[0002] Coking phenol-cyanide sludge is mainly the sludge left after biochemical and deep treatment of coking wastewater. It is a hazardous waste in the form of refined (steamed) distillation residue. Phenol-cyanide sludge is often mixed with blended coal for coking to realize the resource utilization of hazardous waste and turn waste into treasure. However, due to the high water content of phenol-cyanide sludge itself, directly pouring it into the coal preparation silo for blending is very likely to cause silo bulging, seriously affecting production.

[0003] In view of the above technical problems, the utility model provides a coking coal belt conveyor and a coking phenol-cyanide sludge treatment device, which is used to solve the problem that directly pouring phenol-cyanide sludge into the coal preparation silo for coal mixing easily causes the coal preparation silo to bulge.

[0004] In order to achieve the above-mentioned purpose, the technical solution of the present utility model is as follows:

[0005] A coking phenol-cyanide sludge treatment device used in conjunction with a coking coal belt conveyor comprises a sludge storage bin and a screw feeder. The discharge port of the sludge storage bin is connected to the feed port of the screw feeder. The discharge port of the screw feeder is connected to a feed pipe, which is connected to a nozzle. The coking coal belt conveyor is arranged below the nozzle.

[0006] Preferably, a motor is installed on the rotating shaft of the screw feeder.

[0007] Preferably, a heat-insulating pipe is provided on the outer wall of the feed pipe.

[0010] Preferably, a second gate valve is installed on each of the feed branch pipes.

[0011] Preferably, a first gate valve is installed on the discharge port of the sludge storage silo.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. When the coking coal belt conveyor conveys coking coal, the phenolic cyanide sludge in the sludge storage bin is pushed by the screw feeder and sprayed out from the nozzle through the feeding pipe, falling onto the coking coal layer on the coking coal belt conveyor, forming a form of coal layer + phenolic cyanide sludge layer on the coking coal belt conveyor, avoiding directly pouring the phenolic cyanide sludge into the coal preparation silo for coal blending, thus causing the problem of coal bridging in the coal preparation silo;

[0014] 2. Driving the screw feeder by a motor saves time and effort;

[0015] 3. The heat preservation pipe can not only play a certain heat preservation role in winter, but also prevent foreign objects from knocking against the feeding pipe, causing damage to the feeding pipe and affecting the production efficiency;

[0016] 4. The electric tracing band provides heat for the feeding pipe in winter to avoid freezing and blocking of the feeding pipe in winter. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] To make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below in conjunction with the specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present utility model. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily obscuring the concepts of the present utility model.

[0023] A coking phenol-cyanide sludge treatment device for use in conjunction with a coking coal belt conveyor, comprising a sludge storage bin 1 and a screw feeder 2. The discharge port of the sludge storage bin 1 is connected to the feed port of the screw feeder 2. A conveying pipe 3 is connected to the discharge port of the screw feeder 2, and the conveying pipe 3 is connected to a spray head 4. The coking coal belt conveyor 5 is arranged below the spray head 4. When the coking coal belt conveyor 5 conveys coking coal, the phenol-cyanide sludge in the sludge storage bin 1 is ejected from the spray head 4 through the conveying pipe 3 under the push of the screw feeder 2 and falls onto the coking coal layer on the coking coal belt conveyor 5, forming a form of coal layer + phenol-cyanide sludge layer on the coking coal belt conveyor 5, avoiding directly pouring the phenol-cyanide sludge into the coal preparation silo for coal blending, thus causing the problem of coal bridging in the coal preparation silo.

[0024] A motor 6 is installed on the rotating shaft of the screw feeder 2, and the screw feeder 2 is driven by the motor 6, which is time-saving and labor-saving.

[0025] A heat preservation pipe 7 is sleeved on the outer wall of the conveying pipe 3. The heat preservation pipe 7 can not only play a certain heat preservation role in winter, but also prevent foreign objects from bumping into the conveying pipe 3, causing damage to the conveying pipe 3 and affecting the production efficiency.

[0026] An electric heating tape 8 is also wound around the outer wall of the conveying pipe 3. The electric heating tape 8 is located between the conveying pipe 3 and the heat preservation pipe 7. The electric heating tape 8 is connected to the power supply line through a power supply junction box, and the electric heating tape 8 provides heat for the conveying pipe 3 in winter to avoid freezing and blocking of the conveying pipe 3 in winter.

[0027] The conveying pipe 3 branches into several conveying branch pipes 9, and spray heads 4 are installed at the ends of the conveying branch pipes 9. According to the actual needs on site, the number of conveying branch pipes 9 is selected to convey the phenol-cyanide sludge.

[0028] Second gate valves 10 are installed on each of the conveying branch pipes 9. Through the second gate valves 10 on each of the conveying branch pipes 9, the feeding of the conveying pipe 3 can be controlled, and several conveying branch pipes 9 can be selected to work simultaneously or several for use and several in reserve.

[0029] A first gate valve 11 is installed at the discharge port of the sludge storage bin 1.

[0030] During use:

[0031] When the coking coal belt conveyor 5 conveys coking coal, the corresponding first sluice valve 11 and the second sluice valve 10 are opened. If it is in the cold season, the electric heating tape 8 is synchronously turned on. The phenolic cyanide sludge in the sludge storage bin 1 is pushed by the screw feeder 2 and sprayed from the nozzle 4 through the conveying pipe 3, falling onto the coking coal layer on the coking coal belt conveyor 5, forming a form of coal layer + phenolic cyanide sludge layer on the coking coal belt conveyor 5. During the transfer process of the coking coal belt conveyor 5, the transfer station and the crusher, it is mixed. After being mixed with the coking coal, the phenolic cyanide sludge enters the sludge storage bin 1 to wait for reblending for coking, achieving the purpose of resource treatment of hazardous waste. At the same time, it avoids directly pouring the phenolic cyanide sludge into the coal preparation silo for coal blending, thus causing the problem of coal bridging in the coal preparation silo.
