Description

Technical Field

[0001] This utility model relates to the field of building materials machinery technology, specifically to a feed pipe structure for a roller press V-type classifier. Background Technology

[0002] A V-type classifier is a static grading device mainly used in conjunction with a roller press. It can break up the cake material produced by the roller press and separate out the qualified fine powder. The main function of the feed pipe structure of the V-type classifier is to ensure that the material can enter the V-type classifier evenly and stably, avoiding the decrease in classification efficiency or equipment failure caused by material concentration or blockage.

[0003] The feed pipe structure of some existing roller press V-type air classifiers has obvious defects. First, the angle of the air guide plate is fixed, and it cannot be adjusted according to the material characteristics and air volume requirements. This leads to uneven airflow distribution in the channel and is prone to "air short circuit" phenomenon - the air velocity in some areas is too high while the air velocity in other areas is insufficient (usually below 6m / s), which seriously affects the sorting accuracy and efficiency of the V-type air classifier. Second, the air inlet and the side wall near the air inlet of the V-type air classifier are prone to material accumulation. Especially when the material has high moisture content, the accumulated material will further block the airflow channel and aggravate the air velocity imbalance. At this time, the equipment needs to be stopped and disassembled for cleaning, which not only has high maintenance costs, but also causes a long production interruption time. Therefore, in order to solve the above problems, a feed pipe structure for a roller press V-type air classifier is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a feeding pipe structure for a roller press V-type classifier, so as to solve the problem that the feeding pipe structure of some existing roller press V-type classifiers cannot adjust the air guide plate, and that materials easily accumulate at the air inlet and the side wall near the air inlet.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A feed pipe structure for a roller press V-type classifier includes an outer shell assembly, an air guide assembly, and a cleaning assembly. The outer shell assembly includes an outer shell body. The air guide assembly is located inside the left half of the outer shell body. The air guide assembly includes multiple rotating shafts rotatably connected to the outer shell body. Air guide plates located inside the outer shell body are fixedly connected to the outer sides of each rotating shaft. A pointer dial is fixedly connected to the front end of each rotating shaft. Multiple locking sleeves rotatably connected to the rotating shafts are fixedly connected to the front side of the outer shell body. Each locking sleeve has a set of graduated grooves on its front side. The left side of each component is threaded with locking bolts that fit tightly against the rotating shaft at the tail end. A cleaning component is provided on the lower left side of the air guide assembly. The cleaning component includes a mounting bracket, on which multiple diversion pipes located diagonally below the air guide plate are mounted. Each diversion pipe is fixedly connected to a set of communicating jet nozzles near the mounting bracket. The front end of each diversion pipe is bolted to a communicating air supply pipe. Each air supply pipe has an electromagnetic pulse valve installed in the middle section. The front side of the outer casing is fixedly connected to a diversion shell that is fixedly connected to and communicating with multiple electromagnetic pulse valves.

[0006] Preferably, the upper surface of the left half of the outer shell is provided with a feed inlet, the left inclined surface of the outer shell is provided with an air inlet, the lower surface of the outer shell is provided with a discharge outlet, the upper surface of the right half of the outer shell is provided with an air outlet, and a baffle plate is fixedly connected inside the right half of the outer shell.

[0007] Preferably, both the front and rear ends of the air guide plate are in contact with the inner wall of the outer casing, the pointer dial points in the same direction as the air guide plate, and each set of scale grooves is evenly distributed at the edge of the locking sleeve.

[0008] Preferably, the mounting bracket consists of a rectangular frame fixedly connected to the left inclined surface of the outer casing and multiple pairs of detachable "U"-shaped frames, with the diversion pipes all located inside the "U"-shaped frames of the mounting bracket.

[0009] Preferably, each group of jet nozzles is evenly distributed horizontally, each group of jet nozzles passes through the rectangular frame gap of the mounting bracket, and each group of jet nozzles passes through the left inclined surface of the outer shell and is tightly fitted to the outer shell.

[0010] Compared with the prior art, the beneficial effects of this utility model are: In this invention, the device, through the inclusion of a pointer dial, locking sleeve, locking bolt, diverter pipe, jet nozzle, and electromagnetic pulse valve, allows for angle adjustment of the rotating shaft and guide plate via the lockable locking bolt and locking sleeve. The tilt angle of the guide plate is determined by the pointer dial and scale groove. Simultaneously, the on / off electromagnetic pulse valve periodically delivers high-pressure gas into the diverter pipe, which is then ejected through the jet nozzle to clean the inner side of the guide plate and the left side wall of the outer casing, preventing material accumulation. This device can adjust the guide plate according to material characteristics and airflow requirements, avoiding "air short circuits" and ensuring the sorting accuracy and efficiency of the V-type classifier. Furthermore, the device prevents material accumulation and avoids airflow imbalance. Therefore, this device does not require disassembly for cleaning and can be used continuously without shutdown, resulting in low maintenance costs. Attached Figure Description

A diversion shell 36 is fixedly connected to the front side of the outer shell 11 and is fixedly connected to and connected to multiple electromagnetic pulse valves 35.

