Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection, in particular to sludge processing equipment. Background Art

[0002] The plant utilizes a two-stage thermal drying process, consisting of thin-layer drying and belt drying. A sludge shredder is located between the two drying stages. Its function is to cut the lumpy sludge output from the thin-layer dryer into smaller strips and segments, thereby improving the drying efficiency of the subsequent belt dryer. The sludge shredder's discharge is concentrated, requiring a swinging distributor to distribute the shredded sludge to the belt dryer's feed end. This is a commonly used distribution device, equipped with a support shaft at the feed end and vertical sliding / rolling supports downstream of the swinging distributor's feed end. The swinging distributor continuously swings under the push and pull of a reciprocating mechanism.

[0003] However, the fabric conveyor belt of existing swing fabric machines is horizontally arranged; accordingly, the other auxiliary mechanisms of the swing fabric machine (such as the vertical sliding / rolling supports) are also arranged for a horizontal fabric conveyor belt. However, in some special occasions / scenarios, due to the existing terrain or the installation location of the equipment, the swing fabric machine needs to be tilted. In this case, the other auxiliary mechanisms of the swing fabric machine also tilt, and can no longer properly adapt to the tilted fabric conveyor belt. For example, the vertical sliding / rolling supports cannot provide stable support for the tilted fabric conveyor belt. During use, the support shaft is prone to breakage due to excessive load, and the swing fabric machine may tip over.

[0004] In addition, during the fabric conveying process of the swing fabric machine, sludge may adhere to the fabric conveyor belt and fall into other areas. Utility Model Content

[0005] In order to solve the technical problem that the vertical sliding / rolling support cannot provide stable support for the inclined fabric conveyor belt when the swing fabric conveyor is arranged tilted, the utility model provides a device that can provide stable support for the fabric conveyor belt in both vertical and horizontal directions. The main technical solutions adopted are as follows:

[0006] A sludge swinging distributor comprises a base and an end support shaft provided on the base, a reciprocating mechanism and a conveyor belt assembly. The end support shaft is arranged vertically, the lower end of the end support shaft is connected to the base, the inlet end of the conveyor belt assembly is connected to the upper end of the end support shaft, and the reciprocating mechanism is connected to the conveyor belt assembly and drives its discharge end to swing back and forth. The key points are:

[0007] The conveyor belt assembly is tilted, the feed end of the conveyor belt assembly is tilted upward, the discharge end of the conveyor belt assembly is tilted downward, and the bottom of the conveyor belt assembly is connected to a vertical support roller and a horizontal support roller;

[0008] A vertical restraining plate is provided on the base, and the vertical restraining plate is located on the discharge side of the horizontal support roller;

[0009] The vertical support roller contacts the base and rolls along it, and the horizontal support roller contacts the vertical restraining plate and rolls along it.

[0010] By setting up vertical support rollers and horizontal support rollers, the inclined conveyor belt assembly can be supported in both vertical and horizontal directions, thereby avoiding large radial loads on the end support shaft, ensuring the stable operation of the conveyor belt assembly and ensuring the stability of production. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 2 It is a structural schematic diagram of the discharge end of the conveyor belt assembly 3. DETAILED DESCRIPTION

[0013] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0014] like Figure 1 and Figure 2 As shown, a sludge swing spreading machine includes a base and an end support shaft 1, a reciprocating mechanism 2 and a conveyor belt assembly 3 arranged on the base. The end support shaft 1 is vertically arranged, and the lower end of the end support shaft 1 is installed on the base through a bearing mechanism. A ball head seat 7 is connected below the feeding end of the conveyor belt assembly 3, and the first end of the ball head seat 7 is connected to the conveyor belt assembly 3, and the second end of the ball head seat 7 is provided with a sleeve; the structure of the ball head seat 7 is the existing technology, and its first end and second end are connected by mutually cooperating ball heads and joint cavities, the upper end of the end support shaft 1 is inserted in the sleeve, and the end support shaft 1 and the sleeve are spline-matched.

[0015] The reciprocating mechanism 2 is connected to the conveyor belt assembly 3 and drives its discharge end to swing back and forth.

