[0002] The vibration drying device generates an exciting force through a vibration motor, enabling the material to form a fluidized state in the drying container and fully contact with hot air, thereby achieving drying. Specifically, the material enters from the feeding port, and the vibration causes the material to continuously turn in the container, exchange heat with the heat medium in the jacket, the moisture evaporates and is discharged in the form of steam, and the dried material is separated and discharged from the discharging port.

[0003] The existing material to be dried is usually a solid-liquid mixture. During the drying process of the material by the vibration dryer, it is necessary to evaporate the liquid in the material into steam and discharge it from the drying container. To ensure the comfort and safety of the processing environment, the steam discharged outside the drying container is usually condensed and then uniformly recovered for treatment; however, the condensation mechanism in the existing vibration drying device cannot condense all the steam, resulting in a low steam recovery rate.

[0031] Before explaining any embodiments of the present application in detail, it should be understood that the present application is not limited to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0032] In the present application, the terms "comprise", "include", "have" or any other variants thereof are intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising an..." does not exclude the presence of additional identical elements in the process, method, article or device comprising the element.

[0033] In the present application, the term "and / or" describes the association relationship of associated objects and indicates that three relationships can exist. For example, A and / or B can represent three cases: A exists alone, A and B exist simultaneously, and B exists alone. In addition, in the present application, the character " / " generally indicates that the associated objects before and after are in an "and / or" relationship.

[0034] In the present application, the terms "connect", "combine", "couple", "mount" can be direct connection, combination, coupling or mounting, or can be indirect connection, combination, coupling or mounting. Among them, by way of example, direct connection means that two parts or components are connected together without the need to provide an intermediate member, and indirect connection means that two parts or components are respectively connected to at least one intermediate member, and these two parts or components are connected through the intermediate member. In addition, "connect" and "couple" are not limited to physical or mechanical connection or coupling, and can include electrical connection or coupling.

[0035] In the present application, those of ordinary skill in the art will understand that relative terms used in combination with a quantity or condition (such as "about", "approximately", "substantially", etc.) are intended to include the recited value and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances caused by manufacturing, assembly, use, etc. associated with a particular value. Such terms should also be considered to disclose a range defined by the absolute values of two endpoints. The relative term may refer to the addition or subtraction of a certain percentage (such as 1%, 5%, 10% or more) of the indicated value. A numerical value without using a relative term should also be disclosed as a specific value with a tolerance. In addition, when expressing a relative angular position relationship (such as substantially parallel, substantially perpendicular), "substantially" may refer to the addition or subtraction of a certain number of degrees (such as 1 degree, 5 degrees, 10 degrees or more) based on the indicated angle.

[0036] In the present application, those of ordinary skill in the art will understand that the functions performed by components can be performed by one component, multiple components, one part, or multiple parts. Similarly, the functions performed by parts can also be performed by one part, one component, or a combination of multiple parts.

[0037] In the present application, the orientation terms such as "upper", "lower", "left", "right", "front", and "back" are described based on the orientation and positional relationship shown in the drawings, and should not be construed as limiting the embodiments of the present application. In addition, in the context, it should also be understood that when it is mentioned that one element is connected "above" or "below" another element, it can not only be directly connected "above" or "below" another element, but also be indirectly connected "above" or "below" another element through an intermediate element. It should also be understood that the orientation terms such as the upper side, lower side, left side, right side, front side, and back side not only represent the positive orientation, but can also be understood as the side orientation. For example, the lower side can include directly below, lower left, lower right, lower front, and lower back, etc.

[0038] Combined with Figures 1 to 5 As shown, the vibration drying device provided in this embodiment is used to complete the drying of materials, which can improve the condensation effect of steam during the drying process, thereby improving the steam recovery rate.

[0039] In actual production, the materials that can be dried by the vibration drying device include, but are not limited to, powder coatings, lithium battery cathode materials, waste resins, etc. In this embodiment, the material dried by the vibration drying device specifically refers to a radioactive medium.

