Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of cutting production devices, in particular to a basalt fiber production device and a production process. BACKGROUND

[0002] Basalt fibers are often used in the production process of concrete reinforcement. Before use, continuous basalt fibers need to be cut into short fibers, and then mixed with cement, sand and other matrix materials to form a concrete reinforcement mixture.

[0003] The cut basalt fibers are prone to mutual adhesion to form fiber clumps due to their own surface tension, static electricity or humidity, and are difficult to disperse naturally. The adhered fiber clumps are difficult to fully contact with the matrix material during subsequent stirring, resulting in uneven mixing, which directly affects the mechanical properties of the concrete and has certain disadvantages.

[0004] Therefore, a device is needed that can disperse basalt fibers during cutting production, facilitating subsequent stirring and mixing with other materials. SUMMARY

[0005] The technical problem to be solved by the present application is to overcome the shortcomings of the prior art and provide a cutting production device that can overcome the above problems or at least partially solve the above problems.

[0006] To solve the above technical problems, the basic idea of the technical solution adopted by the present application is as follows: a basalt fiber production device, comprising a support, a stirring assembly and a gas pump mounted on the support, further comprising: a pretreatment tank rotatably connected in the support, a blade in a spiral shape fixedly connected in the pretreatment tank, the pretreatment tank located above the stirring assembly, and the discharge end of the pretreatment tank facing the stirring assembly, and the pretreatment tank being arranged in a large size at the top and a small size at the bottom; a tank cover rotatably connected to the pretreatment tank, the tank cover being provided with an air inlet and a feed inlet; The air inlet is in communication with the gas outlet of the gas pump for injecting gas into the pretreatment tank. At the same time, the entering gas will form a spiral gas flow under the guidance of the blade, and then the cut fibers will be discharged through the discharge port at the bottom of the pretreatment tank along with the gas flow, and finally enter the stirring assembly; The feed inlet is used to put basalt fibers into the pretreatment tank; a cutting assembly installed in the pretreatment tank, the cutting assembly being used to cut the basalt fibers discharged from the feed inlet; The basalt fibers discharged from the feed inlet are cut by the cutting assembly, and the cut basalt fibers are blown apart along the spiral gas flow and finally enter the stirring assembly.

[0007] Further, the cutting assembly comprises a wave ring, a sliding rod, and a cutter. The wave ring is fixedly connected in the pretreatment tank. Two groups of sliding rods are slidingly connected in the pretreatment tank, and one end of each sliding rod abuts against a wave protrusion of the wave ring. The cutter is fixedly connected to the other end of each sliding rod. Two groups of cutters are oppositely arranged and located below the discharge end of the feed inlet. The cutter is used to cut the basalt fiber discharged below the feed inlet into strips.

[0008] Further, a plurality of piston cylinders are fixedly connected in the pretreatment tank. The extension end of each piston cylinder abuts against the wave protrusion of the wave ring. An air inlet pipe is connected to the air inlet end of each piston cylinder. The air outlet end of each piston cylinder faces the cutter. The rotation of the wave ring is driven by the pretreatment tank, and the extension end of the piston cylinder is continuously reciprocated with the sliding rod through the wave protrusion. The cutter continuously cuts the basalt fiber, and the air outlet end of the piston cylinder continuously discharges gas to prevent the basalt fiber from adhering to the cutter, so that the basalt fiber can be discharged along the spiral airflow.

[0009] Further, the bottom of the tank cover is fixedly connected with a mounting rod one and a mounting rod two. The mounting rod one is fixedly connected with the piston cylinder. The mounting rod two is connected with the sliding rod.

[0010] Further, a fixed block is slidingly connected to the sliding rod. A spring member is sleeved to the fixed block. The other end of the spring member abuts against the cutter. The mounting rod two is fixedly connected with the fixed block.

[0011] Further, a mounting plate is fixedly connected to the sliding rod. The cutter is fixedly connected to the mounting plate. The spring member abuts against the mounting plate.

[0012] Further, a nozzle is mounted to the air outlet end of the piston cylinder.

