All the rectification chips are placed on the upper surfaces of the frame units, lap joint connection is achieved through the jumping pieces, in the welding process of the tunnel furnace, the jumping pieces fall on the surfaces of the rectification chips through natural gravity, and the influence of stress borne by the chips due to frame stretching caused by high and low changes of the furnace temperature is avoided.

The application discloses a UV dispensing curing machine and a curing method, and belongs to the technical field of dispensing machines. The machine comprises a dispensing box, a lifting assembly is arranged in the dispensing box, a dispensing structure for dispensing is arranged on the outside of the lifting assembly, the dispensing structure has a primary curing function, and two curing chambers for increasing the curing degree are arranged on the side wall of the dispensing box. According to the application, the depth of the glue column into the glue pipe can be controlled by controlling the expansion range of the power film, and the glue output of the glue pipe can be controlled, so that the component can be coated more accurately. When the glue column moves upward in the glue pipe, the inside of the glue pipe is in a negative pressure state, the glue in the glue pipe is sucked at this time, so that the glue liquid cannot flow out of the glue outlet of the glue pipe, and the parts on the upper end of the component are prevented from being polluted by the excess glue liquid. Meanwhile, the glue liquid can be cured more thoroughly through twice curing at different times.

The present invention discloses a low dielectric constant filter membrane based on biological enzymes. The preparation method includes drying the low dielectric constant filter membrane, dropping biological enzymes onto the surface of the dried filter membrane and then freeze-drying. After the moisture has completely evaporated, the low dielectric constant filter membrane based on biological enzymes is obtained. At the same time, the present invention also discloses the application of the low dielectric constant filter membrane based on biological enzymes in a waveguide gas sensor. After fixing the low dielectric constant filter membrane based on biological enzymes on the resonance window of the resonator in the waveguide gas sensor, the sensor is assembled and tested. By using a filter membrane with a small volume that is convenient for installation and disassembly, the present invention is conducive to repeatedly testing the same sample multiple times, has good reusability, and the low dielectric constant filter membrane based on biological enzymes has good air permeability, which can enable the enzymes to fully contact with the gas, further improving the sensitivity of the sensor.

The invention relates to the technical field of auxiliary instruments for cesarean delivery, and particularly discloses a supine position corrector after cesarean delivery anesthesia, which comprises a fixing band, and further comprises an inflation support mechanism for inflating and supporting a patient after cesarean delivery anesthesia; the first air inflation bag and the second air inflation bag can be placed on an operation bed in advance, inflation is conducted after a patient is anesthetized, disinfection of the patient by medical staff is not affected, and when an operation starts, the first air inflation bag and the second air inflation bag can be rapidly deflated through the effect of the air inflation pump, the body position of the patient is recovered, and the operation is convenient. Normal operation of medical staff on a patient is not affected, meanwhile, use of boosting medicine can be reduced, the first inflation bag and the second inflation bag are small in use size, the medical staff can place and take out the first inflation bag and the second inflation bag very conveniently, correspondingly, the medical staff can disinfect the surgical site of the patient conveniently, and the operation can be carried out smoothly; therefore, the operation efficiency of the medical staff on the patient is improved.

The utility model belongs to the technical field of vacuum crystallization furnace equipment, and particularly relates to a vacuum crystallization furnace which comprises a furnace body, a cover plate is arranged at the top of the furnace body, and a bottom plate of the furnace body and the cover plate are both communicated with a vacuum pipe and a plurality of backfilling pipes; the heating part is arranged between the bearing part and the bottom plate of the furnace body, and the heating part is suitable for emitting heat to heat and crystallize the battery piece; the vacuum pipes are arranged to vacuumize the cavity from the top and the bottom of the furnace body at the same time, the vacuumizing effect is uniform, and the efficiency is high; nitrogen is introduced through the backfilling pipe to supplement gas to the cavity from the top and the bottom of the furnace body at the same time, so that the air pressure of the cavity is stable, and the drying progress is accelerated; by arranging the heating part, the heating mode of the heating part can be infrared heating, the crystallization of the battery piece coated with liquid medicine can be efficiently realized by heating the surface of the battery, a special crystallization cavity does not need to be additionally arranged, the use volume of the cavity is reduced, and the cost is reduced.

The present invention discloses a heavy metal detection and removal device for industrial wastewater treatment, which relates to the technical field of wastewater treatment, and includes: a device body, which is used for manufacturing and protecting device parts; a belt filter assembly, which is located at the bottom of the device body; a heavy metal collection assembly, which is located at the top of the belt filter assembly and at the top of the device body; and a crushing assembly, which is located at one side of the belt filter assembly and at one side of the device body. In the present invention, the second motor is powered on and rotates, driving the magnetic belt to rotate, adsorbing and collecting heavy metals, and then the filter teeth rotate, and impurities are transmitted to the top of the crushing assembly due to the filter teeth. The asynchronous motor drives the crushing wheel to rotate, and cooperates with the crushing teeth to crush large particles of impurities and drop them into a waste collection box for collection. This device can effectively filter out impurities, facilitate the transportation and collection of heavy metals, and crush waste to reduce the volume of waste used.
