Abstract

The utility model discloses equipment for treating residue of aluminium phosphide, which is provided with a reaction tank [15] covered by a movable upper cap [1] with venting holes [2], a valve well [10] and a water reservoir [16]. The utility model is characterized in that a layer of filtering layer [5] is arranged in the reaction tank [15], a run-off pit [7] with a catchment slope [8] is positioned under the filtering layer [5], the run-off pit [7] is provided with a cover [6] on it, a drainage pipe [9] arranged in the run-off pit [7] is communicated with the water reservoir [16] through a valve [14], and a back-flushing pipe [3] is connected to the drainage pipe in the front of the valve [14]. The advantages of the equipment are that the residue of aluminium phosphide is sealed in concentrated manner for short reaction time and steady treatment, and the content of hydrogen phosphide in waste residue and waste water after treatment is approximate to 0 or equal to 0 ppm which completely reaches the specified emission standard. Compared with the old methods of underground deep-burying and wantonly washing away by water, this equipment not only saves the manual work and reduces the occupying area, but also has the profound significance of environmental protection.

Description

A kind of aluminum phosphate residue treatment device

Technical field

The utility model belongs to grain and stores the device that pesticide and disinfectant is handled, particularly a kind of aluminum phosphate residue treatment device.

Background technology

Utilize aluminum phosphate and the reaction of airborne water to generate the technology of phosphine as fumigant control silo grain storage pest in China, have the history in year surplus in the of 40, other means of prevention occur up to also not having better at present.Aluminum phosphide tablet is one of widely used formulation in storage practice, adds the auxiliary agent compacting with the former powder of aluminum phosphate and forming, and has the characteristics easy to use of transportation and is used widely.When this tablet after natural deliquescence method is handled silo, there is the aluminum phosphate of 3-5% not decompose fully approximately, and formation aluminum phosphate residue, past is to adopt buried undergroundly always, and its natural decomposition was lost efficacy, and along with the development and progress of country, it is fewer and feweri to plough, can be also fewer and feweri for buried place, sclerosis has generally all been passed through in the place, reservoir area of grain depot and greening is handled, and can almost not have for buried place in the grain storage reservoir area.And year by year adjacent local buried, inevitably can be underground with imbedding in the past, but the aluminum phosphate residue that also is not able to do in time to decompose fully digs, and closer from the face of land, form secondary pollution easily.Had once also that the people is irresponsible to be washed away it along sewer with water, the serious consequence that causes like this is conspicuous.In order to overcome these problems, the residue of aluminum phosphate is carried out effective harmless treatment, goal of the invention of the present utility model has been proposed.

Summary of the invention

In order to solve the innocuity treatment problem of remaining aluminum phosphate residue behind the silo grain storage fumigation control insect, goal of the invention of the present utility model has been proposed.Goal of the invention of the present utility model provides a kind of aluminum phosphate residue treatment device.This device has a reaction tank [15] that is covered with have ventilation hole [2] and transportable loam cake [1] on it, a valve well [10] and a storage cistern [16], the inside that it is characterized in that reaction tank [15] has one deck filter course [5], it below the filter course [5] a run-off [7] with the slope of catchmenting [8], has a lid [6] above the run-off [7], there is a drainpipe [9] to be communicated with storage cistern [16] in the inside of run-off [7], on the drainpipe of valve [14] front end, connects a recoil tube [3] by valve [14].A Here it is complete aluminum phosphate residue treatment device, by this device, concentrate sealing to handle the aluminum phosphate residue, the reaction time is short and stable, waste residue after the processing and the phosphine content in the waste water approach 0 or equal 0ppm, reach the discharge standard of regulation fully.Than methods such as buried underground and irresponsible careless water in the past wash away, not only saved manually but also reduced appropriation of land, can reach the requirement of phosphine zero-emission fully, have the very high value of environmental protection.

Description of drawings

Accompanying drawing is a structural profile view of the present utility model, and the meaning of sequence number in the accompanying drawings is: 1, loam cake, 2, ventilation hole, 3, recoil tube, 4, pool wall, 5, filter course, 6, lid, 7, run-off, 8, the slope of catchmenting, 9, drainpipe, 10, valve well, 11, the valve well lid, 12, pond, 13, pond cover, 14, valve, 15, reaction tank, 16, storage cistern.

Embodiment

Below in conjunction with the specific embodiment in the accompanying drawing, the utility model is described in detail.With reference to accompanying drawing, this device has a reaction tank [15] that is covered with have ventilation hole [2] and transportable loam cake [1] on it, a valve well [10] and a storage cistern [16], the inside that it is characterized in that reaction tank [15] has one deck filter course [5], it below the filter course [5] a run-off [7] with the slope of catchmenting [8], having a lid [6] above the run-off [7] has a drainpipe [9] to be communicated with storage cistern [16] by valve [14] in the inside of run-off [7], connect a recoil tube [3] on the drainpipe of valve [14] front end.During use, collected aluminum phosphate residue is ready to, removes loam cake, the aluminum phosphate residue is poured in the reaction tank [15], put into an amount of water then, (the residue surface that generally should there be aluminum phosphate is with fast reaction speed.) cover loam cake [1] rapidly, generally through the content of measuring the phosphine that ventilation hole [2] locates in 12 hours below 0.2ppm, continue reaction, through 24 hours, the phosphine content that ventilation hole [2] is located did not detect.After reaction finished, remaining aluminium hydroxide, carbamate also had material such as dolomol to leave in the reaction tank [15], and these materials have not had harm to environment and other animals and plants, can be according to its standard-required discharging separately just.Through the water of reaction, below the inner filter course [5] of reaction tank [15] being penetrated into gradually, through the slope of catchmenting [8], enter into run-off [7] inside, when water increases gradually, when not having drainpipe [9] suitable for reading, just flow in the storage cistern [16] through valve [14] along pipeline.After whole reaction water has been arranged, with recoil tube [3] cut-in pressure water, valve [14] is washed again, to remove the dirt of valve internal, valve-off [14], and valve-off well lid [11] and storage cistern lid [13], the water that these reacted, can stay in the storage cistern always, (bottom of common storage cistern for the sealing promptly can) recycle when treating to handle the aluminum phosphate residue next time, if the amount of the residue of the aluminum phosphate of handling is little, also can filter course [12] be set in the bottom of storage cistern according to the version in the accompanying drawing.Reacted water is directly penetrated into underground getting final product.Provided the embodiment of simple brick mix structure in the accompanying drawing, if it is produce in batches and, can adopt stainless steel and plastic material to make whole equipment, high many but cost is wanted as main material as commercial application.Whole device can be on the ground, also can be semi-underground device.
