Description

Technical Field

[0001] The utility model relates to the technical field of anaerobic bioreactors, and particularly relates to a swirl water distribution device. Background Art

[0002] A hydrocyclone is a device that converts the linear motion of a liquid into a rotating centrifugal force motion field under the action of pressure and uses the density difference of different components for multiphase separation. The intensity of the centrifugal force field is much larger than that of the gravity field (tens to thousands of times), so the separation efficiency of the hydrocyclone is much higher than that of gravity separation. The hydrocyclone has many advantages such as simple structure, convenient operation, large processing capacity, and easy realization of large-scale and automation, making its application in various fields more and more extensive. The structure of the swirl water distributor mainly consists of an inlet, a cylinder body, an overflow, and an underflow. The existing swirl water distribution structure lacks path constraints on the swirl, resulting in the outlet direction being greatly affected by the overflow angle of the swirl itself, and it is not easy to adjust the overflow outlet angle of the swirl. For this reason, we propose a swirl water distribution device that is convenient for controlling the outlet angle of the swirl. Content of the Utility Model

[0003] The purpose of the utility model is to provide a swirl water distribution device to solve the problems raised in the above background art.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A swirl water distribution device includes a cylinder body, which serves as a flow-through channel for the water body to be distributed, so that the water body flowing through the cylinder body forms a swirl when flowing out of the underflow part, providing a water distribution swirl for the anaerobic bioreactor. A conical spiral drainage structure is arranged on the inner wall of the cylinder body, and the conical spiral drainage structure can make the water body form a swirl when flowing through the cylinder body. A depression is formed on the inner wall of the conical spiral drainage structure, and the depression can limit the water body to be distributed, making the flowing water body converge in a stream. One end of the conical spiral drainage structure is tangentially connected to a connection section, and one end of the connection section is communicated with a connecting pipe. The connection section serves as a connection structure connecting the conical spiral drainage structure and the connecting pipe, and can make the water body flow into the conical spiral drainage structure from the connecting pipe. A flow meter and a flow regulating valve are penetrated and connected to the surface of the connecting pipe. The flow meter can detect the flow velocity of the water body in the connecting pipe. Through the transparent plate on the top cover, the flow path of the water flow in the cylinder body can be observed. When the flow path of the water body is too wide or too narrow, the flow rate of the water body per unit time can be adjusted through the flow regulating valve, so that the flow velocity of the water flowing out of the cylinder body meets the preset expectation.

[0005] As a further scheme of the utility model: The cylinder body is a hollow inverted frustum cylinder, and the bottom of the cylinder body is integrally formed with an underflow part. The underflow part is a hollow pipe with both ends open and expanding outwards. The height of the cylinder body is greater than the height of the conical spiral drainage structure, which can avoid the cylinder body affecting the flow path of the water flow.

[0006] As a further solution of the present utility model: The conical spiral drainage structure is a conical spiral strip welded to the inner wall of the cylinder, and the conical spiral strip can drain the swirling water body.

[0007] As a further solution of the present utility model: The cross-section of the conical spiral drainage structure is a long strip-shaped quadrilateral with thick ends and thin middle, which can form a depression, facilitating the rectification of the water body and avoiding the dispersion of the water body during the flowing process.

[0008] As a further solution of the present utility model: The conical spiral drainage structure is a conical spiral groove opened on the inner wall of the cylinder. The conical spiral drainage structure can rectify the water body, and the cylinder can serve as a positioning and connecting structure for the conical spiral drainage structure.

[0009] As a further solution of the present utility model: A threaded connection ring is integrally formed at the top of the cylinder. The threaded connection ring is a hollow thin-walled cylindrical pipe. The surface of the threaded connection ring is threadedly connected with a top cover. A transparent plate is fixedly penetrated through the top of the top cover. The transparent plate is convenient for observing the water flow path in the cylinder and timely adjusting the water flow rate.

[0010] As a further solution of the present utility model: The connection section is an arc-shaped plate with a depression on one side, which can drain the water flow.

[0011] As a further solution of the present utility model: The connection section is a cylindrical pipe tangent to the conical spiral drainage structure, which can avoid the dispersion of the water flow during the process of draining the water body.

[0012] As a further solution of the present utility model: A hexagonal joint is welded to one end of the connecting pipe. A spiral groove is opened on the inner wall of the hexagonal joint. The connecting pipe penetrates through the cylinder. The connecting pipe is a rigid pipe. The hexagonal joint can be connected to an external water body conveying channel.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] 1. By setting the cylinder in the shape of an inverted frustum and the conical spiral drainage structure, the present utility model can limit and drain the water flow flowing in the cylinder, keep the width of the water flow for water distribution the same, and at the same time, the conical spiral drainage structure can keep the angle when the water flow for water distribution flows out of the bottom flow part.