[0016] Specifically, the conveyor belt assembly 3 is tilted, the feed end of the conveyor belt assembly 3 is tilted upward, the discharge end of the conveyor belt assembly 3 is tilted downward, and the lower part of the conveyor belt assembly 3 is connected to a vertical support roller 4 and a horizontal support roller 5;

[0017] A vertical restraining plate 6 is provided on the base, and the vertical restraining plate 6 is located on the discharge side of the horizontal support roller 5;

[0018] The vertical support roller 4 contacts the base and rolls along it, and the horizontal support roller 5 contacts the vertical restraining plate 6 and rolls along it.

[0019] The vertical restraining plate 6 is an arc-shaped plate, the inner concave surface of the vertical restraining plate 6 faces the horizontal support roller 5, and the inner concave surface of the vertical restraining plate 6 is set with the center line of the end support shaft 1 as the center of the circle.

[0020] The conveyor belt assembly 3 swings back and forth with the end support shaft 1 as the center. Since the conveyor belt assembly 3 is tilted, the conveyor belt assembly 3 has a tendency to tilt / move toward its discharge end. If traditional vertical support is used, the tilt / movement direction of the conveyor belt assembly 3 cannot be supported. The end support shaft 1 is subjected to a large radial load for a long time, and there is a risk of breakage.

[0021] By providing the horizontal support rollers 5 and the vertical restraining plates 6 that cooperate with each other, the tilting / moving direction of the conveyor belt assembly 3 can be effectively supported.

[0022] In order to prevent the sludge adhered to the conveyor belt assembly 3 from falling to other areas, the conveyor belt assembly 3 includes two side plates 31 and a bottom guard plate 32 arranged vertically opposite each other. The two side plates 31 and the bottom guard plate 32 are connected to form a material distribution machine chute. The notch of the material distribution machine chute faces upward, and the material distribution machine chute is arranged along the feeding and discharging directions; the function of the bottom guard plate 32 is to guide the sludge falling thereon to the discharging end of the conveyor belt assembly 3.

[0023] Two belt rollers 33 are also provided between the two side plates 31. Both ends of the belt rollers 33 are mounted on the side plates 31 through bearings. One end of the belt roller 33 located at the feed end is connected to a conveying motor assembly. The same conveying belt 34 is wound around the two belt rollers 33.

[0024] A strip-shaped scraper 35 is also provided between the two side plates 31. The scraper 35 is located at the discharge end of the conveyor belt assembly 3. The scraper 35 is located below the rotating surface of the conveyor belt 34. One side of the scraper 35 is in contact with the outer surface of the conveyor belt 34.

[0025] The ends of the scraper blade 35 are hinged to the side plates 31. Torsion springs are positioned between the ends of the scraper blade 35 and the side plates 31, urging the scraper blade 35 to contact the outer surface of the conveyor belt 34. The scraper blade 35 scrapes away sludge adhering to the outer surface of the conveyor belt 34, while the bottom guard plate 32 protects the end support shaft 1 and reciprocating mechanism 2 below it from dust.

[0026] The reciprocating mechanism 2 includes a reduction motor, an eccentric wheel, a connecting rod and a rocker arm. The reduction motor is installed on the base. The eccentric wheel is fixedly mounted on the output shaft of the reduction motor. The eccentric position of the eccentric wheel is connected to one end of the connecting rod. The other end of the connecting rod is connected to the rocker arm. The rocker arm is fixed on the conveyor belt assembly 3.

[0027] Beneficial effects: The technical solution of the utility model is adopted, by arranging vertical support rollers and horizontal support rollers; it can support the inclined conveyor belt assembly in both vertical and horizontal directions, thereby providing stable support for the conveyor belt assembly, while avoiding the end support shaft from generating a large radial load and breaking, and preventing sludge from adhering to the conveyor belt assembly, thereby ensuring stable operation of the conveyor belt assembly and ensuring stable production.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present invention. Under the guidance of the present invention, ordinary technicians in this field can make various similar expressions without violating the purpose and claims of the present invention. Such changes fall within the scope of protection of the present invention.
