Description

Technical Field

[0001] The present application relates to the technical field of sludge ceramsite screening, and specifically to a sludge ceramsite screening mechanism. Background Art

[0002] Sludge ceramsite is a new type of environmentally friendly material. It is mainly made by high-temperature sintering of sludge from the urban sewage treatment process. During manufacturing, the sludge is usually pretreated first, and then some mixed additives are added and extruded into shape. Finally, the formed sludge is sintered at high temperature to form ceramsite material.

[0003] Sludge ceramsite screening is a crucial step in the production process of sludge ceramsite. Its main purpose is to classify the ceramsite formed after sintering according to size to meet specific application requirements and standards.

[0004] After searching, for example, the patent with publication number CN111112081A specifically discloses a multi-stage screening device for preparing sludge ceramsite, which is provided with an outer sieve cylinder and an inner sieve cylinder to screen the sludge ceramsite.

[0005] During the screening process of sludge ceramsite, a large amount of powder dust will be generated. However, the powder dust generated by most devices will be discharged together with the last layer of ceramsite, which can easily cause dust pollution and is inconvenient to collect the dust uniformly during the screening process. Therefore, it is necessary to provide a sludge ceramsite screening mechanism to solve the above problems.

[0006] It should be noted that the above information disclosed in this Background section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute prior art. Summary of the Invention

[0007] Based on the above-mentioned problems existing in the prior art, the problem to be solved by this application is: to provide a sludge expanded clay screening mechanism, so that the powder dust generated during the screening process will not be discharged together with the last layer of expanded clay, thereby preventing dust pollution and facilitating the unified collection of dust during the screening process.

[0008] The technical solution adopted by the present application to solve the technical problem is: a sludge ceramsite screening mechanism, comprising:

[0009] A screening box is arranged at an angle, and a feed pipe is provided above the high end of the screening box;

[0010] Three groups of filter plates are installed obliquely in the screening box, and the three groups of filter plates are respectively a first filter plate fixed at the uppermost end of the screening box, a second filter plate arranged at the lower end of the first filter plate, and a third filter plate located at the lowermost end of the screening box;

[0011] A collecting hopper is installed at the lower end of the screening box. A collecting pipe is installed at the lower end of the collecting hopper, and a mounting groove is provided on one side of the collecting pipe.

[0012] A spray mechanism is provided in the mounting groove. The spray mechanism has a spray nozzle, and the spray nozzle cooperates with the mounting groove.

[0013] Furthermore, a pipe on one side of the spray nozzle is connected to a water tank, and a water inlet pipe is provided at the other end of the water tank. A fixing plate is fixedly installed between the water tank and the outside of the spray nozzle, and matching holes are provided at both ends of the fixing plate. Fixing holes are provided on both sides of the mounting groove, and the fixing holes and the matching holes correspond to each other. Fixing bolts are threadedly connected to the matching holes and the fixing holes.

[0014] Furthermore, the filter holes of the third filter plate are smaller than the filter holes of the second filter plate, and the filter holes of the second filter plate are smaller than the filter holes of the first filter plate.

[0015] Furthermore, a first channel is fixedly installed on the lower end of the first filter plate, a second channel is fixedly installed on the lower end of the second filter plate, and the second channel is located on one side of the first channel; a third channel is fixedly installed on the lower end of the third filter plate, and the third channel is arranged on one side of the second channel.

[0016] Furthermore, distribution plates are evenly arranged in the feed pipe.

[0017] The beneficial effect of the present application is that the present application provides a sludge expanded clay screening mechanism, which is equipped with a spray mechanism and uses a spray nozzle to spray water mist into the collection pipe, thereby achieving a dust reduction effect. Therefore, the powder dust generated during the screening process will not be discharged along with the last layer of expanded clay, preventing dust pollution, and facilitating the unified collection of dust during the screening process, and performing dust reduction on the collected dust to prevent dust from splashing in the collection pipe.

[0027] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0028] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0029] like Figure 1-Figure 2 As shown, the present application provides a sludge expanded clay screening mechanism, including a screening box 1 and a support frame 11 for fixing the screening box 1. In the present application, the screening box 1 is tilted, and a vibrator is provided on the high end side of the screening box 1. The vibrator is used to vibrate the screening box 1 as a whole. It should be noted that the vibrator is a prior art, and the details can be found in relevant literature, which will not be described here.

