DETAILED DESCRIPTION

[0025] like Figures 1 to 3As shown, a bearing waterproof structure of a vertical dehydrator includes a housing 10, a filter cartridge 20, a bearing end cover 30, a bearing seat 40 and a first water retaining cylinder 50 with two ends extending therethrough; a drain port 110 is provided at the bottom of the housing 10, and a first shaft through hole 70 is provided for the shaft 170 to pass through; the first water retaining cylinder 50 is airtightly penetrated in the first shaft through hole 70 and extends into the housing 10, and it can be understood that the top of the first water retaining cylinder 50 is higher than the bottom of the housing 10; the bearing end cover 30 airtightly covers the bottom end port of the first water retaining cylinder 50, and a second shaft through hole 70 is provided which is directly opposite to the first shaft through hole 70. Hole 80, the second rotating shaft through hole 80 is for the rotating shaft 170 to pass through; the hole wall of the second rotating shaft through hole 80 extends upward to form a second water retaining tube 60 protruding from the bearing end cover 30 and extending into the first water retaining tube 50. It can be understood that the top end of the second water retaining tube 60 is higher than the top surface of the bearing end cover 30, and the second water retaining tube 60 is connected from top to bottom; the second water retaining tube 60 is spaced apart from the first water retaining tube 50, and the top end of the second water retaining tube 60 is lower than the top end of the first water retaining tube 50; the bearing seat 40 is installed below the bearing end cover 30 and covers the second rotating shaft through hole 80; the bearing seat 40 is used to accommodate the bearing 160.

[0026] On the basis of the above structure, when in use, the bearing 160 is arranged in the bearing seat 40, the rotating shaft 170 sequentially passes through the first rotating shaft through hole 70 and the second rotating shaft through hole 80 to extend into the bearing seat 40 and is received by the bearing 160, the guide assembly 180 is installed in the casing 10 and is in driving connection with the rotating shaft 170, and when dehydration occurs, most of the water falls to the part of the shell bottom of the casing 10 located outside the first water retaining tube 50, and is discharged from the drain outlet 110; and when the water is not discharged in time at the drain outlet 110 and causes water accumulation, the water needs to be accumulated to a height higher than the first water retaining tube 50 before it can overflow into the first water retaining tube 50, thereby playing the role of a first layer of waterproofing; at this time, since the first water retaining tube 50 and the second water retaining tube are arranged at intervals, the overflowing water enters between the first water retaining tube 50 and the second water retaining tube 60, and then the water needs to be higher than the height of the second water retaining tube 60 before it can overflow into the second water retaining tube 60, thereby playing the role of a second layer of waterproofing, so as to reduce the possibility of corrosion and rusting of the bearing 160 and extend the service life of the bearing 160.

[0027] Furthermore, the bearing waterproof structure of the vertical dehydrator also includes an installation cylinder 90, which is arranged at intervals in the casing 10 and covered outside the first water retaining cylinder 50; the top of the installation cylinder 90 is higher than the top of the first water retaining cylinder 50; the installation cylinder 90 is used to install the external guide assembly 180. At this time, the setting of the installation cylinder 90 prevents water splashing from falling directly into the first water retaining cylinder 50 or the second water retaining cylinder 60 during the process of drying the material under the action of centrifugal force, thereby further preventing water.

[0028] Preferably, the bearing waterproof structure of the vertical dehydrator also includes a water baffle 100; the water baffle 100 is located below the top surface of the first water baffle cylinder 50, completely covering the top port of the second water baffle cylinder 60 to prevent water overflowing into the first water baffle cylinder 50 from falling directly into the second water baffle cylinder 60; the bottom surface of the water baffle 100 is spaced from the top surface of the second water baffle cylinder 60, and the side surface of the water baffle 100 is spaced from the inner wall of the first water baffle cylinder 50.

[0029] The present invention also discloses a vertical dehydrator, comprising a bearing 160, a rotating shaft 170, a filter cartridge 20, a guide assembly 180 and the bearing waterproof structure of the vertical dehydrator; the filter cartridge 20 is arranged between the housing 10 and the mounting cylinder 90, and a feed port is provided at the bottom end of the filter cartridge 20, through which a feed pipe can be connected, and the feed pipe extends out of the housing 10 to realize feeding; a side discharge port is provided at the top end of the filter cartridge 20; the bearing 160 is arranged in the bearing seat 40; the rotating shaft 170 is provided It is placed in the mounting cylinder 90 and fixedly connected to the mounting cylinder 90, and the lower end of the rotating shaft 170 passes through the first rotating shaft through hole 70 and the second rotating shaft through hole 80 in sequence and extends into the bearing seat 40, and is supported by the bearing 160; the guide component 180 is installed on the mounting cylinder 90 and is located in the filter cylinder 20; the guide component 180 is used to move with the mounting cylinder 90 when the mounting cylinder 90 rotates with the rotating shaft 170 to guide the material at the feed port to the side discharge port; the drain outlet 110 is arranged outside the filter cylinder 20.

