Description
Technical Field
The utility model relates to the field of vertical vacuum disc filter equipment, in particular to a forced liquid discharge valve.
Background
The factory production requires equipment to run as full as possible, and can be used completely, but the load utilization rate of practical equipment is mostly less than 70%, the vertical disc filter sucks the attached water in the filter cake into the forced liquid discharge tank through the vacuum negative pressure provided by the water ring vacuum pump, the forced liquid discharge tank is controlled to discharge liquid through the forced liquid discharge valve, the forced liquid discharge tank is not thoroughly discharged due to the fact that the opening of the air discharge tank of the forced liquid discharge valve is smaller, the efficiency is low, the backwater amount is less, and the adsorption effect of the filter is affected by checking about 1/3 of the volume of the forced liquid discharge tank for each liquid discharge.
Disclosure of Invention
The utility model provides a forced liquid discharge valve.
In order to achieve the above purpose, the present utility model adopts the following technical scheme:
the forced liquid draining valve comprises a valve body, wherein the valve body comprises a vent disc and an air staggering disc, the vent disc and the air staggering disc are connected by bolts in a matched manner through a central bolt hole, the vent disc comprises a vacuum vent hole and an air vent hole, the vacuum vent hole comprises a vent hole I, a vent hole II and a vent hole III, the air staggering disc comprises a vent groove,
further, the first vent hole, the second vent hole and the third vent hole are annularly distributed on the vent disc,
further, the first vent hole, the second vent hole and the third vent hole are communicated with a vacuum pipeline,
further, the first air vent is connected with the left tank of the liquid discharge tank, the second air vent is connected with the upper tank of the liquid discharge tank, the third air vent is connected with the right tank of the liquid discharge tank,
further, the vent grooves comprise a vent groove I and a vent groove II.
The beneficial effects are that: when the filter works, the vacuum pump provides vacuum negative pressure for the filter, the forced liquid discharge valve sucks the attached water in the filter cake into the forced liquid discharge tank, and the ventilation time of the forced liquid discharge tank is prolonged by widening and lengthening the ventilation groove, so that the liquid discharge time is prolonged.

Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.
In the description of the present utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," "outer," and the like indicate or are based on the orientation or positional relationship shown in the drawings, merely to facilitate description of the present utility model and to simplify the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present utility model.
Referring to fig. 1-2, a forced drain valve comprises a valve body, the valve body comprises a vent disc 3 and an air staggering disc 1, the vent disc 3 and the air staggering disc 1 are connected with each other through a central bolt hole 5 in a bolt fit manner, the vent disc 3 comprises a vacuum vent hole 4 and an air vent hole 6, the vacuum vent hole 4 comprises a vent hole one 401, a vent hole two 402 and a vent hole three 403, the air staggering disc comprises a vent groove 2,
the first ventilation hole 401, the second ventilation hole 402 and the third ventilation hole 403 are distributed on the ventilation disk in a ring shape,
the first vent 401, the second vent 402 and the third vent 403 are communicated with a vacuum pipeline,
the first air vent 401 is connected with the left tank of the liquid discharge tank, the second air vent 402 is connected with the upper tank of the liquid discharge tank, the third air vent 403 is connected with the right tank of the liquid discharge tank,
the ventilation groove 2 comprises a ventilation groove I and a ventilation groove II.
Working principle:
when the forced liquid discharge valve in the filter is stationary, the first ventilation groove on the left side of the air-staggering disc 1 is communicated with the first ventilation hole 401 and the second ventilation hole 402 on the left side of the air-staggering disc 3, and the second ventilation groove on the right side is communicated with the third ventilation hole 403 and the air ventilation hole on the right side of the air-staggering disc 3.
When the forced liquid discharge valve in the filter works, the forced liquid discharge valve drives the air-staggering disc 1 to rotate, the first vent groove on the left side of the air-staggering disc 1 is communicated with the first vent hole 401 and the second vent hole 402 of the air-staggering disc 3 to be communicated with the second vent hole 402 and the third vent hole 403 in the air-staggering disc 3, liquid is not discharged because the forced liquid discharge valve is in a vacuum state, meanwhile, the rotation of the second vent groove on the right side is communicated with the first vent hole 401 and the air vent hole through the third vent hole 403 and the air vent hole of the air-staggering disc 3, so that air is communicated with the first vent groove through the air vent hole on the right side, the first vent groove loses vacuum to further enable the liquid discharge barrel on the left side of the forced liquid discharge pot to lose vacuum, and the vacuum gate is pressed to discharge liquid under the gravity of liquid in the pot.
When the filter works, the vacuum pump provides vacuum negative pressure for the filter, the forced liquid discharge valve sucks the attached water in the filter cake into the forced liquid discharge tank, and the ventilation time of the forced liquid discharge tank is prolonged by widening and lengthening the ventilation groove, so that the liquid discharge time is prolonged.
The foregoing is only a preferred embodiment of the present utility model, but the scope of the present utility model is not limited thereto, and any person skilled in the art, who is within the scope of the present utility model, should make equivalent substitutions or modifications according to the technical scheme of the present utility model and the inventive concept thereof, and should be covered by the scope of the present utility model.
