Description

Technical Field

[0001] The utility model belongs to the technical field of sewage lifters, and in particular relates to an automatic pressure-releasing sewage lifter. Background Art

[0002] A sewage lift is a drainage device used in basements, ships, vehicles and other places that are far away from drainage risers and have poor drainage conditions. It can collect and treat domestic water from the bathroom.

[0003] The Chinese patent with application number CN202022533815.X discloses an automatic pressure relief sewage lifter, which includes a box body, the upper surface of the inner wall of the box body is fixedly connected to the upper surface of the motor, the output shaft of the motor is fixedly connected to the top of the auger, and the bottom end of the auger is fixedly connected to the top of the crushing shaft. By setting up a motor, a separation ring and a confluence chamber, the sewage keeps moving upward under the action of the auger, and at the same time, the garbage is affected by the crushing shaft in the confluence cover, so that it is continuously crushed until the garbage enters the separation ring after being crushed, and the sewage is pumped into it by the sewage pump and then discharged together through the outlet pipe. This method can prevent the waste from passing through the sewage pump, greatly preventing the waste from affecting the sewage pump, and at the same time maintaining stable sewage transmission, and after the garbage is crushed, it can ensure that the subsequent transmission of sewage is smoother.

[0004] However, when the above device is actually used, the crushing shaft is easily entangled with garbage during the process of crushing garbage, which affects the subsequent cutting and crushing of the garbage by the crushing shaft, and after all the garbage is crushed, it enters the check valve pipe through the collection cover. When all the garbage is collected in the check valve pipe, blockage will occur, affecting the processing efficiency of the device.

[0005] In view of this, the present utility model is proposed. Utility Model Content

[0028] See also Figure 1-5 As shown, in this embodiment, a sewage lifter with automatic pressure relief is provided, comprising a box body 1, a separation frame 2 and a collection cover 3 are installed in the box body 1, a rotating rod 5 is rotatably matched in the separation frame 2 and the collection cover 3, a plurality of crushing rods 8 are installed on the circumference of the lower part of the rotating rod 5 located in the collection cover 3, and a motor 4 matched with the rotating rod 5 is installed on the top of the box body 1;

[0029] A cleaning assembly 9 that cooperates with the crushing rod 8 is installed at the bottom of the separation frame 2, a connecting rod 16 is installed at the bottom end of the rotating rod 5, and an inclined rod 17 that cooperates with the inner wall of the collection cover 3 is installed at the bottom end of the connecting rod 16. A water outlet pipe 12 connected to the collection cover 3 is installed in the box body 1, and a sewage pump 13 that cooperates with the water outlet pipe 12 is installed at the bottom of the box body 1, and a pressure relief assembly 14 is installed on the water outlet pipe 12.

[0030] The application of one aspect of this embodiment is as follows: first, the sewage to be treated is input into the separation frame 2, and then the motor 4 is started, so that the motor 4 drives the rotating rod 5 to rotate. The rotating rod 5 rotates to separate the sewage in the separation frame 2 from garbage, so that the garbage enters the collection cover 3, and the sewage enters the bottom of the box body 1. When the rotating rod 5 rotates, it will drive multiple crushing rods 8 to move, so that the multiple crushing rods 8 crush the garbage in the collection cover 3. During the movement of the crushing rods 8, the cleaning component 9 will continuously clean the multiple crushing rods 8 to reduce the situation where the crushing rods 8 are entangled by garbage. The rotation of the rotating rod 5 will drive the connecting rod 16 to rotate, and the rotation of the connecting rod 16 will cause the inclined rod 17 to push the garbage in the collection cover 3 and push the crushed garbage into the outlet pipe 12. The pressure relief component 14 can automatically relieve pressure according to the pressure level in the outlet pipe 12. After the garbage is crushed, the sewage pump 13 is started to extract the sewage at the bottom of the box body 1 into the outlet pipe 12, so that the sewage is connected to the crushed garbage and discharged from the outlet pipe 12.

