Description

Technical Field

[0001] The invention relates to the technical field of industrial production cleaning and environmental protection equipment, and in particular to a liquid medicine sediment adsorption head and a sediment cleaning device. Background Art

[0002] There are many process steps in mechanical processing production that need to be carried out in liquid medicine, such as electrolysis, electroplating, acid etching, alkali etching, oxidation, dyeing, etc. In large-scale industrial production, a larger reaction tank is usually set up, and the corresponding liquid medicine is poured into the reaction tank. The workpiece that needs to be electroplated, acid-etched, and oxidized is immersed in the liquid medicine in the reaction tank for relevant process reactions. After long-term use, impurities will inevitably appear in the reaction tank. These impurities are deposited at the bottom of the reaction tank and affect the stability of the chemical parameters of the liquid medicine.

[0003] There are two ways to clean these deposited impurities: (1) Empty the liquid medicine in the reaction tank and then clean it. The advantages of this method are: thorough cleaning and low operating difficulty. The disadvantages are high cost, the emptied liquid medicine usually has to be scrapped, and the operation time is long. Emptying the liquid medicine, cleaning, and refilling the liquid medicine all take a lot of time, and the process cannot be terminated. During this period, the reaction tank cannot resume production. (2) Keep the liquid medicine in the reaction tank and use equipment to directly clean the sediment at the bottom of the reaction tank.

[0004] In the prior art, the underwater sediment can be cleaned by using a scraper, a sludge suction machine and an air lift device. The scraper is installed at the bottom of the pool, and the scraper collects the sludge into the hopper for easy discharge. The scraper is easy to operate, maintain and has high efficiency, but it needs to be installed in place when the reaction pool is built.

[0005] The sludge suction machine sucks the mud into the pipeline through vacuum or siphon principle and transports it to the mud discharge system. The advantages of the sludge suction machine are its simple structure and high efficiency. The disadvantages are that it can only clean thin and loose sediments, and the sludge suction machine will suck away a large amount of liquid medicine.

[0006] The air lift device injects compressed air into the water to form rising bubbles, and uses the buoyancy disturbance and lifting effect of the bubbles to bring the bottom sediments (including silt and sediments) to the surface of the water. This method has low energy consumption, but it has a large disturbance to the liquid medicine, and is not effective for sediments that are more firmly attached.

[0007] There are also some such as underwater cleaning robots and high-pressure jet cleaning equipment, which are only suitable for cleaning sediments on the bottom of the water and are difficult to use in the liquid environment of industrial reaction tanks. Summary of the invention

The brush rollers can be driven to rotate by a cleaning brush driver, and the bristles at the bottom of the brush rollers move toward the direction of the adsorption head.

[0022] Applying the above-mentioned drug liquid sediment adsorption head, the present invention also provides a drug liquid sediment adsorption device, including a body, a walking system, a servo system, a support arm and an adsorption head; wherein the adsorption head is the drug liquid sediment adsorption head provided in the above-mentioned present invention.

[0031] In the traditional underwater sediment cleaning process, sediment is transported using liquid as the transport medium. During the cleaning process, a large amount of liquid will be sucked away at the same time as the sediment is sucked away. Sediments that have been deposited for a longer time and are harder in texture require scrapers or other tools to loosen the sediments, and then the loosened sediments are sucked away. Because during the sediment loosening process, scrapers and other tools will disturb the water body and accelerate the sediment to drift around. In order to prevent the sediment from drifting, it is necessary to increase the flow rate of the sucked liquid and suck away more liquid. Otherwise, the sediment will be carried to a position far away from the adsorption head by the disturbed liquid during the loosening process, and will re-attach to the bottom of the pool after standing, affecting the sediment cleaning effect.

[0032] The above technical solution of the present invention is applied to a liquid medicine sediment adsorption head, which has the following effects: the present invention first sets a water-proof cover outside the adsorption port, the opening of the water-proof cover is downwardly covered on the bottom of the reaction pool, and the water-proof cover and the pool bottom together form a closed positive pressure chamber. Gas is blown into the water-proof cover by a blowing pipe. As long as the air flow rate blown into the positive pressure chamber by the blowing pipe is greater than the gas flow rate sucked away from the positive pressure chamber by the suction pipe, the pressure in the positive pressure chamber is greater than the surrounding water pressure, and the positive pressure chamber is filled with gas, and the excess gas is discharged from the gap between the bottom edge of the water-proof cover and the pool bottom.

[0033] The suction pipe uses the air in the positive pressure chamber as a medium to absorb the sediment. In order to facilitate the absorption of hard sediment, a cleaning brush is set around the suction port in the positive pressure chamber. The bristles of the cleaning brush scrape off the sediment and then suck it away by the suction pipe. The water-proof cover will block the sediment scraped by the cleaning brush to prevent it from splashing everywhere. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0038] The present invention provides a liquid medicine sediment adsorption head, such as Figure 1 As shown, it includes an air suction pipe 2, an air blowing pipe 3, a water-proof cover 1 and a cleaning brush 4.

