This invention relates to the field of high-purity aluminum purification technology and discloses a high-purity aluminum vacuum purification device, including a support and a crucible fixedly connected to the top of the support. The crucible has several release grooves on its bottom circumference, a heating assembly is arranged around the crucible, a sealing cover is movably hinged to the top of the crucible, an air extraction port is provided at the upper end of the sealing cover, a locking ring is rotatably connected to the bottom of the sealing cover, and several locking grooves are arranged around the outer circumference of the locking ring. Several locking blocks arranged in a circumferential array are fixedly connected to the inner wall of the top of the crucible. This invention, through the automatic closing and locking assembly of the sealing cover, can control the uniform pressure applied to all parts of the sealing cover edge, resulting in rapid and reliable sealing operation, thereby enhancing sealing performance and improving purification quality. Furthermore, without affecting purification quality, it greatly increases the purification rate of high-purity aluminum, achieving uniform cooling of the aluminum ingot from the core to the outer wall, ensuring the stability of directional crystallization.

This invention discloses a high-temperature, high-dust-content flue gas purification device, relating to the field of flue gas purification technology. The device includes an adjustable purification structure comprising multiple ceramic filter elements. SCR catalyst components are coated on the surface of each ceramic filter element. A swirling ammonia injection grille is installed at the inlet end of each ceramic filter element. An attitude adjustment mechanism is connected to the purification structure. A PLC control system is electrically connected to the attitude adjustment mechanism, which controls the ceramic filter elements of the purification structure to switch between vertical, inclined, and parallel settings. In the vertical setting, flue gas passes through the filter element in a straight line from top to bottom or bottom to top. In the inclined setting, flue gas passes through obliquely, forming a "Z"-shaped path. In the horizontal setting, flue gas flows laterally through the filter element, and particulate matter is deposited downwards under gravity. This invention solves the problem of low removal efficiency of fine particulate matter, achieving highly efficient purification of high-temperature, high-dust-content flue gas, and is particularly suitable for treating high-emission flue gas under complex operating conditions.

An adjustable circulating fluidized bed boiler for incinerating pyrolysis residues is disclosed. This invention addresses the problems of unstable bed temperature and pressure, and equipment shutdown due to excessive parameters, that commonly occur in existing circulating fluidized beds when incinerating different pyrolysis waste residues. The invention comprises a fluidized bed boiler body (6), a sub-bed air chamber (2), multiple dispersion pipes (5), and multiple high-temperature resistant gate valves (32). The sub-bed air chamber (2) is installed at the lower part of the fluidized bed boiler body (6). The upper parts of the multiple dispersion pipes (5) are connected to the fluidized bed boiler body (6) in a ring array, and the lower parts of the multiple dispersion pipes (5) are connected to the sub-bed air chamber (2). Each dispersion pipe (5) is equipped with a high-temperature resistant gate valve (32). The opening degree of the high-temperature resistant gate valve (32) is remotely adjusted through a control program to achieve bed pressure regulation of the fluidized bed without changing the combustion load and fluidizing air volume. This invention is used for the incineration of pyrolysis residues.

The invention discloses a device and a process for improving the alkalization degree of polyaluminum chloride and the content of solid aluminum oxide, and relates to the technical field of chemical equipment, a mounting cylinder, a dispersion mechanism and a plurality of ion exchange mechanisms are arranged, so that multi-stage and alternate ion exchange and forced redispersion treatment of a high-viscosity polyaluminum chloride salt raw solution are realized, and the high-viscosity polyaluminum chloride salt is obtained. The phenomena of dead zone, bias flow and channeling caused by high viscosity characteristic in the traditional single-stage or simple multi-stage fixed bed are effectively inhibited, the flow field of the solution in each ion exchange layer tends to be uniform, and the actual effective contact time is closer to the theoretical retention time, so that the chloride ion removal rate and the alkalization degree amplification are obviously improved, and the quality of the product is improved. Meanwhile, the stability of the content of solid aluminum oxide and the quality consistency between batches of products are improved, and finally the overall quality stability and preparation efficiency of the polyaluminum chloride salt product are improved.

This invention proposes a cable sheath lead sealing and welding fixing mold, specifically relating to cable processing equipment. The cable sheath lead sealing and welding fixing mold includes a worktable and a lower mold fixedly connected to the worktable. Multiple limiting rods are fixedly connected to the lower mold, and an upper mold is slidably connected to the multiple limiting rods. A lead injection hole is opened in the middle of the upper mold. Both ends of the lower and upper molds are provided with clamping parts. Each clamping part includes a first arc-shaped clamping plate rotatably connected to the lower mold and a second arc-shaped clamping plate rotatably connected to the upper mold. The cable sheath lead sealing and welding fixing mold provided by this invention uses a drive unit to rotate the cable held by the clamping parts within the mold. Centrifugal force effectively removes air bubbles and impurities from the molten lead, making the temperature and flow fields of the molten lead more uniform, thereby reducing defects such as porosity and shrinkage, and enhancing the bonding effect between the lead layer and the cable sheath.
