Description

Technical Field

[0001] The utility model relates to waste oil barrel processing equipment, in particular to an anti-blocking waste oil barrel crusher. Background Art

[0002] Waste oil drums are iron packaging barrels that are discarded after the oil in them is used up in industry or life. Common oils include paint and ink. In order to facilitate the recycling and remelting of waste oil drums, the waste oil drums need to be shredded.

[0003] In practice, it is found that when a small number of waste oil barrels, such as one or two, are pushed into the shredder, a single layer of waste oil barrels is laid on the shredder's rollers, and the waste oil barrels roll for a certain period of time before being scraped and bitten by the rollers, resulting in low efficiency in crushing the waste oil barrels. Therefore, more waste oil barrels are generally pushed into the shredder; in the shredder, the top waste oil barrel pushes the bottom waste oil barrel toward the rollers, so that the waste oil barrels can be scraped and shredded effectively and quickly.

[0004] However, blindly caching a large number of waste oil barrels in the shredder can easily cause the shredder to get stuck. Therefore, it is necessary to solve the problem of blindly caching waste oil barrels in the shredder. Utility Model Content

[0005] The utility model aims to solve at least one of the above-mentioned technical problems and provides an anti-blocking waste oil barrel crusher. When the accumulated waste oil barrels in the shredder reach a high level, sound and light warnings are given to avoid blindly pushing the waste oil barrels into the shredder.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0009] As an improvement of the above technical solution, the cache column is also provided with a low-level detection sensor lower than the high-level detection sensor. The low-level detection sensor is electrically connected to a second alarm through a central controller or a power-off delay relay. When the pile height of the waste oil barrels in the cache column is lower than the low-level detection sensor, the central controller or the power-off delay relay starts timing. The second alarm includes a warning light. The second alarm is suitable for starting after the low-level detection sensor is continuously powered off for T time.

[0014] As an improvement of the above technical solution, the high-position detection sensor and the low-position detection sensor are both connected to two locking nuts to be clamped on the peripheral wall of the cache cylinder, and the through hole of the protective ring is suitable for accommodating the corresponding locking nuts and limiting the rotation of the locking nuts.

[0015] As an improvement of the above technical solution, a first buffer structure and a second buffer structure are alternately distributed in the up and down directions in the cache vertical cylinder, the height difference between the first buffer structure and the second buffer structure allows the waste oil barrel to pass through, the first buffer structure is two first buffer inclined plates distributed in an inverted eight shape, and a first blanking gap is formed between the two first buffer inclined plates, and the second buffer structure is an arched arc plate, and the side end of the arched arc plate forms a second blanking gap with the inner wall of the cache vertical cylinder, and the first blanking gap and the second blanking gap are staggered.

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figures 1 to 5 The utility model provides an anti-blocking waste oil barrel crusher, including a chassis 100, a high-position detection sensor SQ1 and a first alarm HL1. The chassis 100 includes a seat box 110 and a cache vertical cylinder 120 connected to the upper port of the seat box 110. The seat box 110 is suitable for installing two horizontally arranged twisting rollers 200, and the two twisting rollers 200 are suitable for tearing the waste oil barrel together. The high-position detection sensor SQ1 is installed on the cache vertical cylinder 120. A certain amount of waste oil barrels stacked in the cache vertical cylinder 120 can trigger the high-position detection sensor SQ1 to turn on. The first alarm HL1 is electrically connected to the high-position detection sensor SQ1 through a central controller or a power-on delay relay KT1. The first alarm HL1 includes a buzzer and / or a warning light. The first alarm HL1 is suitable for starting after the high-position detection sensor SQ1 is continuously powered on for T time, warning the shredder to suspend feeding.

[0033] It is understood that the twisting roller 200 is connected to a corresponding motor, such as a hydraulic motor or an electric motor. The two twisting rollers 200 generally rotate in opposite directions, and when the twisting roller 200 rotates, the tangential direction of its upper edge is from itself to the other twisting roller 200.

[0034] The seat box 110 and the cache stand 120 are integrally formed or detachably connected.

