Description

The adhesive tape type feeder

Technical field

The utility model relates to the quantitatively feeder of the specialized equipment, particularly a kind of charged sub-gauging device of defeated coal of a kind of thermal powerplant, cement mill, steel plant.

Background technology

Feeder is the quantitatively specialized equipment of defeated coal of thermal powerplant, cement mill, steel plant.Its traditional approach is to use scraper feeder.Because raw meal particle size is big, have corrosive property, the carrier bar serious wear influences the service life and the reliability of feeder.A feeder will be changed a carrier bar in per three to six months, and productive costs is increased, and maintenance load increases.

Summary of the invention

In order to overcome the shortcoming of prior art, the utility model provides a kind of failure-free gauging device.By adopting the adhesive tape convey materials to replace scraper plate, increase the feeder of electronic weighing instrument.

Design plan of the present utility model is achieved in that a kind of adhesive tape type feeder, by housing, drive motor, drive roll, passive cylinder, endless-belt, LOAD CELLS and gauging device, speed measuring device, elevating hopper, hopper, hermatic door, access door, the cleaning motor, clearing apparatus, illuminating lamp, return idler, prop up and be configured to, it is characterized in that: housing adopts totally-enclosed pressure-resistance structure, drive roll, passive cylinder is assembled on the housing by bearing seat, endless-belt is propped up by drive roll and passive cylinder and carrying roller, the drive motor direct connection is at the drive roll axle head, during the motor operation, drag the belt operation; Elevating hopper, hopper are welded on the housing, hermatic door, access door are installed on the housing by bolt, the cleaning motor is connected in clearing apparatus by axle drive shaft and is installed in lower housing portion, clearing apparatus adopts double-stranded bar belt scraping plate respectively, double-stranded bar is assembled on the same axle drive shaft, illuminating lamp is installed on the housing, and return idler is installed on frame.Speed measuring device is made of coder and housing, is installed on the passive drum shaft.Gauging device is made up of LOAD CELLS and weighing carrying roller, and metering carrying roller axle head is connected on the preceding end connection of LOAD CELLS.

The utility model has the advantages that: the drive disk assembly service life that prolongs feeder; Improve the control accuracy of measuring accuracy and coal-supplying amount, make the measuring accuracy of feeder increase by 3 to 5 times; Fracture can be installed, and the operation of warning device formula feeders such as putty is more reliable; Adopt electronic weighing device, but control cabin direct control feeder has improved the automatic guidance degree.

Description of drawings

Below in conjunction with drawings and Examples the utility model is described further.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a lateral plan of the present utility model;

Fig. 3 is a control part schematic diagram of the present utility model.

The specific embodiment

Feeder is the key equipment of industrial and mining enterprises' coal handling system.Its groundwork is: the weight signal on the belt is applied on the LOAD CELLS, and LOAD CELLS is transformed into electric signal (mV) with weight signal; Simultaneously, belt speed is detected by velometer, and velometer is transformed into impulse singla with speed signal.Display instrument is made product calculation with weight signal and speed signal, shows the instant flow rate of band conveyor.Again instant flow rate is done the accumulative total computing, the cumulative amount of reflection feeder convey materials.

The adhesive tape type feeder is by housing 1, drive motor 2, drive roll 3, passive cylinder 4, endless-belt 5, LOAD CELLS and gauging device 6, speed measuring device 7, elevating hopper 8, hopper 9, hermatic door 10, access door 11, cleaning motor 12, clearing apparatus 13, illuminating lamp 14, return idler 15, be configured to 16.

Housing 1 adopts totally-enclosed withstand voltage formula structure; Drive roll 3, passive cylinder 4 are assembled on the housing 1 by bearing seat, and endless-belt 5 is propped up by drive roll and passive cylinder and carrying roller, and drive motor 2 direct connections during the motor operation, drag the belt operation at the drive roll axle head.Elevating hopper 8, hopper 9 are welded on the housing, hermatic door 10, access door 11 are installed on the housing 1 by bolt, cleaning motor 12 is connected clearing apparatus 13 by axle drive shaft and is installed in lower housing portion, be used for cleaning the salvage stores that falls on interior laying dust of housing and the belt, clearing apparatus adopts double-stranded bar belt scraping plate respectively, double-stranded bar is assembled on the same axle drive shaft, illuminating lamp 14 is installed on the housing, illumination when being used to overhaul, return idler 15 is installed on frame, be used to hold up return belt, support 16 is used to install the feeder body.

Gauging device 6 is made up of UB2 type LOAD CELLS and weighing carrying roller.Metering carrying roller axle head is connected on the preceding end connection of LOAD CELLS, and when the metering carrying roller bore weight, LOAD CELLS was stressed, and gravitational cue is transformed into electric signal output.

Speed measuring device (7) is made of TV 150N type coder and housing.Be installed on the passive cylinder spindle nose.Passive cylinder revolution moves a week, drives speed measuring coder and rotates a week, sends 1000 pulses, the length of the belt operation that each pulse representative is fixing.

The display control section of weighing is finished by the secondary display instrument.As shown in Figure 3, the weighing-up wave of LOAD CELLS output amplifies through amplifier, and A/D converts digital quantity to and is transported to CPU element; The LOAD CELLS output pulse signal is transported to CPU after shaping; Each impulse singla causes that CPU interrupts once, and the A/D sampled value is deducted the zero point value again divided by adding up behind the coefficient of ranger, calculates instant flow rate value and aggregate-value.
