Description

Technical Field

[0001] The present invention relates to the technical field of tandem spiral filter presses, and in particular to a tandem spiral filter press capable of avoiding feed blockage. Background Art

[0002] The tandem spiral filter press, or spiral filter press for short, first appeared in Germany in the 1960s. In recent years, it has been widely used in sludge dewatering and other industrial process dewatering fields. In recent years, spiral filter press has been developed, innovated and promoted in my country. Its working principle is that when the spiral driving shaft rotates, the multiple fixed and active laminates arranged on the outer periphery of the driving shaft move relatively. Under the action of gravity, water is filtered out from the gaps between the relatively moving laminates to achieve rapid concentration; the concentrated sludge moves forward continuously with the rotation of the spiral shaft; along the direction of the mud cake outlet, the pitch of the spiral shaft gradually decreases, the gap between the rings also gradually decreases, and the volume of the spiral cavity continues to shrink; under the action of the back pressure plate at the outlet, the internal pressure gradually increases, and under the continuous operation of the spiral driving shaft, the water in the sludge is squeezed out, and finally the continuous dewatering of the sludge is achieved.

[0003] However, the existing tandem spiral filter press often blocks the feed inlet during use because the slurry it transports has a high viscosity and is sometimes accompanied by large condensates, forcing the tandem spiral filter press to stop working and affecting work efficiency. In view of this, a tandem spiral filter press that can avoid feed blockage is proposed. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention provides a series-stacked spiral filter press that can avoid feed blockage, thereby solving the problems raised in the above-mentioned background technology.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a cascade-stacked spiral filter press that can avoid feed blockage, comprising a support table, a motor bracket is fixed above the support table, a three-phase motor is fixed on the motor bracket, a body is fixed above the support table, a support frame is fixed above the body, a negative pressure plate is fixed at the rear of the body, a feed cover is fixed above the support frame, a leakage pipe is fixed at the bottom of the feed cover, a power rod is fixed at the output end of the three-phase motor, the power rod completely penetrates and rotates on the body, a rotating vane is fixed on the power rod, a dehydration filter screen and a static sheet ring are fixed on the inner wall of the body, a transmission rod completely penetrates and slides on the body, a moving sheet ring is sleeved on the transmission rod, and the moving sheet ring and the static sheet ring are attached to each other and alternately arranged in multiple groups. The feed cover is provided with a stirring device, a pounding device is provided inside the feed cover, and a knocking device is fixed to the bottom of the feed cover; wherein the stirring device comprises a driving wheel, a belt, a transmission wheel, a rotating rod, a sliding spring, a stirring blade, a moving block and a static block, the driving wheel is sleeved on the power rod, the rotating rod penetrates and rotates on the feed cover, the rotating rod is sleeved with a transmission wheel, and the transmission wheel is connected to the driving wheel through a belt drive.

[0006] According to the above technical scheme, a stirring blade is sleeved and slidably arranged on the rotating rod, one side of the sliding spring is fixed to the side wall of the stirring blade, and the other side of the sliding spring is fitted to the inner wall of the feed cover, and a moving block is fixed to the end point of the stirring blade, and the static block is fixed on the feed cover and fits to the surface of the rotating rod. When the three-phase motor is working, when the end point of the stirring blade in the stirring device rotates and contacts the pressure rod, the downward force applied to the pressure rod forces the pressure rod to move downward, and the downward movement of the pressure rod brings the wolf tooth rod downward, and the wolf tooth rod moves downward, bringing the coarse particles in the material to be pounded downward, and the coarse particles will not block the leakage pipe, making the material transmission smoother. As the end point of the stirring blade moves away from the pressure rod, the pressure rod will be reset due to the pulling force of spring one and spring two. When the stirring blade keeps rotating, the end point of the stirring blade keeps contacting and moving away from the pressure rod, causing the wolf tooth rod to pound back and forth up and down, bringing the coarse particles downward.

