Description

Technical Field

[0001] This utility model relates to the field of sludge separation technology, and more specifically, to a heavy metal sludge solid-liquid separation device. Background Technology

[0002] Industrial wastewater, including production wastewater, industrial sewage, and cooling water, refers to the wastewater and waste liquid generated during industrial production processes. It contains industrial raw materials, intermediate products, by-products, and pollutants lost during production. Industrial wastewater is diverse and complex in composition. For example, wastewater from the electrolytic salt industry contains mercury; wastewater from the heavy metal smelting industry contains lead, cadmium, and other metals; wastewater from the electroplating industry contains cyanide and chromium, among other heavy metals; wastewater from the petroleum refining industry contains phenols; and wastewater from the pesticide manufacturing industry contains various pesticides. Because industrial wastewater often contains multiple toxic substances, it pollutes the environment and poses a significant threat to human health. Therefore, it is essential to develop comprehensive utilization methods to turn harm into benefit, and to implement appropriate purification measures based on the composition and concentration of pollutants in the wastewater before discharge.

[0003] Sludge sample removal involves removing gravel from sludge samples. This process avoids the influence of impurities on the sludge's structure during heavy metal analysis. In heavy metal studies of sludge, a solid-liquid separator is often used to remove water, ensuring the moisture content is within a certain range. Prior to this, impurity separation typically involves filtration using sieves. However, due to the relatively poor fluidity of the sludge, the time it takes to pass through the sieve is long, reducing efficiency. Gravel that cannot pass through the sieve accumulates on its surface, leading to clogging of the sieve's perforations and consequently reducing filtration efficiency and the effectiveness of heavy metal separation. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a heavy metal sludge solid-liquid separation device that can accelerate the flowability of sludge to improve the efficiency and effect of heavy metal sludge separation.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a heavy metal sludge solid-liquid separation device, including a separation chamber, wherein a separation component is provided at the feed inlet of the separation chamber, the separation component includes a screen frame and a cam structure for pushing the screen frame to reciprocate within the separation chamber, the cam structure includes a motor disposed within the separation chamber and a cam body fixedly connected to the output shaft of the motor, the cam structure is provided in two sets and is disposed at both ends of the screen frame, the end of the cam body near the screen frame abuts against the outer wall of the screen frame, a water supply pipe and a high-pressure water gun are provided at one end of the separation chamber corresponding to the screen frame, and the high-pressure water gun is positioned towards the end near the screen frame.

[0006] By adopting the above technical solution, the heavy metal sludge to be separated is poured into the screen frame through the feed inlet of the separation box to achieve separation. In order to accelerate the separation efficiency of the screen frame, the operator needs to turn on the motor of the cam structure, so that the motor drives the cam bodies at both ends to start rotating simultaneously. The protruding part of the cam body at one end will rotate to contact the screen frame and push the screen frame to move in the direction set by the cam body at the other end. At this time, the non-protruding part of the cam body at the other end contacts the outer wall of the screen frame. As the cam bodies at both ends continue to rotate, they push the screen frame to move back and forth in the separation box, thereby increasing the effect of sludge separation. If the screen frame becomes blocked and cannot continue to separate, the operator turns on the external water pump and high-pressure water gun, so that the water supply pipe inputs the external water to the position of the high-pressure water gun. Then, the high-pressure water gun sprays water towards the screen frame. At this time, the water will impact the screen holes of the screen frame to perform preliminary cleaning of the screen holes. The operator can also clean the residual gravel on the screen frame through the feed inlet to prevent the screen frame from becoming blocked, and at the same time improve the efficiency of the screen frame in separating sludge.

[0007] The present invention is further configured such that: both ends of the screen frame are provided with sliding blocks, the separation box is provided with a slide rail for supporting the sliding blocks, the sliding blocks are slidably connected to the slide rail, and the separation box is provided with a driving component for driving the screen frame to slide out from the feed inlet of the separation box.

[0008] By adopting the above technical solution, the cam structure pushes the screen frame to slide within the separation chamber. The sliding block on the screen frame is restricted to the slide rail and slides along the surface of the slide rail. This allows the sliding block to be placed on the screen frame with the support of the slide rail. When the screen frame becomes clogged and cannot separate sludge, the drive component is used to slide the screen frame out of the separation chamber through the feed inlet for cleaning. After cleaning, the drive component slides the screen frame back into the separation chamber and the sliding block slides to the position of contact with the slide rail, thus placing the screen frame and facilitating the screen frame to slide along the surface of the slide rail, thereby improving the efficiency and effectiveness of sludge separation.

[0009] The present invention is further configured such that: a first spring is provided on the slide rail, and the first spring abuts against the sliding block and the inner wall of the separation box.

[0010] By adopting the above technical solution, the first spring abuts against the sliding block of the separation box and the screen frame, so that the screen frame can squeeze the first spring at both ends during the sliding process. The first spring will generate elastic vibration to drive the screen frame to vibrate and shake on the slide rail, thereby improving the screening efficiency of the screen frame. When the two first springs are in the initial position, the area between the two first springs is exactly the width of the sliding block, which facilitates the placement of the screen frame.

