Abstract
The utility model belongs to the technical field of automatic pressure filter pulling plates and particularly discloses a shower pipe lifting protection mechanism for the cloth washing vehicle of a pressure filter. The mechanism structurally comprises a driving shaft, a chain wheel fixed on the driving shaft, a driving shaft rotating speed signal mechanism and a coupler, wherein a buffer coupler corresponding to the coupler is fixed on the shaft extension of a motor; a photoelectric signal proximity switch for controlling the motor to rotate, decelerate or stall through an electronic control system is fixedly connected onto a frame; a water spray mechanism for cleaning the filter cloth of the pressure filter is fixed on the chain wheel through a chain. The protection mechanism is capable of controlling the motor to decelerate or stall when the water spray mechanism is prevented, and achieves lifting protection to the shower spray pipe for the cloth washing vehicle of the pressure filter.
Description
Technical field
The utility model belongs to filter press member technical field, relates to specifically a kind of membrane filter plate that is applicable to high squeeze pressure.
Background technology
Filter press is to be widely used in the visual plant that the industries such as chemical industry, oil, ore dressing, pharmacy, food realize solid phase and liquid phase separation, automatic pressure filter is a kind of high efficiency filter press of automatic discharging, in the course of work, first by being arranged at the oil cylinder of the one end of setting a roof beam in place, the filter plate in setting a roof beam in place is compressed, then product pump is delivered to solid-liquid compound in filter plate, clear liquid is discharged through filter cloth, and solid content is stayed and in filter chamber, formed filter cake.Oil cylinder unclamps, and the hydraulic motor of automatic pulling plate part drives chain drive arm-tie car to move back and forth, and filter plate is pulled open one by one, and the filter cake in filter chamber comes off, and completes discharging.After a plurality of circulations of filter press work, there is material particles to stop up filter cloth hole, the rate of filtration is obviously reduced, need to carry out high pressure washing to filter cloth.Current filter press automatic cloth washing vehicle mostly is a horizontal sparge pipe is set, and sidewall is equipped with a plurality of nozzles, sparge pipe upper and lower translation, and the water under high pressure of nozzle ejection hits filter cloth, removes and is embedded in the material particles in fiber cloth, recovers the strainability of filter cloth.This position that just requires cloth washing vehicle to stop is very accurate, makes sparge pipe lifting between two filter plates smoothly, once sparge pipe position is inaccurate, during decline, drop on filter plate, sparge pipe can not decline smoothly, can damage drive motors, even its counter-force causes cloth washing vehicle to be toppled over, generation equipment or personal injury.
Utility model content
The purpose of this utility model be just to provide a kind of can be when water spraying mechanism be prevented from, can control that rotary electric machine slows down or the filter-press cloth-washing car sparge pipe lifting protection mechanism of stall.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of filter-press cloth-washing car sparge pipe lifting protection mechanism; be characterised in that: comprise driving shaft and be fixed on sprocket wheel, drive shaft speed signaling gear and the shaft coupling on this driving shaft; the buffering coupling corresponding with this shaft coupling is fixed in the shaft extension of motor; photosignal approach switch by electric control system controls electric machine rotation, deceleration or stall is fixed in frame, for cleaning the water spraying mechanism of canvas press cloth, by chain, is fixed on sprocket wheel.
In addition, described drive shaft speed signaling gear is the inductive disks that is provided with some open-works.
A kind of filter-press cloth-washing car sparge pipe lifting protection mechanism provided by the utility model compared with prior art has the following advantages: one, owing to being provided with shaft coupling on the driving shaft that motor is driven, and when water spraying mechanism is prevented from, its coupling for driving shaft moving tooth and angular space between motor coupler moving tooth that forms shaft coupling can make moving tooth binding face depart from, thereby has provided the room and time condition of maintenance or the reset of sparge pipe elevating mechanism; Secondly; due to approach switch is fixed in frame; make this approach switch can gather and produce stable photoelectric pulse signal, and to the slow down control of stall of the click of rotating, realized the protection of the sparge pipe elevating mechanism to being formed by water spraying mechanism, chain and sprocket wheel.
Accompanying drawing explanation
Fig. 1: be the structural representation of filter-press cloth-washing car sparge pipe lifting protection mechanism;
Fig. 2: be the structural representation in inductive disks;
Fig. 3: the structural representation that cleans canvas press cloth water spraying mechanism;
Fig. 4: be the structural representation of coupling for driving shaft.
The specific embodiment
Below in conjunction with accompanying drawing, structure and the operation principle of filter-press cloth-washing car sparge pipe lifting protection mechanism provided by the utility model are described in further detail.
Be illustrated in figure 1 filter-press cloth-washing car sparge pipe lifting protection mechanism structural representation provided by the utility model, the structure that forms this protection mechanism comprises driving shaft 4 and is fixed on the sprocket wheel as shown in Figure 31 on this driving shaft, along the isometrical place of disk, be evenly provided with as shown in Figure 2 inductive disks 2 and the shaft coupling 7 of some open-works 12, the buffering coupling 5 corresponding with this half a coupler is installed in motor 6 shaft extensions 8, by electric-control system 13, control electric machine rotation, the photosignal approach switch 3 of deceleration or stall is fixed in frame 9, for cleaning the water spraying mechanism 10 of canvas press cloth, by chain 11, be fixed on sprocket wheel 1.
Its operation principle is starter motor, and motor drives drive shaft turns by shaft coupling, and the open-work in Fig. 2 inductive disks passes through approach switch successively, make it produce continuous pulse signal, electric-control system detects pulse signal, maintains electrical power, the normal lifting of sparge pipe.When sparge pipe surprisingly blocks, the driving shaft rotation that can not remain a constant speed, slows down or stops, and the inductive disks being fixed on driving shaft can not make approach switch produce pulse signal.When electric-control system detects signal intensity, make motor power-off.Simultaneously in Fig. 4, coupling for driving shaft moving tooth 14 rotating speeds reduce or stop, but motor coupler moving tooth 15 has angular space, itself and coupling for driving shaft moving tooth binding face depart from, during electric-control system detection, signal transmission, contactor action and motor braking, allow motor to be rotated further, unlikely generation mechanical shock.
In the structure of above-mentioned filter-press cloth-washing car sparge pipe lifting protection mechanism; the drive shaft speed signaling gear forming can be both the above-mentioned inductive disks that is evenly provided with open-work; also can adopt directly on driving shaft, arrange such as light signal generating mechanism; the control signal of controlling electric machine rotation is accepted and produced to this photosignal by approach switch; realization is controlled electric machine rotation; be beneficial to the room and time of maintenance or the reset of sparge pipe elevating mechanism, and realized the protection of the sparge pipe elevating mechanism to being formed by water spraying mechanism, chain and sprocket wheel.
