Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, and more specifically, to a reaction vessel frame bearing connection structure and a reaction vessel. Background Technology

[0002] The ternary precursor material is nickel-cobalt-manganese hydroxide (Ni). x Co y Mn (1-x-y) (OH)₂ is produced from nickel, cobalt, and manganese salts. The ratio of nickel, cobalt, and manganese can be adjusted according to actual needs, and the finished product is a solid powder. The reaction vessel provides a reaction site for nickel-cobalt-manganese hydroxide, allowing for precise temperature and rate control and regulation of product morphology.

[0003] In daily production environments, reactor frame bearings can be damaged due to lubrication issues, installation gaps leading to stress imbalances, impurity intrusion, natural wear and tear, and prolonged overload operation. Reactor bearings and drive shafts typically use an interference fit and are installed inside the mechanical equipment. When maintenance or replacement is required after a service life, disassembly and removal are extremely difficult. Currently, tools such as pry bars and chisels are commonly used for disassembly, or destructive disassembly methods are employed. These methods are not only difficult to operate and prone to damaging or even rendering parts unusable, but also inefficient and disrupt production operations.

[0004] Therefore, there is an urgent need to improve the disassembly method of bearings in order to improve the quality of maintenance and reduce maintenance time. Utility Model Content

[0005] The purpose of this utility model is to provide a reactor frame bearing connection structure and reactor, which can more easily disassemble the frame main shaft, improve maintenance quality and reduce maintenance time.

[0025] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0026] In addition, for ease of understanding, the technical terms involved in the embodiments of this utility model are explained in detail in the table below: Spindle: It is the core component in a machine that transmits the main motion and power, and it needs to rotate at high speed and with high precision.

[0027] Bearings are the basic components that support the spindle and can withstand the radial and axial loads on the spindle and its transmission components.

[0028] The following detailed description of the reactor frame bearing connection structure and overall structure, working principle, and technical effects of the reactor provided by this utility model, through embodiments and in conjunction with the accompanying drawings, is a practical example.

[0029] Please refer to Figure 1 and Figure 2 This utility model provides a reactor frame bearing connection structure, including: frame body 110, frame main shaft 121, transmission screw 130 and baffle 140.

[0030] The frame body 110 includes a base plate 111, on which mounting holes 112 are provided for the transmission screw 130 to pass through. The frame spindle 121 is installed inside the frame body 110 and is clearance-fitted with the bearing 122. Figure 2 The bearing 122 refers to the bearing housing. The spindle 121 is press-fitted with the bearing 122 due to thermal expansion during rotation. When maintenance is required, it can be detached from the bearing 122. The baffle 140 is installed between the bottom plate 111 and the bottom of the frame spindle 121. The baffle 140 is provided with a threaded hole 141 that mates with the transmission screw 130. The transmission screw 130 passes through the mounting hole 112 on the bottom plate 111 and the threaded hole 141 on the baffle 140 in sequence. When disassembling the frame spindle 121, it holds the frame spindle 121 against it. By controlling the movement of the transmission screw 130, the frame spindle 121 is detached from the bearing 122.

[0031] It should be noted that when maintenance or replacement is required, the main shaft 121 of the frame is often disassembled using tools such as pry bars and chisels, or by destructive disassembly. These methods are inefficient and can easily damage or even render parts unusable. This invention utilizes the cooperation between the transmission screw 130, the base plate 111, and the baffle 140. By rotating the transmission screw 130, it can move up and down. When the transmission screw 130 moves upward, it can abut against the main shaft 121, causing the shaft to be stressed and disengaged from the bearing 122. This avoids the deformation of the shaft caused by hammering.

[0032] In some embodiments, the frame body 110 further includes a top plate 113 and support columns 114 located between the top plate 113 and the bottom plate 111. One end of the support column 114 is connected to the top plate 113, and the other end is connected to the bottom plate 111, serving a supporting function. There can be multiple support columns 114, such as 2, 4, 6, 8, or 10, etc., with no specific limit on the number. The top plate 113 can have holes with a diameter larger than that of the frame spindle 121 to facilitate the installation and removal of the frame spindle 121.

[0033] Furthermore, the frame body 110 also includes at least one reinforcing plate 115 for connecting multiple support columns 114. The reinforcing plate 115 is located between the top plate 113 and the bottom plate 111, and the multiple support columns 114 are connected by the reinforcing plate 115 to increase the support strength. The number of reinforcing plates 115 is not limited, such as multiple from top to bottom, specifically two, but not limited to this. Specifically, mounting holes that mate with the support columns 114 can be provided on the reinforcing plate 115, through which the support columns 114 pass, or the support columns 114 can be welded to the reinforcing plate 115.

[0034] In some embodiments, to better control the up-and-down movement of the drive screw 130, the reactor frame bearing connection structure further includes a first rotating nut 151. The first rotating nut 151 is mounted on the drive screw 130 and located between the baffle 140 and the bottom of the frame main shaft 121. The drive screw 130 engages with the first rotating nut 151 and screws in. When the first rotating nut 151 screws in, the drive screw 130 moves axially, causing the shaft to disengage from the bearing.

[0035] Specifically, the mounting hole 112 on the base plate 111 is larger than the drive screw 130, and the threaded hole 141 of the baffle 140 can be internally threaded, engaging with the external thread of the drive screw 130. The baffle 140 can be made of cast steel, which has the advantages of high strength and impact resistance. The drive screw 130 and the first rotating nut 151 can be made of carbon steel, which has high strength.

[0036] The baffle 140 can be parallel to the base plate 111 of the frame body 110, or it can be not completely parallel.

[0037] In some embodiments, a support rod 143 is also included. One end of the support rod 143 is connected to the baffle 140, and the other end is connected to the base plate 111 of the frame body 110. The support rod 143 is used to connect the baffle 140 and the base plate 111, and can be fixed by welding, but is not limited to this method. Specifically, the support rod 143 can also be made of cast steel, which has the advantages of high strength and impact resistance. The length of the support rod 143 can be varied according to the size of the frame, and can be matched with the dimensions of the frame.

[0038] In an alternative implementation, there are at least two support rods 143.

[0039] It should be added that the bearing connection structure of the reactor frame can utilize a nut wrench to extend the torque, making it more labor-saving and efficient, and reducing damage to the original shaft and bearings. During operation, box wrenches and adjustable wrenches can be used, and extended arms can be used depending on the disassembly requirements.

[0040] This utility model embodiment also provides a reaction vessel, including the reaction vessel frame bearing connection structure provided in this utility model embodiment, and may further include a reaction vessel body, which is used to hold reaction raw materials, such as the synthesis raw materials for ternary precursor materials. The reaction vessel body may be located in... Figure 1 Below the middle structure, the upper coupling of the reactor is connected to the end coupling of 121. The motor spindle is connected to 113, causing the motor to drive the frame spindle 121 to rotate, thereby driving the stirring inside the reactor to rotate.

[0041] Specifically, the shape of the reactor body is not limited, and all existing reactor body shapes are within the protection scope of this utility model.

[0042] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
