Description
Technical Field
The utility model relates to a feeder apparatus is thrown to lime breast is particularly suitable for mine neutralization reaction tank and uses.
Background
The lime is widely applied to industrial production of mineral separation, metallurgy, environmental protection and the like. Lime is generally prepared into lime milk, and then the lime milk is added into a reaction tank by using a transfer pump and a transfer pipeline. Because the calcium hydroxide of lime is slightly soluble in water, the lime milk is in the form of emulsion, and suspended matters in the lime milk can be adhered to the inner walls of a pipeline, a pump, a valve and a flowmeter in the lime milk conveying process, the problems of pipeline blockage, valve blockage, flowmeter failure and the like caused by scaling are solved.
Lime milk scaling is a problem that has plagued industrial production for a long time. The existing lime milk adding device is almost in a conveying mode of 'a conveying pump + a conveying pipeline', regular shutdown maintenance and descaling are usually adopted at present, internal scaling cannot be conveniently and effectively removed, the conveying pipeline has the characteristic of small and long bends, so that the inner diameter of the conveying pipeline is reduced to a certain degree and must be replaced, and even a pump or a pump head, a valve and a flowmeter are required to be replaced, so that the production cost is high.
Therefore, the development of the lime milk adding device has very important practical significance.
Disclosure of Invention
The utility model discloses a task is overcome prior art not enough, provides a feeder apparatus is thrown to lime breast, and it both can add by accurate measurement, can conveniently clear up the scale deposit again.
In order to complete the task, the novel use adopts the following technical scheme:
the lime milk adding device comprises a leaving transfer pump, a reserved flowmeter, a manual valve, an electric valve, a short-section transfer pipeline and an open channel; the short section conveying pipeline is sequentially provided with a manual valve, an electric valve and a flowmeter, and the conveying amount of the lime milk and the scale formation of the lime milk can be adjusted by adjusting the opening degree of the electric valve; the tail end of the short-section conveying pipeline is communicated with the head end of an arbitrary long-bent open channel to form a conveying channel, so that the descaling is facilitated; the lime milk storage tank is placed at the high end of the terrain drop, the bottom end of the lime milk storage tank is provided with the neutralization reaction tank, the head end of the short-section conveying pipeline is communicated with the lime milk storage tank, and the tail end of the open channel is low towards the neutralization reaction tank, so that the lime milk can automatically flow into the neutralization reaction tank.
Compared with the prior art, the beneficial effects of the utility model are that:
(1) simple structure, small equipment investment and low operation cost. The lime milk conveying system is arranged in a high-fall mode, a conveying pump is omitted, and equipment investment and operation cost are greatly reduced.
(2) The descaling operation is convenient, and the maintenance time is saved. The lime milk conveying channel adopting the short-section conveying pipeline and the open channel is short in pipeline and open in the open, scaling of the lime milk conveying channel can be greatly relieved, the lime milk conveying channel is easy to clean, and the service lives of the valve, the flowmeter and the pipeline are prolonged.
(3) The lime milk is accurately added. The opening of the electric valve can be accurately adjusted according to the actual lime milk demand, and the accurate feeding of the lime milk is realized.
Drawings
The specific structure of the utility model is given by the following drawings.
FIG. 1 is a schematic view of a main view of a device for adding lime milk according to the utility model.
The symbols in the drawings indicate:
1. lime milk storage tank 2, manual valve 3, electric valve 4, flowmeter 5, conveying pipeline 6, open channel 7 and neutralization reaction tank
The embodiments of the present invention will be described in further detail with reference to the accompanying drawings.
Detailed Description
As shown in figure 1, the lime milk adding device provided by the utility model comprises a delivery pump, a reserved flowmeter (4), a manual valve (2), an electric valve (3), a short-section delivery pipeline (5) and an open channel (6); the short section conveying pipeline (5) is sequentially provided with a manual valve (2), an electric valve (3) and a flowmeter (4), and the conveying amount of the lime milk can be adjusted and the lime milk is prevented from scaling by adjusting the opening degree of the electric valve (3); the tail end of the short-section conveying pipeline (5) is communicated with the head end of any long-bent open channel (6) to form a conveying channel, so that the descaling is facilitated; the lime milk storage tank (1) is placed at the high end of the terrain drop, the bottom end of the lime milk storage tank is provided with the neutralization reaction tank (7), the head end of the short-section conveying pipeline (5) is communicated with the lime milk storage tank (1), and the tail end of the open channel (6) is low towards the neutralization reaction tank (7), so that the lime milk can automatically flow into the neutralization reaction tank (7).
The utility model can be further
The manual valve (2) is normally open.
And the flow meter (4) and the electric valve (3) are subjected to PID feedback control, so that the quantitative feeding of the lime milk can be realized.
When in use, the lime milk storage tank 1 is placed at a position higher than the neutralization reaction tank 7, and the lime milk can automatically flow into the neutralization reaction tank 7 through the conveying pipeline 5 and the open channel 6 in sequence. The manual valve 2 is normally open. The conveying amount of the lime milk is adjusted by adjusting the opening degree of the electric valve 3. The lime milk delivery in real time can be observed by means of the flow meter 4. Quantitative feeding is realized through PID feedback control of the flow meter 4 and the electric valve 3. The electric valve 3 is operated to be fully opened or fully closed for 1-2 times every day, and the opening adjustment of the electric valve 3 is prevented from being influenced by lime milk scaling. When the scale is required to be cleaned or the machine is stopped temporarily, the manual valve 2 is closed, lime milk is stopped being conveyed, and the scale cleaning operation can be carried out on the positions of the electric valve 3, the flowmeter 4, the conveying pipeline 5, the open channel 6 and the like.
