DETAILED DESCRIPTION

[0015] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. The components of the embodiments of the present application described and shown in the drawings can be arranged and designed in various different configurations.

[0016] Therefore, the detailed description of the embodiments of the present application provided in the drawings below is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0017] As Figure 1 shown, the present application comprises a feed tank 1, the top of the feed tank 1 is a detachable bucket cover 101, the feed tank 1 here is a very overflowed feed tank, the feed tank 1 is connected with the input port of the rear centrifugal pump 6 through the first feed pipe 4, the centrifugal pump 6 provides power for liquid pigment delivery and simultaneously performs centrifugal filtration, repeated circulation, i.e. multiple centrifugal filtration, two output ports are provided thereon, one of which is connected with the hole at the bottom of the feed tank 1 through the circulating feed pipe 601 for circulating filtration, and the other is connected with the rear several storage cylinders 9 in series through the second feed pipe 7 for final storage;

[0018] The first feed pipe 4 is provided with a heat exchanger 2 and a first electromagnetic valve 3, and the heat exchanger 2 maintains the temperature control of the pigment.

[0019] The circulating feed pipe 601 is provided with a third electromagnetic valve 602, the second feed pipe 7 is provided with a second electromagnetic valve 8, and the rear end of the first feed pipe 4 is provided with a flow meter 5 for measurement.

[0020] The bucket cover 101 is provided with a U-shaped opening at the edge, the first feed pipe 4 passes through the U-shaped opening into the feed tank 1, and the U-shaped opening design facilitates the taking and placing of the bucket cover 101 and does not affect the placed feed pipe.

[0021] The electrical elements are connected with the PLC and controlled by the PLC.

[0022] The working principle of the utility model is:

[0023] (1) first, the operator pours the circulating material (i.e. pigment) into the feeding barrel 1, at this time the first electromagnetic valve 3 and the third electromagnetic valve 602 are in the closed state, the liquid level meter 102 value is observed, and after reaching the specified value, the centrifugal pump 6 is started according to the operation procedure, the speed exceeds the set under-speed speed (initially set to 5000 rpm), the under-speed value can be set arbitrarily according to the actual situation through the speed digital display control panel, the centrifuge is successfully started, at this time the first electromagnetic valve 3 and the third electromagnetic valve 602 are opened, the pigment circulates in the feeding barrel 1 and the centrifugal pump 6, and the feeding barrel 1 can continue to be fed during the circulation process.

[0024] (2) in process (1), when the motor of the centrifugal pump 6 fails to start (such as the operator fails to start the centrifuge in the machine according to the operation procedure or the belt slips and other under-speed faults), the under-speed speed is lower than the set value (such as 5000 rpm), and the speed digital display control panel interlocks to close the third electromagnetic valve 602 to prevent overflow, at this time if the liquid level meter 102 alarms, the second electromagnetic valve 8 is opened to temporarily store the material.

[0025] (3) after the circulation is completed, the second electromagnetic valve 8 is opened first, and the third electromagnetic valve 602 is closed later, the internal hot pigment enters the storage cylinder 9 through the second feeding pipe 7, and the work is completed.

[0026] Finally, it is pointed out that the above examples are only used to illustrate the technical solutions of the utility model and not to limit, other modifications or equivalent replacements of the technical solutions of the utility model made by those skilled in the art should be covered in the scope of the claims of the utility model.
