Description

Technical Field

[0001] The invention belongs to the technical field of soil remediation agent raw material crushing, and specifically refers to a raw material crushing device for preparing a composite soil remediation agent. Background Art

[0002] Soil remediation improver is a new type of biological strain in the form of powder. It has the characteristics of rapid reproduction, strong vitality, safety and non-toxicity, high temperature resistance, no inactivation during granulation and drying, and long-term preservation. It has the effect of improving soil structure. The composite soil remediation agent is mainly composed of biomass and microbial strains. The biomass can be selected from straw, bran, sawdust, etc., and the microbial strains can be selected from a variety of fast-acting bacteria, medium-acting bacteria and slow-acting bacteria. When preparing the composite soil remediation agent, a crushing device is required to crush the biomass raw materials to facilitate the subsequent granulation. However, the existing crushing device crushes the raw materials by squeezing and cutting the cutting structure to each other. Impurities such as hard stones mixed in the raw materials cannot be screened out during crushing, which can easily cause damage to the cutter and affect the crushing efficiency. In addition, different biomass raw materials have different shapes and are difficult to process at the same time. The segmented raw materials are easily stuck on the cutting structure, resulting in low crushing efficiency and uneven crushing, which reduces the preparation efficiency of the composite soil remediation agent. Summary of the invention

Before the biomass raw material is crushed, the straw and the bran are preferentially separated and processed to remove hard stones in the raw materials, avoid damage to the cutter, and improve the service life. After the straw is cut into segments, it falls into the two-way cutting pulverizing component together with the bran for pulverization. The first pulverizing knife, the second pulverizing knife and the third pulverizing knife arranged vertically and staggered can cut the segmented raw materials in two directions, and the pulverizing efficiency is high, which is helpful to improve the reaction efficiency in the subsequent preparation of the composite soil remediation agent.

Separation wheels are symmetrically provided at both ends of the squeezing roller through the primary processing cover shell, and separation screen holes are evenly distributed on the outer wall of the separation roller. The squeezing roller drives the separation roller to rotate through the meshing transmission teeth and follower teeth.

[0006] Further, the air selection mechanism comprises a fan, a receiving arc plate, a first air duct and a second air duct, the fan being arranged on the outer side wall of a primary processing housing, the receiving arc plate being connected to the inner wall of the primary processing housing, the outer wall of the receiving arc plate being slidably fitted with the inner wall of the separation roller, the arc length of the cross section of the receiving arc plate being greater than 180 degrees, the end of the receiving arc plate close to the conveying frame being higher than the end thereof away from the conveying frame, the inner bottom surface of the receiving arc plate being a plane, the bottom of the receiving arc plate being evenly embedded with first blowing ports, the first air duct and the second air duct being respectively connected with the output end of the fan, the first air duct being embedded in the bottom of the receiving arc plate, the first air duct being connected with the first blowing port, the second air duct being arranged on the inner side of the receiving arc plate close to the conveying frame, the second air duct being evenly distributed with second blowing ports along the axial direction, the second blowing port being directed toward the upper side of the end of the receiving arc plate away from the conveying frame;

[0007] When in use, granular bran, broken materials and stones fall onto the separation roller and fall onto the receiving arc plate in the separation roller through the separation sieve holes. At this time, the fan starts to blow air into the first air duct and the second air duct. The first air outlet blows air upward to blow up the lighter bran and broken materials that fall into the receiving arc plate, while the heavier hard stones cannot be blown up and fall to the bottom of the receiving arc plate. The technical effect of separating the hard stones from the raw materials is achieved through air selection. The blown bran and broken materials are further blown by the wind flow blown out of the second air outlet to the upper side of the receiving arc plate away from the conveying frame, and are blown out from the separation sieve holes.

