JP3059701U - Liquid and solid-liquid mixture recovery device - Google Patents

Abstract

(57) [Summary] [Object] To provide an apparatus for recovering a liquid and solid-liquid mixture, which always ensures efficient pumping of the recovered material without causing blockage or reduction in suction capacity. A suction pipe 2 opened toward a supply source 3 for a liquid or a solid-liquid mixture is drawn out of a recovery tank 1, and an air supply port 6 is opened from near the leading end of the suction pipe 2 to the inside of the pipe. Then, an air supply pipe 8 derived from the compressor 7 is connected to the air supply port 6 via a check valve 9, and when the vacuum generation device 5 is driven, the air supply amount is smaller than the intake air volume of the vacuum generation device 5. A constant air volume valve 10 and a regulator 11 for constantly supplying the air with the air volume into the suction pipe 2 are attached to the air supply pipe 8.

Description

[Detailed description of the invention]

[0001]

[Technical field of invention]

 The present invention relates to an apparatus for collecting a liquid and a solid-liquid mixture, for example, for collecting spring water at a construction site and collecting sediment at a dredging site.

[0002]

[Prior art and its problems]

 2. Description of the Related Art A suction type recovery device in which a liquid or solid-liquid mixture is pumped into a recovery tank through a suction pipe by driving a vacuum generator is known. However, the conventional suction-type collection method using only the suction function of the vacuum generator has many unstable factors. If the amount of air taken in with the collected material is large, the collected material will be taken in a small amount and the efficiency will be poor. If the suction amount is small, a large amount of collected material will be taken into the suction pipe, so the pressure loss in the suction pipe will increase and the pumping speed will decrease, often causing blockage in the suction pipe. The suction force at the leading end of the discharge decreases, and the collected material cannot be lifted.

[0003]

[Purpose of the invention]

 It is an object of the present invention to remove the above-mentioned unstable elements and to always ensure efficient pumping of the collected material without causing blockage or a decrease in suction capacity. Is to provide.

[0004]

[Structure of device]

 In the liquid and solid-liquid mixture recovery device according to the present invention, the liquid or solid-liquid mixture is collected by the suction type recovery device that sucks the liquid or solid-liquid mixture into the collection tank through the suction pipe by driving the vacuum generator. The suction pipe opened to the supply source of the body is drawn out from the collection tank, an air supply port is opened from near the leading end of the suction pipe to the inside of the pipe, and the air supply pipe drawn from the compressor is checked. A constant air volume valve and a regulator are connected to the air supply port through the air supply port, and when the vacuum generation device is driven, a constant air volume valve and a regulator for supplying air having a smaller air volume than the intake air volume of the vacuum generation device into the suction pipe are provided in the air pipe. It is attached.

[0005]

[Action]

 When the inside of the recovery tank and the suction pipe are evacuated by driving the vacuum generator, the liquid or solid-liquid mixture of the collected material supply source is sucked into the suction pipe while containing air. At this time, if the compressor is driven and the regulator and constant air flow valve are used to constantly supply air with an air flow rate smaller than that of the vacuum generator to the intake pipe, the liquid or solid-liquid mixture in the suction pipe will be smooth. And is collected in the collection tank.

[0006]

【Example】

 Hereinafter, description will be made with reference to the drawings of the embodiments.

[0007] 1 is a collection tank for collecting muddy water or dredged material, etc., and 2 is a suction pipe having a front end that is opened to a supply source 3 for muddy water or dredged material and a rear end that is opened into the collection tank 1. Reference numeral 4 denotes an intake pipe which is led out from the upper part of the recovery tank 1 and communicates with the suction side of the vacuum generator 5, and 6 denotes an air supply port which is opened from near the leading end of the suction pipe 2 to the inside of the pipe. An air supply pipe 8 derived from the compressor 7 is connected to the air supply port 6 via a check valve 9. Reference numeral 10 denotes a constant air volume valve attached to the air supply pipe 8 for constantly supplying air having an air flow rate smaller than the intake air volume of the vacuum generating device 5 into the suction pipe 2. Reference numeral 11 denotes a regulator attached to the air supply pipe 8 on the primary side of the constant air volume valve.

[0008]

[Effect of the invention]

 According to the recovery device of the present invention, the lifting of the collected material by the suction action of the vacuum generating device is assisted by the air supply action from the compressor, so that the collected material is filled with a large amount of air from the outlet opening of the suction pipe. Even if the air is sucked in or the amount of air intake is small, appropriate and efficient recovery of the collected material is always ensured.
