Description

Technical Field

[0001] The utility model relates to a sedimentation tank, in particular to a sedimentation tank with a conical bottom of a guiding cylinder. Background Art

[0002] In the process of biological products such as plasma protein production, sewage treatment equipment is required to ensure that the discharged production wastewater will not pollute the environment. The use of sewage treatment equipment is an essential equipment for the production of biological products.

[0003] In the prior art, the sewage treatment equipment includes: an aeration tank, a sedimentation tank and a membrane tank. The first sewage treatment is carried out in the aeration tank. The muddy sewage is pumped into the bottom of the sedimentation tank by a water pump in the aeration tank. The separation of water and sediment in the muddy sewage is realized in the sedimentation tank. The second sewage treatment is carried out in the sedimentation tank, and then the clear water flows out from the top of the sedimentation tank. The clear water enters the membrane tank for the third sewage treatment.

[0004] In the above process, although the biological production sewage can reach the discharge standard after treatment, the sewage treatment equipment still has the following disadvantages: Although the water pump directly pumps the muddy sewage into the bottom of the sedimentation tank through a water pipe, when the muddy sewage enters the bottom of the sedimentation tank, the muddy sewage impacts the sediment at the bottom of the sedimentation tank, causing the sediment to directly move towards the drain pipe direction, resulting in more sediment entering the membrane tank, blocking the membrane module in the membrane tank, reducing the water output, increasing the frequency of cleaning the membrane module in the membrane tank, damaging the membrane module, and reducing the service life. Content of the Utility Model

[0005] The utility model aims to provide a sedimentation tank with a conical bottom of a guiding cylinder to solve the problem that the sediment directly moves towards the drain pipe at the top of the sedimentation tank after the muddy sewage impacts the sediment at the bottom of the sedimentation tank in the prior art.

[0006] To achieve the above object, the utility model adopts the following technical scheme:

[0007] The utility model discloses a sedimentation tank with a conical bottom of a guiding cylinder, which comprises: a tank body, a mounting frame, a water inlet pipe, a water spray head, a water supply cylinder, a blocking guiding cylinder, a sludge discharge pipe, a drain pipe and a water inlet driving pump. The mounting frame is installed on the top of the tank body, and the water inlet driving pump is installed on the mounting frame. The water inlet pipe penetrates into the water supply cylinder from one side of the top of the tank body, and the end of the water inlet pipe located in the water supply cylinder is communicated with the water spray head. The water spray head sprays water towards the top end of the water supply cylinder. The water inlet driving pump is used to drive the water flow in the water inlet pipe. The bottom of the water supply cylinder extends to the bottom of the tank body. The sludge discharge pipe extends into the bottom of the tank body. The input end of the drain pipe is communicated with the top of the tank body. A blocking guiding cylinder is installed in the middle of the water supply cylinder. The blocking guiding cylinder surrounds the outside of the water supply cylinder. The bottom of the blocking guiding cylinder is a conical blocking section, and the small end of the blocking section is located above the large end of the blocking section.

[0008] Preferably, the water supply cylinder includes: an upper cylinder body, a lower cylinder body, an external thread ring, and an internal thread ring. The top of the upper cylinder body is closed. An external thread ring extends downward from the bottom of the upper cylinder body. The external thread ring is threadedly connected with the internal thread ring. The internal thread ring is fixed to the top of the lower cylinder body. The bottom of the lower cylinder body extends into the bottom of the pool body.

[0009] Preferably, a recessed insertion groove is formed on the bottom surface of the external thread ring, and the internal thread ring presses the water inlet pipe against the inner wall of the top of the insertion groove.

[0010] Preferably, a step is formed at the connection between the upper cylinder body and the external thread ring. A first clamping sealing ring is installed on the step. A pushing ring is sleeved outside the external thread ring. The pushing ring is located below the water inlet pipe. A second clamping sealing ring is installed on the pushing ring. The internal thread ring is located below the pushing ring. The internal thread ring presses the second clamping sealing ring against the water inlet pipe through the pushing ring.