[0040] Specifically, the vibration drying device includes a vibration drying mechanism 100, a heating element 200, and a condensation mechanism 300. The vibration drying mechanism 100 includes a drying kettle 110 for drying materials, and the drying kettle 110 is communicated with the discharge port 1107 of the upstream equipment; the heating element 200 is communicated with the jacket 111 in the drying kettle 110; the condensation mechanism 300 includes a first condensation component 310, a second condensation component 320, and a liquid storage tank 330. The first condensation component 310 is communicated with both the liquid storage tank 330 and the cylinder body 112 in the drying kettle 110, and the second condensation component 320 is communicated with the liquid storage tank 330.

[0041] In this embodiment, the heating element 200 is set as a heat transfer oil unit. The heat transfer oil unit is connected to the bottom of the jacket 111 through the first heating pipe 210 and to the top of the jacket 111 through the second heating pipe 220. During the drying process, the heat transfer oil of the heat transfer oil unit enters the jacket 111 through the first heating pipe 210 to heat and dry the materials in the cylinder 112. When the jacket 111 is filled with the heat transfer oil, the heat transfer oil in the jacket 111 then flows back to the heat transfer oil unit through the second heating pipe 220. By setting the first heating pipe 210 and the second heating pipe 220, the circulation of the heat transfer oil is realized, thereby further improving the heating and drying effect of the materials in the cylinder 112.

[0042] Since the first condensation assembly 310 is connected to the cylinder 112 and the liquid storage tank 330, and the second condensation assembly 320 is connected to the liquid storage tank 330; at the same time, the heating element 200 is connected to the jacket 111. Therefore, after the material to be dried enters the drying kettle 110, the heat transfer oil unit conveys the heat transfer oil into the jacket 111 to heat and dry the materials in the cylinder 112. During the drying process, the free moisture in the material to be dried turns into steam. As the steam in the cylinder 112 increases, the excess steam enters the first condensation assembly 310 and is condensed; then, the condensed water and some uncondensed steam in the first condensation assembly 310 enter the liquid storage tank 330, and then the second condensation assembly 320 connected to the liquid storage tank 330 performs secondary condensation on the uncondensed steam in the liquid storage tank 330, and the condensed water from the secondary condensation flows back to the liquid storage tank 330 for storage. During the whole process, through the cooperation of the first condensation assembly 310 and the second condensation assembly 320, the condensation effect of the steam is improved, thereby improving the steam recovery rate.

[0043] Preferably, the first condensation assembly 310 includes a heat exchanger 311 and a condensate water tank 312. The heat exchange inlet of the heat exchanger 311 is connected to the cylinder 112, the heat exchange outlet is connected to the liquid collection inlet of the liquid storage tank 330, and the condensate water tank 312 is connected to the heat exchanger 311.

[0044] Combined with Figure 1As shown, in this embodiment, the first condensation assembly 310 further includes a condensation pipe 314, a centrifugal pump 313, and a second waste gas recovery member 315. The second waste gas recovery member 315 is communicated with the condensation water tank 312. The heat exchanger 311 is communicated with the cylinder body 112 through the condensation pipe 314. The centrifugal pump 313 is arranged between the heat exchanger 311 and the condensation water tank 312. After the steam in the cylinder body 112 enters the hot gas through the condensation pipe 314, the centrifugal pump 313 pumps the cooling water in the condensation water tank 312 into the heat exchanger 311 to condense the steam in the heat exchanger 311. When the temperature of the cooling water in the heat exchanger 311 is too high, it flows back into the condensation water tank 312 again, and after being cooled by the condensation water tank 312, it is pumped into the heat exchanger 311 again to ensure the first condensation effect on the steam. During the process that the relatively high-temperature cooling water in the heat exchanger 311 flows back into the condensation water tank 312, some non-condensable gases may be brought into the condensation water tank 312. After the non-condensable gases enter the condensation water tank 312, they are directly discharged to the second waste gas recovery member 315 to avoid affecting the heat exchange effect of the heat exchanger 311 due to the re-entry of this part of non-condensable gases into the heat exchanger 311. The specific structures and working principles of the heat exchanger 311 and the condensation water tank 312 refer to the prior art and will not be elaborated here.