[0007] According to the above technical solution, the pounding device includes a support rod, a pressure rod, spring one, spring two and a wolf tooth rod. The support rod is fixed at the bottom of the feed cover. The support rod is penetrated and slid with a pressure rod. The wolf tooth rod is fixed on the pressure rod. When the three-phase motor is working, when the end point of the stirring blade in the stirring device rotates and contacts the pressure rod, the downward force applied to the pressure rod forces the pressure rod to move downward, and the downward movement of the pressure rod brings the wolf tooth rod downward, and the wolf tooth rod moves downward.

[0008] According to the above technical solution, one end of the spring 1 is fixed on the pressure rod, and the other end of the spring 1 is fixed on the inner side of the through hole of the support rod.

[0009] According to the above technical solution, one end of the second spring is fixed on the pressure rod, and the other end of the second spring is fixed on the inner side of the feed cover.

[0010] According to the above technical solution, the knocking device includes a tamping rod, a tension spring, a pry bar, a support seat and a knocking hammer. The tamping rod passes through and slides on the bottom of the feed cover, and the tension spring is sleeved on the tamping rod.

[0011] According to the above technical solution, one end of the tension spring is fixed to the bottom of the feed cover, and the other end of the tension spring is fixed to the pry bar.

[0012] According to the above technical solution, the support seat is fixed on the machine body, a pry bar is hinged on the support seat, a striking hammer is fixed on the pry bar, and the end point of the ramming rod slides on the pry bar.

[0013] The present invention provides a cascade spiral filter press that can avoid feed blockage. It has the following beneficial effects:

[0014] (1) The present invention is provided with a stirring device. When the three-phase motor is started, the output end drives the driving wheel to rotate. The driving wheel drives the transmission wheel through the belt. The transmission wheel rotates with the rotating rod, the stirring blade and the moving block. When the stirring blade rotates, the large particles and thick parts in the material can be broken up, so that the concentration of the material is more uniform. When the moving block rotates and contacts the static block on the inner wall of the feed cover, the stirring blade and the moving block will slide to the left. When the moving block rotates away from the static block on the inner wall of the feed cover, the stirring blade will be reset by the force of the left sliding spring. When the rotating rod rotates, as the moving block and the static block keep contacting and moving away, the stirring blade can rotate and move left and right at the same time, so that the material at the center can move to the surroundings, so that the material mixing is more uniform. When the material enters the leakage pipe, it will not be blocked by large particles and some materials that are too thick, thereby improving work efficiency.

[0015] (2) The present invention is provided with a pounding device. When the end point of the stirring blade rotates and contacts the pressure rod, a downward force is applied to the pressure rod, forcing the pressure rod to move downward. The downward movement of the pressure rod brings the wolf tooth rod downward. The wolf tooth rod moves downward, bringing the coarse particles in the material to pound downward, and the coarse particles will not block the leakage pipe, making the material transmission more unobstructed. As the end point of the stirring blade moves away from the pressure rod, the pressure rod will be reset due to the pulling force of springs one and two. As the stirring blade keeps rotating, the end point of the stirring blade keeps contacting and moving away from the pressure rod, causing the wolf tooth rod to pound up and down reciprocatingly, bringing the coarse particles downward, making the material transmission unobstructed and not blocking the leakage pipe, thereby improving work efficiency.

[0016] (3) The present invention is provided with a knocking device. When the pressure rod moves downward, it compresses the tamping rod to move downward. The downward movement of the tamping rod compresses the prying rod. When the prying rod is subjected to the pressure of the tamping rod, it rotates at the hinge of the support seat. The rotation of the prying rod drives the knocking hammer upward. The knocking hammer moves upward to knock the bottom of the feed hood, giving vibration to the bottom of the feed hood, so that the sediment at the bottom of the feed hood is freed and more fully integrated into the material. When the pressure rod in the tamping device is reset, the tamping rod is not subjected to the pressure of the pressure rod. The tension spring acts on the prying rod and the tamping rod to reset. As the pressure rod keeps moving up and down, it drives the knocking hammer in the knocking device to knock back and forth on the bottom of the feed hood, so that the sediment at the bottom of the feed hood is freed, the material density in the feed hood is more uniform, the material transmission is smoother, and the leakage pipe will not be blocked, thereby improving work efficiency.

