Description

Technical Field

[0001] This utility model relates to the field of double-toothed roller crushing technology, specifically to a combing device for an anti-sticking double-toothed roller crusher. Background Technology

[0002] Laterite nickel ore is an important metallic mineral resource, attracting significant attention due to its abundant content of nickel, iron, cobalt, and other metallic elements. Globally, laterite nickel ore reserves are plentiful and widely distributed, and its relatively low extraction costs have made it a crucial component of the global nickel supply. However, with the continuous expansion of the laterite nickel ore market, its mining has encountered new challenges. As mining continues, the quality of nickel ore in the mining areas is showing a declining trend. During the mining process, the useful components in the ore gradually decrease, and the proportion of excessively large and numerous stones gradually increases, placing considerable pressure on the entire mining process.

[0003] Currently, commonly used crushing equipment includes cone crushers, jaw crushers, impact crushers, and roller crushers. Among them, roller crushers have advantages such as simple maintenance, low power consumption, high productivity, and small size. However, the toothed rollers of existing roller crushers are mostly integral structures. The high proportion of stones in the ore exacerbates the wear of the crushing equipment. After the tooth surface wears down, the entire machine needs to be disassembled and replaced for maintenance, resulting in high maintenance costs and long downtime. During the crushing process, sticky ores tend to adhere to the tooth surface, requiring the installation of comb plates. However, the traditional method of fixing comb plates has poor reliability. After long-term exposure to the impact of ores and equipment vibration, the comb plates are prone to loosening and falling off. Once the comb plates fall off, they will directly hit the conveyor belt below, causing serious damage such as tearing and scratching. This not only significantly increases the cost of belt replacement but also interrupts the production process due to downtime for maintenance, thus affecting the operating efficiency of the production line.

[0004] The purpose of this invention is to provide a non-sticking combing device for a double-toothed roller crusher to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A combing device for an anti-sticking double-toothed roller crusher includes:

[0007] The base has a crusher fixedly connected to its top via a main support for crushing materials. The top of the crusher has a feed inlet fixedly connected to it. A double-toothed roller crushing assembly is located below the feed inlet, and a discharge hopper is located below the double-toothed roller crushing assembly.

[0008] A conveyor belt is installed inside the base, and the outlet of the discharge hopper is aligned with the upper end face of the conveyor belt. The conveyor belt is inclined.

[0009] A fixed base plate is fixedly connected inside the base, and a rinsing component is provided on the upper surface of the fixed base plate for rinsing the conveyor belt.

[0010] The double-toothed roller crushing assembly includes a toothed roller, which is rotatably connected inside the crusher. The outer surface of the toothed roller is provided with a single tooth, which is inserted into the toothed roller through a bottom-fixed insert block.

[0011] Preferably, the rotating shaft of the toothed roller passes through the crusher and reaches the outside to connect with the driven wheel.

An insertion port is fixedly connected above the installation groove. The insertion block at the bottom of the single tooth is inserted into the installation groove and fixed by fixing bolts.

[0012] Preferably, the fixing bolt extends from one side of the socket, through the socket and the plug block, to the other side of the socket, and the fixing bolt is secured by a nut.

[0013] Preferably, the double-toothed roller crushing assembly further includes a comb plate, the front end of which is fixedly connected with comb teeth, the shape of which meshes with the single teeth on the toothed roller.

[0014] Preferably, the comb plate is installed on both sides inside the crusher by fixing clamps, and a suspension plate is fixedly connected to the upper end face of the fixing clamps, and the suspension plate is fixedly connected inside the crusher.

[0015] Preferably, both the fixing plate and the comb plate have through holes, and fixing pins are inserted into the through holes to fix the comb plate and the fixing plate.

[0016] Preferably, the rinsing assembly includes a water pump, which is fixedly connected to the upper end face of the fixed base plate. The upper end of the water pump is connected to a return pipe, and the lower end is connected to a water supply pipe.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This invention features a toothed roller with individually replaceable single teeth. The roller teeth are covered with wear-resistant material, allowing for easy disassembly, repair, or replacement when the weld overlay wears down, thus reducing maintenance workload.

[0021] In this invention, the comb tooth plate is installed inside the crusher via a fixing clamp and a suspension plate. During operation, it cleans the residue on the surface of the single tooth, improving crushing efficiency. Furthermore, it is connected by a fixing pin and a wing nut, allowing for disassembly by a single person. Simply open the crusher housing, unscrew the wing nut, and the fixing pin can be quickly pulled out, enabling the disassembly and replacement of the comb tooth plate.

