Description of the embodiments
In order that the utility model may become more readily apparent, a discharge device for a ball mill according to the utility model will be further described with reference to the accompanying drawings, wherein the specific embodiments described herein are for purposes of illustration only and are not intended to be limiting.
As shown in fig. 1 to 4, a discharge device of a ball mill comprises a seat ring 1 and a plug cover 2. The seat ring 1 is in a circular plate shape, the center of the seat ring is provided with a vertically through matching hole 11, the matching hole 11 is of a combined structure, and the seat ring comprises an inverted conical hole 111 and a straight hole 112, wherein the inverted conical hole 111 and the straight hole 112 are sequentially arranged from top to bottom and are connected with each other in the same diameter. The plug cover 2 comprises a plug head 21 and a gland 22 fixedly connected with the bottom end surface of the plug head 21, wherein the plug head 21 and the gland 22 are detachably connected through fasteners in view of processing, assembly manufacturability and maintenance convenience. The plug 21 is provided with a reverse taper platform 211 and a straight column 212 which are matched with the hole pattern of the matching hole 11, and the reverse taper platform 211 and the straight column 212 are of an integrated structure. The axial length (height) of the straight column 212 is longer than the axial length (height) of the straight hole 112, and the circumferential surface of the straight column 212 and the wall of the straight hole 112 are in slidable sealing fit all the time. When the plug cover 2 moves relative to the seat ring 1, a gap 23 exists between the matching surfaces of the back taper table 211 and the back taper hole 111 to form an opening structure; when the plug head 21 moves downwards, the matching surfaces of the back taper table 211 and the back taper hole 111 are tightly adhered to each other to form a sealed closed structure.
Here, the plug 21 may be made of a material having a certain strength and rigidity, and the circumferential surface thereof is capable of forming a sealing fit with the fitting hole 11, and in this embodiment, the plug 21 is made of a hard inner core 21a and a polyurethane layer 21b covering the surface thereof, the hard inner core 21a may be made of a metal material or a non-metal material of a polymer, such as steel, nylon, or a steel member covered with nylon, and the polyurethane layer 21b may form a sealing fit with the fitting hole 11. In addition, the hole wall of the matching hole 11 is covered with a lining protection layer 11a, and the protection layer 11a is a film layer formed by hard polyurethane materials so as to play roles of wear resistance and sealing. Of course, the sealing structure of the plug head 21 and the matching hole 11 can be realized by other conventional sealing modes such as a sealing ring.
A blind hole 24 is provided in the lower end face of the plug cover 2, and the blind hole 24 is provided along the axis of the plug head 21 and extends into the plug head 21. A group of filter holes 25 communicating with the blind holes 24 is provided on the peripheral surface of the plug 21, and the group of filter holes 25 is preferably provided on the back taper stage 211 and distributed uniformly in groups along both radial and axial directions of the back taper stage 211 to increase the filter flow area. When a gap 23 is formed between the back taper 211 and the back taper hole 111, the material flows into the blind hole 24 through the filtering hole 25 through the gap 23 and is discharged. It should be emphasized that the size of the gap 23 and the blind hole 24 formed therein are smaller than the smallest ball size of the ball mill, to prevent the balls from getting stuck in the gap and making the device impossible to close.
In some embodiments, in order to prevent the ground material from scattering during discharging, a discharging pipe 26 communicated with the blind hole 24 is fixedly connected to the plug cover 2, and the discharging pipe 26 is vertically arranged and is used for discharging the material in a concentrated manner under the guide flow of the discharging pipe, so that the contact with external pollution is reduced. In addition, a stop valve 27 is arranged on the discharge pipe 26 to control the on-off of the discharge pipe 26, so that the operation and control of an operator are facilitated.
Regarding the technical effect of achieving the up-and-down movement of the plug cover 2 relative to the seat ring 1, the following structure may be adopted: the gland 22 is provided with a group of threaded through holes 222 uniformly distributed on the circumference, the threaded through holes 222 are internally connected with jackscrews 3 in a threaded manner, the rod ends of the jackscrews 3 can be in contact and press fit with the lower end face of the seat ring 1, and the jackscrews 3 are full-thread bolts. The gland 22 is provided with a group of mounting light holes 221 uniformly distributed on the circumference, and screws 4 penetrate into the mounting light holes 221 and are in threaded connection with the seat ring 1; by adjusting the extension distance of the jackscrew 3 relative to the gland 22, the jackscrew 3 is pressed against the seat ring 1 and matched with the locking function of the screw 4, so that the position of the plug cover 2 relative to the seat ring 1 is adjustable up and down and can form fixed connection with the plug cover, and the purpose of moving and locking the plug cover 2 relative to the seat ring 1 up and down is realized.
As shown in fig. 5, the device can be detachably connected to the feed inlet 101 of the ball mill 100 through a fastener, specifically: the seat ring 1 is also provided with a group of circumferentially uniformly distributed mounting holes 12, bolts penetrate into the mounting holes 12 and are fixedly connected with the plane end of the feed inlet 101, and meanwhile, a sealing gasket 5 is also arranged between the pressing surfaces of the seat ring 1 and the feed inlet 101 so as to form detachable sealing connection between the seat ring 1 and the feed inlet 101. By adopting the method, a separately arranged discharge port can be eliminated, and the normal feeding mode is not influenced. In this structure, the gasket 5 and the seat ring 1 or the planar end of the feed inlet 101 are preferably stuck into an integral structure, so that the gasket 5 is prevented from falling off when the device is detached from the feed inlet 101. In addition, in order to facilitate the installation and positioning of the seat ring 1 and the feed inlet 101, the upper part of the seat ring 1 is provided with a spigot 13 with a flange, the horizontal end surface of the spigot 13 is a pressing surface matched with the plane end of the feed inlet 101, and the vertical peripheral surface of the spigot 13 is in clearance fit with the wall of the feed inlet hole of the feed inlet 101.
The working process of the device comprises the following steps:
when the ball mill 100 is used for feeding, the feeding port 101 is stopped at the upper top of the charging barrel 102, the feeding port 101 is opened for feeding by disassembling the device, and the device is hermetically arranged on the feeding port 101 after feeding is completed.
When the ball mill 100 discharges materials after finishing the grinding, the feeding port 101 stops at the lower bottom of the charging barrel 102. Firstly, the jackscrew 3 and the screw 4 are adjusted to enable the plug cover 2 to relatively move upwards, so that a gap 23 is formed between the plug head 21 and the matching hole 11, as shown in fig. 4; then the stop valve 27 is opened to discharge, after the discharge is finished, the plug cover 2 is moved downwards relatively by adjusting the jackscrew 3 and the screw 4, so that the gap 23 is closed and disappears, and meanwhile, the plug head 21 and the matching hole 11 are closed, as shown in fig. 5; finally, the shut-off valve 27 is closed again.
In the discharging process, the seat ring 1 and the plug cover 2 can realize material discharging only through forming the gap 23, compared with the prior art, the plug cover 2 is not required to be completely separated and detached, and therefore, the structure can avoid scattering of materials and contact with pollution sources such as a detaching tool, and meanwhile, the whole operation is convenient.
The above examples of the present utility model are merely illustrative of the present utility model and are not intended to limit the embodiments of the present utility model. Other variations or modifications of the above teachings will be apparent to those of ordinary skill in the art. It is not necessary here nor is it exhaustive of all embodiments.
