Description

Technical Field

[0001] The utility model relates to the technical field of bearing application, in particular to a bearing seat structure used for a distribution belt of a sludge drying line. Background Art

[0002] The patent number CN218633537U is now public, which is a special protective cover for the distribution belt motor of the sludge drying line. The public patent proposes that in the production process of the drying line, the distribution belt is one of the core equipment. Its function is to form the sludge produced by the thin-layer evaporator into noodle-shaped sludge through a shredder, and then evenly distribute it to the belt machine. However, when the shredder forms the noodle-shaped sludge, it needs to use a grid with holes. During the production process, the grid needs to be cleaned frequently, and the grid is very close to the distribution belt. At the same time, the sludge itself contains a lot of water, so the distribution belt is in a humid environment for a long time when in use, and the bearing base on the distribution belt is also in a humid working condition for a long time. Therefore, the existing bearing seat for the distribution belt of the sludge drying line has the following problems:

[0003] 1. The bearing bases on existing distribution belts are mostly made of cast iron, which is very susceptible to corrosion under the influence of humid air, water vapor, and possible corrosive media. This reduces the strength of the base structure and affects the stability and service life of the entire drying line.

[0004] 2. Most of the bearings in existing bearing bases are single-row bearings. Single-row bearings have limited load-bearing capacity under complex and humid working conditions, and are prone to damage and increased wear. This requires frequent repairs and replacements, increasing equipment operation and maintenance costs and downtime, seriously affecting production efficiency.

[0005] 3. The waterproof and anti-corrosion effect of the bearings in the existing bearing base is poor, because the sludge itself contains a large amount of water and corrosive substances (such as various acidic and alkaline components and microbial metabolites, etc.). These components can easily enter the bearing, causing problems such as lubrication failure, component corrosion and increased wear, thereby reducing the service life of the bearing.

[0039] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0040] In the present invention, the term "plurality" refers to two or more than two, unless otherwise expressly defined. The term "and / or" used herein includes any and all combinations of one or more of the relevant listed items. Terms such as "installation", "connection", "connection", and "fixed" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; "connection" can be a direct connection or an indirect connection through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0041] It should be noted that when an element is referred to as being "assembled to," "mounted to," "fixed to," or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0042] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0043] like Figures 1-9 As shown, the utility model provides a bearing seat structure for the distribution belt of the sludge drying line, including a seat body 1 made of stainless steel, a double-row bearing 2 installed in the seat body 1, a sealing plate 3 installed on the front end surface of the seat body 1, an outer convex plate 4 installed on the rear end surface of the seat body 1, and an extrusion assembly 5 for connecting to the shaft body. The seat body 1 can be made of 304 stainless steel or 316 stainless steel. The sealing plate 3 and the outer convex plate 4 are respectively provided with a water absorption assembly 6. A raised contact portion is provided on one end surface of the sealing plate 3. The sealing plate 3 is fixedly mounted with the double-row bearing 2 through the raised contact portion. The extrusion assembly 5 is used to squeeze the water absorption assembly 6.

[0044] The extrusion assembly 5 includes an optical axis fixing ring 51 for connecting to the shaft body, a sleeve 52 connected to the outer wall of the optical axis fixing ring 51, a tension spring 53 provided in the inner cavity of the sleeve 52, and an extrusion rod 54 provided in the inner cavity of the sleeve 52 and movably passing through the optical axis fixing ring 51;

[0045] The water absorption component 6 includes a water absorption groove 61 respectively opened on the sealing plate 3 and the outer convex plate 4, a sponge body 62 arranged in the water absorption groove 61 and a fixed plate 63 installed in the water absorption groove 61. An extrusion port 64 is opened through the fixed plate 63. When the extrusion rod 54 rotates in the circumferential direction, it intermittently corresponds to the extrusion port 64, and the inner bottom wall of the water absorption groove 61 is opened with a drainage hole 65 extending to the bottom wall of the sealing plate 3 or the outer convex plate 4.

[0046] Furthermore, when the seat body 1 is in use, the sealing plate 3 is an indispensable accessory for sealing and fixing the double-row bearing 2. However, when facing the installation of the outer convex plate 4, the staff can install it according to the actual situation. Specifically, when the front end face and the rear end face of the seat body 1 are respectively in a situation where water splashes, the sealing plate 3 and the outer convex plate 4 can be installed, and when the rear end face of the seat body 1 is in a situation where there is no water splashing, only the water absorption component 6 on the sealing plate 3 can be installed. When the front end face and the rear end face of the seat body 1 are both in a situation where there is no water splashing, the staff only needs to install the sealing plate 3, and the water absorption component 6 can be installed selectively, which has strong applicability.