[0010] During use, the long pole-shaped straw will be inserted between the squeezing roller and the separating roller under the rotation of the separating roller, and will continue to be transported to the primary cutting support plate under the rotation and squeezing of the squeezing roller and the separating roller. The separating wheels on both sides of the squeezing roller drive the cutter wheel to rotate through the second transmission belt, thereby causing the power rod to rotate in the movable groove. Since the power rod and the cutter wheel are eccentrically arranged, the power rod as a whole makes a circular motion in the movable groove. During the movement of the power rod, the cutter is driven to move through the pulling plate, and the cutter moves up and down in the limiting groove under the restriction of the limiting groove, thereby cyclically cutting the straw transported to the primary cutting support plate. Since the diameter ratio of the separating wheel and the cutter wheel is four to one, the squeezing roller rotates one circle and the cutter cuts four times, thereby preliminarily cutting the long pole-shaped straw into small sections, which fall into the crushing cover under the action of gravity.

The comb teeth on the combing roller comb the raw material and control the amount of raw material passing through to avoid accumulation caused by excessive raw material being transported at the same time.

[0013] Furthermore, a separation arc plate is provided at the end of the conveying frame away from the feeding port, and the central angle of the separation arc plate is equal to the central angle of the receiving arc plate. The separation roller is rotatably arranged on the inner side of the separation arc plate, and the outer wall of the separation roller slides and fits with the inner wall of the separation arc plate. The end of the separation arc plate away from the conveying frame, the end of the receiving arc plate away from the conveying frame and the central rotating axis of the separation roller are in the same plane, the upper end surface of the conveying belt is higher than the separation arc plate, and the upper end section of the separation roller is in the same plane as the upper end surface of the conveying belt. A scraper plate is provided on the upper part of the end of the separation arc plate close to the conveying frame, and one end of the scraper plate is overlapped on the conveying belt. A cleaning door is rotatably provided at the rear of the separation arc plate for recovering impurities such as hard stones that have been screened out.

[0014] Furthermore, the bidirectional cutting type pulverizing assembly comprises a pulverizing cover, a material baffle plate, a sliding plate, a main rotating column, a first pulverizing knife, a second pulverizing knife and a third pulverizing knife, the pulverizing cover is cylindrical, the pulverizing cover is horizontally connected to the lower part of the primary processing cover away from the conveying frame, the side of the pulverizing cover away from the conveying frame is provided with a supporting leg, the lower part of the pulverizing cover is provided with a screen, the discharging tray is arranged below the screen, the upper part of the pulverizing cover is connected with a material receiving shell, the material receiving shell is communicated with the primary processing cover, the material baffle plate is provided with a main rotating column, the first pulverizing knife is connected with the second pulverizing knife and the third pulverizing knife, the pulverizing cover is cylindrical, the pulverizing cover is horizontally connected to the lower part of the primary processing cover away from the conveying frame, the side of the pulverizing cover away from the conveying frame is provided with a supporting leg, the lower part of the pulverizing cover is provided with a screen, the discharging tray is provided below the screen, the upper part of the pulverizing cover is connected with a material receiving shell, the material receiving shell is communicated with the primary processing cover, The plate is tilted in the primary processing housing, the baffle plate is connected to the side of the primary cutting support plate away from the squeezing roller, the sliding plate is tilted below the baffle plate, the sliding plate is connected between the separation arc plate and the crushing housing, the side wall of the receiving housing away from the primary processing housing is in a vertical state, the bran and crushed materials blown out from the separation sieve hole are blown to the primary cutting support plate and the baffle plate, the tilted baffle plate guides the airflow into the receiving housing and flows toward the crushing housing, and the blown bran and crushed materials fall into the crushing housing under the action of the airflow and their own gravity;

[0015] Furthermore, the main rotating column is horizontally rotated and arranged at the center of the crushing cover, the main rotating column is driven by a crushing motor, the first crushing knives are uniformly distributed on the inner wall of the crushing cover, the second crushing knives are uniformly distributed on the outer wall of the main rotating column, the first crushing knives and the second crushing knives are respectively arranged in an array along the axis direction of the main rotating shaft, the first crushing knives and the second crushing knives are arranged alternately, the third crushing knives are arranged in an array on the second crushing knives along the radial direction of the crushing cover, the third crushing knives are perpendicular to the second crushing knives, the third crushing knives adjacent to each other along the axial direction of the main rotating shaft are arranged axially symmetrically with the first crushing knives as the axis, and the outer wall of the outermost third crushing knife is slidably fitted with the inner wall of the crushing cover;

