Description

Technical Field

[0001] This utility model relates to the field of quenching cooling pool technology, specifically a sprocket quenching cooling pool with easily cleanable residue. Background Technology

[0002] Sprocket quenching is a common step in heat treatment processes. It typically involves rapidly cooling the high-temperature sprocket in a cooling tank to improve the surface hardness and wear resistance of the material. During sprocket quenching, carbides, oxide scale, and some detached particles continuously deposit at the bottom of the cooling tank, causing the impurity concentration in the quenching fluid to increase. This reduces cooling efficiency and affects the quality of subsequent workpiece processing. Therefore, timely and efficient removal of quenching residue is a key technical aspect of quenching tank structural design.

[0003] In existing technologies, sprocket quenching equipment mostly adopts a vacuum-type slag discharge structure. This involves manually or automatically pumping the quenching liquid out of the cooling tank, followed by manual cleaning of the residue at the bottom of the tank or centralized discharge via a mechanical conveying device. Some structures also use filter frames and slag collection nets to assist in collection, but the entire system still requires periodic shutdowns. Furthermore, to avoid fluctuations in the quenching effect caused by agitation of the liquid surface, these systems often separate residue cleaning from the quenching operation, resulting in a significant downtime dependency between the slag discharge process and the quenching operation.

[0004] Existing sprocket quenching cooling pool technology employs a bottom settling chamber structure with a filter plate, along with a removable filter screen for residue collection and periodic evacuation. However, in actual use, the filter screen is prone to clogging, slag removal is incomplete, and the quenching liquid still needs to be completely drained before cleaning, making the operation complex and inefficient, which is not conducive to the requirements of continuous quenching processes.

[0005] In summary, existing sprocket quenching cooling tanks generally suffer from problems such as requiring machine shutdown for slag removal, cumbersome cleaning procedures, non-adjustable slag removal volume, and poor slag removal synchronization, which limit the equipment's efficiency and automation level. Therefore, there is an urgent need to provide a quenching slag cleaning structure that does not require evacuation of the quenching fluid, has online slag removal capabilities, and has an adjustable volume, in order to improve the continuity of the sprocket heat treatment process and the efficiency of slag removal. Utility Model Content

[0006] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0007] Therefore, the technical solution adopted by this utility model is as follows: a sprocket quenching cooling pool with easy-to-clean residue, comprising: a cooling pool body, a rotating chamber, a main rotating roller, and an eccentric guide assembly. The cooling pool body is used to contain the quenching medium and is located at the bottom of the entire device structure. The rotating chamber is located at the bottom of the cooling pool body and is connected to it, used to receive the residue generated during the quenching process. One end of the rotating chamber is provided with a cover. The main rotating roller is rotatably disposed inside the rotating chamber along the axial direction. Multiple slag hoppers are arranged on the outside of the main rotating roller. Each slag hopper is slidably installed with a discharge plug plate. An eccentric guide assembly is provided on the inside of the main rotating roller to drive each discharge plug plate to move radially.

[0008] Specifically, the rotating chamber is a hollow cylindrical structure with a slag inlet and a discharge outlet on its outer surface. The slag inlet is connected to the bottom of the cooling pool to guide the deposited slag into the interior of the rotating chamber, and the discharge outlet is located on the opposite side to discharge the residue from the rotating chamber.

[0009] In a preferred embodiment, the main rotating roller is further configured with a drive system on the outside of the rotating drum chamber for indexing rotation. The drive system includes a motor and an indexing gearbox. The indexing angle is consistent with the arrangement angle of the slag hopper on the main rotating roller, which is used to achieve precise indexing operation.

[0010] Specifically, this structure enables the main roller to rotate intermittently, and each slag hopper sequentially enters the corresponding position of the slag inlet and outlet, thereby realizing the function of receiving and discharging slag position by position.

[0011] In a preferred embodiment, the eccentric guide group is further configured such that during the indexing rotation of the main roller, the eccentric guide group remains stationary. The eccentric guide group includes a fixed shaft rod, a pulley, and an eccentric groove arranged on the surface of the pulley. The pulley is slidably installed between the cover and the inner wall of the rotating drum chamber through a bearing. The end of the fixed shaft rod passes through the cover and is provided with an adjusting fastener. The two ends of the guide pin rod are sleeved on the inner side of the pulley and slide along the eccentric groove, thereby driving the discharge plug plate to reciprocate within the slag hopper chamber during the rotation of the main roller.

