DETAILED DESCRIPTION

[0023] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0024] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and cannot be understood as limiting the specific scope of protection of the present application.

[0025] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0026] One of the preferred embodiments of the present application is as follows: Figures 1 to 5 As shown, a horizontal drying device includes a drying kettle 1 and a stirring structure installed in the drying kettle 1, and the stirring structure is mainly composed of a rotating shaft 2 and a stirring blade 3 installed on the rotating shaft 2. Figure 1As shown, the rotating shaft 2 is rotatably installed in the drying kettle 1 and forms a connection 9 with the inner side of the drying kettle 1, so people will seal this connection 9, for example, by setting a sealing ring; because the drying kettle 1 is horizontal, when the material is high, it will "flood" this connection 9, and then it will still make it very easy for the material with smaller particle size to enter the connection 9. Therefore, a blowing mechanism 7 can be installed on the outside of the drying kettle 1, and the blowing mechanism 7 and the rotating shaft 2 are matched.

[0027] It is understandable that, when drying, the blowing mechanism 7 can eject airflow from the outside of the rotating shaft 2, and the ejection position corresponds to the connection 9. We know that the stirring structure will also operate at this time, that is, the rotating shaft 2 will also rotate, so the ejected airflow will also make a circular motion, and then the rotating ejected airflow will form an air curtain, so that the air curtain can isolate the connection 9 from the material, which greatly reduces the probability of materials with smaller particle sizes entering the connection 9, thereby effectively protecting the sealing between the rotating shaft 2 and the drying kettle 1. In addition, the setting of the blowing mechanism 7 is not limited to isolating the connection 9, but can also play an auxiliary stirring role during the drying process, so that the distribution of the material in the drying kettle 1 is more uniform, and the drying efficiency is improved.

[0028] As a further description of the above embodiment: Figure 2 As shown, a flow channel 8 is provided inside the rotating shaft 2, and the blowing mechanism 7 includes an air inlet pipe 701 and a sleeve 702. The sleeve 702 is installed on the outside of the drying kettle 1 and is rotatably sleeved with the rotating shaft 2. For example, the sleeve 702 is rotatably sealed with the rotating shaft 2 through a bearing; and an annular cavity 11 is provided on the inner side of the sleeve 702. The annular cavity 11 and the rotating shaft 2 are matched so as to be disconnected from the outside, and the air inlet pipe 701 is installed outside the sleeve 702 and is connected to the annular cavity 11 inside the sleeve 702. The first end of the flow channel 8 is connected and matched with the annular cavity 11, and the second end of the flow channel 8 is located outside the rotating shaft 2 and corresponds to the connection 9.

[0029] It is understandable that when drying is carried out, compressed gas can be injected into the air inlet pipe 701 through an air pump, and then the gas will enter the annular cavity 11. The gas in the annular cavity 11 will enter from the first end of the flow channel 8, and then be ejected from the second end of the flow channel 8 to the connection 9, and form an air curtain under the rotation of the rotating shaft 2.

[0030] It should be noted that, since the annular cavity 11 is annular in shape and the first end of the flow channel 8 is in communication with the annular cavity 11 , no matter how the rotating shaft 2 rotates, the flow channel 8 and the annular cavity 11 are always in communication.

[0031] In this embodiment, Figure 2As shown, the flow channel 8 includes an air inlet groove 801, an air outlet groove 802 and an inner groove 803, and each groove can be processed in the following manner: first, the inner groove 803 is drilled at the end of the rotating shaft 2 along its axial direction, and then the air inlet groove 801 and the air outlet groove 802 are respectively drilled on the outside of the rotating shaft 2 along its radial position, so that the air inlet groove 801 and the air outlet groove 802 are both connected to the inner groove 803, and finally the end of the rotating shaft 2 is sealed (that is, the end of the inner groove 803 is sealed), so that the entire flow channel 8 can be formed. The inner groove 803 can also be arranged in the following manner: the part of the rotating shaft 2 that cooperates with the blowing mechanism 7 adopts a hollow tube with sufficient strength, and then the two ends of the hollow tube are sealed to form the inner groove 803.

[0032] Specifically, Figure 2 As shown, the first end of the air inlet groove 801 forms the first end of the flow channel 8, the second end of the air inlet groove 801 is connected to the inner groove 803, the first end of the air outlet groove 802 is connected to the inner groove 803, and the second end of the air outlet groove 802 forms the second end of the flow channel 8. It can be understood that the flow direction of the air flow is: from the air inlet pipe 701 to the annular cavity 11, from the annular cavity 11 to the air inlet groove 801, from the air inlet groove 801 to the inner groove 803, from the inner groove 803 to the air outlet groove 802, and finally the air flow is ejected from the air outlet groove 802 to the connection 9.

[0033] Further, such as Figure 2 As shown, if the air inlet groove 801 and the air outlet groove 802 are set to be single, it will have a greater impact on the air intake and air outlet. Therefore, the air inlet groove 801 and the air outlet groove 802 can be set to multiple and equidistantly arranged, which can greatly improve the uniformity of the air flow in and out and the air flow. At the same time, in order to prevent the material in the drying kettle 1 from flowing back into the flow channel 8, a one-way valve 10 can be set at the second end of the air outlet groove 802, thereby protecting the normal operation of the blowing mechanism 7 and extending its service life.

