The utility model relates to the technical field of ferrous metallurgy, in particular to a continuous casting machine crystallizer inlet water filtering device which comprises a filter chamber, a filtering assembly, a reversing assembly, a water inlet pipe and a water outlet pipe. The water inlet pipe and the water outlet pipe are respectively connected with the filter chamber; the filter assembly comprises a filter screen supporting piece and at least two filter screens, the filter screens are connected with the filter screen supporting piece, and the filter screen supporting piece is connected with the inner side wall of the filter chamber; the reversing assembly comprises an upper partition plate, a lower partition plate and a reversing rod, the reversing rod penetrates through the filter screen supporting piece, namely, the filter assembly is located between the upper partition plate and the lower partition plate, and the water filtering channel is replaced under the condition that water supply is not interrupted through the separation and reversing effects of the reversing assembly. The water filtering device is simple in structure, water entering the crystallizer is filtered, the casting blank quality problem caused by blockage of a water seam and a nozzle of the crystallizer is avoided, water supply of the crystallizer does not need to be interrupted when the water filtering channel is replaced, and therefore production efficiency is improved.

The utility model relates to the technical field of earthwork standard rooms, in particular to a node reinforced earthwork standard room, and aims to solve the problems that the earthwork standard room is insufficient in connection strength, and the earthwork standard rooms are easy to fall off or deform after being used for a long time. Comprising a plurality of geocell zones, and a plurality of ribs are formed on the geocell zones; the connecting pieces are used for penetrating through the ribs of the two adjacent geocell belts; an annular groove is formed in the baffle ring; the fixing pieces are arranged on the connecting pieces in a sleeving manner; wherein the connecting piece is used for penetrating the ribs into the annular groove, the baffle ring limits and fixes the connecting piece through the annular groove, and the adjacent fixing pieces are mutually connected and fix the ribs and the connecting piece. The fixing pieces are arranged on the connecting pieces in a sleeving mode, the connecting pieces are arranged on the ribs of the geocell belt in a sleeving mode, finally the baffle rings are arranged at the tail ends of the connecting pieces in a sleeving mode, the connecting pieces are fixed, the exposed connecting pieces are flattened and limited, and the connecting strength of the geocell belt is improved.

The present invention discloses a cooling chamber and a method for controlling the air volume of a cooling unit in the cooling chamber. The cooling chamber comprises: a body, wherein a through hole is provided on the body, a receiving space is provided in the body, a cooling channel and a storage space are provided in the receiving space, and the cooling channel is connected to the outside of the body through the through hole; a wind speed sensor, wherein the wind speed sensor is provided at the through hole; a cooling unit, wherein the air outlet of the cooling unit is connected to the cooling channel, and the cooling unit is used to supply air to the cooling channel according to the detection data of the wind speed sensor, so as to cool the storage space through the cooling channel. The present invention solves the technical problems that the air volume output of the existing cooling unit is poorly synchronized with the actual demand and the fan speed control is poorly stable.

The utility model discloses a kind of testing devices for forging flange, it is related to testing device technical field.The utility model includes two flange connecting pipelines and the sealing ring one being arranged at the junction of two flange connecting pipelines, the junction of two the flange connecting pipelines is provided with sealing ring two, further include: test part, the test part is installed on sealing ring one;Anti-falling part, the anti-falling part is arranged on sealing ring one and sealing ring two;The test part includes test component, and the test component is installed on sealing ring one;And support component, the support component is installed on test component.The utility model is by setting test part, solved the air tightness of current testing device in use process, not convenient to detect flange, leading to detection process cumbersome, low efficiency, it is difficult to quickly judge whether flange sealing performance is qualified, can make unqualified product flow into use link, and further cause medium leakage, the problem of influence system operation safety.