[0030] When in use, the material enters from the feed port, the rotation of the rotating shaft 170 drives the mounting cylinder 90 to rotate, and the guide assembly 180 guides the material to rise. At this time, under the action of centrifugal force, the material throws out the water, and the water is discharged from the filter cylinder 20 outside the filter cylinder 20 and then discharged from the drain port 110, thereby achieving material dehydration.

[0031] like Figure 2 , Figure 4 and Figure 5 As shown, specifically, the guide assembly 180 includes at least two groups of guide units 181; at least two groups of guide units 181 are arranged in sequence and spaced apart around the circumference of the mounting cylinder 90; the guide unit 181 includes at least two guide plates 1811 arranged in sequence and spaced apart along the axial direction of the mounting cylinder 90, and the guide plates 1811 are arranged to be inclined upward, so that when the material contacts the guide plates 1811, friction is generated between the material guide plates 1811 and the material is transported from low to high under the action of the friction force.

[0032] More specifically, the following embodiments may be used between at least two guide sheets 1811 of any two adjacent guide units 181:

[0033] like Figure 4As shown, in the first embodiment, at least two guide pieces 1811 of any two adjacent guide units 181 are arranged one-to-one in the axial direction of the mounting cylinder 90. It can be understood that, in the two adjacent guide units 181, in the axial direction of the mounting cylinder 90, the multiple guide pieces 1811 of one guide unit 181 and the multiple guide pieces 1811 of the other guide unit 181 are arranged one-to-one in the axial direction of the mounting cylinder 90, and the bottom ends and top ends of the correspondingly arranged guide pieces 1811 are respectively flush; at this time, the material is guided by the guide pieces 1811. During the upward movement, when the material jumps over the guide plate 1811 of one group of guide units 181 to the guide plate 1811 of another group of guide units 181, the axial distance it moves is equal to the distance H1 between the two adjacent guide plates 1811 in the axial direction. At this time, the distance H1 between the two adjacent guide plates 1811 needs to be able to allow the material to enter. In this way, the distance the material jumps over is larger, and the energy required is higher, so that the dehydration time is longer and the dehydration is more complete. It is suitable for materials that require a longer dehydration time, but it is easy to accumulate material.

[0034] like Figure 5 As shown, implementation mode 2: at least two guide plates 1811 of any two adjacent guide units 181 are alternately arranged in sequence along the axial direction of the mounting cylinder 90. At this time, when the material moves upward under the guidance of the guide plates 1811, when it moves from the guide plates 1811 of one group of guide units 181 to the guide plates 1811 of another guide unit 181, the axial distance H2 of its movement is smaller than the axial distance H3 between two adjacent blades, which makes it easier to jump layers and avoid material accumulation. The conveying time is short, and it is suitable for materials that are easy to dehydrate and do not require a long dehydration time.

[0035] It should be noted here that the time required for the above-mentioned "materials requiring a longer dehydration time" and "materials not requiring a longer dehydration time" is relative. In actual use, a choice can be made between the two implementation modes according to specific materials and needs.

[0036] Furthermore, the vertical dehydrator also includes a discharge hopper 130 and a discharge pipe 150; both ends of the discharge pipe 150 are respectively connected to the discharge hopper 130 and the side discharge port; the channel of the discharge pipe 150 is inclined downward from one side close to the side discharge port to the other side to facilitate the falling of materials; the side discharge port is provided with a lower discharge port, and it can be understood that the lower discharge port refers to the downward direction; a collection device can be set at the position of the lower discharge port to facilitate material collection.

[0037] Specifically, the vertical dehydrator also includes a feeding mechanism 140 for conveying materials to the feed port. The conveying mechanism can be a spiral feeding mechanism 140, and specifically, a feeding device as described in Patent No. CN207635796U-A Dehydrator can also be used.

[0038] Furthermore, the mounting tube 90 is fixedly connected to the rotating shaft 170 via a connecting plate 120. To ensure the stability of the connection, there are multiple connecting rods, and the multiple connecting plates 120 are arranged in sequence along the axial direction of the mounting tube 90. Here, due to the setting of the connecting plate 120, the height of the first water retaining tube 50 is limited to below the lowest connecting plate 120. In this way, the height of the first water retaining tube 50 is limited. Therefore, there is a possibility that accumulated water overflows into the first water retaining tube 50. At this time, the second water retaining tube 60 can serve as a second layer of waterproofing to improve the waterproof performance.

[0039] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