[0011] Preferably, the top of the blocking and guiding cylinder surrounds the external thread ring, and the top of the blocking and guiding cylinder is pressed by the internal thread ring against the pushing ring.

[0012] Preferably, the blocking and guiding cylinder includes: an installation section and an intermediate section. The installation section surrounds the external thread ring. The installation section is clamped by the internal thread ring and the pushing ring. The bottom end of the installation section is fixed to one end of the intermediate section. The other end of the intermediate section is fixed to the small end of the blocking section.

[0013] Preferably, a circular baffle is provided at the top of the pool body. An annular groove is formed between the circular baffle and the inner wall of the pool body. The input end of the drain pipe extends into the annular groove. The circular baffle is installed on the top of the pool body through at least three installation feet.

[0014] Preferably, a support platform is formed on the inner wall of the top of the pool body, and the support platform supports the installation feet.

[0015] Preferably, a recessed suspension groove is formed on the surface of an installation foot that is in close contact with the inner wall of the pool body. An ear is suspended in the suspension groove. The ear is fixed to the top of a filter tank body. Water inlet holes are provided at the bottom of the filter tank body. The filter tank body is communicated with the input end of the drain pipe.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] In the present application, the water inlet drive pump causes the water inlet pipe to spray water toward the top of the water supply cylinder. Since the impact force of the water sprayed out from the water inlet pipe is large, it directly rushes to the top of the water supply cylinder. After the water encounters the inner wall of the top of the water supply cylinder, it is guided along the inner wall of the water supply cylinder to the bottom of the pool body. After the water falls to the bottom of the pool body, the sediment will rise. Therefore, a blocking guide cylinder is used. The blocking guide cylinder surrounds the outside of the water supply cylinder, and a blocking section with a conical structure is formed at the bottom of the blocking guide cylinder. Since the area of the sediment floating up is large when the water falls to the bottom of the pool body, the blocking section with a conical structure is used to block the sediment from rising, thereby reducing the possibility of the sediment entering the drain pipe, avoiding subsequent large amounts of sediment from entering the membrane pool through the drain pipe to block the membrane assembly, and extending the service life of the membrane assembly.

[0018] Other advantages, objectives and features of the present invention will be embodied in part through the following description, and in part will be understood by those skilled in the art through research and practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and functions of the present invention clearer and easier to understand, the present invention is further described below in conjunction with the accompanying drawings and specific implementation methods:

[0025] like Figures 1 to 4As shown in the figure, the utility model discloses a conical sedimentation tank at the bottom of a guide cylinder, which includes: a tank body 1, a mounting frame 2, a water inlet pipe 3, a water spray head 4, a water supply cylinder 5, a blocking guide cylinder 6, a sludge discharge pipe (not shown in the figure), a drain pipe 7 and a water inlet driving pump (not shown in the figure). A mounting frame 2 is installed at the top of the tank body 1, and a water inlet driving pump is installed on the mounting frame 2. The water inlet pipe 3 penetrates into the water supply cylinder 5 from one side of the top of the tank body 1, and a water spray head 4 is connected to the end of the water inlet pipe 3 located in the water supply cylinder 5. The water spray head 4 sprays water towards the top of the water supply cylinder 5. The water inlet driving pump is used to drive the water flow in the water inlet pipe 3. The bottom of the water supply cylinder 5 extends to the bottom of the tank body 1, the sludge discharge pipe extends into the bottom of the tank body 1, and the input end of the drain pipe 7 is connected to the top of the tank body 1; A blocking guide cylinder 6 is installed in the middle of the water supply cylinder 5. The blocking guide cylinder 6 surrounds the outside of the water supply cylinder 5. The bottom of the blocking guide cylinder 6 is a conical blocking section 63, and the small end of the blocking section 63 is located above the large end of the blocking section 63.

