Description

Technical Field

[0001] This application relates to the field of mud cake cleaning equipment technology, and in particular to a mud unloading shovel for a filter press. Background Technology

[0002] Filter presses, as common equipment in sludge dewatering processes, accumulate large amounts of sludge cake or residual sludge on the filter cloth surface and inside the equipment during operation, requiring regular manual cleaning using unloading tools. Existing unloading shovels are typically rigidly connected to their handles, which is adequate for cleaning sludge cake in flat areas, but ineffective for cleaning the horizontal or inclined areas inside the filter press. Operators can only adjust the cleaning angle by twisting their wrists or changing their posture, increasing labor intensity, reducing work efficiency, and failing to complete effective cleaning within the confined space, leading to sludge accumulation in the filter press and affecting the stability of equipment operation. Therefore, there is an urgent need for a new type of unloading shovel with an adjustable angle. Utility Model Content

Those skilled in the art can understand the specific meanings of the above in this application according to the specific circumstances.

[0045] like Figures 1-9As shown, a filter press unloading shovel in one embodiment of this application includes a sleeve 1, a handle 2 provided at one end of the sleeve 1, a shovel head 3 provided at the other end of the sleeve 1, a sliding locking seat 4 provided inside the sleeve 1, a transmission component 5 for driving the sliding locking seat 4 to move toward the shovel head 3, and an elastic element 6 for driving the sliding locking seat 4 to reset.

[0046] The shovel head 3 includes a shovel head body 31, a connector 32 connected to the shovel head body 31, and a damping ball head 33 connected to the connector 32;

[0047] The sliding locking seat 4 is provided with a receiving groove 41, and the damping ball head 33 is assembled in the receiving groove 41;

[0048] The transmission assembly 5 is located inside the sleeve 1 and is connected between the handle 2 and the sliding locking seat 4;

[0049] When the handle 2 is in the pressed state, the sliding locking seat 4 and the damping ball head 33 are in the pressed state, and the sliding locking seat 4 locks the damping ball head 33.

[0050] When the handle 2 is in the released state, the sliding locking seat 4 and the damping ball head 33 are in the loosened state, and the damping ball head 33 can rotate relative to the sliding locking seat 4.

[0051] In this embodiment, the filter press unloading shovel includes a sleeve 1, a handle 2, a shovel head 3, a sliding locking seat 4, a transmission assembly 5, and an elastic element 6. The handle 2 is located at one end of the sleeve 1, the shovel head 3 is located at the other end of the sleeve 1, the sliding locking seat 4 is located inside the sleeve 1, the transmission assembly 5 is used to drive the sliding locking seat 4 to move towards the shovel head 3, and the elastic element 6 is used to drive the sliding locking seat 4 to reset, that is, to drive the sliding locking seat 4 to move away from the shovel head 3.

[0052] The shovel head 3 includes a shovel head body 31, a connector 32, and a damping ball head 33. The connector 32 is connected to the shovel head body 31, and the damping ball head 33 is connected to the connector 32. The sliding locking seat 4 is provided with a receiving groove 41 for accommodating the damping ball head 33. The damping ball head 33 is assembled in the receiving groove 41, and the damping ball head 33 can switch states in the receiving groove 41.

[0053] The transmission component 5 is located inside the sleeve 1 and connected between the handle 2 and the sliding locking seat 4. It is used to drive the sliding locking seat 4 to move towards the shovel head 3, so as to realize the rapid angle adjustment and stable locking of the shovel head 3, thereby improving the adaptability and efficiency of the mud unloading operation.

[0054] When the handle 2 is in the pressed state, the sliding locking seat 4 and the damping ball head 33 are in the pressed state. When the sliding locking seat 4 and the damping ball head 33 are in the pressed state, the damping ball head 33 is locked by the sliding locking seat 4 and the damping ball head 33 is fixed relative to the sliding locking seat 4. When the handle 2 is in the released state, the sliding locking seat 4 and the damping ball head 33 are in the released state. When the sliding locking seat 4 and the damping ball head 33 are in the released state, the damping ball head 33 extends out of the receiving groove 41 and can rotate relative to the sliding locking seat 4, thereby driving the shovel head body 31 to rotate, so as to adjust the angle of the shovel head body 31.

[0055] like Figures 1-5 As shown, in one embodiment, the transmission assembly 5 includes a fixed push rod 51, a rotating helical gear 52 that cooperates with the fixed push rod 51, and a limiting sleeve 53 for limiting the circumferential rotation of the rotating helical gear 52.

[0056] One end of the fixed push rod 51 abuts against the handle 2, and the other end of the fixed push rod 51 is provided with an outer locking tooth 54. The rotating helical component 52 is provided with an inner helical tooth 55. The top of the outer locking tooth 54 abuts against the inclined surface of the inner helical tooth 55, and the inner helical tooth 55 can slide inside the limiting sleeve 53.

[0057] The limiting sleeve 53 is provided with a locking groove 56 and an unlocking groove 57 in sequence along the circumference. The locking groove 56 is arranged on the side close to the fixed push rod 51, and the unlocking groove 57 is arranged on the side away from the fixed push rod 51.

