Abstract

The utility model provides an efficient intelligent automatic preparation device of PAM (polyacrylamide), consisting of a dry powder metering and injecting device with a heating function, a high-speed water and powder mixer, a dissolving box, a curing box and a storing box. The intelligent automatic preparation device of the PAM is characterized in that PAM dry powder is accurately metered through the dry powder metering and injecting device with the heating function; the metered water enters the high-speed water and powder mixer to be rapidly mixed; the mixed PAM enters the dissolving box to be rapidly dissolved; the curing effect of PAM solution can be realized through the curing box; and the prepared PAM solution enters the storage box for future use. The intelligent automatic PAM preparing device provided by the utility model has the advantages of reasonable design and simple structure, and is the efficient solution preparing device with good dissolving effect, accurate metering and less manual operation volume.

Description

Polyacrylamide intelligence automatic preparing device

One, technical field

The utility model is the high polyacrylamide of a kind of automaticity (PAM) solution preparation device, can be widely used in the medicament device for formulating that use in the fields such as environmental protection, chemical industry, water treatment.

Two, background technology

In the medicament device for formulating that use in the fields such as chemical industry, environmental protection, water treatment, often to use dry powder preparation liquid medicine.Traditional dry powder solution preparation device will manually regularly be prepared, and the shortcoming of artificial obtain solution has: (1) solution concentration and solution quality can't stablize, accurately, and the dissolving of PAM requires the weighing accurately of dry powder, and the time that solution stirs must meet the demands.So excessive concentration often occurred or crossed low can't the use by the PAM solution that manually makes, the mixing time deficiency causes dry powder also not dissolve fully and causes active constituent content excessively low, just can't use after PAM dry powder makes moist simultaneously; (2) the manual work amount is larger, and traditional dissolving case all is related to higher vertical cabinet, and higher operating platform is arranged, so need manually packaging bag to be transported on the platform before preparation, also needs manually to carry out weighing during metering; (3) personnel's unexpected injury.Some dry powder has injury to personnel, and perhaps solution can be corrosive.PAM dry powder is met water can be very sliding, and solution causes personnel's the generation unexpected injury of falling.At present some are also arranged to the modifying device of traditional dissolver, but also exist the metering of PAM inaccurate, the situation such as solute effect is bad, the slaking effect is bad.

Three, utility model content

Technical problem to be solved in the utility model is, solves the problem of above-mentioned PAM dissolving preparation, and a kind of reasonable in design, simple in structure, PAM dissolving device for formulating that result of use is good is provided.

Technical solutions of the utility model are: polyacrylamide intelligence automatic preparing device comprises that the dry powder of band heating measures throwing device, high speed solid-liquid blender, dissolving case, curing box, storage bin; It is characterized in that: the dry powder metering throwing device of (1) band heating is provided with the VFC auger conveyor that adds polyacrylamide dry powder: by changing the amount of VFC conveying worm electric machine frequency control conveying worm output dry powder, thereby control flexibly the proof dry powder feeding amount, the auger conveyor outlet is provided with electric heater unit, guarantees that conveying worm exports moist obstruction that can not become because of the steam that rises; High speed solid-liquid blender is on the top of dissolving case; High speed solid-liquid blender is the mixer structure in the dissolving case; Be provided with curing box and storage bin behind the dissolving case, be provided with the curing box mixer.(2) the mixer structure in the high speed solid-liquid blender dissolving case, mixer produces high-velocity flow: high-velocity flow enters along the blender tangential direction after conveying worm metering output, form high speed whirlpool state, dry powder has just been realized rapid mixing after entering the water whirlpool; (3) device of dissolving case, curing box, storage bin integrated front and back distribution is provided with the curing box mixer, realizes effectively dissolving, slaking by rational control flow state.Dissolving case and curing box are provided with agitating device, and reasonably design guarantees abundant and good mixing effect.Too fast or excessively slow stirring all is unfavorable for dissolving and the slaking of medicament.

The beneficial effects of the utility model are: this efficient PAM intelligence automatic preparing device is by guaranteeing the accuracy of solution concentration to the accurate measurement of PAM dry powder, realized the abundant of PAM solution dissolving by appropriate design stirring intensity, mixing time and streamflow regime, having improved the content of active ingredient in the PAM solution, is a kind of desirable PAM automatic preparing device.

Four, description of drawings

Fig. 1 is elevation of the present utility model.

Fig. 2 is top view of the present utility model.

Five, the specific embodiment

Below in conjunction with accompanying drawing the utility model is further specified.

Among Fig. 1 and Fig. 2, high speed solid-liquid blender 1, dry powder case 2, dissolving box mixer 3, curing box agitator 4, storage bin 5; Dividing plate 6, dissolving case 7.

As shown in the figure, this efficient PAM intelligence automatic preparing device is a square container, and casing is divided into three lattice, is separated by dividing plate, and the casing main body adopts carbon steel lining quality of rubber materials.The dry powder metering throwing device of band heating is fixed on the casing top, and dissolving case and curing box have been installed respectively agitating device, and storage bin is not established agitating device.This device whole height and size can be adjusted according to actual conditions, can not establish cat ladder and platform.The dry powder metering throwing device of band heating is provided with the dry powder hopper, is stainless steel, and the volume of hopper can be adjusted as requested.Whole device is established a centralized-control box, and all electric devices concentrate in the control cabinet and operate, and RCI is arranged, and can realize concentrating PLC control, and control cabinet can be fixed in casing top or be suspended on the casing side.

The liquid process for preparation is, dry powder is put in the dry powder hopper, starts the conveying worm motor and adjusts frequency converter frequency and obtain required dosage, industry water opened adjusted the water yield, starts dissolving case mixer and curing box mixer.Medicinal powder obtains required liquor strength by the electric machine frequency of adjusting inflow and conveying worm in course of dissolution, once can not need to adjust after the debugging well again, only need to start during each run to get final product.

Characteristics of the present utility model are: the dosage of medicinal powder adopts VFC, and the automatic control that both can realize dosage is convenient operation also, and automaticity is higher, can realize remote PLC control and adjustment.The throwing device outlet can prevent that with companion's heat medicinal powder from making moist, and can not cause the obstruction that adds mouth.Current are high speed whirlpool state after entering blender, and medicinal powder can mix with water fast.By casing being divided into the cell with three functions, the medicament active ingredient of having avoided excessive agitation to cause under the prerequisite that guarantees solute effect descends, and the appropriate design of flow-shape also is conducive to the abundant dissolving of medicament.
