Description

Technical Field

[0001] This utility model relates to the field of tailings production pipeline transportation technology, and in particular to a slag-slugging drum device at the front end of a diaphragm pump station. Background Technology

[0002] A diaphragm pump station is a fluid transport system with a diaphragm pump as its core equipment, primarily used for transporting various media. The diaphragm pump changes the pump chamber volume through the reciprocating motion of the diaphragm, achieving liquid intake and discharge. Typically, the pump station is designed with a self-cleaning filter tank for filtering impurities at the front end of the diaphragm pump. Due to complex operating conditions and large volumes of impurities, the filter tank system frequently activates its self-cleaning function, often resulting in overheating and burnout of the filter tank's agitator motor, and rapid wear of the electric drain valve, requiring frequent valve replacements. If the filter tank malfunctions and impurities cannot be discharged in time, it will cause significant damage to the diaphragm pump, leading to a complete system shutdown with potentially disastrous consequences.

[0003] Existing diaphragm pump sewage discharge equipment has poor sludge separation effect and low efficiency. The required equipment connection is unstable, requiring real-time inspection and maintenance. The equipment inspection cycle is frequent, the maintenance workload is large, and it cannot guarantee the stable operation of the sludge separation equipment. This poses a great challenge to the operation of downstream diaphragm pumps and affects subsequent production. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this utility model provides a front-end slag-slugging drum device for diaphragm pump stations. The slag-slugging drum is connected to a ore collection box and is arranged at an incline. A drum screen is installed on the outer wall of the drum. The slag and slurry are separated in the first stage by gravity through the rotation of the slag-slugging drum. The slurry after the first stage of slag and slurry separation enters the slurry separation mechanism and undergoes secondary slurry separation through a slurry buffer grid plate arranged in a gradient and cross interval. The separated slurry can directly enter the agitator. This completely solves the technical problems of equipment operation such as frequent burnout of motors in the front-end slag separation and self-cleaning filter tank of the diaphragm pump, reduces the wear of the sewage valve, and ensures stable operation of the equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A slag-separating roller device at the front end of a diaphragm pump station includes a ore collection box, a slag-separating roller, and a slurry separation mechanism. The ore collection box is connected to a slurry inlet pipe. A slag-separating feed pipe is installed at the bottom of the ore collection box, and the end of the slag-separating feed pipe is connected to the slag-separating roller. The slag-separating roller is inclined and has a roller screen on its outer wall. A slag-water separation screen is installed at the slag discharge port at the tail end of the slag-separating roller. The slag after slag-water separation enters the slag box, and the slurry is discharged into the slag-water discharge pipe. The slurry separation mechanism is inclined and installed on the slag-separating main platform. Rollers are installed at both ends of the slurry separation mechanism, and the slag-separating roller is installed between the rollers. A slurry discharge port is installed at the tail end of the slurry separation mechanism. The bottom of the slurry separation mechanism is gradient, and slurry buffer grids are arranged at cross intervals. Filter screens are installed on the slurry buffer grids.

[0007] Furthermore, a rubber buffer connector is provided at the bottom of the slag-straining drum, and the rubber buffer connector is connected to the motor reducer.

[0008] Furthermore, a rubber seal is provided between the slag-separating roller and the slag-separating feeding pipe.

[0009] Furthermore, the slag water drainage pipe is connected in parallel to the slurry discharge port.

[0010] Furthermore, the discharge port is connected to a mixer.

[0011] Furthermore, the agitator is located below the slag-straining main platform.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1) The primary slurry separation of the slurry separator drum and the secondary slurry separation of the slurry separation mechanism are carried out simultaneously, saving the connection process of the two slurry separations. There is no unnecessary equipment connection, good synchronization, high slurry separation efficiency, short slurry separation time, good slurry isolation effect, less clogging of diaphragm pump, less workload of downstream diaphragm pump, and good diaphragm pump operation effect.

[0014] 2) The device has fewer connection structures and less impact on the amount of slag discharged in the slurry. It completely solves the technical problems of equipment operation, such as the slag separation at the front end of the diaphragm pump and the frequent burnout of the motor of the self-cleaning filter tank. It reduces the wear of the sewage valve, ensures stable operation of the equipment, and realizes the use of one working and one standby for the diaphragm roller and the filter tank, ensuring 24-hour operation of the diaphragm pump station.

[0015] 3) The slurry separation roller and slurry separation mechanism are set at the top of the slurry separation main platform, and the slurry agitator is set at the bottom of the slurry separation main platform. The slurry separated by slurry is directly connected to the agitator. The device has a compact structure, simple connection, no need for real-time inspection and maintenance, extended equipment maintenance cycle, small maintenance workload, and low labor intensity.

