Description

Technical Field

[0001] The utility model relates to the field of feeding equipment for dryers, and particularly relates to a drum feeding and distributing device. Background Art

[0002] A drum dryer (also known as a rotary drum dryer, a rotating dryer, etc.) is a contact-type internal heating and conduction-type drying machine. Compared with other drying machines, the drum dryer has a large processing capacity, low fuel consumption, low drying cost, strong anti-overload ability, stable operation of the cylinder body, and high reliability. Therefore, it is widely used in chemical industry, brewing, manufacturing, pharmaceutical, fertilizer, municipal sludge treatment and other aspects.

[0003] The principle of drum drying is that the liquid material to be dried is flowed from a high-level tank into the receiving tank of the drum dryer, so that the liquid material adheres to the surface of the drum. A heat supply medium is passed through the drum, and the liquid material is dried by heat transfer from the drum wall during the rotation of the drum. The drum completes processes such as film forming, vaporization, and dehydration in one rotation cycle. The dried material is scraped off by a scraper and conveyed to a finished product storage tank through a screw.

[0004] However, in actual use, the drum dryers on the current market cannot make the liquid material adhere evenly to the surface of the drum, resulting in difficulty in controlling the thickness of the liquid material adhering to the surface of the drum, causing uneven heating of the liquid material during the drying process, and affecting the drying efficiency and the shape of the final product. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the problem that the drum dryers on the current market cannot make the liquid material adhere evenly to the surface of the drum in actual use, resulting in difficulty in controlling the thickness of the liquid material adhering to the surface of the drum, causing uneven heating of the liquid material during the drying process, and affecting the drying efficiency and the shape of the final product. The utility model provides a drum feeding and distributing device, which can make the liquid material adhere evenly to the surface of the drum.

[0006] To solve the above technical problems, an embodiment of the utility model discloses a drum feeding and distributing device, including:

[0007] A drum, having an outer shell and an inner shell, and a cavity is formed between the outer wall of the inner shell and the inner wall of the outer shell;

[0008] A flexible scraping strip, at least a part of which is located in the cavity, and the flexible scraping strip is disposed opposite to the outer wall of the inner shell, and the flexible scraping strip can abut against the outer wall of the inner shell;

[0009] A feed pipe, having a discharge end, the discharge end is located in the cavity, and the discharge end is disposed towards the flexible scraping strip, and the feed pipe can supply the liquid material to the flexible scraping strip.

[0010] With the above technical solution, the flexible scraping strip is made of soft material and can effectively adhere to the outer wall of the inner shell. After the liquid material reaches the flexible scraping strip through the feed pipe, since the flexible scraping strip can abut against the outer wall of the inner shell, the liquid material can be evenly attached to the outer wall of the inner shell of the drum through the flexible scraping strip, so that the liquid material can be evenly heated during the drying process, improving the drying efficiency and the quality of the product.

[0011] According to a specific embodiment of the present invention, the outer shell is provided with a first through opening;

[0012] The flexible scraping strip can enter or move away from the cavity through the first through opening.

[0013] With the above technical solution, by moving the flexible scraping strip away from the cavity through the first through opening, the flexible scraping strip can be disassembled relative to the drum, which is convenient for the maintenance or cleaning of the flexible scraping strip to extend its service life and improve economy, or directly replace the flexible scraping strip to ensure that the liquid material is evenly attached to the outer wall of the inner shell through the flexible scraping strip, thereby improving the drying efficiency and drying quality of the liquid material.

[0014] According to a specific embodiment of the present invention, it further includes:

[0015] An adjusting assembly, fixedly connected to the flexible scraping strip, and the adjusting assembly can drive the flexible scraping strip to approach or move away from the outer wall of the inner shell.

[0016] With the above technical solution, by providing the adjusting assembly and enabling the adjusting assembly to drive the flexible scraping strip to approach or move away from the outer wall of the inner shell, the distance between the flexible scraping strip and the outer wall of the inner shell can be adjusted, so as to adjust the thickness of the liquid material attached to the outer wall of the inner shell to meet the requirements of different processes.

