Description

Technical Field

[0001] The present invention relates to the technical field of water-soluble fertilizer production, and in particular to an intelligent dust removal device and method for water-soluble fertilizer production. Background Art

[0002] Water-soluble fertilizer is a type of fertilizer that can be completely dissolved in water and is made up of major nutrients such as nitrogen, phosphorus, and potassium, supplemented by some trace elements. During production, water-soluble fertilizer will generate a large amount of dust that fills the workshop. In order to avoid direct dust emissions and cause air pollution, dust removal equipment is usually used to remove the dust.

[0003] Existing dust removal devices use a variety of methods to achieve dust removal processing, such as the intelligent water circulation dust removal device for organic-inorganic compound fertilizer with publication number CN210097241U, which includes a workbench, a mixing box is installed on one side of the top of the workbench, a crushing box is provided on the top of the mixing box, an electric telescopic frame is provided on one side of the top of the crushing box, a support plate is installed on the top of the electric telescopic frame, a dust suction pipe is provided at the bottom of the support plate, a first dust suction hood and a second dust suction hood are provided at the bottom of the dust suction pipe, one end of the dust suction pipe is connected to the air inlet of the air pump through an air guide pipe, the air outlet of the air pump is connected to the upper end of one side of the dust removal box through the air guide pipe, a water spray pipe is provided in the dust removal box, a plurality of nozzles are provided on the top of the water spray pipe, a filter is provided on the lower side of the water spray pipe, a water pump is provided at the bottom of the dust removal box, and the water outlet of the water pump is connected to one end of the water spray pipe through a connecting pipe.

[0004] Existing dust removal devices usually only use an air pump adsorption method to absorb dust in the air. This dust adsorption method cannot screen the dust. The adsorbed dust is mixed with impurities, and the recycling of useful substances in the dust cannot be achieved. For example, the above-mentioned prior art uses an air pump and a dust hood to directly suck the dust into the dust hood for collection, but does not screen the dust and dust in the dust hood, and cannot achieve the recycling collection and reuse of the dust. At the same time, the spraying method cannot achieve the secondary separation of dust and sewage after dust settling, resulting in dust and water mixing into sludge, which is more difficult to clean, and has certain limitations.

[0005] Therefore, there is an urgent need to design an intelligent dust removal device and method for water-soluble fertilizer production to solve the above problems. Summary of the Invention

DETAILED DESCRIPTION

[0052] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0053] Example 1: Reference Figures 1-6 An intelligent dust removal device for water-soluble fertilizer production includes a dust removal box 2 for removing air dust in a water-soluble fertilizer production workshop. A support frame 1 for improving placement stability is provided at the lower part of the dust removal box 2, and a plurality of universal wheels for easy movement are provided at the lower part of the support frame 1.

[0054] Through the cooperation of the universal wheel and the support frame 1, the dust removal box 2 can be moved to any position in the water-soluble fertilizer production workshop, thereby realizing full-range intelligent dust removal in the production workshop, effectively improving the dust removal range and dust removal efficiency.

[0055] The dust removal device also includes:

[0056] The support plate 11 and the partition plate 12 are arranged in the dust removal box 2 to play a supporting role. The support plate 11 and the partition plate 12 are used to improve the internal structural stability of the dust removal device and achieve stable dust removal.

[0057] A servo motor 9 for driving is provided on the support plate 11 , and a driving roller 18 is fixedly mounted on the driving end of the servo motor 9 . The rotation direction and rotation speed of the driving roller 18 can be controlled by the servo motor 9 to achieve intelligent control.

[0058] The coarse filtration unit is arranged on the support plate 11 and is used to realize the adsorption, filtration and conduction of air containing dust and dirt in the water-soluble fertilizer production workshop, and is used to realize the filtration and adsorption of dust, so that the recyclable fertilizer dust is separated from the dust, thereby realizing the recycling and reuse of the dust, and at the same time, the dust is guided out for further processing.