[0034] In one of the embodiments of the present application, Figure 1 As shown, a feeding port 5 is provided on one side (left side) of the bottom end of the drying kettle 1, and a purge port 4 is provided on the other side (right side) of the bottom end of the drying kettle 1. It can be understood that when feeding, the feeding port 5 is opened, and the purge port 4 can be connected to an external air pump, so that the purge port 4 can generate a strong airflow purge force, and then the materials on the right side are blown and accumulated near the feeding port 5 on the left side, so as to achieve fast and smooth feeding and prevent the materials in the drying kettle 1 from being discharged incompletely. Of course, in order to ensure the purge effect, the purge port 4 can be designed to be adjustable so as to adjust the purge force and angle according to different material characteristics and drying requirements.

[0035] Further, such as Figure 1As shown, a plunger discharge valve 6 can be installed at the discharge port 5 to realize the opening and closing of the discharge port 5. When the plunger discharge valve 6 is closed, the valve core of the plunger discharge valve 6 is flush with the inner bottom end of the drying kettle 1, that is, at this time, the discharge port 5 can be closed and flush with the bottom end of the kettle, so that no dead angle (area) is generated at the discharge port 5, thereby avoiding the accumulation of materials and water here, and further improving the uniformity of drying. Of course, the specific structure of the plunger discharge valve 6 is also common knowledge known to those skilled in the art, so it will not be repeated.

[0036] like Figure 4 As shown, a plurality of equally spaced drain ports 12 may be provided at the bottom of the drying kettle 1, and a filter element 13 may be detachably installed in the drain port 12, so that the moisture contained in the material in the drying kettle 1 may be discharged through the action of the drain port 12 and the filter element 13.

[0037] It is worth mentioning that after the material is drained, the drain port 12 can also play such a role, that is, the drain port 12 can be connected and cooperated with an external air source (such as an air pump). During drying, the air pump transports the airflow from the drain port 12 to the bottom end of the drying kettle 1, which can make the material have a boiling effect. On the one hand, this improves the drying effect between the materials, and on the other hand, it can prevent the materials from adhering and accumulating at the bottom end of the drying kettle 1, thereby further promoting the drying uniformity of the materials.

[0038] As a further description of the above embodiment, Figure 4 and Figure 5 As shown, the filter element 13 can adopt such a structure and installation method: a trough body connected to the drying kettle 1 is provided at the bottom end thereof, a bushing 14 is fixedly installed in the trough body, and the filter element 13 includes a filter cartridge, that is, a cylindrical structure, and the filter cartridge can be inserted into the bushing 14 for installation, which can facilitate the installation and disassembly of the filter element 13 at a later stage.

[0039] Specifically, Figure 5 As shown, the filter cartridge includes a mounting portion 1303, an integrally formed cylinder 1301 and a filter screen 1302. The filter screen 1302 is located at the top of the cylinder 1301, that is, the top of the cylinder 1301 is provided with filter holes arranged at equal distances to form the filter screen 1302; the mounting portion 1303 is provided at the outer bottom of the cylinder 1301. It can be understood that during installation, the cylinder 1301 can be inserted into the bushing 14 until the filter screen 1302 is matched with the inner bottom of the drying kettle 1, and then the mounting portion 1303 and the bushing 14 can be fixedly connected by screws.

[0040] It should be known that the outer shell of the drying kettle 1 has a certain thickness, and the installation of the filter 13 must be provided with a trough body at the bottom of the kettle. If the filter 13 is installed at the bottom of the trough body, materials will be accumulated in the trough body, which may form a drying dead corner or a material feeding dead corner; and if the filter 13 is installed at the top of the trough body and is flush with the inner bottom of the drying kettle 1, the trough body has a certain depth, which will cause certain difficulties in the later installation and removal of the filter 13. The above-mentioned cylindrical structural design can improve its disassembly efficiency while ensuring the installation effect. At the same time, the setting of the cylinder 1301 can also support the relatively weak filter screen 1302 at the top, greatly improving the strength and installation stability of the filter 13.

[0041] Further, such as Figure 1 As shown, since the drying kettle 1 is a horizontal structure, the material will easily accumulate on the top of the filter element 13 (i.e., the filter screen 1302), thereby causing the filter element 13 to be blocked. In order to solve this problem, as shown in FIG. Figure 4 As shown, a plurality of stirring blades 3 cooperating with the filter element 13 can be installed on the outside of the rotating shaft 2; that is, when the stirring structure is stirring the material, the stirring blades 3 can clean the material on the filter element 13 under the driving action of the rotating shaft 2, thereby solving the problem of material accumulation and blockage, that is, the stirring blades 3 at this time not only play a stirring role but also play a role of a "scraper".

[0042] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application. The present application may have various changes and improvements without departing from the spirit and scope of the present application, and these changes and improvements fall within the scope of the present application for which protection is sought.
