Abstract
The automatic pulp surface controller for floatation machine is used in the liquid level control of pulp in the floatation process of metal, non-metal and chemical industry. Consists of a buoy system, a lever and an ore drawing valve body system. The device has reasonable structure and reliable performance, can realize automatic control of the flotation process on the pulp liquid level, maintain constant pulp liquid level and certain foam layer thickness, obtain reasonable concentrate grade and improve the metal yield.
Description
Flotation device ore pulp face self-con-tained unit relates to the control device of ore pulp face of the floatation process of metal, nonmetal and industrial chemicals, is used for the level control in the flotation device.
In floatation process, constant ore pulp face height promptly keeps certain froth bed thickness, is the assurance that obtains rational concentrate slurry grade and improve the metal yield.Because all multifactor influences such as ore-dressing technique, cause the ore pulp face to be difficult to keep stable, need a kind of effective ore pulp face control device.
At present, the way of constant ore pulp face height has two kinds, and the one, with the position of manual adjustment ore discharge overflow valve plate, with the height of constant ore pulp face.This method is that most of producers adopt because this method is subjected to manually-operated restriction, regulate untimely, judgment accuracy is poor, causes ore pulp face fluctuation very big.The 2nd, combination instrument control method is measured ore pulp face height automatically by instrument, feeds back to robot control system(RCS), by control ore discharge valves such as sensor, electronic differential pressure transmitters, reaches the purpose of constant ore pulp face.Whom becomes on this method and technology, but instrument price height, system's acquisition expenses is big, has limited its application and popularization.
The purpose of this utility model is exactly that it is simple in structure, and is economical and practical for a kind of flotation device ore pulp face self-con-tained unit is provided, and can control ore pulp face in the flotation device effectively, obtains rational concentrate grade and improves the metal yield.
The utility model is achieved through the following technical solutions.
Flotation device ore pulp face self-con-tained unit is characterized in that:
A. flotation device ore pulp face self-con-tained unit reaches and the lever of lever pillar by hinge-coupled by be fixed on the lever pillar that is fixed on the support of the flotation device cell body outside by ore drawing oral-lateral top with support, unify by the joining valve system composition of hinge and lever middle part near the joining float system of an end of cell body inboard by hinge and lever
B. valve system has the drawhole end and has the valve body casing of the gape that is complementary with the flotation device drawhole and the round-meshed box bottom that the outside is fixed in the casing base by being fixed on the flotation device cell body, the base is fixed in the ore discharge tube on the box bottom circular hole limit, and be fixed on round-meshed corner bracket in the casing and, upper end radially spacing by it and form at supermedial valve rod of lever and the valve body that is fixed on the valve rod lower end by hinge-coupled by the corner bracket circular hole
C. the float system by the fixing float sleeve of the support that is fixed on the valve body casing outside, be fixed in floater guiding frame in the float sleeve, upper end and form by the spacing float of floater guiding frame circular hole in lower end near the lever end points of cell body inboard by hinge-coupled.
The float upper end is provided with the handle (12) by the screw thread up-down adjustment.
The valve body that is fixed in the valve rod lower end can be platysome, also can be base and the affixed cone valve of valve thick stick.
Because flotation device ore pulp face self-con-tained unit of the present utility model can be finished automatic control to mineral syrup liquid, need not Artificial Control, and is rational in infrastructure, small investment can improve the yield of metal effectively, obtains desirable concentrate grade.
Description of drawings
Fig. 1 flotation pulp liquid level automatic control device figure.
The utility model is described in further detail below in conjunction with accompanying drawing.
Flotation device ore pulp face self-con-tained unit, by support (2) be fixed on flotation device cell body (1) outside by ore drawing oral-lateral top be fixed on the support lever pillar (3) and with the lever pillar with hinged lever (4), the float system that connects near an end of cell body inboard by hinge and lever is unified by the valve system composition that connects in the middle part of hinge and the lever.Valve system has the drawhole end and has and flotation device drawhole be complementary the valve body casing (5) of gape and the round-meshed box bottom (6) that the outside is fixed in the casing base by being fixed on the flotation device cell body, the base is fixed in the ore discharge tube (7) on the circular hole limit in the box bottom, and is fixed on round-meshed corner bracket (8) in the casing, and is connected through the hinge by its radially fixing upper end by the corner bracket circular hole and forms at supermedial valve rod of lever (9) and the valve body (10) that is fixed on the valve rod lower end.The float system is made up of the spacing float of floater guiding frame (13) in the lower end of the lever end of close cell body inboard by hinge-coupled the fixing float sleeve (14) of the support (11) that is fixed on the valve body sleeve outside, floater guiding frame (15), the upper end that is fixed in the float sleeve.
Float is provided with the handle by a chain for binding criminals line up-down adjustment.
During flotation device work, change as the ore pulp amount, can cause the ore pulp face to rise or decline when process conditions change.When liquid level rose, floating drum rose, and lever (A end) is moved up by power upwards, drive the valve rod that connects with lever middle part (B point), advance to wear moving valve plate and move up, the distance between valve plate and the ore discharge pipe is strengthened, the ore discharge ability increases, mineral syrup liquid can be satisfied gradually decline, floating drum also descends thereupon, and the distance between valve plate and gape diminishes, and then reduces the ore discharge amount, stop the continuation of ore pulp face to descend, thereby reach the effect of constant ore pulp face.The floating drum that has handle moves and can make its rising or decline by rotary handle, to determine the height of ore pulp face.After ore pulp face height is given, need not to carry out any adjusting work.Carry out any variation although feed the ore pulp amount in certain limit, the ore pulp face can both remain on the given height, has improved the metal yield widely and has made concentrate grade more reasonable.All mechanism and other parts are formed by general materials processing, and cost is low, and handling ease is easy to maintenance, and the control accuracy height of ore pulp face can satisfy the requirement of floatation process fully.
