Abstract
The utility model relates to an anti-blocking airproof device, comprising a machine shell. The upper end of the machine shell is provided with a feeding inlet, while the lower end has a feeding outlet. The machine shell inside is provided with a revolving shaft, and the revolving shaft is provided with an impeller. The impeller has a lamina. The lamina in the impeller is radial to be a ''V-shaped'' structure. The utility model is simple in structure, excellent in anti-blcoking and airproof performance, and is applicable for anti-block airproof, is applicable to successive discharging of materials in the different shape and with different grain diameter.
Description
(1) technical field: the utility model belongs to the corollary equipment in strength conveying and the dust ventilating net, particularly a kind of anti-blocking air sealer.
(2) background technology: air sealer mainly is with material separated in discharger or the dust exhaustor or dust continuously in time in the exhaust to atmosphere pipeline, stop simultaneously in the air admission discharger or dust exhaustor in the atmosphere duct, because air sealer mainly has been discharge and close gas effect, be the anti-blocking performance and the airtight performance of air sealer so estimate the major criterion of the quality of air sealer.In recent years, along with developing rapidly of strength conveying and dedusting technology, the performance of air sealer is being updated, and its anti-blocking performance and airtight performance all have certain improvement, but the blade of the impeller of existing various air sealers is straight-plate-type, so all exist such or such problem.
As shown in Figure 1, in order to reach the requirement of close gas, the gap between blade and the casing is all very little, if in the material of discharging sheet, fibrous material are arranged; Then sheet, fibrous material are stuck between the blade and casing of rotary airlock easily, produce friction between blade and the casing, and resistance increases greatly, causes impeller to be stuck, and can not rotate, even burn out motor.Often have some sheets or fiberous material in addition between blade and the casing, friction aggravation between blade and the casing, casing inner wall weares and teares easily, makes the gap increase between blade and the casing inner wall, influences the close gas of air sealer, shortens the service life of air sealer.
As shown in Figure 2, the air sealer that has staggers the inlet point and the discharge gate of air sealer, utilizes the material in the air sealer to come close gas effect, but the material that air sealer row unloads can not be full of the effective volume of air sealer, and close gas is also undesirable.
As shown in Figure 3, the air sealer that has leaks out and the problem that is stuck of impeller in order to solve, and does the gap between blade and the casing bigger, at the end of blade dress lastblock rubber, rubber is contacted with casing inner wall then, can reach the requirement of close gas.Simultaneously, if there is material to be stuck between blade and the casing, then rubber bumper produces elastic deformation under the effect of squeese pressure and friction force, thereby solves the problem that impeller is stuck.But owing to remaining with casing, rubber contacts, and the thickness that rubber bumper need be certain, therefore,, there is bigger friction force between rubber and the casing inner wall all the time no matter whether there is material to be stuck between blade and the casing.Be overcome friction, just must increase the power of motor, power consumption is increased greatly.Facts have proved that air sealer shown in Figure 3 is in all successes of industries such as chemical industry, metallurgy, timber, but small profit trades such as grain and oil, feed are just not too practical, in addition, rubber is the product that is made of the chemical substance composition, contains harmful composition.
Shown in Figure 4, in order to solve the problem that air sealer leaks out and impeller is stuck, in conjunction with grain, oil, the actual conditions of industries such as feed processing, on Fig. 3 basis, improve, spring is loaded onto in the end of impeller, portable plate, when material is stuck between portable plate and the casing inner wall, then under the effect of squeese pressure, length of spring compressed, the gap increase between blade and the casing, the size in gap, big facet automatically regulating because of extruding, squeese pressure disappears after the material that is snapped into is discharged to discharge port, and portable plate recovers and the very little gap of casing state of contact under the effect of spring force.But when this kind air sealer unloads sheet, fiberous material row, material is stuck in the side plate groove of portable plate and impeller, cause the blade upper mobile board not automatically reset, at this moment be easy to cause close gas weak effect, leak out, it is very big to the casing abrasion to be stuck in top material, influence service life of equipment, and its process of manufacture complex procedures, keep in repair bigger than other Blowing stopper difficulty.
The purpose of this utility model overcomes the problems referred to above exactly, provides a kind of simple in structure, anti-blocking, airtight performance is good, is applicable to the anti-blocking air sealer that the continuous row of difformity, different-grain diameter material unloads.
(3) summary of the invention: the anti-blocking air sealer of the utility model, it has a casing, and the casing upper end is an inlet point, the lower end is a discharging opening, and rotating shaft is housed in the casing, establishes impeller in the rotating shaft, impeller is provided with blade, and the blade on the impeller becomes " V " type structure in radially projecting.
The utility model is simple in structure, and is anti-blocking, airtight performance is better, is applicable to that the continuous row of difformity, different-grain diameter material unloads.
Anti-blocking air sealer principle of work
The utility model is made both sides with the blade of impeller and is formed " V " shape toward intermediate, inclined, rotate by the recessed direction of the blade on the hour wheel during air sealer running, make blade and impeller radius keep a certain angle like this, when material snaps between blade and the casing, because of squeese pressure is a radial direction along impeller, and blade and impeller radius are at an angle, so blade can be decomposed into squeese pressure and tangential force to the application force that is snapped into material, this tangential force is opposite with the action direction of friction force.Thereby friction force is reduced, and also alleviate the load of air sealer, make it normal running work continuously, prolonged air sealer service life.

(5) concrete enforcement
Referring to Fig. 5, Fig. 6 and Fig. 7, make casing 1 with metallic material, again the blade on the impeller 45 is formed in one-tenth " V " type structure in the radially projecting.The casing upper end is an inlet point 2, and the lower end is a discharging opening 3, and rotating shaft 6 is housed in the casing, establishes impeller in the rotating shaft, is equipped with blade on the impeller.
