Abstract
A horizontal beater with a pressure airtight part at the end of a stirring shaft consists of a horizontal cylinder body and a stirring shaft, wherein, the exterior sides of the two axial end surfaces of the cylinder body is provided with a bearing seat; a hole is arranged in the center of the bearing seat and the hole is provided with a shaft sleeve seat; the shaft end of the stirring shaft passes through the central hole of the shaft sleeve seat and rotatablely bears on the bearing seat; a ring-shaped groove and an installing part for airtight parts are arranged axially in the inner wall of the central hole of the shaft sleeve seat; a gas channel is arranged in the shaft sleeve seat, communicated with the ring-shaped groove and provided with an air inlet; airtight parts are arranged between the installing parts of the airtight parts of the shaft sleeve seat and the shaft surface of the stirring shaft; a gas airtight cavity with 0.5 bar to 1.5 bar pressure is formed between the ring-shaped groove and the shaft surface of the stirring shaft, which ensures that the materials in the cylinder is insulated mutually with the airtight part, thus engendering good airproof effect, protecting the airtight parts of a shaft head and avoiding being abraded by the material seeped in.
Description
Technical field
The utility model relates to a kind of horizontal mixer, and in particular for producing the horizontal mixer of commodity mortars such as dry-mixed mortar, premixing mortar, it has the axle head of stirring pressurized seal portion.
Background technology
Now, commodity mortars such as the dry-mixed mortar that extensive employing batch production is produced in architectural engineering, premixing mortar substitute traditional scene and mix and stir mortar.Commodity mortar have metering accurately, product quality and advantages such as good stability, wide adaptability, serviceability and workability are good, environmental protection, use commodity mortar to improving construction quality and work efficiency, reduction labour intensity and solving environmental problem, play crucial effect.It is raw material that commodity mortar adopts inorganic coagulation material, sand, mineral admixture and additive etc. such as cement usually, also adds some high molecular polymerization fibres and wood-fibreds sometimes, stirs in mixer or stirrer for mixing by a certain percentage and makes.
As the key equipment of producing commodity mortar, the research and development of mixer and application are subjected to the attention of industry always.At present, provide the multiple mixer that commodity mortar is produced that can be used for, comprise vertical or horizontal, twin axle or single axle, continous way or step mixer.Application shows that existing mixer roughly can satisfy the production needs of commodity mortar.But, the existing mixer part that also comes with some shortcomings: for example the sealing of shaft end is not ideal enough, the easy wear out failure of sealing, maintenance maintenance inconvenience, make that being stirred material infiltrates the spindle nose position easily and cause the damage of part portion, has shortened the service life of machine.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, provides a kind of stirring to have the horizontal mixer that stirs axle head pressurized seal portion.
For this reason, the horizontal mixer that the utility model provides with stirring axle head pressurized seal portion, comprise horizontal cylinder and shaft, described cylinder axial end center is offered porose, be provided with sleeve block at described tapping, the axle head of described shaft passes the centre bore of described sleeve block, and it is rotatably mounted, it is characterized in that: the center bore inner wall at described sleeve block is formed with annular groove and the seal installation portion of arranging vertically, in described sleeve block, be formed with gas passage, described gas passage and described annular groove connect, and have an air inlet, between the axial plane of the seal installation portion of described sleeve block and described shaft, be provided with seal.
Best, described seal is the abrasive rubber piece.
Best, between the axial plane of described annular groove and described shaft, form air seal chamber with certain pressure.
Best, gas pressure is 0.5bar～1.5bar in the described air seal chamber.
The horizontal mixer that the utility model provides with stirring axle head pressurized seal portion; has following beneficial effect: between sleeve block and shaft axial plane, have the block rubber seal; and when shaft rotates; by feeding pressure air to gas passage; can between the axial plane of annular groove and shaft, form air seal portion with certain pressure; an interior material and sealing are isolated mutually; form good sealing effectiveness; effectively protection spindle nose obturator is avoided its material that is infiltrated wearing and tearing.
Below, by embodiment the utility model is described in further detail.
Description of drawings
Fig. 1 is the partial schematic diagram with shaft end in the horizontal mixer that stirs axle head pressurized seal portion that the utility model provides.
Fig. 2 is the partial enlarged drawing of A part among Fig. 1.
The specific embodiment
The utility model provides a kind of horizontal mixer that stirs axle head pressurized seal portion that has, and is specially adapted to produce expeditiously the high-quality commodity mortar.Its structure comprises horizontal cylinder 1, shaft 2, is disposed on agitating unit 3 on the shaft 2 etc. vertically.The inside of horizontal cylinder 1 forms and holds the chamber that is stirred material, and the sidewall of cylinder 1 has batch charging mechanism and shedding mechanism (place not shown in the figures), is used for realizing feeding intake, the discharging operation.Each part mentioned above all is known, does not give unnecessary details one by one., only the part relevant with the utility model is described to shown in Figure 2 below with reference to Fig. 1.
In horizontal cylinder 1 axial both ends of the surface arranged outside supporting base 4 is arranged, offer porose at cylinder 1 axial both ends of the surface center, be provided with sleeve block 5 at this tapping, sleeve block has the centre bore of axial perforation, and supporting base 4, sleeve block 5 are fixed on cylinder 1 axial both ends of the surface by bolt 53.Shaft 2 shaft ends are arranged with axle sleeve 21, and this shaft end passes the centre bore of sleeve block 5 and can be rotated to support on the supporting base 4 by bearing 6, and supporting base 4 is by an end cap 41 cappings.Center bore inner wall at sleeve block 5 is formed with annular groove 51 and the seal installation portion of arranging vertically, is formed with gas passage 52 in sleeve block 5, and gas passage 52 is with annular groove 51 perforations and have an air inlet 520.Abrasive rubber piece 7 is installed between axle sleeve 21 axial planes of the seal installation portion of sleeve block 5 and shaft 2, forms sealing.
Its operation principle is: when shaft rotates; can pass through air inlet 520, the dry pressure air of gas passage 52 feedings; thereby between the axial plane of described annular groove 51 and described shaft 2, form the air seal chamber of pressure 0.5bar～1.5bar; this air seal chamber can make an interior material and sealing isolate mutually; effectively protect the spindle nose obturator; avoid its material that is infiltrated wearing and tearing, form good sealing effectiveness.
More than combine embodiment the utility model is illustrated, but this does not constitute restriction of the present utility model, any modification of making under same design, variation and replacement also all belong to the scope of the utility model protection.
