Description

[0001] The present invention relates to the technical field of drying equipment, in particular to drying equipment for producing environmental pollution treatment agents. Background Art

[0002] In modern industrial production, the demand for environmental pollution treatment agents is increasing, especially in areas such as water treatment, air purification, and soil remediation. Drying equipment is a key link in the production process, and its performance directly affects product quality and production efficiency. Therefore, the development of efficient and energy-saving drying equipment is particularly important.

[0003] However, in the prior art, a Chinese patent with the announcement number CN208688199U discloses a disc-type multi-layer drying device, which discloses that uniform drying is achieved through the tilting movement of rakes and steam heating, and that impurities and dust are separated and recovered using screens and moisture filters to prevent blockage and waste. However, the drying disc in the comparative document adopts a circular shape, and the drying path of the material on the drying disc is a circular vortex path. The heated steam enters from one side of the drying disc and is discharged from the other side. Due to the lack of coordinated design between the steam flow direction and the material drying path, the surface temperature distribution of the drying disc is uneven, forming a temperature difference within the disc, and heat accumulation or loss in local areas, resulting in partial heat waste.

[0004] The information disclosed in the background technology section of the present invention is only intended to deepen the understanding of the general background technology of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art.

[0013] Furthermore, a sliding groove is provided on the adjustment plate, and the sliding rod is in sliding cooperation with the sliding groove. The sliding rod is guided by the sliding groove to enable the scraper to separate from the first track or the second track.

[0014] Furthermore, the scrapers rotate synchronously with the rotating shaft. When the scrapers move in the elliptical spiral track, adjacent scrapers move at differential speeds to form continuous extrusion of the material.

Furthermore, when a first feature is "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0022] Refer to the following Figures 1 to 11 The present invention provides a drying device for producing an environmental pollution treatment agent according to an embodiment of the present invention.

[0023] like Figure 1 and Figure 2 As shown, the drying equipment for producing environmental pollution treatment agents provided by the embodiment of the present invention is particularly suitable for drying environmental pollution treatment agents. Of course, it can also be used for drying treatments under other operating conditions under appropriate circumstances.

[0024] Specifically, the drying equipment for producing environmental pollution treatment agents includes a main housing 100. The main housing 100 serves as a mounting base for other components, which can be directly or indirectly mounted on the main housing 100 to form a relatively integrated whole. Furthermore, the main housing 100 is provided with a feed inlet 101 and a discharge outlet 102. The feed inlet 101 is located at the top of the main housing 100, and the discharge outlet 102 is located at the bottom.

[0025] like Figure 3 As shown, the main housing 100 is further provided with a first support plate 201 and a second support plate 202, which are coaxially spaced apart. The cross-sectional area of ​​the second support plate 202 is larger than that of the first support plate 201, and a hollow area is defined in the middle of the second support plate 202. Furthermore, a support frame 200 is further provided within the main housing 100. The support frame 200 is fixed to the interior of the main housing 100 and is used to support the first and second support plates 201, 202, to prevent displacement or damage due to vibration or other factors.

[0026] Further, if Figures 3 to 8 As shown, a spiral-shaped limiter 210 is fixedly mounted on each of the first support plate 201 and the second support plate 202. The limiter 210 and the first support plate 201 together form a first track 211, and together with the second support plate 202, a second track 212. Both the first track 211 and the second track 212 are spiral-shaped, allowing material to flow. Specifically, when material flows along the spiral-shaped first and second tracks 211 and 212, the material's residence time on the first and second support plates 201 and 202 is extended compared to a circular spiral track.

[0027] The drying equipment for producing environmental pollution treatment agents further includes a heating unit 300 , which is used to heat the first support plate 201 and the second support plate 202 , so that the materials are dried on the first support plate 201 and the second support plate 202 .

