Description

Technical Field

[0001] This utility model belongs to the technical field of sludge treatment equipment, specifically relating to a cyclone-type oily sludge treatment and separation cylinder. Background Technology

[0002] In recent years, cyclone separation technology has gradually emerged in the field of oily sludge treatment due to its high efficiency and energy saving. This technology mainly uses high-speed rotating airflow to form a strong centrifugal force field, so that different components in the sludge (such as oil, water, and solid particles) can be effectively separated due to differences in density and particle size. For example, the existing patent with publication number CN116217021B discloses "a cyclone oily sludge treatment device, including a separation cylinder, a cover plate with a feed inlet on the end face of the separation cylinder; a rotating jet mechanism, a vibrating screening mechanism and a cyclone separation mechanism are arranged in the inner cavity of the separation cylinder from top to bottom". It can be seen that the application describes a common cyclone oily sludge treatment device, and the cyclone separation mechanism is a cyclone oily sludge treatment separation cylinder.

[0003] However, in practical applications, cyclone separators also face some challenges, especially when dealing with untreated oily sludge. The sludge often contains large stones, wood blocks or other hard foreign objects. Once these foreign objects enter the separator, they may not only severely wear or damage the internal rotating parts and static sealing structure, but may also cause airflow turbulence, affecting the overall separation effect. Therefore, this utility model proposes a cyclone oily sludge treatment separator. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Please see Figures 1 to 4 This is the first embodiment of the present invention, which provides a technical solution: a cyclone-type oily sludge treatment and separation cylinder, comprising...

[0024] The cyclone separator 1 includes an inlet 2 on its top surface, a high-pressure air inlet pipe 5 on one side, an overflow outlet 3 and a sediment outlet 4 on the other side. The inner wall of the cyclone separator 1 is equipped with multiple guide vanes 11. One side of the cyclone separator 1 has a pressure-bearing chamber 51 communicating with the high-pressure air inlet pipe 5, and the inner wall of the cyclone separator 1 is fitted with multiple injection pipes 52 communicating with the pressure-bearing chamber 51. After the high-pressure air inlet pipe 5 is connected to the external air source, the high-pressure airflow can be sprayed into the cyclone separator 1 through the jet pipe 52, so that the oily sludge entering the cyclone separator 1 is centrifugally separated. The separated sludge is discharged from the sludge outlet 4 under the guidance of the guide plate 11, while the oil overflows through the overflow outlet 3. The above structural principles are all technologies that have been fully disclosed in the prior art. For details, please refer to the existing patent with publication number CN116217021B. It will not be elaborated here.

[0025] A coarse filter assembly is installed inside the feed inlet 2. The coarse filter assembly includes a rectangular insert frame 61, railings 62, and an end plate 63. The rectangular insert frame 61 is welded and fixed to the railings 62, and multiple railings 62 are welded to the inner side of the rectangular insert frame 61. Oily sludge can pass through between two adjacent railings 62, while large stones or foreign objects will be blocked. A rectangular slot 21 is opened on one side surface of the feed inlet 2 for the rectangular insert frame 61 to be inserted. The rectangular insert frame 61 is inserted from one side of the feed inlet 2 to the inner side of the feed inlet 2, and the end plate 63 is attached to the side of the feed inlet 2. This allows the oily sludge to be filtered out by the multiple railings 62 after entering the feed inlet 2, preventing these large stones or foreign objects from entering the cyclone separator 1 and causing unnecessary damage. A limit structure 7 is also provided between the end plate 63 and the cyclone separator 1 for stable limiting during daily use.

[0026] In this embodiment, preferably, the limiting structure 7 includes a limiting strip 71 rotatably mounted on the surface of the end plate 63, and the top surface of the cyclone separator 1 is provided with a strip groove 72 corresponding to the limiting strip 71. The bottom end of the limiting strip 71 is screwed into the strip groove 72 to block and limit the end plate 63. If the end plate 63 and the rectangular insert 61 need to be removed laterally, the limiting strip 71 only needs to be rotated so that the bottom end of the limiting strip 71 is screwed out from the strip groove 72, and the end plate 63 can be moved laterally to remove the rectangular insert 61.

[0027] In this embodiment, preferably, a T-shaped shaft is fixed to the surface of the end plate 63, and the top end of the limiting strip 71 is rotatably sleeved on the shaft, so that the limiting strip 71 can rotate smoothly.

[0028] In this embodiment, preferably, the limiting structure 7 further includes an inner groove 73 formed inside the end plate 63, a spring 74 installed in the inner groove 73, and a telescopic locking bead 75. Two positioning slots 76 corresponding to the telescopic locking bead 75 are symmetrically formed on the side of the limiting strip 71. The telescopic locking bead 75 is movably installed in the inner groove 73 by the spring 74, and the end of the telescopic locking bead 75 pops out into one of the positioning slots 76. This allows the limiting strip 71 to be limited during daily use, preventing the limiting strip 71 from being stopped. The rectangular insert 61 can be unscrewed from the strip groove 72. If the rectangular insert 61 needs to be pulled out for cleaning and maintenance later, simply remove any large stones or foreign objects that have fallen from the top of the rectangular insert 61 and the railing 62. Then, push the limiting strip 71 forcefully so that the end of the telescopic ball 75 is squeezed into the inner groove 73, allowing the bottom of the limiting strip 71 to be smoothly unscrewed from the strip groove 72. This allows the end plate 63 to be moved to the side, and the rectangular insert 61 and the railing 62 to be easily pulled out for cleaning and maintenance.

[0029] In this embodiment, preferably, one end of the spring 74 is fixed to the inner wall of the inner groove 73, and the other end of the spring 74 is fixed to the telescopic retaining bead 75.

[0030] Example 2

[0031] Please see Figures 1 to 4 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that a strip rubber seat 22 is embedded in the inner walls of both sides of the rectangular socket 21, and the surface of the strip rubber seat 22 is provided with two integrated strip sealing protrusions 23. Both are made of rubber material and will undergo elastic deformation when squeezed. The strip sealing protrusions 23 are squeezed and contacted with the rectangular socket 61 to form a double sealing structure to prevent sludge from seeping out from the rectangular socket 21.

[0032] In this embodiment, preferably, the strip rubber seat 22 is a hollow structure, so that the strip sealing protrusion 23 has sufficient deformation space when it is squeezed.

[0033] In this embodiment, preferably, a rectangular groove is provided on the inner walls of both sides of the rectangular socket 21, and the strip rubber seat 22 is installed in the groove, so that the strip rubber seat 22 can be installed in an embedded manner, so that the strip rubber seat 22 itself does not affect the normal insertion and removal of the rectangular socket 61.

[0034] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
