Abstract
The utility model discloses a kind of rotary drum knocking device, comprise guide cylinder, copper ball and electro-magnet, described guide cylinder is vertically arranged on the top of rotary drum, gap is had between the lower end of described guide cylinder and rotary drum, this gap is less than the external diameter of copper ball, described electro-magnet is arranged on the upper end of guide cylinder, and described copper ball is arranged in guide cylinder, and electro-magnet coordinates the top of knocking rotary drum with copper ball.The utility model effectively can shake the loose fertilizer be bonded on inner wall of rotary drum.
Description
Technical field
The utility model relates to whizzer field, particularly relates to a kind of rotary drum knocking device.
Background technology
Current, adopting drum granulating method to produce in the process of compound manure, often to pass into water vapor to increase the humidity of raw material, thus fertilizer can be bondd balling-up better.But moisture content too much in compound fertilizer product can affect the quality of product, therefore, in order to reduce in product, moisture content is to acceptability limit, and the general whizzer that adopts is dried compound manure.In drying course, because the compound manure moisture content just entered in whizzer is higher, easily stammer on the barrel of whizzer, had a strong impact on production efficiency and the quality of compound fertilizer product.Meanwhile, the heat waste of carrying to whizzer due to roasting kiln is comparatively large, and the waste of coal caused thus and electric power resource.
In order to solve the problems of the technologies described above, in prior art, propose following technology:
As China Patent No. " 201320120239.3 " discloses a kind of whizzer, its publication date is on October 16th, 2013, its technical scheme is described whizzer, comprise rotating cylinder, described rotating cylinder is provided with multiple automatic knocking device, and described automatic knocking device comprises striking mechanism, position-limit mechanism and reinforcing mechanisms; Wherein, described striking mechanism is hinged on the outer wall of described rotating cylinder by rotating shaft, the axis of described rotating shaft and the axis being parallel of described rotating cylinder; Described position-limit mechanism is fixed on the outer wall of described rotating cylinder, and the contrary side of the sense of rotation being positioned at described rotating cylinder is for limiting the turning direction of described striking mechanism; Described reinforcing mechanisms is fixed on the outer wall of rotating cylinder, and the side that the sense of rotation being positioned at described rotating cylinder is identical, the beating point of described striking mechanism on rotating cylinder is positioned on described reinforcing mechanisms.But the knocking device in this patent is arranged on rotating cylinder, causes the manufacturing procedure of rotating cylinder complicated, be not easy to safeguard.Meanwhile, the knock dynamics of this knocking device to rotating cylinder is more weak, is not easy loose for the shake of the fertilizer of stammerer.
Utility model content
The purpose of this utility model is to overcome the above-mentioned problems in the prior art, provides the rotary drum knocking device that a kind of structure is simple, easy to maintenance, and the utility model effectively can shake the loose fertilizer be bonded on inner wall of rotary drum.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of rotary drum knocking device, it is characterized in that: comprise guide cylinder, copper ball and electro-magnet, described guide cylinder is vertically arranged on the top of rotary drum, gap is had between the lower end of described guide cylinder and rotary drum, this gap is less than the external diameter of copper ball, described electro-magnet is arranged on the upper end of guide cylinder, and described copper ball is arranged in guide cylinder, and electro-magnet coordinates the top of knocking rotary drum with copper ball.
Described guide cylinder is formed by two and half fastenings.
Described knocking device also comprises support, and the top and bottom of described guide cylinder are bolted on support.
Employing the utility model has the advantage of:
One, in the utility model, can be spacing to copper ball by guide cylinder, make it can only be reciprocating in guide cylinder, the percussion power of copper ball to rotary drum can be increased, the shake of the fertilizer be bonded on rotary drum inwall is fallen apart better effects if.Adopt copper ball to have the advantage of the little and Heavy Weight of volume, the volume of guide cylinder can either be reduced, can concentrate again and knock, be conducive to increase and knock dynamics.Realize knocking to the adsorptive power of copper ball by electro-magnet, whole knocking device and rotary drum are split-type structural, have the advantage that structure is simple, with low cost and easy to maintenance.In addition, beating point of the present utility model is arranged on the top of rotary drum, and such structure can fast and effectively to be fallen apart the fertilizer be bonded on inner wall of rotary drum in earthquake.This is because the self gravitation being positioned at the fertilizer of rotary drum inwall vertex is maximum, and the reactive force of rotary drum to fertilizer is minimum, and thus the fertilizer of rotary drum vertex is easily the loosest by shake.
Two, in the utility model, described guide cylinder is formed by two and half fastenings, and this structure is conducive to the later maintenance of knocking device.
Three, in the utility model, described knocking device also comprises support, and the top and bottom of described guide cylinder are bolted on support, and this structure makes the stability of guide cylinder higher, can prevent because guide cylinder tilts and security incident occurs.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Being labeled as in figure: 1, guide cylinder, 2, copper ball, 3, electro-magnet, 4, rotary drum, 5, support.
Embodiment
A kind of rotary drum knocking device, comprise guide cylinder 1, copper ball 2 and electro-magnet 3, described guide cylinder 1 is vertically arranged on the top of rotary drum 4, have gap between the lower end of described guide cylinder 1 and rotary drum 4, this gap is less than the external diameter of copper ball 2, skids off from this gap for preventing copper ball 2, ensure that the accuracy of knocking is better, described electro-magnet 3 is arranged on the upper end of guide cylinder 1, and described copper ball 2 is arranged in guide cylinder 1, and electro-magnet 3 coordinates the top of knocking rotary drum 4 with copper ball 2.
In the utility model, described guide cylinder 1 is formed by two and half fastenings, and further, described knocking device also comprises support 5, and the top and bottom of described two and half are all bolted on support 5.
Enforcement principle of the present utility model is: whole knocking device is arranged on after above rotary drum 4, copper ball 2 under gravity with the upper contact of rotary drum 4, but by the restriction of guide cylinder 1, copper ball 2 is positioned at guide cylinder 1 all the time, electro-magnet 3 is energized, under the effect of magnetic force, copper ball 2 is adsorbed to guide cylinder 1 top, then to electro-magnet 3 power-off, copper ball 2 just knocks rotary drum 4 downwards from guide cylinder 1 top, copper ball 2 after knocking pops up under the effect of bounce, now be energized electro-magnet 3 again, copper ball 2 is attracted to again guide cylinder 1 top, so go round and begin again, realize knocking of rotary drum 4.
