Description

Technical Field

[0001] The present invention relates to the technical field of production equipment, and more specifically, to equipment for producing polyferric sulfate and a method for using the equipment. Background Art

[0002] Polyferric sulfate is an inorganic polymer coagulant with superior performance. Its morphology is a light yellow amorphous powdery solid, which is very soluble in water. It is widely used in the purification of drinking water, industrial water, various industrial wastewater, urban sewage, sludge dehydration, etc. In the production process of polyferric sulfate, the waste gas generated needs to be treated by a spray tower before being discharged. The working principle of the spray tower includes: the waste gas enters from the bottom of the cylinder and is discharged from the top. A packing layer is set in the cylinder. The absorbent is sprayed from the top of the cylinder into the packing layer. The rising waste gas and the descending absorbent are constantly in contact in the packing layer to achieve the purpose of absorption and purification. The existing spray equipment has a cylinder that is mostly an integrated structure, which makes it difficult to replace and regularly clean the packing layer inside. The internal packing layer is prone to clogging after long-term use, resulting in a decrease in the spraying effect.

[0003] Between production batches, in order to thoroughly clean the residual polyferric sulfate and impurities on the inner wall of the reactor, a spraying device is used to evenly spray the cleaning liquid on the reactor wall. For example, a high-pressure spray water gun is used to spray alkaline cleaning liquid to remove attached dirt.

[0058] A method for using equipment for producing polyferric sulfate comprises the following steps:

[0059] S1: Scraping and cleaning: The inner wall of the pipe 1 is scraped and cleaned by driving a dual-axis motor to avoid residual chemical residues on the inner wall of the pipe 1, which may affect the normal use of the equipment;

[0060] S2: Auxiliary cleaning: The auxiliary pipe wall cleaning mechanism cleans the pipe wall, and while scraping off the chemical residues on the inner wall of the pipe 1, it sprays clean water for flushing to improve the cleaning effect;

[0062] S4: Nozzle cleaning: Clean the nozzle 2 to prevent chemical residues inside the nozzle 2 from clogging the nozzle and affecting the normal use of the nozzle 2.

[0063] Directions:

[0064] The pipeline 1 of the present equipment is arranged in the polyferric sulfate production equipment. When the pipeline 1 and the reactor need to be cleaned, the inner wall of the reactor can be cleaned by discharging external water into the pipeline 1 and spraying it from the nozzle 2. At the same time, the double-axis motor 4 is started to rotate the threaded rod 6. The thread groove on the outer surface of the threaded rod 6 is a bidirectional thread groove. Therefore, the threaded sleeve 1 9 and the threaded sleeve 2 11 connected by spiral transmission on the outer surface of the threaded rod 6 will move toward each other. The threaded sleeve 1 9 carries two groups of connecting rods 10 to move, and the threaded sleeve 2 11 carries two groups of connecting rods 2 12 to move. The connecting rods 10 and 12 on the same side are both rotatably connected to the corresponding top blocks 13, so the top blocks 13 will be driven to move to both sides. The top blocks 13 push the scraper 15 out of the receiving groove 18 through the flexible transmission rod 17, and scrape the impurities remaining on the inner wall of the pipeline 1.

[0065] At the same time, the two groups of push plates 19 connected by spiral transmission on both sides of the outer surface of the threaded rod 6 will move toward each other, thereby squeezing the airbag 20, so that the cleaning liquid inside the airbag 20 passes through the connecting pipe 23 and the connecting cavity 22. A one-way output valve is provided inside the connecting pipe 23, and the cleaning liquid is sprayed out from the spray hole 21 on the scraper 15, thereby improving the cleaning effect of the scraper 15 on the inner wall of the pipeline 1. When the threaded rod 6 is reversed, the airbag 20 will be pulled. At this time, the airbag 20 will suck the external cleaning liquid into the airbag 20 through the input pipe for replenishment. A one-way input valve is provided inside the input pipe.

[0066] At the same time, the output shaft at the lower end of the dual-axis motor 4 is fixedly connected to the turntable 25, so it will drive the turntable 25 to rotate. A transmission groove 26 is provided on the upper end surface of the turntable 25. The sliding rod 27 slidably connected inside the transmission groove 26 will move as the turntable 25 rotates. The sliding rod 27 is fixedly connected to the limit block 29 in the limit groove 28. Therefore, the sliding rod 27 will drive the nozzle 30 to extend outward, so that the nozzle 30 extends out of the nozzle 2. At the same time, one end of the nozzle 31 on the nozzle 30 is connected to the nozzle 2, and the other end extends outward to expand the spraying range of the nozzle 2. When the cleaning water enters the nozzle 2, a part of it will enter the nozzle 30 through the nozzle 31 and be sprayed from the nozzle 31 extending to the outside, so as to increase the spraying area of ​​the nozzle 2 and improve the cleaning efficiency.

[0067] Secondly, the output shaft at the lower end of the dual-axis motor 4 will also carry the deflection rod 35 to rotate. The other end of the deflection rod 35 is rotatably connected to a rotating rod 37. The gear 38 on the rotating rod 37 is meshed with the gear ring 36, so that the rotating rod 37 will rotate. The rotating rod 37 will carry the transmission wheel 39 to rotate. The transmission wheel 39 is connected to the transmission wheel 2 41 on the rotating rod 2 40 through a belt 42. Therefore, the rotating rod 2 40 will carry the cleaning disk 43 to rotate, and at the same time, it will also revolve with the deflection rod 35, so as to clean the nozzle 2 and prevent the impurities cleaned from clogging the nozzle 2.
