DETAILED DESCRIPTION

[0024] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0025] like Figures 1 to 3 As shown, the embodiment of the utility model provides a metal smelting wastewater treatment device, comprising:

[0026] A first delivery pipe 1;

[0027] The second delivery pipe 2 comprises a connecting pipe 10, a corrugated pipe 8 and a fixed pipe 9 which are connected in sequence. The fixed pipe 9 is provided with a connecting frame 3 which is fixedly connected to the first delivery pipe 1;

[0028] The installation pipe 7 is provided with a filter screen 11 and is passed between the first delivery pipe 1 and the second delivery pipe 2 so that the first delivery pipe 1, the installation pipe 7 and the second delivery pipe 2 form a through passage; and

[0029] The locking assembly comprises a sliding sleeve 4 which is arranged on the connecting pipe 10 and slidably sleeved on the connecting frame 3 and a locking member arranged on the sliding sleeve 4. The locking member is clamped on the connecting frame 3 to keep the corrugated tube 8 in an expanded or contracted state.

[0030] In the embodiment of the utility model, when in use, the first delivery pipe 1 is connected to the front end of the sewage pipe, and the fixed pipe 9 of the second delivery pipe 2 is connected to the rear end of the sewage pipe, so that the channel formed by the first delivery pipe 1, the installation pipe 7 and the second delivery pipe 2 is connected to the sewage pipe, so that the sewage pipe enters the reaction container only after passing through the channel. When the sewage enters the installation pipe 7, the larger impurities present in the sewage can be intercepted by the filter net 11 in the installation pipe 7. The impurities after interception remain in the installation pipe 7, and the impurities contained in the sewage that needs to undergo a chemical reaction are removed to ensure the efficiency of the subsequent reaction.

[0031] Secondly, during long-term interception, in order to ensure the normal passability of the filter screen 11 to ensure the filtering effect, with the cooperation of the sliding sleeve 4 and the locking piece in the locking assembly, the locking piece can be used to release the limit of the sliding sleeve 4, so that the sliding sleeve 4 can slide up and down on the connecting frame 3, so that the sliding sleeve 4 drives the connecting pipe 10 to move toward the fixed pipe 9 and causes the bellows 8 to shrink. When the connecting pipe 10 descends, the mounting pipe 7 is driven down to separate the mounting pipe 7 from the first conveying pipe 1, and finally the mounting pipe 7 can be directly taken out. The mounting pipe 7 can be quickly taken out and the impurities intercepted inside can be cleaned to ensure the efficiency of subsequent processing and the permeability of the filter screen 11. After the processing is completed, the mounting pipe 7 is installed on the connecting pipe 10, and the connecting pipe 10 is lifted upward so that the mounting pipe 7 can be docked with the first conveying pipe 1, and the channel formed by the first conveying pipe 1, the mounting pipe 7 and the second conveying pipe 2 can be re-formed, and the position of the sliding sleeve 4 is fixed by the locking piece to ensure normal use.

[0032] Based on the above scheme, if Figure 4 As shown, the locking member includes a clamping member 19 slidably arranged on the sliding sleeve 4 and a fixing pin 20 arranged on the clamping member 19. The connecting frame 3 is provided with two fixing holes 5, and the fixing pin 20 is clamped in one of the fixing holes 5. Specifically, when the position of the sliding sleeve 4 is released or fixed by the locking member, the clamping member 19 is a U-shaped block structure, and is slidably clamped in the sliding sleeve 4. By sliding the clamping member 19, the clamping member 19 drives the fixing pin 20 provided therein to separate from the corresponding fixing hole 5, and the fixing of the sliding sleeve 4 can be released, and the connecting pipe 10 can be slid downward. In order to avoid excessive pressure on the corrugated pipe 8, a fixing hole 5 can also be opened at the bottom of the connecting frame 3 to fix the sliding sleeve 4, which mainly plays a bearing role, as long as the distance between the installation pipe 7 and the first conveying pipe 1 can remove the installation pipe 7.

[0033] Specifically, a second spring 18 is provided in the clamp 19, and the end of the second spring 18 abuts against the sliding sleeve 4. Under the action of the second spring 18, it can be ensured that the clamp 19 is always subjected to the pressure of the second spring 18 so that the fixing pin 20 provided therein is clamped in the corresponding fixing hole 5, thereby ensuring the stability of the sliding sleeve 4 after installation and ensuring the stability of the mounting tube 7 after installation.

[0034] Based on the above scheme, if Figure 3 As shown, the connecting pipe 10 is provided with a boss 22, the mounting pipe 7 is provided on the boss 22, the first conveying pipe 1 is provided with a mounting ring 21, and the top of the mounting pipe 7 abuts against the mounting ring 21. When the position of the sliding sleeve 4 is fixed, the two ends of the mounting pipe 7 just abut between the boss 22 and the mounting ring 21, thereby ensuring the stability of the mounting pipe 7 after installation and preventing it from jumping.

[0035] Specifically, the filter screen 11 is in an upwardly protruding hemispherical shape. The hemispherical filter screen 11 can increase the contact area of ​​the filter screen 11 in the mounting tube 7. At the same time, impurities intercepted by the filter screen 11 can be guided to the edge of the filter screen 11 on the upwardly protruding arc surface, further ensuring the permeability of the filter screen 11 during operation.

[0036] Specifically, Figure 3 As shown, sealing rings are provided at both ends of the installation tube 7 to increase the sealing performance of the two ends of the installation tube 7 .

[0037] Specifically, Figure 1 As shown, the end of the first delivery pipe 1 and the end of the fixed pipe 9 are both provided with a connecting flange 6, which is convenient for connecting the sewage pipe for easy use.

[0038] Based on the above scheme, if Figure 3 As shown, a limiting frame 14 is provided in the first conveying pipe 1, a valve plug 15 is buckled on the mounting ring 21, the valve plug 15 is provided with a limiting rod 12, the limiting rod 12 is passed through the limiting frame 14, and a first spring 13 is provided, the first spring 13 is located between the valve plug 15 and the limiting frame 14, the mounting tube 7 is provided with a fixing frame 16, and an extrusion rod 17 is provided at the bottom of the valve plug 15, and the fixing frame 16 abuts against the extrusion rod 17 to separate the valve plug 15 from the mounting ring 21.

[0039] In order to more conveniently clean the filter screen 11, when installing the mounting tube 7, that is, when the sliding sleeve 4 drives the mounting tube 7 to move upward, the fixing frame 16 on the mounting tube 7 automatically squeezes the squeezing rod 17 on the valve plug 15, so that the valve plug 15 rises and separates from the mounting ring 21, thereby opening the channel formed by the first delivery pipe 1, the mounting tube 7 and the second delivery pipe 2, and playing the role of opening the valve. When the mounting tube 7 is disassembled, that is, when the mounting tube 7 is driven to move downward by the sliding sleeve 4, the fixing frame 16 is gradually separated from the squeezing rod 17, and the valve plug 15 is squeezed by the first spring 13 and is tightly fastened in the mounting ring 21 again, closing the channel and realizing the role of valve closing, which can stop the flow of sewage in the sewage pipe.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
