Description

Technical Field

[0001] The utility model belongs to the technical field of environmental protection, and particularly relates to a transmission device of a feeding device for sludge dewatering. Background Art

[0002] Municipal sludge is the solid precipitate generated during the water treatment process in a sewage treatment plant. It contains a large amount of microorganisms, organic matter, and abundant substances such as nitrogen, phosphorus, and potassium, as well as harmful substances such as bacteria, heavy metals, and pathogenic microorganisms, possessing the dual characteristics of "pollution" and "resource".

[0003] The sludge generated by sewage treatment plants has a relatively high water content (about 80%). By using sludge dewatering equipment to dehydrate through mechanical methods, "mud cakes" with a water content lower than 40% can be obtained.

[0004] When dewatering sludge, the sludge needs to be first sandwiched in the filter cloth, then the filter cloth with the sandwiched sludge is placed in the dewatering device, and then the sludge is dewatered. The Chinese patent document CN215480474U is applied by the applicant, which discloses a feeding device for sludge dewatering. The transmission device of this feeding device for sludge dewatering is a crank - connecting rod mechanism. The motor drives the crank to do uniform circular motion, and then drives the connecting rod to do reciprocating motion. In the uniform circular motion, the time taken to rotate the same angle is equal. Therefore, the forward and backward movement stroke of the connecting rod is equal to the length of the projection of two adjacent points on the equally divided circle, as follows Figure 1 Schematic: This structure has the problem of a large difference in the movement speed of the pull rod during the forward and backward swinging motion. At the front end and the end of the pull rod, as Figure 1 shown, the swing angle is the same from a to f during the stroke, and the time taken is the same, but the projection movement stroke is inconsistent, and the stroke gradually decreases. When the rocker arm moves to the leftmost and rightmost ends, the projection stroke f of the crank - connecting rod rotating circular motion is the shortest and the speed is the slowest. When the connecting rod moves to the middle, the projection of the crank - connecting rod rotating circular motion, that is, the stroke a, is the longest. Therefore, in the middle, the pull rod speed is the fastest. During the entire movement stroke, the speed difference between the front end and the end is too large, resulting in too large a difference in the filter cloth feeding speed at the front and rear ends, and there is a problem of too high a thickness of the filter cloth at the front and rear ends.

[0030] For this reason, the following solutions are proposed:

[0031] See Figure 2 、 Figure 3 , the present utility model provides a transmission device 100 for a feeding device for sludge dewatering. The transmission device 100 is connected to the front and rear swing pull rod 200 of the feeding device for sludge dewatering (i.e., the crank connecting rod 84 in Chinese Patent Document CN215480474U). The transmission device 100 includes a fixing member 110 and a sliding member 120, wherein the sliding member 120 is connected to the front and rear swing pull rod 200.

[0032] Specifically, in the transmission device 100 of the feeding device for sludge dewatering of the present utility model, the fixing member 110 includes a fixing bracket 111 and a driving gear 112 and a driven gear 113 fixed on the fixing bracket 111 and in the same horizontal position. A transmission chain 114 is wound around the driving gear 112 and the driven gear 113.

[0033] In the transmission device 100 of the feeding device for sludge dewatering of the present utility model, the sliding member 120 includes a slider 121, on which a vertically arranged chute 122 is provided. The length of the chute 122 is slightly greater than the spacing of the transmission chain 114 in the vertical direction. A rolling shaft 115 is provided in the chute 122, and the rolling shaft 115 can slide up and down in the chute 122, and the rolling shaft 115 is fixedly connected to the transmission chain 114 of the fixing member 110.

[0034] In the transmission device 100 of the feeding device for sludge dewatering of the present utility model, the driving gear 112 and the driven gear 113 are arranged on the same side of the fixing bracket 111. The transmission chain 114 connects the driving gear 112 and the driven gear 113. The driving gear 112 is the power source of the transmission swing mechanism. The rotating shaft of the driving gear 112 is connected to the external driving motor 300 to drive the driving gear 112 to perform uniform circular motion, and drives the driven gear 113 to perform uniform circular motion through the transmission chain 114 connected between the driving gear 112 and the driven gear 113, so that the transmission chain 114 performs uniform rotational motion around the driving gear 112 and the driven gear 113.

