Description
Technical field
The utility model belongs to Wood-based Panel Production material transport equipment technical field, relates to the sealing arrangement of conveyor screw, relates in particular to the thread sealing device that a kind of wood-based plate is used conveyor screw.
Background technology
Conveyor screw is commonly called as auger, it is the wider a kind of load transfer device of purposes in mineral products, feed, grain and oil, the building industry, angular divisions according to the convey materials sense of displacement, conveyor screw is divided into horizontal conveyor screw and vertical screw conveyor two large types, is mainly used in horizontal feed and vertical-lift to bulk materials such as various powderies, graininess and fritter shapes.Conveyor screw is made by steel, for delivery of chemical industry, building materials products such as the higher powder of temperature or particulate matters.Conveyor screw generally is comprised of conveyer body, feed inlet and outlet and actuating device three parts, in the conveyer body interior screw shaft is arranged, and the blade curl is welded on the screw shaft.Contact-type seal is adopted in the sealing at the enclosure interface place of screw shaft and conveyer body more, namely adopts soft filler, such as materials such as felt, rubber, asbestos, is filled in the interface position, leaks out from interface to prevent convey materials.Chinese patent CN201980720U is provided with gland packing at the conveyor screw interface exactly, and this filler employing is asbestos packing.
The normal conveyor screw that uses transports the wood chip material in the beaver board production process, because the body seal of screw shaft and conveyer body adopts contact-type seal, after when equipment moves one section, often there is part wood chip in small, broken bits to spill from sealing, cause the environmental pollution of production scene, bring certain potential safety hazard, simultaneously the normal operation of other equipment of production scene also had potential impact.Run into seal leakage, need often to adjust or change filler, thereby equipment easy to wear increases power consumption.Non-contacting seal is to reach sealing effectiveness by produce pressure drop in sealed fluid, and does not affect rotatablely moving of movement parts.In non-contacting seal, there is not the friction between sealing and the movement parts, therefore not wearing and tearing, such sealing has the characteristics such as project organization is simple, durable, reliable, almost can maintain.What conveyor screw transported in the beaver board production is the solid materials more in small, broken bits such as wood chip material, can utilize non-contacting seal to achieve the goal.Same principle is transported similar particulate matter, finely divided material etc. in every case in association area, can both utilize the mode of non-contacting seal to come conveyor screw is carried out encapsulation process.
Summary of the invention
The utility model is to have proposed new hermetically-sealed construction for the body seal effect of the screw shaft that solves conveyor screw and conveyer body is bad.
The wood-based plate thread sealing device of conveyor screw, the shell (1), screw shaft (2) and the screw collar (3) that comprise the conveyor screw body, described screw shaft (2) passes shell (1), and described screw collar (3) is fixed on the surface of screw shaft (2) and is connected with shell (1).
Described screw collar (3) can directly be welded on the screw shaft (2), also can utilize binding bolt to captive joint with screw shaft (2), and perhaps other common fastening means connect.
In preferred embodiment of the utility model, the wood-based plate thread sealing device of conveyor screw, the hand of rotation the when hand of spiral on described screw collar (3) surface is worked with screw shaft (2) is opposite.
In preferred embodiment of the utility model, the wood-based plate thread sealing device of conveyor screw, the screw thread on described screw collar (3) surface is 2 ~ 4 square threads.
In preferred embodiment of the utility model, the wood-based plate thread sealing device of conveyor screw, the screw thread on described screw collar (3) surface is 2 ~ 4 head saw profile of tooth screw threads.
The radial runout value that the threaded top on described screw collar (3) surface and the distance between the shell (1) are screw shaft (2)+0.1 ~ 0.2mm.
Beneficial effect
Owing to adopt contactless thread seal, at solid materials more in small, broken bits such as artificial board product line transportation wood chip materials, need not to adjust maintenance after the installation, avoided contact-type seal need to change the trouble in gland packing or the equipment of adjustment gap, improved work efficiency, guarantee carrying out in order of production, played the effect of falling preferably this section consumption.
Description of drawings
Accompanying drawing is the thread sealing device scheme drawing that wood-based plate is used conveyor screw.
Wherein each parts is respectively: 1 is the shell of conveyor screw body, and 2 is screw shaft, and 3 is screw collar.