[0047] Combine Figure 5 、 Figure 6 and Figure 8 As shown, as a further feature, the outer wall of the seat body 1 is provided with a stepped positioning hole 7 which is communicated with its inner cavity, and an oil filling joint 8 is provided in the stepped positioning hole 7. A threaded through hole 9 corresponding to the stepped positioning hole 7 is provided on the outer ring of the double-row bearing 2, and one end of the oil filling joint 8 is threadedly connected to the threaded through hole 9, and a dust cap 10 is provided at the other end of the oil filling joint 8, which is used to prevent leakage of lubricating oil and entry of foreign matter.

[0048] Specifically, the threaded through hole 9 is opened on the outer ring wall of the double-row bearing 2, and there can be two or one threaded through hole. When one threaded through hole 9 is opened, the threaded through hole 9 is opened between the two sets of balls in the double-row bearing 2, such as Figure 8 As shown, if two threaded through holes 9 are opened, the opening position of each threaded through hole 9 corresponds to the outer wall of each group of balls (not shown in the figure). In this way, after the oil filling connector 8 is connected through the threaded through hole 9, the lubricating oil is injected into the double-row bearing 2, which can effectively ensure the smoothness of the double-row bearing 2 during high-speed operation, effectively reduce the wear caused by friction, and extend the service life of the bearing. In addition, the injected lubricating oil can also effectively control the operating temperature of the bearing, prevent the bearing from being damaged due to overheating, and also reduce the possibility of rust and corrosion of the bearing to a certain extent.

[0049] In addition, the existing traditional bearings (SKF SYF-506) used in the distribution belt of the sludge drying line are replaced with double-row bearings 2, so that the traditional single-row bearings are abandoned and the double-row bearings 2 structure is selected. Compared with single-row bearings, they can withstand greater radial and axial forces at the same time, and are well adapted to the complex stress conditions such as vibration and eccentric load that may occur in equipment under humid environments. They effectively disperse the load, reduce the pressure between the single rolling element and the raceway of the bearing, reduce the wear rate, extend the service life of the bearing, and improve its working reliability in humid and harsh environments. The double-row bearings 2 use a model that can be purchased on the market, which is SKF 1306-ETN9.

[0050] Combine Figure 4 、 Figure 5 、 Figure 8 and Figure 9 As shown, as a further example, the water absorption groove 61 includes a sponge area 611 and a fixed area 612, the sponge body 62 is arranged in the sponge area 611, the drainage hole 65 is opened on the inner bottom wall of the sponge area 611, and the fixed plate 63 is arranged in the fixed area 612, the inner circle diameter value of the fixed area 612 is smaller than the outer circle diameter value of the sponge area 611, and the water absorption groove 61 is further provided with an arc-shaped thin plate 66 located between the sponge body 62 and the fixed plate 63, the outer circle diameter value of the arc-shaped thin plate 66 is smaller than the inner circle diameter value of the fixed area 612, and the outer circle diameter value of the arc-shaped thin plate 66 is smaller than the inner circle diameter value of the fixed area 612. The plate 66 can move on the inner ring side of the fixed area 612, thereby achieving the effect of the arc-shaped thin plate 66 squeezing the sponge 62. At the same time, the arc-shaped thin plate 66 adopts an arc-shaped design, so that the arc-shaped thin plate 66 will not affect the shaft when it moves under force, thereby ensuring the normal rotation of the shaft. It is worth noting that the arc-shaped thin plate 66 shown in the figure in this article can have a smaller curvature during actual production, and only needs to be slightly larger than the extrusion port 64, thereby avoiding the displacement of the arc-shaped thin plate 66. In addition, during actual production of the arc-shaped thin plate 66, the processing of the anti-deflection groove 11 is adapted to the arc-shaped thin plate 66 to ensure the stability of the arc-shaped thin plate 66.

[0051] It should be noted that the inner ring and outer ring referred to above are that the small circle of an annular ring is the inner ring and the large circle is the outer ring, and the outer ring and inner ring of the arc-shaped thin plate 66 are the same.

