Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary systems for refrigeration equipment, and specifically refers to a wastewater treatment mechanism for a refrigeration machine. Background Technology

[0002] In the rubber industry, rubber refrigeration machines are used to cool rubber products to achieve shaping. During the cooling process, wastewater containing rubber debris, particles and other impurities is generated. The treatment of this wastewater is an important part of ensuring environmental compliance in production and avoiding blockage of refrigeration system pipelines.

[0003] However, existing wastewater treatment methods for rubber chillers have significant problems. For example, some rubber chillers use pipe filters to intercept impurities, but these filters are prone to clogging and require disassembly and cleaning of the pipes, affecting equipment operation. Others use sedimentation tanks for natural settling, but cleaning these tanks requires emptying them, which is time-consuming, wasteful of water, and has low settling efficiency. Therefore, there is an urgent need for a wastewater treatment system for chillers that is simple to operate for impurity removal and has high solid-liquid separation efficiency. Utility Model Content

[0004] This invention divides the treatment chamber into a sedimentation chamber and a drainage chamber by using an overflow baffle. A movable impurity collection basket is provided below the sludge inlet of the sedimentation chamber, and the top of the overflow baffle is lower than the opening of the basket. Combined with the sludge discharge port of the drainage chamber, solid-liquid separation of rubber wastewater and convenient cleaning of impurities are achieved, thereby solving the problems mentioned in the background art.

[0005] The purpose of this utility model is achieved as follows: a wastewater treatment mechanism for a refrigeration machine includes a body with a water passage chamber, and further includes:

[0006] The treatment chamber has a sludge inlet at the top that communicates with the water passage chamber, and an openable and closable pick-up and drop-off cover at the rear.

[0007] An overflow baffle is fixed inside the treatment chamber and divides its interior into an interconnected sedimentation chamber and a drainage chamber.

[0008] An impurity collection basket is movably disposed within the sedimentation chamber and located below the wastewater inlet, for receiving incoming wastewater.

[0009] A drain outlet is located at the bottom of the drainage cavity and is used to connect to an external drainage system;

[0010] The top of the overflow baffle is lower than the opening of the impurity collection basket.

[0011] The present invention is further configured to include:

[0012] A handle is located on the rear side of the impurity collection basket;

[0013] A pair of sliding rollers are located at the bottom of the impurity collection basket;

[0014] A guide rail is located at the bottom of the sedimentation chamber along the front-to-back direction, used to allow the impurity collection basket to slide into the sedimentation chamber via sliding rollers.

[0015] The present invention is further provided that the guide rail is provided with a limiting groove for restricting the movement of the sliding roller.

[0016] The present invention is further provided that the outer end of the guide rail is provided with a guide slope.

[0017] The present invention is further configured such that the impurity collection basket has a funnel-shaped structure that gradually decreases in size from its open end downwards.

[0018] The present invention is further configured such that a snap-fit ​​block is fixed on the front side of the impurity collection basket, and the snap-fit ​​block has a slot that matches the top of the overflow baffle.

[0019] The present invention is further provided that the impurity collection basket is provided with at least one horizontally arranged baffle.

[0020] By adopting the above technical solution, the beneficial effects that this utility model can achieve are:

[0021] 1. By designing the top of the overflow baffle to be lower than the opening of the collection basket, solid impurities are trapped in the collection basket when sewage is injected, and the supernatant passes through the baffle and enters the drainage chamber, thus achieving solid-liquid separation and improving sewage treatment efficiency.

[0022] 2. By combining the impurity collection basket with the horizontal baffle, the baffle buffers the sewage flow rate and prevents impurities from spreading, while the funnel-shaped collection basket gathers impurities, thus improving the impurity interception effect.

[0023] 3. The locking block on the front side of the impurity collection basket cooperates with the overflow baffle, and the slot of the locking block fits into the top of the baffle, which avoids leakage of impurities through gaps and improves the reliability of solid-liquid separation.

Detailed Implementation

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1-3 :

[0029] Example 1:

[0030] This embodiment provides a wastewater treatment mechanism for a refrigeration unit, including a body 1 with a water passage chamber 2, and further comprising:

[0031] The treatment chamber 3 has a sewage inlet 4 at the top that communicates with the water passage chamber 2, and an openable and closable pick-up and drop-off cover 5 at the rear.

[0032] An overflow baffle 6 is fixed inside the treatment chamber 3 and divides its interior into a sedimentation chamber 7 and a drainage chamber 8 that are interconnected.