[0022] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings:

[0023] like Figures 1-5 As shown, the working principle of a slag-separating roller device at the front end of a diaphragm pump station is as follows: The slag slurry is received by the ore collection box 2 and buffered. After settling in the ore collection box 2, the slag slurry is fed into the slag-separating roller 4. The slag slurry is separated once by gravity through the rotation of the slag-separating roller 4. The slag slurry after the first separation leaks out from the roller screen 4-1 on the outer wall of the slag-separating roller 4 and falls into the slag separation mechanism 5 below the slag-separating roller 4. The slurry water is discharged through the inclined surface at the bottom of the slag separation mechanism 5. During the discharge process, it is buffered and blocked by the slurry buffer grid 5-2. A filter screen is set on the slurry buffer grid 5-2 to filter out the fine slag particles in the slurry, thus performing a second slag separation. The slurry discharged from the tail of the slag-separating roller 4 is filtered by the slag-water separation net to remove large slag particles. The slurry water is then mixed with the slurry water in the slurry discharge port 5-4 at the tail of the slurry separation mechanism 5 through the slag-water discharge pipe 9 and then directly fed into the agitator 11.

[0024] like Figures 1-5As shown, a slag-separating roller device at the front end of a diaphragm pump station includes a ore collection box 2, a slag-separating roller 4, and a slurry separation mechanism 5. The ore collection box 2 is connected to a slurry inlet pipe 1. After the slurry enters the ore collection box 2 and settles, it enters the slag-separating roller 4 for primary slag separation. A slag-separating feed pipe 3 is installed at the lower part of the ore collection box 2. After the slurry in the ore collection box 2 settles, large pieces of slag fall to the bottom of the ore collection box 2. After settling, the slurry with the large pieces of slag removed enters the slag-separating roller 4. The end of the slag-separating feed pipe 3 is connected to the slag-separating roller 4. A rubber buffer joint 4-3 is installed at the bottom of the slag drum 4, which is connected to a motor reducer 4-2. The motor reducer 4-2 is mounted on a motor base 4-4 and drives the drum screen 4-1 to rotate. The bottom ends of the slag drum 4 are supported by four sets of roller assemblies 5-3, which support the drum screen 4-1 in pairs. The rolling friction reduces the friction of the drum screen 4-1 during rotation, improving the stability and flexibility of the rotational transmission. The slag drum 4 is arranged at a 30° angle, and the drum screen 4-1 is installed on the outer wall of the slag drum 4. The slag slurry is separated once by gravity through the rotation of the slag drum 4. A slag-water separation net 7 is installed at the slag outlet 6 at the tail end of the slag-separating roller 4. The waste slag after slag-water separation enters the slag box 8, and the slurry is discharged into the slag-water drainage pipe 9. The slag-water separation net 7 further separates the remaining slag particles and slurry after the first separation. The slag box 8 is welded to the lower end of the slag-water separation net 7 to collect and store the waste slag. A DN200 pipeline is connected to the bottom of the slag box 8 to discharge the waste slag to the slag yard. A loader regularly cleans the waste slag. The slurry separation mechanism 5 is inclinedly installed on the slag-separating main platform 10. The slurry tank 5-1 of the slurry separation mechanism 5 is semi-enclosed around the bottom of the slag-separating roller 4. The slurry separation mechanism 5 is equipped with roller assemblies 5-3 at both ends, and the slag-separating roller 4 is installed between the roller assemblies 5-3. The roller assemblies 5-3 support the slag-separating roller, so that the slurry after the first separation falls smoothly into the slurry separation mechanism 5. A slurry discharge port 5-4 is provided at the tail end of the slurry separation mechanism 5. The bottom of the slurry separation mechanism 5 is gradient, and slurry buffer grids 5 are arranged at cross intervals. -2, The slurry buffer grid 5-2 is equipped with a filter screen, and the density of the filter screen increases as it approaches the slurry outlet 5-4. The slurry is separated into slag and slurry for the second time through the filter screen of the slurry buffer grid 5-2, which improves the slag separation effect of the slurry, reduces the slag particles in the slurry, solves the problem of slag particles damaging the diaphragm pump, reduces the workload of the diaphragm pump, and improves the operation of the diaphragm pump. The slurry buffer grid 5-2, which is arranged in a gradient and cross-interval manner, can not only separate the slag and slurry for the second time, but also prevent the tailings slurry from being directly discharged from the slag outlet 6 at the tail end of the slag separation roller 4 under the driving force of falling impact.

[0025] like Figure 2 As shown, furthermore, a rubber plug 2-1 is provided between the slag-separating roller 4 and the slag-separating feeding pipe 3 to prevent slag slurry from flowing out of the inlet of the slag-separating roller 4.

[0026] like Figure 1 As shown, further, the slag water drainage pipe 9 is connected in parallel to the slurry discharge port 5-4, and the slurry discharge port 5-4 is connected to the agitator 11. The agitator 11 is set below the slag separation main platform 10. The slurry after slag separation directly enters the agitator 11. The ore collection box support 10-2 and the slag separation roller support 10-3 are set on the main beam platform 10-1 of the slag separation main platform 10. The ore collection box 2, the slag separation roller 4 and the slag separation mechanism 5 are set above the slag separation main platform 10. The agitator 11 is set below the slag separation main platform 10. The slag separation and agitation are tightly connected.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and concept of the present utility model, should be included within the protection scope of the present utility model.
