The utility model discloses a gas treatment device after gas pressure protection and safety pressure relief of an excimer laser, which comprises a rupture disk device (1) with one end capable of being communicated with a resonant cavity of the excimer laser. The other end of the rupture disk device (1) is provided with a one-way safety valve (2) which can be jacked open by working gas leaked from the resonant cavity when a diaphragm (14) of the rupture disk device (1) is ruptured, and the one-way safety valve (2) is connected with an absorption device (3) which can purify the leaked working gas; and the absorption device (3) is provided with an exhaust port (4) capable of exhausting purified gas. According to the utility model, the structure is simple, external air can be prevented from flowing backwards into the excimer laser, the internal gas is kept pure, the discharged gas is absorbed and purified, so that the discharged gas can reach the emission standard, and the harm to workers and the environment is eliminated.

The utility model discloses a cable coating processing device. Relates to the technical field of cable processing, and adopts a base, a dedusting assembly and a drying assembly, the top end of the base is provided with a pay-off roller, and the top end of the base is provided with a take-up roller on one side of the pay-off roller. By arranging the dust removal assembly, before a cable body enters the wrapping machine body, the cable body firstly passes through the dust removal assembly, an air cylinder is started, and the air cylinder drives an adjusting rod to stretch out and draw back, so that a first cleaning brush is pushed to move up and down, and the first cleaning brush and a second cleaning brush are both precisely attached to the outer wall of the cable body; according to the coating device for cable processing, dust on the surface of a cable is cleaned, then a dust suction machine is started, dust in a dust removal box can be collected through a dust suction opening, and the problems that a traditional coating device for cable processing is poor in use effect, the cable is inconvenient to clean, and the coating effect is affected by the dust attached before the cable enters a coating machine are solved.

This invention discloses a channel equalization method for an SC-IFDMA system, comprising the following steps: transforming the received data of the SC-IFDMA system to the frequency domain; obtaining pilot symbols and data symbols according to the system frame structure; estimating the current signal-to-noise ratio (SNR) and current channel characteristics based on the pilot symbols to obtain estimated SNR and channel estimation parameters; calculating channel equalizer coefficients based on the estimated SNR and channel estimation parameters; passing the data symbols through the channel equalizer, setting the number of iterations, and iteratively equalizing the data symbols using the channel equalizer coefficients; transforming the equalized data symbols to the time domain and making a decision; determining whether the current number of iterations is the set number; if the set number is reached, outputting the current data symbol as the final iterative equalization result. The method disclosed in this invention improves equalization performance while keeping most of the processing in the frequency domain, reducing the complexity of signal processing.

This application discloses a molecular sieve pelletizing machine, relating to the field of pelletizing machines. The present invention provides a molecular sieve pelletizing machine, relating to the technical field of pelletizing machines. The molecular sieve pelletizing machine includes a base, a support frame on top of the base, and a rotating box rotatably connected to one side of the support frame. A rotary motor is located on one side of the support frame. In this application, raw materials are first added to the interior of the rotating box through a feeding port. Then, the rotary motor is started to rotate the rotating box. Next, a water pump box is started, causing water in the water pump box to be sprayed into the rotating box from a spray nozzle on a water spray pipe connected to the water pump box. A baffle is provided to prevent raw material powder agitated by the water spray from the spray nozzle, thus preventing this raw material powder from splashing everywhere and affecting the working environment. A cleaning device can be used to clean the bottom surface of the baffle and the inner wall of the rotating box to remove the wet raw material powder adhering to them, preventing wet powder residue from sticking to the inner wall of the rotating box and the bottom surface of the baffle and being difficult to clean.