[0033] An impurity collection basket 9 is movably disposed within the sedimentation chamber 7 and located below the sewage inlet 4, for receiving incoming sewage.

[0034] A drain outlet 10 is located at the bottom of the drain cavity 8 and is used to connect to an external drainage system;

[0035] The top height of the overflow baffle 6 is lower than the opening height of the impurity collection basket 9.

[0036] The main body 1 is used to carry the sewage flow channel, which can guide the sewage generated by the refrigeration unit into the treatment chamber 3 in an orderly manner, and avoid the sewage from leaking or diverting during the transmission process. It has a hollow water passage chamber 2 inside, which has a connection structure that matches the sewage inlet interface 4 of the treatment chamber 3 to ensure the connection is sealed. The sewage outlet of the water passage chamber 2 can be connected to the sewage inlet interface 4 of the treatment chamber 3 through a pipe thread, and the pipe is equipped with a valve to control the sewage flow.

[0037] The treatment chamber 3 provides a closed space for solid-liquid separation of sewage, and also accommodates components such as overflow baffle 6 and impurity collection basket 9. It can ensure that sewage does not overflow during the separation process, provide a stable installation and working environment for each component, and prevent external debris from entering and affecting the separation effect. Its structure is a rectangular closed cavity with a sewage inlet 4 at the top and a pick-up and drop cover 5 hinged at the rear. The overflow baffle 6 is vertically fixed inside. It is connected to the bottom of the body 1 with a water passage chamber 2. The sewage inlet 4 at the top is directly opposite the outlet of the water passage chamber 2 of the body 1. The sewage outlet 10 is provided at the bottom corresponding to the position of the drainage chamber 8. The top is fixedly connected to the water passage chamber 2 of the body 1 through the sewage inlet 4. The whole is fixed to the ground by brackets or bolts.

[0038] The access cover 5 is used to open or close the opening on the rear side of the treatment chamber 3, providing an operating channel for the removal, cleaning and return of the impurity collection basket 9. When closed, it seals the treatment chamber 3 to prevent sewage from overflowing and external debris from entering. Its structure is a cover plate that is completely matched with the size of the access opening on the rear side of the treatment chamber 3. Its shape is consistent with the access opening on the rear side of the treatment chamber 3, mostly rectangular. It is hinged to one edge of the access opening on the rear side of the treatment chamber 3 by a hinge, and can be flexibly rotated around the hinge to open and close. After closing, it can also be locked to the treatment chamber 3 by a buckle or snap to ensure sealing and fixation.

[0039] The overflow baffle 6 divides the interior of the treatment chamber 3 into a sedimentation chamber 7 and a drainage chamber 8, while guiding the supernatant from the sedimentation chamber 7 to the drainage chamber 8. It has a flat plate structure, with the top height lower than the opening height of the impurity collection basket 9 to ensure that the supernatant can overflow smoothly. The side closer to the sludge inlet 4 is the sedimentation chamber 7, and the side closer to the sludge outlet 10 is the drainage chamber 8. The edge of the overflow baffle 6 is fixed to the inner wall of the treatment chamber 3 by welding or bolts.

[0040] The sedimentation chamber 7 provides space for the initial retention of wastewater and the collection of solid impurities. It allows solid impurities in the wastewater to fall into the impurity collection basket 9 under the action of gravity, while allowing the liquid to be temporarily stored in the chamber until the liquid level reaches the top of the overflow baffle 6, preparing for the overflow of the supernatant. Its structure is an independent chamber separated by the overflow baffle 6 in the treatment chamber 3. The bottom of the chamber is flat to place the impurity collection basket 9. It is connected to the drainage chamber 8 through the top of the overflow baffle 6. The liquid can flow over the top, while solid impurities are intercepted by the collection basket or cannot pass through due to their own gravity.

[0041] The drainage chamber 8 is used to contain the supernatant overflowing from the sedimentation chamber 7 and guide the supernatant to be discharged to the external drainage system. Its structure is an independent chamber separated by the overflow baffle 6 in the treatment chamber 3. The bottom of the chamber is provided with a drain port 10, the top is connected to the sedimentation chamber 7 through the top of the overflow baffle 6 to receive the supernatant, and the bottom discharges the supernatant through the drain port 10. The supernatant is discharged to the external drainage system and can be directly treated as wastewater or recycled after filtration.

