Abstract
The utility model discloses an extrusion cleaning type belt conveyor, relates to a belt conveyor for a coal washing plant belonging to the technical field of a conveyor, and is used for solving the defects of poor cleaning strength, large belt wear and short service life of a belt of a scraper cleaning type belt conveyor. The utility model adopts the proposals that the belt which surrounds a driving drum and a driven drum and a cleaning device are included. The cleaning device after being improved is in a rolling shaft extrusion type, and is formed by an upper nip drum and a lower nip drum which are arranged at intervals around the upper part and the lower part of a belt surface along the belt. The lower nip drum is corresponding to an interval retainer of the upper nip drum, the rolling surface of the lower nip drum is higher than the rolling surface of the upper nip drum, and both ends of the upper nip drum and the lower nip drum are provided with nip drum bearing seats. The upper nip drum and the lower nip drum are in friction with the belt in a rolling way, thereby the extrusion strength can be conveniently enhanced through changing the outside diameter, the interval retainer, the surmount of the lower nip drum, and the like, the problems of water and coal accumulation of a corridor of the belt are eliminated, the cleaning efficiency and the recovery rate of coals are enhanced, and the service life of the belt can be dramatically prolonged. The upper nip drum, the lower nip drum and the belt can be conveniently arranged at the optimum position below the belt around the belt surface through the bearing seats, and the extrusion cleaning type belt conveyor is suitable to being taken as the belt conveyor for the coal washing plant to use.
Description
Technical field
The utility model relates to the clearing apparatus of washery band conveyor, especially belt feeder, belongs to the band conveyor technical field.
Background technology
In the coal washing production process, the result of use of swabbing pig has determined the quality standardization degree of washery to a great extent in the band conveyor, and effective swabbing pig can significantly reduce Belt Passage ponding, optimize environment in the washery.At present, the clearing apparatus of washery band conveyor is single scraper-type swabbing pig, and this kind clearing apparatus can only strike off the ponding on the belt surface, the cleaning dynamics is poor, be difficult to obtain satisfied cleaning effect, cause the long-pending coal of long-term ponding in many Belt Passage, influence is produced; The cleaning process middle scraper all the time with the belt wipe contact, the belt serious wear, service life is short, frequently changing belt has increased the Maintenance and Repair work capacity again, and causes material consumption height, coal washing cost height.To sum up, need the cleaning mode and the device of existing band conveyor are improved.
Summary of the invention
The purpose of this utility model provides a kind of extruding cleaning formula belt feeder, to restrain the use defective of the existing scraper plate cleaning of existing clothes formula belt feeder.
The alleged problem of the utility model realizes with following technical scheme:
A kind of extruding cleaning formula belt feeder, belt and clearing apparatus around master, passive cylinder are arranged in the formation, its improvement is, described clearing apparatus is a roller bearing squash type clearing apparatus, by constituting along the last nip drum, the lower press rolls that are intervally arranged around the zone face upper and lower under the belt, barrier, the face that rolls all are higher than the face that rolls of nip drum between the corresponding one by one upward nip drum of lower press rolls, and the two ends of each upper and lower nip drum have the nip drum bearing seat respectively.
Above-mentioned extruding cleaning formula belt feeder, the back lower place of described drive roll is provided with the tensioner cylinder, and described upper and lower nip drum is along arranging around the zone face upper and lower near the following of tensioner cylinder.
The relative scraper-type cleaning of the utility model belt feeder has following characteristics:
1. the friction between upper and lower nip drum and the belt is a friction of rolling, surmount of the external diameter that can roll by conversion, a baffle, lower press rolls etc. improves the extruding dynamics easily, the problem of the long-pending coal of Belt Passage ponding be can effectively eliminate, sweeping efficiency and coal yield significantly improved;
2. do not have between scraper plate and belt the frictionally damage problem that cause of strong moving contact, reduced the wearing and tearing of belt greatly belt, significant prolongation the service life of belt;
3. upper and lower nip drum self structure is simple, easy to process, can be placed under the belt most favorable position place around zone face easily by bearing seat;
The suitable band conveyor as the washery of the utility model uses.
Description of drawings
Fig. 1 is the utility model structural representation.
The parts label is respectively in the accompanying drawing: 1-drive roll, the passive cylinder of 2-, 3-belt, the last nip drum of 4-, 5-lower press rolls, 6-nip drum bearing seat, 7-tensioner cylinder, 8-drum shaft bearing.
The specific embodiment
Consult Fig. 1.The utility model relates generally to the improvement of cleaning mode and swabbing pig, so the belt feeder in the illustrated embodiment is the basic structure scheme drawing with main, passive cylinder 1,2 and belt 3.Last nip drum 4 in the roller bearing squash type clearing apparatus that provides in the utility model, lower press rolls 5 are intervally arranged along following top around zone face, the below of belt 3, barrier between between the corresponding one by one last nip drum 4 of lower press rolls 5, the face that rolls of each lower press rolls 5 all is higher than the face that rolls of nip drum 4, and following belt passing round is wavy under the squeezing action of upper and lower nip drum.The two ends of each upper and lower nip drum have nip drum bearing seat 6 respectively, settle the suitable location that is fixed on down around the zone face upper and lower by nip drum bearing seat 6, the surmount of external diameter that can be by the upper and lower nip drum of conversion, interval span, quantity, lower press rolls etc. is obtained desirable extruding dynamics.In the illustrated embodiment, upper and lower nip drum is respectively that 2, external diameter are 50mm, span is 200mm at interval.
Still consult Fig. 1.In the utility model, drive roll 1 back lower place is provided with and prevents the belt 3 sagging tensioner cylinders 7 that skid, and at this moment, upper and lower nip drum 4,5 should be arranged along the following upper and lower around zone face near tensioner cylinder 7.
Claims (2)
1. one kind is pushed cleaning formula belt feeder, belt [3] and clearing apparatus around master, passive cylinder [1], [2] are arranged in the formation, it is characterized in that, described clearing apparatus is a roller bearing squash type clearing apparatus, by constituting along the last nip drum [4] that is intervally arranged around the zone face upper and lower under the belt [3], lower press rolls [5], barrier, the face that rolls all are higher than the face that rolls of nip drum [4] between the corresponding one by one upward nip drum [4] of lower press rolls [5], and the two ends of each upper and lower nip drum have nip drum bearing seat [6] respectively.