[0026] The water supply cylinder 5 includes: an upper cylinder body 51, a lower cylinder body 52, an external thread ring 53 and an internal thread ring 54. The top of the upper cylinder body 51 is closed, the bottom end of the upper cylinder body 51 extends downward with an external thread ring 53, and an internal thread ring 54 is threadedly connected to the external thread ring 53. The internal thread ring 54 is fixed to the top end of the lower cylinder body 52, and the bottom end of the lower cylinder body 52 extends into the bottom of the tank body 1. The water supply cylinder 5 is divided into a cylinder body, a lower cylinder body 52, an external thread ring 53 and an internal thread ring 54 for the purpose of clamping the water inlet pipe 3 between the upper cylinder body 51 and the lower cylinder body 52.

[0027] A insertion groove is formed by the depression of the bottom surface of the external thread ring 53, and the internal thread ring 54 presses the water inlet pipe 3 against the inner wall of the top of the insertion groove. Since the end of the water inlet pipe 3 located in the water supply cylinder 5 bends upward and is connected with a water spray head 4, the water inlet pipe 3 cannot be directly inserted into the water supply cylinder 5. The insertion groove is designed so that the water inlet pipe 3 can be clamped into the insertion groove, and then when the lower cylinder body 52 and the internal thread ring 54 are installed, the insertion groove can be closed to realize clamping of the water inlet pipe 3.

[0028] A step is formed at the connection between the upper cylinder body 51 and the external thread ring 53. A first clamping sealing ring 55 is installed on the step. A pushing ring 56 is sleeved outside the external thread ring 53. The pushing ring 56 is located below the water inlet pipe 3. A second clamping sealing ring 57 is installed on the pushing ring 56. The internal thread ring 54 is located below the pushing ring 56, and the internal thread ring 54 presses the second clamping sealing ring 57 against the water inlet pipe 3 through the pushing ring 56. The first clamping sealing ring 55 and the second clamping sealing ring 57 clamp the water inlet pipe 3. Both the pushing ring 56 and the second clamping sealing ring 57 are provided with notches corresponding to the water inlet pipe 3, and the notches are for the water inlet pipe 3 to be placed into.

[0029] The top of the blocking guide cylinder 6 surrounds the external thread ring 53, and the top of the blocking guide cylinder 6 is pressed against the pushing ring 56 by the internal thread ring 54. The installation of the blocking guide cylinder 6 is realized.

[0030] The blocking and guiding cylinder 6 includes: a mounting section 61 and an intermediate section 62. The mounting section 61 surrounds the external thread ring 53 and is clamped by the internal thread ring 54 and the pushing ring 56. The bottom end of the mounting section 61 is fixed to one end of the intermediate section 62, and the other end of the intermediate section 62 is fixed to the small end of the blocking section 63. The blocking section 63, the mounting section 61, and the intermediate section 62 all belong to the blocking and guiding cylinder 6. The setting of the intermediate section 62 makes the whole blocking and guiding cylinder 6 longer, so that there is also an upward movement space after the sediment impact, reducing the possibility of the sediment approaching the output end of the drain pipe 7.

[0031] A circular baffle 8 is provided at the top of the pool body 1. An annular groove is formed between the circular baffle 8 and the inner wall of the pool body 1. The input end of the drain pipe 7 extends into the annular groove. The circular baffle 8 is installed on the top of the pool body 1 through at least three mounting feet 80. The circular baffle 8 and the pool body 1 form an annular groove for the output end of the drain pipe 7 to extend into, having the effect of blocking floating objects.

[0032] A support platform is formed on the inner wall of the top of the pool body 1 to support the mounting feet 80. The circular baffle 8 is installed through the cooperation of the mounting feet 80 and the support platform.

[0033] A recessed hanging groove is formed on the surface of a mounting foot 80 in contact with the inner wall of the pool body 1. An ear is hung in the hanging groove and fixed to the top of a filter tank body 9. Water inlet holes are provided at the bottom of the filter tank body 9, and the filter tank body 9 is communicated with the input end of the drain pipe 7. The filter tank body 9 is also installed through the mounting feet 80, ensuring that the mounting feet 80 have both the function of supporting the filter tank body 9 and the function of supporting the circular baffle 8. The output end of the drain pipe 7 extends into the filter tank body 9, and then it also has the function of preventing sediment and other impurities from entering the drain pipe 7.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
