Description

Technical Field

[0001] This utility model relates to the field of chemical technology, and in particular to a settling tank feed buffer device. Background Technology

[0002] In the chemical industry, when raw materials for chemical products (titanium dioxide) are settling, the feed pipe extends into the settling tank to introduce waste liquid into the settling tank, and flocculants are added to carry out settling. The precipitate is located at the bottom of the settling tank.

[0003] During feeding, the waste liquid coming out of the feed pipe will impact the precipitate, causing the precipitate to agitate and be discharged from the overflow port. The agitation causes the overflow liquid to turn white. The overflow port is originally intended to be reused in the crystallization mother liquor. After the precipitate agitates and is discharged from the overflow port, it affects the use of the crystallization mother liquor. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art where, during feeding, the waste liquid coming out of the feed pipe impacts the precipitate, easily causing the precipitate to agitate and be discharged from the overflow port. This agitation causes the overflow liquid to turn white, and since the overflow port is originally intended to be reused in the crystallization mother liquor, the discharge of precipitate from the overflow port affects the use of the crystallization mother liquor. Therefore, a settling tank feed buffer device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A settling tank feeding buffer device includes a settling tank body for settling and a feed pipe for feeding. An overflow pipe for overflow is fixedly installed on one side of the settling tank body and connected to it. The bottom end of the settling tank body is conical. Supports for supporting the settling tank body are fixedly installed on all four sides of the settling tank body. The feed pipe is equipped with a buffer mechanism. When the feed pipe extends into the main body of the settling tank to discharge waste liquid, the buffer mechanism can buffer the waste liquid and reduce the backflow of sediment. In order to adjust the distance between the buffer mechanism and the bottom outlet of the feed pipe, an adjustment mechanism is also included, which can be used to adjust the distance between the buffer mechanism and the bottom outlet of the feed pipe.

[0006] In one possible design, the buffer mechanism includes a large ring and a small circular plate. The large ring is movably fitted onto the feed pipe. Fixed posts are welded to the four sides of the bottom of the large ring. The fixed posts are inclined. The bottom ends of the four fixed posts are welded to the four sides of the top of the small circular plate. The diameter of the small circular plate is larger than the diameter of the feed pipe. The large ring, the small circular plate, and the fixed posts are an integral structure.

[0007] In one possible design, the adjusting mechanism includes a fixed ring, four bolts, and four nuts. The bottom of the fixed ring is welded to the top of the large ring, and they are an integral structure. The fixed ring has flat corners on all four sides, and there are receiving grooves on all four sides of the fixed ring that fit the nuts. The four nuts are welded to the inner walls of the four receiving grooves respectively. The feed pipe has insertion holes on all four sides, and there are multiple sets of insertion holes. The four bolts are threaded to the four nuts respectively, with one end of the bolt inserted into the insertion hole and the other end of the bolt abutting against one side of the fixed ring.

[0008] In one possible design, the bolt is fitted with a washer to improve the bolt's fixing effect.

[0009] In one possible design, the distance between the large ring and the small circular plate is 20 cm.

[0010] In one possible design, the bottom end of the bracket is provided with mounting holes to facilitate the installation and fixing of the bracket.

[0011] In one possible design, the bottom end of the settling tank body is provided with a discharge port and a valve is installed.

[0012] In this application, firstly, the main body of the settling tank is moved to a suitable working position. The support can be securely installed on the ground using bolts, nuts, and other fasteners via the mounting holes at the bottom of the bracket. When it is necessary to adjust the distance between the small circular plate in the buffer mechanism and the bottom outlet of the feed pipe, the large circular ring and the fixed ring in the buffer mechanism are fitted onto the bottom of the feed pipe. The large circular ring and the fixed ring can slide up and down on the surface of the feed pipe, moving to a suitable position as needed. The nut of the fixed ring is aligned with the corresponding insertion hole (there are multiple sets of insertion holes, i.e., multiple rows of insertion holes, with four insertion holes in each row). Initially, the shim is already fitted onto the bolt. Rotating the bolt moves it within the nut, causing one end of the bolt to insert into the corresponding insertion hole in the feed pipe. The bolt and washer are then brought into contact (tightly pressed) with one side of the retaining ring to fix the position of the large ring and the distance between the small circular plate and the bottom outlet of the feed pipe. In use, the external feed pipe (the other end of which is connected to the external wastewater pipe) is inserted into the settling tank to introduce waste liquid into the settling tank. Flocculant is added for settling. The sediment is located at the bottom of the settling tank. When the waste liquid is discharged from the bottom outlet of the feed pipe, it first impacts the small circular plate. Due to the obstruction and buffering of the small circular plate, the flow rate and impact force of the waste liquid are significantly reduced. By not directly impacting the sediment, the sediment is reduced from turning over, so that the liquid discharged from the overflow port can be directly reused in the crystal mother liquor, reducing the impact of the waste liquid on the sediment already settled in the main body of the settling tank.