[0045] Preferably, the second condensation assembly 320 includes a cryogenic cooler 321 and a refrigeration unit 322. The cryogenic cooler 321 is communicated with both the liquid storage tank 330 and the refrigeration unit 322. The refrigeration unit 322 provides refrigerant for the cryogenic cooler 321. After part of the uncondensed steam enters the liquid storage tank 330, the refrigerant in the refrigeration unit 322 is discharged into the cryogenic cooler 321 to perform secondary condensation on the uncondensed steam in the cryogenic cooler 321. The condensed water formed by the secondary condensation flows back to the liquid storage tank 330 for storage. The specific structures and working principles of the cryogenic cooler 321 and the refrigeration unit 322 refer to the prior art and will not be elaborated here.

[0046] Preferably, the second condensation assembly 320 further includes a first waste gas recovery member 323. The second waste gas recovery member 315 is communicated with the cryogenic cooler 321. During the process that part of the uncondensed steam enters the liquid storage tank 330, the non-condensable gases in the liquid storage tank 330 may enter the cryogenic cooler 321. After the non-condensable gases enter the cryogenic cooler 321, they are directly discharged to the first waste gas recovery member 323 to avoid affecting the liquid storage effect of the liquid storage tank 330 due to the re-entry of this part of non-condensable gases into the liquid storage tank 330.

[0047] Preferably, the second condensation assembly 320 further includes a vacuum pump 324, which is communicated with the cryogenic cooler 321. The vacuum pump 324 is arranged downstream of the cryogenic cooler 321 and located between the cryogenic cooler 321 and the first waste gas recovery member 323. By arranging the vacuum pump 324, on the one hand, since the first condensation assembly 310 is communicated with the liquid storage tank 330 and the drying kettle 110, and the cryogenic cooler 321 is communicated with the liquid storage tank 330, therefore, by arranging the vacuum pump 324 downstream of the cryogenic cooler 321, the inside of the cylinder body 112 can be evacuated, the air pressure inside the cylinder body 112 can be reduced, and low-temperature drying can be realized to reduce the influence of high temperature on the material, thereby reducing the decomposition rate of the material and prolonging the service life of the dried material; on the other hand, it is convenient to extract the steam in the cylinder body 112 into the heat exchanger 311 and the cryogenic cooler 321 to further improve the steam recovery rate, and at the same time avoid the non-condensable gas in the first waste gas recovery member 323 from flowing back to the heat exchanger 311 or the cryogenic cooler 321, so as to increase the working burden of the heat exchanger 311 and the cryogenic cooler 321.

[0048] Preferably, the condensation mechanism 300 further includes a liquid collection tank 340, which is communicated with the liquid storage tank 330. The liquid storage tank 330 is communicated with the liquid collection tank 340 by means of a second recovery pipe 332 and a third recovery pipe 333, so as to facilitate the timely transfer of the liquid in the liquid storage tank 330 into the liquid collection tank 340, ensure the liquid storage effect of the liquid storage tank 330, and avoid affecting the condensation effects of the first condensation assembly 310 and the second condensation assembly 320 due to excessive liquid in the liquid storage tank 330. In order to ensure the liquid transfer effect in the liquid storage tank 330, a sewage pump can also be arranged on the second condensation pipe 314 or the third condensation pipe 314. In addition, a flushing pipe 334 can be arranged. The two ends of the flushing pipe 334 are respectively communicated with the second condensation pipe 314 and the cylinder body 112, and a circulation pump 350 is arranged between the second condensation pipe 314 and the flushing pipe 334. Thus, after the drying is completed, the circulation pump 350 is started, and the liquid in the liquid storage tank 330 is used to flush the cylinder body 112.

[0049] Preferably, the vibration drying mechanism 100 further includes a filter 120, which is arranged above the cylinder body 112, and the first condensation assembly 310 is communicated with the filter 120 through a condensation pipe 314.

