Description

Technical Field

[0001] This utility model belongs to the field of mineral processing technology, specifically relating to a self-cleaning device for a circulating water pool in a mineral processing workshop. Background Technology

[0002] The circulating water tank in the mineral processing workshop is a core facility for ensuring water recycling in the mineral processing process. Its stable operation directly affects mineral processing efficiency and water resource management costs. Due to the characteristics of mineral slurry, sludge deposition at the bottom of the tank is a common problem. Traditional sludge removal methods mostly use manual cleaning or fixed suction devices, but these methods have technical bottlenecks such as limited suction range, easy pipe blockage, and high energy consumption. Especially when the sludge is unevenly distributed, conventional single-point suction mode cannot achieve complete cleaning of the tank bottom. Residual sludge will accelerate water quality deterioration and increase the frequency of equipment maintenance. Utility Model Content

[0003] To address the problems of numerous dead zones in the existing suction technology, the need for improved anti-clogging performance, and the need to improve suction efficiency, a self-cleaning device for the circulating water tank in a mineral processing workshop is proposed. This utility model provides the following technical solution: A self-cleaning device for a circulating water tank in a mineral processing workshop includes a pump body for pumping sludge. The pump body is connected to a suction head placed at the bottom of the tank via a pipe. The suction head includes a shell with a pipe joint and a suction hole. The shell has a suction cavity for connecting the pipe joint and the suction hole. The shell is spindle-shaped and includes a transition section in the middle and pointed ends at both ends of the transition section. Each pointed end has a suction hole on both sides.

[0004] Preferably, a sieve plate is installed on the suction hole, and the sieve plate is provided with sieve holes.

[0005] Preferably, the suction hole, sieve plate, and sieve hole are all circular.

[0006] Preferably, a flow guide protrusion is fixedly connected to the inner bottom of the housing, and the flow guide protrusion is convex-circular in shape.

[0007] Preferably, the guide protrusion is coaxially arranged with the pipe joint.

[0008] Preferably, the pointed tip is provided with a distance sensor for detecting silt height information.

[0009] Preferably, a protective cover for shielding the upper side of the distance sensor is installed to block the sediment.

[0010] Preferably, the protective cover extends to the edge of the pointed end.

[0011] Preferably, the edges of the upper and lower surfaces of the housing are rounded.

[0012] Preferably, the two sides of the transition portion are arc-shaped.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. Multiple suction holes are set up and face all directions to make the sludge suction range more comprehensive and avoid the formation of suction dead zones; 2. Its shell has a spindle-shaped shape, and the two sides of the transition section are set with rounded arcs. When the pointed head meets the water flow, it effectively reduces water resistance and improves the efficiency of dredging operations. 3. A guide protrusion is fixedly connected to the bottom inner side of the shell. The guide protrusion is convex in shape, which can guide the sludge to gather in the middle of the suction chamber, avoid the sludge from accumulating at the bottom of the shell, and at the same time, the arc surface reduces fluid friction and improves the utilization rate of suction kinetic energy.

Detailed Implementation

[0015] The directional terms mentioned in the following embodiments, such as "up", "down", "left", and "right", are only for reference to the accompanying drawings. Therefore, the directional terms used are for illustration and not for limiting the invention of this utility model.

[0016] like Figure 1-4As shown, a self-cleaning device for a circulating water tank in a mineral processing workshop includes a pump body for pumping sludge. The pump body is connected to a suction head placed at the bottom of the tank via a pipe. The suction head includes a housing 1, on which a pipe joint 14 and suction holes 15 are provided. In this embodiment, the pipe joint 14 adopts an external thread structure. A suction cavity 13 for connecting the pipe joint 14 and the suction holes 15 is provided inside the housing 1. The housing 1 is spindle-shaped, with spindle-shaped flat plates on the upper and lower sides. The side is formed by splicing two arc-shaped plates at the front and rear. The housing 1 includes a transition part 12 in the middle and pointed heads 11 at the left and right ends of the transition part 12. Each pointed head 11 has one suction hole 15 on both sides, for a total of four suction holes 15, which face four directions, so that the sludge suction range is more comprehensive and the suction dead zone is avoided. The spindle-shaped shape of the housing 1 and the arc-shaped arrangement of the two sides of the transition part 12 effectively reduce water resistance and improve the efficiency of sludge removal when the pointed heads 11 meet the water flow.

[0017] Furthermore, a sieve plate 2 is installed on the suction port 15, and the sieve plate 2 is provided with sieve holes 21, which can intercept large particles of impurities from entering the pipeline and prevent the pump body from being blocked. At the same time, the circular sieve hole 21 layout makes the water flow more smoothly and reduces local pressure loss.

[0018] Furthermore, the suction hole 15, the sieve plate 2, and the sieve hole 21 are all circular, which facilitates processing and manufacturing. Moreover, the circular sieve hole 21 has stronger resistance to deformation under the same diameter, and is less prone to deformation during long-term use, thus significantly extending the maintenance cycle.

[0019] Furthermore, a guide protrusion 3 is fixedly connected to the bottom inner side of the shell 1. To save materials, the guide protrusion 3 is made by pressing the plate. The guide protrusion 3 is convex and round in shape, which can guide the sludge to gather in the middle of the suction cavity 13, avoid the sludge from accumulating at the bottom of the shell 1, and at the same time, the arc surface reduces fluid friction and improves the utilization rate of suction kinetic energy.

[0020] Furthermore, the flow guide protrusion 3 is coaxially arranged with the pipe joint 14 to ensure that the fluid maintains axial flow characteristics when entering the pipe, reduce turbulence generation, significantly reduce pipe vibration and noise, and improve the stability of equipment operation.

[0021] Furthermore, a distance sensor 4 for detecting silt height information is provided on the pointed head 11, and it faces away from the transition part 12. It can monitor in real time and accurately control the timing of dredging operations to avoid over-sucking or under-sucking. With the help of the intelligent control system, it can realize automatic start and stop. Specifically, the URM08-RS485 waterproof ultrasonic ranging sensor can be used. Its specific control principle is a mature existing technology, so it will not be described in detail.

[0022] Furthermore, a protective cover 5 is installed on the upper side of the distance sensor 4 to shield it from sediment, effectively preventing sediment particles from directly impacting the sensor surface, extending the sensor's service life, and maintaining detection accuracy unaffected by environmental interference.

[0023] Furthermore, the protective cover 5 extends to the edge of the pointed head 11, eliminating blind spots and maintaining reliable protection even when the water flow is turbulent, significantly reducing the equipment failure rate.

[0024] Furthermore, the edges of the upper and lower surfaces of the housing 1 are rounded to reduce friction between the housing 1 and the deposits, reduce wear, and facilitate the smooth settling of the deposits, preventing them from accumulating at the working end of the distance sensor 4.