[0035] Specifically, the operation process of the utility model is as follows, referring to Figure 5, the high-level detection sensor SQ1 is electrically connected to the coil of the power-on delay relay KT1, and the normally open contact of the power-on delay relay KT1 is electrically connected to the first alarm HL1; according to the general knowledge of the power-on delay time relay, the power-on delay reaction time T of the power-on delay relay KT1 is adjusted, T≥3 seconds, after the high-level detection sensor SQ1 is turned on, the coil of the power-on delay relay KT1 starts to be energized, and the timing starts (power-on delayed reaction, power-off immediate reaction), when the high-level detection sensor SQ1 is continuously turned on for T, that is, when the continuous energization time of the coil of the power-on delay relay KT1 meets the set time T, the normally open contact of the power-on delay relay KT1 is turned on (that is, the power-on delay relay KT1 delays the reaction after power-on, and its output circuit undergoes a jump change after being powered on for T time). Correspondingly, when the pile height of the waste oil barrels in the cache column 120 reaches the trigger height of the high-level detection sensor SQ1, the high-level detection sensor SQ1 is turned on; when the pile height of the waste oil barrels in the cache column 120 is continuously greater than the high-level line, and the duration of this continuous characteristic reaches T, the power-on delay relay KT1 delays for a sufficient period of T, and its normally open contacts close, causing the first alarm HL1 to conduct and emit an audible and visual alarm, so that the on-site workers know that there are too many waste oil barrels cached in the shredder, and then suspend the feeding of the shredder.

[0036] During the pause of feeding, the shredder continues to digest the waste oil barrels cached in it; Figure 5 As for the working principle of the time relay (delayed reaction when power is on, immediate reaction when power is off), when the pile height of the waste oil barrels in the shredder is lower than the high level line, the high level detection sensor SQ1 is powered off, the coil of the power-on delay relay KT1 is powered off, and the normally open contacts of the power-on delay relay KT1 immediately return to normal.

[0037] In some settings, intelligent chips such as central controllers are used, which integrate timers, counters, A / D converters, input and output interfaces, such as MCU, computers, PLC controllers, etc.; the high-level detection sensor SQ1 and the first alarm HL1 are respectively connected to the corresponding contacts of the input and output interfaces of the central controller. The central controller timer has the same delay principle as the time relay, and the high-level trigger duration T is set in the central controller; after the high-level detection sensor SQ1 is turned on, the central controller starts timing, and the waste oil barrels in the cache cylinder 120 are continuously greater than the high-level line, and the duration reaches T, that is, when the central controller continues to time T, the central controller starts the first alarm HL1, and an audible and visual alarm is issued on site.

[0038] In addition, the high-position detection sensor SQ1 can be a proximity sensor / proximity switch (non-contact detection sensor), etc., such as capacitive, inductive, and photoelectric proximity sensors, which are common knowledge. Because the waste oil barrel is a cylinder with a relatively large diameter, the waste oil barrel is in a side-lying / falling-down state after being placed in the shredder. The high-position detection sensor SQ1 is generally set on the peripheral wall of the buffer cylinder 120. When the waste oil barrel is lying on its side, the highest point is at a certain distance from the inner wall of the buffer cylinder 120. Preferably, the high-position detection sensor SQ1 is set horizontally. This type of proximity sensor uses a high-precision long-distance type. For example, if the diameter of the waste oil barrel is 750mm, the sensitivity of the proximity sensor is ≥750 / 2mm; preferably, a photoelectric proximity sensor with a longer distance measurement is used.

[0039] Compared with the prior art, the beneficial effects of the present application include: when a large number of waste oil barrels are cached in the chassis 100, the high-level detection sensor SQ1 will detect it and drive the first warning device HL1 to sound and light alarm, so that the chassis 100 can stop feeding, avoid load blockage of the shredder, and ensure that the shredding of the waste oil barrels can be sustainable.

