Description

[Detailed Description of the Invention] The present invention relates to various brewing methods such as soy sauce methods, and improvements to a device for transferring viscous sludge-like solid-liquid mixtures such as activated sludge in wastewater treatment plants, or viscous liquids.

The present invention can be widely applied to viscous sludge-like solid-liquid mixtures or viscous solutions, and will be explained below using soy sauce methods as an example.

Transfer of conventional soy sauce methods (hereinafter simply referred to as "methods") has been roughly divided into the following two methods.

First, in the suction and pressure feeding method shown in FIG.
Activate the pulp 7, 8.9 to open the pulp 4, 5.6.
Close.

Then, the various substances are moved into the suction pressure feeding tank 2 by suction, and when a certain amount is reached, the level switch 10 is activated to notify that the amount has been determined.

As a result, pulp 4°5.6 is closed and pulp 7.8.9
Once opened, the materials are transferred to the next pressing process.

After all the methods in the suction and pressure feeding tank 2 have been transferred, they are sucked from the various methods tank 1 to the suction and pressure feeding tank 2 again.

The advantage of this suction and pressure feeding method is that suction and pressure can be carried out with just one 3゜ suction and pressure pump, and since it is transferred by air action, there is no need to knead the various methods, and it does not adversely affect the next pressing process. .

However, this method is a badge type, and the pulp operation is complicated, and it is difficult to automate and save labor.

In particular, if the various method tank 1 is large, suction and pressure feeding must be repeated many times, and the height at which suction can be taken is also limited.
There is a problem if it is limited to a pressure equivalent to atmospheric pressure.

Another transfer method is shown in FIG. 2, which is used in a multi-method tank having a multi-method outlet at the bottom.

This is a pump method that uses roots pumps, plunger pumps, etc.

This is the various method discharge pipe 12 fixed to the various method tank 11.
A portable multi-process pipe 16 is connected between the flange 13 of the pipe and the flange 15 of the pipe on the suction side of a multi-process transfer pump 14 such as a pulp pump or plunger pump, and the pulp 17, 18, and 20 are The method is opened, and the various methods are transferred by the head of the various methods in the tank 11 and the operation of the method transfer pump 14.

This pump method has the advantage that it can continuously send a large amount of various methods, that it is easy to adjust the feed amount, operate, stop, etc., and that it can be labor-saving and automated.

Furthermore, since the pump 14 is small, it requires less space for installation.

However, with this method, when the amount of various methods in the various methods tank 11 decreases, the various methods 19 remain in the tank or in the various methods vibrator due to the viscosity of the various methods, as shown in Figure 3, and cannot be sucked out. It has its drawbacks.

To discharge this residual material, the pump 14 is stopped and the pulp 17.
20 is closed, the methods pipe 16 is removed from the flange 13.15, the methods in the methods pipe 16 are removed and rinsed with water.

Furthermore, the inside of the pulp tank 11 must be emptied by opening the pulp 17 and waiting for the pulp remaining in the tank to be discharged under its own weight.

In this way, it takes a lot of effort and time to remove the various substances remaining in the various substances tank 11 and the various substances pipe 16, and a considerable amount of substances are spilled and lost during that time, which is a major drawback. It's happening.

Particularly in a system in which a large number of methods are transferred from a large number of method tanks using a small number of pumps, a great deal of labor is required each time the method pipe 16 is replaced or cleaned, resulting in the loss of a large number of methods.

Providing valves at both ends of the pipe 160 reduces the loss of the pipe, but it becomes heavy and inconvenient to transport.

In order to overcome this drawback, conventional methods have been to install transfer pumps fairly low on the bottom of the tank - or to install individual transfer pumps directly below each tank.

We have taken measures such as making the various pipes from the tank to the pump as short as possible.

However, the former method is undesirable because it limits the installation locations of the pumps and tanks, while the latter method requires a large number of pumps, resulting in high equipment costs.

In order to eliminate the above-mentioned drawbacks, the present invention combines a transfer pump for various methods and a suction pressure feeding tank, thereby taking advantage of the advantages of automation and labor-saving, and allows for smooth transfer of various methods in tanks and piping without leaving any residue. It is designed to be transportable.