[0059] The filter press unit is arranged on the partition plate 12 and is used to realize the atomization and flocculation treatment of dust, so that the dust and water droplets are combined and precipitated, thereby realizing the separation of dust and air, thereby realizing air purification. At the same time, the condensed dust with moisture (i.e. sludge) can be subjected to filter press treatment to fully squeeze out the water from the sludge, thereby reducing the difficulty of subsequent sludge treatment.

[0060] An intelligent control panel 3 is provided outside the dust removal box 2, which is used to control the opening and closing and operating status of the servo motor 9, the coarse filter unit, and the filter press unit to achieve intelligent dust removal;

[0061] An intelligent sensor that cooperates with the servo motor 9 is provided in the dust removal box 2, and the intelligent sensor cooperates with the intelligent control panel 3. The progress of the dust removal process inside the dust removal box 2 is automatically monitored by the intelligent sensor, and the dust removal process is synchronously fed back to the intelligent control panel 3. The intelligent control panel 3 can automatically control the efficiency and range of dust removal through the intelligent sensor, thereby realizing automatic and intelligent dust removal of fertilizer dust, and the dust removal efficiency is also higher.

[0062] Example 2: Reference Figure 2-Figure 9 The technical solution of this embodiment is different from that of the first embodiment in that the coarse filtration unit includes an air guide assembly and a filter assembly. The air guide assembly cooperates with the servo motor 9 to suck dust into the filter assembly. The filter assembly is provided with a filter plate 1 35, a filter plate 21, and an inclined filter plate 36 for achieving multi-stage dust filtration.

[0063] The air guide assembly includes a dust filter box 10 fixedly mounted on a support plate 11, and a dust suction pipe 4 for absorbing dust is fixedly connected between the dust filter box 10 and the dust removal box 2. An air guide cylinder 14 is fixedly connected to the dust filter box 10, and the air guide cylinder 14 is rotatably connected to a drive roller 18. A plurality of impellers 20 are fixedly mounted on the drive roller 18, and the plurality of impellers 20 are all located within the air guide cylinder 14.

[0064] When handling dust in the workshop, the servo motor 9 is first started to drive the driving roller 18 to rotate forward. When the driving roller 18 rotates forward, it drives the multiple impellers 20 to rotate forward. The multiple impellers 20 rotate forward, which generates negative pressure suction in the air guide cylinder 14. The air in the workshop can be sucked into the dust filter box 10 through the dust suction pipe 4, completing the air adsorption and conduction.

[0065] The workshop air contains soluble fertilizer dust, dust impurities, etc., among which the particle volume of dust is larger than the particle size of dust impurities.

[0066] In a further embodiment, the filter assembly includes a support inclined plate fixedly mounted in the dust filter box 10, and a filter plate 1 35 and a filter plate 2 21 for implementing dust filtration are fixedly mounted between the support inclined plate and the dust filter box 10, and an inclined filter plate 36 for performing dust re-filtration is fixedly mounted on the support inclined plate;

[0067] After the air enters the dust filter box 10, it will pass through the filter plate 1 35, the filter plate 2 21, and the inclined filter plate 36 in sequence and then enter the air guide cylinder 14. At this time, the filter plate 1 35, the filter plate 2 21, and the inclined filter plate 36 will perform graded filtration on the air, thereby filtering out the larger dust in the air and separating the dust from the dust. After the filtration is completed, the dust will accumulate on the filter plate 1 35, the filter plate 2 21, and the inclined filter plate 36, and the dust will flow with the air into the air guide cylinder 14, thereby completing the automatic screening of dust and dust, and realizing the independent recovery of dust.

[0068] A dust exhaust square pipe 7 for discharging dust is fixedly connected between the dust filter box 10 and the dust removal box 2 (the dust suction pipe 4 is in a closed state at this time). When the air adsorption is completed, the servo motor 9 can be started to drive the drive roller 18 to rotate in the opposite direction. When the drive roller 18 rotates in the opposite direction, it will drive multiple impellers 20 to rotate in the opposite direction. When multiple impellers 20 rotate in the opposite direction, wind airflow will be generated. After entering the dust filter box 10, the wind airflow will blow the water-soluble fertilizer dust accumulated on the filter plate 1 35, the filter plate 2 21, and the inclined filter plate 36 therein, so that the dust is discharged through the dust exhaust square pipe 7. At this time, the dust can be recovered through the dust exhaust square pipe 7 to realize the recycling and reuse of dust in the air.

