Description

a filter device

technical field

The utility model relates to a filter device, in particular to a basket-type filter device.

Background technique

Existing basket filters are generally connected in a closed pipeline system and run under pressure. In order to prevent material leakage, multiple bolts and other connecting parts need to be used to fasten the set. When operating under pressure, the filter parts (such as filter screen, etc.) are easily damaged and the material will penetrate through the filter. Because it is not easy to find in the closed system, it will affect the quality of the filtrate and cause process accidents.

Contents of the invention

The object of the present invention is to solve the above problems and provide a filter device that is easy to disassemble, can filter under a relatively low pressure, and can ensure the quality of the filtrate.

Technical scheme of the present invention is as follows:

A filter device, mainly composed of a housing, a movable top cover, and a basket-type filter basket, is characterized in that a filtrate chamber and an initial liquid return chamber are arranged in the housing, and the filtrate chamber and the initial liquid return chamber are separated by a partition. are not connected to each other, the bottom of the filtrate chamber is provided with a filtrate outlet, the top of the filtrate chamber is provided with a top opening that matches the basket-type filter basket, and the bottom of the initial liquid return chamber is provided with an initial liquid outlet. The upper and lower baskets have different structures. The upper section is a pressure-holding section. The pressure-holding section has no filter holes. The pressure-holding section is also provided with an initial liquid overflow port. The lower section is a filter section. The filter section is inserted into the filtrate chamber through the top opening of the filtrate chamber; the upper end of the shell is provided with a primary liquid inlet pipe, and the opening of the primary liquid inlet pipe is facing the upper opening of the basket type filter basket.

Further, an observation mirror is connected to the initial liquid outlet at the bottom of the initial liquid return chamber.

It can be seen from the above technical scheme that the utility model adopts a movable top cover, which is easy to disassemble, and ordinary operators can disassemble the filter and clean the basket-type filter basket as required. The basket-type filter basket of the utility model is provided with a filter section and a pressure-holding section, and the pressure-holding section is also provided with a primary filter overflow outlet. At the outlet, the material coming in from the primary liquid inlet of the filter will partially overflow to the primary liquid return chamber, and then return from the primary liquid return chamber to the primary filter tank through the pipeline. The design of the utility model ensures that the pressure in the basket-type filter basket can be maintained below the liquid level from the bottom of the basket-type filter basket to the overflow outlet of the primary filter, thereby reducing the probability of filter parts being damaged and causing the material to filter through. In addition, since the pipeline connected to the initial liquid return chamber is equipped with an observation mirror, it can be judged whether the filter needs to be cleaned according to the amount of material returned by the pipeline.

Detailed ways

Example 1

A filter device, mainly composed of a housing 1, a movable top cover 5, and a basket-type filter basket 4, the housing 1 is provided with a filtrate chamber 2 and an initial liquid return chamber 3, and the filtrate chamber 2 and the initial liquid return chamber 3 are separated by partitions and are not connected to each other. A filtrate outlet 7 is provided at the bottom of the filtrate chamber 2. A top opening 12 matching the basket-type filter basket 4 is provided at the top of the filtrate chamber 2. The initial liquid returns to the chamber. 3. An initial liquid outlet 8 is arranged at the bottom, and the basket-type filter basket 4 has two different structures, the upper and lower sections, the upper section is a pressure-holding section 10, and the pressure-holding section 10 has no filter holes, and the pressure-holding section 10 is also provided with The initial liquid overflow port 9, the lower section is a filter section 11, and the filter section 11 is provided with a filter hole, and the filter section 11 is inserted into the filtrate chamber 2 through the top opening 12 of the filtrate chamber 2; the upper end of the housing 1 is provided with an initial liquid Inlet pipe 6, the opening of first liquid inlet pipe 6 is facing the opening of the basket type filter basket 4 tops.