[0035] In the transmission device 100 of the feeding device for sludge dewatering of the present utility model, the plane of the slider 121 of the sliding member 120 is parallel to the plane formed by the driving gear 112, the driven gear 113 and the transmission chain 114 of the fixing member 110. Figure 2 In it, the slider 121 of the sliding member 120 and the driving gear 112, the driven gear 113 and the transmission chain 114 of the fixing member 110 are located on the same side of the fixing bracket 111. The plane formed by the driving gear 112, the driven gear 113 and the transmission chain 114 of the fixing member 110 is located between the plane of the slider 121 of the sliding member 120 and the plane of the fixing bracket 111. A vertical chute 122 is provided on the slider 121, and a rolling shaft 115 is arranged in the chute 122. The rotating shaft of the rolling shaft 115 is parallel to the rotating shafts of the driving gear 112 and the driven gear 113. Its bottom is stuck in the chute 122 of the slider 121, and the top is connected to the transmission chain 114 (for example, fixedly connected to two adjacent pin shafts on the transmission chain 114). Driven by the external driving motor 300, the driving gear 112 is driven to perform uniform circular motion, and drives the driven gear 113 to perform uniform circular motion through the transmission chain 114. The transmission chain 114 performs uniform rotational motion around the driving gear 112 and the driven gear 113. The rolling shaft 115 fixed on the transmission chain 114 performs uniform motion along with the motion of the transmission chain 114, and at the same time drives the slider 121 to move, and the slider 121 performs uniform motion following the motion of the transmission chain 114.

[0036] In some embodiments, the front-back swing pull rod 200 is fixed to the slider 121 of the sliding member 120, and is configured to drive the uniform motion of the front-back swing pull rod 200 through the uniform motion of the slider 121.

[0037] Further, in the transmission device 100 of the feeding device for sludge dewatering of the present utility model, in the fixing member 110, a horizontally arranged upper moving beam 116 and a horizontally arranged lower moving beam 117 are respectively provided at the upper end and the lower end of the fixing bracket 111. In the sliding member 120, it further includes a row of horizontally arranged several upper rolling shafts 123 and a row of horizontally arranged several lower rolling shafts 124 fixed to the slider 121. Among them, the bottom of the upper rolling shaft 123 contacts the top of the upper moving beam 116, the top of the lower rolling shaft 123 contacts the bottom of the lower moving beam 117, and the rotation axes of the upper rolling shaft 123 and the lower rolling shaft 124 are parallel to the rotation axes of the driving gear 112 and the driven gear 113. During the left-right movement of the slider 121 of the sliding member 120, the upper rolling shaft 123 and the lower rolling shaft 124 on the slider 121 respectively perform left-right reciprocating movements on the upper moving beam 116 and the lower moving beam 117 of the fixing bracket 111, which plays a role in restricting the left-right linear movement trajectory of the slider 121 and enables the slider 121 to perform a smooth left-right linear reciprocating movement on the upper moving beam 116 and the lower moving beam 117 of the fixing bracket 111.

[0038] In some embodiments of the present utility model, the sliding member 120 includes two upper rolling shafts 123 and two lower rolling shafts 124. A more preferred implementation manner is that the distance between the two upper rolling shafts 123 is the same as the distance between the two lower rolling shafts 124. Further preferably, the two upper rolling shafts 123 and the two lower rolling shafts 124 are located at the four corners of the rectangular member of the slider 121 of the sliding member 120.

[0039] Driven by the external driving motor 300, the driving gear 112 is driven to perform uniform circular motion, and the driven gear 113 is driven to perform uniform circular motion through the transmission chain 114. The rolling shaft 115 fixedly connected to the transmission chain 114 performs uniform rotational motion along with the movement of the transmission chain 114. The bottom of the rolling shaft 115 is stuck in the chute 122 of the slider 121, driving the slider 121 to perform uniform motion following the movement of the transmission chain 114. The upper rolling shaft 123 and the lower rolling shaft 124 on the slider 121 perform smooth left-right linear reciprocating movements under the restriction of rolling on the upper moving beam 116 and the lower moving beam 117 of the fixing bracket 111. During the process of the transmission chain 114 performing uniform rotational motion around the driving gear 112 and the driven gear 113, the rolling shaft 115 slides up and down in the chute 122 of the slider 121.

[0040] To further improve the smooth left-right linear movement of the slider 121, an upper rolling shaft movement track groove 116a for the upper rolling shaft 123 to roll is provided at the top of the upper moving beam 116, and a lower rolling shaft movement track groove 117a for the lower rolling shaft 124 to roll is provided at the bottom of the lower moving beam 117.

[0041] Through the transmission device 100 of the feeding device for sludge dewatering of the present utility model, a slider 121 that makes a smooth linear reciprocating movement can be obtained, so as to obtain that the slider 121 stably drives the front and rear swing pull rods 200 fixedly connected thereto to make a smooth left-right linear reciprocating movement, solving the problem of too large speed difference during the movement of the front and rear swing pull rods in the prior art, and having the effect of uniform filter cloth feeding speed for the feeding of the feeding device for sludge dewatering. Moreover, the transmission device 100 of the present utility model is completely applicable to the existing sludge dewatering feeding device.

[0042] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
