Description

Improved ceramic filter filtrate pump system

technical field

The utility model relates to an improved filtrate pump system of a ceramic filter.

Background technique

The filtrate discharge system of the ceramic filter used in the iron and steel concentrator is composed of a filtrate pump, a filtrate tank and related pipelines. During the use of the ceramic filter, due to the overload of the filtrate pump, the corrosion and wear of the impeller and the pump casing, the ceramic filter cannot operate normally, and sometimes shuts down, affecting the shutdown of the entire production line, and causing serious losses in production and maintenance costs.

Contents of the invention

The purpose of this utility model is to provide an improved ceramic filter filtrate pump system, which can complete the liquid drainage work without using the filtrate pump, avoid equipment failure caused by failure of the filtrate pump, and improve the operation reliability of the ceramic filter.

The purpose of this utility model is achieved in that an improved ceramic filter filtrate pump system includes two filtrate tanks connected to the filter, the filtrate tanks are respectively connected to vacuum pumps, and the filtrate pipe installed at the bottom of the filtrate tank extends into a well Under the surface of the water, a liquid level gauge and a submersible pump are installed in the well. The liquid level gauge is linked with the submersible pump, and the outlet pipe of the submersible pump is connected to the clean water system of the ceramic filter.

The utility model utilizes the principle of atmospheric pressure and liquid level difference to realize the automatic discharge of the filtrate water of the ceramic filter, replaces the forced pumping of the filtrate pump, ensures the operation reliability of the ceramic filter, and avoids equipment failure caused by the failure of the filtrate pump; At the same time, the liquid level gauge and submersible pump are used to recycle the filtrate water and save water resources.

Description of drawings

The utility model will be described in further detail below in conjunction with the accompanying drawings.

Fig. 1 is a schematic diagram of the connection structure of the present invention.

Detailed ways

An improved ceramic filter filtrate pump system, as shown in Figure 1, includes two filtrate tanks 7 connected to the filter 4, the filtrate tanks 7 are respectively connected to vacuum pumps, and the filtrate pipe 3 installed at the bottom of the filtrate tank extends to a well Under the water surface in 1, a liquid level gauge 2 and a submersible pump 5 are installed in the well 1, the liquid level gauge 2 is linked with the submersible pump 5, and the outlet pipe 6 of the submersible pump 5 is connected to the clean water system of the ceramic filter.

As shown in Figure 1, the force situation of the filtrate water at the filtrate outlet in the well is analyzed, the upward force includes atmospheric pressure P, the filtrate water pressure F1 of the water surface in the well to the height difference H1 of the filtrate outlet; the downward force includes the pressure P1 reported by the filtrate tank, The filtrate water pressure F of the height difference H between the water surface in the filtrate tank and the filtrate outlet. Since the filtrate filling is airtight and the upper part becomes almost vacuum after being drawn by the vacuum pump, the pressure P1 is almost zero. Therefore, the force of the filtrate water at the filtrate outlet is E= F—(P+ F1). When F>P+ F1, the filtrate water will be discharged naturally; since the atmospheric pressure P is approximately equal to the height of the water column of 10m, it is converted into a height difference: when H>10+ At H1, the filtrate water is discharged naturally; through the liquid level gauge and submersible pump, the height difference H1 from the water surface in the well to the filtrate outlet can be controlled within a certain range, so when the outlet of the filtrate pipe is placed in a well with a depth higher than 10+H1, the filtrate Water has just realized artesian flow.

The water level in the well is controlled by a submersible pump and a liquid level gauge, and it is always kept within a certain range, and at the same time, the filtrate discharge outlet is always kept below the water surface of the well; the overall sealing of the filtrate water pipe is maintained to avoid water being affected by atmospheric pressure in the filtrate pipe. Therefore, the height difference between the water surface in the well and the water level in the filtrate irrigation can be used to realize the natural discharge of the filtrate water from the filtrate irrigation to the well.

Through the transformation, the natural discharge of the ceramic filter has been realized, and the failure of the filtrate pump has been fundamentally eliminated; at the same time, the submersible pump has clarified the collected filtrate water and returned it to the ceramic filter water system to realize water recycling and save water. The beneficiation process provides a way to save water resources.