[0012] Specifically, the structure utilizes the relative rotation between the main rotating roller and the eccentric guide group to achieve automatic opening and closing of the discharge plug plate, thereby completing the collection and discharge of residue.

[0013] In a preferred embodiment, each discharge plug is further configured such that a dynamic sealing element is provided on the outer periphery of each discharge plug plate to fit against the inner wall of the slag hopper, forming a sliding seal during the radial sliding of the plug plate, effectively preventing leakage of the quenching medium and enhancing the sealing performance and operational stability of the internal structure.

[0014] Specifically, the dynamic sealing structure can prevent quenching liquid from seeping into the internal mechanical component area during slag discharge, thus extending the service life of the components.

[0015] In a preferred example, the configuration is further as follows: there are two pulleys, which are symmetrically arranged on both sides of the fixed shaft, and the two ends of the guide pin are respectively sleeved on the inner side of the two pulleys to realize bidirectional stable guidance of the plug plate structure.

[0016] Specifically, this structure improves the synchronization and precision of the discharge mechanism, ensuring that the discharge actions of multiple slag hoppers are coordinated and consistent.

[0017] In a preferred example, the bottom of the cooling pool cavity is sloping to guide the deposited residue to slide into the slag inlet, thus preventing residue accumulation and a decrease in discharge efficiency.

[0018] Specifically, the structure combines gravity flow to guide the residue into the rotating chamber, making residue cleaning more efficient and reliable.

[0019] The beneficial effects achieved by this utility model are as follows: 1. In this utility model, by connecting the bottom of the cooling pool body and the rotating drum structure, and with the indexing rotation of the main rotating roller and the internal guidance of the eccentric guide group, the automatic sedimentation, conveying and discharge of slag material is realized. The entire slag discharge process can be carried out without evacuating the quenching liquid, and it has the ability to operate online and discharge slag, which significantly improves the continuity and work efficiency of the quenching station.

[0020] 2. In this utility model, the discharge plug plate inside the main roller is guided by an eccentric sliding groove structure to achieve radial stroke adjustment. With the help of adjusting fasteners to control the eccentricity, the volume of each slag hopper can be flexibly adjusted according to the amount of slag deposited, adapting to the slag treatment needs under different working conditions. It has the advantages of strong structural self-adaptability and high slag discharge stability. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0024] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of this invention.

[0025] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a sprocket quenching cooling pool with easily cleanable residue.

[0026] Combination Figures 1-5 As shown, the present invention provides a sprocket quenching cooling pool with easy-to-clean residue, comprising a cooling pool body 100, a rotating chamber 200, a main rotating roller 300, and an eccentric guide group 400.

[0027] The cooling tank 100 is used to contain the quenching medium. It is located at the bottom of the entire device structure and has a trough-type structure. The bottom of its inner cavity is inclined, which can guide the settled quenching slag to the slag inlet 201 set on one side, ensuring that the residue is concentrated and guided into the discharge structure, thereby improving the slag discharge efficiency.

[0028] In this embodiment, the rotating chamber 200 is located at the bottom of the cooling pool 100 and has a hollow cylindrical structure. A slag inlet 201 and a discharge port 202 are respectively provided on both sides of its outer shell. The slag inlet 201 communicates with the bottom channel of the cooling pool 100 to receive quenching residue, and the discharge port 202 is used to discharge the residue from the rotating chamber 200. A cover 210 is provided at one end of the rotating chamber 200. The cover 210 is a detachable structure, facilitating the inspection and replacement of the internal components.

[0029] In this embodiment, the main rotating roller 300 is located inside the rotating drum chamber 200 and is arranged along the axis of the rotating drum. It is driven by a drive system located outside the rotating drum chamber 200 to achieve indexing rotation. The drive system includes a motor and an indexing gearbox installed outside the rotating drum chamber 200. The indexing angle is consistent with the interval angle of the cover 210 to ensure accurate alignment of each slag hopper chamber 310.

[0030] In this embodiment, multiple slag hoppers 310 are provided on the outer side of the main rotating roller 300. The multiple slag hoppers 310 are evenly spaced along the outer circumference of the main rotating roller 300 and are used to receive and temporarily store the sprocket quenching residue entering from the slag inlet 201. A discharge plug plate 320 is slidably installed on the inner side of each slag hopper 310. Each discharge plug plate 320 is arranged one-to-one in the slag hopper 310, and a dynamic sealing element is provided on the outer periphery of the discharge plug plate 320 to fit against the inner wall of the slag hopper 310, effectively preventing the quenching liquid from leaking through the gaps.