[0052] Specifically, such as Figure 9As shown, a limiting protrusion is provided at the inner circle of the sponge area 611, and a limiting rib is provided at the outer circle, so as to facilitate the positioning of the sponge body 62; and through the design of the arc-shaped thin plate 66, when the extrusion rod 54 squeezes water from the sponge body 62 through the extrusion port 64, the arc-shaped thin plate 66 can effectively protect the sponge body 62, and at the same time, when the bottom end of the arc-shaped thin plate 66 is squeezed, the bottom end of the arc-shaped thin plate 66 can be deflected, thereby squeezing the bottom end of the sponge body 62, prompting the squeezed water to be discharged outward through the drainage hole 65, and after the water at the bottom end of the sponge body 62 is discharged, the water in other parts of the sponge body 62 will continue to fill the squeezed part through capillary action, thereby ensuring the continuous water absorption function of the sponge body 62.

[0053] Combine Figure 4 、 Figure 5 and Figure 9 As shown, as a further feature, an anti-skew groove 11 is provided on one side of the fixing plate 63 close to the sponge body 62 , and an arc-shaped thin plate 66 is provided in the anti-skew groove 11 , and the inner diameter of the anti-skew groove 11 is equal to the inner circle diameter of the fixing area 612 .

[0054] Specifically, through the design of the anti-deflection groove 11, when the fixing plate 63 is connected to the sealing plate 3 or the outer convex plate 4, the arc-shaped thin plate 66 can be arranged in the anti-deflection groove 11, thereby ensuring the installation stability of the arc-shaped thin plate 66. At the same time, because the inner diameter value of the anti-deflection groove 11 is equal to the inner ring diameter value of the fixing area 612, after the fixing plate 63 is tightly connected to the sealing plate 3 or the outer convex plate 4, the arc-shaped thin plate 66 can smoothly squeeze the sponge 62 through the fixing area 612.

[0055] Combine Figure 3 and Figure 7 As shown, as a further feature, a stepped guide hole 55 is provided on the optical axis fixing ring 51, the extrusion rod 54 is movably arranged in the stepped guide hole 55, and the inner wall of the end of the stepped guide hole 55 is provided with a threaded section 56, one end of the sleeve 52 is connected to the stepped guide hole 55 through the threaded section 56, and the outer wall of the extrusion rod 54 is fixedly connected to a limiting ring 57, and the limiting ring 57 is provided in the stepped guide hole 55.

[0056] Specifically, through the design of the threaded section 56, the sleeve 52 can be fixedly connected to the optical axis fixing ring 51, so that by means of the tension spring 53 set in the sleeve 52, the tension spring 53 can exert a force on one end of the extrusion rod 54, prompting the extrusion rod 54 to be able to resist on the fixing plate 63. In this way, when the shaft body rotates and drives the optical axis fixing ring 51 to rotate, the extrusion rod 54 can use the force of the tension spring 53 to squeeze the arc-shaped thin plate 66 through the extrusion port 64, prompting the arc-shaped thin plate 66 to squeeze the moisture in the sponge 62, thereby ensuring the continuous water absorption function of the sponge 62.

[0057] Furthermore, with the help of the design of the limiting ring 57, the movement distance of the extrusion rod 54 is limited when it is subjected to the force of the tension spring 53, which is beneficial for the extrusion rod 54 to squeeze the arc-shaped thin plate 66 while facilitating its separation from the extrusion port 64, thereby ensuring the normal rotation of the shaft body. It is worth noting that a contact section is provided at one end of the extrusion rod 54, and the contact section is made of rubber, and one end of the rubber contact section is hemispherical, and a guide groove is provided on the corresponding fixed plate 63, and the extrusion port 64 is provided in the guide groove, and the outer edge of the extrusion port 64 and the guide groove are chamfered, thereby facilitating one end of the extrusion rod 54 to separate from the extrusion port 64, and the design of the contact section made of rubber can avoid the problem of rigid contact between the extrusion rod 54 and the edge of the extrusion port 64 when the extrusion rod 54 separates from the extrusion port 64, thereby effectively ensuring the service life of the fixed plate 63 and reducing structural damage.

[0058] Furthermore, a ball is embedded in one end of the extrusion rod 54, and in actual use, a rolling ball can be installed at the top of the contact section at one end of the extrusion rod 54, so as to avoid the problem of the rubber material contacting the fixed plate 63 to increase the friction and affect the rotation of the shaft.

