Description
Technical field
The present invention relates to a kind of severe corrosive solution hold-up vessel liquid level detection device, be used to detect the liquid level that stores pot liquid, belong to the automatic detection range of hold-up vessel liquid level.
Background technology
In industrial processes, the liquid level of many strongly corrosion liquid hold-up vessels needs online detection.For example liquid such as the concentrated sulphuric acid, concentrated hydrochloric acid, SPA, red fuming nitric acid (RFNA), strong aqua, nickel sulfate solution, chromium sulfate solution all have very strong corrosivity, are easy to corrode level meter, and therefore automatic detection is a difficult problem always to the liquid level of strongly corrosion liquid hold-up vessel.Owing to have severe corrosive, the general non-contact detection method that adopts in industrial process.The liquid level that adopts radar levelmeter to detect the strongly corrosion liquid hold-up vessel is one of method of using always; Because strongly corrosion liquid forms thick fog easily in the production run in hold-up vessel; Even in radar levelmeter detecting head surface dewfall; Perhaps stick on the radar levelmeter, radar levelmeter is caused corrosion.Radar levelmeter costs an arm and a leg in addition, and for the occasion with a plurality of hold-up vessels, it is higher to use the input expense.Ultrasonic material level meter belongs to the non-contact detection instrument, has characteristics such as price is lower, accuracy of detection height, but can not be applicable to the Level Detection of the strongly corrosion liquid hold-up vessel with thick fog and easy dewfall.Because there is the deficiency of measurement range less (less than 10 meters) in ultrasonic material level meter, can't directly be used for the detection of higher hold-up vessel liquid level.
Summary of the invention
The present invention provides a kind of ability automatic on-line to detect the pick-up unit of strongly corrosion liquid hold-up vessel liquid level in order to overcome the deficiency that exists in the above-mentioned prior art.
This pick-up unit comprises float, pulley, fixed pulley support, connection cord, reflecting plate, ultrasonic material level meter; Its middle pulley is installed on the fixed pulley support; Form fixed pulley, the fixed pulley support is installed on the hold-up vessel, and float is connected on the reflecting plate through connection cord and pulley; Float floats on the storage tank level; The weight of float should be greater than 1.5 times of the general assembly (TW) of connected movable member, ultrasonic material level meter be installed in reflecting plate under, its setting height(from bottom) is the position of float reflecting plate when arriving the extreme higher position.
Float has the wire rope handling via hole among the present invention, and connection cord ties up on the via hole.
Float adopts and to have the strong PTFE material of corrosion resistance and process among the present invention, owing to consider the dirigibility of device action, the weight of float should be greater than 1.5 times of the general assembly (TW) of connected movable member.

Among the present invention when in the range of concentrated sulphuric acid hold-up vessel height at ultrasonic material level meter; Device does not adopt travelling block between connecting; Float is connected to reflecting plate through connection cord, two fixed pulleys; The stroke of reflecting plate equals the stroke of float, the measured value of the height-ultrasonic material level meter of the liquid level=hold-up vessel of strongly corrosion liquid hold-up vessel.
Among the present invention when concentrated sulphuric acid hold-up vessel height is in the range of 1 to 2 times of ultrasonic material level meter; Float (1) is connected on the fixed pulley support in the hold-up vessel outside through connection cord, two fixed pulleys and a travelling block; Reflecting plate is connected the below of travelling block, and the stroke of reflecting plate is 1/2nd of a float distance of run.
Among the present invention when concentrated sulphuric acid hold-up vessel height is in the range of 2 to 4 times of ultrasonic material level meters; Float is connected on the fixed pulley support in the hold-up vessel outside through connection cord, three fixed pulleys and two travelling block; The axle of two travelling block is installed on the running block pedestal; Reflecting plate is connected in the centre of running block pedestal, and the stroke of reflecting plate is 1/4th of a float distance of run.
Among the present invention when concentrated sulphuric acid hold-up vessel height is in the range of 4 to 6 times of ultrasonic material level meters; Float is connected on the fixed pulley support in the hold-up vessel outside through connection cord, four fixed pulleys and three travelling block; The axle of three travelling block is installed on the running block pedestal; Reflecting plate is connected in the centre of running block pedestal, and the stroke of reflecting plate is the sixth of float distance of run.
When device has travelling block, the number of the measured value * travelling block of the height-ultrasonic material level meter of the liquid level=hold-up vessel of strongly corrosion liquid hold-up vessel * 2.
This device is through float and corresponding linkage part; The liquid level that hold-up vessel is inner reflects liquid level change in the hold-up vessel through the displacement of the outer ultrasonic material level meter detection of reflected plate of jar; And go out to store the liquid level of pot liquid according to the distance calculation that measures; Realized that interior liquid surveys outward, thereby avoided the corrosion of strongly corrosion liquid measurement instrument, and the adverse effects to detecting such as acid mist, dewfall.
This device only passes through to increase the travelling block quantity of device in the measurement range of limited ultrasonic material level meter, can be so that the multiplication of the liquid level scope of actual measurement concentrated sulphuric acid hold-up vessel.
The present invention is the detection that is applicable to liquid level in the strongly corrosion liquid hold-up vessel with respect to the beneficial effect of prior art; And be applicable to the Level Detection of the hold-up vessel of super large height; This apparatus structure is simple; Easy to operate, can realize the real time automatic detection of liquid level in the strongly corrosion liquid hold-up vessel.Externally measured owing to pot liquid is guided to, less demanding to the anti-corrosive properties of ultrasonic level meter.In addition; Ultrasonic material level meter or its range of radar levelmeter commonly used are all more limited; The level meter of employing super large range then price is very expensive, for the excessive situation of hold-up vessel height, adopts the present invention can realize surveying (liquid level) greatly with little (range); Reduced investment but also applied widely not only also is applicable to the Level Detection of other kind containers or the unsettled liquid of density.