[0022] In this invention, the comb plate is used in conjunction with a fixed clamping plate. Most of the surface of the comb plate is held by the fixed clamping plate, which avoids deformation or breakage of the comb plate caused by local stress concentration. During operation, the weight of the comb plate and the scraping resistance are evenly transmitted to the two side walls of the crusher through the fixed clamping plate and the suspension plate, which avoids overload of the single-sided suspension device due to the shift of the center of gravity and reduces the risk of loosening or breakage of the comb plate.

[0023] This invention features a flushing assembly that sprays high-pressure water to flush the conveyor belt. Wastewater and mineral materials enter a sedimentation tank through a recovery port, where they settle, the mineral materials are recovered, and the water is recycled. The water is then returned to the pump for further recycling via an external pump and a return pipe. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Example:

[0035] Please see Figures 1 to 8 This utility model provides a technical solution:

[0036] A combing device for an anti-sticking double-toothed roller crusher includes:

[0037] A base 1 is provided, and a crusher 3 is fixedly connected to the top of the base 1 via a main support 2 for crushing materials. A feed port 4 is fixedly connected to the top of the crusher 3. A double toothed roller 6 crushing assembly is provided below the feed port 4. A discharge hopper 5 is provided below the double toothed roller 6 crushing assembly.

[0038] The conveyor belt 7 is installed inside the base 1, and the outlet of the discharge hopper 5 is aligned with the upper surface of the conveyor belt 7. The conveyor belt 7 is installed at an angle.

[0039] A fixed base plate 102 is fixedly connected inside the base 1. A rinsing assembly is provided on the upper surface of the fixed base plate 102 for rinsing the conveyor belt 7.

[0040] The double toothed roller 6 crushing assembly includes a toothed roller 6, which is rotatably connected inside the crusher 3. The outer surface of the toothed roller 6 is provided with a single tooth 604, which is inserted into the toothed roller 6 through a bottom fixedly connected insert block 606.

[0041] Specifically, the rotating shaft of the toothed roller 6 passes through the crusher 3 and reaches the outside to connect with the driven wheel 601. The driven wheel 601 is rotatably connected to the output end of the reduction motor 602 through the transmission belt 603. The surface of the toothed roller 6 is provided with an installation groove 605. An insertion port 607 is fixedly connected above the installation groove 605. The insertion block 606 at the bottom of the single tooth 604 is inserted into the installation groove 605 and fixed by the fixing bolt 608.

[0042] Specifically, the toothed roller 6 adopts the overlay roller tooth technology, which overlays a layer of wear-resistant alloy material (such as high-chromium cast iron or tungsten carbide alloy) with a thickness of 3 to 5 mm on the surface of a single tooth 604, extending the service life of the equipment. The single tooth 604 adopts an independent detachable design. When the overlay layer is worn to a thickness of less than 1 mm, the single tooth 604 can be disassembled separately for secondary overlay repair, which is low cost.

[0043] In this embodiment, the geared motor 602 is fixedly connected to the main support 2. The double toothed roller 6 crushing assembly includes two toothed rollers 6. The two toothed rollers 6 are controlled by two geared motors 602 respectively. The geared motors 602 are electrically connected to an external controller. The external controller controls the speed of the geared motors 602 to keep the two toothed rollers 6 at the same speed. The material falls from the feed port 4 and is crushed between the double toothed rollers 6.

[0044] In this embodiment, the toothed roller 6 has multiple mounting grooves 605, and the top of the mounting groove 605 is fixedly connected to an insertion port 607 (e.g., Figure 8 The toothed roller 6 has multiple single teeth 604, each of which is an independent structure and integrally formed. A plug 606 is fixedly connected to the bottom of the single tooth 604. The plug 606 matches the shape of the mounting groove 605. During installation, the bottom of the plug 606 is aligned with the top of the insertion port 607 and inserted into the mounting groove 605. When the plug 606 is inserted to the bottom, the through hole on the plug 606 is aligned with the threaded opening on the side of the insertion port 607. The single tooth 604 is fixed to the toothed roller 6 by using the threaded engagement of the fixing bolt 608 and the nut.

[0045] Specifically, the fixing bolt 608 extends from one side of the socket 607, through the socket 607 and the plug block 606, to the other side of the socket 607, and the fixing bolt 608 is fixed by a nut.

[0046] Specifically, the double-toothed roller 6 crushing assembly also includes a comb plate 10, with comb teeth fixedly connected to the front end of the comb plate 10. The shape of the comb teeth meshes with the single teeth 604 on the toothed roller 6, and the comb teeth avoid the insertion port 607 and the fixing bolt 608.

[0047] Specifically, the comb plate 10 is installed on both sides inside the crusher 3 by a fixing clamp 9, and a suspension plate 901 is fixedly connected to the upper end face of the fixing clamp 9, and the suspension plate 901 is fixedly connected inside the crusher 3.