[0028] Furthermore, the drying equipment for producing environmental pollution treatment agents also includes a pusher assembly, which is used to push the material to flow between the first track 211 and the second track 212. The first track 211 and the second track 212 both have an inner end and an outer end, wherein the inner end of the second track 212 is connected to the hollow area. Specifically, when the material falls onto the first support plate 201 through the feed port 101, the pusher assembly pushes the material along the inner end of the first track 211 to the outer end of the first track 211. After the pusher assembly pushes the material to flow to the outer end of the first track 211, because the cross-sectional area of ​​the second support plate 202 is larger than that of the first support plate 201, the material falls to the outer end of the second track 212 under the push of the pusher assembly, and the pusher assembly pushes the material along the outer end of the second track 212 to the inner end of the second track 212. After the pusher assembly pushes the material to flow to the inner end of the second track 212, the material flows out of the hollow area under the action of the pusher assembly, then detaches from the second support plate 202 and is discharged from the discharge port 102.

[0029] It is understood that multiple first support trays 201 and second support trays 202 may be provided to optimize the drying effect of the material. Specifically, after being dried on the first support tray 201, the material falls from the outer end of the first track 211 to the second support tray 202 for further drying. The material then falls from the inner end of the second track 212 to the next first support tray 201, and finally falls from the inner end of the second support tray 202 at the end to the discharge port 102.

[0030] When the equipment is working, because the material is dried on the surface of the first support plate 201 and the second support plate 202, if the heat source is only charged on one side, the temperature of the heat source will gradually decrease along its flow path, resulting in uneven temperature on the surface of the first support plate 201 and the second support plate 202, that is, the temperature of the area close to the heat source is high, and the temperature of the area far from the heat source is low, thereby reducing the overall drying effect of the material.

[0031] In one embodiment, two groups of heating units 300 are provided, and the two groups of heating units 300 are evenly distributed circumferentially along the first support plate 201 and the second support plate 202. The heating units 300 include a heat inlet pipe 301 and a heat outlet pipe 313. The first support plate 201 and the second support plate 202 both have a receiving chamber 203 inside, and the heat inlet pipe 301 and the heat outlet pipe 313 are both connected to the receiving chamber 203.

[0032] Furthermore, the main housing 100 is provided with a heat source inlet 314 and a heat source outlet 315. The heat source inlet 314 is connected to the heat inlet pipe 301, and the heat outlet pipe 313 is connected to the heat source outlet 315. Specifically, when the device starts working, the heat source is introduced through the heat source inlet 314 and enters the accommodating chamber 203 from different positions through the heat inlet pipe 301, so that the heat source flows from the end to the middle, enhancing the uniform mixing of the heat source in the accommodating chamber 203 and avoiding temperature differences caused by unilateral charging. When the heat source temperature decreases or the heat source is replaced, the heat source originally in the accommodating chamber 203 is discharged from the heat source outlet 315 through the heat outlet pipe 313, and the new heat source is re-introduced through the heat source inlet 314.

[0033] In one embodiment, Figure 9As shown, a turbulent structure 320 is provided in the receiving chamber 203. A first nozzle 311 and a second nozzle 312 are provided at the end of the heat inlet pipe 301 in the receiving chamber 203. The first nozzle 311 and the second nozzle 312 are connected to the heat source inlet 314. The first nozzle 311 and the second nozzle 312 are both connected to the receiving chamber 203. Specifically, the diameter of the second nozzle 312 is larger than the diameter of the first nozzle 311. When the heat inlet pipe 301 fills the receiving chamber 203 with heat source through the first nozzle 311 and the second nozzle 312, the heat source flow rate ejected from the second nozzle 312 is greater than the heat source flow rate ejected from the first nozzle 311. Because the heat source ejected from the second nozzle 312 has a larger flow rate, the heat source flow velocity around the second nozzle 312 is faster than the heat source flow velocity around the first nozzle 311. Therefore, the heat supply rate of the second nozzle 312 is greater than the heat supply rate of the first nozzle 311, thereby creating a difference in heat supply rate between the first nozzle 311 and the second nozzle 312, generating airflow disturbances, and thereby driving the rotation of the spoiler structure 320. The rotation of the spoiler structure 320 allows the heat source ejected from the first nozzle 311 and the heat source ejected from the second nozzle 312 to be fully mixed in the receiving chamber 203, thereby evenly mixing the heat sources in the receiving chamber 203, thereby maximally evenly distributing the heat source in the receiving chamber 203, and ensuring that the first support plate 201 and the second support plate 202 are heated to uniform temperatures.