[0050] Above the cylinder body 112, there is an installation opening 1106. The filter 120 includes a filter cylinder 121 and a filter screen 122. The filter cylinder 121 is connected to the cylinder body 112 through the installation opening 1106. The filter screen 122 is arranged inside the filter cylinder 121 and is located in the middle of the filter cylinder 121. The condensing pipe 314 communicates with the upper part of the filter cylinder 121. With such an arrangement, when the vacuum pump 324 operates to extract the steam in the cylinder body 112 to the first condensing assembly 310, the steam enters the condensing pipe 314 after being filtered by the filter screen 122. The filter screen 122 can prevent the materials entrained in the filtered steam from entering the heat exchanger 311 and the cryogenic cooler 321, ensuring the condensing effect of the heat exchanger 311 and the cryogenic cooler 321 while extending the service life of the heat exchanger 311 and the cryogenic cooler 321.

[0051] Since the filter cylinder 121 is arranged outside the cylinder body 112, the temperature inside the filter 120 is lower than the temperature of the cylinder body 112. Therefore, when the steam reaches the filter 120, part of the steam may be condensed inside the filter 120, and the condensed water may converge inside the filter 120 and flow back into the cylinder body 112, thus affecting the drying efficiency of the materials inside the cylinder body 112. To avoid this situation, in this embodiment, the heat transfer oil unit also communicates with the lower part of the filter cylinder 121 through the third heating pipe 230 and communicates with the upper part of the filter cylinder 121 through the fourth heating pipe 240. That is, the heat transfer oil unit can also heat the filter element 1102 to prevent the steam from being condensed inside the filter 120.

[0052] Preferably, a liquid outlet pipe 1101 communicating with the cylinder body 112 is arranged at the bottom of the drying kettle 110, and a filter element 1102 corresponding to the liquid outlet pipe 1101 is arranged inside the cylinder body 112. A feeding port 1103 is arranged at the top of the drying kettle 110. The feeding port 1103 communicates with the discharging port 1107 of the upstream equipment. A discharging port 110 is arranged at the bottom of the drying kettle 110, and a storage bucket 140 is arranged corresponding to the drying kettle 110. The storage bucket 140 communicates with the discharging port 1107. After the material to be dried enters the drying kettle 110 from the feeding port 1103, the filter element 1102 can filter the free moisture in the material to be dried and discharge the filtered moisture out of the drying kettle 110 through the liquid outlet pipe 1101. Then, the heat medium is introduced into the drying kettle 110 through the heating port to dry the filtered material. During the whole process, since the free moisture in the material to be dried is filtered out and discharged out of the drying kettle 110, the moisture content of the filtered material in the drying kettle 110 can be reduced, thereby further improving the drying efficiency. After drying, the dried material is discharged into the storage bucket 140 through the discharging port 1107 for storage.

[0053] In addition, during the process of the vibration assembly 130 driving the drying kettle 110 to vibrate, in order to prevent the filter element 1102 from shifting or detaching, in this embodiment, the filter element 1102 is fixedly arranged in the drying kettle 110. The fixed arrangement method can be adaptively adopted according to actual requirements, such as welding, bonding, inlaying, etc., and no specific limitation is made here.

[0054] Preferably, a filter tank 1104 is arranged at the bottom of the drying kettle 110, the liquid outlet pipe 1101 is arranged at the bottom of the filter tank 1104, and the filter element 1102 is arranged at the opening end of the filter tank 1104.

[0055] Combined Figure 1 As shown, with such a setting, on the one hand, after the filter element 1102 filters out the free moisture in the material to be dried, when there is a large amount of filtered moisture, it can be temporarily stored in the filter tank 1104 and then discharged through the drain pipe, avoiding the filtered moisture from contacting the material to be dried again, thereby improving the filtering effect and drying efficiency; on the other hand, there is a certain gap between the filter element 1102 and the liquid outlet pipe 1101, preventing the material in the drying kettle 110 from blocking the liquid outlet pipe 1101 and affecting the liquid discharge speed of the liquid outlet pipe 1101.

