Description

Technical Field

[0001] The utility model relates to the technical field of thick slurry pumps, in particular to a thick slurry pump with a liquid leakage alarm function. Background Art

[0002] A thick slurry pump is a single-screw conveying pump. Its main working parts are an eccentric spiral screw and a screw bushing with a double-line spiral surface on the inner surface. It can be used to convey food slurries and corrosive media such as solution slurries and suspensions with a viscosity of 1-1000000 centipoise containing solid particles or colloids. Among them, the stator of a thick slurry pump is prone to cracking after long-term use, causing liquid to leak out of the stator and cause leakage.

[0003] After searching, announcement number CN216306206U discloses a thick slurry pump with a leakage alarm function for liquid material production, comprising a base, a thick slurry pump body fixedly mounted on the upper end surface of the base, a suction pipe provided on the upper end surface of the thick slurry pump body, and one end of a stator provided on the left side of the thick slurry pump body. The thick slurry pump with a leakage alarm function for liquid material production has a sealing tube provided on the outside of the stator, and the two ends of the sealing tube are connected to the stator and flanges 1 and 2 on the outside of the discharge pipe through flange 3, which is convenient for disassembly and assembly. The sealing tube prevents leakage from splashing to the outside, and the leakage in the sealing tube flows into the liquid collection tank through the drain port. A float is provided in the liquid collection tank, and the liquid drives the float upward. The connecting copper bar at the upper end of the float contacts fixed copper bars 1 and 2 on the inside of the liquid collection tank. The power supply is connected to a buzzer through fixed copper bars 1 and 2, and the buzzer alarm is activated to remind the staff to replace it in time. The structure is simple and the cost is low.

[0004] However, in the above solution, the sealing tube is fixed to the outer periphery of the stator by a flange, and the liquid collecting tank for collecting the leaked liquid is of similar size to the sealing tube. In actual use, there is a problem that the sealing tube is inconvenient to remove after the leakage alarm, resulting in low efficiency in stator replacement. In addition, the liquid collecting tank of similar size to the sealing tube needs to wait for the leaked liquid to fill the bottom inside the liquid collecting tank before the circuit conduction alarm is achieved, which easily leads to poor timeliness of the alarm.

[0025] According to an embodiment of the utility model, a thick slurry pump with a liquid leakage alarm function is provided.

[0026] The present invention will now be further described with reference to the accompanying drawings and specific embodiments. Figure 1-4 As shown, according to an embodiment of the present invention, a thick slurry pump with a liquid leakage alarm function includes a thick slurry pump body 1, the upper end face of the thick slurry pump body 1 is connected to a suction pipe 3, and a stator 4 is installed on the surface of the thick slurry pump body 1 through a flange, and the end face of the left end of the thick slurry pump body 1 is connected to a discharge pipe 5, a base 2 is installed below the thick slurry pump body 1, and a funnel shell 6 is fixed on the top surface of the base 2 corresponding to the stator 4, a lower connecting frame 19 is welded at the open top surface of the funnel shell 6, and the bottom of the funnel shell 6 is connected to a square liquid collecting box 12, a sealing shell 7 is installed on the outer cover of the stator 4, and an upper connecting frame 16 connected to the lower connecting frame 19 is welded at the open bottom surface of the sealing shell 7, and mounting holes 9 are respectively provided on the left and right sides of the square liquid collecting box 12, and a conductive copper column 11 is inserted and installed in each of the two mounting holes 9, and two conductive copper columns 11 are inserted and installed in each of the two mounting holes 9. A wire is soldered between the copper pillars 11, and a buzzer 14 and a power supply 15 are installed in series on the surface of the wire. The buzzer 14 and the power supply 15 are connected in series with a wire, and the output end of the power supply 15 is electrically connected to the input end of the buzzer 14 for convenient power supply. In this patent, we only use it and do not improve its structure and function. For those skilled in the art, its setting method, installation method and electrical connection method, as long as they are debugged according to the requirements of its instruction manual, they will not be described in detail here. The funnel shell 6 and the sealing shell 7 also form a barrier structure between the stator 4 and the external environment, reducing the interference of the external environment on leakage detection (for example: liquid splashed in the installation environment of the thick slurry pump body 1 may drip onto the surface of the stator 4. Over time, false alarms of leakage are likely to occur);

[0027] In one embodiment, a first clearance hole 17 is provided on the left side wall of the sealing shell 7 corresponding to the discharge pipe 5, and a second clearance hole 18 is provided on the right side wall of the sealing shell 7 corresponding to the thick slurry pump body 1. The first clearance hole 17 and the second clearance hole 18 are both U-shaped structures. Through the setting of the first clearance hole 17 and the second clearance hole 18, the connection between the sealing shell 7 and the funnel shell 6 is easy, and there is no interference with the structure of the thick slurry pump body 1.

[0028] In one embodiment, a clearance opening 8 is provided on the top surface of the base 2 corresponding to the stator 4, and the square liquid collecting box 12 at the bottom of the funnel shell 6 extends to the inside of the clearance opening 8. The setting of the clearance opening 8 makes room for the square liquid collecting box 12, which is beneficial to the installation of the funnel shell 6.

[0029] In one embodiment, the mounting hole 9 is filled with a rubber sealing ring 10, and the rubber sealing ring 10 is mounted on the surface of the conductive copper column 11. Through the setting of the rubber sealing ring 10, the mounting hole 9 is easy to fill the gap between the mounting hole 9 and the conductive copper column 11, and the waterproof effect is good.

[0030] In one embodiment, the funnel shell 6 as a whole is an inverted hollow quadrangular pyramid structure, and mounting feet 13 are welded on the left and right sides of the funnel shell 6 respectively. Bolts fixed to the base 2 are interspersed on the surface of the mounting feet 13. The setting of the mounting feet 13 makes it easy to fix the funnel shell 6.

[0031] In one embodiment, a drain nozzle is connected to the side of the square liquid collecting box 12, and a manual valve is installed on the surface of the drain nozzle. Through the arrangement of the drain nozzle and the manual valve, it is easy to discharge the leaked liquid in the square liquid collecting box 12, thereby achieving the purpose of turning off the buzzer 14.

[0032] Working principle: First, bolts are used to penetrate the mounting feet 13 and fix them to the base 2, and the funnel shell 6 is fixed under the stator 4. The square liquid collecting box 12 at the bottom of the funnel shell 6 is extended to the clearance opening 8 of the base 2. Then the sealing shell 7 is covered on the periphery of the stator 4, and the upper connecting frame 16 installed at the bottom opening of the sealing shell 7 is connected to the lower connecting frame 19 installed at the top opening of the funnel shell 6 to reduce the interference of the external environment on the leakage detection. When liquid leaks from the stator 4, the dripping liquid is collected in the square liquid collecting box at the bottom of the funnel shell 6 under the diversion effect of the funnel shell 6. 12, when the leaked liquid overflows the two conductive copper pillars 11 installed in the square liquid collecting box 12, the buzzer 14 and the power supply 15 connected in series by a wire are turned on, so that the buzzer 14 emits a buzzer alarm. When the stator 4 is replaced, the funnel shell 6 and the sealing shell 7 connected by the upper connecting frame 16 and the lower connecting frame 19 are easy to disassemble and assemble quickly, which provides convenience for the replacement of the stator 4. The size of the square liquid collecting box 12 arranged at the bottom of the funnel shell 6 is reduced to the greatest extent, and the alarm effect of the buzzer 14 is achieved with the least amount of dripping, which is conducive to increasing the timeliness of the leakage alarm.
