Description

Technical Field

[0001] This utility model relates to the field of sludge treatment technology, specifically to a storage mechanism for a sludge drying and incineration treatment system. Background Technology

[0002] The storage structure of the sludge drying and incineration treatment system can receive wet sludge or dried sludge transported from the sewage treatment plant, providing a buffer for subsequent treatment stages. The dry sludge silo can store sludge dried by the dryer for unified subsequent incineration and other treatments.

[0003] The existing utility model patent with publication number CN212314500U discloses a municipal sludge drying granule storage silo, including a support frame and a main silo body installed on top of the support frame. The bottom end of the main silo body has an arc surface, and a material conveying shell is installed on one side of the arc surface at the bottom end of the main silo body. A power mechanism is installed on the arc surface. At least one assembly silo body is installed on the top end of the main silo body through an assembly mechanism. The assembly mechanism includes a connecting flange and a slot. The slot is integrally installed on the bottom end of the assembly silo body, and the top end of the main silo body extends into the slot. The upper and lower parts of the connecting flange are respectively installed on the bottom end of the slot and the edge of the top surface of the main silo body. This utility model, through a series of structures, enables the municipal sludge drying granule storage silo to achieve the assembly and use of multiple silos, facilitating the storage of different quantities of dried granules, achieving a sufficient sealing effect, and providing moisture-proof function, which is beneficial for practical use.

[0004] The humid air inside the aforementioned silo may condense and release moisture, causing the dried sludge to absorb water and clump together, increasing the pushing force during discharge and, in severe cases, affecting normal discharge. In summer, if the silo is located outdoors and exposed to direct sunlight, the internal temperature rises, potentially causing the dried granules to ferment and produce toxic, harmful, and flammable gases, increasing safety risks and affecting the quality of the dried granules. Although the silo is designed with curved surfaces and spiral blades to assist discharge, the dried granules may still be squeezed and jammed at the discharge port due to their large surface roughness and irregular shape. Especially when the storage volume is large, after prolonged discharge, the spiral blades may not be able to smoothly push all the granules to the conveying shell, still posing a risk of discharge port blockage and affecting discharge efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a storage mechanism for a sludge drying and incineration system, which solves the problems of outlet blockage and the generation of toxic gases due to internal fermentation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A storage mechanism for a sludge drying and incineration treatment system includes a support frame, and a storage mechanism is disposed above the support frame.

A feeding auger is fixedly installed at the bottom end of the drive shaft, and a feeding motor is connected to the top end of the drive shaft.

[0010] Preferably, the silicone plates are vertically and equidistantly installed inside the storage tank with the center of the tank as the reference, the top cover is fixedly connected to the storage tank by bolts, the air inlet of the air pump passes through the top cover and communicates with the inner cavity of the storage tank, and the receiving hopper has a conical structure.

[0011] Preferably, the surface of the receiving hopper is provided with an "X"-shaped perforation structure that is fitted into the metal mesh. The metal mesh is fixedly installed in the perforation structure of the receiving hopper. The baffle and the limiting frame are slidably connected.

[0014] Beneficial effects

[0015] This invention provides a storage mechanism for a sludge drying and incineration treatment system. Compared with the prior art, it has the following advantages:

[0016] (1) The storage mechanism of this sludge drying and incineration treatment system continuously draws air from the inside of the storage tank through an air pump, creating a negative pressure inside the tank. External air can enter the storage tank through the auger conveyor's pipeline structure, forming a circulating airflow to promptly discharge any potentially toxic or harmful gases and reduce gas accumulation. At the same time, the silica gel plates inside the tank store the sludge in layers, reducing the sludge's bulk density and minimizing the localized enclosed environment caused by dense sludge accumulation. Combined with airflow circulation, this disrupts the sealed, oxygen-deficient conditions required for fermentation, thereby inhibiting the generation of toxic gases.

[0017] (2) The storage mechanism of this sludge drying and incineration system uses a feeding auger to rotate and push sludge within the receiving hopper. The top of the feeding auger is located within the conical structure of the receiving hopper, and the bottom extends into the cylindrical structure of the receiving hopper, allowing it to directly act on the sludge in the discharge path and preventing sludge from being squeezed and stuck at the discharge port. The conical structure of the receiving hopper guides the sludge to naturally gather towards the center, which, combined with the rotating pushing of the feeding auger, enhances the smoothness of the discharge. In addition, the silica gel plate inside the storage tank deforms under the gravity of the sludge above, causing the sludge above to continuously collapse and fall, preventing sludge caking and ensuring a continuous supply of material to the receiving hopper. The electric actuator controls the sliding opening and closing of the baffle to adjust the discharge speed, matching the pushing capacity of the feeding auger, and preventing sludge from clogging at the outlet due to excessive discharge speed.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 This utility model provides a technical solution: a storage mechanism of a sludge drying and incineration treatment system includes a support frame 1, and a storage mechanism 2 is arranged above the support frame 1.

