Description

Technical field:

[0001] The utility model relates to the field of cleaning, in particular to a centrifuge washing water device. Background technology:

[0002] The ammonium sulfate centrifuge uses centrifugal force to separate liquid and solid. It is a commonly used chemical equipment in chemical plants. It is mainly composed of a centrifuge shell and a drum, a hopper, a push plate, a feed pipe, etc. inside the shell. The ammonium sulfate centrifuge uses centrifugal force to separate solid and liquid waste. When the machine is running, the drum rotates at a certain speed, generating a strong centrifugal force field. Under such a strong force, the solid particles are quickly thrown to the inner wall of the drum, while the liquid is left in the center. Due to the different pressures inside and outside the drum, the solid is compressed, and the liquid flows out through the screen gaps on the side wall of the drum.

[0003] During the operation of the centrifuge, a small amount of fine solid particles flow out through the gaps in the screen but are not taken away by the liquid, and are easily retained in the gap between the drum and the centrifuge casing. The long-term operation of the centrifuge causes too much material to accumulate in the gap, making it difficult for the centrifuge push plate and drum to rotate. The load is heavy and the current of the main motor is too high, which may seriously cause the motor to burn out and the drum to be damaged, resulting in production accidents. Utility model content:

[0004] The utility model aims to provide a centrifuge washing water device.

[0005] The utility model is implemented by the following technical solutions:

[0006] A centrifuge washing water device comprises a rotary drum, a centrifuge housing, a water pump, a valve, a water spray pipe, and a water spray head, wherein the water outlet of the water pump is connected to one end of the water spray pipe through the valve, the water spray pipe penetrates the centrifuge housing, and the other end of the water spray pipe is bent and connected and fixed to the water spray head;

[0007] The diameter of the water spray pipe between the bend of the water spray pipe and the water spray head is narrowed;

[0008] The water spray head is an arc-shaped tube, and a plurality of spray holes are arranged on one side of the water spray head, and the spray holes face the gap between the rotating drum and the centrifuge shell.

[0009] Preferably, both ends of the water spray head are closed.

[0010] Advantages of the utility model: the utility model increases the flow rate and water pressure by pressurizing water once with a water pump and pressurizing the water pipe at a narrowed position for a second time, which facilitates flushing of gaps and avoids damage to the centrifuge. At the same time, the arc-shaped tube shape of the water spray head matches the circular gap, and multiple spray holes increase the water spray area, which is conducive to flushing.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] like Figure 1 , Figure 2 , Figure 3 As shown, a centrifuge washing water device includes a rotating drum 1, a centrifuge housing 2, a water pump 3, a valve 4, a water spray pipe 5, and a water spray head 6. The water outlet of the water pump 3 is connected to one end of the water spray pipe 5 through the valve 4. The water spray pipe 5 penetrates the centrifuge housing 2. The other end of the water spray pipe 5 is bent and connected and fixed to the water spray head 6.

[0018] The water pump 3 is connected to an external water source. After the valve 4 is opened, the water is pumped to the water spray pipe 5 through the water pump 3 and then enters the water spray head 6. The water pump 3 exerts a primary pressure on the water.

[0019] The diameter of the water spray pipe 5 between the bend of the water spray pipe 5 and the water spray head 6 is narrowed, and a Venturi effect is formed at the narrowing point, and the water flow passing through the narrowing point is pressurized twice, and the flow rate becomes faster;

The water in the water spray head 6 is quickly sprayed out from the plurality of spray holes 7 to wash the gap between the drum 1 and the centrifuge housing 2, and the fine and broken solid particles are washed away. During this process, the drum 1 can be rotated to facilitate the removal of more solid particles, and the water carries the solid particles out along the original solid-liquid separation liquid discharge port of the centrifuge housing 2; the arc-shaped tube shape of the water spray head 6 matches the circular gap created by the circular drum 1, and the plurality of spray holes 7 increase the water spraying area, which is conducive to flushing.

[0021] The present application increases the flow rate and water pressure by pressurizing water once with a water pump 3 and pressurizing water at the narrowing part of the water spray pipe 5 for the second time, so as to facilitate flushing of gaps and avoid damage to the centrifuge.
