Description

Technical Field

[0001] This utility model belongs to the field of chemical technology, and specifically refers to a chemical agent unloading pipe. Background Technology

[0002] Thermal power plants generate a large amount of chemical wastewater during operation, which needs to be treated before discharge. The treatment process requires water treatment equipment to process the chemical wastewater, and therefore various chemical agents are used, such as coagulants, flocculants, bactericides, reducing agents, acids and alkalis. Some of these chemical agents are prepared by the thermal power plant itself. In the process of preparing chemical agents, a reaction vessel is required. Various chemicals are poured into the reaction vessel for stirring and reaction, thereby obtaining the corresponding chemical agents. The feeding and unloading of chemicals are achieved through pipe fittings.

[0003] Currently, the China Patent Network discloses a chemical raw material unloading pipe [Authorization Announcement No.: CN215371377U], which includes a corrugated pipe and C-type quick connectors symmetrically connected to both ends of the corrugated pipe. The C-type quick connector includes a connector and an inner core connected to the connector. The corrugated pipe includes a corrugated section, straight sections symmetrically arranged at both ends of the corrugated section, and a flange connected to the side of the straight section away from the corrugated section. The outer side of the corrugated section is covered with a wear-resistant cloth, and a steel wire is wound around the outer side of the wear-resistant cloth. The inner core is sleeved on the outer side of the straight section, and the flange is arranged on the side of the connector away from the inner core. The end of the steel wire is welded and fixed to the outer surface of the inner core.

[0004] The aforementioned chemical raw material unloading pipe has the following defects: both ends of the corrugated pipe have straight sections, and the ends of the straight sections are turned outward to form flanges. Due to the flanges, the C-type quick connector cannot be fitted onto the corrugated pipe. Therefore, the C-type quick connector must adopt a two-part design, that is, it is formed by splicing two symmetrically arranged C-type quick connector unit blocks. After the two C-type quick connector unit blocks are spliced, they fit exactly on the straight sections and the flanges are located above the connector. This design structure requires the C-type quick connector to be divided into two component units, which makes the production and manufacturing of the C-type quick connector inconvenient. In addition, the connection and fixing structure after the two C-type quick connector unit blocks are spliced ​​must be considered, which further increases the structural complexity of the C-type quick connector. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing a chemical agent unloading pipe. The technical problem to be solved by this utility model is: how to solve the problem of the complex structure of existing connecting parts.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A chemical agent discharge pipe includes a connector and a corrugated pipe made of corrosion-resistant material. The corrugated pipe has an integrally formed straight pipe section at its upper end, with internal threads on the inner circumferential surface of the straight pipe section. The assembly structure also includes a connector and a connecting pipe fitting. The connector has a sleeve portion, with the upper end of the straight pipe section passing through the sleeve portion. The connecting pipe fitting is threaded to the inner circumferential surface of the straight pipe section. The upper end of the connecting pipe fitting has a flange that conforms to the upper surface of the sleeve portion. The connector has a discharge section inserted into the connecting pipe fitting and a clamping portion pressed against the flange. The connector has an installation portion. The connector has two connecting rods penetrating the installation portion, with locking nuts screwed to the upper ends of the connecting rods.

[0008] During assembly, first insert the straight pipe section at the upper end of the corrugated pipe into the sleeve. The sleeve can move up and down along the straight pipe section. Then, thread the connecting fitting onto the inner circumferential surface of the straight pipe section. When assembling the connecting fitting, the connecting piece can be moved downwards to reduce interference between the connecting piece and the connecting fitting installation and improve the ease of installation. After the connecting fitting is installed, move the connecting piece upwards so that the upper surface of the sleeve fits against the flange. Then, insert the connector into the connecting piece, i.e., insert the discharge section into the connecting fitting and press the abutment onto the flange. Then, the connecting rod passes through the mounting part. Finally, screw a lock nut onto the upper end of each connecting rod to clamp the flange between the abutment and the sleeve. This structure modifies the design of the upper end of the corrugated pipe, creating a flange at the upper end after connecting the fittings to the straight pipe section. The assembly method between the fittings and the straight pipe section is simple and efficient, allowing for direct casting of the connectors and facilitating their production. Furthermore, after the discharge section is inserted into the fittings, liquid chemicals enter the corrugated pipe directly from the lower end of the discharge section, preventing direct contact between the flange and the sleeve and thus avoiding leakage.

[0009] In the aforementioned chemical agent unloading pipe, both the mounting part and the clamping part are annular. The connecting member has a mounting sleeve fitted on the outer circumferential surface of the clamping part. Two connecting rods are arranged on the upper end face of the mounting sleeve and are symmetrically arranged from left to right. The mounting part is located above the clamping part. The outer diameter of the mounting part is larger than the outer diameter of the clamping part. The upper end face of the mounting sleeve abuts against the lower surface of the mounting part. The mounting part has a vertically penetrating mounting hole corresponding to the position of the connecting rod, and the connecting rod passes through the corresponding mounting hole.

[0010] In the above-mentioned chemical agent unloading pipe, the inner edge of the lower surface of the sleeve extends downward to form a positioning sleeve. The positioning sleeve is fitted on the outer circumferential surface of the straight pipe section. The positioning sleeve is provided with a number of linear dividing grooves spaced apart along its circumference. An independent clamping arm is formed between two adjacent linear dividing grooves. A clamping hoop is provided on the outer circumferential surface of the positioning sleeve.

[0011] In the aforementioned chemical agent unloading pipe, there are at least two clamps, and all clamps are spaced apart from top to bottom.

[0012] In the aforementioned chemical agent unloading pipe, there is a gap of 20-30 cm between the lower end face of the discharge section and the lower end face of the connecting pipe fitting.

