Description

The utility model relates to hoisting-and-transport machinery, namely to elevator conveyors (norias), intended for the vertical transportation of grain and other bulk materials and can be used in elevators, mills, feed mills and grain plants, in beer industry, chemical industry and others .

Known noriya protected by A.S. USSR No. 1053779, cl. A 01 F 12/46, B 65 G 17/32, publ. 1983.11.15.

In the well-known elevator, each load-bearing element is made in the form of a separate spiral having the shape of a truncated cone or pyramid.

The disadvantage of noriya is the complexity of its manufacture.

Known noriya for seed, protected by A.S. USSR No. 1271408, class A 01 F 12/46, B 65 G 15/42, publ. 1986.11.23.

Noria contains a head with a drive station, connected by elevator pipes with a shoe and a loose toe, united by a frame, an endless ribbon placed in elevator pipes with buckets mounted on it, the front wall of which is made of elastic material.

In the well-known elevator, the possibility of traumatizing grain seeds remains. The disadvantage is the fire hazard design of the elevator.

Closest to the claimed technical essence and the achieved result, selected as a prototype, is the elevator for bulk materials, described in the book by V.N. Kulikov, M.E. Milovidov, Equipment for the enterprises of the elevator and grain processing industry, M., VO Agropromizdat, 1991, pp. 12-30.

The well-known elevator contains a head with a driving drum and a drive station, connected by welded elevator pipes with a shoe with a driven drum, an endless belt with bucket mounted on it, an explosive discharge device, an aspiration pipe, and control sensors. Drums are made cast of cast iron, and buckets are welded from sheet steel.

The disadvantages of the known elevator are high metal consumption, fire hazard due to slipping of an endless belt on a smooth drum, insufficient reliability due to increased load on the belt, and grain damage.

The problem solved by the proposed solution is the improvement of the elevator for bulk materials.

The technical result from the use of the utility model is to reduce the metal consumption, fire hazard, energy costs and dynamic loads, reduce the trauma of the grain, increase the reliability of the structure.

This result is achieved by the fact that the noria for bulk materials, containing a head with a driving drum and a drive station installed in it, connected by a noriya pipe with a shoe with receiving socks and a driven drum located in it, an endless tape placed in a noriya pipe with buckets mounted on it, the blasting device, suction pipe, control sensors, while the elevator pipes are made of prefabricated from the same parts on detachable joints, and the cylindrical surface of the master and slave drums made of individual plates. Bucket elevators are made of polymer material.

Figure 1 shows a front elevator view, figure 2 is a side elevator view, figure 3 is a shoe, figure 4 is a shoe, in section, figure 5 is a drum, figure 6 is a drum, cutaway.

The noria for bulk material contains a head 1 with a drive station 2 connected by elevator pipes 3, 4 with a shoe 5 with receiving socks 6, an endless belt 7 with buckets 8 mounted on it. A drive drum 9 is installed in the head 1, and a driven drum in the shoe 5 drum 10. A speed monitoring device 11 with sensors 12 is mounted on a noriya. On a noriya pipe 4 there is a sensor 13 for back-up and run-off of tape 7. In shoe 5 there is a tension device 14 equipped with vertical guides (not shown in FIG.). The drive station 2 contains a brake device 15 and an elastic clutch 16. From the precipitation, the drive station 2 is protected by a fence 17.

The head 1 is made detachable, equipped with a fuse 18 and is protected by a polyurethane insert (not shown in Fig.). The bearings of the driving drum 9 are mounted in housings rigidly on the walls of the head 1, in which the windows 19 are made for regulating the flow of the product during unloading.

Holes 20 are made in the elevator shoe 5 for monitoring the state of the endless belt 7, for cleaning grain, and gaps.

The elevator pipe 4 is equipped with an aspiration pipe 21 and the viewing window 22. The elevator pipe is equipped with an emergency shutdown post 23. The elevator pipes are joined by the corners 24 and the bracket 25. An unloading pipe 26 is installed on the head 1 of the elevator.

The work of the elevator is as follows.

Grain or other bulk material enters the elevator shoe 5 through the receiving socks 6. The drive station 2 rotates the drive drum 9 through the elastic coupling 16 and drives the endless belt 7 with buckets mounted on it 8. Passing around the driven drum 10 of the shoe 5, the buckets 8 are loaded and rise to the head 1 of the elevator, where under the action of centrifugal force unload in the discharge pipe 26. Elevator pipes 3, 4 provide structural rigidity and the vertical direction of movement of the endless tape 7.

The device 11 for speed control with sensors 12 and sensor 13 runaway tape provide control of the elevator. The tension device 14 adjusts the tension of the endless belt 7. The brake device 15 brakes the endless belt 7 from slipping in the opposite direction and stops the belt. The fuse 18 protects the design of the elevator from mechanical destruction during the explosion. Through the windows 19 provides access to adjust the flow of grain or bulk material during unloading. The suction pipe 21 installed on the elevator pipe 4 provides for the aspiration of the internal elevator volume, and the inspection windows 22 provide visual control and access to the installation of the endless tape 7. Post 23 provides emergency disconnection of the elevator if necessary. The rigidity of the structure is provided by the corners 24 and the bracket 25.

The head housing 1 of the elevator is made of sheet steel and it can be painted with anti-corrosion paint. The drive shaft with the driving drum 9 mounted on it is mounted on rolling bearings and is mounted with bearing housings and brackets on the head housing 1.

The elevator shoe 5, made of steel sheet metal, consists of a housing, a driven shaft, with a drum 10 mounted on it. The shoe housing has flanges for connecting elevator pipes 3, 4, a flange for connecting a loading nozzle .. A driven shaft with a drum mounted on it 10 is mounted on rolling bearings. The drive station 2 consists of a gear motor, an elastic coupling 16, a guard 17 and an engine plate. For the convenience of mounting the tape, mounting and replacing buckets, elevator pipes with a longitudinal connector are used. The traction organ of the elevator is a belt (tape) in the form of an endless branch, covering the leading and driven drums. Buckets are attached to the tape with special

mounting bolts, nuts and washers. Capacitive sensor 13 for the escape of the tape, the sensors 12 are connected to the device 11 for speed control, for example, UZKS-01.2-1. A brake device 15 is mounted on the shaft of the driving drum 9. The elevator pipes 3, 4 are made of sheet stamped parts, for example, ducts, flanges, and are connected with bolts. The blasting device is made in the form of nozzles on the head of the noriya or on the noriya pipes equipped with a membrane and a lattice. As membranes, it is recommended to use polyethylene films of brands T, ST, SIK, SK, V or N GOST 10354-82. To protect the membranes from rupture under the action of rarefaction, a wire mesh 1-2 mm thick with 30 × 30 mm mesh should be installed inside the elevator. The drums 9, 10 are made of separate metal plates mounted on a common hub, providing good adhesion to the tape and self-cleaning the surface of the drum. The suction pipe is connected to the suction network of the enterprise. The tension device 14 is made in the form of a screw pair. The brake device 15 is a reverse clutch. The fence 17 is made of sheet steel. The emergency shutdown post 23 is an elevator circuit breaker.

Thus, in the proposed elevator in comparison with the prototype increases the level of fire safety due to the exclusion of slipping of an endless tape on a plate drum. Reducing the weight of the tape with buckets in the proposed elevator leads to a decrease in dynamic loads and, as a result, to a decrease in the trauma of grain, a reduction in energy costs and metal consumption. In addition, we increase the reliability of the clutch of drums with an endless belt and the convenience and cost reduction during the installation of elevators.