[0031] By means of the cleaning assembly 9, the rotating rod 5 can drive the crushing rod 8 to crush the garbage inside the collector 3, and the cleaning assembly 9 can clean the crushing rod 8, thereby reducing the situation that the crushing rod 8 is entangled with garbage, and improving the efficiency of crushing garbage by the crushing rod 8. By means of the inclined rod 17, the rotating rod 5 can drive the connecting rod 16 to rotate when it rotates, so that the connecting rod 16 drives the two inclined rods 17 to push the garbage in the collector 3, so that the inclined rod 17 can continuously push the crushed garbage into the outlet pipe 12, reduce the situation that the garbage is blocked by too much garbage, and improve the processing efficiency of the device. By means of the pressure relief assembly 14, when the pressure inside the outlet pipe 12 increases to a certain amount, the pressure relief assembly 14 can discharge the excess gas inside the outlet pipe 12. By means of the separation frame 2, the sewage can be discharged into the separation frame 2, and the motor 4 can drive the rotating rod 5 to separate the sewage in the separation frame 2 from garbage, thereby facilitating the separated garbage to enter the collector 3 for crushing treatment.

[0032] like Figure 5As shown, the cleaning assembly 9 of this embodiment includes a limiting groove 901 provided at the bottom of the separation frame 2, a push rod 902 slidably fitted in the limiting groove 901, and a plurality of cleaning rings 903 installed in the push rod 902 and corresponding to the plurality of crushing rods 8, and the cleaning rings 903 are slidably fitted around the crushing rods 8. The cleaning rings 903 are provided so that when the crushing rods 8 move, the push rods 902 are driven to move by the cleaning rings 903, and the push rods 902 move along the limiting groove 901, so that the push rods 902 drive the cleaning rings 903 to clean the sides of the crushing rods 8.

[0033] like Figure 4 As shown, the pressure relief assembly 14 of this embodiment includes a pressure relief pipe 1401 installed on and connected to the water outlet pipe 12, an exhaust pipe 1402 installed on one side of the pressure relief pipe 1401, a piston 1403 slidably fitted in the pressure relief pipe 1401, and a spring 1404 installed between the top of the inner wall of the pressure relief pipe 1401 and the top of the piston 1403. The piston 1403 can be set to push the piston 1403 when the pressure of the water outlet pipe 12 is too high, so that the gas in the water outlet pipe 12 is discharged through the pressure relief pipe 1401 and the exhaust pipe 1402. When the pressure of the water outlet pipe 12 is relatively low, the spring 1404 drives the piston 1403 to reset by elastic force.

[0034] like Figure 4 As shown, the pressure relief pipe 1401 of this embodiment is provided with an airtight cavity 18, and a float 19 is slidably fitted in the airtight cavity 18. The float 19 can be provided so that when the outlet pipe 12 is draining water, the water flow in the outlet pipe 12 drives the float 19 to seal the airtight cavity 18, thereby reducing the situation where sewage in the outlet pipe 12 enters the pressure relief pipe 1401.

[0035] like Figure 2-3 As shown, a check valve pipe 15 is installed at the bottom of the collector 3 of this embodiment, and the check valve pipe 15 is connected to the outlet pipe 12. Through the check valve pipe 15, the crushed garbage in the collector 3 can enter the outlet pipe 12 through the check valve pipe 15, so that the check valve pipe 15 blocks the garbage in the outlet pipe 12 from entering the collector 3.

[0036] like Figure 1-3 As shown, the rotating rod 5 of this embodiment is located in the upper part of the separation frame 2 and is equipped with an auger 6 on its circumferential side. A separation net 7 is installed in the separation frame 2. The auger 6 is rotatably fitted in the separation net 7. A water inlet pipe 10 is installed on one side of the separation net 7. A guide pipe 11 is installed between the bottom of the box body 1 and the separation frame 2. The auger 6 is arranged so that the rotating rod 5 can drive the auger 6 to rotate, so that the auger 6 drives the garbage in the sewage to move upward, and the garbage is discharged from the top of the separation frame 2 and falls into the confluence cover 3. When the auger 6 rotates, it will stir the sewage to pass through the separation net 7 and the guide pipe 11 and enter the bottom of the box body 1.
