Description
Technical field
The utility model relates to the fluidizer of particle material tank truck, is specifically related to a kind of fluidizer without sideskid.
Background technology
The fluidizer of particle material tank truck utilizes the effect of powder grain material by strength on fluid bed to realize fluidized state, thus carry out discharging.Along with the development of powder grain material transit industry, the demand of closed tank truck and technical requirements are also improving constantly.Application number 200710053844.2 patent discloses a kind of Fluidising device for conveying tank of bulk powdered material, comprise tank body and the fluid bed being arranged on tank base, described fluid bed is arranged on the bottom of tank body along the length direction of tank body, and its width is greater than discharging opening diameter; In the both sides of fluid bed to tank skin line of centers with lower area press close to inner tank wall cambered surface lay bellows flexibility landslide plate, fluid bed and bellows flexibility landslide plate below be respectively arranged with the guide duct be connected with source of the gas; The periphery of described bellows flexibility landslide plate all by connecting element with airtight mode and tank skin concrete mutually; A discharging opening is at least provided with at fluid bed.The bellows flexibility landslide plate being arranged at fluid bed both sides makes air bag heave by the effect of pressure air, not sliding onto the powder grain material pushing tow of fluid bed above fluid bed by gravity, and effectively improves the efficiency of wind energy and accelerates discharge rate.But blemish in an otherwise perfect thing, the fluid bed both sides of this fluidizer are provided with sideskid, occupy the volume of tank body to a certain extent, and too increase the weight of whole fluidizer.In order to meet client's weight-saving demand, must do to optimize further to the structure of existing fluidizer.
Utility model content
Technical problem to be solved in the utility model is the fluidizer providing a kind of particle material tank truck for above-mentioned prior art, under the prerequisite meeting the operatings needs such as vehicle discharging, without the need to separately establishing sideskid in fluid bed both sides, alleviate the overall weight of fluidizer.
The technical scheme in the invention for solving the above technical problem is: a kind of fluidizer of particle material tank truck, comprise tank body and the fluid bed and the air compressor that are arranged on this tank base, the bottom surface of described tank body is in the trend of being sunk in the middle of tank body gradually by tank body two ends, described fluid bed along tank body bottom surface extend and its shape and tank body bottom surface match, it is characterized in that: the tangent line of described fluid bed curved edges and the angle a of horizontal surface are 42 ° ~ 45 °; The area A of described fluid bed meets Amin≤A≤Amax, wherein Amax=Q/ (Ka*Vf) (m
2), Amin=Q/ (60Ka*Vf) (m
2), in formula, Q is the discharge capacity (m of described air compressor
3/ s), Vf is critical fluidized bed air-flow velocity (m/s), and Ka is the air leakage factor of delivery system, gets 1.1 ~ 1.2.
Preferably, described fluid bed is ventilative pocket type.
Particularly, be the situation of cement for the powder grain material in tank body, the volume of described tank body is generally designed to 40m
3, the area A of described fluid bed is 0.23m
2~ 13.8m
2.
Such scheme enters one and is optimized for, and the length of described fluid bed is 8.344m, and wide is 1.25m, and the tangent line of described fluid bed curved edges and the angle a of horizontal surface are 42 °.
Compared with prior art, the utility model has the advantage of: by curved surface radian and the area span of appropriate design fluid bed, under the prerequisite meeting the operatings needs such as vehicle discharging, be such as under the condition of 0.2MPa at operation pressure, the average discharge rate of fluid bed is not less than 1.2t/min, surplus ratio is not more than the serviceability requirement of 0.3%, eliminates and separately establishes sideskid in fluid bed both sides, thus reaches the object simplifying fluidizer, alleviate fluidizer overall weight.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of fluidizer length direction in the utility model embodiment;
Fig. 2 is the sectional view of fluidizer tank body.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
As illustrated in fig. 1 and 2, the fluidizer of the particle material tank truck in the present embodiment, comprise tank body 1 and the fluid bed 2 be arranged on bottom this tank body 1 and air compressor (not shown in FIG.), the bottom surface of described tank body 1 is in the trend of being sunk in the middle of tank body 1 gradually by tank body 1 two ends, described fluid bed 2 along tank body 1 bottom surface extend and its shape and tank body bottom surface match, the tangent line of described fluid bed curved edges and the angle a of horizontal surface are 42 ° ~ 45 °; Area A=fluid bed width D * fluid bed length L (L=L1+L2) of described fluid bed, and meet Amin≤A≤Amax, wherein Amax=Q/ (Ka*Vf) (m
2), Amin=Q/ (60Ka*Vf) (m
2), in formula, Q is the discharge capacity (m of described air compressor
3/ s), Vf is critical fluidized bed air-flow velocity (m/s), and Ka is the air leakage factor of delivery system, gets 1.1 ~ 1.2.
From above formula, when Q mono-timing, A and Vf is inversely proportional to, if the area of fluid bed is excessive, the air-flow velocity through fluid bed will be less than the critical fluidization velocity of powder, the fluidization that powder just can not be good, and poor fluidity, is easily trapped on fluid bed bed surface; If fluidized bed area is too small, the air-flow velocity through fluid bed will be greater than the Minimum Fluidization Velocity of White of powder, forms dilute phase fludization bed, makes the stable operation behavior of bed sharply depart from normal behaviour, and cause operation not normal, discharging is incomplete.
The present embodiment is the situation of cement for powder, and the effective volume of design tank body 1 is 40m
3, tank body 1 join air compressor discharge capacity Q be 9m
3/ min, Vf=0.009m/s, the air leakage factor Ka of delivery system gets 1.2, then Amax=13.8m
2; Amin=0.23m
2.Fluid bed 2 adopts ventilative pocket type, and design 10 venting bags in tank body 1, the design size of venting bags is wide 125mm, long 8344mm, and a is 42 °, designed fluidized bed area A=10 × 0.125 × 8.344=10.43m
2, be less than maximum empty bed surface and amass 13.8m
2, be greater than minimum empty bed sectional area 0.23m
2, so design of Fluidized bed is rational, discharging requirement can be met without the need to additional sliding plate in tank body.