[0011] The present invention is further configured such that: a first sliding sleeve and a second sliding sleeve are provided on the outer side of the first spring and are slidably connected to each other, and the first sliding sleeve and the second sliding sleeve are respectively disposed between the outer wall of the screen frame and the inner wall of the separation box.

[0012] By adopting the above technical solution, as the screen frame slides, it can compress the first springs at both ends, causing the first springs to extend and retract within the first and second sliding sleeves. In turn, the first and second sliding sleeves protect the first springs from significant bending or displacement under the compression of the screen frame, thus ensuring the service life of the first springs and improving their working efficiency.

[0013] The present invention is further configured such that: each of the first sliding sleeve and the second sliding sleeve is provided with a mutually abutting limiting block at one end of their respective close proximity.

[0014] By adopting the above technical solution, the first sliding sleeve and the second sliding sleeve will slide against each other, and the limiting block set at one end will block each other, so as not to cause the first sliding sleeve and the second sliding sleeve to separate during sliding. This ensures the sliding efficiency of the first sliding sleeve and the stability of the protection of the first spring, making the contact between the screen frame and the first sliding sleeve more stable.

[0015] The present invention is further configured such that: the diameter of the second sliding sleeve is larger than the diameter of the first sliding sleeve, and a second spring is provided at one end of the first sliding sleeve near the second sliding sleeve, the second spring abutting against the inner wall of the separation box and the first sliding sleeve.

[0016] By adopting the above technical solution, when the first spring extends and retracts with the sliding of the screen frame, the first sliding sleeve and the second sliding sleeve will slide against each other and squeeze the second spring on the first sliding sleeve. This causes the screen frame to generate a moving vibration force and elastic force under the simultaneous action of the first spring and the second spring, thereby increasing the efficiency and effect of the screen frame screening and improving the efficiency of solid-liquid separation of heavy metal sludge. At the same time, it can ensure that the first sliding sleeve and the second sliding sleeve move back to their initial positions under the action of the second spring, and the position of the screen frame is fixed without causing significant impact. This makes it convenient for the screen frame to detach from the slide rail or return to the slide rail.

[0017] The present invention is further configured such that: the driving component includes an electric push rod disposed at the bottom of the screen frame, and the electric push rod is driven toward the end near the discharge port of the separation box.

[0018] By adopting the above technical solution, when the screen frame is blocked, the staff needs to use the extension of the electric push rod to move the screen frame out from the discharge port of the separation box to clean the gravel. After the screen frame is cleaned, the electric push rod is shortened to move the screen frame back into the separation box. The screen frame moves between the two first springs, and when the screen frame moves back into the separation box, it is also between the two first springs and located on the slide rail.

[0019] In summary, this utility model has the following beneficial effects: under the action of the separation component, the flowability of sludge can be accelerated to improve the efficiency and effect of heavy metal sludge separation, and gravel can be prevented from clogging the screen frame and affecting the effect and efficiency of heavy metal sludge separation.

[0026] The present invention will now be described in detail with reference to the accompanying drawings.

[0027] A heavy metal sludge solid-liquid separation device, referring to Figures 1-2 The separation chamber 1 includes a separation assembly located at the feed inlet 2. The separation assembly includes a screen frame 3 and a cam structure for pushing the screen frame 3 to reciprocate within the separation chamber 1. The cam structure includes a motor 7 installed within the separation chamber 1 and a cam body 8 fixedly connected to the output shaft of the motor 7. The cam structure has two sets and is positioned at both ends of the screen frame 3. The end of the cam body 8 closest to the screen frame 3 abuts against the outer wall of the screen frame 3. A water supply pipe and a high-pressure water gun are provided at one end of the separation chamber 1 corresponding to the screen frame 3. The high-pressure water gun is positioned towards the end closest to the screen frame 3.

[0028] Sliding blocks 5 are provided at both ends of the screen frame 3. A slide rail 6 for supporting the sliding blocks 5 is provided inside the separation box 1. The sliding blocks 5 are slidably connected to the slide rail 6. A driving component for driving the screen frame 3 to slide out from the feed inlet 2 of the separation box 1 is provided inside the separation box 1.

[0029] A first spring 11 is provided on the slide rail 6. The first spring 11 abuts against the sliding block 5 and the inner wall of the separation box 1. A first sliding sleeve 10 and a second sliding sleeve 9 are provided on the outside of the first spring 11 and are slidably connected to each other. The first sliding sleeve 10 and the second sliding sleeve 9 are respectively provided between the outer wall of the screen frame 3 and the inner wall of the separation box 1, and the ends of the first sliding sleeve 10 and the second sliding sleeve 9 that are close to each other are provided with mutually abutting limiting blocks.

