Description

Technical Field

[0001] This utility model relates to the field of ferrous sulfate waste liquid conveying technology, and more specifically, to an anti-clogging structure for ferrous sulfate waste liquid feeding. Background Technology

[0002] Ferrous sulfate has a wide range of applications in many industrial fields. For example, it is used as a flocculant in wastewater treatment to remove suspended solids, heavy metal ions and other impurities from water; in the electroplating industry, it is an important component of electroplating solutions, playing a role in regulating the performance of electroplating solutions and improving electroplating quality. However, a large amount of ferrous sulfate waste liquid is generated during the production and use of ferrous sulfate. In order to recycle and reuse ferrous sulfate waste liquid, it is transported to a belt vacuum filter for recycling.

[0003] Currently, the following problems exist in the process of transporting ferrous sulfate waste liquid: (1) The ferrous sulfate waste liquid stored in the curing tank is pumped into the belt vacuum filter for recovery. However, due to the precipitation of ferrous sulfate at the end of the horizontal pipe, a blockage occurs, which affects the subsequent transportation effect. (2) During the transportation process, ferrous sulfate is prone to precipitate from the solution due to local temperature drop in the horizontal pipe, forming solid crystals. These crystals will gradually adhere to the inner wall of the pipe. Over time, the crystals will accumulate and eventually cause the pipe to become blocked.

[0004] Therefore, we have made improvements and proposed an anti-clogging structure for feeding ferrous sulfate waste liquid. Utility Model Content

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0017] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, this embodiment proposes an anti-clogging structure for feeding ferrous sulfate waste liquid, including a curing tank 1. A conveying pump 2 is provided on one side of the curing tank 1. The input end of the conveying pump 2 is connected to the curing tank 1 through a connecting pipe 3. A horizontal pipe 4 is fixedly connected to the output end of the conveying pump 2. A heating mechanism 5 is provided on the horizontal pipe 4. A vertical pipe 6 is fixedly connected to the upper end face of the horizontal pipe 4 away from the conveying pump 2. A flow sensor 7 is fixedly connected to the upper end face of the vertical pipe 6. A conveying pipe 8 is fixedly connected to the upper end face of the flow sensor 7. An electric butterfly valve 9 is fixedly connected to the outer end face of the horizontal pipe 4. A connecting pipe 10 is fixedly connected to the outer end of the electric butterfly valve 9. A return pump 11 is provided on the outside of the connecting pipe 10. The input end of 1 is fixedly connected to the outer end of the connecting pipe 10, and the output end of the return pump 11 is fixedly connected to the return pipe 12. The end of the return pipe 12 is connected to the curing tank 1, and the return pipe 12 is equipped with a heat preservation mechanism 13. The delivery pump 2 draws out the ferrous sulfate waste liquid in the curing tank 1 through the connecting pipe 3 and delivers it to the horizontal pipe 4, and then delivers it to the delivery pipe 8 through the flow sensor 7. The delivery pipe 8 delivers the ferrous sulfate waste liquid to the belt vacuum filter for recovery. When the flow sensor 7 detects that the flow rate in the horizontal pipe 4 decreases, the electric butterfly valve 9 is opened to start the return pump 11, and the ferrous sulfate at the end of the horizontal pipe 4 is pumped back to the curing tank 1 through the return pipe 12, thereby avoiding the problem of blockage.

[0018] like Figure 1 , Figure 2 and Figure 5 As shown, in a preferred embodiment, based on the above method, the heating mechanism 5 further includes a set of upper sleeves 501 evenly arranged on the horizontal tube 4. The rear end of the upper sleeve 501 is rotatably connected to a lower sleeve 502. A set of heating blocks 503 are fixedly connected at equal intervals on the inner walls of the upper sleeve 501 and the lower sleeve 502. The front ends of the upper sleeve 501 and the lower sleeve 502 are fixedly connected to connecting pieces 504. The upper and lower connecting pieces 504 are connected by a first bolt assembly 505. A junction box 506 is fixedly connected to the upper surface of the upper sleeve 501. When the heating blocks 503 are powered on, they generate heat to heat the ferrous sulfate waste liquid in the horizontal tube 4, preventing the waste liquid from precipitating ferrous sulfate due to temperature drop and clogging the pipe. The junction box 506 is connected to an external power source to power the heating blocks 503. The wiring method between the junction box 506 and the heating blocks 503 and the wiring method between the junction box 506 and the external power source are existing technologies and will not be described in detail here.