When the three-phase motor 3 is working, the three-phase motor 3 drives the power rod 8 and the rotary blade 9 to rotate. When the material flows from the feed cover 6 to the leakage pipe 15 and enters the body 4, the dehydration filter 10 plays the first step of filtering. The rotary blade 9 drives the material to push, and the outer movable ring 17 moves left and right against the static ring 11, and the water flows out. As the material is pushed along the rotary blade 9, the gap at the end of the rotary blade 9 becomes smaller, and the solid particles are discharged through the negative pressure plate 7. When the three-phase motor 3 is working, the output end drives the driving wheel 121 to rotate, and the driving wheel 121 drives the transmission wheel 123 through the belt 122. The transmission wheel 123 rotates with the rotating rod 124 and the stirring blade 126 and the moving block 1 27 rotates, when the moving block 127 rotates and contacts the static block 128 on the inner wall of the feed cover 6, the stirring blade 126 and the moving block 127 will slide to the left, and when the moving block 127 is away from the static block 128 on the inner wall of the feed cover 6, the sliding spring 125 on the left side of the stirring blade 126 will be reset due to the force, so that the stirring blade 126 can move left and right at the same time when the rotating rod 124 rotates, the support platform 1 plays a role in supporting the machine body 4 and the motor bracket 2, the motor bracket 2 plays a role in fixing the motor, and the support frame 5 plays a role in fixing the feed cover 6 to the machine body 4, so that the material at the center of the feed cover 6 can move around, and when the stirring blade 126 moves left and right and rotates at the same time, the material mixing is more uniform, and when the material enters the leakage pipe 15, it will not be blocked due to large particles and some materials that are too thick.

[0026] When the present embodiment is working, the driving wheel 121 rotates with the three-phase motor 3, and the driving wheel 121 drives the driving wheel 123 through the belt 122. The driving wheel 123 rotates with the rotating rod 124, the stirring blade 126 and the moving block 127. When the stirring blade 126 rotates, the large particles and the thick parts in the material can be broken up to make the concentration of the material more uniform. When the moving block 127 rotates and contacts the static block 128 on the inner wall of the feed cover 6, the stirring blade 126 and the moving block 127 will generate a leftward sliding thrust to make the stirring blade 126 and the moving block 127 slide to the left. When the moving block 127 is away from the static block 128 on the inner wall of the feed cover 6, the stirring blade 126 will be reset by the force of the left sliding spring 125. When the rotating rod 124 rotates, as the moving block 127 and the static block 128 keep contacting and moving away, the stirring blade 126 can move left and right while rotating, and the material at the center can be moved to the surroundings, so that the material mixing is more uniform.

[0027] See also Figure 1-Figure 6 On the basis of the above embodiment, in another embodiment of the present invention, a pounding device 13 is provided inside the feed cover 6, a knocking device 14 is fixed to the bottom of the feed cover 6, the pounding device 13 includes a support rod 131, a pressure rod 132, a spring 133, a spring 2 134 and a spike rod 135, the support rod 131 is fixed to the bottom of the feed cover 6, the support rod 131 passes through and slides with the pressure rod 132, the spike rod 135 is fixed to the pressure rod 132, one end of the spring 133 is fixed to the pressure rod 132, the other end of the spring 133 is fixed to the inner side of the through hole of the support rod 131, one end of the spring 2 134 is fixed to the pressure rod 132, and the other end of the spring 2 134 is fixed to the inner side of the feed cover 6;

[0028] When the end point of the stirring blade 126 in the stirring device 12 rotates to the bottom and contacts the pressure rod 132, the downward force applied to the pressure rod 132 forces the pressure rod 132 to move downward, and the pressure rod 132 moves downward with the wolf tooth rod 135. As the end point of the stirring blade 126 moves away from the pressure rod 132, the pressure rod 132 will be reset due to the tension of the spring 133 and the spring 2 134. When the stirring blade 126 keeps rotating, the pressure rod 132 moves downward, and the wolf tooth rod 135 stirs up and down reciprocatingly, moving the coarse particles downward, so that the material transmission is smooth and the leakage pipe 15 will not be blocked. The support rod 131 gives the spring 133 a solid effect.

