Abstract
The invention discloses an automatic water level control device of a vacuum sizing tank, and belongs to the technical field of vacuum sizing tanks. The automatic water level control device comprises a tank body (1), a spray pipe (2), a circulation water pump and a water supply tank (5). The automatic water level control device is characterized in that a water level sensing cup (9) is arranged beside the tank body (1), the bottom of the water level sensing cup (9) is communicated with circulation spraying water in the tank body (1) via a communication pipe (8), an upper water level limitation sensor (11) and a lower water level limitation sensor (10) are arranged in the water level sensing cup (9), the upper water level limitation sensor (11) is connected with a drainage electromagnetic valve (6) via a controller (13), and the lower water level limitation sensor (10) is connected with a water inlet electromagnetic valve (4) via the controller (13). The automatic water level control device can automatically supply the water and discharge the water, so that the liquid level in the tank body can be kept, the control precision can be improved, and the fault rate of the liquid level sensor is reduced.
Description
Technical field
The invention belongs to the vacuum sizing box technical field, be specifically related to a kind of water-level control apparatus of vacuum sizing box.
Background technology
Plastic pipe in process of production, the pipe fitting of extruding through extruder has higher temperature, and indefinite form.Way commonly used is, pipe fitting process vacuum sizing box with extruding utilizes the negative pressure swabbing action in sizing tank, the pipe fitting that still is in soft state is radially extended out form circle, utilize simultaneously the cooling water in casing to carry out spraying cooling, thereby reach the effect of hole enlargement typing.Existing vacuum sizing box is generally after pipe fitting enters the vacuum sizing box cooling section, and self circulation line of water conservancy in casing carries out circulated sprinkling to pipe fitting cooling, the cooling and shaping effect of realization to pipe fitting.But in production practices, find when in the casing of cooling water at vacuum sizing box during circulated sprinkling, owing to can making cooling water temperature constantly increase after cooling water and pipe fitting heat exchange, and the water level in casing is unstable during cooling water circulation, make the vacuum in casing also unstable, thereby have influence on the quality of pipe fitting.For solving this technical problem, available technology adopting is installed liquid level sensor in the casing of vacuum sizing box, controls corresponding magnetic valve and opens and closes, and makes to keep stable liquid level in vacuum chamber.But because liquid level sensor is immersed in water often, and the temperature in casing is higher, causes level sensor fault rate height and easily damages, and often causes the out of control of system.
Summary of the invention
For the prior art above shortcomings, the purpose of this invention is to provide and a kind ofly can realize automatic feeding water and draining, make the liquid level in casing keep stable, can improve control accuracy again, reduce the vacuum sizing box water-level control apparatus of level sensor fault rate.
for achieving the above object, the present invention is achieved through the following technical solutions: a kind of water level automatic control device of vacuum sizing box, comprise casing, shower, water circulating pump and water supply tank, be provided with a water level induction cup by described casing, described water level induction cup bottom was communicated with circulated sprinkling water in casing by communicating pipe, be provided with water level upper limit inductor and water level lower limit inductor in the water level induction cup, water level upper limit inductor is connected with drain solenoid valve by controller, described drain solenoid valve is arranged on the drainpipe of casing, water level lower limit inductor is connected with entering water electromagnetic valve by controller, described entering water electromagnetic valve is arranged on the water inlet pipe of casing and is connected with water supply tank, described water level induction cup top is connected by the position that vacuumizes in vacuum tube and casing.
The circulated sprinkling water level upper limit height that will control in the nozzle position of water level upper limit inductor of the present invention and casing is consistent.
The circulated sprinkling water level lower limit height that will control in the nozzle position of water level lower limit inductor of the present invention and casing is consistent.
compared with prior art, beneficial effect of the present invention has: owing to being provided with water level upper limit inductor and water level lower limit inductor in the water level induction cup, with water level induction cup bottom by communicating pipe with after circulated sprinkling water in casing is communicated with, water level upper limit inductor and water level lower limit inductor just can detect the water level of the circulated sprinkling water in casing, owing to water level sensor not being arranged in the casing of vacuum sizing box, so just avoided the hot and humid environment of water level sensor contact, effectively reduce the fault rate of water level sensor, therefore can accurately control the liquid level of the circulated sprinkling water in vacuum sizing box and the vacuum that vacuumizes, improve the crudy of pipe fitting.