[0069] The air guide cylinder 14 is provided with an air injection mechanism, which includes a dust guide elbow 17 fixedly connected to the air guide cylinder 14 for guiding the dust gas. The dust guide elbow 17 is fixedly connected to a dust box 16, and the dust box 16 is fixedly connected to multiple dust boxes.

[0070] The air and dust entering the air guide cylinder 14 will pass through the dust guide elbow 17, and after passing through the dust box 16, they will be dispersed and sprayed between the support plate 11 and the partition plate 12 through multiple dust boxes, thereby completing the air dust conduction and dispersion, making subsequent dust processing more convenient.

[0071] Example 3: Refer to 2- Figure 5 as well as Figure 10-15The technical solution of this embodiment is different from that of the second embodiment in that: the filter press unit includes a spray assembly and a filter press assembly, a water tank 15 for storing cleaning water is provided on the partition plate 12, the spray assembly cooperates with the servo motor 9 to intermittently spray the cleaning water in the water tank 15 into the dust removal box 2 in a mist form, so as to realize the condensation and sedimentation of the dust, and the filter press assembly is provided with a filter press mesh plate 34 for realizing the separation of dust and sewage after sedimentation.

[0072] The spray assembly includes a central partition 13 fixedly mounted between the support plate 11 and the partition plate 12, and a water storage tank 15 and a dust collecting box 16 are respectively located on the left and right sides of the central partition 13. A linkage roller 27 is rotatably mounted between the central partition 13 and the inner wall of the dust collecting box 2, and a linkage mechanism is installed between the linkage roller 27 and the driving roller 18.

[0073] The linkage mechanism includes a one-way bearing 19 fixedly mounted on the driving roller 18, and the one-way bearing 19 cooperates with the positive rotation of the driving roller 18. A driving wheel is fixedly mounted on the one-way bearing 19, and a driven wheel is fixedly mounted on the linkage roller 27, and a transmission belt 28 is sleeved between the driving wheel and the driven wheel.

[0074] When the servo motor 9 drives the driving roller 18 to rotate forward, the forward rotation of the driving roller 18 will drive the one-way bearing 19 to rotate (when the driving roller 18 rotates in the reverse direction to blow and collect dust, the one-way bearing 19 will not rotate at this time). The rotation of the one-way bearing 19 will drive the driving wheel thereon to rotate. The rotation of the driving wheel will drive the driven wheel to rotate with the cooperation of the transmission belt 28, and then drive the linkage roller 27 to rotate together to realize the transmission.

[0075] A lifting water squeezing plate 30 for squeezing water is slidably mounted in the water storage tank 15, and a plurality of reset spring frames 31 for resetting are fixedly mounted between the upper portion of the lifting water squeezing plate 30 and the water storage tank 15. A reciprocating cam 29 is fixedly mounted on the linkage roller 27, and an extrusion arc groove is formed on the lifting water squeezing plate 30 to cooperate with the reciprocating cam 29.

[0076] When the linkage roller 27 rotates, it drives the reciprocating cam 29 on it to rotate. When the reciprocating cam 29 rotates downward until it contacts the extrusion arc groove, it pushes the extrusion arc groove and the lifting water squeezing plate 30 downward during the downward rotation. When the lifting water squeezing plate 30 moves downward, it stretches the reset spring frame 31. When the reciprocating cam 29 rotates to separate from the lifting water squeezing plate 30, the lifting water squeezing plate 30 will move up and reset under the reset action of the reset spring frame 31. The uninterrupted rotation of the reciprocating cam 29 will repeat the above steps, thereby realizing the reciprocating lifting and lowering motion of the lifting water squeezing plate 30.