[0034] In one embodiment, Figures 7 and 8 As shown, both the first support plate 201 and the second support plate 202 are elliptical structures. The first track 211 is an elliptical spiral that matches the first support plate 201, and the second track 212 is an elliptical spiral that matches the second support plate 202. Specifically, since both the first support plate 201 and the second support plate 202 are elliptical structures, they each have a minor axis and a major axis. The heat inlet pipe 301 is located at the minor axis, and the heat outlet pipe 313 is located at the major axis.

[0035] Furthermore, the drying equipment for producing environmental pollution treatment agents further includes a rotating shaft 111 and a driving mechanism 110. Figure 3As shown, the pusher assembly includes a plurality of pusher units 400, which are arranged on the surfaces of the first support plate 201 and the second support plate 202. The driving mechanism 110 provides power to the pusher units 400 through the rotating shaft 111, which is used to push the material to flow along the first track 211 and the second track 212. Specifically, because the rotating shaft 111 rotates at a constant speed and the pusher units 400 are driven by the rotating shaft 111, the angular velocity of the material flowing on the first track 211 and the second track 212 is constant. Therefore, the linear velocity of the material flowing through the short axis end is slower than the linear velocity at the long axis position. Although the heat source in the accommodating chamber 203 has been distributed as evenly as possible, the temperature of the area closer to the heat inlet pipe 301 in the accommodating chamber 203 is higher. Therefore, when the material flows through the short axis, due to the slow speed, the residence time is longer, and the heat inlet pipe 301 is arranged at the short axis position, so the effect of being dried by high temperature is better. Therefore, by coordinating the direction of heat source flow and material flow, the drying effect of the material is enhanced and the problem of partial heat waste caused by heat accumulation or loss in local areas is optimized.

[0036] In one embodiment, Figure 5 As shown, the pusher unit 400 includes a feed rod 401, a sliding stopper 403, a scraper 408, an adjustment plate 405, and an elastic reset unit. Furthermore, the feed rod 400 also includes a stopper 402. The feed rod 401 is fixedly connected to the rotating shaft 111 at one end and to the stopper 402 at the other end. The sliding stopper 403 is slidably connected to the feed rod 401, the scraper 408 is slidably connected to the sliding stopper 403, and the adjustment plate 405 is slidably connected to the sliding stopper 403.

[0037] Further, if Figures 5 to 11 As shown, the elastic reset unit includes an elastic member 404, an adjustment plate 405, and a slide rod 407. One end of the elastic member 404 is fixedly connected to the rotating shaft 111, and the other end is fixedly connected to the sliding limit block 403. The adjustment plate 405 is slidably connected to the sliding limit block 403. One end of the slide rod 407 is slidably connected to the adjustment plate 405, and the other end is rotatably connected to the scraper 408.

