This utility model relates to a gas cooling and scrubbing tower, belonging to the field of gas purification technology. It includes a tower body, an air inlet, an air outlet, and a liquid outlet, located on the side, top, and bottom of the tower body, respectively. Between the air inlet and outlet within the tower body's internal cavity, a first spray device, a uniform flow water curtain layer, and a second spray device are sequentially arranged from bottom to top. The uniform flow water curtain layer includes a uniform flow water curtain baffle, and a water curtain regulating component is arranged above the baffle. This utility model utilizes the uniform flow water curtain baffle and the second spray device to repeatedly deflect, mix, cool, and scrub dust-laden gas, solving the problems of gas flow deviation, poor cooling and scrubbing effects in existing hollow cooling and scrubbing towers. It has the advantages of high scrubbing efficiency, low resistance, no clogging, simple structure, and easy maintenance.

This invention provides a grouting device and a construction method for cast-in-place piles, belonging to the technical field of grouting devices. The device includes an outer grouting pipe and an inner grouting pipe: the outer and inner grouting pipes are coaxially arranged, with a pre-embedded part at one end of the outer grouting pipe, including a pipe head, a protective pipe, and a breakable component; the inner grouting pipe has multiple sets of second grout outlets at one end near the pre-embedded part, the pipe head is installed on the inner grouting pipe, and the two ends of the protective pipe are respectively sleeved on the inner grouting pipe and the pipe head, covering the second grout outlets for sealing and preventing blockage during pre-embedding; a first grouting cavity is formed between the outer and inner grouting pipes, and a second grouting cavity is formed inside the inner grouting pipe; multiple sets of first grout outlets are opened on the side wall of the outer grouting pipe; a grouting end cap is installed on the outer grouting pipe, with a detachable first plug and a second plug inside the grouting end cap, and a grouting port is opened on the grouting end cap; this improves the stability and reliability of the device during grouting construction and avoids rework due to channel blockage.

The invention relates to the technical field of grinding machines, in particular to an auxiliary feeding type grinding machine which comprises a main body part, a grinding part used for grinding materials is installed in the longitudinal middle of the main body part, a discharging part is connected to the lower portion of the grinding part, a waste collecting part is installed on the main body part, and a feeding part is arranged between the top of the main body part and the grinding part. The feeding part is driven by the grinding part to conduct stable and continuous feeding, and the waste collecting part is connected with the feeding part, the grinding part and the discharging part. Therefore, blockage during feeding of materials can be effectively prevented, accumulation and clamping stagnation of the materials are effectively avoided, the shutdown cleaning frequency of equipment is reduced, continuous and stable operation of the equipment is guaranteed, the grinding efficiency can be guaranteed, the materials can be pretreated and crushed during feeding, the grinding stroke can be shortened, the grinding load is reduced, and the grinding yield in unit time is increased.