[0016] When in use, the main rotating column rotates to drive the second crushing knife to rotate. The first crushing knife is fixed on the inner wall of the crushing cover, the second crushing knife and the first crushing knife are arranged alternately, and the third crushing knife is perpendicular to the second crushing knife. Under the high-speed rotation of the main rotating column, small pieces of straw and bran and other raw materials falling into the crushing cover are cut and crushed by the first crushing knife, the second crushing knife and the third crushing knife arranged horizontally and vertically. After the crushing, the raw materials fall into the discharge tray through the screen at the bottom of the crushing cover. Since the outer wall of the outermost third crushing knife slides and fits with the inner wall of the crushing cover, when the outermost third crushing knife rotates and slides over the position of the screen, the raw materials stuck on the screen or not completely crushed are scraped and lifted up again, and the raw material fragments lifted or driven by the third crushing knife are cut off again when they rotate and pass through the first crushing knife, thereby improving the raw material crushing efficiency. In this process, when the second crushing knife and the third crushing knife rotate, the first crushing knife continuously passes through the adjacent third crushing knives to cut off the raw material blocks therebetween, so as to avoid small pieces of raw materials being stuck between the first crushing knife, the second crushing knife or the third crushing knife.

[0017] Furthermore, the pressure-driven crushing mechanism includes a pressure-driven cover, a pressure-driven motor, a pressure-driven block, a connecting plate and a power rotating plate, the pressure-driven cover is connected to the upper part of the conveying frame, the pressure-driven cover is arranged between the feeding port and the initial processing cover, the pressure-driven motor is arranged on the side wall of the pressure-driven cover, the pressure-driven block is slidably arranged on the inner side of the conveying frame, the connecting plate is arranged on the upper part of the pressure-driven block, the connecting plate is slidably arranged on the inner side of the pressure-driven cover, a waist-shaped groove is horizontally penetrated on the connecting plate, the power rotating plate is rotatably arranged on the inner side of the pressure-driven cover, the power rotating plate is connected to the output end of the pressure-driven motor, the power rotating plate is a waist-shaped structure, a driving column is arranged at the rotating end of the power rotating plate, the driving column deviates from the rotation center of the power rotating plate, the driving column is slidably arranged in the waist-shaped groove, and the pressure block is concave toward the bottom surface of the conveyor belt. Uneven; when the raw materials are transported to the compression crushing mechanism, the compression motor drives the power turn plate to rotate, and the driving column at the rotating end thereof rotates accordingly, thereby driving the connecting plate to move up and down in the compression cover. During this period, the driving column slides adaptively in the waist-shaped groove, and the up and down movement of the connecting plate drives the compression block to move up and down. The pressure plate serves as a fixed supporting surface to support the stable transportation of the raw materials. The compression block with an uneven bottom surface continuously impacts and squeezes the raw materials above the pressure plate, and initially crushes and flattens the rod-shaped straw, and at the same time shakes out the hard stones mixed in the straw or bran. Since the conveyor belt is soft in texture and has a certain elasticity, the hard stones are difficult to be crushed by the compression block. Then the scraper plate jointly transports the initially crushed and flattened straw, bran and the initially separated hard stones to the separation-type primary crushing processing component.

[0018] The beneficial effects achieved by the present invention using the above structure are as follows:

[0019] 1. The raw material crushing device for preparing a composite soil remediation agent provided by the present invention adopts the pre-action principle, combines the shape characteristics of straw and the light weight of bran, and sets a separation type primary crushing processing component. Before the biomass raw material is crushed, the straw and bran are preferentially separated and processed, and the technical effect of separating and removing hard stones from the raw material is achieved through air selection, thereby avoiding damage to the cutter and improving the service life;

