Abstract
The utility model relates to an overflow-type filter cake washing device for a vacuum pan filter. The device is provided with a filter disc. A washing water overflow tank spanning the whole surface of the disc is horizontally arranged above the surface of the filter disc; a porous washing water supply pipe is transversely arranged above the washing water overflow tank; and the washing water supply pipe is connected with a water supply pipeline. When the overflow-type filter cake washing device for a vacuum pan filter washes a filter cake, the water flow is gentle, stable and balanced and the washing effect is good, so as to overcome the defect in the traditional washing method that the filter cake washing effect and the productivity are affected by concave-convex impact marks on the filter cake caused by washing water.
Description
Technical field
The utility model relates to a kind of vacuum horizontal table filter overflow-type filter cake wash mill.
Background technology
Present traditional vacuum horizontal table filter, its washing filter cakes mode is: uniform some arms in the washings service, at the end of each arm nozzle is installed, utilize high-pressure hydraulic that filter cake is washed.The major defect of this cleaning way is, can make to form concavo-convex impact impression on the filter cake, influences further clean result of filter cake and production capacity; And, utilize nozzle to wash, because its inner chamber of nozzle that is adopted is all smaller usually, and washings are not clear water usually, usually contain to have various mineral matters and soda acid etc., therefore cause spray nozzle clogging through regular meeting, the forfeiture washing function.
The utility model content
The technical problems to be solved in the utility model is: traditional vacuum horizontal table filter adopts the mode of high-pressure hydraulic flushing to washing filter cakes, existing easily makes filter cake form concavo-convex impact impression, influence further clean result of filter cake and production capacity, easily cause simultaneously flooding nozzle to stop up, the defective that causes the washing function forfeiture, for overcoming these defectives, provide a kind of vacuum horizontal table filter that has overflow-type filter cake wash mill.When the overflow-type filter cake wash mill of this machine cleans filter cake current releive, steadily, equilibrium, cleaning performance is good, can be to the filter cake impression that impacts.
The technical solution adopted in the utility model is: a kind of vacuum horizontal table filter overflow-type filter cake wash mill, it has filter disc, be provided with washings overflow launder in filter disc card upper horizontal across whole card, be horizontally arranged with the washings supply pipe of loose structure above the washings overflow launder, the washings supply pipe is connected with supply channel.
Can more releive, pour out on the filter cake from overflow launder reposefully in order to make washings, filter cake is releived, cleaned reposefully, and the described washings supply pipe that is horizontally set at washings overflow launder top has at least the body of half to be trapped in the vallecular cavity of washings overflow launder; And its groove of washings overflow launder is along having downward-sloping draining board.
Described washings overflow launder is supported by the formula the heightened bracing frame that is arranged on its two ends, and the levelness that can regulate the washings overflow launder thus to improve the uniformity of overflow, improves clean result.
The beneficial effects of the utility model are: when the overflow-type filter cake wash mill of this vacuum horizontal table filter cleans filter cake current releive, steadily, equilibrium, cleaning performance is good, the washing current can not make the concavo-convex impact impression of formation on the filter cake, and do not use nozzle yet, do not have blockage problem; Compare with the filter cake wash mill of traditional vacuum horizontal table filter simultaneously, also saved high-pressure hydraulic pump, reached energy-conservation effect.The operation and maintenance cost of complete machine also reduces greatly.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of washings overflow launder in the utility model.
1. filter cakes, 2. washings overflow launders, 3. washings supply pipes 4. can be heightened the formula bracing frame among the figure
The specific embodiment
As shown in Figure 1, a kind of vacuum horizontal table filter overflow-type filter cake wash mill, it has filter disc 1, be provided with washings overflow launder 2 in filter disc 1 card upper horizontal across whole card, be horizontally arranged with the washings supply pipe 3 of loose structure above washings overflow launder 2, washings supply pipe 3 is connected with supply channel.
The whole washing process of overflow-type filter cake cleaning device is: washings enter the washings supply pipe of loose structure, flow into the washings overflow launder from aperture, overflow launder washed water completely back flows on the card of rotation along the draining board that tilts by groove, and filter cake is washed.During washing, washings supply pipe major part is submerged in the washings in the overflow launder, can guarantee that so whole overflow launder overflow releives, steadily.In addition, what be provided with at washings overflow launder two ends is height-adjustable bracing frame, but the levelness of the whole overflow launder of two bracing frame fit adjustment to guarantee that washings evenly flow to the filter cake card, reaches fully effectively clean result.