[0039] The suction pipe 2 is used to suck away the sediment. The suction pipe 2 has a suction port at the bottom, and the suction pipe 2 is connected to a negative pressure source. The negative pressure source is a device that can generate vacuum negative pressure. This application is a sludge cleaning device, and reference can be made to existing sludge cleaning devices.

[0040] The water-blocking cover 1 is installed at the bottom of the air suction pipe 2. The top of the water-blocking cover 1 is sleeved on the air suction pipe 2 and sealed, and the bottom is open. The water-blocking cover 1 is inverted on the bottom of the pool in a bowl shape. The water-blocking cover 1 and the bottom of the pool enclose a positive pressure chamber 5, and the suction port is opened downward and placed in the positive pressure chamber 5.

[0041] The air blowing pipe 3 is connected to the positive pressure source. The air blowing pipe 3 has a plurality of air outlets 6c. The air outlets 6c are arranged around the bottom edge of the waterproof cover 1.

[0042] The cleaning brush 4 is installed in the water-proof cover 1 and is arranged around the adsorption port. The cleaning brush 4 is driven by a cleaning brush driver to scrape the sediment on the bottom of the pool.

[0043] The suction pipe 2 needs to suck away the sediment while transmitting the airflow, so the inner wall of the suction pipe 2 needs to be kept as smooth as possible, and reduce bending, especially large-angle bending, to prevent sediment from being deposited in the suction pipe 2. The blowing pipe 3 only needs to be able to stably transmit the airflow, and an ordinary hose can be used.

[0044] The water shield 1 is in the shape of an inverted bowl, and a suction port and a cleaning brush 4 are arranged inside the water shield 1. The water shield 1 is usually made of stainless steel or hard plastic. The top opening of the water shield 1 allows the air suction pipe 2 to pass through. The air suction pipe 2 extends from the top of the water shield to the positive pressure chamber 5 of the water shield 1. The air blowing pipe 3 passes through the top of the water shield 1 and is sealed to prevent air leakage or liquid leakage.

[0045] Since some sediments have been deposited for a long time and are relatively hard, liquid can be used as a medium to absorb and clean them better. However, if gas is used as a medium, the adsorption effect on the sediments is weakened. Therefore, a cleaning brush 4 is arranged around the adsorption port, and the bristles of the cleaning brush 4 can scrape the sediments on the bottom of the pool to loosen them and facilitate adsorption. A plurality of scrapers can also be arranged outside the cleaning brush 4, and the scrapers have the same function as the cleaning brush 4. The cleaning brush 4 can be driven by a cleaning brush driver to move or rotate, thereby increasing the cleaning ability of the cleaning brush 4. The bristles of the cleaning brush 4 are preferably made of metal.

[0046] In order to ensure that the adsorption head of the present invention can work normally underwater, it is necessary to maintain a gas environment in the positive pressure chamber 5 in the watertight cover 1, and the liquid needs to be discharged outside the watertight cover 1. This requires that the amount of air blown into the watertight cover 1 by the blowing pipe 3 is greater than the amount of air sucked away by the suction pipe 2. An intake flow sensor and an intake flow control valve are provided on the blowing pipe 3, and an intake flow sensor and an intake flow control valve are provided on the suction pipe 2, and the intake flow of the blowing pipe 3 is greater than the intake flow of the suction pipe 2.

[0047] After the sediment is deposited, the bottom of the reaction pool will be uneven, and the adsorption head needs to move on the bottom of the reaction pool. If the intake flow rate and the outlet flow rate are kept the same, it is easy to inhale a large amount of liquid. After experiments, it was found that making the intake flow rate greater than the suction flow rate can effectively reduce the amount of liquid medicine inhaled by the suction pipe 2. The excess of the intake flow rate minus the suction flow rate will be discharged from the bottom edge of the water-proof cover. Since the floating of the exhausted gas will also cause disturbances to the liquid in the reaction pool, the intake flow rate should not exceed the suction flow rate too much. After experiments, it is more appropriate for the intake flow rate to be 102%-105% of the suction flow rate.

[0048] In order to reduce the amount of liquid flowing into the bottom of the adsorption port, the bottom edge of the water-blocking cover 1 should be as close to the pool bottom as possible. Since the sediments on the pool bottom will make the pool bottom uneven after being deposited, if the water-blocking cover 1 is too low, its edge will scratch the sediments and push the sediments to the sides of the water-blocking cover 1, affecting the cleaning effect. If the water-blocking cover 1 is too high, the gap between the water-blocking cover 1 and the pool bottom will be too large, which will absorb a large amount of liquid medicine. Therefore, an annular enclosure 6 is installed on the lower edge of the water-blocking cover 1. The enclosure 6 is made of elastic deformable material. When working, the bottom of the enclosure 6 contacts the pool bottom. The enclosure 6 itself is deformable and can adapt to the uneven environment of the pool bottom. When the adsorption head moves on the bottom of the pool, the flexible enclosure 6 will not scratch the sediments, but will slide over the top of the sediments after deformation, so that the sediments can smoothly contact the adsorption port and the cleaning brush 4.