[0030] In addition, a feed pipe 12 is provided above the high end of the screening box 1 , and a distribution plate 13 is evenly provided in the feed pipe 12 , so that the distribution plate 13 can prevent the ceramsite from entering the screening box 1 from agglomerating.

[0031] At the same time, three groups of filter plates are installed obliquely in the screening box 1. The three groups of filter plates are respectively a first filter plate 14 fixed to the uppermost end of the screening box 1, a second filter plate 15 arranged at the lower end of the first filter plate 14, and a third filter plate 16 located at the lowermost end of the screening box 1. In this application, the filter hole of the third filter plate 16 is smaller than the filter hole of the second filter plate 15, and the filter hole of the second filter plate 15 is smaller than the filter hole of the first filter plate 14.

[0032] In addition, a first channel 17 is fixedly installed at the lower end of the first filter plate 14, and the first channel 17 is used to discharge and collect the ceramsite screened by the first filter plate 14, and a second channel 18 is fixedly installed at the lower end of the second filter plate 15. The second channel 18 is located on one side of the first channel 17. The second channel 18 is used to discharge and collect the ceramsite screened by the second filter plate 15. At the same time, a third channel 19 is fixedly installed at the lower end of the third filter plate 16. The third channel 19 is arranged on one side of the second channel 18. The third channel 19 is used to discharge and collect the ceramsite screened by the third filter plate 16.

[0033] In the present application, a collecting bucket 2 is fixedly installed at the lower end of the screening box 1, a collecting pipe 21 is fixedly installed at the lower end of the collecting bucket 2, and a collecting box (not shown) is installed at the lower end of the collecting pipe 21. Therefore, the powder dust generated during the screening process is collected by the collecting bucket 2 and discharged into the collecting box through the collecting pipe 21.

[0034] like Figure 2-Figure 3 As shown, in order to prevent dust from splashing at the collection pipe 21, a mounting groove 23 is opened on one side of the collection pipe 21, and a spray mechanism 3 is installed in the mounting groove 23. The spray mechanism 3 has a spray nozzle 32, and the spray nozzle 32 cooperates with the mounting groove 23.

[0035] Furthermore, a pipe on one side of the spray nozzle 32 is connected to a water tank 31, and a water inlet pipe 33 is provided at the other end of the water tank 31, through which water is added to the water tank 31;

[0036] In order to fix the spray nozzle 32, a fixing plate 34 is fixedly installed between the water tank 31 and the outer side of the spray nozzle 32. Matching holes (not marked in the figure) are opened at both ends of the fixing plate 34. At the same time, fixing holes 22 are set on both sides of the installation groove 23. The fixing holes 22 and the matching holes correspond to each other, and the matching holes and the fixing holes 22 are internally threadedly connected with fixing bolts 35, so that the spray nozzle 32 is fixed by the fixing bolts 35.

[0037] In summary, after the sludge ceramsite to be screened enters the screening box 1 through the feed pipe 12, the shaking device is started to shake the screening box 1 as a whole. At this time, the ceramsite slides downward along the first filter plate 14, and the larger ceramsite is screened by the first filter plate 14. The screened ceramsite enters the first channel 17 and is finally collected.

[0038] The remaining ceramsite falls to the second filter plate 15, which screens the medium-sized ceramsite and collects it through the second channel 18. Finally, the smaller ceramsite passes through the third filter plate 16 and falls into the third channel 19.

[0039] During this process, the screened powder dust and unqualified small expanded clay all fall into the collecting bucket 2 and flow into the collecting pipe 21. At this time, the spray mechanism 3 is started and the spray nozzle 32 is used to spray water mist into the collecting pipe 21 to achieve the dust reduction effect. Therefore, the powder dust generated during the screening process will not be discharged together with the last layer of expanded clay, preventing dust pollution. It is convenient to collect the dust uniformly during the screening process, and to reduce the collected dust to prevent the dust from splashing in the collecting pipe 21.

[0040] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
