Description

Technical Field

[0001] The utility model relates to the technical field of fine sand sewage separation, in particular to a sewage separation device for fine sand recovery. Background Art

[0002] Fluid cyclone is an important equipment for separating two-phase or multi-phase mixtures such as liquid-liquid, liquid-solid, liquid-gas, etc. with a certain density difference. When the two-phase mixed liquid to be separated enters the cyclone tangentially from the periphery of the cyclone at a certain pressure, a strong three-dimensional elliptical strong rotation shear turbulent motion is generated. Due to the difference in particle size between coarse particles and fine particles, they are subjected to different centrifugal forces, centripetal buoyancy, fluid drag, etc., and are subjected to centrifugal sedimentation. Most of the coarse particles are discharged through the bottom flow port of the cyclone, while most of the fine particles are discharged from the overflow pipe, thereby achieving the purpose of separation and classification.

[0003] Patent document with publication number CN220238909U discloses a hydraulic cyclone for reducing impact force. The cylinder is fixed in a suitable position, and mortar is introduced into the cylinder through a feed pipe at a certain pressure. The mortar is blocked by a baffle, which can reduce its flow range. At the same time, the spring is compressed, which can reduce the impact force of the mortar on the cylinder. The mortar flows in the space formed by the outer side of the guide plate and the cylinder, and can quickly form a vortex flow toward the lower end of the cylinder.

[0004] During the flow of external vortex flow, the mortar is in direct contact with the protective tube. The impact force of the mortar on the protective tube is absorbed by the buffer pad, thereby reducing the impact on the tube body. The protective tube can also prevent the mortar from directly wearing the tube body. When the protective tube is severely worn, it is only necessary to remove the bolts and replace the protective tube without replacing the entire tube body, thus saving costs.

[0005] After the inner vortex flows upward and enters the overflow pipe, the impact force is also reduced under the action of the baffle and the spring, thereby reducing the impact on the bending part of the overflow pipe, which is beneficial to increasing the service life of the overflow pipe.

[0006] However, in the process of implementing the above technical solution, it is found that the above technical solution has the following technical problems:

[0007] The existing hydrocyclone for reducing impact force has a protective tube arranged inside the cylinder, and the mortar exerts impact on the inner wall of the protective tube to protect the entire cylinder. However, the protective tube is fixed and a buffer pad is arranged between the protective tube and the cylinder. In actual application, the protective tube can only replace the cylinder to be worn, and it is difficult to reduce the degree of wear and tear to extend the maintenance period of the cyclone. Utility Model Content

[0008] In order to overcome the existing hydrocyclone that reduces impact force, the protective cylinder is fixed, and a buffer pad is arranged between the protective cylinder and the cylinder body to protect the cylinder body. In actual application, the protective cylinder can only replace the cylinder body to be worn, and it is difficult to reduce the degree of wear and tear to extend the maintenance period of the cyclone. The embodiment of the present application provides a sewage separation device for fine sand recovery. By setting the protective inner liner to be used in combination with a first inner liner, a second inner liner and a third inner liner, a plurality of support rings composed of steel balls are correspondingly arranged between the first inner liner and the upper vertebral body, the second inner liner and the middle vertebral body, and the third inner liner and the lower vertebral body. When the material enters the interior of the vortex body through the feed pipe, a vortex is generated and moves to the bottom, the friction force drives the protective inner liner to rotate inside the cyclone. In the process of fine sand settling and sewage overflowing from the top of the overflow pipe, the medium can be prevented from wearing the inner wall of the protective inner liner, so as to extend the maintenance period of the cyclone and increase the service life.

[0009] The technical solution adopted by the embodiment of the present application to solve the technical problem is:

The multiple positioning rods on the first inner liner are inserted into the top of the second inner liner, and the multiple positioning rods on the second inner liner are inserted into the top of the third inner liner.

[0015] In one possible implementation, the top outer walls of the first inner liner, the second inner liner and the third inner liner are all processed with limiting rings, the support ring located at the top inner wall of the upper vertebral body is supported on the bottom surface of the limiting ring on the first inner liner, the support ring located at the top inner wall of the middle vertebral body is supported on the bottom surface of the limiting ring on the second inner liner, and the support ring located at the top inner wall of the lower vertebral body is supported on the bottom surface of the limiting ring on the third inner liner.

