Description

Technical Field

[0001] This utility model relates to a device for conveying slurry-like objects, belonging to the technical field of conveying slurry-like objects. Background Technology

[0002] The existing devices for conveying slurry-like objects in the domestic and international markets include plunger pumps, screw pumps, centrifugal pumps, gear pumps, and Roots pumps. Due to their structural principles, these devices suffer from low efficiency, safety hazards, a high rate of friction damage to the conveyed object, and high power consumption.

[0003] The existing screw pump for conveying emulsion explosives has the following drawbacks due to the screw's close contact with the high-speed rotation of the rubber-sleeved stator: (1) Friction generates high temperature and pressure, which can easily detonate the emulsion explosives, leading to accidents involving people and objects; (2) Part of the conveyed emulsion explosives breaks down (water phase breaks down), resulting in a reduction in blasting power; (3) The rubber-sleeved stator, due to its elasticity, will create gaps with the screw during conveying, resulting in low conveying efficiency; (4) For the same amount of conveying time, the power consumption is more than twice that of the device of this invention; (5) The rubber-sleeved stator is prone to damage.

[0004] The disadvantages of existing plunger pumps for conveying emulsion explosives are: (1) At the same conveying volume, the number of reciprocating motions is more than ten times that of the device invented in this invention. In addition, the internal components have a larger contact friction area than those of the device invented in this invention, making it more prone to high temperature and high pressure leading to explosion accidents. Therefore, the device invented in this invention is safer, more efficient and energy-saving than the plunger pump. (2) The device invented in this invention has a smaller demulsification coefficient and higher explosive power when conveying emulsion explosives than the plunger pump. (3) In practical applications, plunger pumps cannot convey high-viscosity finished emulsion explosives, but can only convey semi-finished emulsion explosives. The viscosity of finished emulsion explosives is 300 centipoise to 500 centipoise, and the viscosity of semi-finished emulsion explosives is 150 centipoise to 250 centipoise. Therefore, it is crucial to develop a device for conveying slurry-like objects. Utility Model Content

[0005] This invention addresses the shortcomings of the prior art by providing a device for conveying slurry-like objects. The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A device for conveying a slurry-like object includes a conveying pump body and a piston movably connected to the conveying pump body. The conveying pump body has an inlet and an outlet at both ends. The inlet at both ends is provided with an inlet check valve A and an inlet check valve B, respectively. The outlet at both ends is provided with an outlet check valve A and an outlet check valve B, respectively. The outlet ends of the outlet check valve A and the outlet check valve B are connected to an outlet pipe. The piston is provided with a driving mechanism.

[0006] Furthermore, the feed check valve A and feed check valve B are equipped with hoppers that communicate with the conveying pump body.

[0007] Furthermore, the feed check valve A and feed check valve B are respectively equipped with hoppers that are connected to the conveying pump body.

[0008] Furthermore, both the feed one-way valve A and the feed one-way valve B are equipped with a cleaning valve for cleaning the conveying pump body at their feed ends.

[0009] Furthermore, the cleaning valve includes a feed gate valve and a cleaning gate valve, with the cleaning gate valves at both ends located between the feed check valve A and the feed gate valve, and between the feed check valve B and the feed gate valve, respectively.

[0010] Furthermore, the drive mechanism includes a transmission cylinder connected to the piston, and the transmission cylinder is connected to the piston through a transmission joint.

[0011] Furthermore, both the transmission cylinder and the delivery pump body are equipped with position sensors for controlling the direction and position of piston movement.

[0012] Furthermore, the transmission cylinder can be replaced by a pneumatic cylinder, an electric cylinder, or a linear drive mechanism capable of linear reciprocating motion.

[0013] Furthermore, the linear drive mechanism is a combination of a motor, a gearbox, and a connecting rod, wherein the motor is a pneumatic motor, a linear motor, or an electric motor.

[0014] Furthermore, a temperature sensor, a pressure sensor, and a pressure relief valve are installed on the discharge pipe.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. The pump body can be cylindrical, with two feed check valves and two discharge check valves installed on the cylindrical surface. The piston inside the pump body is driven back and forth by the drive mechanism. The piston divides the pump body into two chambers. The reciprocating movement of the piston causes the pressure in the two chambers to change accordingly. 2. The reciprocating motion of the piston enables the transport of objects; the slow movement of the piston reduces the contact area between the piston and the inside of the pump body, thereby reducing mechanical friction and improving the safety factor, while also reducing the damage rate of the transported objects. 3. The slow piston movement and low required transmission power effectively reduce noise and achieve energy-saving effects. 4. The piston is located between feed check valve A and feed check valve B. Feed check valve A and feed check valve B are respectively connected to a hopper. The two hoppers, two feed inlets and two discharge outlets enable the simultaneous quantitative conveying of two different objects. Attached Figure Description