[0040] When most of the waste oil barrels are consumed in the shredder, a small amount of waste oil barrels tend to slip and roll. Figures 1 to 5 Preferably, the cache column 120 is also provided with a low-level detection sensor SQ2 which is lower than the high-level detection sensor SQ1. The low-level detection sensor SQ2 is electrically connected to the second alarm HL2 through the central controller or the power-off delay relay KT2. The power-off delay relay KT2 is the abbreviation of the power-off delay time relay. When the pile height of the waste oil barrels in the cache column 120 is lower than the low-level detection sensor SQ2, the central controller or the power-off delay relay KT2 starts timing. The second alarm HL2 includes a warning light. The second alarm HL2 is suitable for starting after the low-level detection sensor SQ2 is continuously powered off for T time period.

[0041] According to the working principle of the time relay, refer to Figure 5 The power-on delay relay KT1 / counter corresponding to the high-level detection sensor SQ1 is a power-on delay reaction, and the power-off delay relay KT2 / counter corresponding to the low-level detection sensor SQ2 is a power-off delay reaction.

[0042] Specifically, the operation of stacking waste oil barrels is as follows: Figure 5, the low-level detection sensor SQ2 is electrically connected to the coil of the power-off delay relay KT2, and the normally closed contact of the power-off delay relay KT2 is electrically connected to the second alarm HL2; according to the general knowledge of time relays, the delayed reaction time T of the power-off delay relay KT2 is adjusted, T≥3 seconds; according to the working principle of the power-off delay time relay (immediate reaction when power is on, delayed reaction when power is off), when the waste oil barrel in the cache column 120 continues to be at a high level, the low-level detection sensor SQ2 is continuously turned on, the coil of the power-off delay relay KT2 is continuously energized, the normally closed contact of the power-off delay relay KT2 is continuously disconnected, and the second alarm HL2 does not work; the amount of waste oil barrels in the cache column 120 begins to be lower than the low-level detection sensor SQ2, the low-level detection sensor SQ2 begins to disconnect, the power-off delay relay KT2 coil is de-energized, and the power-off delay relay KT2 begins to calculate the power-off duration. When the low-level detection sensor SQ2 is continuously disconnected for T, that is, when the power-off duration of the power-off delay relay KT2 coil meets the set duration T, the power-off delay relay KT2 reacts, and the normally closed contacts of the power-off delay relay KT2 resume closing (that is, the power-off delay relay KT2 reacts to the power-off delay, and its output circuit undergoes a jump-like change after the power-off continues for T duration). The second alarm HL2 conducts and sends out an audible / visual alarm. The on-site workers know that there are too few waste oil barrels cached in the shredder, or even no waste oil barrels, and the shredder needs to be fed.

[0043] Reference Figure 4 In some embodiments of the present invention, a feed conveyor belt 300 is also included. The feed conveyor belt 300 is suitable for feeding waste oil barrels into the buffer cylinder 120. The high-level detection sensor SQ1, the low-level detection sensor SQ2 and the feed conveyor belt 300 are electrically connected to the central controller. The feed conveyor belt 300 is suitable for starting after the low-level detection sensor SQ2 is continuously powered off for a period of T, and the feed conveyor belt 300 is suitable for stopping after the high-level detection sensor SQ1 is continuously powered on for a period of T. In the present invention, the central controller centrally controls the high-level detection sensor SQ1, the low-level detection sensor SQ2 and the feed conveyor belt 300, and the shredder feeds intelligently; that is, the shredder refills when the level is low, and stops refilling when the level is high.

[0044] As is known in the art, the feed conveyor belt 300 comprises a belt, a plurality of pulleys, and a motor for driving and connecting the pulleys. In the present invention, fences are arranged on both sides of the feed conveyor belt 300 to prevent the waste oil barrel from deviating from the feed conveyor belt 300.

[0045] Reference Figures 1 to 4 In some embodiments of the present invention, a feed hopper 130 is supported at the upper end of the buffer column 120 , and a feed conveyor belt 300 feeds waste oil barrels into the buffer column 120 through the feed hopper 130 .

[0046] Reference Figures 2 to 4In some embodiments of the present invention, a protective ring 121 is provided on the inner wall of the cache column 120 , and the high-position detection sensor SQ1 and the low-position detection sensor SQ2 are both inserted into the inner bore of the cache column 120 and surrounded by the corresponding protective ring 121 .

