Description

TECHNICAL FIELD

[0001] The utility model relates to a sewage treatment technical field, concretely relates to a sewage pump drainage drainage tube. BACKGROUND

[0002] Most centrifugal sewage pumps use packing seals, which allow a certain amount of leakage. On the other hand, due to the long service life of the equipment, the shaft sleeve and the packing chamber are poorly matched, resulting in poor sealing and leakage of sewage along the packing. The leaked sewage flows out of the pump drain, making the pump seat and the equipment foundation all sewage, which can easily cause the pump seat to rust, posing a hidden danger to the operation of the equipment and also posing a serious hidden danger to environmental protection.

[0003] The patent document with publication number CN205605415U discloses a reciprocating pump plunger packing leakage liquid closed recovery device. When in use, the leakage liquid collected at the reciprocating pump plunger packing is introduced into the booster pump through the recovery pipeline under the condition that the inlet gate valve is open. After being pressurized by the booster pump, the leakage liquid is introduced into the output pipeline connected with the pump body through the open outlet gate valve and the outlet check valve. The impurities contained in the collected leakage liquid can be effectively filtered through the filter screen, avoiding blockage of the recovery pipeline, the booster pump, and other gate valves. However, the device needs to be provided with a booster pump to introduce the leaked sewage into the output pipeline connected with the pump body, thus increasing the equipment investment cost and the use cost.

[0004] The patent document with publication number CN209027732U discloses a centrifugal pump packing seal leakage collection alarm device. The device includes a sealing box in a barrel shape. A magnet ring is provided on the circular ring plane of one side of the barrel-shaped sealing box. An O-ring groove is also provided on the circular ring plane, and an O-ring is arranged in the groove. An inner hole is provided on the other side of the sealing box, and a sealing ring groove is provided on the ring wall of the inner hole. A sealing ring is arranged in the groove. A hole is provided at the lower part of the sealing box to connect a collection chamber, which is a closed container. An electrode is installed at the top of the collection chamber. The electrode installation hole is sealingly connected with the collection chamber. Two electrode pins of the electrode extend into the middle part of the collection chamber. A sewage discharge valve is provided at the bottom of the collection chamber. The device can collect the liquid leaked from the packing and has an active alarm function, avoiding the environmental pollution caused by the leakage of the packing. However, the device needs to automatically discharge the sewage at regular intervals, which is troublesome to use. UTILITY MODEL CONTENTS

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1: Refer to Figures 1-3 As shown, a sewage pump discharge pipe includes a tee 1, and a plug 3 is detachably and fixedly sealed at the first side end of the tee 1.

[0024] The second end of the tee 1 is connected to a conduit 15. The conduit 15 is detachably and fixedly sealed to the second end of the tee 1.

[0025] The upper end of the tee 1 is fixedly sealed with a connecting pipe 6. A retaining ring 9 is fixed at the upper end of the connecting pipe 6. A sealing ring 10 is fitted on the connecting pipe 6 below the retaining ring 9. A top sleeve 11 is fitted on the connecting pipe 6 below the sealing ring 10.

[0026] A threaded sleeve 7 is threadedly sealed to the connecting pipe 6 below the top sleeve 11, and the threaded sleeve 7 is elastically connected to the top sleeve 11. Specifically, the threaded sleeve 7 is connected to the top sleeve 11 by a spring 12, which is sleeved on the outside of the connecting pipe 6.

[0027] A gap is provided between the side wall of the threaded sleeve 7 and the outer edge of the retaining ring 9 to allow the drain pipe 8 to be inserted.

[0028] A sealing ring 13 is fixed to the inner edge of the side wall of the threaded sleeve 7, and a guide slope is formed on the inner edge of the upper end of the sealing ring 13.

[0029] Both the sealing ring 10 and the sealing ring 13 are made of elastic rubber.

[0030] When it is necessary to connect the connecting pipe 6 to the sewage discharge pipe 8 of the sewage pump 14, insert the retaining ring 9 and the upper part of the connecting pipe 6 into the sewage discharge pipe 8, and then rotate the screw sleeve 7 to make it rotate upward. During the upward rotation of the screw sleeve 7, the top sleeve 11 is driven upward by the spring 12 and squeezes the sealing ring 10. After being squeezed, the sealing ring 10 expands and seals the outer edge of the connecting pipe 6 and the inner edge of the sewage discharge pipe 8.

[0031] Then the screw sleeve 7 continues to rotate upward. When the lower outer edge of the drain pipe 8 contacts the guide slope of the upper end of the sealing ring 13, the sealing ring 13 undergoes elastic deformation and seals the inner edge of the side wall of the screw sleeve 7 and the outer edge of the drain pipe 8 as the screw sleeve 7 continues to rotate upward.

[0032] By setting the spring 12, when the screw sleeve 7 rotates upward and causes the sealing ring 13 to seal the inner edge of the side wall of the screw sleeve 7 and the outer edge of the drain pipe 8, the sealing ring 10 can be prevented from being damaged by the large pressure of the top sleeve 11, and the sealing ring 10 can be effectively protected.

[0033] Wastewater discharged from drain pipe 8 can be collected after being discharged through connecting pipe 6, tee 1, and conduit 15, which can prevent the pump base from being corroded due to prolonged contact between the wastewater and the pump base. The length of conduit 15 can be adjusted as needed.

[0034] Example 2: Based on Example 1, referring to... Figure 1 and Figure 3 As shown, a branch pipe 2 is fixed to the lower end of the tee 1, and a screw 4 is internally threaded onto the branch pipe 2. The lower end of the screw 4 extends to the bottom of the branch pipe 2, and a top plate 5 is rotatably connected to the lower end of the screw 4.

[0035] After the connecting pipe 6 is connected to the sewage pipe 8, the top plate 5 is moved downward by rotating the screw 4. After the top plate 5 contacts the pump base, it can support the tee 1 and the connecting pipe 6, ensuring the stability of the connection between the connecting pipe 6 and the sewage pipe 8.

[0036] Example 3: Based on Example 1, referring to... Figure 4 As shown, when it is necessary to guide sewage from multiple sewage pumps 14 arranged side by side, in this embodiment, the three sewage pumps 14 are arranged horizontally. The plugs 3 on the left and middle tee joints 1 are removed, and then the adjacent two tee joints 1 are connected through the connecting pipe 16. Then, the conduit 15 is fixedly connected to the left tee joint 1. After that, the sewage leaking from the three horizontally arranged sewage pumps 14 can be guided.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
