Description

[Detailed description of the invention] [Industrial use! ! TECHNICAL FIELD The present invention relates to a continuous vibrating rod mill having a horizontal cylindrical crushing tube (vessel) that is vibrated circularly in a vertical plane.

[Prior Art] Conventionally, the above-mentioned vibrating rod mill has been developed, for example, by
As described in Publication No. 848, the crushing cylinder is formed by a cylindrical body and an end plate that closes both ends of the body, and an opening for immersion of the object to be crushed is provided at one end of the upper part of the n-body between the crushers, and A crushing product discharge port is provided at the other end of the lower body of the crushing cylinder.

In the above-mentioned four-component vibrating rod mill, the material to be pulverized inserted through the immersion port is pulverized by the circular vibration of the pulverizing tube, and the rods charged into the pulverizing volume collide with each other and the rods and the inner wall of the pulverizing tube. , which is discharged as a crushed product from the discharge port.

[Problems to be Solved by the Invention] However, in the conventional vibrating rod mill described above, when inspecting the wear condition of the rod or loading the rod, one end plate of the crushing tube must be removed from the body. Therefore, there is a problem that inspection work and charging work become complicated.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a vibratory rod mill in which inspection and loading of rods can be easily performed.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention provides a continuous vibrating mill having a horizontal cylindrical crushing chamber which is vibrated circularly in a vertical plane. A viewing window is provided at the top of at least one end plate, and this viewing window is closed by a removable lid.

[Function] According to the above means, the inspection work and the charging work of the wood charged into the crushing cylinder are performed through the viewing window with the lid removed.

[Example] Hereinafter, one embodiment of the present invention will be described based on the drawings.

Crushed products (not shown) are placed at both ends of the lower part of the fuselage 2.
A first discharge lower and a second discharge port 8 are provided for discharging the fuel. There is.

On the other hand, at the lower part of both end plates 3 of the crushing tube 1, there is a third discharge port 9 for discharging the crushed products in the same way as the first and second discharge lowers 8.
and a fourth discharge port 10 are provided, and these discharge ports 9 and 10 are appropriately larger than the first and second discharge lowers 8. A lid 11 or a discharge duct 12 is removably attached to i3 and the fourth discharge ports 9 and 10, which are provided when not in use or in use. A lid plate for closing the discharge hole and a perforated plate fitted to the discharge hole are provided so as to be suppressable. Furthermore, viewing windows 13 and 14 are provided at the upper portions of both end plates 3 of the crushing tube 1. They also serve as respective viewing holes, and are provided so as to be closable by removable lids 13a and 4a that close the viewing holes of the end liner, which will be described later.

A body liner 15 made of high manganese 8JJ steel with excellent wear resistance is attached to the inner circumferential surface of the crushing gap 2 in the crushing tube 1. The fuselage liner 15 has 4 lines in the circumferential direction.
It consists of four divided segments 15a in the moving direction, and each segment 15a has a bolt hole provided at each of the four corners, a bolt 16a inserted into a corresponding hole provided in the body 2, and a bolt 16a inserted into a corresponding hole provided in the body 2. Bolt 1 protruding from
It is removably attached to the inner peripheral surface of the body 2 at appropriate intervals in the circumferential direction by a plurality of fasteners 16 consisting of nuts 16b screwed to the ends of the fasteners 16, and the nuts 16b of the fasteners 16 and the body 2. There is a segment 1 between the outer peripheral surface of the
A disc spring 17 is interposed to prevent rattling due to stretching of 5a. And the first and second immersion ports 5.6 of the fuselage 2
and a toilet liner 15 corresponding to the first and second outlet ports 8
The segment 15a is provided with a recess hole 18.19 and an outlet 20.21.

Further, on the inner wall surface of the end plate 3 of the crushing tube 1, an end liner 22 made of high manganese 8rJt74, ceramics, etc. with excellent wear resistance is provided with bolt holes provided around the end liner and the end plate 3 corresponding to the bolt holes provided around the end liner 22. A plurality of fasteners 2 each consisting of a bolt 23a inserted into a hole provided in 3 and a nut (not shown) screwed onto the end of the bolt 23a protruding from the end plate 3.
3, it is removably attached to the inner wall surface of the end plate 3 with a cushioning material 24 interposed therebetween. Each end liner 22 corresponding to the third and fourth discharge ports 9.10 of each end plate 3 is provided with a discharge hole 25 that is a tapered hole that widens outward. Each outlet 25 has a third outlet 9, a fourth outlet 9.
A truncated conical cover plate 26 or perforated plate 27 is removably fitted depending on whether the IO is unused or used, and these cover plates 26 or perforated plates 27 can be used as ill or perforated plates as described above. The discharge duct] 2 is pressed with a cushion material 28 interposed therebetween. The perforated plate plate 27 has five rice varieties with different sizes of slits 27a, and is replaced as necessary. A viewing hole 29 is also provided in each end liner 22 corresponding to the viewing port 3.14 of each end plate 3.

In the figure, 30 is a cooling jacket provided on the outer periphery of the body 2, and an inlet 31 and an outlet 32 for cooling water etc. are provided at the lower and upper parts of the cooling jacket 30.

i! of the above configuration! 1! In the continuous type vibrating rod mill,
While each oscillator is operated synchronously to cause the crushing cylinder I to vibrate circularly in a vertical plane at a high acceleration of 100 degrees or more, the object to be crushed is immersed from an appropriate working force of 5.6. The material to be crushed is crushed by collisions between the rods inserted into the crushing cylinder 1, collisions between the rods and the fuselage liner 15, etc., and is passed through the perforated plate 27 or directly to the appropriate discharge lowers 8, 9. From No. 10, the crushed products fall and are discharged outside the machine.

Therefore, when inspecting the wear condition of the iron loaded into the crushing tube 1, it is necessary to
When removing and visually inspecting the rod, or when inserting the rod,
Similarly, the lid 13a.

14a is removed and inserted through the viewing windows 13 and 14.

In the above embodiment, the observation windows 13. of the both end plates 3 of the crushing cylinder 1 are +4 is set to the same height, but the height is not limited to this, and the height may be changed depending on the change in the filling rate of the rods.

Further, the viewing windows 13 and 14 are not limited to being provided on both end plates 3, but may be provided only on one end plate 3.

[Effects of the Invention] As described above, according to the present invention, the inspection work and charging work of the rond are performed through the viewing window, so there is no need to remove the end plate from the body as in the conventional case, and the rond in the crushing cylinder is This makes it extremely easy to perform inspection work and insert rods into the crushing cylinder.
