Description

Technical Field

[0001] This utility model relates to the field of sludge brick making technology, and in particular to a sludge feed hopper for sludge brick making batching. Background Technology

[0002] In the current sludge brick-making batching process, the brick material preparation often follows this procedure: first, the pre-treated sludge blocks are collected and transported to the feed hopper through a specific conveying device. Then, the feed hopper feeds the sludge into the batching machine in an orderly manner, where it is mixed with cement, sand, and other additives in a certain proportion to prepare for the subsequent brick-making process.

[0003] However, these sludge blocks are not pure raw materials; they are usually mixed with various impurities. If sludge blocks containing these impurities are directly mixed with additives to make bricks, it will have an adverse effect on the production quality of the bricks. This will not only affect the appearance quality of the bricks but also weaken their overall performance. Therefore, a sludge feeder for sludge brick making batching is proposed to solve the above problems. Utility Model Content

[0027] Example 1:

[0028] like Figure 1-4 As shown. The present invention proposes a sludge feed hopper for sludge brick making batching, comprising a funnel-shaped feed hopper body 1, wherein a through rectangular opening 2 is provided on one side wall of the feed hopper body 1;

[0029] A first feed side plate 9 and a second feed side plate 10 are spaced apart between the inner walls of the feed inlet at the top of the feed hopper body 1, forming a feed trough between them;

[0030] A sludge crushing assembly is rotatably installed inside the feed trough. The sludge crushing assembly includes an auger 8 that is transversely inserted between the two side walls of the feed hopper body 1, and a first motor 3 that is fixed to the outer wall of the feed hopper body 1 and whose output shaft is coaxially connected to one end of the auger 8.

[0031] The sludge screening plate 7 is inclinedly arranged inside the main body 1 of the feeding hopper. Its high end is hinged to the inner wall of the main body 1 of the feeding hopper, and its low end extends to the outside through the rectangular opening 2. The feeding trough is located above the high end of the sludge screening plate 7.

[0032] The inner wall of the feed hopper body 1 is provided with a vibration assembly that abuts against the bottom of the sludge screening plate 7. The vibration assembly includes a transmission rod 12 that is horizontally installed between the two side walls of the feed hopper body 1, a second motor 4 that is fixed to the outer wall of the feed hopper body 1 and whose output shaft is coaxially connected to one end of the transmission rod 12, and multiple sets of protrusions 11 arranged in a ring array on the outer wall of the transmission rod 12.

[0033] An annular flange 5 is fixed at the bottom outlet of the feed hopper body 1.

[0034] In this embodiment, when in use, the first motor 3 and the second motor 4 are started first. The first motor 3 can drive the auger 8 to rotate, and the second motor 4 can drive the transmission rod 12 to rotate. When the transmission rod 12 rotates, it can drive multiple sets of protrusions 11 to rotate. At this time, the sludge screening plate 7 will vibrate.

[0035] Then the sludge used for brick making is poured into the feed trough, and the rotating auger 8 can prevent some large pieces of sludge from being crushed.

[0036] Then the sludge will fall onto the vibrating sludge screening plate 7. When impurities fall into the sludge screening plate 7 through the feed chute, the vibrating sludge screening plate 7 can screen the sludge used for brick making. The screened sludge can fall down through the screening holes on the sludge screening plate 7, and the impurities can slide down along the inclined surface at the upper end of the sludge screening plate 7, and finally fall down through the lower end of the sludge screening plate 7, thereby collecting these impurities.

[0037] By using point contact, the friction between the protrusion 11 and the sludge screening plate 7 can be reduced to the greatest extent, thereby reducing the wear of both and ensuring good vibration effect. This allows the sludge screening plate 7 to vibrate effectively and improve screening efficiency.

[0038] The side limiting frame 6 can effectively block the sludge, preventing it from sliding off the side of the sludge screening plate 7 during the downward movement, ensuring that the sludge can pass through the screening holes and ensuring the screening effect.

[0039] The annular flange 5 is fixed at the discharge port at the bottom of the feed hopper body 1, and its circumferentially distributed bolt holes can be connected to the feed port of the batching machine through bolts.

[0040] This invention can only screen sludge with a water content of 70% to 95%. At this time, the sludge is semi-fluid or slurry and can be screened through the sludge screening plate 7 under the action of gravity. Both the first motor 3 and the second motor 4 are servo motors.

[0041] Example 2

[0042] As shown in Figure 2. Based on Example 1, this embodiment defines the sludge screening plate 7. The screening holes on the sludge screening plate 7 are located inside the feed hopper body 1, and the angle between them and the horizontal plane is 8°-15°.

[0043] It should be noted that the screening holes on the sludge screening plate 7 are located inside the feed hopper body 1. This is to ensure that the qualified sludge after screening can fall smoothly into the feed hopper body 1 and then be discharged from the bottom outlet for subsequent brick making.

[0044] Furthermore, this angle setting ensures that the sludge slides smoothly under gravity while also ensuring sufficient screening effect.

[0045] Example 3

[0046] As shown in Figure 2, this embodiment, based on Embodiment 1, defines the auger 8, with a 3-5mm gap between the outer periphery of the auger 8 and the inner walls of the first feed side plate 9 and the second feed side plate 10.

[0047] In this embodiment, these gaps ensure that the auger 8 rotates smoothly and effectively prevent sludge from clogging the feed trough.

[0048] Example 4

[0049] As shown in 3-4. Based on Embodiment 1, this embodiment further defines the protrusions 11. Each group of protrusions 11 consists of 3 pieces, and 12-18 groups are equidistantly distributed along the axial direction of the transmission rod 12. The top of the protrusions 11 is in point contact with the bottom of the sludge screening plate 7.

[0050] In this embodiment, point contact can reduce friction while ensuring good vibration performance.

[0051] Example 5

[0052] As shown in 1-2. Based on Embodiment 1, this embodiment further describes the rectangular opening 2. The width of the rectangular opening 2 is greater than the width of the sludge screening plate 7, and a side limiting frame 6 is fixed at the upper edge of the sludge screening plate 7.

[0053] In this embodiment, the side limiting frame 6 can prevent sludge from sliding off the side of the sludge screening plate 7, thus ensuring the screening effect.

[0054] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