[0013] Compared with the prior art, the chemical agent unloading pipe of this utility model has the following advantages: This structure changes the structural design of the upper end of the corrugated pipe, and after connecting the connecting pipe fitting on the straight pipe section, the upper end of the corrugated pipe forms a flange. At the same time, the assembly method of the connecting pipe fitting and the straight pipe section is simple and has a high assembly effect. This assembly method allows the connecting parts to be directly cast, which facilitates the production and manufacturing of the connecting parts. In addition, after the discharge section is inserted into the connecting pipe fitting, the liquid chemical agent directly enters the corrugated pipe from the lower end of the discharge section. The liquid chemical agent does not directly contact the flange and the sleeve, thus avoiding leakage from between the flange and the sleeve. Attached Figure Description

Detailed Implementation

[0019] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0020] like Figures 1-2As shown, this chemical agent discharge pipe includes a connector 1 and a corrugated pipe 2 made of corrosion-resistant material. The upper end of the corrugated pipe 2 has an integrally formed straight pipe section 20. The inner circumferential surface of the straight pipe section 20 is provided with internal threads. This assembly structure also includes a connector 3 and a connecting pipe 4. The connector 3 has a sleeve portion 30. The upper end of the straight pipe section 20 passes through the sleeve portion 30. The connecting pipe 4 is threaded to the inner circumferential surface of the straight pipe section 20. The upper end of the connecting pipe 4 has a flange 40 that fits against the upper surface of the sleeve portion 30. The connector 1 has a discharge section 10 inserted into the connecting pipe 4 and a pressing portion 11 pressed against the flange 40. The connector 1 has a mounting portion 12. The connector 3 has two connecting rods 31 that pass through the mounting portion 12. The upper end of the connecting rods 31 is screwed with a locking nut 5. During assembly, first insert the straight pipe section 20 at the upper end of the corrugated pipe 2 into the sleeve part 30. The sleeve part 30 can move up and down along the straight pipe section 20. Then, thread the connecting pipe fitting 4 to the inner circumferential surface of the straight pipe section 20. When assembling the connecting pipe fitting 4, the connecting piece 3 can be moved downward to reduce the interference of the connecting piece 3 on the installation of the connecting pipe fitting 4 and improve the convenience of the installation of the connecting pipe fitting 4. After the connecting pipe fitting 4 is installed, move the connecting piece 3 upward so that the upper surface of the sleeve part 30 fits against the flange 40. Then, insert the connector 1 into the connecting piece 3, that is, insert the discharge section 10 into the connecting pipe fitting 4 and press the abutment part 11 against the flange 40. Then, the connecting rod 31 passes through the mounting part 12. Finally, screw the locking nut 5 onto the upper end of each connecting rod 31 so that the abutment part 11 and the sleeve part 30 clamp the flange 40. This structure modifies the structural design of the upper end of the corrugated pipe 2, forming a flange 40 at the upper end of the corrugated pipe 2 after connecting the connecting fitting 4 to the straight pipe section 20. Simultaneously, the assembly method between the connecting fitting 4 and the straight pipe section 20 is simple and has a high assembly efficiency. This assembly method allows the connecting part 3 to be directly cast, facilitating its production. Furthermore, after the discharge section 10 is inserted into the connecting fitting 4, the liquid chemical agent directly enters the corrugated pipe 2 from the lower end of the discharge section 10. The liquid chemical agent does not directly contact the flange 40 and the sleeve part 30, preventing leakage between the flange 40 and the sleeve part 30.

[0021] like Figures 1-4 As shown, both the mounting part 12 and the abutment part 11 are annular. The connecting member 3 has a mounting sleeve 32 fitted onto the outer circumferential surface of the abutment part 11. Two connecting rods 31 are arranged symmetrically on the upper end face of the mounting sleeve 32. The mounting part 12 is located above the abutment part 11, and the outer diameter of the mounting part 12 is larger than the outer diameter of the abutment part 11. The upper end face of the mounting sleeve 32 abuts against the lower surface of the mounting part 12. The mounting part 12 has vertically penetrating mounting holes 120 corresponding to the positions of the connecting rods 31, and the connecting rods 31 pass through the corresponding mounting holes 120. This structure improves the stability of the assembly between the connecting member 3 and the connector 1.

[0022] like Figure 3 and Figure 4 As shown, a positioning sleeve 33 extends downward from the inner edge of the lower surface of the sleeve portion 30. The positioning sleeve 33 is fitted onto the outer circumferential surface of the straight pipe section 20. The positioning sleeve 33 has several linear dividing grooves 34 spaced apart along its circumference. An independent clamping arm 35 is formed between two adjacent linear dividing grooves 34. A clamping clamp 6 is provided on the outer circumferential surface of the positioning sleeve 33. There are at least two clamping clamps 6, and all clamping clamps 6 are spaced apart from top to bottom. The positioning sleeve 33 is composed of several clamping arms 35. After the multiple clamping clamps 6 clamp all the clamping arms 35, the clamping arms 35 have an inward pressing force, which, together with the connecting pipe fitting 4, clamps the straight pipe section 20, thereby ensuring that the threaded connection between the connecting pipe fitting 4 and the straight pipe section 20 is not easy to loosen, and improving the connection stability between the connecting pipe fitting 4 and the straight pipe section 20.

[0023] like Figure 2 As shown, there is a gap of 20-30 cm between the lower end face of the discharge section 10 and the lower end face of the connecting pipe 4. This structure prevents liquid chemical agents from splashing onto the threaded connection between the connecting pipe 4 and the straight pipe section 20 during discharge, ensuring the stability of the connection between the connecting pipe 4 and the straight pipe section 20.

[0024] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