[0048] Specifically, both the fixing plate 9 and the comb plate 10 are provided with through holes, and fixing pins 11 are inserted into the through holes to fix the comb plate 10 and the fixing plate 9.

[0049] In this embodiment, each toothed roller 6 is provided with a comb plate 10 at its rear end. The rotation of the toothed roller 6 itself scrapes the mineral material adhering to the single tooth 604 of the toothed roller 6 clean. The comb plate 10 has a certain thickness, which ensures the strength of the comb plate 10 and reduces the risk of sudden breakage of the comb plate 10 under long-term use.

[0050] Because the comb plate 10 is relatively thick, it is connected to the fixed clamping plate 9 to support its weight. The fixed clamping plate 9 is suspended on both sides of the inside of the crusher 3 by the suspension plate 901. While ensuring sufficient connection strength, the height of the comb plate 10 is reduced, so that the center of the comb plate 10 and the toothed roller 6 are on the same horizontal plane. The weight of the comb plate 10 and the scraping resistance are evenly transmitted to both sides of the crusher 3 through the fixed clamping plate 9 and the suspension plate 901, avoiding overload of the single-sided suspension device due to the shift of the center of gravity and reducing the risk of the comb plate 10 loosening or breaking.

[0051] Specifically, most of the surface of the comb plate 10 is clamped by the fixing plate 9 to avoid deformation or breakage of the comb plate 10 caused by local stress concentration.

[0052] In this embodiment, a fixing pin 11 is inserted into the through hole of the fixing clamp 9 and the comb plate 10. After being inserted into the through hole, a wing nut is screwed in. The tightening force of the nut makes the fixing clamp 9 and the comb plate 10 fit tightly together, maintaining stability during operation. When disassembling, simply open the outer shell of the crusher 3, unscrew the wing nut, and the fixing pin 11 can be quickly pulled out to disassemble and replace the comb plate 10. This can be operated by a single person and is convenient to use.

[0053] Specifically, the rinsing assembly includes a water pump 8, which is fixedly connected to the upper surface of the fixed base plate 102. The upper end of the water pump 8 is connected to a return pipe 801, and the lower end is connected to a water supply pipe 802. The water supply pipe 802 is connected to a rinsing tank 803, which is fixedly connected to the upper surface of the fixed base plate 102. A rinsing head 804 is provided at the front end of the rinsing tank 803.

[0054] Specifically, the water pump 8 is electrically connected to an external controller, which can be set to start flushing at a timed interval or manually.

[0055] In this embodiment, the flushing assembly's flushing box 803, together with the flushing head 804 and the water pump 8, sprays high-pressure water to flush the surface of the conveyor belt 7, removing the ore material adhering to the working surface of the belt. After flushing, the wastewater and powdery soil ore enter the sedimentation tank through the recovery port under the base 1 for sedimentation, ore recovery, and water recycling. The water is then returned to the water pump 8 for recycling through an external pump and return pipe 801.

[0056] Specifically, the left and right ends of the fixed base plate 102 are fixedly connected to the inner wall of the base 1, and the base plate bracket 201 is fixedly connected below the main bracket 2. The base plate bracket 201 is connected to the upper surface of the fixed base plate 102.

[0057] Specifically, the front end of the base 1 is provided with a discharge port 101 for discharging material from the conveyor belt 7. The conveyor belt 7 has a drive shaft 701, which is driven by a motor (not shown in the figure) inside the base 1.

[0058] In use, material enters through the top feed port 4 of the crusher 3. Two reduction motors 602 are synchronously controlled to drive the double toothed rollers 6 to rotate in opposite directions at the same speed. The toothed rollers 6 shear the material with their single teeth 604 to achieve crushing. The crushed material falls into the discharge hopper 5 and is conveyed to the front discharge port 101 of the base 1 via the inclined conveyor belt 7. During the process, the water pump 8 of the rinsing component pressurizes water into the rinsing tank 803 through the water pipe 802, and high-pressure water is sprayed through the rinsing head 804 to clean the surface of the belt. The attached mineral materials, sewage and soil enter the sedimentation tank through the recycling port. The mineral materials are recycled and reused. The water resources are circulated to the water pump 8 through the return pipe 801. The comb plate 10 is stably installed in the crusher 3 through the fixing clamp 9 and the suspension plate 901. Its comb teeth mesh with the single teeth 604 of the tooth roller 6. As the tooth roller 6 rotates, it scrapes off the sticky material. The fixing pin 11 and the butterfly nut enable the quick disassembly and assembly of the comb plate 10. When the weld overlay layer of the single tooth 604 is worn, the single tooth 604 fixed by the insert block 606 can be removed separately for repair.

[0059] All other parts of this utility model not described herein are the same as existing technologies, or are known technologies, or can be implemented using existing technologies, and will not be described in detail here.

[0060] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
