The utility model relates to high -purity antimony processing equipment technical field, concretely is a kind of high -purity antimony vacuum distillation pipe device, including bushing, for guiding antimony steam to enter into tray inside;Tray, tray is provided with gas guide hole, grating, for condensing receiving material;Conical tube, conical tube is conical, for low boiling point impurity and a small amount of antimony condensation.The high -purity antimony vacuum distillation pipe device in this device, by setting 5-10 trays from top to bottom in bushing, and the gas guide hole of adjacent two layers of trays is cross arrangement, make steam present S type route movement.This design greatly increases the movement path and contact area of antimony steam in device, effectively controls steam flow state, avoids the phenomenon that antimony steam appears uneven distribution, over-condensation or condensation is not sufficient in condensation process, significantly improves the condensation efficiency and crystallization quality of high -purity antimony.

The utility model relates to an anti-overflow radial flow sedimentation tank and belongs to the technical field of radial flow sedimentation tanks. Comprising a radial flow sedimentation tank body and a standby overflow pipe, the front side of the radial flow sedimentation tank body is fixedly connected with an overflow water outlet pipe, the front end of the overflow water outlet pipe is connected with a three-way pipe through a bolt flange, the left side of the three-way pipe is connected with a buried pipe through a bolt flange, and the right side of the three-way pipe is connected with the standby overflow pipe through a bolt flange; the front side of the standby overflow pipe is fixedly connected with a flow guide pipe. Through the arrangement of the standby overflow pipe, when the flow is reduced due to scaling in the underground pipe, the standby overflow pipe can still keep the drainage function, so that the overflow condition of the radial flow sedimentation tank body is effectively prevented; through the arrangement of the filter pipe, the collecting cylinder in the filter pipe can intercept large-particle impurities or dirt in the water body, so that the water outlet pipe is prevented from being influenced by a scaling phenomenon after long-time drainage work, and the drainage problem caused by dirt accumulation is reduced.

The utility model discloses a cooking fume collecting hood of a cooking fume purifier in catering industry, which comprises a lower fume hood, an oil collecting tank fixedly arranged on the side surface of the lower fume hood, an oil collecting inclined plate fixedly arranged on the lower fume hood, a side plate fixedly arranged on the side surface of the oil collecting tank, an oil discharging valve fixedly arranged on the side surface of the side plate, and a cleaning carriage arranged inside the oil collecting tank. A push-pull rod is fixedly arranged on the side face of the cleaning carriage, an oil inlet hole is formed in one end of the inner side of the oil collecting tank, and a control panel is fixedly arranged on one side of the lower smoke hood. According to the utility model, through the design of the oil collecting inclined plate, grease in oil fume can smoothly drop and be collected into the oil collecting tank, subsequent grease treatment is facilitated, meanwhile, through the cleaning carriage and the replaceable sponge brush plate, grease on the inner wall of the oil collecting tank can be conveniently scraped off, the cleaning process is simplified, and the cleaning efficiency is improved.

The utility model relates to the field of coking waste gas treatment, and discloses a coking waste gas treatment device which comprises an activated carbon box, a transmission mechanism, a drawer frame and an activated carbon bearing frame, a transverse insertion opening is formed in the activated carbon box, the drawer frame is installed in the insertion opening in a drawing mode, a plurality of rotatable activated carbon bearing frames are arranged in the drawer frame side by side in the transverse direction of the drawer frame, and a transmission mechanism is arranged in the activated carbon box. When the drawer frame is inserted into the insertion opening, the transmission mechanism is driven to enable the activated carbon bearing frame to rotate from the vertically upward direction to the side direction of the drawer frame, and when the drawer frame is pulled out of the insertion opening, the transmission mechanism is driven to enable the activated carbon bearing frame to rotate from the side direction of the drawer frame to the vertically upward direction; according to the utility model, the purification treatment effect can be effectively improved, and the mode is only improved design on the basis of the original transverse drawer box and the activated carbon box with the transverse insertion opening, so that the activated carbon box and the drawer box do not need to be redesigned and replaced, the work amount is reduced, and the cost can be greatly saved.

The invention discloses a filtrate floating object separation device and kitchen waste treatment equipment and method, solves the problem that a separator is easily blocked by floating objects in the prior art, and has the beneficial effect of effectively and efficiently removing the floating objects in filtrate, and the specific scheme is as follows: the filtrate floating object separation device comprises a shell, a partition plate is arranged in the shell, one side of the partition plate is provided with a filtrate tank, the other side of the partition plate is provided with a separation liquid tank, the top end of the partition plate is lower than the top of the shell, multiple clamping grooves are formed in the top end of the partition plate, and rolling brushes are arranged at the positions, lower than the clamping grooves, in the separation liquid tank of the shell and can rotate relative to the shell. A conveying component is arranged at the position, lower than the rolling brush, of the shell in the separation liquid tank, a scraping plate is arranged between the conveying component and the rolling brush, one end of the scraping plate makes contact with the rolling brush, and in the process that filtrate in the filtrate tank flows to the separation liquid tank through the clamping groove, floating objects in the filtrate fall on the rolling brush. In the rotating process of the rolling brush, the floating objects enter the conveying component under the action of the scraper blade.

The invention discloses a screening and filtering device for waste drilling fluid in an oil field, and relates to the technical field of waste drilling fluid treatment. The device comprises a stirring cylinder, wherein a driving component is fixedly connected to the top of the stirring cylinder, a stirring blade is fixedly connected to the output shaft end of the driving component, the bottom end of the stirring blade is located inside the stirring cylinder, a liquid inlet bucket is fixedly connected to the top of the stirring cylinder, the liquid inlet bucket is communicated with the inside of the stirring cylinder, an auxiliary screening mechanism for intercepting large-grained impurities in the waste drilling fluid to prevent the stirring blade from being worn is arranged inside the liquid inlet bucket, the auxiliary screening mechanism comprises a fixed ring rotatably connected to the inner wall of an opening at the bottom of the liquid inlet bucket, a lifting rod is slidably connected through the inner wall of the fixed ring, and compared with the prior art, the clogging of the filter screen can be reduced, and the processing efficiency can be avoided. At the same time, frequent maintenance and replacement of the filter screen are not required, and the use cost is reduced, and large-grained impurities can be avoided from entering, rubbing against the stirring blade, and accelerating the wear thereof.