[0077] A water supply elbow 26 for guiding water is fixedly connected between the water storage tank 15 and the middle partition 13, and a spray box 23 for spraying water mist is fixedly connected to the water outlet end of the water supply elbow 26. A water supply pipe 8 for replenishing water is provided on the water storage tank 15. The water supply pipe 8 can replenish the cleaning water in the water storage tank 15 at any time, so that the water supply elbow 26 can always squeeze out cleaning water.

[0078] When the lifting water squeezing plate 30 moves downward, it squeezes the cleaning water in the water storage tank 15 and allows the cleaning water to enter the spray box 23 through the upper water elbow 26. The cleaning water is converted into mist by the spray box 23 and sprayed between the support plate 11, the partition plate 12 and the middle partition 13 in the dust removal box 2. The mist contacts the dust-laden air. When the mist cleaning water contacts the dust, the dust condenses on the water mist and settles, thereby purifying the dust in the air.

[0079] An exhaust pipe is provided in the dust removal box 2, and the air after dust settling will be discharged to the outside of the dust removal box 2 through the exhaust pipe. The air discharged at this time is clean air without dust and dirt, ensuring that it will not cause pollution to the atmosphere.

[0080] In a further embodiment, the filter press assembly includes a conduction frame 33 fixedly mounted on the partition plate 12, and a dirt collecting box 6 for collecting condensed impurities is slidably mounted on the conduction frame 33, and a water retaining side plate 22 for retaining water is fixedly mounted on the side of the dust removal box 2, and a plurality of water diversion grooves 24 for guiding water flow are opened on the water retaining side plate 22, and the lower ends of the plurality of water diversion grooves 24 are all matched with the dirt collecting box 6;

[0081] The dust mixed with the water mist is collectively named condensed impurities. The condensed impurities will move under the impact of the water mist and hit the water retaining side plate 22, and will slide downward under the guidance of the multiple water guide grooves 24 on the water retaining side plate 22 and fall into the dirt collecting box 6, thereby completing the guidance and automatic collection of the condensed impurities, avoiding the accumulation of condensed impurities and affecting the subsequent collection effect.

[0082] The dust removal box 2 is provided with an extrusion mechanism, which includes two linkage frames 32 slidably mounted on the middle partition 13, and the ends of the two linkage frames 32 are fixedly mounted on the lifting water squeezing plate 30, and the two linkage frames 32 are fixedly mounted with a water pressure plate 25 for squeezing condensed impurities;

[0083] The two linkage frames 32 are both arranged on the lifting water squeezing plate 30, and can move up and down with the lifting of the lifting water squeezing plate 30. When the linkage frame 32 moves up and down, it will drive the water pressure plate 25 to move up and down synchronously. When the water pressure plate 25 moves down, it will be pressed into the sewage collecting box 6, and the condensed impurities in the sewage collecting box 6 can be squeezed back and forth, and then the sewage in the condensed impurities can be squeezed out, completing the automatic separation of sewage and dust, which can effectively prevent the sewage from mixing into sludge and being difficult to clean, and effectively reduce the difficulty of cleaning and collecting condensed impurities.

[0084] A filter press plate 34 for squeezing water is fixedly installed on the dirt collecting box 6, and a sewage pipe 5 for discharging sewage is provided at the bottom of the dust removal box 2. After the condensed impurities are squeezed by the water pressure plate 25, the sewage inside will fall to the bottom of the dust removal box 2 through the filter press plate 34 and the conduction frame 33, and can be directly discharged through the sewage pipe 5. After the condensed impurities in the dirt collecting box 6 are filtered, the dirt collecting box 6 can be directly pulled out of the dust removal box 2 to clean the condensed impurities in the dirt collecting box 6.

[0085] The specific working principle of this dust removal device is:

[0086] When handling dust in the workshop, the servo motor 9 is first started to drive the drive roller 18 to rotate forward. When the drive roller 18 rotates forward, it will drive the multiple impellers 20 to rotate forward. The multiple impellers 20 rotate forward, which will generate negative pressure suction in the air guide cylinder 14. The air in the workshop can be sucked into the dust filter box 10 through the dust suction pipe 4.