[0013] Further, a plurality of feeding rollers are symmetrically and rotatably connected in the feed inlet. The symmetrically installed feeding rollers are used to clamp the basalt fiber to slowly move downward, facilitating the cutting of the cutter. One end of each feeding roller is fixedly connected with a motor. The motor is used to drive the feeding roller to rotate.

[0014] Further, a servo motor is fixedly connected to the bracket. The output end of the servo motor is fixedly connected with a gear member. A gear ring is fixedly connected to the pretreatment tank. The gear ring is meshingly connected with the gear member.

[0015] The basalt fiber production process is used for a basalt fiber production device and mainly comprises the following operation steps. Step one: continuously input the basalt fiber into the pretreatment tank through the feeding roller in the feed inlet, and input the remaining mixed materials into the stirring assembly. Step two, start the air pump and servo motor, and then make the pretreatment tank rotate, so that the spiral airflow appears in the pretreatment tank; Step three, through the rotation of the wave ring, the cutting knife continuously cuts the basalt fibers discharged from the feeding port; Step four, the segmented basalt fibers after cutting are blown away by the spiral airflow, and then discharged through the discharge end of the pretreatment tank, so as to enter the stirring assembly; Step five, through the stirring assembly, the raw materials and basalt fibers are mixed together to obtain a concrete reinforcing mixed material.

[0016] After the above technical scheme is adopted, compared with the prior art, the present application has the following beneficial effects: through the cooperation of the cutting assembly and the piston cylinder, the cutting knife is sprayed with airflow through the nozzle after cutting, so that the fiber debris on the cutting edge is removed in real time, and the fiber adhesion during cutting is avoided; at the same time, the spiral airflow continuously stretches and blows away the short fibers after cutting, so that the fiber group is completely broken, and the subsequent stirring and mixing are facilitated.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments will be described clearly and completely below with reference to the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application but not to limit the scope of the present application.

[0020] Embodiment: Refer to Figures 1-8 , basalt fiber production device, including support 1, support 1 is installed with stirring assembly 101 and air pump, it also includes: pretreatment tank 2, rotationally connected in support 1, the blade 201 in pretreatment tank 2 is fixedly connected with spiral arrangement, pretreatment tank 2 is located above stirring assembly 101, and the discharge end is towards stirring assembly 101, and pretreatment tank 2 is arranged in big down small; tank cover 3, rotationally connected on pretreatment tank 2, tank cover 3 is provided with air inlet 301 and feed inlet 302; air inlet 301 is communicated with the air outlet end of air pump, for injecting gas into pretreatment tank 2, at the same time, the entering gas will form spiral airflow under the guidance of blade 201, in turn, the chopped fiber is discharged through the discharge port at the bottom of pretreatment tank 2, and finally enters stirring assembly 101; feed inlet 302 is used for feeding basalt fiber into pretreatment tank 2; cutting assembly, installed in pretreatment tank 2, cutting assembly is used for cutting basalt fiber discharged from feed inlet 302; basalt fiber discharged from feed inlet 302 is cut through cutting assembly, and the cut basalt fiber is finally blown into stirring assembly 101.

[0021] After the air pump is started, high-pressure gas enters pretreatment tank 2 through air inlet 301, at the same time, pretreatment tank 2 rotates around its own axis, and spiral blade 201 drives the gas to form spiral airflow, after the basalt fiber is fed from feed inlet 302, it is cut into short sections by cutting assembly, the short fibers are blown and slide down along the tank wall under the driving of spiral airflow, and finally enter stirring assembly 101 from the bottom discharge end, and are mixed with other materials.

[0022] The cutting assembly comprises a wave ring 5, sliding rods 701 and cutting knives 705. The wave ring 5 is fixedly connected in the pretreatment tank 2. Two groups of sliding rods 701 are slidingly connected in the pretreatment tank 2, and one end of each sliding rod 701 abuts against the wave protrusion of the wave ring 5. The cutting knives 705 are fixedly connected to the other end of the sliding rods 701. Two groups of cutting knives 705 are oppositely arranged and are both located below the discharge end of the feed inlet 302. The cutting knives 705 are used to cut the basalt fibers discharged below the feed inlet 302 into strips.

