Abstract
The invention provides a swivel head cover of an electric centrifuge. According to the electric centrifuge frequently used in the laboratory presently, the swivel head cover flies out if the swivel head cover is not screwed tight, and accidents can be caused. The swivel head and the swivel head cover of the existing electric centrifuge are generally connected through threads and have the defect of being poor in sealing effect. The swivel head cover of the electric centrifuge comprises a swivel head cover body (1) connected with a swivel head cover flange (2), the swivel head cover flange is matched with a swivel head flange, and an annular protrusion (4) is arranged on the swivel head cover flange, located on the attachment surface of the swivel head cover flange and the swivel head flange and matched with an annular groove (5) arranged on the swivel head flange. The swivel head cover is applied to ancillary facilities of the electric centrifuge.
Description
Technical field
The present invention relates to a kind of chemical engineering experiment apparatus, be specifically related to a kind of rotary head lid of use for laboratory electric centrifuge.
Background technology
Centrifuge is to utilize centrifugal force, the machinery of each component in the mixture of separating liquid and solid particle or liquid and liquid.Centrifuge is mainly used in the solid particle in the suspension and liquid are separated; Or with two kinds of density differences in the emulsion, immiscible liquid separates (for example isolating cream from milk) again; It also can be used for getting rid of the liquid in the wet solid, for example dries wet clothes with washing machine; Special hypervelocity channel separator is the admixture of gas of separable different densities also; Utilize the different characteristics of solid particle sinking speed in liquid of different densities or granularity, the sedimentation centrifuge that has also can carry out classification by density or granularity to solid particle.Centrifuge is widely used in the departments such as chemical industry, oil, food, pharmacy, ore dressing, coal, water treatment and boats and ships.
At present, what the laboratory was commonly used is electric centrifuge, and the electric centrifuge velocity of rotation is fast, if use procedure is not noted having very large potential safety hazard, in case if particularly the rotary head of electric centrifuge lid is not tightened error starting, the rotary head lid will fly out, and causes the accident.The general employing is threaded between the rotary head of existing electric centrifuge and the rotary head lid, if screw thread not have tight cooperate or thread abrasion also is prone to accidents in the excessive situation elder generation of rotating speed in the process of tightening.And being threaded exists the bad defective of sealing effectiveness, and needing increases independent sealing gasket, but often uses the stronger solution of some corrosivity in the chemical engineering experiment, causes easily the corrosion of sealing gasket, causes that solvent leaks.
Summary of the invention
The objective of the invention is provides a kind of electric centrifuge rotary head lid for the problem of above-mentioned existence, is connected firmly the security incident of avoiding electric centrifuge use procedure transfer skull to come off and cause, and good sealing effect.
Above-mentioned purpose is achieved through the following technical solutions:
Electric centrifuge rotary head lid, comprise rotary head lid body, described rotary head lid body connects rotary head lid flange, described rotary head lid flange cooperates with the rotary head flange, have an annular protrusion on the described rotary head lid flange, described annular protrusion is positioned at the surface of described rotary head flange applying and with an annular groove on the rotary head flange and matches.
Described electric centrifuge rotary head lid, described rotary head lid flange carries out clamping hoop type with described rotary head flange by holding firmware and is connected.
Described electric centrifuge rotary head lid, have respectively mutual corresponding fastener hole on described rotary head lid flange and the described rotary head flange, described rotary head is covered between flange and the described rotary head flange and is connected by the fastening bolt that is installed in the described fastener hole.
Beneficial effect:
1. the present invention adopts flange to connect, connection safety is high, the security incident that has produced when having avoided being threaded closely, simultaneously the present invention has cancelled gasket seal, form hard sealing between the projection that employing cooperatively interacts and the groove, avoided pad easily stuck or be bonded in the inconvenience that brings on the sealing surface, can greatly make things convenient for and install and overhaul, irreplaceable meaning has particularly more been arranged in the application of high temperature high pressure device.
2. the present invention is simple in structure, and is easily manufactured, is convenient to centering and installs; Owing to do not need in addition processing and dismounting pad, can reduce processing charges, greatly reduce installation and repairing difficulty and workload, and avoided causing because of the dismounting pad cut of sealing surface, greatly raise labour efficiency; The sealing surface axial displacement redeeming that causes is internally pressed in the axial elasticity distortion that particularly produces under the internal pressure effect with the cannelure of arc surface, realizes self-tightening sealing; The crooked deformability that has with the cannelure of arc surface is strong more than the deformability that the screen resilience of pad produces, and has greatly improved the reliability of sealing.
