Description

Technical Field

[0001] The utility model relates to the technical field of filter press mud processing, in particular to a mud collecting vehicle. Background Art

[0002] A filter press is a common solid-liquid separation device. It is a mechanical device that uses a special filter medium to apply a certain pressure to an object to cause the liquid to seep out. For the treatment of mud after filtration, some large filter press structures are often equipped with corresponding mud discharge devices, such as mud discharge conveyor belts, forklifts, etc. However, in some small and medium-sized filter press structures, there are often no corresponding mud discharge tools to collect and transport the mud after filtration. After the mud falls to the ground, the mud can only be shoveled into the mud collection bag manually, or the mud can be taken by a bucket truck and then loaded into the mud collection bag. Finally, the mud collection bag containing the mud is transported to the corresponding processing company for processing by a trailer. The entire mud collection process is relatively troublesome, time-consuming, and consumes a lot of manpower, which is not conducive to improving production efficiency.

[0003] In order to solve the above problems, a Chinese utility model patent with application number 202021230223.4 discloses a sludge collection system for a stainless steel pickling line, which discloses a mobile hopper trolley, including a base, on which a ton bag platform is provided for placing ton bags to collect the mud material dropped after filtration by the filter press. In actual production work, a variety of mud collecting bags of different specifications may be used for mud collection. If you want to use the ton bag platform on the above mobile hopper trolley to place the mud collecting bags and complete the mud collecting work, you can only place special bags such as ton bags that can be placed on the ton bag platform without external support and keep the bag mouth open. On the contrary, the mud collecting bags commonly used in actual production work cannot be used on the above mobile hopper trolley. Therefore, the above mobile hopper trolley does not fit the actual production work well enough, has a small scope of application, has great limitations when used, and cannot meet the actual mud collection needs well.

[0029] like Figures 1 to 7 As shown, a mud collecting vehicle comprises a frame 1 and a hopper 2; wheels 3 are provided at the bottom of the frame 1, a supporting platform 11 for supporting a mud collecting bag 10 is provided on the frame 1, and the funnel 2 is provided on the frame 1 and is located above the supporting platform 11; a bag opening supporting structure 6 is also provided on the frame 1, and the bag opening supporting structure 6 is provided between the supporting platform 11 and the hopper 2, and the bag opening supporting structure 6 is used to limit the bag opening 101 of the mud collecting bag 10 from moving downward and to open the bag opening 101, so that the mud collecting bag 10 is placed upright on the supporting platform 11 and the bag opening 101 is in an open state, and when the bag opening 101 is opened, the bag opening 101 is directly opposite to the discharge port 21 of the funnel 2.

[0030] refer to Figure 7 Before collecting mud, the bag mouth support structure 6 is used to support the bag mouth 101 of the mud collecting bag 10 and maintain the bag mouth 101 in an open state. When collecting mud, the funnel 2 catches the mud material falling from the filter press, and the mud material moves downward along the inner wall of the funnel 2, and finally leaves from the discharge port 21 and falls into the mud collecting bag 10. In the mud collecting process, due to the support of the bag mouth support structure 6, the downward movement of the bag mouth 101 is limited, and the bag mouth 101 will not be driven to move downward by the mud material, so that the mud material can be smoothly loaded into the mud collecting bag 10, and then the mud collecting vehicle is pushed to the corresponding position to unload the mud collecting bag 10. The mud collecting vehicle in this embodiment can use the mud collecting bag 10 commonly used in actual production work, that is, the mud collecting bag 10 that requires external support force to stand upright and maintain the bag mouth 101 in an open state, which is more in line with the actual production work needs, has a larger scope of application, is convenient for the staff to collect mud, and is also conducive to reducing production costs and improving production efficiency.

[0031] In some specific embodiments, reference Figure 1 and Figure 2The bag mouth support structure 6 includes a support frame 62, which is used to limit the bag mouth 101 from moving downward and to open the bag mouth 101. A mud collecting port 61 is provided on the support frame 62, and the mud collecting port 61 corresponds to the position of the discharge port 21. When the mud collecting bag 10 is arranged on the support frame 62, the mud in the funnel 2 can fall into the mud collecting bag 10 through the mud collecting port 61.

[0032] Specifically, the frame 1 includes a supporting plate and a funnel mounting frame 12, wherein the supporting plate is arranged at the bottom of the frame 1, the wheels 3 are arranged at the lower side of the supporting plate, and the upper side of the supporting plate is a supporting platform 11. The supporting plate is fixedly connected to the funnel mounting frame 12, and a funnel mounting position is arranged on the funnel mounting frame 12, and the funnel mounting position is located above the supporting plate, and the funnel 2 is installed on the funnel mounting position of the funnel mounting frame 12, so that the funnel 2 is arranged above the supporting platform 11.

