Abstract
The utility model discloses a stifled alarm device is prevented to mud backwash pump, including the backwash pump, the one end of backwash pump is connected with the grid screen cloth, and the one end that the grid screen cloth was kept away from to the backwash pump is connected with the flowmeter, and the inside of backwash pump is provided with the converter. The utility model discloses can use manpower sparingly material resources, needn't salvage the sludge pump again and come manual the decontamination to the device can in time discover below grid screen cloth rubbish through alarm device and block up too much, thereby can in time clear up, when solving the sludge reflux pump and being blocked up, power consumptive height, the little problem of flow also can be more audio-visual in real time to know the sludge reflux volume in two heavy ponds.
Description
Technical Field
The utility model relates to a sewage treatment technical field especially relates to a mud backwash pump prevents stifled alarm device.
Background
In the actual operation of a sewage treatment plant, when an anaerobic-anoxic-aerobic process (A2O) is used, the water flow is large, the large pool surface inevitably causes white garbage, maintenance, gloves of operating workers and other garbage to enter a sewage treatment system after the grating, so that a sludge reflux pump at a secondary sedimentation tank is frequently blocked, and the blockage removal work consumes manpower and material resources. And this problem is difficult to detect during operation due to the reflux pump being underwater.
A method for preventing a sludge reflux pump of a secondary sedimentation tank from being blocked in a moving bed biofilm reactor process (MBBR) is used for intercepting fillers in the MBBR and is not suitable for A2And (4) in the O process. Since the fillers intercepted in the MBBR process do not require treatment, only interception is required, whereas in A2What is intercepted in the O process is that the garbage needs to be cleaned in time. Otherwise, the sludge reflux pump can not pump enough sludge, the reflux is small, and the electricity is wasted, so that the operation cost is increased
Original mud reflux unit has the drawback, because original inhale mud and for directly advance mud from the pipeline and can cause the mud backwash pump to seriously block up when debris and white rubbish are more in the backward flow mud to this condition is hardly found when the operation, can cause a series of chain reaction such as mud backward flow not enough.
SUMMERY OF THE UTILITY MODEL
For overcoming the problem that exists among the correlation technique, the embodiment of the utility model provides a stifled alarm device is prevented to mud backwash pump solves mud backwash pump when stifled, and power consumptive height, the little problem of flow.
The embodiment of the utility model provides a stifled alarm device is prevented to mud backwash pump, including the backwash pump, the one end of backwash pump is connected with the grid screen cloth, and the one end that the grid screen cloth was kept away from to the backwash pump is connected with the flowmeter, and the inside of backwash pump is provided with the converter.
Furthermore, the grid screen is a basket-shaped grid screen, and the outside of the grid screen is of a frame structure.
Further, the inner screen of the grille screen is successively smaller in size from the direction of the water inlet.
Furthermore, the frequency converter is connected with an alarm device through an electric wire, and the alarm device is connected with the flowmeter.
Furthermore, a thermometer is arranged in the reflux pump and connected with an alarm device.
The embodiment of the utility model provides a technical scheme has following beneficial effect: can use manpower sparingly material resources, needn't salvage the sludge pump again and come manual the filth removal to the device can in time discover below grid screen cloth rubbish through alarm device and block up too much, thereby can in time clear up, when solving the sludge reflux pump and being blocked up, power consumptive height, the little problem of flow also can be more audio-visual in real time know the sludge reflux volume in two heavy ponds.
It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention as claimed.
Drawings
The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the invention and together with the description, serve to explain the principles of the invention.
FIG. 1 is a schematic structural view of an anti-blocking alarm device of a sludge reflux pump of the embodiment of the utility model.
Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus, and associated applications, methods, consistent with certain aspects of the invention, as detailed in the following claims.
FIG. 1 is a schematic structural view of an anti-blocking alarm device of a sludge reflux pump of the embodiment of the utility model. As shown in figure 1, this anti-blocking alarm device of sludge reflux pump, including backwash pump 2, the one end of backwash pump is connected with grid screen cloth 1, grid screen cloth is basket form grid net, the grid screen cloth outside is frame construction, grid screen cloth can effectively prevent rubbish to get into the backwash pump, grid screen cloth can the motor-driven operation, the accessible is from the accuse, the automatic start of grid cleaning, grid screen cloth's inside screen cloth diminishes from the direction sieve mesh of rivers import in proper order, inside screen cloth can conveniently carry out the clearance to inside screen cloth with the separation of outer frame, thereby play the problem that prevents the pump stifled, the clearance has been made things convenient for again.
The one end that the grid screen cloth was kept away from to the backwash pump is connected with flowmeter 6, the inside of backwash pump is provided with converter 4, the converter has alarm device 5 through the connection of electric lines, alarm device is connected with the flowmeter, when the frequency of water flow and backwash pump differs great, just can trigger alarm device, the backwash pump also can be connected with programmable logic controller remote control device, can remote monitoring, it is less when water flow, also can carry out on-the-spot trash cleaning when the frequency is great, can realize simultaneously that the mud backward flow volume is looked over in well accuse room is long-range, and can contrast the frequency of backwash pump, be convenient for operation management and can become the manpower and materials that reduce sewage treatment mutually.
The inside of backwash pump is provided with thermometer 3, and the thermometer is connected with alarm device, also can trigger alarm device when the temperature surpasss the normal operating temperature of motor, can effectually prevent to arouse the damage of pump because of anterior jam water pump idle running like this.
The use flow of the anti-blocking alarm device for the sludge reflux pump is described below.
And starting the reflux pump, allowing the sludge to flow to the reflux pump through the grid screen, and remotely checking the sludge reflux amount in the central control room.
When the frequency difference between the water outlet flow and the pump is large, the flow meter transmits the change of the flow to the frequency converter, the alarm device is triggered immediately, and the grating screen is started to automatically clean.
Meanwhile, the thermometer monitors the temperature change of the reflux pump in real time, and the alarm device is triggered when the temperature exceeds the normal operation temperature of the motor, so that the reflux pump stops operating.
Other embodiments of the invention will be apparent to those skilled in the art from consideration of the specification and practice of the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of the invention following, in general, the principles of the invention and including such departures from the present disclosure as come within known or customary practice within the art to which the invention pertains.