[0015] 2. By setting the expanded bottom flow part, the present utility model can avoid the influence of the too small diameter of the bottom flow part on the swirling outflow speed and direction. By setting the cross-section of the conical spiral drainage structure as a long strip-shaped quadrilateral with thick ends and thin middle and forming a depression, it is beneficial to rectify the water body and avoid the dispersion of the water body during the flowing process. By installing a transparent plate on the top of the top cover, the transparent plate is convenient for observing the water flow path in the cylinder and timely adjusting the water flow rate.

[0022] Please refer to Figures 1-4 , the present utility model provides a technical solution: a swirl water distribution device, including a cylinder body 1. The cylinder body 1 serves as the flowing channel of the water body for water distribution. The water body flowing through the cylinder body 1 forms a swirl when flowing out of the underflow part 2, providing a swirling water distribution for the anaerobic bioreactor. A threaded connection ring 12 is integrally formed at the top of the cylinder body 1. The threaded connection ring 12 is a hollow thin-walled cylindrical pipe. The surface of the threaded connection ring 12 is threadedly connected with a top cover 3. A transparent plate 4 is fixedly penetrated through the top of the top cover 3. The transparent plate 4 is convenient for observing the water flow path in the cylinder body 1 and for timely adjusting the flow rate of the water body.

[0023] The inner wall of the cylinder 1 is provided with a conical spiral drainage structure 5, which can form a vortex when the water flows through the cylinder 1. A depression 6 is formed on the inner wall of the conical spiral drainage structure 5, which can limit the water distribution and make the flowing water converge into strands. One end of the conical spiral drainage structure 5 is tangentially connected with a connecting section 7, and one end of the connecting section 7 is connected with a connecting pipe 8. The connecting section 7 serves as a connecting structure connecting the conical spiral drainage structure 5 and the connecting pipe 8, so that the water can flow from the connecting pipe 8 into the conical spiral drainage structure 5. The surface of the connecting pipe 8 is penetrated by a flow meter 10 and a flow regulating valve 11. The flow meter 10 can detect the flow rate of the water in the connecting pipe 8. The flow path of the water flow in the cylinder 1 can be observed through the transparent plate 4 on the top of the top cover 3. When the water flow path is too wide or too narrow, the flow rate of the water per unit time can be adjusted by the flow regulating valve 11, so that the flow rate of the water flowing out of the cylinder 1 meets the preset expectations.

[0024] Preferably, Figure 1 As shown, the cylinder 1 is a hollow inverted frustum cylinder, and a bottom flow portion 2 is integrally formed at the bottom of the cylinder 1. The bottom flow portion 2 is a hollow pipe with openings at both ends and extending outward. The height of the cylinder 1 is greater than the height of the conical spiral drainage structure 5, which can prevent the cylinder 1 from affecting the flow path of the water.

[0025] Preferably, Figure 2 As shown, the conical spiral drainage structure 5 is a conical spiral strip welded to the inner wall of the cylinder 1, and the conical spiral strip can drain the swirling water.

[0026] Preferably, Figure 4 As shown, the cross section of the conical spiral drainage structure 5 is a long strip-shaped quadrilateral with thick ends and a thin middle, which can form a depression 6, which is beneficial to rectifying the water body and avoiding dispersion during the flow of the water body.

[0027] Preferably, Figure 4 As shown, the connecting section 7 is an arc-shaped plate with a recess 6 on one side, which can guide the water flow.

[0028] Preferably, Figure 3 As shown, the connecting section 7 is a cylindrical tube tangent to the conical spiral drainage structure 5, which can prevent water flow dispersion during the process of draining the water body.

[0029] Preferably, Figure 3 As shown, a hexagonal joint 9 is welded at one end of the connecting pipe 8, a spiral groove is provided on the inner wall of the hexagonal joint 9, the connecting pipe 8 passes through the cylinder 1, the connecting pipe 8 is a hard pipe, and the hexagonal joint 9 can be connected to an external water delivery channel.

[0030] Working principle: When in use, connect the hexagonal joint 9 to the external water body conveying channel, convey the water body for water distribution through the hexagonal joint 9 into the connecting pipe 8, and the connecting pipe 8 conveys the water body through the connection section 7 to the conical spiral drainage structure 5. By tangentially connecting the connection section 7 with the conical spiral drainage structure 5, it can reduce the kinetic energy loss of the water body when the water body flows from the connection section 7 into the conical spiral drainage structure 5. Through the flow of the water body in the depression 6 of the conical spiral drainage structure 5, the depression 6 can rectify the water body, avoid the dispersion of the water body, and is beneficial to maintaining the flow path of the water body, so that the water body meets the desired swirling flow velocity and direction when flowing out from the bottom flow part 2. By setting the expanded bottom flow part 2, it can avoid the influence of the too small diameter of the bottom flow part 2 on the swirling flow out velocity and direction.