[0042] The impurity collection basket 9 is used to collect solid impurities in the sewage flowing in from the sewage inlet 4, realizing centralized collection of impurities and physically separating solid impurities from liquids, which is convenient for subsequent removal and cleaning and reduces maintenance difficulty. Its structure is a basket-shaped structure with a bottom and side walls, and its shape is designed as a cuboid or cube. Its height must be lower than the top height of the overflow baffle 6 to prevent impurities from overflowing with the supernatant. It can be movably placed inside the sedimentation chamber 7, and its open end is directly facing the bottom opening of the sewage inlet 4 to ensure that sewage flows directly into the basket. There is no fixed connection structure. It is placed stably at the bottom of the sedimentation chamber 7 by its own weight. It can be directly removed or put back without tools, which is convenient for daily cleaning operations.

[0043] In the above design, wastewater generated during the operation of the chiller is directly injected into the sedimentation chamber 7 of the treatment chamber 3 through the inlet port 4 at the top of the treatment chamber 3, and the wastewater falls into the impurity collection basket 9 inside the sedimentation chamber 7. Solid impurities in the wastewater are deposited at the bottom of the basket. As wastewater continues to be injected, the liquid level in the sedimentation chamber 7 gradually rises. When the liquid level reaches the top height of the overflow baffle 6, since the top height of the overflow baffle 6 is lower than the opening height of the impurity collection basket 9, the impurities in the collection basket will not overflow with the liquid. The supernatant flows over the top of the overflow baffle 6 and into the drainage chamber 8 of the treatment chamber 3. After the supernatant entering the drainage chamber 8 is temporarily stored in the chamber, it flows naturally into the external drainage system through the drain port 10 at the bottom of the drainage chamber 8, completing the solid-liquid separation and discharge of the wastewater. When a certain amount of solid impurities accumulate in the impurity collection basket 9, the removal cover 5 on the rear side of the treatment chamber 3 is opened, the impurity collection basket 9 in the sedimentation chamber 7 is taken out, the solid impurities inside are cleaned, and then the collection basket is put back into the sedimentation chamber 7. The removal cover 5 is then closed, and the normal operation of the wastewater treatment mechanism is restored.

[0044] The system also includes a handle 11 located at the rear of the impurity collection basket 9, a pair of sliding rollers 12 located at the bottom of the impurity collection basket 9, and guide rails 13 located at the bottom of the sedimentation chamber 7 along the front-to-back direction for allowing the impurity collection basket 9 to slide into the sedimentation chamber 7 via the sliding rollers 12. The purpose of this design is to improve the convenience and stability of impurity cleaning by optimizing the handling structure of the impurity collection basket 9. Specifically, a plate-shaped or rod-shaped handle 11 is welded or bolted to the rear of the impurity collection basket 9 for easy gripping by the operator. A pair of sliding rollers 12 are symmetrically installed at the bottom of the basket, and the sliding rollers 12 are rotatably connected to a pre-set mounting base at the bottom of the collection basket via a rotating shaft. Simultaneously, two long, strip-shaped guide rails 13 are integrally formed along the front-to-back direction at the bottom of the sedimentation chamber 7. The rail cross-section is grooved to fit the sliding rollers 12 and form a sliding pair with them. When impurities need to be cleaned, the operator can grip the handle. Applying force to the handle 11 allows the impurity collection basket 9 to slide smoothly along the guide rail 13 via the sliding rollers 12 at the bottom, and the basket can be quickly pulled out of the sedimentation chamber 7, thus achieving a movable function. After cleaning, the basket can be pushed back to its original position along the rail. There is no need to carry or disassemble parts, which reduces the operational intensity of impurity cleaning, and the guiding effect of the rail on the rollers ensures that the basket is not easily deviated when being picked up or put down, ensuring the accurate relative position of the impurity collection basket 9 with the sedimentation chamber 7 and the overflow baffle 6, and maintaining the stable operation of the sewage treatment mechanism.

[0045] The guide rail 13 is provided with a limiting groove 14 for restricting the movement of the sliding roller 12. The purpose of the above design is to further improve the stability of the impurity collection basket 9 in sliding and stopping within the sedimentation chamber 7, and to avoid misalignment of the basket due to roller displacement during the loading and unloading process. Specifically, a limiting groove 14 adapted to the sliding roller 12 is integrally formed on the elongated guide rail 13 fixed to the bottom of the sedimentation chamber 7 in the front-to-back direction. The limiting groove 14 has a U-shaped or arc-shaped groove structure that matches the outer arc of the roller. The groove width is slightly larger than the roller diameter to accommodate the roller, and the groove depth ensures that the roller is not easily dislodged after being embedded. When the impurity collection basket 9 moves along the guide rail 13 via the sliding roller 12 at the bottom, the roller is embedded in the limiting groove 14 at a preset position, thereby preventing the impurity collection basket 9 from deviating from the preset path during sliding, ensuring that the impurity collection basket 9 is always accurately positioned below the sewage inlet 4, maintaining a correct fit with the overflow baffle 6, and ensuring the stability of solid-liquid separation during sewage treatment.