[0031] In this embodiment, the eccentric guide assembly 400 is disposed inside the main rotating roller 300, and includes a fixed shaft rod 410, pulleys 420, and an eccentric groove 421 arranged on the surface of the pulleys 420. The fixed shaft rod 410 is fixedly connected to the inner side of the cover 210, passes through the rear end of the cover 210, and is provided with an adjusting fastener for adjusting the eccentricity. There are two pulleys 420, which are respectively arranged on the left and right sides of the fixed shaft rod 410 to form a symmetrical fit structure. The outer circular surface of the pulleys 420 is rotatably supported on the inner wall bearing seats of the cover 210 and the rotating drum 200. The eccentric guide assembly 400 is located inside the main rotating roller 300, and one end is driven to drive the internal discharge mechanism to perform periodic unloading operations.

[0032] Furthermore, each discharge plug plate 320 is fixedly connected to one end with a guide pin 321. The two ends of the guide pin 321 are slidably sleeved on the inner side of the two pulleys 420 and slide along the circumferential direction of the eccentric groove 421. Guided by the eccentric structure of the pulleys 420 during the rotation of the main roller 300, the guide pin 321 drives the discharge plug plate 320 to reciprocate along the radial direction of the slag hopper 310.

[0033] During operation, the main roller 300 rotates in stages under the drive system, while the eccentric guide assembly 400 remains stationary. Through the offset action of the pulley 420 and the eccentric groove 421, the discharge plug plate 320 reciprocates radially within the slag hopper 310. Due to the eccentric structure of the eccentric groove 421, the guide pin 321 slides relative to the pulley 420 during the rotation of the main roller 300, thereby driving the discharge plug plate 320 to slide radially within the slag hopper 310. When the slag hopper 310 rotates to the position corresponding to the slag inlet 201, the discharge plug plate 320 is slid to the inner side, opening the receiving space to receive quenching slag. When the slag hopper 310 continues to rotate to the position corresponding to the discharge port 202, the discharge plug plate 320 is guided out, opening the bottom of the slag hopper 310, allowing the quenching residue to be dumped and discharged.

[0034] By adjusting the adjusting fastener on the cover 210, the eccentric distance between the fixed shaft rod 410 and the pulley 420 can be adjusted, thereby changing the sliding amplitude of the guide pin rod 321 and further controlling the stroke of the discharge plug plate 320 to adapt to the discharge requirements of residues with different particle sizes or accumulation amounts.

[0035] Working principle and usage process of this utility model: During use, the main rotating roller 300 is driven to rotate in an indexing manner along the axial direction by a drive system located on the outside of the rotating drum 200. Multiple slag hoppers 310 located outside the main rotating roller 300 rotate sequentially. The residue generated after the quenching medium in the cooling tank 100 quenches the sprocket is slid down the inclined structure of the inner cavity of the cooling tank 100 under gravity and finally enters the rotating drum 200 through the slag inlet 201.

[0036] During the indexing rotation of the main roller 300, the eccentric guide group 400 inside it remains stationary. The eccentric groove 421 on the inner side of the pulley 420 guides the guide pin 321, driving the discharge plug plate 320 connected to the guide pin 321 to reciprocate in the radial direction.

[0037] When a slag hopper 310 rotates to the position corresponding to the slag inlet 201, the corresponding discharge plug 320 retracts inward under the action of the eccentric guide group 400, so that the slag hopper 310 forms a space to receive quenching residue.

[0038] During the continued rotation, when the slag hopper 310 moves to the position corresponding to the discharge port 202, the discharge plug plate 320 is driven outward by the eccentric structure of the pulley 420, thereby discharging the stored residue to the outside of the rotating drum 200.

[0039] During the slag discharge process, the dynamic sealing element on the outer periphery of the discharge plug plate 320 fits snugly against the inner wall of the slag hopper 310, achieving a sealing isolation during reciprocating sliding to prevent leakage of the quenching medium. By adjusting the eccentricity of the fit between the pulley 420 and the fixed shaft rod 410, the sliding stroke of the guide pin rod 321 in the eccentric groove 421 can be flexibly adjusted, thereby controlling the opening and closing range of the discharge plug plate 320 and the slag volume.

[0040] Through the above structure and operation mode, this utility model can realize the automatic reception, segmented and positional cleaning and directional discharge of residue in the cooling pool, improve the discharge efficiency of quenching residue, avoid the problem of frequent manual cleaning of traditional equipment, and has the characteristics of high operational stability, high cleaning efficiency and strong sealing.
