Description
Technical field
The present invention relates to a kind of single screw rod central pressing obturator, relate in particular to a kind of three products cyclone list screw rod central pressing obturator that heavily is situated between.
Background technology
The nucleus equipment of dense-medium separation system is the three products cyclones that heavily are situated between, and selected feed coal obtains cleaned coal, middle coal, three kinds of products of tail coal after one section, the two sections sortings of cyclone that heavily are situated between.Middle coal and spoil enter two sections cyclones after one section cyclone sorting.The pan feeding of two sections cyclones less than 80*80 mm, often has the foreign material such as super granularity, irregular bulk materials, ironware, cotton yarn to enter system by granularity requirements in the pan feeding in the production process, often cause two sections feeding mouths of cyclone to stop up.When carrying out accident treatment, usually adopt two sections cyclones of dismounting to come the processing accident by the two sections accident treatment holes that bolt forms that penetrate of four M20, have following problem in this device use procedure: (1) four bolts adopts the mode that penetrates half opening to be fixed sealing, dismantles and the installation duration.(2) in the fastening bolt process, carry out fasteningly because taking open type to penetrate bolt, construction bolt is wanted symmetry progressively to pressurize to tighten, be prone to the poor phenomenon of the fixed degree of balance; Simultaneously, sealing device adopts common asbestos pad, simplicity of design, and unloading process very easily damages; Therefore, under internal pressure, easily cause local the leakage, reliability is low.Only heavily could find behind the unlatching of Jie system and the band material when (3) leaking material, unreliable because of the poor and seal of the degree of balance, when carrying out the inspection processing of leakage problem, use duration, process is loaded down with trivial details, can cause like this and must repeatedly open the system that heavily is situated between, the test fastening treatment effect of device, have a strong impact on the operational efficiency of three-product cyclone, very easily caused the untimely product cross pollution of troubleshooting, affected separating effect.
Summary of the invention
The purpose of this invention is to provide a kind of three products cyclone list screw rod central pressing obturator that heavily is situated between, dismounting is simple, can keep stability, and the degree of balance is better.
For achieving the above object, the technical solution used in the present invention is:
A kind of three products cyclone list screw rod central pressing obturator that heavily is situated between, comprise below locating piece and base, it is characterized in that: support bar is installed in the both sides of base, the top locating piece is installed by alignment pin in the two ends of support bar, the below locating piece is provided with setscrew nut, the positioning screw one end setscrew nut that is spirally connected, the other end of positioning screw pass top locating piece, the other end mounting handle of positioning screw.
According to the described three products cyclone list screw rod central pressing obturator that heavily is situated between, it is characterized in that: described below locating piece is pressed on the base, positioning screw and top locating piece bolt.
Advantageous effect of the present invention is: it is comprised of base, below positioning pressuring plate, gripper shoe, top locating piece, alignment pin, positioning screw and setscrew nut, handle.4 gripper shoes are welded and fixed on the plant bottom case, are connected with the top locating piece by alignment pin, have positioning screw hole in the middle of the locating piece of top.Setscrew nut is welded on the centre position of below positioning pressuring plate, positioning screw aligns by the screw of top locating piece and setscrew nut on the positioning pressuring plate of below and cooperates, by the rotatable handle screw rod, the below positioning pressuring plate is carried out fastening or removes, with the rapid opening and closing in realization accident hole.This device is opening fast and fast compressing device of a kind of accident hole, and it has enhances productivity, reasonable in design, and positioning accuracy is high, the characteristics such as low cost of manufacture.

The specific embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments:
The present invention as shown in Figure 1, a kind of three products cyclone list screw rod central pressing obturator that heavily is situated between, comprise below locating piece 4 and base 1, it is characterized in that: support bar 2 is installed in the both sides of base 1, top locating pieces 6 are installed by alignment pin 3 in the two ends of support bar 2, and below locating piece 4 is provided with setscrew nut 5, the positioning screw 7 one ends setscrew nut 5 that is spirally connected, the other end of positioning screw 7 passes top locating piece 6, the other end mounting handle 8 of positioning screw 7.According to the described three products cyclone list screw rod central pressing obturator that heavily is situated between, it is characterized in that: described below locating piece 4 is pressed on the base 1, positioning screw 7 and top locating piece 6 bolts.
Use principle of the present invention is as shown in Figure 1, 2: this device is comprised of positioning base and movable compacting part, it is characterized in that described positioning base comprises the base 1 on the equipment of being welded on, be welded on four support bars 2 on the base 1, below locating piece 4 and alignment pin 3,5, four support bars of setscrew nut 2 that are installed on the locating piece 4 of below are firm with base 1 vertical welding; Described compacting part has top locating piece 6, positioning screw 7, handle 8, and handle 8 is sleeved on the positioning screw 7, and the setscrew nut 5 on positioning screw 7 and the below locating piece 4 aligns cooperation.Its operation principle is: at first four support bars 2 are welded and fixed on the plant bottom case 1, are connected with top locating piece 6 by alignment pin 3, have positioning screw hole in the middle of the top locating piece 6.Setscrew nut 5 is welded on the centre position of below locating piece 4, positioning screw 7 aligns by the screw of top locating piece 6 and setscrew nut 5 on the below locating piece 4 and cooperates, by handle 8 rotation positioning screws 7, below locating piece 4 is carried out fastening or removes, with the rapid opening and closing in realization accident hole.Below locating piece 4 adopts the dovetail groove rubber gasket to seal with equipment sealing place, and sealing effectiveness is good, has guaranteed the normal operation of system.