[0023] When the pretreatment tank 2 rotates, the wave ring 5 rotates synchronously. The wave-shaped outer surface of the wave ring 5 pushes the sliding rods 701 to reciprocate along the axial direction, and drives the two groups of cutting knives 705 to alternately open and close, thereby cutting the continuous fibers falling from the feed inlet 302 into segments.

[0024] A plurality of piston cylinders 601 are fixedly connected in the pretreatment tank 2. The extension end of each piston cylinder 601 abuts against the wave protrusion of the wave ring 5. The air inlet end of each piston cylinder 601 is connected with an air inlet pipe 602. The air outlet end of each piston cylinder 601 faces the cutting knife 705. The rotation of the wave ring 5 is driven by the pretreatment tank 2, and the extension end of the piston cylinder 601 is driven by the wave protrusion to continuously reciprocate with the sliding rod 701, thereby continuously cutting the basalt fibers by the cutting knife 705. At the same time, the air outlet end of the piston cylinder 601 continuously discharges gas, so as to avoid the basalt fibers adhering to the cutting knife 705 and enabling the basalt fibers to be discharged along with the spiral airflow.

[0025] When the wave ring 5 rotates, the wave surface pushes the piston rod of the piston cylinder 601 to reciprocate: when the piston rod is retracted, the gas enters the piston cylinder 601 through the air inlet pipe 602; when the piston rod is extended, the gas is sprayed at high speed through the nozzle 603, thereby blowing away the fiber debris adhering to the cutting knife 705 and assisting the fibers to move to the bottom of the tank.

[0026] The bottom of the tank cover 3 is fixedly connected with a mounting rod one 801 and a mounting rod two 802. The mounting rod one 801 is fixedly connected with the piston cylinder 601, and the mounting rod two 802 is connected with the sliding rod 701.

[0027] When the pretreatment tank 2 rotates, the mounting rod one 801 and the mounting rod two 802 remain stationary with the tank cover 3. The piston cylinder 601 and the sliding rod 701 only reciprocate along the axial direction, thereby avoiding the decrease in cutting accuracy caused by the radial shaking.

[0028] The sliding rod 701 is slidingly connected with a fixed block 702. The fixed block 702 is sleeved with a spring member 703. The other end of the spring member 703 abuts against the cutting knife 705. The mounting rod two 802 is fixedly connected with the fixed block 702.

[0029] When the wave ring 5 pushes the sliding rod 701 to move, the spring member 703 absorbs the impact force by elastic deformation, so that the opening and closing action of the cutter 705 is more stable, and the upper end of the sliding rod 701 is always in close contact with the wave ring 5.

[0030] The sliding rod 701 is fixedly connected with a mounting plate 704, and the cutter 705 is fixedly connected to the mounting plate 704. The spring member 703 abuts against the mounting plate 704.

[0031] The nozzle 603 is installed on the gas outlet end of the piston cylinder 601.

[0032] The gas discharged from the piston cylinder 601 forms a high-speed fan-shaped gas flow through the nozzle 603, which accurately blows to the cutting area of the cutter 705, preventing fiber adhesion and guiding the cut short fibers to the bottom of the tank.

[0033] A plurality of groups of feeding rollers 303 are symmetrically and rotatably connected in the feeding port 302. The symmetrically installed feeding rollers 303 are used to clamp the basalt fibers and make them slowly fall, facilitating the cutting of the cutter 705. A motor is fixedly connected to one end of the feeding roller 303, and the motor is not shown in the figure. If necessary, some gas can also be input into the feeding port 302 to prevent some fibers from entering the feeding port 302. The motor is used to drive the feeding roller 303 to rotate.

[0034] After the basalt fibers are put into the feeding port 302, they are clamped by the two groups of feeding rollers 303. The motor drives the feeding rollers 303 to rotate in the opposite direction, so that the fibers are transported downward at a constant speed to the cutter 705, ensuring uniform cutting length.