[0017] According to a specific embodiment of the present invention, the adjusting assembly includes:

[0018] A connecting rod, having a first end and a second end;

[0019] A hinge, rotatably connected to the first end;

[0020] A connecting plate, rotatably connected to the second end;

[0021] A scraping plate, fixedly connected to the connecting plate, and one end of the flexible scraping strip is fixed to the scraping plate.

[0022] With the above technical solution, the connecting rod can rotate relative to the hinge, and the connecting plate can rotate relative to the connecting rod, so that the adjusting assembly has a high degree of freedom, and thus when the scraping plate drives the flexible scraping strip to move, it is more flexible and can accurately adjust the distance between the flexible scraping strip and the outer wall of the inner shell.

[0023] According to a specific embodiment of the present utility model, a nozzle is provided at the discharge end of the feed pipe, and the nozzle is arranged facing the flexible scraping strip.

[0024] By adopting the above technical solution, the liquid material can be evenly sprayed onto the flexible scraping strip through the nozzle, which can further improve the evenness of the attachment of the liquid material to the outer wall of the inner shell.

[0034] To make the purpose, technical solution and advantages of the present utility model clearer, the embodiments of the present utility model will be further described in detail below in conjunction with the drawings.

[0035] Refer to Figure 1 , the embodiment of the present application provides a drum feeding and distributing device, including: a drum 1, a flexible scraping strip 2, a feed pipe 3 and a rotating shaft 4.

[0036] Specifically, the drum 1 has an outer shell 11 and an inner shell 12. The outer wall 121 of the inner shell 12 and the inner wall 111 of the outer shell 11 enclose a cavity 13. At least a part of the flexible scraping strip 2 is located in the cavity 13, and the flexible scraping strip 2 is disposed opposite to the outer wall 121 of the inner shell 12, and the flexible scraping strip 2 can abut against the outer wall 121 of the inner shell 12. The feed pipe 3 has a discharge end 31, and the discharge end 31 is located in the cavity 13 and is disposed facing the flexible scraping strip 2. Through the feed pipe 3, a liquid material can be provided to the flexible scraping strip 2.

[0037] Exemplarily, when the drum feeding and distributing device works, the inner shell 12 rotates counterclockwise along the rotating shaft 4 in the direction R1 to make the liquid material adhere to the outer wall 121 of the inner shell 12. The application embodiment does not specifically limit the rotation direction of the inner shell 12. For example, in some other possible embodiments, the inner shell 12 rotates clockwise along the rotating shaft 4 in the direction R2.

[0038] Among them, the flexible scraping strip 2 is made of a flexible material and is relatively soft, so that it can effectively adhere to the outer wall 121 of the inner shell 12. After the liquid material reaches the flexible scraping strip 2 through the feed pipe 3, since the flexible scraping strip 2 can adhere to the outer wall 121 of the inner shell 12, the liquid material can be evenly attached to the outer wall 121 of the inner shell 12 of the drum 1 through the flexible scraping strip 2, so that the liquid material can be evenly heated during the drying process, improving the drying efficiency and the quality of the product.

[0039] In some possible implementation manners, with continued reference to Figure 1 , the outer shell 11 is provided with a first through port 112, and the flexible scraping strip 2 can enter or leave the cavity 13 through the first through port 112. In other words, the flexible scraping strip 2 in the embodiment of the present application is detachable relative to the drum 1.

[0040] Exemplarily, by moving the flexible scraping strip 2 away from the cavity 13 through the first through port 112, the flexible scraping strip 2 can be detached from the drum 1, so as to facilitate the maintenance or cleaning of the flexible scraping strip 2 to extend the service life of the flexible scraping strip 2 and improve the economy, or directly replace the flexible scraping strip 2 to ensure that the liquid material is evenly attached to the outer wall 121 of the inner shell 12 through the flexible scraping strip 2, thereby improving the drying efficiency and drying quality of the liquid material.