[0020] 2. The initial cutting mechanism cuts the straw into segments, and then the straw and the bran fall into the two-way cutting crushing assembly for crushing. The first crushing knife, the second crushing knife and the third crushing knife arranged vertically and staggered can cut the segmented raw materials in two directions, and when the outermost third crushing knife rotates and slides over the position of the screen, the raw materials stuck on the screen or not completely crushed are scraped and lifted up again, and the raw material fragments lifted or driven by the third crushing knife are cut off again when they rotate through the first crushing knife, thereby improving the raw material crushing efficiency. In this process, when the second crushing knife and the third crushing knife rotate, the first crushing knife continuously passes between the adjacent third crushing knives to cut off the raw material blocks therebetween, so as to avoid small segments of raw materials being stuck between the first crushing knife, the second crushing knife or the third crushing knife. The crushing efficiency is high, which is helpful to improve the reaction efficiency in the subsequent preparation of the composite soil remediation agent;

[0021] 3. A pressure crushing mechanism is set up. The uneven pressure block on the bottom continuously impacts and squeezes the raw materials, initially crushing and flattening the rod-shaped straw, and at the same time shaking out the hard stones mixed in the straw or bran, which is convenient for the subsequent screening of hard stones and the cutting of long rod-shaped straw;

[0022] 4. When the raw materials move through the combing rollers, the raw materials accumulated on the upper part are blocked by the combing rollers. The comb teeth on the combing rollers comb the raw materials and control the amount of raw materials passing through to avoid accumulation caused by excessive raw materials being transported at the same time.

[0046] Working principle and workflow:

[0047] When used specifically, a mixed biomass such as straw and bran is used as a raw material. The straw is in the shape of a long rod and has a certain toughness, and the bran is light in weight. The straw and bran mixture is put into the feed port 5. Under the action of gravity, the raw material falls onto the conveyor belt 13, and the main power motor 111 is started. The main power motor 111 drives the active rotary wheel 11 to rotate, and drives the driven rotary wheel 12 to rotate through the conveyor belt 13. At the same time, the transmission wheel disc 17 drives the driven wheel disc 19 to rotate through the first transmission belt 110, so that the combing roller 18 rotates clockwise, and the conveyor belt 13 transports the raw materials thereon to move. When passing through the combing roller 18, the raw materials accumulated on the upper part are blocked by the combing roller 18, and the comb teeth on the combing roller 18 comb the raw materials and control the amount of raw materials passing through, so as to avoid accumulation caused by too much raw materials being transported at the same time;

[0048] When the raw material is transported to the compression crushing mechanism 4, the compression motor 44 is started, driving the power turn plate 46 to rotate, and the driving column 47 at its rotating end rotates accordingly, thereby driving the connecting plate 43 to move up and down in the compression cover 41. During this period, the driving column 47 slides adaptively in the waist-shaped groove 45, and the up and down movement of the connecting plate 43 drives the compression block 42 to move up and down. The pressure plate 14 serves as a fixed supporting surface to support the stable transportation of the raw material. The compression block 42 with an uneven bottom surface continuously impacts and squeezes the raw material above the pressure plate 14, initially crushing and flattening the rod-shaped straw, and at the same time shaking out the hard stones mixed in the straw or bran. Since the conveyor belt 13 is soft in texture and has a certain elasticity, the hard stones are difficult to be crushed by the compression block 42. Then the scraper plate 16 transfers the initially crushed and flattened straw, bran and the initially separated hard stones to the separation type primary crushing processing component 2.