[0049] The enclosure 6 includes an inner layer 6a and an outer layer 6b. A cavity is left between the inner layer 6a and the outer layer 6b. The tops of the inner layer 6a and the outer layer 6b are fixed at the lower edge of the water barrier 1, and the bottoms of the inner layer 6a and the outer layer 6b are connected and fused together. The cross section of the enclosure is a cone that is wide at the top and narrow at the bottom. The bottom of the enclosure is easier to deform, which is conducive to the enclosure fitting the uneven bottom of the pool. The air pipe 3 is connected to the cavity in the enclosure 6, and the air outlet 6c connecting the cavity and the positive pressure chamber 5 is opened around the inner layer 6a.

[0050] The cleaning brush 4 is arranged around the suction port, and the height of the cleaning brush 4 is adjustable. The height of the cleaning brush 4 is manually adjusted. When in use, the appropriate height is adjusted according to the state of the pool bottom. The cleaning brush driver is a motor that drives the cleaning brush 4 to rotate. The present invention proposes two specific arrangements of the cleaning brush 4, which are as follows:

[0051] (1) The cleaning brush 4 is a plurality of disc-shaped brush heads arranged around the suction port, the bristles of the disc-shaped brush heads face downward and can be driven by the cleaning brush driver to rotate along the axis.

[0052] (2) The cleaning brush 4 is a plurality of brush rollers arranged transversely, which are connected end to end and arranged around the adsorption head. The brush rollers can be driven to rotate by a cleaning brush driver, and the bristles at the bottom of the brush rollers move toward the direction of the adsorption head.

[0053] Based on the adsorption head proposed above, the present invention also provides a liquid medicine sediment adsorption device, such as Figure 2 As shown, the adsorption device includes a body 9, a walking system 11, a servo system 10, a support arm 7 and the adsorption head proposed in the above text of the present invention.

[0055] The machine body 9 is also provided with a positive pressure source and a negative pressure source. The positive pressure source is connected to the air blowing pipe 3, and the negative pressure source is connected to the air suction pipe 2.

[0056] A sediment separator is also provided between the negative pressure source and the adsorption head. The sediment separator has an expanded flow channel. The gas mixed with sediment has a reduced flow velocity in the sediment separator, and the sediment is deposited downward, and the airflow reaches the negative pressure source from the top. The sediment separator is also connected to a dehydrator to reduce the water content of the sediment solids. The liquid and solid in the sediment are separated, the liquid is stored in a waste liquid storage tank, and the solid is stored in a storage box.

[0057] The servo system 10 is responsible for carrying the adsorption head to move, and the servo system 10 can be a mechanical arm or a three-axis translation servo system 10.

[0058] The upper end of the support arm 7 is connected to the servo system 10, and the bottom of the support arm 7 is connected to the adsorption head. When working, the top of the support arm 7 is above the liquid surface, the bottom of the support arm 7 and the adsorption head are immersed below the liquid surface, and the adsorption head is in close contact with the bottom of the pool. A flange is provided on the top of the support arm 7, and the support arm 7 is detachably connected to the servo system 10 through the flange. The bottom of the support arm 7 is provided with an angle-adjustable elbow, and the adsorption head is detachably connected to the support arm 7 through the elbow. When working, the support arm 7 is tilted.

[0059] In order to improve the lifting capacity of the sediment, the support arm 7 is configured as a hollow tube, the top of the support arm 7 is connected to the negative pressure source through a pipeline, and the bottom of the support arm 7 is connected to the suction pipe 2. The support arm 7 can also be regarded as a part of the suction pipe 2. In short, the suction airflow flows through the support arm 7.

[0060] A spiral conveying rod 8 is arranged inside the support arm 7, and a driving motor is fixed on the top of the support arm 7, and the driving motor drives the spiral conveying rod to rotate. Smaller sediments will be directly blown to the top along the support arm 7 by the airflow, and for larger sediments, or sediments deposited in the adsorption head or the support arm 7, the spiral conveying rod 8 will assist the sediments to rise, and after being lifted to the top, they will be carried away laterally by the airflow.

[0061] An air outlet 6c is provided on the top side of the support arm 7, and the air outlet 6c is connected to the negative pressure source through a pipeline, and the bottom opening of the support arm 7 is connected to the adsorption port of the adsorption head.

[0062] A controller is provided on the machine body 9, and the controller is electrically connected to the intake flow sensor, the intake flow control valve, the intake flow sensor and the intake flow control valve respectively; the intake flow sensor and the intake flow sensor send the collected data to the controller, and the controller controls the opening and closing of the intake flow control valve and the intake flow control valve to control the intake flow and the intake flow, and maintains the intake flow at 102%-105% of the intake flow.