[0056] In some other embodiments, in order to further improve the filtering effect and at the same time avoid the residue of the material to be dried blocking the liquid outlet pipe 1101 during the filtering process, a plurality of filter elements 1102 are provided. Along the depth direction of the filter tank 1104, the plurality of filter elements 1102 are sequentially arranged in the filter tank 1104, and in the direction from the opening of the filter tank 1104 to the bottom wall of the filter tank 1104, the filtering precision of the plurality of filter elements 1102 increases in sequence.

[0057] Preferably, the bottom wall of the filter tank 1104 is set as an inclined surface, and the liquid outlet pipe 1101 is arranged at the lowest position of the bottom wall of the filter tank 1104. With such a setting, the moisture temporarily stored in the filter tank 1104 can be discharged through the liquid outlet pipe 1101 as soon as possible, avoiding the moisture from flowing directly on the bottom wall of the filter tank 1104 to further improve the drying effect and drying efficiency.

[0058] The specific form of the filter element 1102 can be adaptively set as a wedge-shaped filter screen, a plain filter screen, a twill filter screen, a sintered filter screen, a folded filter screen, etc. according to the actual situation of the material to be dried. In this embodiment, the filter element 1102 is set as a wedge-shaped filter screen. Due to the design of the wedge-shaped gap of the wedge-shaped filter screen, a larger opening area can be provided, thereby improving the filtering efficiency. Moreover, the wedge-shaped filter screen is easy to clean, and at the same time, due to its strong pressure resistance, it can withstand high pressure differences and frequent cleaning; in addition, the wedge-shaped filter screen can be adjusted according to different material properties to meet various filtering requirements.

[0059] In this embodiment, the opening ratio of the wedge-shaped filter screen is set to 11%, the distance between two adjacent wire bars above is set to 0.2 mm, and the distance between two adjacent rib bars below is set to 18.5 mm. In other embodiments, the dimensional specifications are not limited thereto.

[0060] Furthermore, since the filter element 1102 is set as a wedge-shaped filter screen, in this embodiment, the vibrating dryer further includes a drain pipe and a backwash pipe 334. The drain pipe and the backwash pipe 334 are alternatively connected to the liquid outlet pipe 1101, and the backwash pipe 334 is connected to an external backwash device. During the filtering process, the drain pipe is connected to the liquid outlet pipe 1101 to immediately discharge the moisture filtered by the wedge-shaped filter screen from the drying kettle 110, so as to ensure the drying effect and efficiency; when the pressure difference inside and outside the wedge-shaped filter screen reaches the set value, the backwash is connected to the liquid outlet pipe 1101. At this time, the external backwash device starts to discharge the cleaning fluid to the wedge-shaped filter screen, and the cleaning fluid is used to flush the wedge-shaped filter screen in the reverse direction, so that the wedge-shaped filter screen can restore its filtering performance, thereby ensuring the subsequent use effect of the wedge-shaped filter screen. The backwash device is set with reference to the prior art and will not be elaborated here.

[0061] To further improve the operation convenience, the vibrating dryer further includes a three-way valve. The three-way valve is arranged on the liquid outlet pipe 1101, and both the drain pipe and the backwash pipe 334 are connected to the three-way valve. During the filtering process or the backwash process, the drain pipe or the backwash pipe 334 can be selectively connected to the liquid outlet pipe 1101 through the three-way valve, so as to avoid manually connecting the drain pipe or the backwash pipe 334 to the liquid outlet pipe 1101, thereby improving the use convenience of the vibrating dryer. The specific structure and working principle of the three-way valve are prior art and will not be elaborated here.

