Description

TECHNICAL FIELD

[0001] The application belongs to the field of high-temperature pumps, and particularly relates to a high-temperature pump bearing bracket liquid and oil discharge structure. BACKGROUND

[0002] During operation of an existing high-temperature pump, leakage of sealing liquid and bearing body lubricating oil into the bearing bracket will occur due to mechanical seal wear. Since the medium transported by the high-temperature pump is usually flammable, explosive, toxic and strongly corrosive, the leaked sealing liquid often carries such hazardous components. However, the bottom of the conventional bearing bracket lacks an effective liquid discharge structure, so that the leaked liquid continuously accumulates in the bracket and cokes due to high temperature, eventually causing serious damage to the bearing. In addition, the high toxicity, strong corrosion and high temperature characteristics of the leaked medium cause the surface temperature of the bearing bracket to rise significantly, making it difficult for on-site personnel to clean and extremely easy to suffer direct personal injuries such as scalding and poisoning. More seriously, the residual flammable liquid in the high-temperature environment may cause a fire or even an explosion accident, posing a great threat to production safety and personnel health. Therefore, it is necessary to solve the above technical problems. CONTENT OF THE UTILITY MODEL

[0003] The purpose of the embodiment of the application is to provide a high-temperature pump bearing bracket liquid and oil discharge structure to solve the problem that the conventional bearing bracket is difficult to effectively discharge liquid and oil.

[0004] To achieve the above purpose, the technical scheme adopted by the application is as follows: a high-temperature pump bearing bracket liquid and oil discharge structure is provided, comprising:

[0005] a bracket body, a recess is formed at a position corresponding to a target high-temperature pump liquid leakage position, and a sunken flow collection groove is formed on the bottom wall of the recess;

[0006] a plurality of branch pipes are arranged corresponding to the recess and are in communication with the flow collection groove, and the branch pipes are vertically arranged;

[0007] a flow collection pipe is horizontally arranged and is in communication with all the branch pipes;

[0008] a containing box is in communication with the flow collection pipe and the branch pipes through the flow collection pipe, and the branch pipes, the flow collection pipe and the containing box are arranged in sequence in the direction of gravity.

[0009] Optionally, a valve for controlling the opening and closing of the flow collection pipe is arranged on the flow collection pipe.

[0010] Optionally, a cover capable of opening the containing box is detachably connected to the containing box, and the cover is in sealing connection with the containing box.

[0011] Optionally, a pressure relief valve capable of being opened when the pressure in the containing box exceeds a threshold value is connected to the containing box.

[0012] Optionally, an outer shell is further connected to the containing box.

[0013] The outer shell cooperates with the containing box to form a cavity for containing the pressure relief valve, and a pressure relief hole is further formed in the outer shell and communicates with the cavity, and the pressure relief hole is oriented perpendicularly to the opening of the pressure relief valve.

[0014] Optionally, a filter core for filtering harmful substances is arranged in the cavity, and the pressure relief valve communicates with the pressure relief hole through the filter core.

[0015] Optionally, the outer part of the branch pipe and / or the collecting pipe is covered with a heat preservation structure capable of heat preservation.

[0016] The high-temperature pump bearing bracket liquid and oil discharge structure provided in the application has the following beneficial effects: compared with the prior art, in the high-temperature pump bearing bracket liquid and oil discharge structure provided in the application, the bracket body forms a groove and a collecting groove is formed by sinking the bottom wall of the groove. Since the branch pipes communicated with the collecting groove and the collecting pipe communicated with all the branch pipes are respectively vertically and horizontally arranged, and since the branch pipes, the collecting pipe, and the containing box communicated with the collecting pipe are sequentially distributed in the direction of gravity, when the target high-temperature pump leaks and the high-temperature medium enters the groove, the leaked medium can automatically enter the collecting groove under the action of gravity and sequentially flow into the containing box through the branch pipes and the collecting pipe. In this way, the problem of accumulation and coking of the leaked liquid in the bracket is avoided, and the site personnel can conveniently transfer the containing box and the toxic and harmful medium collected in the containing box in a safe environment. Therefore, the high-temperature pump bearing bracket liquid and oil discharge structure provided in the application can realize the effects of convenient liquid and oil discharge, which is much better than the prior art.

[0027] According to the above structure provided in the embodiment, in the high-temperature pump bearing bracket liquid and oil discharge structure provided in the embodiment, the bracket body 101 forms a groove 102 and a sunken flow collection groove 103 is formed on the bottom wall of the groove 102. Since the branch pipes 104 communicating with the flow collection groove 103 and the flow collection pipe 105 communicating with all the branch pipes 104 are vertically and horizontally arranged respectively, and since the branch pipes 104, the flow collection pipe 105 and the containing box 106 communicating with the flow collection pipe 105 are sequentially arranged in the direction of gravity, when the target high-temperature pump 200 leaks and the high-temperature medium enters the groove 102, the leaked medium can automatically enter the flow collection groove 103 under the action of gravity and flow into the containing box 106 through the branch pipes 104 and the flow collection pipe 105 in sequence, which not only avoids the problem of accumulated and coked liquid in the bracket, but also enables the site personnel to conveniently transfer the containing box 106 and the toxic medium collected in the containing box 106 in a safe environment. Therefore, the high-temperature pump bearing bracket liquid and oil discharge structure provided in the embodiment can achieve the effect of conveniently discharging liquid and oil, which is much better than the prior art.

[0028] In another embodiment of the present application, please refer to Figure 1 and Figure 2 , a valve 107 for controlling the opening and closing of the flow collection pipe 105 is arranged on the flow collection pipe 105. According to the above structure provided in the embodiment, the valve 107 arranged on the flow collection pipe 105 can conveniently control the opening and closing of the flow collection pipe 105, so that the high-temperature pump bearing bracket liquid and oil discharge structure in the embodiment can achieve a more flexible liquid and oil discharge effect.
