Description
1, technical field:
The utility model relates to a kind of be applied to can finish in the chemical industry filtration of crystallization suspension, the crystal washer of washing, the filtration of inorganic salts crystallization suspensions such as particularly a kind of potassium nitrate, sodium nitrate, sodium chloride, ammonium chloride, the crystal washer of washing.
2, background technology:
In production of inorganic technologies such as potassium nitrate, sodium nitrate, sodium chloride, ammonium chloride, crystallization suspensions such as potassium nitrate, sodium nitrate, sodium chloride, ammonium chloride need filter and divide the mother liquor of leaving away, to filter the gained crystal product again washs with wash water, behind the washing crystal surface impurity, be sent from the scheming centrifugal dehydration again, to obtain satisfactory product.
At present, usually adopt the open type filter to finish the filtration and the washing of crystallization suspension, this filter filter cloth, filter are as filter medium, the crystallization suspension that to squeeze into filter earlier filters, after dividing most of mother liquor of leaving away, add clear water again and soak, by manually stirring feed liquid (also have logical compressed air to stir and stir feed liquid), to strengthen clean result, deliver to centrifuge by artificial conveyance (also useful submerged pump is pumped) then and carry out separating and dehydrating crystal product.This open type filter has the following disadvantages: the one, and clean result is poor, and the washing water yield is big; The 2nd, product is easily sneaked into introduced contaminants and is contaminated; The 3rd, labour intensity is big, and production capacity is low.
China's utility model patent 00236035.7 discloses a kind of " two-in-one crystal filter ", but the structure more complicated, and because filter cloth directly is layered on above the filter plate, only depend on ring to compress the filter cloth periphery, mid portion directly contacts with material, and in the operating process, filter cloth is easy to damage.
3, goal of the invention:
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of airtight crystal washer that can integrate filtration, wash is provided, have simple in structure, filtration washing is effective, filter cloth long service life, characteristics such as simple to operate.
4, summary of the invention:
The technical scheme that realizes above-mentioned purpose and adopt comprises:
1. the bulge shell is cylinder, and cylinder is provided with wash water inlet tube and vomit pipe, also be provided with the compressed air inlet pipe on the vomit pipe, also be provided with 1 manhole and stiffening ring on the cylinder, stiffening ring at cylinder topmost, be generally angle ring, its material carbon steel.
2. container floor, base plate is a circular slab, is built in the cylinder, weld with cylinder, several gussets are set under the base plate, are used for bearing plate and strengthen the welding drum body, gusset and support plate welding, support plate is for being horizontally disposed with, be square or circle, be used to support the entire equipment device, root a tree name apparatus weight and size, support plate generally will be provided with more than 3 at least, and base plate bottom also is provided with filtrate exit pipe.
3. container cover plate, cover plate is a circular slab, is provided with bearing support above the cover plate, bearing support is welded to form by channel-section steel and steel plate, and bearing support is used for fixing frame, also is provided with feed pipe, clear water inlet tube and 2 hand holes on the cover plate, feed pipe extend in the container near the cylinder limit always.
4. the bottom is provided with the filter screen dish in the container, the rounded shape of filter screen dish, and its diameter is slightly less than the cylinder internal diameter, so that install and move up and down in container.Laminated plank was formed under the filter screen dish was reached by last laminated plank, screen cloth, all was provided with equally distributed filter opening on the laminated plank of last laminated plank up and down, and screen cloth is provided with 1 to 4 layer usually, and last laminated plank relies on self gravitation and the effect of crystallization suspension gravity to compress screen cloth.Filter screen dish bottom is provided with the filter screen disc carrier, and the filter screen disc carrier is welded on cylinder and the bottom surface, is used to support the filter screen dish.
5. on the container center axis agitating device is housed, agitating device is made up of 2 groups of agitators, shaft, seal box, shaft joint, frame, reductors, the effect of agitator is an agitator treating of realizing container inner medium, increases the media flow performance simultaneously and is convenient to blowing, on the frame fixed supporting frame.Following agitator lowermost portion is near the filter screen dish, so that stir discharge.
6. 2 hand holes are distributed in the bearing support both sides, on the cover board are symmetric arrays, hand hole can be airtight with open, manhole also can be airtight with open, it is to make things convenient for the workman to enter maintenance that manhole mainly acts on.When changing the filter cloth operation, after needing earlier agitator to be dismantled, the last laminated plank with the filter screen dish is suspended to the container internal upper part by hand hole with rope again.
7. the vomit pipe minimum point flushes with plane on the container Inner filter net dish, so that the material discharging is clean.Manhole is on filter screen dish top, and its minimum point is near container Inner filter net dish.This installs its material and is mainly stainless steel or carbon steel.
The course of work:
The first step, the crystallization suspension filters.Close the vomit pipe valve, closes compression air intlet tube valve is closed wash water inlet tube valve.Open the filtrate (liquid tube valve, open the feed pipe valve, the crystallization suspension is flowed in the container by feed pipe, mother liquor is through filter screen dish isolated by filtration in the crystallization suspension, flow to mother liquor tank through filtrate exit pipe, crystal (filter residue) is trapped in the container, treats that crystal reaches certain thickness, close the feed pipe valve, stop charging.When filtrate exit pipe does not have the filtrate outflow substantially, close the filtrate (liquid tube valve.
Second step, the crystal washing.Open wash water inlet tube valve, add washings from the bottom in container, washings are submergence crystal from bottom to up slowly, during crystal, closes wash water inlet tube valve in the complete submergence container of washings.Start mixer, mixer is the interior crystal of agitator treating container at a slow speed.
The 3rd step, blowing.Open the vomit pipe valve, the crystal feed liquid in the container is discharged, be sent from the scheming centrifugal dehydration.Under stirring condition, feed liquid generally can not stopped up, if stop up, then opens the compressed air inlet tube valve, blow with compressed air stifled, till eliminate stopping up, closes compression air intlet tube valve again.After feed liquid has been put, open cover plate supernatant water inlet tube valve, add proper amount of clear water washing container Inner filter net dish, and the clean deposition material, washings are discharged in the lump through vomit pipe, close clear water inlet tube valve then, close the vomit pipe valve, close down agitator.
Behind the above end of operation, carry out next cycling.
5, invention advantage:
The utility model compared with prior art has the following advantages:
1. this apparatus structure is simple, easy to operate, because last laminated plank compresses screen cloth, in the operating process, screen cloth is not fragile, the screen cloth long service life, thus overcome the deficiency of Chinese utility model patent 00236035.7.
2. this device is easy for installation, but the level land installation, but also flooring is installed.
3. owing to the moving up property of filter screen dish, the workman enters maintenance and replacing filter cloth etc., and operation is very easy.
4. adopt to add rinse water from the bottom, filter cloth that on the one hand can backwash filter screen dish improves filter effect, and on the other hand, in the submergence container during crystal, its water distribution and clean result are good from the bottom up for clear water.
5. this device is provided with compressed air and blows stifledly, has solved incident clogging in the blowing process well.