[0023] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0024] like Figures 1-6As shown, a device for conveying a slurry includes a conveying pump body 2 and a piston 13 movably connected to the conveying pump body 2. The conveying pump body 2 has an inlet and an outlet at both ends. The inlet at both ends is provided with an inlet check valve A 6 and an inlet check valve B 7, respectively. The outlet at both ends is provided with an outlet check valve A 8 and an outlet check valve B 9, respectively. The outlet ends of the outlet check valve A 8 and the outlet check valve B 9 are connected to the outlet pipe 10. The piston 13 is provided with a driving mechanism. The conveying pump body 2 of this application can be cylindrical, with two feed one-way valves (feed one-way valve A 6 and feed one-way valve B 7) and two discharge one-way valves (discharge one-way valve A 8 and discharge one-way valve B 9) installed on the cylindrical surface. The piston 13 inside the conveying pump body 2 is driven reciprocally by the drive mechanism. The piston 13 divides the interior of the conveying pump body 2 into two chambers. The reciprocating movement of the piston 13 causes the pressure in the two chambers to change accordingly. The reciprocating motion of the piston 13 realizes the conveying of objects. The slow movement of the piston 13 reduces the contact area between the piston 13 and the interior of the conveying pump body 2, reduces mechanical friction, thereby improving the safety factor and reducing the damage rate of the conveyed objects. The slow movement of the piston 13 and the small transmission power required effectively reduce noise and achieve energy saving. The piston 13 is located between feed one-way valve A 6 and feed one-way valve B 7. Feed one-way valve A 6 and feed one-way valve B 7 are respectively connected to one hopper 1. The two hoppers 1, two feed inlets and two discharge outlets realize the simultaneous quantitative conveying of two different objects.

[0025] The feed check valve A 6 and feed check valve B 7 are equipped with hoppers 1 that are connected to the conveying pump body 2.

[0026] like Figure 4 As shown, the feed check valve A 6 and feed check valve B 7 are respectively equipped with hoppers 1 that are connected to the conveying pump body 2. They are used to simultaneously and quantitatively convey two different objects.

[0027] Both the feed one-way valve A 6 and the feed one-way valve B 7 are equipped with a cleaning valve 5 for cleaning the conveying pump body 2 at their feed ends.

[0028] The cleaning valve 5 includes a feed gate valve 51 and a cleaning gate valve 52. The cleaning gate valves 52 at both ends are located between the feed check valve A 6 and the feed gate valve 51, and between the feed check valve B 7 and the feed gate valve 51, respectively. The cleaning valve 5 is used to clean residual materials inside the conveying pump body 2. By closing the feed gate valve 51, which is connected to the hopper 1, and opening the cleaning gate valve 52, which is connected to the flushing liquid, the inside of the conveying pump body 2 can be cleaned quickly.

[0029] The drive mechanism includes a transmission cylinder 3 connected to the piston 13, and the transmission cylinder 3 is connected to the piston 13 through a transmission joint 4.

[0030] Both the transmission cylinder 3 and the delivery pump body 2 are equipped with position sensors for controlling the movement direction and position of the piston 13.

[0031] The transmission cylinder 3 can be replaced by a pneumatic cylinder, an electric cylinder, or a linear drive mechanism capable of linear reciprocating motion. The linear drive mechanism is a combination of a motor, a gearbox, and a connecting rod; the motor can be a pneumatic motor, a linear motor, or an electric motor. The transmission mechanism is not limited to those listed herein; it can be replaced with a mechanism that matches the design and installation requirements as needed.

[0032] A temperature sensor 12 is provided on the discharge pipe 10, and a pressure sensor 14 and a pressure relief valve 11 are also provided on the discharge pipe 10.

[0033] Working principle: When piston 13 moves towards feed check valve A6 under the drive of transmission cylinder 3, the positive and negative pressures of the objects on both sides of piston 13 change accordingly, thereby closing feed check valve A6 and discharge check valve B9. At this time, the power source is the positive pressure of the objects, which returns the pressure springs of feed check valve A6 and discharge check valve B9 to close. At the same time, feed check valve B7 and discharge check valve A8 open. At this time, the power source is the negative pressure of the objects. The conveyed objects pass from hopper 1 through feed gate valve 51 on the feed check valve B7 side and feed check valve B7 to fill the inner cavity of the conveying pump body 2 near feed check valve B7 side. At the same time, the objects in the inner cavity of the conveying pump body 2 near feed check valve A6 side pass through discharge check valve A8, temperature sensor 12 and pressure relief valve 11 and are squeezed out from the discharge end of discharge pipe 10. Pressure sensor 14 can be added to discharge pipe 10 to protect against overpressure.

[0034] When piston 13 moves towards feed check valve B7 under the drive of transmission cylinder 3, the positive and negative pressures of the objects on both sides of piston 13 change accordingly, thereby causing feed check valve B7 and discharge check valve A8 to close. At this time, the power source is the positive pressure of the object, which returns the pressure springs of feed check valve B7 and discharge check valve A8 to close. At the same time, feed check valve A6 and discharge check valve B9 open. At this time, the power source is the positive pressure of the object. The conveyed object passes through the feed gate valve 51 on the feed check valve A6 side and feed check valve A6 to fill the inner cavity of the conveying pump body 2 near feed check valve A6 side. At the same time, the object in the inner cavity of the conveying pump body 2 near feed check valve B7 side passes through discharge check valve B9, pressure sensor 14 and pressure relief valve 11 and is squeezed out from the discharge end of discharge pipe 10.

[0035] Compared with screw pumps and plunger pumps, this application offers advantages such as slow yet efficient operation, low noise, safety, energy saving and environmental friendliness, and simple structure. It also has wide applications in industries such as petroleum, chemical, food, pharmaceutical, fire fighting, rescue, manufacturing, civil explosives, and military; used for conveying liquids, slurries with high viscosity, flammable and explosive materials, emulsion explosives, or highly corrosive substances. This application effectively solves the safety hazards of existing devices on the market, including high friction damage to the conveyed object, easy corrosion of the conveying device, high power consumption, and low conveying efficiency.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
