DETAILED DESCRIPTION

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0030] Example 1, reference Figures 1 to 9, which is the first embodiment of the present invention, and provides a waste oil continuous flocculation sedimentation and slag discharge device, which can achieve efficient and continuous treatment of waste oil, has significant technical effects and environmental protection significance, and includes a tank body 100, the tank body 100 includes a sedimentation area 101 and a slag discharge area 102, a sedimentation component 200 is arranged in the sedimentation area 101, a quick-release structure 300 is arranged between the tank body 100 and the sedimentation component 200, the sedimentation component 200 includes a plurality of inclined plate members 201, the inclined plate member 201 includes a frame body 202, a plurality of inclined plate boxes 203 are arranged in the frame body 202, a degradation zone 204 is formed between adjacent inclined plate boxes 203, and a frame body 202 is arranged outside There are multiple groups of reinforcement frames 205, and the reinforcement frames 205 press the multiple inclined plate boxes 203. The upper end surface of the reinforcement frame 205 is provided with a fixed frame 206. The quick-release structure 300 is arranged in the fixed frame 206. The quick-release structure 300 includes a fixing part 301 arranged on the outer wall of the tank body 100, and an inserting part 302 cooperating with the fixing part 301 is arranged in the fixing frame 206. A locking part 303 is arranged in the fixing part 301, and a toggle part 304 cooperating with the locking part 303 is arranged in the fixing part 301. An unlocking part 305 is arranged in the toggle part 304, and an auxiliary part 306 is arranged on the outer wall of the unlocking part 305. The auxiliary part 306 forms a secondary locking for the inserting part 302.

[0031] The prior art uses an integrally formed inclined plate box 203 to replace the traditional inclined plate when sedimentation treatment is performed on waste oil, thereby eliminating the need for side plates, dividing strips, and dividing strip fixing devices required for the installation of the inclined plate. At the same time, the present invention further improves the connection method between the sedimentation component 200 and the frame 202. A quick-release structure 300 is provided between the tank body 100 and the sedimentation component 200. The rapid positioning of the sedimentation component 200 is achieved by the cooperation of the insert 302 and the fixing component 301. At the same time, the device is secondary locked by the locking component 303 and the auxiliary component 306. In this way, there is no need to use complicated procedures such as screws and bolts to connect, and the installation is faster and more convenient.

[0032] Depend on Figure 1 It can be seen that the tank body 100 is placed vertically on the ground, and the tank body 100 is made of corrosion-resistant materials to withstand the waste oil and the chemical substances that may be produced during its treatment. The interior of the tank body 100 is designed with a reasonable flow channel to ensure that the waste oil flows evenly in the tank body 100. The tank body 100 includes a sedimentation area 101 and a slag discharge area 102, with an upper and lower two-layer structure, which has a better effect on the flocculant sedimentation and slag discharge process.

[0033] Specifically, a microfiltration membrane 203a is arranged outside the inclined plate box 203, a negative pressure chamber 203b is arranged inside the inclined plate box 203, a breathable core 203c is arranged inside the negative pressure chamber 203b, the microfiltration membrane 203a is arranged on the breathable core 203c, and one end of the negative pressure chamber 203b is connected to a negative pressure connector 203d.

[0034] Depend on Figure 5 It can be seen that the breathable core 203c has a number of uniform air holes, the microfiltration membrane 203a is laid flat on the breathable core 203c, and the breathable core 203c used in the structure is a sand core tooling, which has good air permeability uniformity. When in use, the negative pressure joint 203d generates suction, and the negative pressure sucks the microfiltration membrane 203a at this time, which can ensure that the pressure at each position of the microfiltration membrane 203a is uniform and realize the uniform suction of the microfiltration membrane 203a.

[0035] When the device is actually used, the flocculated waste oil is pumped into the tank 100, and the waste oil enters the middle tank and then goes down into the sedimentation area 101. After ensuring its flow coefficient, a small amount of impurities, sludge, and colloid will settle to the cone. The inclined plate settler structure can reduce the fluid Reynolds number and suppress turbulent disturbance, thereby accelerating the sedimentation process of the flocculants. In this process, a ceramic microfiltration membrane 203a or an organic microfiltration membrane 203a is embedded in the inclined plate. At the same time, the present invention adopts micro-negative pressure technology to quickly pull down the sludge, colloid, and asphalt and adsorb them on their surface. When the surface forms a certain thickness, the sludge will slide down with the inclined plate to the slag discharge area 102. At the same time, a new adsorption area will be formed on the surface after sliding down, and the adsorption will continue. The microfiltration membrane 203a embedded in the inclined plate will have relatively stubborn sediment attached to its surface during long-term operation.