[0013] The beneficial effects of this utility model are as follows: In this utility model, the settling tank feed buffer device has a buffer mechanism on the feed pipe. When the waste liquid is discharged from the bottom of the feed pipe, it will first impact the small circular plate. Due to the blocking and buffering effect of the small circular plate, the flow rate and impact force of the waste liquid are significantly reduced, avoiding the waste liquid from directly impacting the sediment, thereby greatly reducing the situation of sediment turning over. This helps to maintain the stability of the sediment in the settling tank and improve the settling effect. In this utility model, the settling tank feeding buffer device can conveniently adjust the distance between the buffer mechanism and the bottom outlet of the feed pipe through the adjustment mechanism. In actual use, the distance between the small circular plate and the bottom outlet of the feed pipe can be flexibly adjusted according to the flow rate, velocity, and properties of the waste liquid and the specific conditions of the sediment in the settling tank to achieve the best buffering effect. This adjustability makes the device more widely applicable and can meet the usage requirements under different working conditions. In this invention, the buffer mechanism can block and buffer the waste liquid, preventing direct impact on the precipitate and reducing the precipitate overflow. This allows the liquid discharged from the overflow port to be directly reused in the crystal mother liquor, reducing the impact of the waste liquid on the overflow of the precipitated material in the settling tank. The adjustment mechanism can easily adjust the distance between the buffer mechanism and the bottom outlet of the feed pipe. Attached Figure Description

[0016] 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.

[0017] In one embodiment: Refer to Figure 1-4The feeding buffer device includes: a settling tank body 1, a feed pipe 4, a buffer mechanism, an adjustment mechanism, and supports 3. The settling tank body 1 has a cylindrical structure, with an overflow pipe 2 fixedly installed on one side. The overflow pipe 2 is connected to the interior of the settling tank body 1 and is used to discharge excess liquid from the settling tank. The bottom end of the settling tank body 1 is designed to be conical, which facilitates the accumulation of sediment at the bottom under gravity. Four supports 3 are evenly fixed on the four sides of the settling tank body 1. The feed pipe 4 extends into the settling tank body 1 from the top opening and is used to transport waste liquid into the settling tank.

[0018] The buffer mechanism includes a large circular ring 5, a small circular plate 9, and fixed posts 8 connecting the two. The large circular ring 5 is movably fitted onto the feed pipe 4 and can slide up and down along the surface of the feed pipe 4. Fixed posts 8 are welded to the four sides of the bottom of the large circular ring 5. These fixed posts 8 are inclined, and the bottom ends of the four fixed posts 8 are welded to the four sides of the top of the small circular plate 9, so that the large circular ring 5, the small circular plate 9, and the fixed posts 8 form an integral structure. The diameter of the small circular plate 9 is larger than the diameter of the feed pipe 4. So when the waste liquid is discharged from the bottom end of the feed pipe 4, it will first impact the small circular plate 9. The small circular plate 9 can block and buffer the waste liquid, reduce the flow rate and impact force of the waste liquid, and reduce the impact on the agitation of the sediment. The distance between the large circular ring 5 and the small circular plate 9 is set at 20 cm. This distance can ensure the buffering effect without affecting the normal flow of waste liquid and facilitate the adjustment of the distance between the small circular plate 9 and the bottom opening of the feed pipe 4.

[0019] The adjustment mechanism is used to adjust the distance between the buffer mechanism and the bottom outlet of the feed pipe 4 to adapt to different working conditions. The adjustment mechanism includes a fixing ring 13, four bolts 10, and four nuts 12. The bottom of the fixing ring 13 is welded to the top of the large circular ring 5, forming an integral structure. Flat angles 7 are provided on all four sides of the fixing ring 13 to facilitate the installation and adjustment of the bolts 10 by the operator. Simultaneously, receiving grooves for the nuts 12 are also provided on the four sides of the fixing ring 13, and the four nuts 12 are welded to the inner walls of the four receiving grooves respectively. Multiple sets of insertion holes 6 are provided on all four sides of the feed pipe 4, each set containing four insertion holes 6, distributed along the axial direction of the feed pipe 4.

[0020] When the position of the buffer mechanism needs to be adjusted, the operator first moves the buffer mechanism to its approximate position on the feed pipe 4, aligning the nut 12 on the fixing ring 13 with the corresponding insertion hole 6 on the feed pipe 4. Then, four bolts 10 are passed through the four flat corners 7 on the four sides of the fixing ring 13 and threadedly connected to the nuts 12. Washers 11 are pre-fitted onto the bolts 10. The bolts 10 are rotated to move within the nuts 12 until one end of the bolt 10 is inserted into the corresponding insertion hole 6 on the feed pipe 4, and one end of the bolt 10, the washer 11, and one side of the fixing ring 13 are tightly abutted, thereby fixing the position of the large ring 5 and determining the distance between the buffer mechanism and the bottom outlet of the feed pipe 4.

[0021] This application is for use in the chemical industry, but can also be used in other fields applicable to this application.

[0022] In another embodiment: Reference Figure 1-4 The settling tank feed buffer device is used in the chemical industry. Each bracket 3 has a mounting hole at its bottom. Through these mounting holes, fasteners such as bolts and nuts can be used to securely install the bracket 3 on the ground, thereby providing stable support for the entire device.

[0023] The bottom of the settling tank body 1 is provided with a discharge port for easy discharge and is equipped with a valve, the type of which can be selected according to actual needs.

[0024] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.
