Description

Technical Field

[0001] The utility model relates to coarse water run-off prevention and blockage prevention, in particular to a lower chute prevention and blockage detection device for a peat water centrifuge. Background Art

[0002] With the continuous improvement of mechanized mining and the amount of coal washed, the pulverized coal content in the washing process has also increased, placing an increased load on the coal preparation plant's slurry water system. With the increase in pulverized coal, utilizing a coarse coal slurry recovery system to reduce the load on the slurry water system is a key step in ensuring the stable operation of the slurry water system. Therefore, ensuring the stable operation of the coarse coal slurry recovery system and preventing system coarse coal slurry leakage has been a topic of research and study for coal preparation workers for many years. If system coarse coal slurry leakage is not promptly addressed, it will not only affect the normal production of the coal preparation plant, but may also cause environmental incidents such as coal slurry overflow, resulting in huge economic losses to the enterprise.

[0003] The coarse run-off and anti-blocking device mainly consists of: cyclone outlet blockage detection, centrifuge coarse run-off detection, vibrating screen lower funnel anti-blocking detection, centrifuge lower chute anti-blocking detection.

[0004] The peat water enters the centrifuge for dehydration. The centrifuge liquid contains media and cannot enter the coal slime water system directly. It needs to be magnetically separated by a magnetic separator before entering the coal slime water system. The coal slime centrifuge is a key dehydration equipment in the coarse coal slime recovery system. If the screen blue bars wear, the screen gaps become larger, and the screen bars break, coarse particles will enter the downstream coal slime water system, causing coarse run-off.

[0005] During the coarse inspection of the centrifuge, workers are required to manually hold the filter to collect the particles and then weigh them, which takes up a long time of workers, results in untimely inspection, easily damages the equipment, and is inefficient. Utility Model Content

[0006] In order to solve the defects of the above-mentioned prior art, the utility model provides a peat water centrifuge lower chute anti-blocking detection device. The utility model utilizes a cylinder and a movable frame for timing detection, and the detection is timely and efficient.

[0007] To achieve the above technical objectives, the present invention adopts the following technical solutions: a peat water centrifuge lower chute anti-blocking detection device, comprising an upper pipe, a track assembly, a movable frame, a guide slope, and a weighing platform, wherein the upper end of the upper pipe is connected to the water outlet of the peat water centrifuge, and the track assembly is arranged below the lower end opening; the movable frame is arranged on the track assembly and can move along the track so that the movable frame is located below the upper pipe outlet, or leaves the lower end of the upper pipe outlet and moves to above the guide slope, and the guide slope is located below the track assembly; the lower end plate of the movable frame is an open structure to release particulate matter onto the guide slope below; the weighing platform is located at the end of the guide slope.

[0008] The track assembly is a double-track structure, and a baffle is fixed at one end of the double track and a mounting plate is fixed at the other end. The baffle and the mounting plate are respectively located on both sides of the upper pipe, and the mounting plate is located above the guide slope; the mounting plate is installed with a cylinder, and the cylinder drives the movable frame.

[0009] The double track is further fixed with a first support plate and a second support plate. The first support plate is located at the baffle, and the second support plate is located on the other side of the upper pipe. The first support plate and the second support plate can support the moving frame.

[0010] The movable frame has an opening at the top and an end plate at the bottom. The end plate is a filter structure. One side of the end plate close to the baffle is hinged to the movable frame body, and the other three sides are free. When the movable frame moves toward the baffle, the three free sides of the end plate are closed with the movable frame body under the support of the second support plate. When the movable frame moves toward the cylinder and when the movable frame completely leaves the second support plate, the three free sides of the end plate lose the support of the second support plate and fall downward, causing the end plate to open.

[0011] The front end of the upper surface of the guide slope is provided with a water absorbing layer, and the tail end of the upper surface of the guide slope is a rolling slope.

[0012] A weighing frame is placed on the weighing platform.

[0013] It also includes a lower pipe, wherein the upper end of the lower pipe is provided with a funnel, the inlet diameter of the funnel is larger than the diameter of the upper pipe, and the upper surface of the funnel is close to the double track.

[0014] In summary, the present invention has achieved the following technical effects:

[0015] The utility model provides a movable frame below the upper pipe to catch particulate matter. The end plate of the movable frame adopts a filter screen. The movable frame is pulled out regularly to open the movable frame so that the particulate matter falls on the slope below and falls on the weighing platform after rolling and dehydration. The automatic detection is high in efficiency and precision, and the coarse matter can be found in time, which reduces a lot of workload in processing the coarse matter, plays a good preventive role, and reduces serious economic losses.