The embodiments shown in the drawings will be described in detail below.

In FIG. 4, in order to discharge the various methods from the various methods tank 11, a various methods discharge pipe 1 fixed to the bottom of the various methods tank 11 is shown.
A portable transfer pipe 16 is connected between the flange 13 of 2 and the flange 15 of the suction side pipe of a transfer pump 14 such as a Roots pump, and valves 17.18, 20.2 are connected.
1 and closes the valve 6.8, the various methods are transferred by the head of the various methods in the tank and the operation of the method transfer pump 14.

This allows most methods to be transferred efficiently.

As the moromi liquid level in the mash tank 11 approaches the bottom of the tank, air is sucked in together with the mash, and the suction force of the mash transfer pump 14 decreases. Stop 1. When the suction pump 3 is activated, valves 4 and 5 are opened and valves 7, 8, 9, and 21 are closed, the pressure inside the suction and pressure pump 2 is reduced, so when the valve 6 is opened, the bottom of the bland tank 11 and various pipes The various substances remaining in the pipe 16 are completely and efficiently sucked into the suction and pressure feeding tank 2, and the inner surface of the thin pipe 16 is cleaned to the same state as if it had been washed with water.

This is thought to be due to the sudden suction causing the various methods to completely move without remaining.

Liquids containing solids, such as brewers and activated sludge, have high viscosity and have a large transport resistance in piping, so thick piping is necessarily installed.

Piping is normal. Since it is installed horizontally, when the amount of various materials in the method tank 11 decreases, as shown in Figure 3, with normal pump transportation, air enters the thick piping, making it impossible to transport the materials. A large number of laws will remain within it.

In the present application, the suction pressure feeding tank 2 is provided between the various method tank 11 and the various method transfer pump 14 so that it can be independent from the various method transfer pump 14, so the amount of various methods in the various method tank 11 is reduced. When the suction and pressure feeding tank 2 is sufficiently depressurized and then communicated with the various method tank 11, the various method 1 is released as shown in Fig. 5.
9 is completely transferred as if water were moving in a capillary tube without entraining air, and almost never remains.

Next, the operation of the suction pressure pump 3 is stopped, the valve 7.8 is opened, and the various method transfer pump 14 is operated.

The methods in the suction pressure pump 2 are transferred.

In this case, open pulp 7.8, 9, 20, 22 and valve 4.
, 5, 6, and 21 are closed and the suction pressure pump 3 is activated to transfer the various methods using the pressure feeding method.

This completes the transfer of the various methods in the various method tank 11.

In addition, the capacity of the suction pressure feeding tank 2 in Fig. 4 is the same as that of the various method tank 1.
It is preferable to have a capacity larger than that remaining in the pipe 16 or the pipe 16.

When there are a plurality of various method tanks 11, the following operation is further performed.

First, close valves 6.17 and 21 and flange 13.15.
is removed, the thin pipe 16 is removed, and the other various method tanks and the flange 150 are connected with the various method pipes.

Then, the various laws are transferred using the same operations as above.

According to the present invention, the various methods remaining in the method tank and the method pipe are suctioned and transferred at once by the reduced pressure suction force in the suction and pressure feeding tank, so that the methods do not adhere to and remain on the inner surface of the method pipe.

Therefore, when the pipe is removed, the pipe does not flow out, and there is no need to clean the pipe, so there is no loss of the pipe.

According to the present invention, most of the processes can be efficiently and continuously transferred by means of a transfer pump, even automatically, and the last small amount of residual processes can be completely transferred.

Moreover, it can be easily transferred by suction, which reduces labor and prevents various losses.

With conventional methods, it took time to obtain the suction and pressure feeding method itself, required manpower to dispose of the waste and residual materials that could not be transferred by the pump, and caused losses in various methods. Therefore, all the drawbacks of the conventional method can be overcome by simply providing a small suction pump and a small suction pump, which is highly effective in saving labor and preventing loss of various methods.

The present invention is particularly effective when transferring various methods from a large number of tanks using a small number of pumps.