[0036] In addition, the present invention further refines the sedimentation component 200 in the sedimentation area 101, and realizes locking of the device through the cooperation of the fixing part 301 and the plug-in part 302, as shown in Examples 2 and 3 for details. In this way, there is no need to use complicated procedures such as screws and bolts to connect, and the installation is faster and more convenient.

[0037] Example 2, reference Figures 1 to 9, which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a fixing member 301 of the waste oil continuous flocculation sedimentation and slag discharge device. The fixing member 301 includes two groups of fixing blocks 301a arranged on both sides of the outside of the tank body 100. The fixing blocks 301a are each provided with a fixing groove 301b. The inserting member 302 includes a plug rod 302a fixedly connected to the inner side of the fixing frame 206. The plug rod 302a is correspondingly pressed against the fixing groove 301b. A card groove 302b is provided on one side of the outer side of the plug rod 302a. A resisting block 302c is integrally formed at one end of the plug rod 302a. The locking member 303 includes a plug rod 302a rotatably connected to the fixing frame 206. The rotating shaft 303a in the groove 301b, the rotating shaft 303a is fixedly connected with a spring piece 303b, one end of the spring piece 303b abuts against the side wall of the fixed groove 301b, a locking block 303c is fixed on the outer wall of the rotating shaft 303a, a locking groove 303d is provided in the locking block 303c, a compression spring 303e is fixedly connected in the locking groove 303d, the compression spring 303e is a carbon spring with high strength and is convenient for daily work use, one end of the compression spring 303e is fixedly connected with a clamping block 303f, the clamping block 303f correspondingly abuts against the clamping groove 302b, and an arc block 303g is integrally formed on the outside of the locking block 303c.

[0038] Depend on Figures 6 to 8 It can be seen that the fixing block 301a is a rectangular parallelepiped with a fixing groove 301b on the inner side. The fixing groove 301b is in a convex shape, and the upper end of the convex shape has a larger opening, which is convenient for the docking of the plug-in component 302. The inner side of the fixing frame 206 is fixedly connected with an insertion rod 302a, and the insertion rod 302a can be divided into two upper and lower locking areas, one is the slot 302b on the side wall of the insertion rod 302a, and the other is the interference block 302c at the bottom of the insertion rod 302a. Example 2 explains the locking area of ​​the slot 302b, and the locking part of the interference block 302c is shown in Example 3.

[0039] A rotating shaft 303a is rotatably connected in the fixed groove 301b, and a locking block 303c is fixedly connected to the outer wall of the rotating shaft 303a. At the same time, the rotating shaft 303a is pressed against the inner wall of the fixed groove 301b through the spring piece 303b, and the spring piece 303b and the insertion rod 302a are not in the same plane, so there will be no movement interference. The spring piece 303b stores a certain elastic potential energy when locked. At the same time, a retractable card block 303f is arranged in the locking block 303c, and the head of the card block 303f is a wedge-shaped structure, so that when the insertion rod 302a enters the fixed groove 301b, the card block 303f is squeezed and retracts into the locking groove 303d. When the card slot 302b moves to the position of the card block 303f, the card block 303f correspondingly presses against the card slot 302b to complete the locking of the insertion rod 302a.

[0040] Specifically, the toggle member 304 includes a toggle rod 304a rotatably connected to the fixed groove 301b, a toggle plate 304b is fixedly connected to the outer wall of the toggle rod 304a, a notch 304c is provided on the outer wall of the toggle plate 304b, the arc block 303g is correspondingly abutted in the notch 304c, the outer wall of the toggle rod 304a is also provided with a surrounding groove 304d, and the unlocking member 305 includes a sleeve 305a provided on the outer wall of the toggle rod 304a, and the sleeve 305a is provided on the outer wall of the toggle rod 304a. 5a is provided with a positioning groove 305b, and a positioning block 305c is integrally formed in the positioning groove 305b. The positioning block 305c is correspondingly slidably connected in the surrounding groove 304d. One end of the sleeve 305a correspondingly passes through the fixing block 301a. A connecting plate 305d is fixedly connected between two adjacent groups of sleeves 305a. A screw 305e is threadedly connected to the middle position of the connecting plate 305d, and one end of the screw 305e is rotatably connected to the outer wall of the tank body 100.