[0058] When the handle 2 is in the pressed state, the inner spiral tooth 55 is engaged with the locking groove 56;

[0059] When the handle 2 is in the released state, the internal spiral tooth 55 engages with the unlocking slot 57.

[0060] In this embodiment, the transmission assembly 5 includes a fixed push rod 51, a rotating helical gear 52, and a limiting sleeve 53. The rotating helical gear 52 is used to cooperate with the fixed push rod 51, and the limiting sleeve 53 is used to limit the circumferential rotation of the rotating helical gear 52. The fixed push rod 51 is disposed between the handle 2 and the rotating helical gear 52. The handle 2 and the fixed push rod 51 can be in contact or fixedly connected. The end of the fixed push rod 51 that contacts the rotating helical gear 52 is provided with an outer retaining tooth 54, while the rotating helical gear 52 is provided with an inner helical tooth 55. The top end of the outer retaining tooth 54 abuts against the inclined surface of the inner helical tooth 55. The inner helical tooth 55 can slide inside the limiting sleeve 53, so that when the fixed push rod 51 moves circumferentially, the outer retaining tooth 54 can continuously apply a circumferential turning force to the inner helical tooth 55.

[0061] The limiting sleeve 53 is provided with a locking groove 56 and an unlocking groove 57 in sequence along the circumference. The locking groove 56 is located on the side closer to the fixed push rod 51, and the unlocking groove 57 is located on the side away from the fixed push rod 51. When the handle 2 is in the pressed state, the inner spiral tooth 55 is engaged with the locking groove 56; when the handle 2 is in the released state, the inner spiral tooth 55 is engaged with the unlocking groove 57.

[0062] Specifically, when the fixed push rod 51 moves circumferentially, the outer locking tooth 54 continuously applies a circumferential turning force to the inner rotating tooth 55, causing the inner rotating tooth 55 to slide along the inner wall of the limiting sleeve 53 and sequentially enter the locking groove 56 or the unlocking groove 57. When the inner rotating tooth 55 enters the locking groove 56, the rotating tooth component 52 is restricted to a preset position, thereby driving the sliding locking seat 4 and the damping ball head 33 to be in a pressed state, realizing the fixed positioning of the shovel head 3. When the inner rotating tooth 55 enters the unlocking groove 57, the sliding locking seat 4 and the damping ball head 33 are in a released state. At this time, the damping ball head 33 can rotate relative to the sleeve 1, thereby allowing the shovel head body 31 to rotate relative to the sleeve 1 to adjust the angle of the shovel head body 31. The locking and unlocking of the shovel head 3 is realized through mechanical locking, which is simple to operate, reliable in positioning, and can effectively prevent the shovel head body 31 from shifting or loosening during use.

[0063] like Figure 1 As shown, in one preferred embodiment, the transmission assembly 5 includes a transmission inner tube 58, which is disposed between the rotating helical gear 52 and the sliding locking seat 4.

[0064] In this preferred embodiment, the transmission assembly 5 includes a transmission inner tube 58, which is disposed between the rotating helical gear 52 and the sliding locking seat 4. It is used to effectively transmit the axial movement of the rotating helical gear 52 to the sliding locking seat 4, thereby driving the sliding locking seat 4 to move along the sleeve 1 direction, realizing the locking or releasing operation of the damping ball head 33, simplifying the transmission path and improving the force transmission efficiency.

[0065] like Figure 1 , Figure 8 and Figure 9 As shown, in one embodiment, the sliding locking seat 4 is provided with a limiting groove 42 at one end that abuts against the transmission inner tube 58, and the elastic member 6 is provided on the limiting groove 42. One end of the elastic member 6 abuts against the inner wall of the sleeve 1, and the other end abuts against the limiting groove 42.

[0066] In this embodiment, the sliding locking seat 4 is provided with a limiting groove 42. The limiting groove 42 is located at the end of the sliding locking seat 4 that abuts against the transmission inner tube 58, and is used to place the elastic element 6. One end of the elastic element 6 abuts against the inner wall of one end of the sleeve 1, and the other end abuts against the limiting groove 42, which is used to drive the sliding locking seat 4 to reset. After the handle 2 is pressed, the elastic element 6 pushes the sliding locking seat 4 to reset in a direction away from the shovel head 3, thereby realizing the switching of the state of the handle 2 and facilitating the adjustment of the angle of the shovel head 3.

