Abstract

The utility model relates to a mixer for sewage treatment. At present, the mixer in use has the defects of limited depth in the water, non-suitableness for deep-water operations and small service area. The utility model includes a base, a motor, a pipe spreader on the lower end of the base, a propeller and a transmission shaft arranged in the inner cavity of the pipe spreader. The lower end of the pipe spreader is provided with a pump case and a guide distributor with a water outlet. The utility model is characterized in that a guide cylinder is arranged between the pump case and the guide distributor; the upper end of the guide cylinder is connected with the shell case and the lower end is connected with the guide distributor. The mixer with such a structure is applicable to deep-water operation. The utility model with large service area also improves the mixing efficiency.

Description

Vertical circulation mixer

The utility model relates to a kind of mixer that is used for sewage disposal.

Mixer plays and stirs active mud in the biochemical treatment process of sewage, and microorganism is fully contacted with matrix, improves the effect of treatment effect.The patent No. of our invention a kind of stirring pump that has been 98224697.8 patent disclosure, it mainly by support, be positioned at motor on the support, be located at propeller, pump case, the directed dispenser that is connected with pump case under the support and place the power transmission shaft of pump case to form, this patent structure is simple, stir, stirring capacity is big.But this patent remains two problems, the one, the degree of depth that directed dispenser inserts in the water is limited, its to around current of diffusion be subjected to big resistance, the difficult mud that stirs at the bottom of the high pond of the degree of depth, generally can only be applicable to 5 meters with interior depth of water scope, be not suitable for deepwater work.The 2nd, the distance between pump case water inlet and the directed dispenser delivery port is little, short through the ring-type main flow band that directed dispenser forms after diffusion all around, circulation power is little, and flow velocity is slower, the circulation area of the ambient water that ring-type main flow band can drive is little, has influenced service area.Though can improve directed dispenser and stretch into the degree of depth in the water by increasing power transmission shaft, can bring that bearing is easy to wear, machine life short, increase the shortcoming of making difficulty of processing etc. but increase axial length, and can't overcome between pump case water inlet and the directed dispenser delivery port apart from the little defective of the little service area that brings.

The purpose of this utility model is to overcome the defective of prior art, and a kind of vertical circulation mixer that can adapt to 5 meters with headwater depth operation, raising service area is provided.

The technical solution of the utility model is: vertical circulation mixer, comprise the support that places on the floating drum, the motor that is connected the support upper end and the pipe spreader of support lower end, the pipe spreader inner chamber has a power transmission shaft, power transmission shaft one end is connected with motor shaft, the other end links to each other with propeller, the pipe spreader lower end is provided with pump case, have water inlet on the pump case, its lower end is provided with the directed dispenser of taking the mouth of a river out of, it is characterized in that being provided with between pump case and the directed dispenser guide shell, the upper end of guide shell is connected with pump case, and the lower end is connected with directed dispenser.Setting up guide shell helps directed dispenser to stretch into the degree of depth in the water, be convenient to deepwater work, easily stir the mud at the bottom of riverbed or the pond, increased the distance between pump case water inlet and the directed dispenser delivery port simultaneously, circulation main flow band is increased, impel the water in river embankment or the cesspool to form the systemic circulation of stirring up and down, realized that large-area three-dimensional circulation stirs.

Described three-dimensional circulation mixer, guide shell is made up of with upper shell two joints, can select the hop count of guide shell according to the pond of reality deeply, can make mixer adapt to the cesspool of different depth like this.

Described three-dimensional circulation mixer, pipe spreader and pump case are provided with a trash rack outward, trash rack in the form of a ring, the upper end is connected with support, the lower end is connected with pump case, the effect of trash rack is to isolate foreign material such as big plastic sheeting, weeds to enter in the pump case, to prevent the stifled or winding screw slurry of card, influences complete machine and normally moves.

Described three-dimensional circulation mixer, directed dispenser is provided with the delivery port that is circle distribution more than 4, is beneficial to current direction and evenly sprays diffusion all around.

The utility model is compared with prior art, is skillfully constructed, and is easily manufactured, especially sets up guide shell and brings following advantage: (1) makes and stirs the function deepwater work, can adapt to 5 meters cesspools with headwater depth and handle.(2) realized that the three-dimensional circulation of large tracts of land stirs, riverbed or pool bottom sludge have been in all the time stir and suspended state, reduced the stirring dead angle, enlarged service area, improved stirring efficiency.

Below in conjunction with drawings and Examples the utility model is further described.

Fig. 1 is a structural representation of the present utility model.

As shown in Figure 1, the utility model is by placing the support 2 on the floating drum 4, the motor 1 that is connected support 2 upper ends, pipe spreader 5, power transmission shaft 6, trash rack 7, pump case 8, propeller 10, guide shell 11, directed dispenser 12 to form, one end of pipe spreader 5 is connected with support 2, and the other end is connected with the upper end of pump case 8.Power transmission shaft 6 one ends that are positioned at pipe spreader 5 are connected with motor shaft by shaft coupling 3, and the other end propeller 10 interior with placing pump case 8 links to each other.Cooperates fixingly between power transmission shaft 6 and the shaft sleeve 5 by the bearing of device at the axle two ends, bottom end bearing must guarantee good sealing, can not make in the water infiltration pipe spreader.Pipe spreader and pump case are provided with a trash rack 7 outward, trash rack in the form of a ring, the upper end is connected with support, the lower end is connected with the lower end of pump case.Have water inlet 9 on the pump case 8, its lower end is provided with directed dispenser 12, is provided with a guide shell 11 between pump case and the directed dispenser, and guide shell 11 is made up of two joint cylindrical shells, and directed dispenser 12 is provided with 6 delivery ports that are circle distribution.Have centre bore on the floating drum 4, be provided with bolt around the hole, after whole host groups is dressed up one, pass the floating drum centre bore, supported and installed on the floating drum by support 2, both are integral with bolting.

The utility model is mainly used in the processing engineering of various sewage, during use, complete machine directly is positioned on the water surface, and guide shell is vertically goed deep in the water.During operation, by the rotation of driven by motor power transmission shaft and propeller, propeller produces strong current and is delivered to directed dispenser through guide shell sprays diffusion in the deep water below 5 meters, can form several ring-type main flow bands, and the mud at the bottom of the picking-up pond upwards stirs.Simultaneously, because ring-type main flow strip length increases, flow velocity is bigger, can form on every side with the main flow band is the regions of turbulent flow at center, impels sewage to form the systemic circulation of stirring up and down, has realized that large-area three-dimensional circulation stirs.