[0033] When collecting mud, the bottom of the mud collecting bag 10 is placed on the supporting platform 11, and the bag mouth 101 of the mud collecting bag 10 is connected to the support frame 62 by winding, hanging, etc., so that the bag mouth 101 will not fall down, so that the mud collecting bag 10 is placed upright on the supporting platform 11 and can be opened by the support frame 62.

[0034] In some specific embodiments, reference Figure 1 and Figure 2 The support frame 62 includes a plurality of support sub-frames 621 , and the support sub-frames 621 include support bars 6211 . The support bars 6211 on the plurality of support sub-frames 621 enclose and form a mud collection port 61 .

[0035] Specifically, the support frame 62 in this embodiment includes three support sub-frames 621 , and the mud collection port 61 is surrounded by three support bars 6211 .

[0036] When collecting mud, the bag opening 101 of the mud collecting bag 10 is connected to the support bar 6211 by winding.

[0037] Furthermore, gaps are left between adjacent support bars 6211. If a mud collection bag 10 with a hanging hole is needed, the hanging hole can be put on the support bar 6211 from one end to limit the downward movement of the bag opening 101, and through the cooperation of multiple hanging holes and support bars 6211, the bag opening 101 can be stretched and maintained.

[0038] In some other embodiments, the support frame 62 includes two support sub-frames 621 or more than three support sub-frames 621 , and the number of the support bars 6211 corresponds to the number of the support sub-frames 621 .

[0039] In some other embodiments, the support frame 62 includes a support ring, and the mud collecting port 61 is located on the inner side of the support ring.

[0040] In some specific embodiments, reference Figure 1 and Figure 2 The bag mouth supporting structure 6 also includes a plurality of support rods 63, and the plurality of support rods 63 correspond one to one with a plurality of support sub-frames 621. One end of the support rod 63 is provided with a support sub-frame 621, and the other end is rotatably connected to the frame 1. By rotating the support rod 63, the support bar 6211 corresponding to the support rod 63 can be moved away from or close to other support bars 6211 to adjust the size of the mud collecting port 61.

[0041] Specifically, the funnel mounting frame 12 includes four vertically extending funnel mounting rods 121, the supporting plate is in a rectangular parallelepiped shape, the four funnel mounting rods 121 are respectively arranged at the four corners of the supporting plate, and the funnel 2 is installed on the upper side of the funnel mounting rods 121. Among them, the above-mentioned support rods 63 are rotatably arranged on three of the funnel mounting rods 121.

[0042] The support rod 63 is rotatably connected to the corresponding funnel mounting rod 121, and its rotation axis extends horizontally. In the process of rotating the support rod 63 up and down, the support sub-frame 621 at the end of the support rod 63 away from the funnel mounting rod 121 is displaced in the vertical direction and in the horizontal direction, so that the corresponding support sub-frame 621 can be away from or close to other support sub-frames 621, that is, the corresponding support bar 6211 can be away from or close to other support bars 6211. Therefore, by rotating the support rod 63, the size of the material receiving opening enclosed by the three support bars 6211 can be adjusted to adapt to the mud collecting bags 10 with different bag openings 101 sizes, which is conducive to expanding the scope of application of the mud collecting vehicle, more in line with actual production work, and more convenient for staff to operate.

[0043] In some specific embodiments, reference Figure 1 and Figure 2 , the support bar 6211 extends along an arc.

[0044] Since commonly used mud collecting bags 10 basically have a circular bag opening 101 structure, the support bar 6211 is set to extend along an arc to match the bag opening 101 of the mud collecting bag 10. The bag opening 101 of the mud collecting bag 10 can be more easily fixed on the support bar 6211, and the mud collecting bag 10 will not be easily broken by the support bar 6211, which is beneficial to protecting the mud collecting bag 10.

[0045] In some other embodiments, the support bar 6211 extends in a straight line as long as it can limit the bag opening 101 of the mud collecting bag 10 from moving downward and open the bag opening 101 .

[0046] In some specific embodiments, reference Figure 1 , Figure 3 and Figure 4, and also includes a handbrake structure 4 arranged on one side of the frame 1. The handbrake structure 4 includes a pressure rod 41, a clamping rod structure and a reset spring 43. The pressure rod 41 extends in the up-down direction. The upper end and the lower end of the pressure rod 41 are respectively a down-pressing end 4111 and a braking end 4121. The frame 1 is provided with a spring sleeve 13. The reset spring 43 is arranged in the spring sleeve 13. The pressure rod 41 passes through the reset spring 43 and the spring sleeve 13 and can move up and down or rotate relative to the spring sleeve 13. The pressure rod 41 is provided with a spring limiting portion 44. The upper end of the reset spring 43 is in contact with the spring sleeve 13. The spring limiting portion 44 abuts, and the lower end of the reset spring 43 abuts against the bottom of the spring sleeve 13; the clamping rod structure includes a clamping strip 45 provided on the pressure rod 41 and a clamping slot structure 46 provided on the spring sleeve 13, the clamping strip 45 is clamped in the clamping slot structure 46 and can move along the clamping slot structure 46, the clamping slot structure 46 includes a first clamping slot 461 and a second clamping slot 462, the first clamping slot 461 extends in the up and down direction, the second clamping slot 462 extends horizontally around the circumference of the spring sleeve 13, and the lower end of the first clamping slot 461 is connected to the second clamping slot 462.