[0047] Reference Figures 1 to 3 In some embodiments of the present invention, the outer wall of the cache vertical tube 120 is provided with multiple reinforcing ribs at intervals along the circumferential direction, and the exposed parts of the high-position detection sensor SQ1 and the low-position detection sensor SQ2 are hidden in the gap between the corresponding two reinforcing ribs. The reinforcing ribs not only solve the strength problem of the chassis 100, but also solve the safety of the high-position detection sensor SQ1 and the low-position detection sensor SQ2 to a certain extent, and the equipment and personnel outside the chassis 100 are not easy to bump into the high-position detection sensor SQ1 and the low-position detection sensor SQ2.

[0048] Reference Figures 2 to 4 In some embodiments of the present invention, the high-position detection sensor SQ1 and the low-position detection sensor SQ2 are connected to two locking nuts to be clamped on the peripheral wall of the cache column 120. The through hole of the protective ring 121 is suitable for accommodating the corresponding locking nuts and limiting the rotation of the locking nuts. When the high-position detection sensor SQ1 and the low-position detection sensor SQ2 are disassembled, the locking nuts on the inner side of the cache column 120 do not need to be supported or disassembled.

[0049] Reference Figures 2 to 4 In some embodiments of the present invention, a first buffer structure and a second buffer structure are staggeredly distributed in the vertical direction of the cache cylinder 120. The height difference between the first buffer structure and the second buffer structure allows the waste oil barrel to pass through. The first buffer structure is two first buffer inclined plates 140 distributed in an inverted eight shape. The first blanking gap is between the two first buffer inclined plates 140. The second buffer structure is an arched arc plate 150. The side end of the arched arc plate 150 forms a second blanking gap with the inner wall of the cache cylinder 120. The first blanking gap and the second blanking gap are staggered. In the present invention, the process of the waste oil barrel falling from the upper port of the cache cylinder 120 to the twisting roller 200 is stopped multiple times to slow down the speed of the waste oil barrel when it lands. The second buffer structure is an arched arc plate 150, which not only solves the diversion problem, but also has a high bending strength.

[0050] Reference Figure 2 , Figure 3 In some embodiments of the present invention, a support platform 122 is provided on the inner wall of the buffer column 120, and the first buffer structure and the second buffer structure are detachably supported on the support platform 122. A gantry crane 410 is provided above the buffer column 120, and an electromagnet 420 is provided on the lifting ring of the gantry crane 410. The electromagnet 420 and the gantry crane 410 are suitable for jointly sucking away the waste oil barrel and / or iron material in the chassis 100. The iron material is obtained by crushing the waste oil barrel.

[0051] The lower end of the supporting platform 122 is a guide slope, which is suitable for the waste oil barrel and iron materials to be removed upward to prevent the waste oil barrel and iron materials from being firmly placed on the supporting platform 122.

[0052] Reference Figure 4 In some embodiments of the utility model, a gantry crane 410 is arranged above the cache cylinder 120, and an electromagnet 420 is arranged on the lifting ring of the gantry crane 410. The electromagnet 420 and the gantry crane 410 are suitable for jointly sucking away the waste oil barrel and / or iron material in the chassis 100. When the chassis 100 is blocked by material, the shredder is cleaned and maintained by the gantry crane 410.

[0053] Preferably, the electromagnet 420 descends to approach the waste oil barrel and iron material. When there is a certain gap between the electromagnet 420 and the waste oil barrel / iron material and the magnetic attraction can be exerted, the electromagnet 420 stops descending and drives the removable waste oil barrel / iron material upward by the magnetic attraction, that is, the electromagnet 420 absorbs the material through the air.

[0054] The electromagnet 420 preferably absorbs the material in the air, and part of the iron material is more firmly stuck in the seat box 110; better, refer to Figures 1 to 4 The side wall of the seat box 110 or the cache vertical cylinder 120 is provided with a discharge port 111, which is suitable for removing the iron material stuck in the seat box 110, and the discharge port 111 is detachably packaged with an end cover 160.

[0055] The above embodiments are only used to illustrate the technical solution of the utility model but not to limit it. Any modification or equivalent substitution that does not deviate from the spirit and scope of the utility model shall be included in the scope of the technical solution of the utility model.