[0059] Combine Figure 1 、 Figure 2 、 Figure 4 and Figure 5 As shown, as a further feature, a plurality of mounting holes 12 are respectively provided on the front and rear end surfaces of the base body 1, and positioning members are respectively provided in the plurality of mounting holes 12. The blocking plate 3 and the outer convex plate 4 are respectively fixedly mounted to the base body 1 through the positioning members, and the fixing plate 63 is fixedly mounted to the blocking plate 3 or the outer convex plate 4 through the positioning members. The positioning members include a first bolt 13 and a second bolt 14. The blocking plate 3 and the outer convex plate 4 are respectively fixedly connected to the base body 1 through the first bolt 13, and the fixing plate 63 is fixedly connected to the blocking plate 3 or the outer convex plate 4 through the second bolt 14.

[0060] Specifically, after the blocking plate 3 or the outer convex plate 4 is fixedly connected to the seat body 1 by the first bolt 13, the staff can place the sponge body 62, the arc-shaped thin plate 66 and the fixing plate 63 in sequence, and finally install them through the second bolt 14. The purpose of this design is that when the sponge body 62 needs to be replaced, it is only necessary to remove the second bolt 14 to replace it, without the need to remove too many positioning parts, reducing the tedious process while avoiding the problem of instability of the double-row bearings 2 inside the seat body 1 caused by repeated disassembly of the blocking plate 3.

[0061] The working principle and use process of this utility model:

[0062] Before use, after the double-row bearing 2 is installed in the inner cavity of the seat body 1, the sealing plate 3 can be clamped on the front end face of the seat body 1, and then the sealing plate 3 can be fixed and installed by the first bolt 13 to ensure the stable setting of the double-row bearing 2. Then the water absorption component 6 can be installed, and the outer convex plate 4 and the water absorption component 6 on the outer convex plate 4 can be installed according to the actual working conditions. After the seat body 1 is installed, the staff will fix the optical axis fixing ring 51 on the shaft body, and ensure that one end of the extrusion rod 54 can be subjected to the force of the tension spring 53 to resist the fixing plate 63.

[0063] During use, the bearing seat is made of stainless steel, which can automatically form a dense passivation film in a humid environment, effectively blocking the erosion of water vapor, oxygen and other corrosive media, greatly improving the overall corrosion resistance of the bearing seat, and avoiding deformation and other problems due to inability to bear loads after corrosion weakening; at the same time, the double-row bearings 2 inside the seat body 1 are used to make the bearing seat body bear greater radial force and axial force, and adapt well to the complex stress conditions such as vibration and eccentric load that may occur in the equipment in a humid environment, effectively disperse the load, reduce a certain wear rate, and improve the working reliability of the bearing seat body in a humid and harsh environment; and when the bearing seat body is used for a long time, when external water vapor or splashing water droplets enter the bearing seat body, the sponge 62 can absorb the incoming moisture to avoid moisture erosion of the double-row bearings 2 and the inner cavity of the seat body 1, and the sponge 6 After absorbing water, the shaft body rotates, and the shaft body can drive the optical axis fixing ring 51 to rotate. After the optical axis fixing ring 51 rotates, the squeezing rod 54 can be driven to rotate. Thus, when the squeezing rod 54 rotates, one end of the squeezing rod 54 can rotate on the fixing plate 63. When the squeezing rod 54 rotates into the squeezing opening 64, the squeezing rod 54 can squeeze the arc-shaped thin plate 66 with the help of the force of the tension spring 53. After the arc-shaped thin plate 66 is squeezed, it can squeeze the bottom end of the sponge 62. Then, after the sponge 62 is squeezed, the water squeezed out can be discharged outward through the drainage hole 65. Thus, under the continuous rotation of the shaft body, the squeezing rod 54 can repeatedly squeeze the water from the sponge 62, ensuring the long-term water absorption effect of the sponge 62, preventing the problem of water entering the inner cavity of the seat body 1 and corroding the double-row bearing 2. At the same time, the design of the arc-shaped thin plate 66 effectively avoids damage to the sponge 62, and has a certain reliability.

[0064] When the tension spring 53 is continuously opened and closed and the elastic force is reduced, the staff can manually rotate the sleeve 52 to disengage the sleeve 52 from the stepped guide hole 55 , and then the staff can replace the tension spring 53 to ensure the extrusion work of the extrusion rod 54 .