[0046] The outer end of the guide rail 13 is provided with a guide slope 15. The purpose of the above design is to reduce the operational difficulty when the impurity collection basket 9 is returned to the sedimentation chamber 7 and to ensure that the sliding roller 12 can smoothly enter the guide rail 13. Specifically, at the outer end of the long strip-shaped guide rail 13 fixed to the bottom of the sedimentation chamber 7 in the front-back direction, that is, on the side near the handling chamber 3 pick-up and drop cover 5, a guide slope 15 is formed by grinding or welding. The guide slope 15 has an inclined structure that transitions from the outer edge of the rail to the top surface of the rail. The slope and the top surface of the rail form a smooth angle, and the length is sufficient to guide the roller. When the operator pushes the cleaned impurity collection basket 9 back to the sedimentation chamber 7, it can easily slide smoothly into the guide rail 13 along the guide slope 15. This not only improves the convenience of picking up and dropping the impurity collection basket 9, but also avoids damage to the roller or rail caused by hard contact, ensuring the service life and operational stability of the overall structure.

[0047] The impurity collection basket 9 has a funnel-shaped structure that gradually decreases in size from its open end downwards. The purpose of this design is to optimize the interception and aggregation effect of solid impurities in wastewater by the impurity collection basket 9, while facilitating subsequent cleaning of impurities. The funnel-shaped structure of the impurity collection basket 9 allows solid impurities to naturally converge towards the bottom of the basket under the guidance of gravity and the inclined sidewalls when wastewater flows into the basket from the inlet port 4, reducing the adhesion and accumulation of impurities on the inner side of the basket wall and avoiding blockage of the permeable holes due to impurity dispersion. At the same time, the funnel-shaped contraction shape allows the operator to directly pour out the impurities gathered at the bottom from the open end at once when cleaning impurities, without having to clean each area of ​​the basket one by one, simplifying the cleaning operation. In addition, the downward contraction structure can reduce the space occupied at the bottom of the basket without reducing the opening receiving area, making the basket more suitable for the installation layout of the sedimentation chamber 7 and ensuring the compactness of the overall structure.

[0048] A snap-fit ​​block 16 is fixed to the front side of the impurity collection basket 9. The snap-fit ​​block 16 has a slot 17 that matches the top of the overflow baffle 6. The purpose of the above design is to fix the position of the impurity collection basket 9 in the sedimentation chamber 7. Specifically, on the front side of the funnel-shaped impurity collection basket 9, that is, the side close to the overflow baffle 6, a block-shaped snap-fit ​​block 16 is fixed by welding or bolting. The snap-fit ​​block 16 has a rectangular or arc-shaped block structure that matches the curvature of the front side of the basket. It has a slot 17 on the side facing the overflow baffle 6. The slot 17 matches the top of the overflow baffle 6, forming a concave structure that can fit into the top of the overflow baffle 6. When the impurity collection basket 9 is placed into the sedimentation chamber 7, the slot 17 of the snap-fit ​​block 16 will fit tightly into the top of the overflow baffle 6. This fitting relationship can position the impurity collection basket 9, prevent the impurity collection basket 9 from shifting in the sedimentation chamber 7 due to water flow impact, and ensure that the impurity collection basket 9 is always directly below the sludge inlet 4, thus ensuring the stability of solid-liquid separation.

[0049] The impurity collection basket 9 is equipped with at least one horizontally arranged baffle 18. The purpose of this design is to slow down the flow rate of sewage in the impurity collection basket 9, prevent the water flow from being too rapid and causing fine solid impurities to overflow into the drainage chamber 8, and at the same time promote the settling of impurities in the basket. Specifically, inside the impurity collection basket 9, at least one flat baffle 18 is fixed horizontally by welding or bolts. The shape of the baffle 18 is mostly rectangular with edges adapted to the inner wall of the impurity collection basket 9, located near the opening end of the impurity collection basket 9 and on the side close to the overflow baffle 6. When impurities may be carried into the drainage chamber 8 by the water flow, they are blocked by the baffle 18, which improves the impurity interception effect and maintains the stable operation of the sewage treatment device.

[0050] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
