The utility model relates to a kind of colouring flaw detection liquid recovery device, comprising: the collection groove of inclination setting, the first recovery cylinder of the communication collection groove bottom, the second recovery cylinder of the communication collection groove preset height and the shutter of parallel inclination setting on the collection groove;Wherein, the first recovery cylinder preset height communication second recovery cylinder;The shutter is between the bottom and preset height of the collection groove. Solve the problem that the impurity deposited in the bottom of liquid in the prior art is recovered with liquid and the impurity deposited in plastic square groove needs to be cleaned regularly when more.

The utility model discloses an air inlet valve of a screw compressor, which belongs to the technical field of valves and comprises an air inlet valve, an air inlet pipe arranged on the air inlet valve and used for feeding air, a filtering structure arranged on the air inlet pipe and used for filtering entering air, and a connecting structure arranged on the air inlet valve and used for connecting a pipeline with the filtering structure, the filtering structure comprises a corrugated pipe fixedly arranged on the air inlet pipe in a sleeving mode, a connecting pipe arranged at one end of the corrugated pipe, an impurity box movably installed in the connecting pipe and a conical filtering plate arranged in the impurity box and used for filtering impurities. According to the utility model, the conical filter plate is arranged at the air inlet pipe of the air inlet valve, impurities and dust in air flow can be filtered and blocked, so that the abrasion and corrosion of the impurities to internal parts of the compressor are reduced, and the impurities on the conical filter plate can slide into the impurity box along the inclined surface of the conical filter plate to be stored under the blowing of the air flow; the blockage condition of the conical filter plate can be relieved, and frequent cleaning of the conical filter plate is avoided.

The utility model discloses an anti-blocking type polygonatum sibiricum extracting solution filtering device in the technical field of polygonatum sibiricum production and processing, and the anti-blocking type polygonatum sibiricum extracting solution filtering device comprises an extracting tank, supporting columns are installed on the outer wall of the extracting tank, and guide grooves are formed in the lower portions of the surfaces of the supporting columns, the anti-blocking type polygonatum sibiricum extracting solution filtering device is reasonable in structure. The rhizoma polygonati extracting solution is discharged to the filter plate after being extracted in the extracting tank, the rhizoma polygonati extracting solution falls into the filter plate and is filtered by the filter plate according to the fact that the groove is formed in the surface of the filter plate, and the groove and the filter plate are provided with the groove holes for filtering, and the motor B drives and controls the brush to clean filtered rhizoma polygonati medicine residues during the period. The filter plate is kept in the best state and the depth of the groove is kept as far as possible, the problem that medicine residues on the filter plate are frequently cleaned is directly solved, frequent cleaning of related personnel is reduced, and the workload and the workload degree are reduced.

The utility model provides an in-vitro scaling type electrocatalytic oxidation device, which relates to the technical field of sewage electrolysis treatment and comprises a cathode plate, an anode plate, an anion exchange partition plate, a cathode electrolysis chamber plate and an anode electrolysis chamber plate. Wherein the cathode electrolysis chamber is located between the anion exchange partition plate and the cathode plate, and the anode electrolysis chamber plate is located between the anion exchange partition plate and the anode plate. The utility model has the beneficial effects that the anode plate can generate hydroxyl radicals with high oxidability in the anode electrolysis chamber, so that the sewage in the anode electrolysis chamber is oxidized, and the treatment of organic wastewater is realized; and the anion exchange partition plate can prevent cations in the anode electrolysis chamber from moving towards the cathode electrolysis chamber and reduce the concentration of the cations in the cathode electrolysis chamber, so that the problem that the surface of a cathode plate is scaled due to the fact that the concentration of the cations in the cathode electrolysis chamber is too high is solved, the electrocatalytic oxidation device can continuously work for a long time, and the sewage treatment efficiency is improved.

The utility model relates to the technical field of negative pressure supply systems, and discloses a negative pressure supply device. Wherein the negative pressure supply device comprises a vacuum unit, a filter unit and a buffer unit, and the vacuum unit is used for enabling an energy consumption device communicated with an air inlet of the vacuum unit to have negative pressure; the filtering unit is arranged between the vacuum unit and the energy consumption device and comprises a first filter and a second filter, the second filter is communicated with an air inlet of the vacuum unit, the first filter is communicated with one end, far away from the vacuum unit, of the second filter, and the filtering aperture of the first filter is larger than that of the second filter; the buffer unit is communicated with the upstream of the air inlet of the vacuum unit and used for buffering the negative pressure provided by the vacuum unit. According to the utility model, the cleanliness of air entering the vacuum machine can be effectively improved; and meanwhile, the negative pressure generated by the vacuum unit is buffered.