[0025] Storage assembly 21 includes a storage tank 211 fixedly installed inside a support frame 1. A silicone plate 212 is fixedly installed inside the storage tank 211. A top cover 213 is fixedly installed at the top of the storage tank 211. An air pump 214 is fixedly installed above the top cover 213. A receiving hopper 215 is fixedly installed at the bottom of the storage tank 211. A metal mesh 216 is fixedly installed on the surface of the receiving hopper 215. A limit frame 217 is fixedly installed at the bottom of the receiving hopper 215. Electric actuators 218 are fixedly installed on both sides of the limit frame 217. A baffle 219 is fixedly installed at the movable end of the electric actuator 218. The silicone plate 212 is positioned above the storage tank 211. The top cover 213 is fixedly connected to the storage tank 211 by bolts. The air inlet of the air pump 214 passes through the top cover 213 and communicates with the inner cavity of the storage tank 211. The receiving hopper 215 has a conical structure. The surface of the receiving hopper 215 is provided with an "X"-shaped perforation structure that fits into the metal mesh 216. The metal mesh 216 is fixedly installed in the perforation structure of the receiving hopper 215. The baffle 219 and the limiting frame 217 are slidably connected. The center of the limiting frame 217 is provided with an perforation structure that passes through the limiting frame 217 and fits into the bottom columnar structure of the receiving hopper 215.

[0026] Specifically, the storage tank 211 can store sludge. The silicone plate 212 inside the storage tank 211 is composed of a circular structure on the outside and multiple fan-shaped structures inside, which can provide a certain support for the sludge and make the sludge layered. After the sludge at the bottom is discharged, it will deform under the influence of the gravity of the sludge above, causing the sludge above to collapse as a whole to prevent the sludge from caking. The metal mesh 216 on the surface of the receiving bucket 215 has a mesh size of five millimeters, which can reserve a channel for liquid discharge and support the sludge. When the air pump 214 above the top cover 213 is started, it can continuously extract the air above the sludge layer, so that the air pressure above the sludge layer is reduced. The external air will pass through the pipe structure inside the auger conveyor 222, so that an airflow is formed above the sludge layer. When the electric push rod 218 is at the retraction limit, the baffle 219 will be inside the limit frame 217, sealing the bottom end of the tubular structure of the receiving bucket 215.

[0027] The conveying assembly 22 is installed inside the storage tank 211 for conveying dry sludge. The conveying assembly 22 includes a fixed frame 221 fixedly installed on the outside of the storage tank 211. An auger conveyor 222 is fixedly installed on one side of the fixed frame 221. The conveying assembly 22 also includes a drive shaft 223 movably installed at the center of the storage tank 211. A feeding auger 224 is fixedly installed at the bottom end of the drive shaft 223. A feeding motor 225 is connected to the top end of the drive shaft 223. The auger conveyor 222 is fixedly connected to the storage tank 211 through the fixed frame 221. The end of the auger conveyor 222 is connected to the inner cavity of the storage tank 211. The top end of the drive shaft 223 passes through the top cover 213 and is rotatably connected to the top cover 213. The top end of the feeding auger 224 is located inside the conical structure of the receiving hopper 215, and the bottom end is located inside the cylindrical structure at the bottom end of the receiving hopper 215. The feeding motor 225 is fixedly connected to the top cover 213.

[0028] Specifically, the auger conveyor 222 can transport sludge into the storage tank 211, and the drive shaft 223 can drive the feeding auger 224 to rotate under the drive of the feeding motor 225, so that the feeding auger 224 can discharge the sludge from the storage tank 211.

[0029] Specifically, the air pump 214 is model RB-61D-2, the electric actuator 218 is model AIME-50-100-1610, and the feeding motor 225 is model AM8032-0D20-0000. In addition, all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0030] During operation, the auger conveyor 222 is fixed to the outside of the storage tank 211 via the fixing frame 221, transporting the dried sludge to the inner cavity of the storage tank 211. Inside the storage tank 211, vertically equidistant silicone plates 212 provide layered support and storage for the sludge. The top cover 213 is bolted to the top of the storage tank 211, and the air pump 214 above it connects to the inner cavity of the storage tank 211 through the top cover 213, continuously drawing air out of the storage tank 211 to create an airflow. When discharge is required, the electric actuators 218 on both sides of the limit frame 217 are activated, and the movable end drives the baffle 219 to the limit position. The slid on the frame 217 opens the bottom outlet of the receiving hopper 215; at the same time, the feeding motor 225 on the top cover 213 starts, driving the drive shaft 223 through the top cover 213 to rotate, and the feeding auger 224 at the bottom of the drive shaft 223 rotates accordingly. The top of the feeding auger 224 is located inside the conical structure of the receiving hopper 215, and the bottom is located inside the cylindrical structure of the receiving hopper 215, so that the sludge in the storage tank 211 is transported to the outside through the receiving hopper 215. The metal mesh 216 distributed in an "X" shape on the surface of the receiving hopper 215 assists in supporting the sludge and allows airflow or liquid to pass through during the process.