[0030] The diameter of the second sliding sleeve 9 is larger than the diameter of the first sliding sleeve 10. A second spring 12 is provided at one end of the first sliding sleeve 10 near the second sliding sleeve 9. The second spring 12 abuts against the inner wall of the separation box 1 and the first sliding sleeve 10.

[0031] The driving component includes an electric push rod 4 located at the bottom of the screen frame 3. The electric push rod 4 is not fixedly connected to the screen frame 3, but only extends outward to contact the area of ​​the screen near the sliding block 5. The electric push rod 4 is driven towards the end near the discharge port of the separation box 1.

[0032] Working principle: The heavy metal sludge to be separated is poured into the screen frame 3 through the feed inlet 2 of the separation chamber 1 to achieve separation. To accelerate the separation efficiency of the screen frame 3, the operator needs to turn on the cam-structured motor 7, causing the motor 7 to drive the cam bodies 8 at both ends to rotate simultaneously. The protruding part of one end of the cam body 8 will rotate to contact the screen frame 3 and push the screen frame 3 in the direction set by the other end of the cam body 8. At this time, the non-protruding part of the other end of the cam body 8 contacts the outer wall of the screen frame 3. Thus, as the two ends of the cam body 8 continue to rotate, they push the screen frame 3 to separate the heavy metal sludge. The reciprocating movement within the housing 1 enhances the sludge separation effect. If the screen frame 3 becomes clogged and cannot continue separating, the operator turns on the external water pump and high-pressure water gun, allowing water to be supplied through the water pipe to the high-pressure water gun. The high-pressure water gun then sprays water towards the screen frame 3, which impacts the screen holes of the screen frame 3 to perform preliminary cleaning. The operator can also clean the residual gravel on the screen frame 3 through the feed inlet 2 to prevent clogging and improve the efficiency of the screen frame 3 in separating sludge.

[0033] Under the action of the cam structure, the screen frame 3 is pushed to slide inside the separation box 1. The sliding block 5 on the screen frame 3 is restricted on the slide rail 6 and slides along the surface of the slide rail 6. The sliding block 5 is supported by the slide rail 6 to place the screen frame 3. When the screen frame 3 is blocked and cannot separate sludge, the drive component is used to slide the screen frame 3 out of the separation box 1 through the feed inlet 2 for cleaning. After cleaning, the drive component slides the screen frame 3 back into the separation box 1 and the sliding block 5 slides to the position of contact with the slide rail 6 to place the screen frame 3. This facilitates the sliding of the screen frame 3 along the surface of the slide rail 6, thereby improving the efficiency and effectiveness of the screen frame 3 in separating sludge.

[0034] The first spring 11 abuts against the sliding block 5 of the separation box 1 and the screen frame 3, so that the screen frame 3 can squeeze the first spring 11 at both ends during the sliding process. The first spring 11 will generate elastic vibration to drive the screen frame 3 to vibrate and shake on the slide rail 6, thereby improving the screening efficiency of the screen frame 3. When the two first springs 11 are in the initial position, the area between the two first springs 11 is exactly the width of the sliding block 5, which facilitates the placement of the screen frame 3.

[0035] As the screen frame 3 slides, it can compress the first springs 11 at both ends, causing the first springs 11 to extend and retract within the first sliding sleeve 10 and the second sliding sleeve 9. The first sliding sleeve 10 and the second sliding sleeve 9 then protect the first springs 11 from significant bending or displacement under the compression of the screen frame 3, thus extending their service life and improving their working efficiency. The first sliding sleeves 10 and 9 slide relative to each other, and the limiting blocks at one end prevent them from separating during sliding, ensuring the efficiency of their sliding and the stability of the protection of the first springs 11. This makes the contact between the screen frame 3 and the first sliding sleeve 10 more stable.

[0036] When the first spring 11 extends and retracts as the screen frame 3 slides, the first sliding sleeve 10 and the second sliding sleeve 9 slide against each other, which in turn squeezes the second spring 12 on the first sliding sleeve 10. This causes the screen frame 3 to generate a moving vibration force and elastic force under the simultaneous action of the first spring 11 and the second spring 12, thereby increasing the screening efficiency and effect of the screen frame 3 and improving the efficiency of solid-liquid separation of heavy metal sludge. At the same time, it ensures that the first sliding sleeve 10 and the second sliding sleeve 9 move back to their initial positions under the action of the second spring 12, and the position of the screen frame 3 is fixed without causing significant impact. This makes it convenient for the screen frame 3 to detach from the slide rail 6 or return to the slide rail 6.

[0037] When the screen frame 3 becomes clogged, the operator needs to extend the electric push rod 4 to move the screen frame 3 out of the discharge port of the separation box 1 to clean the gravel. After the screen frame 3 is cleaned, the electric push rod 4 is shortened to move the screen frame 3 back into the separation box 1. The screen frame 3 moves between the two first springs 11, and when the screen frame 3 moves back into the separation box 1, it is also between the two first springs 11 and located on the slide rail 6.

[0038] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
