[0030] In addition, the terms "first", "second" and the like are only used for distinguishing description, and cannot be understood as indicating or implying relative importance

[0031] In the description of the utility model, it also needs to be explained that, unless otherwise explicitly specified and limited, the terms "arrange", "connect" and the like should be understood in a broad sense, for example, "connect" can be fixedly connected, can be detachably connected, or integrally connected: can be mechanically connected, can be electrically connected: can be directly connected, or indirectly connected through an intermediate medium, can be the communication inside two elements. For the person skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0032] As shown in the accompanying Figure 1As shown, the existing belt filter device generally includes a conveyor belt, a transmission roller structure 3, a vacuum chamber 4 arranged at the inner side of the conveyor belt; wherein the transmission roller structure 3 mainly includes a driving motor, a driving roller 31 connected with the driving motor, a driven roller 32 erected in parallel with the driving roller 31 and used for driving the transmission of the conveyor belt, and a deviation rectifying structure 33 used for adjusting the transmission position of the conveyor belt; the conveyor belt forms a rotary transmission belt body under the action of the transmission roller structure 3, realizes automatic continuous work, and meets the requirements of industrial production; the vacuum chamber 4 can be a block structure with multiple vacuum chambers distributed along the conveying direction of the conveyor belt, or a continuous structure of a belt type, an external vacuum pump provides power for the vacuum chamber 4, and the vacuum chamber 4 is connected with a liquid discharge separator to recover the liquid at the filter belt.

[0033] The existing belt filter device has the problem that when the vacuum chamber is in active contact with the lower surface of the conveyor belt, the gap between the conveyor and the vacuum chamber becomes larger, resulting in poor filtering effect, so that the conveyor belt needs to be frequently stopped for maintenance, and the replacement frequency of the complete conveyor belt is also higher. Therefore, it has the problems of time-consuming and laborious, high cost.

[0034] The utility model discloses a conveyor belt structure is reformed to realize the purpose of replacing part of filter belt, is favorable for shortening the construction time of maintenance, also is favorable for reducing maintenance cost. In addition, the inventor also finds that the wear and tear of the contact surface of the vacuum chamber and the conveyor belt is greater than that of the conveyor belt surface directly contacted with the raw material, therefore, the conveyor belt structure provided by the utility model can continue to be used by disassembling part of the filter belt and installing it upside down until the wear and tear of both sides is equivalent, further improving the economic benefit.

[0035] As shown in the accompanying drawings Figure 2 - the accompanying drawings Figure 5 As shown in the accompanying drawings

[0036] A belt filter device, comprising a conveyor belt composed of a plurality of filter belts 1 and a connecting belt 2 for connecting adjacent two filter belts 1; the filter belt 1 is provided with filter holes 11; the connecting belt 2 comprises a belt body 21, and at least two fixing columns 22 arranged at both ends of the belt body 21 and penetrating through adjacent two filter belts 1 respectively.

[0037] As some embodiments, the fixed column 22 is fixedly connected with the belt 21 at one end, and has a puncture tip at the other end (i.e. the end away from the belt 21). The puncture tip of the fixed column 22 punctures through the filter belt 1, thereby completing the connection between two adjacent filter belts 1. Preferably, there are multiple fixed columns 22 to improve the connection effect with the filter belt 1. The fixed column 22 can puncture through the filter hole 11 or directly pass through the part of the filter belt 1 other than the filter hole 11. It is worth noting that since the force on the filter belt 1 is the traction force provided by the left and right ends of the transmission roller structure 3 and the downward suction force generated by the vacuum chamber 4, the fixed column 22 can achieve the effect of "stitching" two adjacent filter belts 1 by puncturing upward through the filter belt 1. In use, it is only necessary to ensure that the raw material does not directly hit the fixed column 22.

[0038] As some embodiments, the end of the fixed column 22 away from the belt 21 has a fixed external thread, and a fixed nut 26 connected with the fixed external thread is arranged. At this time, the fixed column 22 passes through the filter hole 11, and the fixed nut 26 is screwed along the fixed column 22 until it abuts against the upper surface of the filter belt 1, thereby ensuring the close fit of the belt 21 and the filter belt 1. Such an embodiment helps to improve the tightness of the connection between two filter belts 1.

[0039] Further preferably, the end of the belt 21 is provided with a sliding groove 24 perpendicular to the conveying direction of the conveyor belt; the connecting belt 2 further comprises an adjusting seat 23 for mounting the fixed column 22 and slidingly connecting with the belt 21. The adjusting seat 23 comprises a moving plate 231 slidingly connected in the sliding groove 24, two clamping members 232 arranged at both ends of the moving plate 231; and the fixed column 22 is mounted on the clamping member 232. Wherein, the sliding groove 24 penetrates through the belt 21, the moving plate 231 slides in the sliding groove 24 and extends out a certain distance from both ends of the belt 21, and the extended part is used to mount the clamping member 232. The advantage of such an arrangement is that it avoids increasing the distance between the belt 21 and the conveyor belt due to the thickness of the clamping member 232 itself. The clamping member 232 functions to clamp the belt 21 together with the moving plate 231, thereby adjusting the position of the moving plate 231 in the sliding groove 24 to adapt to the error in the position distribution of the filter hole 11 in the actual scene.

[0040] As a preferred structure of the clamping member 232, the clamping member 232 comprises a vertical plate 232a arranged at the end of the moving plate 231, a clamping plate 232b arranged on the vertical plate 232a and acting on the upper surface of the belt body 21, and an extension plate 232c arranged on the vertical plate 232a and parallel to the upper surface of the belt body 21 and used for mounting the fixed column 22. The height of the extension plate 232c is higher than that of the clamping plate 232b. The clamping position of the clamping plate 232b is located at the two ends of the conveyor belt to avoid increasing the gap between the conveyor belt and the belt body 21. The height of the extension plate 232c can be consistent with or higher than that of the clamping plate 232b. The upper end of the extension plate 232c extends to the lower surface of the conveyor belt for mounting one or more fixed columns 22. The thickness of the extension plate 232c is less than or equal to 2 mm to reduce the impact of the thickness.

[0041] As some preferred embodiments, the belt body 21 is provided with a chamfer 25 away from the surface end of the fixed column 22. The advantage of such arrangement is to avoid the belt body 21 from colliding with the driving roller or the driven roller when in contact, thereby avoiding the conveyor belt from being jerked and affecting the smoothness of the conveying.

[0042] The specific embodiments described herein are merely illustrative of the spirit of the present application. Those skilled in the art of the present application can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, without deviating from the spirit of the present application or exceeding the scope defined by the appended claims.