DETAILED DESCRIPTION

[0026] The technical solution in the embodiment of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

[0027] Embodiment 1:

[0028] This embodiment introduces a specific structure of a wastewater separation device for fine sand recovery. Figure 1-Figure 6 As shown, it includes a cyclone tube 4 and a protective liner 6 arranged on the inner side of the cyclone tube 4, the protective liner 6, the cyclone tube 4 includes an upper cone 401, the bottom of the upper cone 401 is assembled and connected with a middle cone 402, the bottom of the middle cone 402 is assembled and connected with a lower cone 403, the bottom of the lower cone 403 is assembled and connected with a straight cylinder 404, the top of the upper cone 401 is assembled and connected with a vortex body 2, the outer wall of the top of the vortex body 2 is integrally formed with a feed pipe 3, the top of the vortex body 2 is assembled and connected with an overflow pipe 1, the bottom of the straight cylinder 404 is assembled and connected with a splash shield 5, and a support ring 7 is arranged between the outer wall of the protective liner 6 and the inner wall of the cyclone tube 4;

[0029] The support ring 7 is composed of a plurality of steel balls. By supporting the plurality of steel balls between the inner wall of the cyclone tube 4 and the outer wall of the protective liner 6, the protective liner 6 can be supported to be rotatably connected to the inside of the cyclone tube 4. When the material enters the inside of the vortex body 2 through the feed pipe 3, generates a cyclone and moves to the bottom, the friction force drives the protective liner 6 to rotate inside the cyclone tube 4. In the process of fine sand settling and sewage overflowing from the top of the overflow pipe 1, the medium can be prevented from wearing the inner wall of the protective liner 6, and the inertia of the protective liner 6 during rotation can be used to assist the separation of sewage and fine sand.

[0030] Secondly, in order to facilitate the installation of the support ring 7 composed of multiple steel balls to the inner side of the cyclone tube 4, as shown in FIG. Figure 5 As shown, the top inner wall and the bottom inner wall of the upper vertebral body 401, the middle vertebral body 402 and the lower vertebral body 403 are processed with a receiving ring groove 9, and the support ring 7 is received inside the limiting ring 8 to prevent the support ring 7 from sliding up and down between the outer wall of the protective liner 6 and the inner wall of the cyclone tube 4;

[0031] At the same time, the processing depth of the receiving ring groove 9 at the inner wall of the upper vertebral body 401, the middle vertebral body 402 and the lower vertebral body 403 is controlled to ensure that the depth of each receiving ring groove 9 is the same. During the installation of the support ring 7, the support ring 7 can be stably supported on the outer wall of the protective liner 6 to prevent the protective liner 6 from shaking inside the cyclone 4;

[0032] Furthermore, in order to prevent the support ring 7 from being separated from the inside of the receiving ring groove 9 after being installed therein, which would cause inconvenience to the installation of the protective liner 6, the receiving ring groove 9 is oriented in a manner perpendicular to the outer wall of the protective liner 6 and the inner wall of the cyclone tube 4, so that the support ring 7 is tilted toward the top as a whole. In the process of installing the support ring 7, the support ring 7 can be prevented from falling from the inside of the receiving ring groove 9.

[0033] like Figure 2 As shown, the protective liner 6 includes a first liner 601, a second liner 602 and a third liner 603, and the bottom ends of the first liner 601 and the second liner 602 are processed with a plurality of positioning rods 10;

[0034] The first inner liner 601 is adapted to be connected to the interior of the upper vertebral body 401, the second inner liner 602 is adapted to be connected to the interior of the middle vertebral body 402, and the third inner liner 603 is adapted to be connected to the interior of the lower vertebral body 403;

[0035] Secondly, by making multiple positioning rods 10 equally spaced around the axis of the protective inner liner 6, when multiple positioning rods 10 on the first inner liner 601 are plugged into the top of the second inner liner 602, and multiple positioning rods 10 on the second inner liner 602 are plugged into the top of the third inner liner 603, the first inner liner 601, the second inner liner 602 or the third inner liner 603 can be independently rotated to align the positioning rods 10 with the installation position, and finally the installation work is completed;

[0036] In some examples, the top outer walls of the first inner liner 601 , the second inner liner 602 , and the third inner liner 603 are all processed with a limiting ring 8 ;

[0037] Among them, by making the support ring 7 located at the top inner wall of the upper vertebral body 401 supported on the bottom surface of the limiting ring 8 on the first inner liner 601, the support ring 7 located at the top inner wall of the middle vertebral body 402 supported on the bottom surface of the limiting ring 8 on the second inner liner 602, and the support ring 7 located at the top inner wall of the lower vertebral body 403 supported on the bottom surface of the limiting ring 8 on the third inner liner 603, the protective inner liner 6 can be suspended as a whole inside the cyclone tube 4.

[0038] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