[0041] In some possible implementation manners, with continued reference to Figure 1 , the drum feed distribution device in the embodiment of the present application further includes an adjustment assembly 21. The adjustment assembly 21 is fixedly connected to the flexible scraping strip 2, and the adjustment assembly 21 can drive the flexible scraping strip 2 to approach or move away from the outer wall 121 of the inner shell 12, so as to adjust the distance between the flexible scraping strip 2 and the outer wall 121 of the inner shell 12, thereby adjusting the thickness of the liquid material attached to the outer wall 121 of the inner shell 12 to meet the requirements of different processes.

[0042] Exemplarily, by driving the flexible scraping strip 2 to approach the outer wall 121 through the adjustment assembly 21, the thickness of the liquid material attached to the outer wall 121 of the inner shell 12 can be made thinner; by driving the flexible scraping strip 2 to move away from the outer wall 121 through the adjustment assembly 21, the thickness of the liquid material attached to the outer wall 121 of the inner shell 12 can be made thicker.

[0043] Regarding the specific manner of adjusting the distance between the flexible scraping strip 2 and the outer wall 121 of the inner shell 12, the embodiment of the present application does not make any restrictions. Exemplarily, in some other possible implementation manners, with continued reference to Figure 1 , the adjustment assembly 21 can make one end of the flexible scraping strip 2 close to the inner shell 12 tilt upward or downward relative to the inner shell 12 in the vertical direction Z, so as to adjust the distance between the flexible scraping strip 2 and the outer wall 121 of the inner shell 12.

[0044] With continued reference to Figure 1, specifically, the adjusting assembly 21 includes: a hinge 211, a connecting rod 212, a connecting plate 213, and a scraping plate 214. Among them, the connecting rod 212 has a first end 2121 and a second end 2122. The hinge 211 is rotatably connected to the first end 2121, the connecting plate 213 is rotatably connected to the second end 2122, the scraping plate 214 is fixedly connected to the connecting plate 213, and one end of the flexible scraping strip 2 is fixed to the scraping plate 214.

[0045] Among them, the hinge 211 is fixed (for example, the hinge 211 is fixed to the ground or the hinge 211 is fixed to other supporting components). The connecting rod 212 can rotate relative to the hinge 211, and the connecting plate 213 can rotate relative to the connecting rod 212, so that the adjusting assembly 21 has a high degree of freedom. Thus, when the scraping plate 214 drives the flexible scraping strip 2 to move, it is more flexible and can accurately adjust the distance between the flexible scraping strip 2 and the outer wall 121 of the inner shell 12.

[0046] Exemplarily, the cross-sectional shape of the scraping plate 214 is "C"-shaped, and the end of the flexible scraping strip 2 away from the inner shell 12 is fixed to the inner side of the "C" shape of the scraping plate 214. For the fixing manner between the scraping plate 214 and the flexible scraping strip 2, the embodiments of the present application do not make specific limitations, as long as the scraping plate 214 can drive the flexible scraping strip 2 to move relative to the outer wall 121 of the inner shell 12. Exemplarily, the flexible scraping strip 2 is fixedly connected to the scraping plate 214 by bolts.

[0047] In some possible implementation manners, a nozzle 32 is provided at the discharge end of the feed pipe 3. The nozzle 32 is arranged facing the flexible scraping strip 2, and the nozzle 32 is used to uniformly spray the liquid material onto the flexible scraping strip 2, which can further improve the evenness of the attachment of the liquid material on the outer wall 121 of the inner shell 12.

[0048] Exemplarily, the outer shell 11 is provided with a second through port 113. The second through port 113 is communicated with the cavity 13. A part of the feed pipe 3 is located in the second through port 113, that is, the feed roller 3 can extend into the cavity through the second through port 113 to spray the liquid material onto the flexible scraping strip 2.

[0049] In some possible implementation manners, the feed distribution device of the present application further includes a roller bracket 14. The roller bracket 14 is connected to the outer shell 11 to support the roller 1 on the ground.

[0050] Although the present invention has been illustrated and described by referring to some preferred embodiments of the present invention, those of ordinary skill in the art should understand that the above content is a further detailed description of the present invention in combination with specific implementation manners, and it cannot be determined that the specific implementation of the present invention is only limited to these descriptions. Those skilled in the art can make various changes in form and details, including making several simple deductions or substitutions, without departing from the spirit and scope of the present invention.