[0019] like Figure 1 and Figure 2As shown, in a preferred embodiment, based on the above method, the heat preservation mechanism 13 further includes two heat preservation sleeves 1301 respectively disposed on the thin tube of the return pipe 12. Heat preservation cotton 1302 is fixedly connected to the inner side wall of each of the two heat preservation sleeves 1301. Two fixing ears 1303 are symmetrically and fixedly connected to both ends of the two heat preservation sleeves 1301. The upper and lower fixing ears 1303 are connected by a second bolt assembly 1304. The heat preservation sleeves 1301 and heat preservation cotton 1302 can keep the return pipe 12 warm and prevent the ferrous sulfate waste liquid from precipitating out due to the temperature drop during the return process.

[0020] like Figure 1 and Figure 3 As shown, in a preferred embodiment, based on the above method, a pressure gauge 14 is installed on one side wall of the bottom of the conveying pipe 8, and a temperature sensor 15 is installed on the other side wall of the conveying pipe 8. The pressure gauge 14 is used to detect the pressure of the waste liquid in the conveying pipe 8, to help the operator understand the pressure status in the pipeline and ensure the normal operation of the system. The temperature sensor 15 is used to detect the temperature of the waste liquid in the conveying pipe 8, so as to monitor the temperature change of the waste liquid during the conveying process, ensure that the waste liquid is in a suitable temperature range, and prevent ferrous sulfate from precipitating.

[0021] like Figure 1 , Figure 3 and Figure 4 As shown, in a preferred embodiment, based on the above method, the conveying pipe 8 further adopts a gradually narrowing diameter design. The inner diameter of the starting end of the narrowing section is equal to the inner diameter of the horizontal pipe 4, and the inner diameter gradually decreases to a set value along the waste liquid conveying direction. This can increase the flow rate of waste liquid in the conveying pipe 8, and improve the flow rate within a certain range, which helps to prevent blockage.

[0022] like Figure 1 , Figure 3 and Figure 4 As shown, in a preferred embodiment, based on the above method, the return pipe 12 is further designed with a reduced diameter. The inner diameter of the arc segment of the return pipe 12 is equal to the inner diameter of the horizontal pipe 4. The inner diameter is reduced to a set value along the direction of waste liquid return. This can increase the flow rate of waste liquid in the return pipe 12, enhance the return effect, and better pump the waste liquid at the end of the horizontal pipe 4 back to the curing tank 1.

[0023] Specifically, the anti-clogging structure for feeding ferrous sulfate waste liquid is used as follows: First, the conveying pump 2 is started to extract the ferrous sulfate waste liquid from the curing tank 1 through the connecting pipe 3, and then convey it to the horizontal pipe 4. Then, it is conveyed to the conveying pipe 8 through the flow sensor 7. The conveying pipe 8 conveys the ferrous sulfate waste liquid to the belt vacuum filter for recovery. When the flow sensor 7 detects a decrease in the flow velocity in the horizontal pipe 4, the electric butterfly valve 9 is opened to start the return pump 11, which pumps the ferrous sulfate at the end of the horizontal pipe 4 back to the curing tank 1 through the return pipe 12, thereby avoiding the problem of clogging. When the temperature sensor 15 detects that the temperature of the waste liquid is low, the system supplies power to the heating block 503, so that the heating block 503 heats the horizontal pipe 4, and then heats the ferrous sulfate waste liquid in the horizontal pipe 4, preventing the waste liquid from precipitating ferrous sulfate due to the decrease in temperature and clogging the pipe.

[0024] All technical features in this embodiment can be freely combined according to actual needs.

[0025] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