[0049] The separation motor 223 is started, and the squeeze roller 22 rotates. The squeeze roller 22 drives the separation roller 23 to rotate through the meshing transmission teeth 221 and the follower teeth 232. Since the upper end surface of the conveyor belt 13 is higher than the separation arc plate 15, and the upper end section of the separation roller 23 is in the same plane as the upper end surface of the conveyor belt 13, the scraper plate 16 is in an inclined state. The raw materials pass through the scraper plate 16, and the granular bran, crushed materials and stones fall onto the separation roller 23, and pass through the separation sieve hole 231 to fall onto the receiving arc plate 241 in the separation roller 23. At this time, the fan 246 is started to blow air into the first air duct 242 and the second air duct 243, and the first blowing port 244 blows air upward to The lighter bran and broken materials in the receiving arc plate 241 are blown up, while the heavier hard stones cannot be blown up and fall to the bottom of the receiving arc plate 241. The technical effect of separating the hard stones from the raw materials is achieved through air selection. The blown bran and broken materials are further blown to the upper side of the receiving arc plate 241 and the separation arc plate 15 away from the conveying frame 1 by the wind flow blown out by the second blowing port 245, and are blown out from the separation sieve hole 231 to the primary cutting support plate 213 and the material baffle plate 34. The inclined material baffle plate 34 guides the wind flow into the receiving shell 32 and flows toward the crushing cover shell 31. The blown bran and broken materials fall into the crushing cover shell 31 under the action of the wind flow and their own gravity.

[0050] At the same time, the long rod-shaped straw will be inserted between the squeezing roller 22 and the separating roller 23 under the rotation of the separating roller 23, and will continue to be transported to the primary cutting support plate 213 under the rotation and squeezing of the squeezing roller 22 and the separating roller 23. The separating wheels 222 on both sides of the squeezing roller 22 drive the cutter wheel 251 to rotate through the second transmission belt 224, thereby causing the power rod 252 to rotate in the movable groove 211. Since the power rod 252 and the cutter wheel 251 are eccentrically arranged, when the power rod 252 is as a whole in the movable groove 211, the power rod 252 is rotated in the movable groove 211. The cutting blade 254 moves in a circular motion inside the primary cutting support plate 213. During the movement of the power rod 252, the pulling plate 253 drives the cutting blade 254 to move. The cutting blade 254 moves up and down in the limiting groove under the restriction of the limiting groove 212, and then cyclically cuts the straw transported to the primary cutting support plate 213. Since the diameter ratio of the separating wheel 222 to the cutting blade rotating wheel 251 is four to one, the squeezing roller 22 rotates one circle, and the cutting blade 254 cuts four times, and the long rod-shaped straw is preliminarily cut into small sections, and falls into the crushing cover 31 under the action of its gravity.

[0051] The pulverizing motor 37 is started, the main rotating column 36 rotates, driving the second pulverizing blade 38 to rotate, the first pulverizing blade 312 is fixed on the inner wall of the pulverizing housing 31, the second pulverizing blade 38 is staggered with the first pulverizing blade 312, and the third pulverizing blade 39 is perpendicular to the second pulverizing blade 38. Under the high-speed rotation of the main rotating column 36, the small pieces of straw and bran and other raw materials that fall into the pulverizing housing 31 are cut and pulverized by the first pulverizing blade 312, the second pulverizing blade 38 and the third pulverizing blade 39 that are arranged horizontally and vertically. After the pulverization, the raw materials fall into the discharge tray 6 through the screen 311 at the bottom of the pulverizing housing 31. Due to the outermost third pulverizing blade 39 The outer wall is slidably fitted with the inner wall of the crushing cover 31. When the outermost third crushing knife 39 rotates and slides over the position of the screen 311, the raw materials stuck on the screen 311 or not completely crushed are scraped and lifted up again. The raw material fragments lifted or driven by the third crushing knife 39 are cut off again when they rotate and pass through the first crushing knife 312, thereby improving the raw material crushing efficiency. In this process, when the second crushing knife 38 and the third crushing knife 39 rotate, the first crushing knife 312 continuously passes between the adjacent third crushing knives 39 to cut off the raw material blocks therebetween, thereby preventing small pieces of raw materials from being stuck between the first crushing knife 312, the second crushing knife 38 or the third crushing knife 39.

[0052] After the crushing is completed, the raw material debris in the discharge tray 6 is collected, and the cleaning door on the rear side of the separation roller 23 is opened to recover the hard stones and other impurities in the receiving arc plate 241.

[0053] It is worth noting that the use of the fan 246 is all existing technology and will not be repeated here.

[0054] The above is the overall workflow of the present invention, and you can repeat this step next time you use it.
