This utility model discloses a combined solid waste incineration and waste liquid incineration two-combustion chamber treatment device, including a base and a mixing mechanism. The mixing mechanism is set on the top of the base. The mixing mechanism includes a two-combustion chamber body, a solid waste flue gas inlet pipe, a waste liquid flue gas inlet pipe, a mixing hood, a spiral baffle plate, a fixing plate, an end plate, a rotating shaft A, and an adjusting plate. The two-combustion chamber body is set on the top of the base, and the solid waste flue gas inlet pipe and the waste liquid flue gas inlet pipe are respectively installed on both sides of the base surface. A mixing hood structure is provided on the top of the base. The two flue gases entering the base enter the mixing hood from both sides. During the transportation process inside the mixing hood, the spiral baffle plate is used to fully mix the two flue gases before they are discharged into the two-combustion chamber body for combustion. One set of two-combustion chambers is used to treat the flue gases discharged from two different types of waste, while ensuring uniform mixing of the flue gases, avoiding affecting the combustion quality and uniformity, greatly reducing system costs and reducing equipment space occupation.

The utility model discloses an asphalt compaction device, and relates to the technical field of asphalt pavement backfill compaction, the asphalt compaction device comprises a compaction frame, and also comprises a power vibration device, the lower end of the power vibration device is provided with a compaction block through a screw; the cleaning and scraping device comprises a cleaning and scraping piece, an electric telescopic rod, a transmission piece and a driving motor, the cleaning and scraping piece is hinged to the upper portion of one side of the transmission piece, the electric telescopic rod is hinged to the bottom of the cleaning and scraping piece and the lower portion of one side of the transmission piece, and the driving motor is installed on the compaction frame through a screw. The output end of the motor is connected with the transmission part; and the power supply device is fixedly arranged at the top of the compaction frame. The device is used for cleaning and scraping the backfill material at the sampling hole adhered to the bottom of the compaction block in the compaction process of the compaction block, so that the backfill material is prevented from being adhered to the bottom of the compaction disc, the subsequent beating compaction uniformity is prevented from being influenced, the compaction disc is prevented from being corroded, and the service life of the compaction disc is prevented from being influenced.

The utility model discloses an anti-waste horizontal mixer which comprises a main body, rollers are hinged to two sides of one end of the main body, a jacking structure is arranged on one side of the main body, and a supporting rod is hinged between the jacking structure and the main body. Through the arrangement of the jacking structure, the gear can be driven to rotate by rotating the handle on one side of the gear, then the lead screw can be driven to rotate in the fixed frame, and in the rotating process, the movable frame can be driven to move up and down on the sliding rails on the two sides in the fixed frame along with the sliding blocks; the movable frame can drive one side of the supporting rod to move up and down, and the other side of the supporting rod can support one side of the main body upwards or downwards, so that the main body can be driven to rotate along with the hinged position of the main body and the rolling wheel, and then the main body can be driven to be in an inclined state, and materials can slide downwards and can be discharged from a discharging port in one side of the bottom end of the main body. According to the device, all materials can be conveniently discharged, and the waste phenomenon is prevented.

The utility model belongs to sewage treatment technical field, specifically is a kind of reagent adding mixing device for sewage treatment, including machine body, the top of machine body is fixedly connected with anti-sediment component, the anti-sediment component includes output motor, rotating rod, stirring vane, cleaning plate, filter plate, screw and nut, and the output end of output motor is fixedly connected with rotating rod by coupling;The reagent adding mixing device for sewage treatment cooperates with anti-sediment component, to prevent the effect of reagent deposition, the rotation of rotating rod is driven by starting output motor, to drive the rotation of stirring vane, to facilitate the full mixing of reagent, to make reagent mix evenly as much as possible, the reagent deposited at bottom is cleaned by cleaning plate, under the action of filter plate, when cleaning plate cleans reagent at bottom, reagent accumulation on the outer wall of cleaning plate affects its mixing uniformity.

This invention relates to the field of filament drawing technology for 3D printing, and particularly to a filament drawing device for 3D printing, comprising: two fixed frames, each with a rotating shaft rotatably connected to it, and the two rotating shafts being connected by a transmission belt. This invention uses a receiving groove on an arc-shaped receiving section in the middle of the transmission belt to receive the filament, and during the receiving process, it moves the filament. The rotation of the transmission belt and the straightening roller causes the receiving groove to engage with an annular groove to correct the roundness of the filament. Simultaneously, the filament is always supported by the receiving groove, preventing it from being suspended in the air during movement and thus deforming due to gravity. This improves the roundness and uniformity of the filament, avoiding the filament getting stuck on the print nozzle during 3D printing due to low uniformity, and improving the smoothness of filament use.