[0038] In one embodiment, Figure 11As shown, a slide groove 406 is provided on the adjustment plate 405, and the slide rod 407 slides in cooperation with the slide groove 406. Specifically, when starting to work, the rotating shaft 111 drives the material-dispensing rod 401 to rotate synchronously, so that the scraper 408 pushes the material in the first track 211 and the second track 212, and drives the sliding limit block 403 to slide along the material-dispensing rod 401. When the scraper 408 on the first support plate 201 moves to the outer end of the first track 211, the adjustment plate 405 abuts against the limit block 402. At this time, the adjustment plate 405 no longer slides, forcing the slide rod 407 to slide along the slide groove 406 toward the direction close to the material-dispensing rod 401, thereby driving the scraper 408 to slide upward and separate from the first support plate 201, that is, Figure 5 Then, the elastic member 404 pulls the sliding limit block 403 to slide along the material removal rod 401 toward the inner end of the first track 211, thereby driving the scraper 408 to move and reset. When the scraper 408 of the second support plate 202 moves to the inner end of the second track 212, the adjustment plate 405 abuts against the rotating shaft 111. At this time, the adjustment plate 405 no longer slides, forcing the slide bar 407 to slide along the slide groove 406 toward the direction close to the material removal rod 401, thereby driving the scraper 408 to slide upward and separate from the second support plate 202. Then, the elastic member 404 pulls the sliding limit block 403 to slide toward the outer end of the second track 212, thereby driving the scraper 408 to move and reset.

[0039] In one embodiment, the scraper 408 rotates synchronously with the rotating shaft 111. Since the speed of the scraper 408 is constantly changing when pushing the material to flow on the elliptical spiral track, that is, the linear speed is slower when it is closer to the short axis end, and the linear speed is faster when it is closer to the long axis position, a speed difference is formed between adjacent scrapers 408, so that the adjacent scrapers 408 continuously squeeze the material due to the differential motion, thereby allowing the material to be dried in a smaller size, thereby further improving the drying efficiency.

[0040] In particular, if Figure 3 As shown, the drying equipment for producing environmental pollution treatment agents also includes a plurality of retaining plates 220, which are sequentially arranged between the first support plate 201 and the second support plate 202 and fixedly connected to the rotating shaft 111. The provision of the retaining plates 220 prevents excessive material from falling into the area close to the first support plate 201 and the rotating shaft 111. Due to the size limitation of the scraper 408, the scraper 408 will not always slide in contact with the rotating shaft 111, so the provision of the retaining plates 220 prevents excessive material from falling into this area, ensuring that the material can be completely dried. In addition, the retaining plates 220 also prevent the material from falling onto the first support plate 201 without being dried by the second support plate 202. It is worth noting that the retaining plates 220 can be set to a slope, and the material falling thereon falls to the first support plate 201 or the second support plate 202 through the slope.

[0041] Further, such as Figure 1 As shown, the main housing 100 is provided with a hot air inlet 103 and a moisture removal pipe 104. The hot air inlet 103 is located near the bottom end of the main housing 100, and the moisture removal pipe 104 is located near the top end of the main housing 100. Specifically, during the process of drying the material with the heat source, water vapor in the material evaporates into the interior of the main housing 100. The hot air introduced by the hot air inlet 103 can carry away this water vapor and discharge it through the moisture removal pipe 104.

[0042] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The above embodiments merely illustrate several embodiments of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.

When the scraper moves to the inner end of the second rail, the slide bar and the adjusting plate slide relative to each other, so that the scraper disengages from the second rail, and the elastic member can drive the sliding limit block to have a tendency to approach the outer end of the second rail, thereby driving the scraper to reset.

8. The drying equipment for producing environmental pollution treatment agents according to claim 7, characterized in that: The adjustment plate is provided with a sliding groove, the sliding rod is in sliding cooperation with the sliding groove, and the sliding rod is guided by the sliding groove to enable the scraper to separate from the first track or the second track.

9. The drying equipment for producing environmental pollution treatment agents according to claim 6, characterized in that: The scrapers rotate synchronously with the rotating shaft. When the scrapers move on the elliptical spiral track, adjacent scrapers move at differential speeds to form continuous extrusion of the material.

10. The drying equipment for producing environmental pollution treatment agents according to claim 1, characterized in that: The main shell is provided with a hot air inlet and a dehumidification pipe. Hot air is introduced into the hot air inlet so that water vapor generated during the drying process of the material is discharged from the dehumidification pipe.
