Description

Technical Field

[0001] The utility model relates to a particle membrane cleaning device for treating phosphorus-containing wastewater. Background Art

[0002] With the rapid development of phosphorus chemical enterprises in my country, the treatment of phosphorus-containing wastewater has become a difficult problem in front of us and a major obstacle to phosphorus chemical production. Wastewater treatment is to remove trace substances such as phosphorus, fluorine, ammonia, nitrogen, calcium, silicon, etc. in wastewater. The treatment process generally uses micro-particle membrane filtration first, and then ultra-particle membrane filtration.

[0003] The microparticle membrane used is a high-efficiency, low-cost filter. The membrane needs to be cleaned every three days. The cleaning process is to first remove the filter, then hang out the membrane and soak it in hydrochloric acid for more than 4 hours to complete the cleaning. In this way, the filter will be shut down for more than 4 hours a day, which greatly reduces production efficiency. Utility Model Content

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] like Figures 1 to 3 As shown, a microparticle membrane cleaning device for treating phosphorus-containing wastewater comprises a first cantilever 1 and a second cantilever 2, a filter 3 and a cleaning tank 5 are respectively provided on one side of the first cantilever 1 and the second cantilever 2, dilute hydrochloric acid is provided in the cleaning tank 5, the hook of the second cantilever 2 is connected to a box body 7, a force transmission box 13 is fixedly connected to the lower end of the box body 7, a reduction motor 8 and a force transmission mechanism 4 are respectively installed in the box body 7 and the force transmission box 13, the output shaft of the reduction motor 8 is connected to one end of the force transmission mechanism 4, the other end of the force transmission mechanism 4 is fixedly connected to a suspension rod 12, and acid-resistant slings 9 are respectively connected to both ends of the suspension rod 12.

[0019] The method of using the utility model is:

[0020] The first step: first remove the quick screws on the top cover of the filter 3, and then use the first cantilever crane 1 to lift the top cover of the filter 3 away.

[0021] Step 2: The second cantilever crane 2 rotates to the top of the filter 3, and the acid-resistant sling 9 is connected to the filter element of the filter 3. Then the second cantilever crane 2 hangs the filter element of the filter 3 into the cleaning tank 5, and then the reduction motor 8 drives the filter element to rotate forward and reverse in the cleaning tank 5, so that the particle membrane in the filter element 32 is scrubbed by dilute hydrochloric acid. After 12 minutes, the particle membrane is cleaned.

[0022] Step 3: The second cantilever crane 2 hoists the filter element back into the filter 3, and then the first cantilever crane 1 hoists the top cover of the filter 3 back onto the filter 3, and tightens the quick screws to complete the cleaning process of the particle membrane of the filter 3.

[0023] like Figure 2 and 3 As shown, the force transmission mechanism 4 includes a force transmission shaft 42, a turntable 43 is fixedly connected to the force transmission shaft 42, a plane bearing 44 is provided between the turntable 43 and the force transmission box 13, the upper end of the force transmission shaft 42 is connected to the output shaft of the reduction motor 8 through a coupling 41, and the lower end of the force transmission shaft 42 is fixedly connected to the turntable 43.

[0024] The force transmission mechanism 4 allows the gravity of the filter element to be borne by the plane bearing 44, and the downward gravity of the filter element is not transmitted to the reduction motor 8. At the same time, it can ensure that the filter element can rotate freely to avoid the gravity being transmitted to the reduction motor, which may cause damage to the reduction motor.

[0025] Ear plates 51 are fixedly connected to both ends of the notch of the cleaning tank 5, and two limit rods 52 are fixedly connected to the ear plates 51. Support plates 10 are fixedly connected to both sides of the box body 7, and rib plates 11 are fixedly connected between the support plates 10 and the box body 7. The support plates 10 falling on the ear plates 51 are located between the two limit rods 52. After the second cantilever crane 2 hoists the filter element into the cleaning tank 5, the support plates 10 on both sides of the box body 7 fall on the ear plates 51 at both ends of the notch, and the front and rear sides of the support plates 10 are limited by the limit rods 52. When the reduction motor 8 is started, the support plates 10 will not rotate due to the obstruction of the limit rods 52.

[0026] An aeration pipe 6 is provided at the bottom of the cleaning tank 5. When the microparticle membrane is cleaned, the diluted hydrochloric acid is aerated through the aeration pipe 6, thereby improving the cleaning effect of the microparticle membrane.

[0027] The contents described in the embodiments of this specification are merely an enumeration of the implementation forms of the utility model concept. The protection scope of the utility model should not be deemed to be limited to the specific forms described in the embodiments. The protection scope of the utility model also extends to equivalent technical means that can be thought of by those skilled in the art based on the concept of the utility model.