[0029] The knocking device 14 includes a tamping rod 141, a tension spring 142, a pry bar 143, a support seat 144 and a knocking hammer 145. The tamping rod 141 penetrates and slides on the bottom of the feed cover 6. The tamping rod 141 is sleeved with the tension spring 142. One end of the tension spring 142 is fixed to the bottom of the feed cover 6, and the other end of the tension spring 142 is fixed to the pry bar 143. The support seat 144 is fixed to the body 4. The pry bar 143 is hinged on the support seat 144. The knocking hammer 145 is fixed on the pry bar 143. The end point of the tamping rod 141 slides on the pry bar 143.

[0030] When the pressure rod 132 in the tamping device 13 moves downward, the tamping rod 141 is pressed downward to press the prying rod 143. When the prying rod 143 is pressed by the tamping rod 141, it rotates at the hinge of the support seat 144. The prying rod 143 rotates and drives the hammer 145 to move upward. The hammer 145 moves upward to hit the bottom of the feed cover 6, giving vibration to the bottom of the feed cover 6, so that the sediment at the bottom of the feed cover 6 is freed and more fully integrated into the material. When the pressure rod 132 in the tamping device 13 is reset, the tamping rod 141 is not subjected to the pressure of the pressure rod 132, and the tension spring 142 acts on the pry rod 143 and the tamping rod 141 to reset. As the pressure rod 132 keeps moving up and down, the knocking hammer 145 in the knocking device 14 is driven to knock the bottom of the feed cover 6 back and forth, so that the sediment at the bottom of the feed cover 6 is freed, which can make the material density in the feed cover 6 more evenly distributed, and the material transmission is smoother without clogging the leakage pipe 15.

[0031] When the present embodiment is working, the pressure rod 132 is forced to move downward as the stirring blade 126 in the stirring device 12 applies a downward force to the pressure rod 132. The pressure rod 132 moves downward with the wolf tooth rod 135 moving downward. The wolf tooth rod 135 moves downward and stirs the coarse particles in the material downward, which will not block the leakage pipe 15, making the material transmission smoother. As the end point of the stirring blade 126 moves away from the pressure rod 132, the pressure rod 132 will be reset due to the pulling force of the spring 133 and the spring 2 134. While the stirring blade 126 is constantly rotating, the pressure rod 132 moves back and forth up and down, stirring the wolf tooth rod 135 back and forth up and down. The wolf tooth rod 135 stirs downward and moves the coarse particles downward, allowing the material to pass through the leakage pipe 15 more smoothly into the machine body 4, and when the pressure rod 132 moves downward, the tamping rod 141 is pressed to move downward. The tamping rod 141 moves downward to press the prying rod 143. The prying rod 143 rotates at the hinge of the support seat 144 when it is under the pressure of the tamping rod 141. The prying rod 143 rotates and drives the knocking hammer 145 to move downward. The knocking hammer 145 moves upward to knock on the bottom of the feed cover 6, giving vibration to the bottom of the feed cover 6, so that the bottom sediment in the feed cover 6 is freed and more fully integrated into the material. When the pressure rod 132 in the tamping device 13 is reset, the tension spring 142 acts on the prying rod 143 and the tamping rod 141 to reset. As the pressure rod 132 keeps moving up and down, it drives the knocking hammer 145 in the knocking device 14 to keep knocking on the bottom of the feed cover 6. The release of the bottom sediment in the feed cover 6 can make the material consistency in the feed cover 6 more evenly distributed, and the material can pass through the leakage pipe 15 more smoothly during transmission without blocking the leakage pipe 15, thereby improving work efficiency.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