[0017] A feed inlet 12 is provided on the upper surface of the left half of the outer casing 11, an air inlet 13 is provided on the inclined left side of the outer casing 11, a discharge outlet 14 is provided on the lower surface of the outer casing 11, and an air outlet 15 is provided on the upper surface of the right half of the outer casing 11. A baffle plate 16 is fixedly connected inside the right half of the outer casing 11. The inclined baffle plate 16 can block the wind, thereby reducing the wind speed and preventing the upward blowing of the outer casing 11 from carrying away the material. The front and rear ends of the air guide plate 22 are both in contact with the inner wall of the outer casing 11. The pointer dial 23 points in the same direction as the air guide plate 22. Each set of scale grooves 25 is evenly distributed on the edge of the locking sleeve 24. The pointer dial 23 and the scale grooves 25 can be used to accurately adjust the... The tilt angle of the guide vanes 22 is such that multiple guide vanes 22 have different tilt angles; the mounting frame 31 consists of a rectangular frame fixedly connected to the left inclined surface of the outer casing 11 and multiple pairs of detachable "U"-shaped frames. The diversion pipes 32 are all located inside the "U"-shaped frames of the mounting frame 31, and the diversion pipes 32 can be fixed by the mounting frame 31; each set of jet nozzles 33 is evenly distributed horizontally, each set of jet nozzles 33 passes through the gap of the rectangular frame of the mounting frame 31, and each set of jet nozzles 33 passes through the left inclined surface of the outer casing 11 and is tightly fitted to the outer casing 11. Compressed gas can be sprayed through the jet nozzles 33 to clean the inner side of the guide vanes 22 and the left side wall of the outer casing 11 to prevent material accumulation.

[0018] Workflow: Before use, install the outer casing 11 in a suitable position on the V-type air classifier and connect the power supply to the device. The feed inlet 12 of the device is welded to the discharge end of the roller press, and the discharge outlet 14 is connected to the feed end of the V-type air classifier via a flange. The air inlet 13 of the device is connected to the air outlet of the first air pump, and the diverter shell 36 is connected to the air outlet of the second air pump. The device is equipped with an external controller, which is electrically connected to multiple electromagnetic pulse valves 35. Manual operation of the external controller can adjust the operating status of multiple electromagnetic pulse valves 35. All of the above are existing technologies. Before using the device, the operator first loosens the locking bolts 26 on the locking sleeve 24 and rotates the pointer dial 23 to make the rotating shaft 21 and the air guide... The plate 22 rotates accordingly, and the tilt angle of the air guide plate 22 can be accurately adjusted through the pointer dial 23 and the scale groove 25, so that multiple air guide plates 22 have different tilt angles. Then, tighten the locking bolt 26 to lock the rotating shaft 21. From left to right, make the first group and the second group of air guide plates 22 vertically distributed and the bottom end of the air guide plate 22 in contact with the left inclined inner wall of the outer shell 11 (closing angle 90°, fully closed), make the wall of the third group of air guide plates 22 tilted at 75° (closed 2 / 3), and make the fourth group of air guide plates 22 tilted at 67°.With a 5° tilt angle (closed 1 / 2), the fifth group of air guide plates 22 is tilted at a 60° angle (closed 1 / 3), and the sixth and seventh groups of air guide plates 22 are fully extended (parallel to the airflow direction). When using this device, the operator first starts the roller press, the first air pump, and the V-selector. The material discharged from the roller press outlet enters the outer casing 11 through the feed inlet 12. As the material falls from the feed inlet 12, the first air pump delivers gas into the outer casing 11 through the air inlet 13. The blowing angle and air volume can be adjusted by the air guide plates 22 fixed by the rotating shaft 21, which can break up the cake material and make it fall from the discharge outlet 14 into the feed end of the V-selector. Excess gas can be discharged through the air outlet 15. The inclined baffle plate 16 can block the wind, thereby reducing the wind speed and preventing the wind blowing upward out of the outer casing 11 from carrying away the material. At the same time, the external controller can control the second air pump to start once at a specific time interval. When the dual air pump is turned on, compressed air is supplied to the air delivery pipe 34 through the distribution shell 36. The compressed air opens the solenoid pulse valve 35, and the compressed air is delivered through the air delivery pipe 34 and the solenoid pulse valve 35 to the distribution pipe 32 fixed by the mounting bracket 31. Then, it is ejected through the nozzle 33, which cleans the inner side of the air guide plate 22 and the left side wall of the outer casing 11 to prevent material accumulation. The device can adjust the angle of the rotating shaft 21 and the air guide plate 22 by using the lockable locking bolt 26 and the locking sleeve 24. The tilt angle of the air guide plate 22 is determined by the pointer dial 23 and the scale groove 25. At the same time, the switchable solenoid pulse valve 35 delivers high-pressure gas to the distribution pipe 32 periodically, and the high-pressure gas is ejected through the nozzle 33 to clean the inner side of the air guide plate 22 and the left side wall of the outer casing 11 to prevent material accumulation. The device can adjust the air guide plate 22 according to the material characteristics and air volume requirements to avoid "air short circuit". This phenomenon ensures the V-type air classifier's accuracy and efficiency in material sorting. Furthermore, the device prevents material accumulation and avoids airflow imbalance; therefore, it does not require disassembly for cleaning and can be used continuously without shutdown, resulting in low maintenance costs.