[0025] Example:

[0026] From the current technology, roughness cannot be eliminated. In order to avoid the accident from escalating and prevent larger production accidents, some preventive measures need to be taken to detect and deal with roughness in time and carry out effective prevention.

[0027] Figure 1 This is a schematic diagram of the initial state of the anti-blocking detection device for the lower chute of a peat water centrifuge. Figure 2 yes Figure 1 A top view of Figure 3 yes Figure 1 Schematic diagram of weighing status.

[0028] It includes an upper pipe 1, a track assembly 4, a moving frame 3, a guide slope 9, and a weighing platform 11. The upper end of the upper pipe 1 is connected to the water outlet of the peat water centrifuge, and the track assembly 4 is arranged below the lower end opening. The moving frame 3 is arranged on the track assembly 4 and can move along the track so that the moving frame 3 is located below the outlet of the upper pipe 1, or leaves the bottom of the upper pipe 1 outlet and moves to the top of the guide slope 9, and the guide slope 9 is located below the track assembly 4; the lower end plate 31 of the moving frame 3 is an open structure to release particulate matter to the guide slope 9 below; the weighing platform 11 is located at the end of the guide slope 9.

[0029] Specifically, such as Figure 2 As shown, the track assembly 4 is a dual-track structure, with a baffle 6 fixed to one end and a mounting plate 41 fixed to the other. The baffle 6 and mounting plate 41 are located on either side of the upper pipe 1, and the mounting plate 41 is located above the guide ramp 9. The mounting plate 41 is mounted with a cylinder 5, which drives the movable frame 3. The dual-track is long, exceeding the length of the two movable frames, allowing the movable frames to move back and forth. The dual-track is mounted on a frame (not shown). The cylinder 5 drives the movable frame to move.

[0030] The double track is also fixed with a first support plate 7 and a second support plate 8. The first support plate 7 is located at the baffle 6, and the second support plate 8 is located on the other side of the upper pipe 1. The first support plate 7 and the second support plate 8 can support the moving frame 3.

[0031] The movable frame 3 has an opening at the top and an end plate 31 at the bottom. The width of the end plate 31 is the inner diameter of the double track and can be opened or closed. The end plate 31 is a filter structure that can allow peat water to flow downward and catch particulate matter. The side of the end plate 31 close to the baffle 6 is hinged to the main body of the movable frame 3, and the other three sides are free. When the movable frame 3 moves toward the baffle 6, the three free sides of the end plate 31 are merged with the main body of the movable frame 3 under the support of the second support plate 8. When the movable frame 3 moves toward the cylinder 5 and when the movable frame 3 completely leaves the second support plate 8, the three free sides of the end plate 31 lose the support of the second support plate 8 and fall downward, causing the end plate 31 to open.

[0032] During the movement of the moving frame with the cylinder 5, the second support plate 8 plays the role of closing or opening the end plate 31, thereby realizing an unattended function.

[0033] The front end of the upper surface of the guide ramp 9 is provided with a water-absorbing layer 91, and the rear end of the upper surface of the guide ramp 9 is provided with a rolling slope 92. The water-absorbing layer 91 is made of a sponge or other absorbent material to absorb moisture from the particles. The rolling slope 92 is not provided with a water-absorbing layer to prevent moisture from dripping onto the weighing platform and affecting the weight.

[0034] A weighing frame 10 is placed on the weighing platform 11. The weighing frame 10 is cleaned regularly, which can be done manually or automatically by turning the cylinder over, and the details will not be repeated here.

[0035] The lower pipe 2 is further provided with a funnel 21 at its upper end, the funnel 21 having an inlet diameter greater than that of the upper pipe 1 and an upper surface close to the double tracks. The funnel 21 can catch all the peat water discharged from the upper pipe 1 to prevent it from leaking out.

[0036] Working principle:

[0037] The initial state is Figure 1 As shown, the moving frame collects the particles;

[0038] The cylinder sets a time interval, and the cylinder contracts, pulling the moving frame 3 to the upper position of the guide slope 9. During the movement, the end plate 31 gradually loses the support force of the second support plate 8, and the end plate 31 falls. The particles on the end plate 31 fall on the guide slope 9, absorb water on the water absorption layer, roll to the rolling slope 92, and fall into the weighing frame 10 below. The weighing platform 11 is used to: if the weight measured is greater than the set threshold, a signal is sent to the PLC, and the PLC signal is used to send an alarm to the centralized control. This device prevents the serious consequences of coal slurry overflow and serious economic losses.

[0039] After the cylinder contracts for a certain period of time, it extends again to push the moving frame back to its original position.

[0040] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are within the scope of the technical solution of the present invention.
