Abstract

The utility model discloses a high-efficiency circulation filter device for chemical experiments, which comprises an inlet pipe, a mixing area, an outlet pipe, a filter and a sewage outlet, and the inlet pipe and the outlet pipe are connected through an annular pipe. The lower end of the annular pipe communicates with the sealed mixing area, and an inclined solid filter is installed at the bottom of the mixing area, and a primary sewage outlet and a solenoid valve are installed on the upper side of the solid filter, and a liquid storage is installed on the lower side of the solid filter. The liquid in the storage bucket is connected to the inlet pipe through the return pipe through the water pump to form a cycle. In the utility model, an annular pipe is connected between the inlet pipe and the outlet pipe, so that the separation of solid and liquid is more favorable, and the solid basically does not enter the outlet of the annular pipe. The utility model designs a structure of twice filtering sewage, which not only can store water but also can filter in stages, and the filtering effect is very good.

Description

High-efficiency circulation filter device for chemical experiments

technical field

The utility model belongs to the technical field of filter tools for chemical experiments, in particular to a high-efficiency circulation filter device for chemical experiments.

Background technique

Manufacturing processes, whether chemical drugs or biopharmaceutical products, often include filtering out products that are in the form of solid substances in suspension. Due to the high standards of product quality and purity, as well as the cleaning possibilities and inspection possibilities of the filter units, discontinuous batches of filter treatments are often used in experimental or production processes. In this regard, however, the disadvantage of low productivity may arise, for example, due to a low ratio of productive periods to non-productive periods. A commonly used filtering device includes a top cover and a body. The top cover is provided with a feed port, the lower part of the main body is provided with a liquid outlet, the middle part of the main body is provided with a sieve plate, and the sieve plate is covered with a filter mesh. The material enters the filter device from the feed inlet, and after being filtered by the sieve plate and the filter screen, the liquid flows out through the liquid outlet, and the solid matter stays on the sieve plate in the main body. After filtering, open the top cover and take out the solid matter. During the use of the filtering device, there must be a process of manually taking out the solid matter at last, which is cumbersome to operate and increases the labor intensity.

Utility model content

The purpose of the utility model is to provide a filter capable of realizing internal circulation and improving the filtering effect for the problems of poor filtering effect and low efficiency in the existing chemical industry or pharmaceutical production process.

In order to achieve the above purpose, the following technical scheme is adopted: a high-efficiency circulation filter device for chemical experiments, including an inlet pipe, a mixing area and an outlet pipe, as well as a filter and a sewage outlet, and the inlet pipe and the outlet pipe pass through The annular pipe is connected, and the lower end of the annular pipe is connected with the sealed mixing area. An inclined solid filter is installed at the bottom of the mixing area. A sewage outlet is installed on the upper side of the solid filter and a solenoid valve is installed on the lower side of the solid filter. A liquid storage bucket is provided, and the liquid in the liquid storage bucket communicates with the inlet pipe through the return pipe through the water pump to form a circulation.

The lowest end of the bottom of the liquid storage bucket is provided with a secondary sewage outlet and sealed with a cover. A backflow filter is provided on the downstream side of the secondary sewage outlet.

An outlet filter is provided on the outlet side of the annular pipe.

Beneficial effects: the utility model has an annular pipe connected between the inlet pipe and the outlet pipe, which is more conducive to the separation of solids and liquids, and basically solids will not enter the outlet of the annular pipe. The utility model designs the structure of twice filtering sewage, which not only can store water but also can filter in stages, and the filtering effect is very good.

detailed description

Embodiment: as shown in Figure 1, the high-efficiency circulation filter device for chemical experiments is communicated between the inlet pipe 1 and the outlet pipe through an annular pipe 12, and the high end of the outlet pipe is located on the upper side of the end of the annular pipe 12, solid-liquid After passing through the annular pipe 12, the mixture does not substantially ascend upward into the outlet pipe. An outlet filter 6 is arranged on the outlet side of the ring pipe 12 .

The lower end of the annular pipe 12 is provided with a sealed mixing zone 2, except a part of the liquid is discharged from the outflow tube, another part of the liquid and solid impurities enter the mixing zone 2.

An inclined solid filter 8 is arranged at the bottom of the mixing zone 2 , a primary sewage outlet 15 is arranged on the upper side of the solid filter 8 and a solenoid valve 16 is installed, and a liquid storage bucket 9 is arranged on the lower side of the solid filter 8 . The liquid after the first filtration all enters the liquid storage bucket 9 .

The liquid in the liquid storage bucket 9 communicates with the inlet pipe 1 through the return pipe 14 through the water pump 4 to form a circulation. Specifically, a secondary sewage outlet 13 is provided at the lowest end of the bottom of the liquid storage bucket 9 and is sealed with a cover. A backflow filter 7 is provided on the downstream side of the secondary sewage outlet 13 . A support pipe 5 is provided outside the return pipe 14, which has the functions of support and sealing.
