includes: a limiting block, a rotating unloading rod and a handle, the limiting block is in the shape of a long strip, one end of the limiting block is fixedly connected to the rotating unloading rod, the limiting block is away from the end of the rotating unloading rod to block the unloading plate, connecting plates are provided on both sides of the discharge port, circular through holes are provided on the connecting plates, one end of the rotating unloading rod passes through the circular through holes of the side surface of the base and the connecting plate, and the end of the rotating unloading rod located outside the base is fixedly connected to the handle.

[0025] The present application is further described below in conjunction with the accompanying drawings and embodiments. Example 1

[0026] A drying hopper of a box-type sludge drying machine, such as Figure 1-6 As shown, it includes: a base 1 and a discharge plate 11, the base 1 is a rectangular frame, a box body 2 with upper and lower openings is arranged above the base 1, the box body 2 is a hollow rectangular parallelepiped, a funnel mesh plate 4 is arranged at one end of the box body 2 close to the base 1, a discharge port 10 is arranged at one end of the funnel mesh plate 4 close to the base 1, the discharge plate 11 is connected to the discharge port 10 by a hinge 12, a limiting structure is arranged at one end of the discharge plate 11 away from the hinge 12, and the switch of the discharge port 10 is controlled by the limiting structure, a partition mesh plate 5 is also arranged in the center of the funnel mesh plate 4, the partition mesh plate 5 is a hollow structure, the partition mesh plate 5 and the discharge port 10 are perpendicular to each other, the funnel is divided into two parts by the partition mesh plate 5, and ventilation is also convenient.

[0027] like Figure 1 As shown, the base 1 is provided with a transport hole 3, and there are two transport holes 3. The distance between the two transport holes 3 is greater than the length of the discharge port. The two transport holes 3 are axially symmetrical through the center line of the base 1, and are moved by inserting the fork teeth of a forklift into the transport hole 3.

[0028] like Figure 2As shown, the funnel mesh plate 4 is composed of four inclined mesh plates, which are trapezoidal. One side of the inclined mesh plate is fixedly connected to the inner wall of the box body 2, and the side of the side mesh plate away from the inner wall of the box body 2 is fixedly connected to the discharge port 10. The four adjacent inclined mesh plates are fixedly connected to each other, and finally the four inclined mesh plates form a funnel shape with an opening at the bottom.

[0029] like Figure 2-3 As shown, the limiting structure includes: a limiting stopper 13, a rotating unloading rod 7 and a handle 8. The limiting stopper 13 is in the shape of an elongated strip, one end of which is fixedly connected to the rotating unloading rod 7, and the end of the limiting stopper 13 away from the rotating unloading rod 7 blocks the unloading plate 11. Connecting plates 14 are provided on both sides of the discharge port 10, and circular through holes are provided on the connecting plates 14. One end of the rotating unloading rod 7 passes through the circular through holes of the side surface of the base 1 and the connecting plate 14, and the end of the rotating unloading rod 7 located outside the base 1 is fixedly connected to the handle 8. The rotating unloading rod 7 is rotated by the handle 8 to drive the limiting stopper 13 to rotate, and the limiting stopper 13 is away from the unloading plate 11 to open the unloading plate 11.

[0030] like Figure 2-4 As shown, a baffle plate 9 is further provided at one end of the base 1 close to the handle 8, and the baffle plate 9 is rotatably connected to the base 1 by bolts and nuts. The baffle plate 9 blocks the rotation of the handle 8, so that the unloading plate 11 can be fixed on the discharge port 10. When the unloading plate 11 needs to be opened, the baffle plate 9 is rotated to make the baffle plate 9 leave the blocking range of the handle 8, so that the handle 8 can be rotated to drive the limit stopper 13 to leave the unloading plate 11, and the unloading plate 11 is opened to facilitate unloading.

[0031] like Figure 5 As shown, the partition mesh plate 5 is an inverted trapezoidal shape that is wide at the top and narrow at the bottom.

[0032] like Figure 1 As shown, the side of the box body 2 is further provided with reinforcing ribs 6 , and the reinforcing ribs 6 are cross-shaped reinforcing ribs 6 , and the reinforcing ribs 6 provide supporting strength for the box body 2 .

[0033] The discharge plate 11, the funnel mesh plate 4 and the partition mesh plate 5 are all provided with evenly distributed air holes to facilitate hot air to enter therein for drying.

[0034] When the sludge is transported to the drying hopper, the fork tines of the forklift are inserted into the transport holes 3 of the base 1, and the drying hopper is transported to the box-type sludge dryer 16 by the forklift. Figure 6As shown, the circulating fan 15 is turned on, and the dry hot air enters the drying hopper from the discharge plate 11 at the bottom of the drying hopper and the mesh holes of the funnel mesh plate 4, so that the sludge in the drying hopper can be dried. The partition mesh plate 5 in the drying hopper can also serve as a transmission channel for hot air, so as to prevent the sludge accumulated in the center of the drying hopper from being unable to dry, thereby improving the drying efficiency and uniformity of the sludge, and avoiding incomplete drying of the sludge in the center of the drying hopper. The dry hot air exchanges heat with the wet sludge to bring out the moisture in the wet sludge. At this time, what comes out of the drying hopper is the humid hot air, and the dust in the humid hot air is filtered through the filter. The filtered humid hot air is cooled and dehumidified by the heat regenerator and the surface cooler to obtain dry cold air. The dry cold air is heated by the heater and then enters the circulating fan 15 as the dry hot air, and the dry hot air is sent to the drying hopper through the air supply port of the circulating fan 15, and circulated continuously to finally dry the wet sludge in the drying hopper, thus achieving the drying of the sludge.

[0035] When the wet sludge is dried, a forklift forks out the drying hopper from the box-type sludge dryer 16, places the drying hopper on the unloading bracket, pries open the baffle plate 9, and presses down the unloading plate 11 by relying on the dead weight of the dried sludge. The unloading plate 11 pushes the limit stopper 13 away, and the unloading plate 11 rotates downward around the hinge 12 to open. At this time, the dried sludge falls out of the unloading port, and the dry sludge unloading is completed.

[0036] After unloading is completed, the unloading plate 11 is pushed upward so that the unloading plate 11 seals the discharge port 10, and the handle 8 is turned to drive the rotating unloading rod 7 to rotate, so that the limit stopper 13 contacts the unloading plate 11, and the limit stopper 13 supports the unloading plate 11, and then the baffle 9 is rotated so that the baffle 9 blocks the rotation of the handle 8, so that the limit stopper 13 can be fixed, and then the next batch of wet sludge is loaded into the drying hopper to complete the wet sludge loading and drying cycle.

[0037] Although the above describes the specific implementation methods of the present application in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present application. Technical personnel in the relevant field should understand that on the basis of the technical solution of the present application, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the present application.
