RU2276623C1 - Grader cylinder - Google Patents

Abstract

FIELD: separating solids from solids.

SUBSTANCE: grade cylinder comprises chute with port and rim and screw mounted inside it, front and back sockets mounted on the front and back sides of the cylinder, respectively, receiver for inflowing and outflowing material mounted at the inlet of the front socket. The front socket is provided with the throat made of a pipe whose back side embraces the rim of the chute and is provided with blades that cooperate with the material outflowing from the chute. The blades are mounted between the outer side of the throat and the rim of the front socket and cooperate with the material inflowing to the cylinder from the receiver.

EFFECT: enhanced efficiency and reliability.

Description

The invention relates to machines for the separation of bulk materials, such as crops, in length.

Known Trier [RF Patent No. 2044577, IPC ⁶ V 07 In 13/02, publ. September 27, 1995], comprising a cylinder with cells and a tray with a screw installed inside the cylinder.

Known gauge cylinders, for example HSR 1010 from HEID, Austria, K-236 from PETKUS Germany, include a shaft with a spiral on which a receiver, tray, front and rear sockets are mounted. With this design of the triera, material from the tray and from the cylinder is discharged from one side opposite to the receiver, which structurally complicates the process of unloading the material directly in the tank.

Also known trireme cylinder [ZAV-10.90.000, "Grain-cleaning unit ZAV-40", Guide to the device and operation, Voronezh, ed. "Commune", 1980, p. 80], including a tray with a window and a rim and a screw installed inside it, front and rear sockets mounted respectively on the front and rear sides of the cylinder, and an input material receiver installed on the front socket input. The rear outlet and the tray auger are mounted on the cylinder shaft, and the front outlet is freely mounted on the support rollers. The material entering the cylinder from the receiver through the front outlet enters the cylinder on its working surface equipped with cells. With this design of the triera, material from the tray and from the cylinder is discharged from opposite sides, which reduces the number of conveyors needed and facilitates the process of unloading the material directly in the tank.

Tee cylinders, in which the front outlet is freely mounted on the support rollers, have low performance due to wear of the contact surfaces of the rollers, made, as a rule, of elastic materials with a high coefficient of friction. During rotation, the cylinder begins to vibrate, resulting in reduced separation efficiency. At the same time, low-flowing materials may be deposited in the tray in the area of its rim.

The aim of the invention is to remedy these disadvantages, increase the operability of the indent cylinder and separation efficiency, improve the conditions for introducing material into the cylinder and withdrawing material from the cylinder.

This goal is achieved by the fact that in the trimeric cylinder, which includes a tray with a window and a rim and a screw installed inside it, front and rear sockets mounted respectively on the front and rear sides of the cylinder, and an input material receiver installed on the front socket inlet, the front socket is supplemented a neck in the form of a pipe, the back of which covers the rim of the tray and is equipped with inside blades that interact with the material coming out of the tray, and between the outer side of the neck and the rim of the front socket of the mouth Blades have been installed that interact with the material from the receiver entering the cylinder, and the front part of the neck with overlapping is placed in the opening of the receiver wall.

The joints of the neck with the rim of the tray and with the wall of the receiver are equipped with seals.

For the convenience of setting up the indent cylinder for processing material with other properties, its working surface is collapsible.

To eliminate vibration and beating of the indent cylinder during operation, its working surface, tray auger, front and rear sockets, front neck with blades and blades are mounted coaxially.

Figure 1 shows a General view of the indent cylinder.

Figure 2 shows a section aa in figure 1.

Figure 3 shows the node B in figure 1.

The indented cylinder includes a tray 1 with a window 2 and a rim 3 installed inside the tray 1 auger 4, front 5 and rear 6 sockets, respectively installed on the front and rear sides of the cylinder, the receiver 7 of the input material installed on the input of the front socket 5. Front socket 5 supplemented by a neck 8 in the form of a pipe, the back of which covers the rim 3 of the tray 1 and is equipped with vanes 9 that interact with the material coming out of the window 2 of the tray 1, then entering the receiver 7, and between the outside of the neck 8 and the rim 10 of the front rose For example, blades 11 are installed, interacting with the material entering the cylinder from the receiver 7, with the front part of the neck 8 overlapping placed in the hole in the wall 12 of the receiver 7. The receiver 7 includes two non-communicating cavities - the top 13 and the bottom 14 - for incoming raw material and processed material from tray 1, respectively. The junction of the neck 8 with the rim 3 of the tray 1 and with the wall 12 of the receiver 7 is provided with seals 15, 16. The working surface of the indent cylinder is collapsible, including segments 17. The front 5 and rear 6 outlets are equipped with hubs 18 mounted coaxially with the screw 4 of cylinder tray 1 .

Trier cylinder works as follows.

The processed material from the upper cavity 13 of the receiver 7 enters the front of the outlet 5 on the outside of the rotating neck 8 and then the blades 11 are dumped onto the working surface of the segments 17 of the cylinder. The material placed in the cells rises and falls into the tray 1, and from it with the screw 4 through the window 2 and the rim 3 is sent inside the neck 8, from where, using the blades 9, it is discharged into the lower cavity 14 of the receiver 7. Seals 15 and 16 prevent the mixing of material fractions at the entrance to the cylinder and the exit from the tray 1. Material that does not fit into the cells, due to the backing of the material from the front of the outlet 5, comes off the cylinder from the side of the rear outlet 6.

Coaxial installation of the auger and hubs of the front and rear outlets allows you to eliminate vibration and runout of the indent cylinder during operation, to improve the smoothness and operability of the indent cylinder, and also the efficiency of material separation. Due to the rotation of the neck and the presence of blades and vanes, the conditions for introducing material into the cylinder and withdrawing material from the cylinder are improved, the occurrence of material is eliminated.