[0087] After entering the dust filter box 10, the air will pass through the filter plate 1 35, the filter plate 2 21, and the inclined filter plate 36 in sequence before entering the air guide cylinder 14. At this time, the filter plate 1 35, the filter plate 2 21, and the inclined filter plate 36 will filter the air in stages, thereby filtering out the larger dust in the air and separating the dust from the dust.

[0088] After filtering, the dust will accumulate on filter plate 1 35, filter plate 2 21, and inclined filter plate 36, and the dust will flow into the air guide cylinder 14 with the air, thereby completing the automatic screening of dust and dust. The air and dust entering the air guide cylinder 14 will pass through the dust guide elbow 17, and after passing through the dust box 16, they will be dispersed and sprayed between the support plate 11 and the partition plate 12 through multiple dust boxes, thereby completing the air dust conduction and dispersion.

[0089] The positive rotation of the driving roller 18 drives the one-way bearing 19 to rotate. The rotation of the one-way bearing 19 drives the driving wheel on it to rotate. The rotation of the driving wheel drives the driven wheel to rotate with the cooperation of the transmission belt 28, and then drives the linkage roller 27 to rotate together. The rotation of the linkage roller 27 drives the reciprocating cam 29 to rotate. When the reciprocating cam 29 rotates and acts together with the return spring frame 31, the reciprocating lifting and lowering motion of the water squeezing plate 30 is realized.

[0090] When the lifting water squeezing plate 30 moves downward, it will squeeze the cleaning water in the water storage tank 15, and make the cleaning water enter the spray box 23 through the water supply elbow 26. The cleaning water is converted into mist by the conversion action of the spray box 23 and sprayed between the support plate 11, the partition plate 12 and the middle partition 13 in the dust removal box 2, and will come into contact with the downward dust-laden air. At this time, when the mist cleaning water comes into contact with the dust, the dust will condense and settle on the water mist, thereby achieving the purification of the dust in the air.

[0091] The condensed impurities will move under the impact of the water mist and hit the water retaining side plate 22, and will slide downward under the diversion effect of the multiple water guide grooves 24 on the water retaining side plate 22 and fall into the sewage collecting box 6, thus completing the guidance and automatic collection of the condensed impurities. When the linkage frame 32 moves up and down, it will drive the water pressure plate 25 to move up and down synchronously. When the water pressure plate 25 moves down, it will be pressed into the sewage collecting box 6, and the condensed impurities in the sewage collecting box 6 can be reciprocated and squeezed, thereby squeezing out the sewage in the condensed impurities, completing the automatic separation of sewage and dust.

[0092] After the condensed impurities are squeezed by the water pressure plate 25, the sewage inside will fall to the bottom of the dust removal box 2 through the filter press mesh plate 34 and the conduction frame 33, and the sewage can be directly discharged through the sewage pipe 5. After the condensed impurities in the sewage collecting box 6 are filtered, the sewage collecting box 6 can be directly pulled out of the dust removal box 2 to clean the condensed impurities in the sewage collecting box 6.

[0093] The embodiment of the present invention further provides an intelligent dust removal method for water-soluble fertilizer production, which is used in the above-mentioned intelligent dust removal device for water-soluble fertilizer production, and includes the following steps:

[0094] S1. The air dust in the water-soluble fertilizer production workshop is sucked into the filter component through the air guide component in the coarse filter unit;

[0095] S2. Through the cooperation of the filter plate 1 35, the filter plate 2 21 and the inclined filter plate 36 in the filter assembly, large-volume impurities in the dust are filtered out to achieve coarse filtration of the dust;

[0096] S3. The air dust after coarse filtration is passed into the lower part of the support plate 11 through the air guide component, and water mist is sprayed through the spray component to mix and condense the water mist with the small dust particles in the air to achieve secondary treatment of the dust;

[0097] S4. The condensed dust is precipitated into condensed impurities, which are squeezed and filtered through the filter press assembly to squeeze out the sewage in the condensed impurities, thereby achieving filter press separation of sewage and dust impurities and completing the re-treatment of the dust.

[0098] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