[0047] When the handbrake structure 4 is braked, the pressing end 4111 of the pressing rod 41 is pressed down, and the clamping strip 45 will also move downward along the first clamping groove 461 until it reaches the lower end of the first clamping groove 461, and the brake end 4121 also abuts against the ground. Then, the pressing rod 41 is rotated to drive the clamping strip 45 to move along the second clamping groove 462, and the clamping strip 45 will also limit the second clamping groove 462 in the up and down directions, so that the brake end 4121 remains in contact with the ground, and the mud collecting vehicle is stably stopped on the ground.

[0048] When the handbrake structure 4 is in the braking state, the pressure rod 41 is rotated to move the clamping strip 45 to the lower end of the first clamping groove 461. Then, under the action of the return elastic force of the return spring 43, the pressure rod 41 moves upward to make the brake end 4121 leave the ground and release the braking state.

[0049] When the mud collection bag 10 is full, the overall weight of the mud collection truck is relatively large, the inertia during travel is relatively large, and the truck is prone to slipping when parked due to uneven ground and other reasons. The handbrake structure 4 in this embodiment can effectively stop the mud collection truck and stabilize the mud collection truck so that it will not easily slip, which makes it convenient to control the mud collection truck and helps to reduce safety accidents.

[0050] In some specific embodiments, reference Figure 1 , Figure 3 and Figure 4The pressure rod 41 includes a first pressure rod 411 and a second pressure rod 412 arranged in sequence along the up-down direction, the first pressure rod 411 can be relatively rotatably connected to the second pressure rod 412, and the clamping strip 45 is arranged on the first pressure rod 411; the lower end of the second pressure rod 412 is a brake end 4121, and the brake end 4121 is provided with a brake frame 42, the brake frame 42 includes two brake rods 422 and a connecting rod 421 connecting the two brake rods 422, the brake rod 422 extends in the up-down direction, the brake end 4121 is fixedly connected to the connecting rod 421, and a limiting cylinder 14 is provided on the frame 1, the limiting cylinder 14 extends in the up-down direction, and the brake rod 422 passes through the limiting cylinder 14 and can move along the limiting cylinder 14.

[0051] Specifically, the first pressure rod 411 and the second pressure rod 412 are axially fixed and can rotate relative to each other. When the first pressure rod 411 is pressed down, the second pressure rod 412 moves downward synchronously; when the first pressure rod 411 is rotated, the second pressure rod 412 will not rotate under the limiting effect of the two limiting cylinders 14 on the frame 1; when the first pressure rod 411 moves upward, the second pressure rod 412 moves upward synchronously.

[0052] Further, refer to Figure 5 and Figure 6 The first pressure rod 411 and the second pressure rod 412 can be connected through the pressure rod sleeve 7. The inner wall of the pressure rod sleeve 7 is provided with an annular groove 71. The outer peripheral side of the first pressure rod 411 is provided with an annular limiting strip 4112. The annular limiting strip 4112 is arranged in the annular groove 71 and can rotate relative to the annular groove 71. The second pressure rod 412 is fixedly connected to the pressure rod sleeve 7, thereby realizing axial fixation and relative rotation of the first pressure rod 411 and the second pressure rod 412.

[0053] In some other embodiments, the pressure rod 41 is a whole, and is not divided into a first pressure rod 411 and a second pressure rod 412. Only one brake rod 422 is provided on the brake end 4121, and only one limiting cylinder 14 is provided on the frame 1. When the pressure rod 41 is pressed down, the brake rod 422 also slides in the limiting cylinder 14; when the pressure rod 41 is rotated, the brake rod 422 also rotates in the limiting cylinder 14.

[0054] In some specific embodiments, reference Figure 1 A handlebar 5 is provided on the frame 1 , and the handlebar 5 is provided on a side of the frame 1 close to the handbrake structure 4 .

[0055] The handlebar 5 is arranged on a side of the frame 1 close to the handbrake structure 4, so as to facilitate the operation of the handbrake structure 4 and to easily control the mud collecting vehicle.

[0056] In some specific embodiments, at least one wheel 3 is provided with a brake pedal.

[0057] The wheel 3 with the brake pedal can be used together with the hand brake structure 4 to form a "double insurance", making the mud collecting vehicle easier to control and avoiding safety accidents. The wheel 3 with the brake pedal can also be used alone, which is sufficient to play a role in braking stability for mud collecting vehicles with a small overall weight.

[0058] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
