The invention discloses a cell heat shrink film packaging machine which comprises a heat shrink film conveying mechanism, and the heat shrink film conveying mechanism comprises a first supporting plate (1), a partition plate (2) and a stepping motor (3), wherein an upper compression roller (4) and a lower compression roller (5) are rotatably matched on the first supporting plate (1), an upper gear (6) is fixed at the outer end of the upper compression roller (4), a lower gear (7) is fixed at the outer end of the lower compression roller (5), the upper gear (6) and the lower gear (7) are mutually meshed, and one of the two gears is a gear driven by the stepping motor (3); and two upper rolling wheels are rotatably matched to the upper end face of the partition plate (2), two lower rolling wheels are rotatably matched to the lower end face of the partition plate (2), the two lower rolling wheels under the lower end face of the partition plate (2) are abutted against the circumferential face of the lower compression roller (5), and the circumferential face of the upper compression roller (4) is abutted against the two upper rolling wheels on the upper end face of the partition plate (2). With the cell heat shrink film packaging machine, different lengths and different quantities of various shrink cells can be packed.

The invention provides a thermal-cycle continuous pyrolysis-gasification comprehensive device for coal gangues. The thermal-cycle continuous pyrolysis-gasification comprehensive device for coal gangues comprises a coal gangue pyrolysis-gasification furnace, a raw coke oven gas condensing device, a raw coke oven gas recycling and purifying device, a furnace coal gangue heat waste gas humidifying and dehydrating device and tail gas water-spraying purifier, wherein a raw coke oven gas guide-out device of the coal gangue pyrolysis-gasification furnace is communicated with the raw coke oven gas condensing device; and the raw coke oven gas condensing device is communicated with the raw coke oven gas recycling and purifying device. The purified raw coke oven gas is combusted; the combusted waste gas is fed to the furnace coal gangue heat waste gas humidifying and dehydrating device; and the dehydrated waste gas is exhausted through the tail gas water-spraying purifier. Besides, the combusted waste gas is fed to an active coke regenerator of the raw coke oven gas recycling and purifying device; and the waste gas regenerated by the active coke regenerator is fed to a waste gas heat exchange dehydrator or the tail gas water-spraying purifier. The thermal-cycle continuous pyrolysis-gasification comprehensive device for the coal gangues is prominent in environmental protection benefit by utilizing the pyrolysis-gasification of the coal gangues and not consuming extra energy resources, and is considerable in economic value.

The invention discloses a device and a method for improving ammonium sulfate crystal quality. In the device, a main body consists of a size cooling kettle which is connected with a process water feeding pipe; a stirrer which is extended downward into size is arranged in the size cooling kettle; a cooling interlayer is arranged outside the size cooling kettle; the upper part and the lower part of the cooling interlayer are provided with a cooling water inlet and a cooling water outlet respectively; the cooling water inlet is connected with a process water branch pipe which is separated from the process water feeding pipe; the cooling water outlet is connected with the process water feeding pipe through a cooling water outlet pipe; and the connection part of the cooling water outlet pipe and the process water feeding pipe is close to a water inlet of a process water box. A bypass is separated from the process water feeding pipe and size enters the process water box through the cooling interlayer outside the size cooling kettle; and by reducing the size temperature, the contour dimensions of crystals are increased and dehydration is facilitated. The device has a simple structure, is convenient to install, obviously improve the ammonium sulfate crystal quality, and can be widely applied to crystal treatment of thiamine in desulfuration by an ammonia method, and energy consumption of a system is not needed to be increased.
