Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a small-sized grouting plant conveying unit lc%I.
This is a measuring and conveying device for diluted solutions that reduces wasted remaining stock solution and shortens measuring and conveying time.

Conventional devices of this kind have been configured with a combination of one large-capacity stock solution storage tank and multiple measuring transfer tanks, or one-to-one combinations, resulting in a large amount of waste leftover and the need for piping. It had the disadvantage that weighing was slow due to its length.

In order to solve these drawbacks, the present invention installs an appropriate number of stock solution storage tanks with a capacity multiple times the minimum required for supplying to a plurality of weighing transfer tanks, reduces the amount of stock solution waste, and measures the stock solution alternately. The aim is to shorten the waiting time for weighing by
Branch pipes are connected to the pressure air piping, and air discharge pipes are attached to each via a solenoid valve, and the transfer pipes are connected to the transfer line via a check valve.This is placed between multiple weighing transfer tanks and the weighing transfer tank. It is characterized by comprising an appropriate number of stock solution storage tanks each having a capacity several times the minimum capacity required for supply to the measuring transfer tank, each of which is provided with a pipe for supplying stock solution to the transfer tank.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a schematic diagram showing an embodiment of the present invention, in which 1 is a stock solution storage tank, and 2 and 3 are measuring transfer tanks.

A 1 lux cement solution prepared by a mixing unit (not shown) is stored in a stock solution storage tank 1 and constantly stirred. From the undiluted solution storage tank 1, undiluted milk is supplied to the metering transfer tank 2.3 as required.

The measuring transfer tank 2 receives undiluted milk from the undiluted solution storage tank 1 and water from a water supply unit (not shown), and measures, prepares and transports cement milk of a set concentration.
It is 8. The raw milk and water are measured using an electromagnetic flowmeter to create cement milk with an accurate concentration. This cement milk is air pumped through a conveying line 17 to each grout terminal agitator.

During this series of operations, the two weighing tanks alternate between vacuum and pressure states by opening and opening electromagnetic valves. In other words, when measuring or pressurizing one of the transfer tanks 2, open the electromagnetic valve 9b,
When creating a vacuum, close the electromagnetic valve 9b, open the electromagnetic valve 9C to release air, and open the electric valve 9m. The same applies to the other weighing and transporting tank 3.

2o is a stock solution supply pipe 20 for measuring and supplying the stock milk from the stock solution storage tank 1 to the transport tanks 2 and 3, and 21 is a transit pipe 21 for supplying 4 ruq to the transport line 17. be. Each of these is provided with a check valve, and each of the check valves 6, 6 and 7, 8 is configured so that one of them is open and the other is closed. Therefore, when metering is being carried out in one metering transfer tank, it can be transferred to the other tank, and the amount of electricity and the transfer can be efficiently carried out alternately. Moreover, since the check valve can be operated by an internal pressure difference without being controlled by an external control signal, the check valve can be made compact and can be operated reliably.

In the embodiment, the stock solution storage tank 1 has the capacity of two units, which is the minimum capacity required for supplying to the measuring transfer tank, so it can sufficiently respond to the supply to the tank and does not have a capacity that is more than necessary. This has the effect of reducing waste of the undiluted solution.

In the embodiment of the transport unit according to the present invention, the basic components are two measuring transport tanks and one stock solution storage tank, so it can be assembled into a compact structure, and the necessary units can be installed according to the plant situation. It has the advantage that it can be expanded freely, and that the units can be separated at will when removed.

As described above, according to the present invention, waste of the undiluted solution is reduced, efficient measurement and transport can be performed, the transport capacity can be improved, and the transport unit can be easily installed, increased or decreased. transportation enits) tl-
Now we can provide it.
