[Prior Art and Problems to be Solved by the Invention]

 Conventionally, single screw pumps have been used to carry out highly viscous liquids such as miso, cream, gluten, sake lees, petroleum jelly, paints and grease stored in a portable container, and they are positioned on both sides of the container. A device for moving the uniaxial screw pump up and down by the lifting hydraulic cylinder device is used. Such a conventional device has various drawbacks as listed below. The single screw pump has a complicated structure, and its disassembly and maintenance are troublesome. With a structure in which two lifting hydraulic cylinder devices are arranged on both sides of the container, it is difficult to accurately match the operating speed between the two cylinder devices, so a scraping plate that moves up and down by sliding contact with the inner peripheral surface of the container. Cannot be smoothly lowered, and an inconsistency between the lowering speed and the lowering speed of the liquid surface in the container causes liquid leakage. When the used pump is raised and removed from the container, a negative pressure is created in the container due to the sealing effect between the scraping plate with the sealing member attached to the periphery and the container. Is required. It is unsanitary because the oil in the hydraulic cylinder device leaks and contaminates the surrounding area. The device for pumping in and out from the top of the container has a large overall height, which is inconvenient during transportation. The liquid level is detected manually by using the disappearance of the sound of the air in the container being exhausted, and it is difficult to ensure accuracy. After all the liquid in the container has been drained, the anchor bolts are installed to prevent the situation where the propelling force of the pump and the scraping plate due to the operation of the hydraulic cylinder device acts on the bottom of the container and the entire liquid discharge device tilts and falls. It is necessary to fix the whole equipment to the foundation floor by using it, and it is inconvenient to move the equipment. The purpose of the present invention is to overcome the drawbacks of such conventional devices.

In a structure in which the rotary pump is supported by a guide shaft in a cantilever manner via an elevating support member, a sufficient free space for container installation is secured on the elevating support member side with respect to the guide shaft, so that the container can be installed. , Easy removal operation. By adopting a structure in which the lifting support member is moved up and down by a single pneumatic cylinder device, there is no need to adjust the speed between multiple cylinder devices, and smooth movement of the lifting support member is guaranteed and stable. The discharged liquid can be carried out, and the apparatus can be automatically operated. On the upper surface of the horizontal scraping plate, a ventilation pipe having the second opening at the lower end opening is attached and erected, and if an opening / closing valve is attached to the pipe, the horizontal scraping can be appropriately performed by opening / closing the opening / closing valve. The inner space of the container under the plate can be closed or open for ventilation. Therefore, ensure that the inside of the container is hermetically closed when the pump is operating, and when removing the pump and the horizontal scraping plate from the container, ensure that the space inside the container below the horizontal scraping plate does not become a negative pressure state. You can Further, by attaching a liquid level detection sensor to the horizontal scraping plate, the liquid level position or the pressure inside the container can be automatically detected and the liquid discharge can be automatically started. The support frame and the guide shaft are vertically divided into two parts, and the upper and lower halves of the support frame are foldably and foldably connected to each other by a hinge, so that the hinge is used while the elevating and lowering support member is lowered. If the strut frame can be folded and folded together with the guide shaft on the side opposite to the side where the elevating and lowering support member is arranged, it is convenient for handling during transportation. If a support plate for placing the container is provided integrally with the horizontal base, even if the scraping plate pushes the container bottom after all the liquid in the container is discharged, it will still be driven by its own propulsive force. The device will not be lifted and will not fall, and the anchor bolts for fixing the device can be omitted.