[0041] Depend on Figures 5 to 9 It can be seen that the toggle rod 304a is rotatably connected to the lower part of the rotating shaft 303a, and a circular toggle plate 304b is fixedly connected to the outer wall of the toggle rod 304a. A trumpet-shaped notch 304c is provided in the toggle plate 304b. When the toggle plate 304b is rotated to a position corresponding to the arc block 303g, the arc block 303g is correspondingly pressed into the notch 304c, and the spring piece 303b is released, so that the locking block 303c rotates clockwise, so that the card block 303f can be separated from the card slot 302b, and the device can be used to rotate the toggle plate. The driving method of 304b is further refined, and a sleeve 305a is provided on the outer wall of the toggle rod 304a, and a surrounding groove 304d is provided on the outer wall of the toggle rod 304a. A positioning block 305c is provided in the sleeve 305a, and the positioning block 305c is correspondingly slidably connected in the surrounding groove 304d. When the screw rod 305e is rotated, the connecting plate 305d drives the sleeve 305a to move inward synchronously. Since the positioning block 305c is in the surrounding groove 304d, the deflection force of the surrounding groove 304d drives the toggle rod 304a to rotate.

[0042] The rest of the structure is the same as that of Example 1.

[0043] In summary, when the sinking assembly 200 needs to be installed, the position of the plug rod 302a on the inner side of the fixing frame 206 is first aligned with the fixing groove 301b, so that the plug rod 302a is pressed into the fixing groove 301b. Since the head of the block 303f is a wedge-shaped structure, when the plug rod 302a enters the fixing groove 301b, the block 303f is squeezed and retracts into the locking groove 303d. When the slot 302b moves to the position of the block 303f, the block 303f is correspondingly pressed into the slot 302b, completing the locking of the plug rod 302a and unlocking it. When the screw rod 305e is rotated, the connecting plate 305d drives the sleeve 305a to move inward synchronously. Since the positioning block 305c is in the surrounding groove 304d, the deflection force of the surrounding groove 304d drives the toggle rod 304a to rotate. When the toggle plate 304b on the toggle rod 304a rotates to a position corresponding to the arc block 303g, the arc block 303g is correspondingly pressed into the notch 304c. At this time, the spring piece 303b is released, so that the locking block 303c rotates clockwise, so that the card block 303f can be separated from the card slot 302b.

[0044] Example 3, reference Figures 1 to 9 , which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides an auxiliary component 306 of the waste oil continuous flocculation, sedimentation and slag discharge device. The auxiliary component 306 includes a movable plate 306a fixedly connected to the outer wall of the sleeve 305a. A torsion spring 306b is sleeved on the outer wall of the sleeve 305a. The torsion spring 306b is a carbon spring with high strength and is convenient for daily use. One end of the torsion spring 306b is fixedly connected to the outer wall of the movable plate 306a, and the other end of the torsion spring 306b is against the inner wall of the fixed groove 301b. One end of the movable plate 306a is fixedly connected to a limiting plate 306c, and the limiting plate 306c is in contact with the abutment block 302c.

[0045] Depend on Figures 6 to 8 It can be seen that Example 3 further limits the structure of Example 2, and a movable plate 306a is fixedly connected to the outer wall of the sleeve 305a, so that the movable plate 306a moves synchronously with the sleeve 305a. At the same time, a torsion spring 306b is sleeved on the outer side of the sleeve 305a, which is connected to the movable plate 306a and is used to limit the position of the screw sleeve, so that the screw sleeve will not be separated from the fixed block 301a due to a long movement stroke, and the movable plate 306a is fixedly connected to the limiting plate 306c in the 90° direction. The present device can realize the movement of the limiting plate 306c by controlling the movement of the sleeve 305a, so that the limiting plate 306c and the resistance plate are in contact, thereby realizing secondary locking of the device.

[0046] The rest of the structure is the same as that of Example 2.

[0047] In summary, it can be known from Example 2 that when the block 303f is correspondingly abutted against the slot 302b, the screw 305e is rotated at this time, so that the connecting plate 305d drives the sleeve 305a to move synchronously. Since the positioning block 305c is in the surrounding groove 304d, due to the deflection force of the surrounding groove 304d, the toggle rod 304a is driven to rotate clockwise. At this time, the limit plate 306c and the resistance plate are in contact, thereby realizing the secondary locking of the insertion rod 302a. When unlocking, it is only necessary to reverse the screw 305e to make the toggle rod 304a rotate counterclockwise. At this time, the limit plate 306c and the resistance plate are no longer in contact. If the reversal continues, the block 303f will be disengaged from the slot 302b, thereby realizing the overall unlocking of the device.

[0048] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