[0067] Specifically, when the operator needs to adjust the angle of the shovel head 3, the shovel head body 31 is first fixed. This can be done by stepping on it or by using tools to fix it in the axial direction. Then, the handle 2 is pressed, and the handle 2 pushes the fixing push rod 51. Since the top of the outer locking tooth 54 on the fixing push rod 51 abuts against the inclined surface of the inner spiral tooth 55 of the rotating spiral tooth 52, a circumferential rotational force is applied to the inner spiral tooth 55 when it is pressed. The limiting sleeve 53 is used to limit the circumferential rotation of the rotating spiral tooth 52. When the fixing push rod 51 pushes the rotating spiral tooth 52 to move axially, the inner spiral tooth 55 transitions from the locking groove 56 to the unlocking groove 57 along the inner wall of the limiting sleeve 53 under the action of the outer locking tooth 54. This causes the sliding locking seat 4 and the damping ball head 33 to change from a pressed state to a loose state. At this time, the damping ball head 33 can rotate relative to the sliding locking seat 4, thereby driving the angle adjustment of the shovel head body 31.

[0068] After adjusting to the appropriate angle, the operator then fixes the shovel head body 31. This can be done by stepping on it or by using tools to fix it axially. Then, the operator presses the handle 2 again, which pushes the fixing push rod 51. The outer locking teeth 54 on the fixing push rod 51 push the inner locking teeth 55 of the rotating gear 52 along the inner wall of the limiting sleeve 53 from the unlocking groove 57 to the locking groove 56. This causes the sliding locking seat 4 to move toward the damping ball head 33 and re-form a pressing state with the damping ball head 33, locking the damping ball head 33 and completing the angle fixing of the shovel head body 31. The operator can easily and quickly adjust and lock the angle of the shovel head 31. The operation process is simple and can effectively improve the efficiency and reliability of mud unloading operations.

[0069] In one embodiment, the sleeve 1 is a stainless steel tube.

[0070] In this embodiment, the use of stainless steel tubing 1 can significantly improve the overall strength and corrosion resistance. It is not easy to rust or deform even after long-term use in humid and muddy environments. At the same time, it reduces the overall weight, making it easier for operators to hold and operate for a long time, thus improving the overall user comfort.

[0071] In one embodiment, the transmission inner tube 58 is a plastic tube.

[0072] In this embodiment, the transmission inner tube 58 is made of plastic, such as PVC or polyoxymethylene, which has high strength, light weight, wear resistance, corrosion resistance and good self-lubrication properties. It can reduce direct friction during transmission, reduce noise and wear, thereby extending the overall service life and improving the smoothness and comfort of operation.

[0073] In one embodiment, a rubber gasket is provided between the sleeve 1 and the transmission inner tube 58.

[0074] In this embodiment, a rubber gasket is provided between the sleeve 1 and the transmission inner tube 58, which can effectively absorb the vibration and impact during the transmission process, reduce the noise during operation, reduce the friction between the sleeve 1 and the transmission inner tube 58, reduce wear, and the rubber gasket has a certain sealing and buffering effect, which can further improve the comfort and durability of the mud unloading shovel.

[0075] In one embodiment, an anti-slip damping ring is provided between the sliding locking seat 4 and the damping ball head 33.

[0076] In this embodiment, an anti-slip damping ring is provided between the sliding locking seat 4 and the damping ball head 33. This ring can provide higher friction in the pressed state, preventing the damping ball head 33 from rotating unexpectedly when under force. At the same time, in the released state, the anti-slip damping ring provides a certain damping effect, making the angle adjustment process of the shovel head body 31 more stable and controllable, avoiding the problem of inaccurate positioning caused by excessively fast rotation, and improving the safety and accuracy of operation.

[0077] In one embodiment, the shovel body 31 is made of plastic material.

[0078] In this embodiment, the shovel head body 31 is made of plastic material, such as polyoxymethylene, which has the characteristics of high strength, wear resistance, low coefficient of friction, low water absorption and corrosion resistance. It can significantly reduce the overall weight of the shovel and reduce the fatigue of users during long-term operation. At the same time, the plastic material has excellent wear resistance and corrosion resistance, which can effectively extend the service life of the shovel head body 31 and reduce the maintenance frequency. Furthermore, when the plastic material comes into contact with other components such as filter plates of filter presses, it can significantly reduce surface damage and improve the safety and reliability of operation.

[0079] In one embodiment, the outer surface of the sleeve 1 is provided with an anti-slip coating.

[0080] In this embodiment, the outer surface of the sleeve 1 is provided with an anti-slip coating, which can increase the grip friction in wet or muddy environments, prevent the operator from slipping, and thus improve the safety and stability of use. The anti-slip coating can be a polyurethane coating, which has the characteristics of wear resistance, oil resistance and high anti-slip performance.

[0081] In one embodiment, the handle 2 is a rubber handle.

[0082] In this embodiment, the handle 2 is supported by rubber material, which has good anti-slip performance and can be held stably even in wet or muddy environments. At the same time, the rubber handle has a soft grip, which can effectively relieve hand fatigue caused by long-term operation and improve work efficiency and safety.

[0083] As needed, the above technical solutions can be combined to achieve the best technical effect.

[0084] The above description is merely the principle and preferred embodiment of this application. It should be noted that for those skilled in the art, implementation methods obtained by appropriately combining the technical solutions disclosed in different embodiments are also included within the technical scope of this invention. Based on the principle of this application, several other modifications can also be made, which should also be considered within the protection scope of this application.