[0062] Preferably, the drying kettle 110 includes a cylinder body 112, a jacket 111 and a heat preservation layer 113. The heat preservation layer 113 is coated on the outer side of the cylinder body 112. The jacket 111 is arranged between the heat preservation layer 113 and the cylinder body 112, and a heating port is arranged on the jacket 111. The liquid outlet pipe 1101 and the feeding port 1103 are both arranged on the cylinder body 112. When drying, the heat-conducting oil in the heat-conducting oil unit enters the jacket 111 through the first heating pipe 210 by means of the heating port to heat and dry the materials in the cylinder body 112. The inner side of the heat preservation layer 113 is filled with a heat preservation structure to insulate the whole drying kettle 110, thereby improving the drying effect of the materials in the drying kettle 110.

[0063] Furthermore, a flushing port 1105 is provided at the top of the cylinder body 112. The flushing pipe 334 extends out of the heat preservation layer 113 and is communicated with the liquid storage tank 330 through the flushing pipe 334. A circulation pump 350 is provided on the flushing pipe 334. With such a setting, after the drying is completed, the circulation pump 350 is started, and the liquid formed by steam recovery is sprayed into the cylinder body 112 through the flushing port 1105 to clean the inside of the cylinder body 112. The sewage after cleaning is discharged out of the cylinder body 112 through the liquid outlet pipe 1101 to ensure the next use effect of the drying kettle 110. And after the sewage outlet pipe 1101 discharges the sewage out of the cylinder body 112, it is discharged into the second recovery pipe 332 through the first recovery pipe 331, and then discharged into the liquid collection box 340 through the third recovery pipe 333, so as to complete the recovery of the sewage. In some other embodiments, the flushing port 1105 can also be directly communicated with an external flushing device. After the drying is completed, the external flushing device is started, and the liquid is sprayed into the cylinder body 112 through the flushing port 1105 to clean the inside of the cylinder body 112.

[0064] Preferably, the vibration drying mechanism 100 further includes a vibration assembly 130. The vibration assembly 130 is arranged outside the drying kettle 110 and is in transmission connection with the drying kettle 110 to drive the drying kettle 110 to vibrate. By setting the vibration assembly 130, while the drying kettle 110 vibrates, the heat medium enters the drying kettle 110 from the heating port, heats the filtered materials in the drying kettle 110, increases the heating area of the filtered materials, and ensures that the filtered materials in the drying kettle 110 are heated evenly everywhere, so as to accelerate the evaporation of the moisture of the filtered materials and further improve the drying efficiency.

[0065] Specifically combined with Figure 2 、 Figure 3 and Figure 5 As shown, in this embodiment, the driving member 131 is set as a driving motor. A coupling 134 is provided on the output shaft of the driving motor. The coupling 134 is in transmission connection with the connecting shaft. At the same time, the connecting shaft is in transmission connection with the bearing seat 133 through a connecting bearing. The eccentric wheel 132 is arranged on the connecting shaft. The bearing seat 133 is connected with a connecting seat (not shown in the figure) on the drying kettle 110 through a vibration spring (not shown in the figure). When the vibration dryer works, the coupling 134 rotates together with the output shaft of the driving motor, so as to drive the connecting shaft to rotate, so that the eccentric wheel 132 arranged on the connecting shaft rotates, so that the bearing seat 133 generates vibration, and then drives the drying kettle 110 to vibrate.

[0066] With such a setting, the flow of the materials inside the cylinder body 112 can be achieved through the external vibration assembly 130 to ensure the drying effect. Therefore, it is possible to avoid setting a stirring device inside the cylinder body 112 to reduce the damage to the materials; at the same time, after drying, the residue of the materials inside the cylinder body 112 can be reduced to improve the cleaning convenience; in addition, compared with the vibration drying equipment with an internal stirring device, in this embodiment, the vibration assembly 130 is external, which can reduce the sealing surface of the drying kettle 110, and at the same time, there is no need to perform a sealing treatment between the vibration assembly 130 and the drying kettle 110, so that the overall sealing of the drying kettle 110 is a static seal, ensuring the sealing performance while delaying the wear speed of the sealing structure.

[0067] When the drying kettle 110 is connected to the bearing seat 133, the drying kettle 110 can be set to be vertical or horizontal according to the actual production requirements, and this embodiment does not make specific limitations.

[0068] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