[0035] The bracket 1 is fixedly connected with a servo motor 401, the output end of the servo motor 401 is fixedly connected with a gear member 402, and the pretreatment tank 2 is fixedly connected with a tooth ring 403. The tooth ring 403 is in meshing connection with the gear member 402.

[0036] The basalt fiber production process mainly includes the following operation steps: Step one, continuously put basalt fibers into the pretreatment tank 2 through the feeding rollers 303 in the feeding port 302, and put the remaining mixed materials into the stirring assembly 101; Step two, start the air pump and the servo motor 401, so that the pretreatment tank 2 rotates, and a spiral gas flow appears in the pretreatment tank 2; Step three, the wave ring 5 rotates to continuously cut the basalt fibers discharged from the feeding port 302 by the cutter 705; Step four, the cut basalt fibers in segments are blown away by the spiral gas flow, and then discharged through the discharge end of the pretreatment tank 2, so as to enter the stirring assembly 101; Step five, through the stirring assembly 101, the raw materials and basalt fiber are mixed together to obtain the concrete reinforced mixed material.

[0037] At this time, the basalt fiber to be treated is fed from the feeding port 302, the driving motor of the feeding roller 303 is started, the feeding roller 303 stably and uniformly feeds the fiber downward at a set speed, so that the fiber is suspended above the two sets of cutting knives 705, and other matrix materials such as cement, aggregate, and additive required to be mixed with the basalt fiber are pre-placed in the stirring assembly 101 located at the lower part of the device according to the formula requirements.

[0038] The air pump connected to the air inlet 301 is started, high-pressure gas is continuously injected into the pretreatment tank 2, the servo motor 401 on the support 1 is started, the power of the servo motor 401 is transmitted through the gear part 402 and the tooth ring 403 fixed on the outer wall of the pretreatment tank 2, and the pretreatment tank 2 starts to rotate stably around the central axis. With the rotation of the pretreatment tank 2, the spiral blade 201 in the pretreatment tank 2 acts on the airflow, guiding and shaping the originally disordered airflow into a stable spiral upward airflow.

[0039] The rotation of the pretreatment tank 2 drives the wave ring 5 on the inner wall thereof to move synchronously in a circular motion. Since the end portions of the sliding rod 701 and the piston cylinder 601 are always in close contact with the surface of the wave ring 5 under the action of the spring part 703, the rotation of the wave ring 5 causes the wave-shaped surface thereof to periodically push and release the end portions of the sliding rod 701 and the piston cylinder 601. The reciprocating motion of the sliding rod 701 drives the cutting knives 705 at the lower end thereof to perform synchronous transverse shearing motion. The two sets of cutting knives 705 cooperate to cut the basalt fiber hanging downward from above into short fiber segments of a set length. At the same time, the piston rod of the piston cylinder 601 also performs reciprocating extension and retraction under the drive of the wave ring 5 to spray high-pressure airflow from the nozzle 603 to the cutting edge of the cutting knife 705. This airflow can effectively blow away the fiber debris adhering to the cutting edge, prevent the cutting edge from being contaminated with fiber, and ensure the continuity and efficiency of the cutting.

[0040] The well-dispersed basalt fiber finally falls into the stirring assembly 101 below through the discharge port at the bottom of the pretreatment tank 2.

[0041] The stirring assembly 101 performs high-speed and sufficient stirring and mixing of the newly added and dispersed short-cut basalt fiber and the matrix material pre-placed in the tank. After a set time of stirring, a concrete reinforced mixed material with uniform and stable performance can be obtained.

[0042] The above merely describes the preferred embodiments of the present application, and is not intended to limit the present application in any form. Although the present application has been disclosed with the preferred embodiments as above, it is not intended to limit the present application, and any skilled person in the art can make some changes or modifications to the above-mentioned technical content with the prompt as equivalent embodiments of equivalent changes without departing from the technical solution of the present application. Any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present application, which does not depart from the technical solution of the present application, still belongs to the scope of the present application.
